Inowanzoshandiswa cellulose ethers inosanganisira HEC, HPMC, CMC, PAC, MHEC, etc. Nonionic water-soluble cellulose ether ine cohesiveness, kupararira kugadzikana uye simba rekuchengetedza mvura, uye inowedzera inobatsira yekuvaka zvinhu.HPMC, MC kana EHEC inoshandiswa mune zvakawanda sement-based kana gypsum-based zvivakwa, senge masonry dhaka, simende dhaka, simende coating, gypsum, cementitious musanganiswa uye milky putty, nezvimwewo, izvo zvinogona kuwedzera kupararira kwesimende kana jecha uye. kunatsiridza zvakanyanya iyo Adhesion, iyo inonyanya kukosha kune plaster, tile simende uye putty.HEC inoshandiswa mu simenti, kwete chete seretarder, asiwo semugadziri wekuchengetedza mvura, uye HEHPC inoshandiswawo munyaya iyi.MC kana HEC inowanzoshandiswa pamwe chete neCMC sechikamu chakasimba cheiyo Wallpaper.Medium-viscosity kana high-viscosity cellulose ethers inowanzoshandiswa mumapuranga akanamirwa zvivakwa zvekuvaka.
Hydroxypropyl methylcelluloseHPMCinowanzoshandiswa mukugadzirwa kwemukati nekunze kwemadziro putty powder ine viscosity ye100,000 cellulose, muvhu rakaoma dhaka, diatom dhaka uye zvimwe zvigadzirwa zvekuvaka, cellulose ine viscosity ye200,000 inowanzoshandiswa, uye mukuzvienzanisa nezvimwe. yakakosha madhaka, cellulose ine viscosity ye400 inowanzoshandiswa.Viscosity cellulose, chigadzirwa ichi chine yakanaka kuchengetedza mhedzisiro, yakanaka thickening maitiro uye yakagadzikana mhando.HPMC inoshandiswa zvakanyanya muindasitiri yezvivakwa zvekuvaka uye inoshandiswa muhuwandu hukuru.Cellulose inogona kushandiswa seretarder, mvura yekuchengetedza mumiriri, thickener uye binder.Cellulose ether inoita basa rakakosha mune yakajairwa yakaoma-yakasanganiswa dhaka, yekunze madziro ekudzivirira dhaka, dhaka rinozvimisa, poda yakaoma yekupurasita, dhaka rekubatanidza dhaka, putty poda, mukati nekunze kwemadziro putty, dhaka risina mvura, majoini akatetepa, nezvimwewo ., vane simba rakakosha pakuchengetedza mvura, kudiwa kwemvura, kusimba, kunonoka uye kushanda kweiyo stucco system.
Hydroxypropyl methylcellulose HPMC zvigadzirwa zvinosanganisa akawanda emuviri nemakemikari zvivakwa kuti ive yakasarudzika chigadzirwa chine mashandisiro akawanda.Izvo zvakasiyana siyana ndezvizvi:
◆Kuchengetedzwa kwemvura: Inogona kuchengetedza hunyoro panzvimbo dzine maburi semapuranga esimende nezvidhinha.
◆Film-forming: Inogona kuumba firimu rakajeka, rakaoma uye rakapfava rine mafuta akawanda anopikisa.
◆ Organic Solubility: Chigadzirwa chacho chinonyunguduka mune mamwe organic solvents, akadai se ethanol / mvura, propanol / mvura, dichloroethane uye solution system inoumbwa nemhando mbiri dzemagetsi.
◆ Thermal gelation: Mushonga wemvura wechigadzirwa uchagadzira gel kana ichipisa, uye gel rakagadzirwa richava mhinduro zvakare mushure mekutonhora.
◆ Chiitiko chepamusoro: Ipa basa repamusoro mukugadzirisa kuti uwane emulsification inodiwa uye inodzivirira colloid, pamwe nekugadzirisa kwechikamu.
◆ Suspension: Hydroxypropyl methylcellulose inogona kudzivirira zvimedu zvakasimba kubva pakugadzirisa, nokudaro zvichidzivisa kuumbwa kwemvura.
◆Protective colloid: Inogona kudzivirira madonhwe uye zvidimbu kubva pakusungana kana kugwamba.
◆ Kunamira: Kunoshandiswa sechinamira chemavara emavara, zvigadzirwa zvefodya, uye zvigadzirwa zvemapepa, zvine mabasa akaisvonaka.
◆ Mvura Solubility: Chigadzirwa chacho chinogona kunyungudutswa mumvura muhuwandu hwakasiyana, uye huwandu hwayo hunogadziriswa hunongogumira ne viscosity.
◆ Non-ionic inertness: Chigadzirwa chacho chisingaiti-ionic cellulose ether, iyo isingabatanidzi nesimbi yemunyu kana mamwe ions kuti iite insoluble precipitates.
◆ Acid-base kugadzikana: yakakodzera kushandiswa mukati mehuwandu hwePH3.0-11.0.
◆ Kusanaka uye kunhuhwirira, kusakanganiswa nemetabolism;inoshandiswa sezvokudya uye zvinodhaka zvinowedzera, hazvizogadziriswi muzvokudya, uye hazvizopi kupisa.
