HPMC neHEMC dzine mabasa akafanana muzvinhu zvekuvaka. Inogona kushandiswa semuchina wekuparadzanisa, muchina wekuchengetedza mvura, muchina wekukora uye muchina wekubatanidza, nezvimwewo. Inonyanya kushandiswa mumota wesimende uye mukugadzira zvigadzirwa zvegypsum. Inoshandiswa mumota yesimende kuwedzera kunamira kwayo, kushanda kwayo, kuderedza kupwanyika, kuvandudza kupenya uye kuderera, pamwe nekuchengetedza mvura, kuderedza kurasikirwa nemvura pamusoro pekongiri, kuvandudza simba, kudzivirira kutsemuka uye kudonha kwemunyu unonyunguduka mumvura, nezvimwewo. Inoshandiswa zvakanyanya mu plaster yakagadzirwa nesimende, gypsum plaster, zvigadzirwa zvegypsum, masonry mortar, sheet caulking, muchina wekugadzira caulking, tile adhesive, self-leveling floor material, nezvimwewo. Inogona kushandiswa semuchina wekugadzira firimu, muchina wekuwedzera, muchina wekusimbisa uye muchina wekusimbisa mu emulsion coatings uye muchina wekusimbisa resin unonyunguduka mumvura, zvichipa firimu resistance yakanaka, kufanana uye kunamira, uye kuvandudza kushushikana kwepamusoro, kugadzikana kune acids uye mabhesi uye kuenderana ne pigments dzesimbi. Nekuda kwekugadzikana kwayo kwakanaka kwekuchengetera viscosity, inonyanya kukodzera semuchina wekuparadzira mu emulsified coatings. Muchidimbu, kunyange zvazvo huwandu huri muhurongwa hwacho hushoma, hunobatsira zvikuru uye hunoshandiswa zvakanyanya.
Kupisa kwegel kwe cellulose ether kunosarudza kugadzikana kwayo mukupisa mukushandiswa. Kupisa kwegel kweHPMC kunowanzova pakati pe60°C kusvika 75°C, zvichienderana nerudzi, huwandu hweboka, maitiro akasiyana ekugadzira evagadziri vakasiyana, nezvimwewo. Nekuda kwehunhu hweHEMC group, ine tembiricha yakakwira yegel, kazhinji inopfuura 80°C. Saka, kugadzikana kwayo mumamiriro ekupisa kwakanyanya kwakakwira kupfuura kweHPMC. Mukuita, pasi pemamiriro ekuvaka anopisa zvikuru muzhizha, kuchengetwa kwemvura kweHEMC mumota yakasanganiswa yakanyorova ine viscosity imwechete uye dosing kune mukana wakakura kupfuura HPMC.
Cellulose ether inonyanya kushandiswa muindasitiri yekuvaka muChina ichiri HPMC, sezvo iine mhando dzakawanda uye mitengo yakaderera, uye inogona kusarudzwa zvakasununguka nemutengo wakazara. Nekuvandudzwa kwemusika wekuvaka wemuno, kunyanya kuwedzera kwekuvaka nemashini uye kuvandudzwa kwezvinodiwa zvemhando yekuvaka, kushandiswa kweHPMC mumunda wekuvaka kucharamba kuchiwedzera.
