Hydroxypropyl methyl cellulose HPMC inonyanya kuve nemaviscosity matatu, HPMC-100000, HPMC-150000, uye HPMC-200000 viscosity.Kazhinji kutaura, hydroxypropyl methyl cellulose ine viscosity ye100,000 inowanzoshandiswa mukugadzirwa kwemukati nekunze kwemadziro putty powder.Cellulose ine viscosity ye200,000 uye inoshandiswa mukuvaka zvinhu zvakaita sedhaka rakaoma, madhaka ematombo ari nyore, madhaka ediatom, uye akafukidzwa nemadziro.Chigadzirwa chacho chine mvura yakanaka yekuchengetedza mhedzisiro, yakanaka thickening maitiro, yakagadzikana mhando uye mutengo unonzwisisika.
Hydroxypropyl methylcellulose HPMC inoshandiswa zvakanyanya muindasitiri yezvivakwa zvekuvaka.Nhamba yakawanda ye cellulose inogona kushandiswa seretarder, mvura inochengetedza mumiriri, thickener uye binder.Cellulose ether inoita basa rakakosha mune yakajairwa yakaoma-musanganiswa dhaka, yakakwirira-inoshanda kunze kwemadziro ekudzivirira dhaka, dhaka rinozvimisikidza, poda yakaoma inonamira, mataira eceramic anosunga dhaka rakaoma reupfu, chivakwa chepamusoro-chivakwa putty, kuputika-kusaputsika mukati nekunze. wall putty, nezvimwewo, isina mvura yakaoma-musanganiswa dhaka, gypsum plaster, kukwenya whitening agent, matete-layer majoini uye zvimwe zvinhu.Vane simba rakakosha pakuchengetwa kwemvura, zvinodiwa mvura, kunaka, kunonoka uye kushanda kwestucco system.Anowanzo shandiswa cellulose ethers mumunda wekuvaka anosanganisira HEC, HPMC, CMC, PAC, MHEC, nezvimwe.
Nonionic water-soluble cellulose ethers inobatsira zvivakwa zvekuvaka nekuda kwezvisungo zvekusunga, kugadzikana kwekupararira, uye kugona kuchengetedza mvura.HPMC, MC kana EHEC inoshandiswa mune yakawanda simende-yakavakirwa kana gypsum kuvaka, senge masonry dhaka, simende dhaka, simende coating, gypsum, cementitious musanganiswa uye emulsion putty, nezvimwewo, izvo zvinogona kusimudzira kupararira kwesimende kana jecha uye kuvandudza zvakanyanya. iyo adhesion , iyo inonyanya kukosha kune plaster, tile simenti uye putty.Nesimende, HEC haingori retarder chete, asiwo inochengetedza mvura.HEHPC inewo chinangwa ichi.Cellulose ethers inowanzoshandiswa pamwe chete negluconates mumatope seanokosha retarder additives.MC kana HEC uye CMC inowanzoshandiswa seyakasimba chikamu chewallpaper.Medium kana high viscosity cellulose ethers inowanzoshandiswa mumapepa anonamira uye zvinhu zvekuvaka.
Hydroxypropyl methylcellulose HPMC chigadzirwa chinosanganisa akawanda emuviri nemakemikari zvivakwa kuti ive yakasarudzika chigadzirwa chine akawanda mashandisiro.Izvo zvakasiyana-siyana zvivakwa ndezvizvi:
(1) Kuchengeta mvura: Inogona kuchengetedza hunyoro panzvimbo ine porous senge madziro simende mabhodhi nezvidhinha.
(2) Mafirimu-ekugadzira zvimiro: Inogona kuumba yakajeka, yakaoma, firimu rakapfava rine yakanakisa mafuta kuramba.
(3) Organic solubility: Ichi chigadzirwa chinonyungudika mune zvimwe organic solvents, senge ethanol/mvura, propanol/mvura, dichloroethane uye solution system inoumbwa nezvinonyungudutsa zviviri zveorganic muzvikamu zvakakodzera.
(4) Thermal gelation: Kana iyo aqueous solution yechigadzirwa ichi ichipisa, inoumba gel uye inoshanduka kuva mhinduro mushure mekutonhora.
(5) Chiitiko chepamusoro: Ipa chiitiko chepamusoro mumhinduro kuti uwane yakanaka colloidal emulsification nedziviriro, pamwe nekudzikamisa kwechikamu.
(6) Suspension agent: Hydroxypropyl methylcellulose inogona kudzivirira zvimedu zvakasimba kubva pakugadzirisa, nokudaro zvichidzivisa kuumbwa kwemvura.
(7) Protective colloid: Inogona kudzivirira madonhwe uye zvimedu kubva pakubatana kana kukora.

(9) Kunyungudika kwemvura: Ichi chigadzirwa chinogona kunyungudutswa mumvura muzvikamu zvakasiyana, uye huwandu hwayo hwepamusoro hunongogumira ne viscosity.
(10) Nonionic inertness: Ichi chigadzirwa is nonionic cellulose ether uye haisanganisi nesimbi yemunyu kana mamwe ayoni kugadzira mvura isinganyungudika.
(11) Acid-base kugadzikana: yakakodzera kushandiswa mukati me pH ye 3.0-11.0.
(12) Kusanaka uye kunhuhwirira, kusakanganiswa nemetabolism;inoshandiswa sezvinowedzera muzvokudya nemushonga, hazvina metabolized muzvokudya uye hazvipi macalorie.
Naizvozvo, hydroxypropyl methylcellulose HPMC inotora chinzvimbo chakakosha muindasitiri yekuvaka, uye green cellulose ichashandiswa zvakanyanya muindasitiri yekuvaka.Hunhu hwepamusoro, mitengo yakasarudzika uye masevhisi ari nani ndizvo zvagara zvichiteedzera cellulose yedu uye latex poda vagadziri.Zuva Remangwana rinoomerera kune bhizinesi uzivi hwe "kupona nemhando, kuvandudzwa nesainzi uye tekinoroji, musika nemukurumbira, uye kugona nemanejimendi".Yedu hydroxypropyl methylcellulose, redispersible latex powder, uye hydroxyethyl cellulose inopa zvigadzirwa zvemhando yepamusoro kune vakawanda vatengi.
