The performance and quality of putty powder for exterior wall depends entirely on the performance and quality of various raw materials selected in putty. The raw materials used are stable in performance and good in quality. The performance and quality of products are good. There will be no major problems in production, whether manual or mechanical, as long as they are mixed evenly. To ensure the quality of putty powder for exterior wall. In terms of engineering quality assurance, Bainianda believes that the main thing is to pay attention to the treatment of grass-roots and grass-roots interfaces.
The treatment of grass-roots and grass-roots interface has the following contents:
1. 基層的穩(wěn)定性麻顶。施工前要對(duì)基層進(jìn)行仔細(xì)檢查和確認(rèn),檢查基層的平整度冯勉、強(qiáng)度澈蚌、基層吸水率摹芙,基層有無粉化、疏松宛瞄、返堿等現(xiàn)象浮禾,有無明顯裂紋、裂縫(可用往墻上澆水的方法來檢查)份汗,基層是否已經(jīng)穩(wěn)定盈电。如基層達(dá)不到外墻膩?zhàn)臃鄣氖┕ひ螅瑧?yīng)先做相應(yīng)的技術(shù)處理伤刑,如基層符合外墻膩?zhàn)拥氖┕ひ筇娇欤憧梢赃M(jìn)行外墻膩?zhàn)臃凼┕ぁ?/div>
1. Stability of grass-roots units. Before construction, we should carefully check and confirm the grass-roots, check the smoothness, strength, water absorption of the grass-roots, whether the grass-roots is pulverized, loose, alkali return and other phenomena, whether there are obvious cracks, cracks (can be checked by watering the wall), whether the grass-roots is stable. If the base can not meet the construction requirements of putty powder for external wall, corresponding technical treatment should be done first. If the base meets the construction requirements of putty powder for external wall, putty powder for external wall can be constructed.
2. 基層的強(qiáng)度必須大于外墻膩?zhàn)拥膹?qiáng)度。按材料的粘結(jié)理論與實(shí)踐入撇,如果墻基層的強(qiáng)度小于外墻膩?zhàn)诱ズ鈮δ佔(zhàn)尤菀壮霈F(xiàn)“拔根”、空鼓晤裆、脫落現(xiàn)象咱漱。如基層強(qiáng)度大于外墻膩?zhàn)臃鄣膹?qiáng)度,則不會(huì)出現(xiàn)這些問題停间。
2. The strength of base must be greater than that of putty. According to the bonding theory and practice of materials, if the strength of the wall base is less than that of the external wall putty, the external wall putty is prone to "pull out", "empty drum" and "fall off". If the strength of the base is greater than that of the putty powder, these problems will not arise.

3. 對(duì)界面的嚴(yán)格處理温履。先清除浮灰、油污(包括脫模劑)叙棚,填刮基層的裂縫亥护,剔出鼓包,如基層有明顯不平的地方粗排,先用抗裂砂漿找平绎彪。如基層已特別干燥、吸水性很強(qiáng)兽赁,環(huán)境氣候也很干燥衣陶,就會(huì)影響到外墻膩?zhàn)优c基層的粘附力及強(qiáng)度,因此闸氮,建議施工前剪况,可用水先澆濕墻基層后,再進(jìn)行外墻膩?zhàn)臃鄣氖┕て芽纾绻麠l件許可译断,施工后2-3天,可噴水養(yǎng)護(hù)1-2次或悲,防裂效果和強(qiáng)度會(huì)更好孙咪。
3. Strict treatment of interface. Firstly, remove floating ash and oil (including release agent), fill and scrape cracks in the base, and remove bulges. If there are obvious unevenness in the base, first use anti-cracking mortar to leveling. If the base is especially dry, absorbable, and the environment and climate are dry, it will affect the adhesion and strength of the putty on the outer wall and the base. Therefore, it is suggested that before construction, water can be used to pour wet the base of the wall first, then to carry out the construction of putty powder on the outer wall. If conditions permit, 2-3 days after construction, water can be sprayed to maintain 1-2 times and prevent cracking. The effect and intensity will be better.
