Optimal performance of the pressure-sensitive adhesive requires that the substrates to which these gaskets must adhere are cleaned prior to application. Chomerics has developed specific, easy-to-follow procedures for preparing the following substrates:
压敏粘结剂要获得最佳性能，要求垫片要粘贴的基体在施加粘贴前清洁干净。Chomerics 已制定了专门的、易于遵守的步骤来准备以下基体：
Phosphate-coated steel
带磷酸盐涂层钢件
Conversion-coated aluminum
转化涂层铝件
Stainless and mild steel
不锈钢和低碳钢
It is essential to follow these cleaning instructions to ensure maximum adhesion of the PSA to metal substrates. Failure to comply with the appropriate cleaning process could result in poor adhesion.
遵守此处清洁规程对于保证PSA与金属基体具有最大粘结力非常重要。不遵守相关清洁程序会导致粘结不良。
Proper safety precautions should be followed to protect the operator.
应遵守正确的安全注意事项以保护操作人员。
SURFACE PREPARATION OF CONVERSION-COATED ALUMINUM AND PHOSPHATE-COATED STEEL
转化涂层铝制品和磷酸盐涂层钢制品表面制备
1. Using a clean, lint-free applicator, moistened with MEK, acetone or IPA, wash the surface until all traces of contamination have been removed.
使用干净的、无棉屑擦布蘸丁酮、丙酮或异丙醇清洗表面，直到所有污染物痕迹都已去除。
华译网上海翻译公司曾经翻译过大量有关不锈钢和低碳钢资料文件，Beijing Chinese Subtitling Translation Service Agency has translated many technical documents about Stainless and mild steel.
2. Clean the surface until the cotton applicator shows no discoloration.
对表面进行清洁直到棉擦布不变色。
3. If discoloration still exists, continue washing, changing the cotton applicator each time, until clean. Note: With phosphate coatings, it is very hard to remove all discoloration from the surface so it is up to the operator to determine the cleanliness of the surface prior to bonding. Typically, cleaning the surface 3 times is required.
仍然变色，继续清洗，每次更换棉擦布，直到干净为止。注意：对于磷酸盐涂层，从表面去除所有变色非常困难，所以由操作员确定粘结前的表面是否干净。通常，需要对表面清洁3遍。
4. Allow the substrate to dry completely at room temperature. After the cleaning sequence is complete, do not touch the substrate with bare hands.
等基体在室温下完全干燥。清洁步骤完成后，不要用裸手接触基体。
If the cleaned surfaces do not have the PSA applied within an 8 hour period, rewash using the above process.
如果经清洁的表面8小时期间内没有施加PSA，则使用上述过程重新清洗。
SURFACE PREPARATION OF STAINLESS OR MILD STEEL
不锈钢或低碳钢制品表面制备
1. Using a 3M Scotch-Brite? pad or equivalent, lightly abrade the steel surface.
使用 3M Scotch-Brite? 擦拭布或等同产品，轻轻擦磨钢件表面。
2. Blow the dust residue off of the steel surface with oil-free filtered air.
使用无油过滤空气从钢件表面吹走剩余灰尘。
3. Follow Steps 1 through 5 from the previous section to complete the surface preparation.
遵循上一部分中的步骤1到步骤5，完成表面制备。
GASKET INSTALLATION PROCEDURE
垫片安装程序
1. Cut gasket material to specific lengths per drawing. If gasket is one piece, such as a four-corner spliced gasket, pre-fit the assembly to ensure fit and location.
根据图纸将垫片材料切至规定长度。如果垫片为一件型，诸如一个四角拼接垫片，对组合件进行预配保证其配合和位置。
2. Remove a portion of the gasket liner and position the gasket. Press firmly against the gasket to tack in place. Continue pressing along the entire length of gasket until it is positioned and aligned to the mating surface.
剥去垫片衬层的一部分并放置垫片。紧紧按压垫片使其固定在位。继续沿垫片整个长度按压，直到其放置并与配合表面对齐。
3. Using a rubber roller, apply moderate pressure to the entire gasket to ensure complete contact between the PSA and substrate surface. Note: It is important during the rolling procedure that the operator not apply excessive pressure to the gasket. Extreme pressure will cause the gasket to elongate and creep as it relaxes, which may cause poor bonding to the substrate surface.
使用一个胶辊，在整个垫片上施加适度压力保证PSA和基体表面间完全接触。注意：在辊压步骤，操作员不要对垫片施力过度，这很重要。压力过度会导致垫片伸长并在其放松时出现折皱，可能会导致对集体表面粘结不良。 |
