What kind of fine work does industrial epoxy floor need to be checked before construction? The quality of the face material before coating is checked so as to design reasonable painting plan and adopt some quality control actions. Usually the items to be checked are as follows: 1. Ground smoothness: checking with 2-meter ruler, recording the void value, and checking the ground. Symbols are applied at high places to focus on grinding and to repair mud at low locations.
2. Inspection of moisture content of base material: It is necessary to know how long concrete has been maintained from customers, there is no construction waterproof layer at the bottom, and the climate condition during the maintenance period. Generally speaking, the 15-day maintenance period for upper buildings in good weather and good ventilation in Xia Dynasty is not bad. In winter, the maintenance period in water season should be longer. Usually, it takes about one month to adopt coagulation before construction. It is necessary to measure the moisture content of the base material by soil moisture meter. The following rules should be adopted for measuring points: A, bottom floor (first floor); B, near doors and windows or external walls; C, one-sided where water has been dipped after the completion of concrete casting, besides D, downspout and drainage ditch. If there is no measuring instrument, it is also useful to adopt film covering method, and the main points are as follows. The film must be leak free and tightly sealed.
3. Strength inspection of concrete: First of all, it is necessary to inspect whether concrete has sand-raising signs orally, one-sided empty drum signs, and where there are reinforcing steel materials on the ground (if not paying attention to damage machinery when mechanical polishing), and then mark and record them one by one. When handling concrete with very poor strength, special attention should be paid to it, so that ground polishing is not very useful, and the ground polishing is not very useful. It is very important to vacuum through the top before painting. After vacuum cleaning, solventless beech is used to make the bottom, even though it is immersed in the long run, to anchor the concrete after reaction solidification. 四、其他方面的查验:因环氧树脂地坪施工需求清洁闭塞的涂装境遇,任何每个细活的疏忽都或许变成返工或欠缺,变成亏损,所以在入场施工前需查验下面方面:A、门窗可否已完整,屋面、水管等可否有漏水隐患;B、照明、泄电等设施可否完备,如需自备,应策划好,C.拟施工时期的气候境况.
4. Examination of other aspects: because of the situation of clean and blocked coating for epoxy floor construction, any careless negligence may turn into rework or deficiency and become loss. Therefore, before entering the construction site, the following aspects should be checked: whether the doors and windows are complete, whether the roof, water pipe, etc. have potential leakage hazards; B, lighting, electricity leakage, etc. Whether it can be completed or not, if necessary, we should plan the climate of C. during construction.
