Although the putty rubber powder and HPMC powder is used in the production of raw materials, but there are certain differences between the specific putty rubber powder and HPMC what are the differences between, Zhicheng cellulose Co., LTD., will summarize several years of development experience, a detailed explanation to the users, help users of putty powder and HPMC have a more clear understanding and awareness.
1, putty rubber powder is a kind of mixture, components have several kinds, and according to different manufacturer formula is not the same, the difference is very big also.Is used to increase the putty adhesion and construction, the performance of the inside contain a CMC and HPMC, part or contain starch, etc.
2, putty rubber powder, scope of application: application range is very wide, can be in building putty for adhesives, thickening agent, leveling agent, film former, prevent enzyme agent, etc.;Dosage is small, and there's no need to add any other additives (other products).For example: use this product as additives to make the external walls of putty powder, mix with water can be directly used when use, easy and convenient construction, green environmental protection;Shaved the wall never turn yellow, strong as steel, general collision and moment no traces, smooth and bright, feel like porcelain like jade exquisite intoxicating, fire resistant enzymes, breathable moisture, acid and alkali resistance, resistance to dirt stain resistant, resistance to wash brush, waterproof prevent bask in, not to take off not crack, long service life.
3 is a kind of ionic cellulose, carboxymethyl cellulose CMC, cheap, wide application, can be directly used in ordinary putty, but cannot do waterproof putty, can't come with ash calcium use, will react into tofu.
4, hydroxypropyl methyl cellulose HPMC is a kind of non-ionic cellulose, nature is stable, can do all kinds of high-grade putty, unresponsive and ash calcium.
