Precautions when using cellulose for putty powder
With the continuous strengthening of the chemical application of cellulose, products called special cellulose for putty powder are widely used to improve and enhance the properties of materials such as thermal insulation mortar masterbatch, putty powder, asphalt roads, gypsum products, etc. Its production stability and construction suitability have significant effects. The following hydroxypropyl methylcellulose manufacturers will briefly introduce the precautions when using cellulose for putty powder.
Cellulose for putty powder is mainly used as a thickener and water-retaining agent for putty powder. With the addition of special cellulose, putty powder will produce thixotropy due to cellulose after adding water. The occurrence of these thixotropy is because putty The loosely combined structure of the components in the powder is destroyed, so the more the putty powder is mixed with water, the thinner it will be. Pay attention to the control of the amount of putty powder mixed with water.
When the viscosity of the special cellulose for putty powder is too high, it is easy to cause the putty to sink during the batch scraping process. Therefore, pay attention to the addition amount of the special cellulose for putty powder. Generally, the recommended addition amount for interior wall putty is 3-5KG, and the viscosity is 8-100,000. In addition, because of the thermal gelation of cellulose, the viscosity of the putty and mortar made will gradually decrease with the increase of temperature, so the viscosity of cellulose for putty powder will be different in winter and summer. It is recommended to choose a product with a higher viscosity by 1 specification in summer, or increase the intake of cellulose, and then choose a product with a high gel temperature.
To sum up, the special cellulose for putty powder has excellent characteristics such as improved fluidity, reduced density, good air permeability, and green environmental protection.
