一、成膜厚度检查:
Film thickness inspection:
应采用针穿刺法每100平米刺三个点,用尺测量其高度,取其平均值,成膜厚度应大于2毫米。穿刺时应用彩笔做标记、以便修补。
Needle puncture method should be used every 100 square meters of three points, the measurement of its height, the average value of the film, the film thickness should be greater than 2 mm. Application of puncture marks, to repair the crayons.
二、断裂延长率检查:
Two, elongation at break:
在屋顶防水施工中,监理人员可到施工现场将搅拌好的料,分多次涂刷在平整的玻璃板上(玻璃板应先打蜡),成膜厚度1.2-1.5毫米,放置7天后,在1%的碱水中浸泡7天,然后在50℃土2℃烘箱中烘24小时,做哑铃型拉伸实验,要求延长保持率达到80%(无处理为200%)。如达不到标准,说明在施工中乳液掺加比例不足。
In waterproof construction, construction site supervision personnel to mix the material, brush in many flat on the glass plate (glass plate should first wax film thickness of 1.2), 1.5 mm, after 7 days, 7 days immersion in 1% salt water, then at 50 degrees 2 degrees oven in soil bake for 24 hours, do dumbbell tensile test requirements extension holding rate reached 80% (control 200%). If not up to the standard, the proportion of the emulsion in the construction is not enough.
三、耐水性检查:
Three, water resistance inspection:
将涂料分多次涂刷在水泥块上,成膜厚度1.2-1.5毫米,放置7天,放入1%碱水中浸泡7天,不分层,不空鼓为合格。
Paint brush in many cement blocks, film thickness of 1.2-1.5 mm, placed for 7 days in 7 days, 1% alkali water immersion is not stratified, no hollowness is qualified.
四、不透水性检查:
Four, check the water:
在有条件下,应用仪器检测,其方法是将涂料按比例配好,分多次涂刷在玻璃板上(玻璃板先打蜡),厚度为1.5毫米,静放7天,然后放入烘箱内50℃±2℃烘24小时,掏出后放置3小时,做不透水实验,不透水性为0.3MPa。保持30分钟无渗漏为合格。
In some conditions, application of instrument detection, the method is that the paint in proportion, brush in many glass (glass plate wax), thickness of 1.5 mm, quiet place for 7 days, and then put into the oven bake 50 - 2 Deg. C for 24 hours, took place after 3 hours, do not permeable experiments, impervious to 0.3MPa. To maintain 30 minutes without leakage for qualified.
若条件不具备,可用目测法检查屋顶防水结果,方法是将涂料分4—6次涂刷到无纺布上,干透后(约24h)成膜厚度为1.2-1.5毫米,做成圆盒子外形吊空,但不得留有死角,再将1%碱水加人盒内,24h无渗漏为合格。
If the conditions are not available, visual inspection method waterproof effect, method is to paint 4 - 6 times coating to the non-woven cloth, dry (about 24h) film thickness of 1.2-1.5 mm, made of round box shape hanging space, but must not be left dead, then the 1% alkaline into the box, 24h infiltration qualified leakage.
五、粘结力检查:
Five, bond strength check:
聚合物屋顶防水砂浆,可直接成形“8”字模,24小时后出模。放人水中浸泡6天,室内温度25℃±2℃干养护21天,做粘坚固验。G型屋顶防水砂浆,灰:水:胶=1:0.11:0.14,屋顶防水砂浆为2.3MPa。
Polymer waterproof mortar can be directly formed "8" font, 24 hours after the die. Put people in the water for 6 days, the indoor temperature of 25 degrees Celsius 2 degrees C dry curing for 21 days, doing the bonding experiment. G type waterproof mortar, ash: water: plastic =1:0.11:0.14, waterproof mortar for 2.3MPa.
将聚合物屋顶防水涂料和成芝麻酱状,将和好的涂料涂到两个半“8”字砂浆块上,放置7天做粘坚固验,配比(高弹),粉:胶=1:1.4;(中弹),粉:胶=1:0.8-1。聚合物屋顶防水涂料为0.5MPa,大于等于粘结指标为合格。
The polymer waterproof coating and tahini, will be a good coating to 2.5 "8" mortar block, place 7 days for bonding experiments, the ratio of (Gao Dan), rubber powder: =1:1.4; (shot), rubber powder: =1:0.8-1. Polymer waterproofing paint for 0.5MPa, greater than or equal to the bond index for qualified.
六、低温柔度检查:
Six, low temperature flexibility tests:
在玻璃板上打蜡,将施工现场搅拌好的涂料分多次涂刷在玻璃板上,成膜厚度1.2-1.5毫米,干透后从玻璃板上取下,放置室内(25℃±2℃)7天(SEO关键词优化),然后剪下长120-150毫米,宽20毫米的条状,将冰箱温度调至-25℃,将试片放入冰箱内30分钟,用直径10毫米圆棒正反各缠绕一次,无裂纹为合格。如有裂纹说明乳液低温柔度不够。
Wax on the glass plate, the construction site mixing good paint brush in many glass plate, film thickness of 1.2-1.5 mm, dried from the glass plate removed, placed indoors (25 - 2 Deg. C) for 7 days, then cut 120-150 mm long, 20 mm wide strip of refrigerator the temperature at -25 DEG C, the sample is placed in the refrigerator for 30 minutes, once the wound with a diameter of 10 mm round bar and no crack, qualified. If there is a crack that not enough emulsion flexibility at low temperature.
