今天剛剛上班，小徒弟跑過來：師父今天我看到船臺(tái)的那條快下水的船很奇怪，好好的螺旋槳又是打砂又是噴漆。這不是畫蛇添足嗎？
Todaywhen I just to begin the work, the small disciple come to ask me: master, I sawthe berth of the quick launching ship is very strange, the good propeller is sandingand painting. This is not really gild the lily?
（照片里螺旋槳上做成了白色油漆）

徒弟這哪是畫蛇添足?。∵@是在給螺旋槳噴涂有機(jī)硅防污漆。
Myapprentice, This is spraying coating a silicone anti fouling paint on thepropeller and not gild the lily!

小徒弟有點(diǎn)蒙圈，不停的問。
Heis a little confused and still ask me.
螺旋槳不是銅的嗎？
Isthe propeller not made by brass?
銅質(zhì)螺旋槳一般不會(huì)生銹那為什么還要噴漆?。侩y道螺旋槳也需要防污漆的保護(hù)？
Copperpropeller will not rusty why should we painting? Does the propeller alsorequire the protection of antifouling paints?
那螺旋槳上噴的是什么漆？
Whatkind of painting should the propeller use?
哪家油漆公司的漆質(zhì)量可靠性價(jià)比高?。?

螺旋槳涂裝時(shí)要注意些什么？
Whatshould pay attention to when painting the propeller？
這一連串的問題也叫我這師父一時(shí)無從入手難以回答。畢竟螺旋槳噴漆不常見，大部分人不完全了解也很正常?，F(xiàn)在拿徒弟提出的問題，給大家介紹下螺旋槳噴涂有機(jī)硅防污漆，有說的不對(duì)或需要補(bǔ)充之處請(qǐng)回帖！
Thisseries of problems also made me unable to know how to answer. After all,propeller spraying is not common, it is also very normal that most people donot fully understand. Now take my apprentice’s questions for example, I willintroduce the propeller spraying silicone antifouling paint, if I said thewrong or you want to supplement the department, please give me some replies!
船舶螺旋槳將推力傳給船體本身驅(qū)動(dòng)船舶航行，它是把船舶發(fā)動(dòng)機(jī)產(chǎn)生的力矩轉(zhuǎn)變成動(dòng)能的重要部件。螺旋槳的重要性不用多說大家都知道，它的好壞直接影響整條船的工作狀態(tài)。
Shippropeller thrust will be transferred to the ship itself and drive the ship,which is an important part that converts torque developed by ship engine intokinetic energy. The importance of the propeller is needless to say. And it hasthe most important effects on the work status of the whole ship.
螺旋槳是不是銅的？
船用螺旋槳主要材料是銅，但是根據(jù)不同的船型和需求。船舶螺旋槳銅的材料又分為錳青銅、鎳錳青銅、鎳鋁青銅、錳鋁青銅這四種！這里就不一一介紹這些材料的區(qū)別了。有興趣的讀者自己去找找相關(guān)資料，了解下!
銅質(zhì)螺旋槳一般不會(huì)生銹那為什么還要噴漆?。侩y道螺旋槳也需要防污漆的保護(hù)？
Isthe propeller made by brass?
Themain material of marine propeller is brass. But based on different ship typesand requirements, the material of the ship propeller is aluminum bronze. I willnot introduce their differences one by one. If you have interest, you may getsome relevant information to know about it.
Generally,brass propeller will not rust, but why painting? Does propeller also requirethe protection of antifouling paints? divided into four kinds, which are manganese bronze, nickelmanganese bronze, nickel aluminum bronze and manganese
不要以為螺旋槳主要成分是銅就不會(huì)長(zhǎng)海洋生物，恰恰相反在船舶停航并且外部環(huán)境很適合海洋生物的生長(zhǎng)（如夏季水溫適宜、又地處江河湖等淡水入?？?、營(yíng)養(yǎng)化嚴(yán)重的水域、長(zhǎng)期停航）。螺旋槳上生長(zhǎng)的海洋生物會(huì)叫人難以想象。 Don’t think that propeller doesn’t grow marineorganisms because ofits main component of brass. On the contrary, when the ship is suspended, theexternal environment is very suitable for their growth (for example suitablewater temperature in summer, at such asrivers, lakes and other fresh water into the sea mouth, in severe-eutrophic water,and be long-term suspended). The growth of marine organisms on the propeller ishard to imagine.
照片里這條船是條新造船，下水后碼頭舾裝到試航大概用了2個(gè)多月時(shí)間。在試航時(shí)發(fā)現(xiàn)航速嚴(yán)重不達(dá)標(biāo) (設(shè)計(jì)最高航速15節(jié)實(shí)際上拼盡全力也只能達(dá)到11節(jié)，這樣的結(jié)果無論那個(gè)船東都是不能接受的) 、整船震動(dòng)大、主機(jī)油耗超標(biāo)等問題。導(dǎo)致試航失?。』睾胶筮M(jìn)塢排查原因。
Theboat in the picture is a new ship, and it took about 2 months from outfittingto trial trip. On its trials run, some problems were found that the speed wassub-standard seriously (a designed maximum speed of 15 knots actually can onlyreach 11 knots, and this result was not acceptable), the entire ship hadvibration, and engine fuel use exceeded. The trial resulted in failure. Afterits return, it was docked for inspecting.
發(fā)現(xiàn)螺旋槳怎么和正常的螺旋槳不大一樣，上面好像有很多的附著物！ It’sfound that the propeller is abnormal because much dirt was attached on it。
整個(gè)螺旋槳上正面、反面、甚至槳尖上都不能幸免。長(zhǎng)滿了海洋生物～～～滕壺。螺旋槳的外形因?yàn)殚L(zhǎng)滿了附著物已經(jīng)發(fā)生了改變，船舶的航速油耗受到影響也就順理成章了。由此可見船舶螺旋槳的防污是多么的重要。
Boththe front and back walls are not immune, even the helical tip。They are covered bya marine organism named barnacle。Because of theattached plant, the propeller’s outline has changed, The navigational speed andfuel consumption rate would certainly be bad. Thus it can be seen thatantifouling for propeller was so important.
螺旋槳不會(huì)生銹但是會(huì)因?yàn)槁菪龢目张莠F(xiàn)象，對(duì)螺旋槳照成嚴(yán)重的侵蝕。船舶大型化和高速化使得螺旋槳負(fù)荷不斷增加，尾部流場(chǎng)的不均勻性使得螺旋槳上產(chǎn)生時(shí)生時(shí)滅的空泡。由于空泡潰滅產(chǎn)生內(nèi)爆，這種內(nèi)爆之沖擊力反復(fù)集中于一點(diǎn)，槳葉表面反復(fù)侵蝕后形成多孔的海綿狀麻點(diǎn)。導(dǎo)致螺旋槳侵蝕損傷。
Whilecopper propeller does not rust, it also can be eroded seriously by cavitation. Forthe vessel are more and more huge and fast, the propeller’s load are addedaccordingly, the aft flow field to be more unstable, much cavitation will begenerated on the surface of propeller, they grow up and crush out. Forthe vessel are more and more huge and fast, the propeller’s load are addedaccordingly, the aft flow field to be more unstable, much cavitation will begenerated on the surface of propeller, they grow up and crush out. Thecrush of cavitation will lead an implosion, if the implosion force converge onone point repeatedly, some spongy pits will generated on the propeller bladesurface, result in a eroded damage.
空泡現(xiàn)象對(duì)螺旋槳的危害可見一般，母材受損照成螺旋槳原本光滑光順的表面物理外形發(fā)生改變。船舶航速降低、主機(jī)負(fù)荷增加、油耗越來越嚴(yán)重。全新的螺旋槳每一片槳葉重量都是一致，經(jīng)過動(dòng)平衡和靜平衡試驗(yàn)才能安裝到船上。此時(shí)的螺旋槳到達(dá)最佳的工作狀態(tài)。船舶航行一段時(shí)間，因空泡現(xiàn)象螺旋槳每一片槳葉都受到不同程度的侵蝕受損，重量發(fā)生了不同程度的改變。由于受空泡現(xiàn)象侵蝕后的螺旋槳每一片槳葉的重量各不相同，造成螺旋槳?jiǎng)悠胶忪o平衡都隨之發(fā)生改變。對(duì)船舶的主機(jī)和軸系都帶來了很大影響。遇到這種情況只能進(jìn)塢修理。輕者簡(jiǎn)單維修，重者直接報(bào)廢更換新的螺旋槳。即使進(jìn)行了維修，修好后經(jīng)過一段時(shí)間的航行。螺旋槳還會(huì)因空泡現(xiàn)象螺旋槳再次侵蝕受損。船舶頻繁進(jìn)塢維修整個(gè)運(yùn)營(yíng)的成本攀升！
Therebyit can be concluded that the cavitation was so dangerous, if the base metal hadbeen damaged, the original smooth physical surface outline will be changed tounsatisfactory.
Thenavigational speed will be reduced, M/E load will be added, Fuel consumptionrate will be also added. For one new propeller, each blade hasequal weight, they are fitted on vessel under a reasonable dynamic balance andstatic balance test. Then the propeller can work in the best case. Aftera period of sailing, for the reason of cavitation, each blade was damaged in adifferent level, their weight changed different also, lead a unexpected changeof dynamic damage to the M/E and shaft system. In this case, the vesselshould dry docking repairs. In less severe case, a simple repair was necessary,in severe case, the propeller should be replaced. Even so, after a period oftime, the propeller will be damaged again. Obviously, so much drydocking repairs were expensive.
那螺旋槳上噴的是什么漆？
螺旋槳上噴涂的是有機(jī)硅防污涂料。
如果能在螺旋槳上做上彈性非常好表面非常光滑的有機(jī)硅涂料，能有效的防止螺旋槳的空炮侵蝕。當(dāng)空泡現(xiàn)象發(fā)生時(shí)，螺旋槳流場(chǎng)爆裂的空泡產(chǎn)生的沖擊力作用到有機(jī)硅涂層表面。有機(jī)硅涂層有其他涂料無法比擬的彈性，表面非常光滑會(huì)不斷地緩沖這股沖擊力。使得螺旋槳本身不會(huì)因?yàn)榭张莠F(xiàn)象而侵蝕。好比給螺旋槳穿上了一件由凱夫拉 （ KEVLAR ） 制成的防彈衣。保證了螺旋槳的正常工作狀態(tài)。船舶的運(yùn)營(yíng)維修費(fèi)用大大降低，經(jīng)濟(jì)性顯著提高。
What’sthe paint spray on the propeller?
It’sorganosilicon anti-fouling coatings.
If the silicone paint sprayed on the propeller couldmake the surface of it smooth and elastic, the propeller can prevent the cavitation erosioneffectively. When the cavitation generating, the implosion force acton the organosilicon anti-fouling coatings surface, because of the goodelasticity, the implosion force will be cushioned, thus the propeller will beprotected. It is liked put a body armour made by KEVLAR on thepropeller, ensure a best work condition for it. The repair cost will be reducedgreatly and economical efficiency added remarkable also.

（船舶螺旋槳做有機(jī)硅防污漆航行32個(gè)月后照片） （The picture of shippropeller make silicone antifouling 32 months after sailing）
據(jù)中塗化工涂料CHUGOKU【CMP】 提供的資料，螺旋槳上涂有機(jī)硅涂料能有效的阻隔空泡侵蝕，螺旋槳使用年限對(duì)比沒有涂有機(jī)硅涂料的提高數(shù)倍.
Accordingto the information of CMP, Propeller on coated organic silicone coating caneffectively block the cavitation erosion，The time of years that propeller can use isseveral times higher than that of without painting organic silicone coating.
船用螺旋槳噴涂的主要涂料是有機(jī)硅防污漆。與傳統(tǒng)的防污漆不同，有機(jī)硅防污漆防污機(jī)理完全依賴涂層表面非常光滑。海洋生物無法附著到光滑的表面，即使附著上也無法立足生長(zhǎng)。而傳統(tǒng)自拋光水溶型防污漆，是通過基料與海水反應(yīng)和溶解，通過毒素滲析殺死海洋生物達(dá)到防污的目的。
Marinepropeller spraying coatings are mainly organic silicon antifouling paints.Different from traditional antifouling paint，Silicone antifouling paint’s antifoulingmechanism completely depend on the coating surface which is very smooth，The surface of the sea creatures can’t attached to the smooth，Even attach it cannot based on growth. Since the traditionalpolishing type water soluble antifouling is through base reaction with waterand dissolve，By toxins kill Marine life to achieve thepurpose of antifouling dialysis.
有機(jī)硅防污涂料也可以作為整船的防污涂料來使用，它有以下特點(diǎn)： Silicone antifouling paint can also be used as the ship of antifouling paint has the following features:
1.無毒。由于低表面能涂料的作用機(jī)理沒有化學(xué)因素，因此有機(jī)硅涂料不含任何毒料如：氧化亞銅、有機(jī)錫或者其他殺
蟲劑！不受當(dāng)前國(guó)際海洋環(huán)境法規(guī)和公約的限制。是目前最環(huán)保的防污漆。
1．Non-poisonous. Dueto the low surface energy coating mechanism of no chemical factors, Organic siliconcoating does not contain any toxic materials such as: cuprous oxide、Organic tin or other pesticides！Not limitedby the current international Marine environmental regulations and conventions. Sothis is the most environmentally friendly antifouling paint.
2.自拋光。有機(jī)硅防污涂料涂層表面非常光滑不粘海洋生物，即使附著上只要船舶達(dá)到一定航速，表面就可以自行清潔。海洋生物很容易就被水流沖刷掉。始終保持涂層表面光滑性。
2. Self-polishing. Silicone antifouling paint coating surface is very smoothand not sticky of Marine biology，Even attach as long asthe ship reached a certain speed, the surface can clean itself. Marine life iseasy to wash away by water. Always keep the coating surface smoothness.
3.有機(jī)溶劑（VOC）含量低，低表面能有機(jī)硅防污涂料一般固體含量都超過70%。VOC含量很低，對(duì)施工人員的身體健康和和環(huán)境負(fù)面影響都很小。 3.Organic solvents (VOC) content is low，Generally low surface energy silicone antifouling coatings this more than 70%. With is low content of VOC，it has little harm to the wokers’health and the environment.
4.保護(hù)周期長(zhǎng)。有機(jī)硅防污涂料一般的有效期為5年，5年以后，由于使用中有一定的損傷需要重新修補(bǔ)。修補(bǔ)后有可獲得5年的有效期。一般的船舶壽命大概在25-30年。也就是說在整個(gè)使用壽命中做5-6次涂層修補(bǔ)即可。 4.The cycle of protect is long. Silicone antifouling coatings in general will be valid for 5 years，5 years later，Due to the certain damage of using needs to be repaired. The validity of the repair can be obtained after 5 years. The lifetime of the ship is 25-30 years in genneral. That is to say, it only have to do 5-6 times coating repair in the whole service life of the ship.
5.節(jié)能經(jīng)濟(jì)。由于船舶使用了有機(jī)硅涂料防污，涂層表面非常光滑。有資料表面如果整個(gè)船底都采用有機(jī)硅防污涂料，能節(jié)約燃油5%甚至有的船型能打到6%以上。特別是如果螺旋槳采用有機(jī)硅涂料大大降低了空泡現(xiàn)象對(duì)螺旋槳的侵蝕，保證了船舶最佳的航行狀態(tài)。經(jīng)濟(jì)方面得到了很大的提升。
5.Energy-economy. Becauseof using the organic silicone antifouling coatings，The coating surfaceis very smooth. Data indicated that if the entire bottom using siliconeantifouling paint can save fuel above 5%-6%. If the propeller using siliconecoating， Cavitation erosion of propeller is reducedgreatly to ensure the best state of navigation of the ship. It is benefit forthe economic growth.
哪家油漆公司的有機(jī)硅涂料質(zhì)量可靠性價(jià)比高啊？
Whichpaint company silicone coating quality reliable and cost-effective?
目前國(guó)際上比較著名的幾大油漆公司中塗、國(guó)際、佐敦等都有此類產(chǎn)品推出。在實(shí)際應(yīng)用中中塗化工CHUGOKU 【CMP】的有機(jī)硅涂料質(zhì)量有保障價(jià)格相對(duì)適中。很多大型國(guó)際航運(yùn)公司都在采用他們的產(chǎn)品。
Currently，most famousinternational paint company such as CMP, IP, Joton, etc. Have such productslaunched. In practical application the silicone paint produced by the chemicalindustry CHUGOKU [CMP] has a high quality and a reasonable price. Many biginternational shipping companies are using their products.
螺旋槳噴涂有機(jī)硅防污涂料施工時(shí)要注意些什么？
Whatshould be paid attention to when the propeller is sprayed with silicone antifouling painting?
有機(jī)硅防污涂料表面能非常低，其對(duì)基材結(jié)合力不是很好。故對(duì)整個(gè)涂裝施工過程要求非常嚴(yán)格。下面我就用中塗化工CHUGOKU 【CMP】的有機(jī)硅防污涂料的技術(shù)要求，來給大家講一下有機(jī)硅防污涂料涂裝施工注意事項(xiàng)！
Siliconeanti fouling painting has a very low surface energy and can be well binded withthe base material.so the whole process of painting has a very strictrequirement. Now I will take the CHUGOKU[CMP] silicone anti fouling paintingfor example to introduce the technical requirements when painting and giveyou a talk about what should take into considerationwhen use the silicon anti fouling painting.
1. 涂裝施工前對(duì)螺旋槳表面進(jìn)行高壓淡水清洗清潔。
螺旋槳在加工和安裝過程中有很多的拋光膏、油污、不容易除去的灰塵顆粒等不利于涂裝的表面殘留。這些殘留必須徹底清除。先用高壓淡水清洗除去螺旋槳表面的灰塵污垢和微量鹽分。再用稀釋劑擦拭清潔表面的油污，拋光膏等殘留。
1.The propeller surface should becleaned with high pressure freshwater before spraying painting. In the processof making and install the propeller, it has a lot of polishing paste, oil, dusthard to remove, which is harmful to the spray process, so the residues on thesurface of the propeller should be removed absolutely. First, remove dirt andsalt from the surface of the propeller by using high pressure fresh water, thenwipe the polishing paste and other residues on the surface with diluent.

（The picture of propellercleaning before）
（清潔后螺旋槳照片）
（The picture of propellercleaning after）
2. 螺旋槳噴涂有機(jī)硅防污涂料前,鄰近區(qū)域的漆膜應(yīng)充分保護(hù)。并同時(shí)搭設(shè)施工防護(hù)棚。
有機(jī)硅防污涂料施工過程中，要求對(duì)周圍環(huán)境嚴(yán)格保護(hù)。不能污染其他區(qū)域。有機(jī)硅防污涂料成膜后，表面非常光滑、不粘性極強(qiáng)，很難和其他油漆融合。一旦飄落到其他油漆表面必須進(jìn)行徹底的清除否則將不法進(jìn)行復(fù)涂。所以必須對(duì)其他油漆表面進(jìn)行細(xì)致徹底的保護(hù)。搭設(shè)防護(hù)棚一定要做到全覆蓋無縫隙！
2.The paint film of the adjacent areashould be fully protected before the propeller is sprayed with silicon antifouling paint and to build a protective shed when painting at the same time.
Inthe process of spraying silicone anti fouling paint, the surrounding of theenvironment needs strict protection and other areas can not be polluted. Afterthe silicon anti fouling paint film is formed, the surface is very smooth, nothighly viscous and it is difficult to blend with other paint. Once falling downto the other paint surface, it must be completely removed or it should notcarry out the repainting. So it is necessary to protect the surface of theother painting carefully and thoroughly. The shelter must be fully covered thepropeller with no gap.

（螺旋槳搭設(shè)防護(hù)棚照片）
（The picture of propellerbuild-up protective casing）
3.沖砂
銅質(zhì)螺旋槳沖砂時(shí)必須采用非金屬磨料。如果用金屬磨料如鋼砂沖擊銅質(zhì)螺旋槳會(huì)在銅表面上殘留，會(huì)與銅發(fā)生電偶腐蝕。銅質(zhì)螺旋槳沖砂時(shí)必須采用如棕剛玉、石英砂、石榴石等非金屬磨料。磨料盡快能采用14—16#。沖砂表面要達(dá)到粗糙度35—65微米。
3. Sand washing
Non-metal abrasive should be adopted when copperpropeller is sand washing. If such as metal abrasive is used in sand washing, itwill remain on the surface of the copper propeller, then galvanic corrosionwill occur with Cu. When the copper propeller is sand washing, such as regularfused alumina, quartz sand, garnet and other non-metallic abrasive must beused. Abrasive can be used as soon as 14 – 16#.After the process, the copperpropeller surface roughness should reach 35 – 65 um.

（ The picture of propeller surface after sand washing sand inclusion phenomenon ）
（螺旋槳沖砂后手工砂紙打磨前后對(duì)比照片）
（The picture of Screwsand washing after manual comparison before and after sanding）
沖砂后螺旋槳表面會(huì)有很多的灰塵和磨料的殘留。有機(jī)硅防污涂料系統(tǒng)對(duì)表面清潔要求很高，這些必須清除干凈。要用砂紙進(jìn)行手工打磨以除去這些不好清理的殘留。并用高壓風(fēng)進(jìn)行細(xì)致吹塵。
There will be a lot of dust and abrasive residueon the surface of the propeller after sand washing. The silicone anti foulingpainting system needs high requirements on the surface’s cleanliness, So theseresidue must be cleared. To use sandpaper polished to remove these residuesthat hard to cleaning and use high pressure air to blow away the dustcarefully.
（螺旋槳沖砂后有油污殘留照片）
（ The picture of afterthe screw sand washing oil residue ）
對(duì)于一些殘留的油漬，也要用稀釋劑清洗干凈。
Someof the remaining oil also needed to use thinner to clean.
（螺旋槳噴漆前最后一道清潔照片）
（ The picture of propellerlast cleaned before painting ）
最后對(duì)整個(gè)螺旋槳做噴漆前細(xì)致的清潔，確保所有螺旋槳表面都符合施工要求。并請(qǐng)油漆技術(shù)服務(wù)商進(jìn)行過程確認(rèn)。
Finally,the whole propeller should be cleaned carefully before painting and to ensurethat all the surface of the propeller are in line with the requirements of theconstruction and to confirm the process with paint technical service providers.

3. 噴漆。 3. Painting
第一道漆為丁醛樹脂基蝕刻底漆。主要功能就是封閉銅表面，增加與下道涂料的附著力。
The first paint is butyraldehyde resinetch primer which main function is to seal the surface of copper and increasethe adhesion with the next。

第二道漆為改性環(huán)氧漆中間漆，作為配套CMP BIOCLEAN防污體系的底漆。要提前做好預(yù)涂，并在噴涂前做好表面清潔。選用技術(shù)水平高的槍手，確保一次噴漆達(dá)到規(guī)定漆膜厚度。盡可能避免漆膜的二次修補(bǔ)。
Thesecond paint is modified epoxy intermediate paint which is used as the primerof the CMP BIOCLEAN antipollution system. It must be pre-painted in advance andkeep the surface clean. Skilled painting worker should be chosen and ensurethat the thickness of the paint film reach the required standard. Try the bestto avoid the second patch of paint film.

（The picture of painttechnology services chamber of commerce inspect the second oil film thickness）
第三道漆為有機(jī)硅防污漆，這道漆至關(guān)重要。它施工的好壞也直接影響這個(gè)涂裝質(zhì)量。要求也十分的苛刻。由于有機(jī)硅防污涂料表面光滑，機(jī)械結(jié)合力很弱。涂裝間隔就顯得尤為重要，一般的情況下油漆技術(shù)服務(wù)商都會(huì)要求在4-8小時(shí)之間就進(jìn)行復(fù)涂。只要中間漆表面固化，就可以進(jìn)行復(fù)涂以增加油漆層間化學(xué)分子鏈的結(jié)合。有機(jī)硅防污涂料，不可以和其他油漆混合。所以在進(jìn)行有機(jī)硅防污涂料施工時(shí)所用的工具，必須是全新或者是仔細(xì)清理過的。
Thethird paint is silicone antifouling paint which is the most important part inthis process. The construction quality has a direct impact on the quality ofpainting. The requirements are also very harsh. Because of the siliconeantifouling coatings with smooth surface, mechanical binding force is veryweak. So the time between the painting is important, under normalcircumstances, the paint technology service providers will required the secondpainted in 4-8 hours. As long as the middle of the paint surface curing, the secondpainting can be carried out to increase the paint layer between the chemicalmolecular chain combinations. Silicone anti fouling paint can not be mixed withother paint. So all tool used in the construction of silicone anti foulingpaint must be new or carefully cleaned up.
（滾筒和裝油漆小桶照片）

（整體噴涂前試槍照片）
（The picture of Overallspray gun before try）
噴漆槍手一定要挑選做過特涂 、有經(jīng)驗(yàn)、水平高的槍手。在噴漆過程中一定要保證高壓空氣的壓力。確保一次性噴涂成功。在正式噴涂有機(jī)硅防污漆前一定要槍手試槍。直到確認(rèn)調(diào)試好設(shè)備才能進(jìn)行噴涂作業(yè)。
Thespraying worker must select who had a special painting, a high level ofexperience. To ensure that the pressure of high pressure air in the process ofpainting and spraying success in one time .The worker must test the paintinggun before the formal spray silicone anti fouling paint.
結(jié)束語
