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 kwayo, kuderedza flocculation, kunatsiridza viscosity uye shrinkage, pamwe nekuchengetedza mvura, kuderedza kurasikirwa kwemvura pamusoro pekongiri yepamusoro, kuvandudza simba, kudzivirira kuputika uye mamiriro ekunze emunyu unonyunguduka wemvura, etc. Inoshandiswa zvakanyanya mu simenti-based plaster, gypsum plaster, gyulking sheet moruls, gypsum plaster, gyulking sheet, cas, gypsum, gypsum plaster, gypsum plaster adhesive, self-leveling floor material, etc. Inogona kushandiswa sefirimu-kuumba mumiririri, thickener, emulsifier uye stabilizer mu emulsion coatings uye mvura-soluble resin coatings, kupa firimu zvakanaka abrasion kuramba, kufanana uye adhesion, uye kunatsiridza pamusoro tension, kugadzikana kune acids uye zvigadziko uye kuenderana nesimbi yenguruve. 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. gel tembiricha yeHPMC inowanzobva ku60 ° C kusvika 75 ° C, zvichienderana nerudzi, zvinyorwa zveboka, maitiro akasiyana-siyana ekugadzirwa kwevagadziri vakasiyana-siyana, nezvimwewo Pamusana pemaitiro eboka reHEMC, ine gel rinopisa, rinowanzopfuura 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.
