HPMC manufacturer-Is Stirring and Thinning in Putty Powder Influence the Quality of HPMC Cellulose?
1. The root cause of this problem is the hpmc cellulose added to the putty powder.
When the putty powder is produced and used, various problems will occur. After the putty powder is mixed with water and stirred with an electric drill, the more the putty is stirred, the thinner it will appear, and the water separation phenomenon will be serious. The reason for this phenomenon is the hpmc fiber. If the viscosity of the element is not suitable, the viscosity is too low, and the suspension effect is not enough, the phenomenon of water separation will be serious at this time, and the effect of uniform suspension cannot be reflected.
2. The hpmc cellulose water-retaining agent added to the putty powder has a very good water-retaining effect.
When the putty is dissolved in water, it locks a large amount of water. At this time, a lot of water is flocculated into water groups. When stirring, a lot of water is separated, so the problem of more and more dilution occurs. When such a problem is encountered, the addition amount of hpmc cellulose can be appropriately reduced or the added water content can be reduced.
3. The structure of hpmc cellulose has a certain relationship.
It has thixotropy, so after adding hpmc cellulose, the whole coating has a certain thixotropy, so when the putty is rapidly stirred, its overall structure is dispersed, There is a phenomenon of more and more thinning, but when standing still, it slowly recovers.
