The base layer is dry, with high water absorption rate, and the base layer is loose with low strength - the loose wall absorbs moisture from the putty; There is floating ash on the wall - floating ash is mixed with putty to absorb moisture in the putty
收刮時(shí)間長借倘,反復(fù)收光
Long scraping time, repeated polishing
產(chǎn)品本身的保水性不足
Insufficient water retention of the product itself
2. Jinan putty powder caking
原因分析

1、運(yùn)輸途中受潮
1. Moisture during transportation
2枣象、倉儲(chǔ)受潮
2. Moisture in storage
處理方案
Processing plan
1屠剥、加強(qiáng)遮蔽
1. Strengthen masking
2、提升存儲(chǔ)條件
2. Improve storage conditions
3舶舅、可使用時(shí)間短
3. Short usable time
標(biāo)準(zhǔn)可使用時(shí)間1.5h莫彩,主要指桶內(nèi)干的過快
The standard usable time is 1.5 hours, mainly referring to the rapid drying in the barrel
原因分析:
Reason analysis:
(1)夏季水泥水化速度加快,會(huì)大大縮短初凝時(shí)間和終凝時(shí)間
(1) The accelerated hydration rate of cement in summer will greatly shorten the initial and final setting times
(2)石膏產(chǎn)品奸闽,石膏原材料的波動(dòng)導(dǎo)致了產(chǎn)品的初琼牧、終凝時(shí)間發(fā)生變化。使用過的桶沒有清洗干凈繼續(xù)使用
(2) The fluctuation of gypsum raw materials in gypsum products leads to changes in the initial and final setting times of the products. If the used bucket is not cleaned thoroughly, continue to use it
4哀卫、攪拌后呈現(xiàn)豆腐渣狀
4. After stirring, it appears as tofu residue

Mixing putty powder from different systems together
原因分析:

1. During construction, two types of putty powder are used simultaneously, causing reactions with adhesive substances, displacement, and denaturation, resulting in no water retention effect and causing tofu residue phenomenon
2带斑、攪拌時(shí)桶未清理干凈
2. The bucket was not cleaned thoroughly during mixing
3鼓寺、生產(chǎn)過程中兩種體系的產(chǎn)品混在了一起
3. The products of the two systems were mixed together during the production process

基層原因且未使用配套體系產(chǎn)品勋磕,如粗底膩?zhàn)诱移郊蛹?xì)底膩?zhàn)邮展饴韬颍绗F(xiàn)澆混凝土墻界面處理敢靡。
Due to grassroots reasons and without the use of supporting system products, such as leveling with coarse bottom putty and polishing with fine bottom putty, such as interface treatment of cast-in-place concrete walls.

1. The majority of putty powder bubbles are caused by the base layer, so it is particularly important to treat the base layer.
2鲫础、控制施工,膩?zhàn)臃矍屑蓴嚢柽^稀或者批刮過厚
2. Control construction, avoid mixing putty powder too thinly or scraping it too thick in batches
3奥徒、如膩?zhàn)优涮仔圆患鸭德眩瑒t進(jìn)行配方升級(jí)。
3. If the matching performance of the putty is poor, the formula should be upgraded.
