胶衣的喷涂和涂刷
The spraying and brushing coating
为了改善和美化玻璃钢制品的表面状态,提高产品的价值,并保证内层玻璃钢不受侵蚀,延长制品使用寿命,我们一般是将制品的工作表面做成一层加有颜料糊(色浆)的、树脂含量很高的胶层,它可以是纯树脂,亦可用表面毡增强。这层胶层称之为胶衣层(也称为表面层或装饰层)。胶衣层制作质量的好坏,直接影响制品的外在质量以及耐候性、耐水性和耐化学介质侵蚀性等,故在胶衣层喷涂或涂刷时应注意以下几点:
In order to improve and beautify the surface state of glass steel
products, improve product value, and the inner glass steel from erosion,
prolong the service life of products, we will generally work surface
products into a layer with pigment paste (paste), high content of resin
adhesive, it is also pure resin. Available surface mat reinforced. The
adhesive layer is called gel coat (also known as the surface layer or
decorative layer). Production quality of gel coat will directly affect
the product quality and the external resistance, water resistance and
chemical resistance of erosion, so in the gel coat spraying or brushing
should pay attention to the following points:
(1)配置胶衣树脂时,要充分混合,特别是使用颜料糊时,若混合不均匀,会使制品表面出现斑点和条纹,这不仅影响外观,而且还会降低它物理性能。为此应尽可能采用机械搅拌进行混合,且最好用不产生漩涡的混合机,以避免混进空气。
(1) the configuration of gel coat resin, to fully mix, especially
the use of pigment paste, if uneven mixing, will make the products
appear on the surface of spots and stripes, which not only affects the
appearance, but also reduce its physical properties. This should be
possible by mechanical stirring and mixing, the best mixing machine does
not produce a whirlpool, to avoid entering into the air.
(2)胶衣可以用毛刷或专用喷枪来喷涂。喷涂时应补加5~7﹪的苯乙烯以调节树脂的粘度及补充喷涂过程中挥发损失的苯乙烯。
(2) gel can brush or spray gun to spray. When spraying should be
volatilization viscosity and added spraying process adding 5~7% styrene
resin of styrene to adjust.
(3)胶衣层的厚度应精确控制在0.3~O.5mm之间,通常以单位面积所用的胶衣质量来控制,即胶衣的用量为350~550g/㎡,这样便能达到上述要求的厚度。
(3) coating layer thickness should be accurately controlled at
0.3~O.5mm, usually in the unit area are used to control the quality of
gel, the gel dosage is 350~550g/ square meters, so that they can achieve
the required thickness.
