一、成膜厚度檢查:
Film thickness inspection:
應(yīng)采用針穿刺法每100平米刺三個(gè)點(diǎn),用尺測(cè)量其高度,取其平均值,成膜厚度應(yīng)大于2毫米。穿刺時(shí)應(yīng)用彩筆做標(biāo)記、以便修補(bǔ)。
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、斷裂延長(zhǎng)率檢查:
Two, elongation at break:
在屋頂防水施工中,監(jiān)理人員可到施工現(xiàn)場(chǎng)將攪拌好的料,分多次涂刷在平整的玻璃板上(玻璃板應(yīng)先打蠟),成膜厚度1.2-1.5毫米,放置7天后,在1%的堿水中浸泡7天,然后在50℃土2℃烘箱中烘24小時(shí),做啞鈴型拉伸實(shí)驗(yàn),要求延長(zhǎng)保持率達(dá)到80%(無(wú)處理為200%)。如達(dá)不到標(biāo)準(zhǔn),說(shuō)明在施工中乳液摻加比例不足。
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、耐水性檢查:
Three, water resistance inspection:
將涂料分多次涂刷在水泥塊上,成膜厚度1.2-1.5毫米,放置7天,放入1%堿水中浸泡7天,不分層,不空鼓為合格。
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、不透水性檢查:
Four, check the water:
在有條件下,應(yīng)用儀器檢測(cè),其方法是將涂料按比例配好,分多次涂刷在玻璃板上(玻璃板先打蠟),厚度為1.5毫米,靜放7天,然后放入烘箱內(nèi)50℃±2℃烘24小時(shí),掏出后放置3小時(shí),做不透水實(shí)驗(yàn),不透水性為0.3MPa。保持30分鐘無(wú)滲漏為合格。
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.
若條件不具備,可用目測(cè)法檢查屋頂防水結(jié)果,方法是將涂料分4—6次涂刷到無(wú)紡布上,干透后(約24h)成膜厚度為1.2-1.5毫米,做成圓盒子外形吊空,但不得留有死角,再將1%堿水加人盒內(nèi),24h無(wú)滲漏為合格。
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、粘結(jié)力檢查:
Five, bond strength check:
聚合物屋頂防水砂漿,可直接成形“8”字模,24小時(shí)后出模。放人水中浸泡6天,室內(nèi)溫度25℃±2℃干養(yǎng)護(hù)21天,做粘堅(jiān)固驗(yàn)。G型屋頂防水砂漿,灰:水:膠=1:0.11:0.14,屋頂防水砂漿為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.
將聚合物屋頂防水涂料和成芝麻醬狀,將和好的涂料涂到兩個(gè)半“8”字砂漿塊上,放置7天做粘堅(jiān)固驗(yàn),配比(高彈),粉:膠=1:1.4;(中彈),粉:膠=1:0.8-1。聚合物屋頂防水涂料為0.5MPa,大于等于粘結(jié)指標(biāo)為合格。
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、低溫柔度檢查:
Six, low temperature flexibility tests:
在玻璃板上打蠟,將施工現(xiàn)場(chǎng)攪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,干透后從玻璃板上取下,放置室內(nèi)(25℃±2℃)7天(SEO關(guān)鍵詞優(yōu)化),然后剪下長(zhǎng)120-150毫米,寬20毫米的條狀,將冰箱溫度調(diào)至-25℃,將試片放入冰箱內(nèi)30分鐘,用直徑10毫米圓棒正反各纏繞一次,無(wú)裂紋為合格。如有裂紋說(shuō)明乳液低溫柔度不夠。
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.
