Why does Jinan putty powder become thinner after mixing with water?

Cellulose is used as a thickener and water-retaining agent on putty. Due to the thixotropy of cellulose itself, the addition of cellulose in putty powder also leads to thixotropy of putty after adding water. This thixotropy is caused by the destruction of the loosely bound structure of the components in the putty powder. This kind of structure is generated when it is still and is disassembled under the action of stress. That is to say, the viscosity decreases under stirring and recovers at rest.

In this case, the viscosity of cellulose used is generally too high. Some factories use 200000 yuan to make putty. The putty made in this way has a heavy feeling when scraping because of its high viscosity. The recommended amount of internal wall putty is 3-5 kg, and the viscosity is 8-100000.

冬天和夏天用同樣的粘度纖維素做出的膩?zhàn)雍蜕皾{為什么感覺粘度不一樣？

Why do putty and mortar made of cellulose with the same viscosity feel different in winter and summer?

由于產(chǎn)品的熱凝膠性避掩，決定了產(chǎn)品的粘度隨溫度的升高會(huì)逐漸降低的紊徊，當(dāng)溫度超過產(chǎn)品凝膠溫度時(shí)，產(chǎn)品將會(huì)從水中析出的鬼雀，從而失去粘度顷窒。夏天室溫一般都到30度以上了，這和冬天的溫度相差已經(jīng)很多了源哩，所以感覺粘度要低的蹋肮。

Due to the thermal gelling property of the product, the viscosity of the product will gradually decrease with the increase of temperature. When the temperature exceeds the gel temperature of the product, the product will precipitate from the water, thus losing the viscosity. The room temperature in summer is generally above 30 degrees, which is much different from the temperature in winter, so I feel that the viscosity is lower.

建議夏天在產(chǎn)品應(yīng)用時(shí)盡量選擇產(chǎn)品粘度高一個(gè)規(guī)格的產(chǎn)品，或是增加纖維素的用量璧疗，再有就是選擇產(chǎn)品凝膠溫度高的產(chǎn)品坯辩，盡量選用MK牌號(hào)的產(chǎn)品馁龟，這個(gè)產(chǎn)品的凝膠溫度一般在70度以上的。夏天盡量不要用甲基纖維素漆魔，其凝膠溫度在55度左右坷檩，溫度稍微偏高，其粘度就會(huì)受到很大的影響的改抡。

It is recommended to select the product with a higher viscosity or increase the amount of cellulose in summer, and then select the product with a higher gel temperature, and try to select the product with MK brand. The gel temperature of this product is generally above 70 degrees. Try not to use methyl cellulose in summer. The temperature of its gel is about 55 degrees. If the temperature is slightly higher, its viscosity will be greatly affected.
