基層干燥，吸水率高,基層疏松、強(qiáng)度低——疏松墻體吸收膩?zhàn)又兴郑粔γ嬗懈』?mdash;—浮灰與與膩?zhàn)踊旌?，吸收膩?zhàn)又兴?/div>
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(zhǎng)，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
Cause analysis
1、運(yùn)輸途中受潮
1. Moisture during transportation
2、倉(cāng)儲(chǔ)受潮
2. Moisture in storage
處理方案
Processing plan
1、加強(qiáng)遮蔽
1. Strengthen masking
2、提升存儲(chǔ)條件
2. Improve storage conditions
3、可使用時(shí)間短
3. Short usable time
標(biāo)準(zhǔn)可使用時(shí)間1.5h，主要指桶內(nèi)干的過(guò)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，石膏原材料的波動(dòng)導(dǎo)致了產(chǎn)品的初、終凝時(shí)間發(fā)生變化。使用過(guò)的桶沒(méi)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、攪拌后呈現(xiàn)豆腐渣狀
4. After stirring, it appears as tofu residue
不同體系的膩?zhàn)臃刍旌显谝黄?/div>
Mixing putty powder from different systems together
原因分析：
Reason analysis:
1、施工中同時(shí)使用兩種膩?zhàn)臃郏鹉z黏物質(zhì)發(fā)生反應(yīng)，置換、變性導(dǎo)致無(wú)保水作用，造成豆腐渣現(xiàn)象
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、攪拌時(shí)桶未清理干凈
2. The bucket was not cleaned thoroughly during mixing
3、生產(chǎn)過(guò)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
5、濟(jì)南膩?zhàn)臃蹥馀?/div>
5. Jinan putty powder bubbles
膩?zhàn)臃凼┕ぶ懈Ｒ?jiàn)的一個(gè)問(wèn)題
The most common problem in putty powder construction
原因分析：
Reason analysis:
基層原因且未使用配套體系產(chǎn)品，如粗底膩?zhàn)诱移郊蛹?xì)底膩?zhàn)邮展猓绗F(xiàn)澆混凝土墻界面處理。
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.
產(chǎn)品本身配套性不佳
Poor matching of the product itself
一次性批刮膩?zhàn)舆^(guò)厚
Excessive thickness of one-time batch putty
攪拌膩?zhàn)臃圻^(guò)稀
Mixing putty powder too thin
基層原因，溫度過(guò)高、太過(guò)于干燥
Grassroots reasons, high temperature, too dry
處理方案：
Solution:
1、膩?zhàn)臃蹥馀荻鄶?shù)是因?yàn)榛鶎釉颍虼藢?duì)基層進(jìn)行處理顯得尤為重要。
1. The majority of putty powder bubbles are caused by the base layer, so it is particularly important to treat the base layer.
2、控制施工，膩?zhàn)臃矍屑蓴嚢柽^(guò)稀或者批刮過(guò)厚
2. Control construction, avoid mixing putty powder too thinly or scraping it too thick in batches
3、如膩?zhàn)优涮仔圆患眩瑒t進(jìn)行配方升級(jí)。
3. If the matching performance of the putty is poor, the formula should be upgraded.
That's all for the common questions about putty powder. I hope it can be helpful to you. For more information, please come to our website http://www.zzmdwxsh.com Consult!
