防水涂料涂膜模具使用方法:
★在試樣制備前,所取樣品及所用儀器均在標(biāo)準(zhǔn)條件下(溫度23℃±2℃;相對濕度45%~70%)放置24h。
★為了便于脫模,在基板(玻璃板)上和??蛏峡捎霉栌突蚴炞髅撃┻M(jìn)行表面處理。
★在標(biāo)準(zhǔn)條件下,將靜置后的樣品攪拌均勻,若樣品是雙組分涂料,則按產(chǎn)品的配合比稱取所需的主劑和固化劑,把兩組分混合后充分?jǐn)嚢?min。
★在不混入氣泡的情況下將攪拌好的防水涂料立即傾倒于本涂膜模具中進(jìn)行涂覆。
★樣品應(yīng)分次涂覆,A后一次用涂刮棒將其表面刮平,并在標(biāo)準(zhǔn)條件下養(yǎng)護(hù)168h。
★檢查涂膜外觀,表面應(yīng)無明顯氣泡、光滑且平整。
★起膜后,用切片機(jī)切割涂膜,制得符合GB/T 528所規(guī)定的啞鈴狀Ⅰ型試樣,以備不同拉伸試驗(yàn)之用。
How to use the coating mold frame:
★Before the preparation of the samples,the samples taken and the instruments used were placed under standard conditions(temperature 23°C±2°C;relative humidity 45%~70%)for 24 hours.
★In order to facilitate demolding,silicone oil or paraffin can be used as a mold release agent on the substrate(glass plate)and mold frame for surface treatment.
★Under standard conditions,stir the sample after standing evenly.If the sample is a two-component coating,weigh the required main agent and curing agent according to the product mix ratio,and mix the two components for 5 minutes.
★Pour the stirred waterproof paint into this coating film mold for coating immediately without mixing air bubbles.
★The sample should be coated in several steps.After A,the surface should be scraped flat with a coating bar and cured under standard conditions for 168h.
★Check the appearance of the coating film.The surface should be free of obvious bubbles,smooth and flat.
★After filming,use a microtome to cut the coating film to obtain dumbbell-shaped type I specimens that meet the requirements of GB/T 528 for different tensile tests.
