1, The glue prepared is clear and transparent and does not precipitate after a long time.
2, Glue thickener is simple to use, not affected by time and temperature, non-toxic and tasteless, is a new type of environmentally friendly materials. It can completely replace the application of acrylamide in the glue and become a new generation of environmentally friendly construction glue materials.
3, Formulated glue is widely used in paper making, textile building decoration, wood bonding and other industries.
4, Glue special thickener prepared glue single batch of double flying powder, talc does not fall off powder to sand, while to cement, gypsum, putty powder and other kinds of powder compatibility, not roll skin, easy to feel.
Compared with the traditional process, the grinding and dispersion efficiency pe wax factory of the new process is increased by 1.4 times, and the grinding time is shortened by 43%. The color paste is formulated into a white paint and tested for various physical and chemical indicators. It is obviously better than the traditional formula in terms of storage stability, whiteness, and anti-yellowing. In other aspects, it is not inferior to the traditional formula. Refer to Table 2-
Changes in viscosity and thixotropy of PVC before and after storage at 12%.
Viscosity/mPa·s thixotropic value (6 revolutions/60 revolutions)
Grinding dispersion time. For example, by dispersing carbon black and Ti Oz in alkyd resin, adding 1% amino alcohol dispersant, the grinding efficiency can be increased by 3 times.
In order to obtain better coating performance, use wetting and dispersing agent in the resin polymer dispersion system containing active groups, and it is best to let the wetting and dispersing agent be adsorbed on the surface of the pigment first. For comparison, pay attention to the following points:
①The surface characteristics of the pigment. For inorganic pigments, it is necessary to understand whether it is acidic or alkaline or amphoteric.
②What is the active group of the resin, and whether the resin is acidic or alkaline.
③ Then choose the wetting and dispersing agent according to the characteristics of the pigment surface and the resin active group and pH. In other words, pay special attention to the acid-base relationship between the three.
