結(jié)合力測(cè)試中英版

1、3.涂層間結(jié)合力測(cè)試The objective of this test procedure is to detect problems with adhesion at the earliest possible stage and thereby prevent potentially very large problem showing up later in the coating process.該測(cè)試的目的是通過(guò)的結(jié)合力測(cè)試盡可能早的發(fā)現(xiàn)結(jié) 合力問(wèn)題，防止今后油漆在擔(dān)保期內(nèi)發(fā)生潛在的問(wèn)題。The procedure described here is mandatory for a

2、ll class 0 Ballast and Cargo Tank Coatings. This applies not only when application is carry out at newbuilding block stage, but also during in-situ applications at either newbuilding or M&R. The test is described in detail in the Worldwide Marine Technical Bulletin Number T6 of January 1995.在此描述的工藝是

3、針對(duì)所有0級(jí)壓載艙和貨油艙內(nèi)足夠硬干的油漆，并要求強(qiáng)制執(zhí)行。此工藝不僅使用于新造船 的分段階段，而且也可使用于新造船或修船整船階段。此測(cè) 試在1995年1月的世界船舶技術(shù) T6號(hào)公告內(nèi)有詳細(xì)描述。Application of the test where & when何時(shí)何地進(jìn)行該測(cè)試Block StageYou should carry out the test after completion of the full coating system ,when the scheme has hardenedsufficiently. Two tests are required per bl

4、ock. One in an area of good ventilation, for example on the edge of the block, and one in an area where ventilation is more difficult and you would expect little air movement.分段階段：應(yīng)該在整個(gè)油漆系統(tǒng)完工并硬干后進(jìn)行該測(cè)試。每只分段應(yīng)該測(cè)兩次，一次在好的通風(fēng)區(qū)域進(jìn)行，例如分段的邊緣 處，一次在通風(fēng)稍差的地方。You should not carry out the test on stripe coated areas

5、, unless the system is a one-shot plus stripe coat applicatio.在預(yù)涂區(qū)域不應(yīng)做該測(cè)試，除非該配套為一度噴涂加上 一度預(yù)涂的施工。In-SituYou should carry out the tests after completion of the full system on both upper and bottom areas, again choosing spots with good and poor ventilation, if poosible. The tests should be carried out p

6、rior to touch up and final inspection, to allow for repair of the area damaged by the test.合攏后如可能，在油漆系統(tǒng)完工的情況下，底部和頂部進(jìn)行該測(cè)試，也是選擇通風(fēng)好和差的地方進(jìn)行。該測(cè)試應(yīng)該在補(bǔ)涂 或完工檢驗(yàn)之前進(jìn)行，以便修補(bǔ)由于測(cè)試所破壞的區(qū)域。The number of tests required depends upon the tank size. Common sense should prevail. As a guide you may try one test per 500m2, b

7、ut in large tanks over 2000m 2 you may take fewer tests.測(cè)試的次數(shù)依據(jù)艙室的大小而定。常規(guī)做法是，每 500 平方米內(nèi)一個(gè)點(diǎn)，但是在大于2000平方米的艙室內(nèi)你可以少做幾個(gè)點(diǎn)。Test EquipmentThe only equipment you will require is a sharp knife with a pointed blade.測(cè)試工具 唯一需要的工具就是帶有尖角的鋒利的小刀。Test Method測(cè)試方法You should make V cut of between 30 0-450 in the coating

8、, ensuring that the cut penetrates to the steel. See Figur 6.在漆膜上切由30度至45度的“v”形切口。 保證切口切至鋼板，見(jiàn)圖 6?？?45 度APEK、Figure 6 VcutUsing the knife at the Apex of the V cut to determine if the coats can be cleanly separated.用小刀來(lái)測(cè)試“ v”形尖角處的油漆能否被輕易的分離。Rate the adhesion level according to the pictorial guide give

9、n in figure 7.根據(jù)表7評(píng)價(jià)結(jié)合力的級(jí)別。Record the data on the appropriate form在相應(yīng)的表格內(nèi)記錄數(shù)據(jù)。You should also ensure that the test area is properly repaired, generally by sanding down and touching up, to ensure the integrity of the finished coatings.應(yīng)保證做結(jié)合力測(cè)試的區(qū)域得到正確修補(bǔ)，一般砂磨后修補(bǔ)，以確保最后施工的油漆的完整。4 Interpretation of Resul

10、tsThe test results given by the pictorial guide may vary from 0-5, as follows:0 = No adhesion. This is an adhesion failure, where no force is required to split the coatings and the backs offlakes are clean.= Very poor adhesion. Little force is required to splitthe coating and the backs of flakes are

11、 clean.= Poor adhesion. The backs of flakes are clean.= Acceptance adhesion. The backs of flakes are show bit of each coating.= Good adhesion.= Excellent adhesion. It is impossible to separate the coatings cleanly.3. 4測(cè)試結(jié)果的闡釋測(cè)試結(jié)果可以根據(jù)圖表所示分為0至5級(jí)，如下：0 =無(wú)結(jié)合力，這屬于結(jié)合失敗，在此無(wú)需外力油漆可以被剝離，而且漆片背面是干凈的。= 結(jié)合力很差。只需很小

12、外力既可以是油漆玻 璃，而且漆片背面是干凈的。=可接受結(jié)合力。漆片背面呈現(xiàn)少量的各涂層油漆。=好的結(jié)合力。=非常好的結(jié)合力。不可能去區(qū)分各涂層。The tests have to be carried out when the coating has hardened sufficiently to allow it, however, you should note that results will vary with cure and it is possible thatcoatings may tighten up with time and produce better resul

13、ts. You experience and common sense will indicate where this is the case. In cases where results are unsatisfactory, you should discuss the problem with your technical service manager and he will take appropriate action.必須在油漆已經(jīng)硬干的時(shí)候進(jìn)行該測(cè)試，如若不然， 你該標(biāo)注：根據(jù)干燥程度可能產(chǎn)生不同結(jié)果，也有可能隨 著時(shí)間推移將產(chǎn)生不同結(jié)果。你的經(jīng)驗(yàn)和常識(shí)會(huì)使你預(yù)知哪里將會(huì)發(fā)

14、生此情況。一旦測(cè)試結(jié)果不能令人滿(mǎn)意，你應(yīng) 該同你的技術(shù)服務(wù)經(jīng)理討論，他將會(huì)采取相應(yīng)的措施。ITQ 5Results give adhesion level 1, soon after the coating is hard enough to walk on, and levels 3&4 later in the cure process. What is happening? What action would you take?Answer問(wèn)題5:如果在涂層實(shí)干到可以在上面走路時(shí)進(jìn)行結(jié)合力測(cè)試的結(jié)果為1,而在固化之后的結(jié)合力測(cè)試為3和4。這是什么原因？該如何處理?答案：3.5 Recor

15、ding Test DataIt is very important that intercoat adhesion tests are properly recorded, and there art two forms used for this purpose.The Tank Coating Progress Report SystemSeeis used for in-situ coating.The Block Coating Condition Check SheetSeeis used for block stage painting.3.5測(cè)試結(jié)果的記錄正確的記錄涂層間的結(jié)合

16、力是很重要的。通常有兩種格式用于這項(xiàng)記錄。一是 “Tank Coating Progress Report System”,見(jiàn)圖 8, 用于合攏后的涂層。一是 “ Block Coating Condition Check Sheet”,見(jiàn)圖 9, 用于分段階段的涂層Apart from adhesion test results these forms bothrequire normal tank coating information on dates, ambient conditions etc. These documents have to be filled in correc

17、tly and completely for all tank coatings, but because of the liability issues it is critical and mandatory that it is done for class 0 Products.除了記錄結(jié)合力測(cè)試結(jié)果外，這兩種格式都需要記錄其 他一些常用的艙內(nèi)涂層的記錄信息，如日期，環(huán)境情況等等。這些信息必須完整正確的使用于所有艙內(nèi)涂層，而且考慮到可靠性這用于0級(jí)產(chǎn)品是很關(guān)鍵的，必須強(qiáng)制使用。To summarise Section 5.
