HPMC neHEMC vane mabasa akafanana mukuvaka zvinhu.Inogona kushandiswa se dispersant, water retention agent, thickening agent uye binder, etc. Inonyanya kushandiswa mumatope esimende uye kuumbwa kwezvigadzirwa zvegypsum.Inoshandiswa musimende dhaka kuti iwedzere kunamatira kwayo, kushanda, kuderedza kubhururuka, kunatsiridza viscosity uye shrinkage, pamwe nekuchengetedza mvura, kuderedza kurasikirwa kwemvura pane kongiri, kuvandudza simba, kudzivirira kuputika uye mamiriro ekunze emunyu anonyungudika nemvura, nezvimwe. Inoshandiswa zvakanyanya musimende-based plaster, gypsum plaster, gypsum products, masonry mortar, sheet caulking, caulking agent, tile adhesive, self-leveling floor material, etc. Inogona kushandiswa sefirimu-forming agent, thickener, emulsifier uye stabilizer mu emulsion coatings uye mvura-soluble resin coatings, kupa firimu rakanaka abrasion kuramba, kufanana uye adhesion, uye kunatsiridza tension pamusoro, kugadzikana kune acids uye zvigadziko uye kuenderana nesimbi pigments.Nekuda kweiyo yakanaka viscosity yekuchengetedza kugadzikana, inonyanya kukodzera seanoparadzira mune emulsified coatings.Mune izwi, kunyangwe huwandu huri muhurongwa hudiki, hunobatsira uye hunoshandiswa zvakanyanya.
Iyo tembiricha yegel ye cellulose ether inosarudza kugadzikana kwayo kwekupisa mumashandisirwo.kupisa kwegel kweHPMC kunowanzobva ku60 ° C kusvika ku75 ° C, zvichienderana nemhando, zvinyorwa zveboka, maitiro akasiyana-siyana ekugadzirwa kwevagadziri vakasiyana-siyana, nezvimwewo Pamusana pehutano hweboka reHEMC, ine gel yakakwirira yekushisa, kazhinji pamusoro. 80°C.Nokudaro, kugadzikana kwayo pasi pemamiriro ekushisa kwepamusoro kune yakakwirira kudarika yeHPMC.Mukuita, pasi penzvimbo inopisa kwazvo yekuvaka muzhizha, kuchengetwa kwemvura kweHEMC mumvura yakasanganiswa dhaka ine viscosity yakafanana uye dosing ine mukana wakakura kupfuura HPMC.
Iyo mainstream cellulose ether muindasitiri yekuvaka yeChina ichiri kunyanya HPMC, sezvo iine marudzi mazhinji nemitengo yakaderera, uye inogona kusarudzwa zvakasununguka pamutengo wakakwana.Nekuvandudzwa kwemusika wekuvaka wepamba, kunyanya kuwedzera kwekuvaka kwemakanika uye kuvandudzwa kwezvinodiwa zvemhando yekuvaka, kushandiswa kweHPMC mumunda wekuvaka kucharamba kuchiwedzera.
