Kuvandudzwa uye kushandiswa kwe cellulose ether

Cellulose ana ana vana vanokura kukura kwakakosha uye vakawana akawanda ekushandisa maindasitiri akasiyana siyana nekuda kwezvivakwa zvavo zvakasarudzika uye zvakasarudzika. Heano kuongorora kwekukura uye kushandiswa kwe cellulose etana:

1. Developmentical Development: Kuvandudza kweCellulose anaiters kudzoka kuzere kwezana ramakore rechi 19, nekuwanikwa kwemaitiro ekugadzirisa kwemakemikari moleulose moleulose maneja. Kuedza kwekutanga kwakanangana nehunyanzvi hwekutamba kuunza hydroxylkyl mapoka, akadai sehydroxypruppropyl uye hydroxytHyl, kuCellulose Backbone.
2. Chemical shanduko: cellulose anaiters yakashongedzwa kuburikidza nemakemikari kugadziridzwa kwemheremalose, kunyanya nekutsvagira kana gadziriso yekuita. Kuwedzera kunosanganisira kutsiva mapoka ehydroxyl emakomputa ane mapoka e-ether mapoka, apo nekutsiva mapoka esters. Uku kushandurwa kunopa zvivakwa zvakasiyana-siyana kune cellulose ana vanayo, senge solubility mumvura kana organic soles, firimu-kugadzira kugona, uye kudzora viscosity.
3. Mhando dzeMaCellulose anaTers: Zvakajairika cellulose ethyl Cellulosel Cellelose (HPD), CarboxyProvyl Cellulose (CMC), uye HydroxyPropyll Metherose (HPMC). Rudzi rwese rwakasarudzika zvimiro zvakasarudzika uye zvakakodzera kuti zvive zvingangoita zvikumbiro.
4. Zvikumbiro mukuvaka: Cellulose ana vanayo vanoshandiswa zvakanyanya muindasitiri yekuvaka seyakawedzera mune zvekushandisa, vakadaro sevhu, uye zvigadzirwa zveGypsum. Ivo vanovandudza basa rekushanda, kuchengetwa kwemvura, kuderedza, uye kuita kwese kwezvinhu izvi. HPMC, kunyanya, yakashandiswa zvakanyanya mumatehwe emateki, anopa, uye anozvimiririra makomendi.
5. Zvikumbiro muMishonga: Cellulose Vanosangana nemari yakakosha mune yemishonga yekugadzira semabhandi, disintegraphts, mafirimu-mafirimu, uye viscosity modifiers. Ivo vanowanzoshandiswa mukukara kwesheni, vanodzorwa-kuburitswa, kumiswa, uye mhinduro yeOphthalmic nekuda kwekukanganisa kwavo, kugadzikana, uye profiles.
6. Zvikurudzirwi muChikafu uye Chengetwa Chengetedza: Muindasitiri yechikafu, cellulose ana ana mherzesa, uye emulsifiers mune dzakasiyana siyana zvezvigadzirwa, kusanganisira masaga, zvipfeko, zvigadzirwa zvemukaka, uye zvinhu zvakabikwa. Muzvigadzirwa zvega, ivo vanowanikwa mune mazino, Shampoo, lotions, uye zvizarisi zvekukora kwavo uye zvinonyungudika zvivakwa.
7. Kufunga nezvemamiriro ekunze: Cellulose ana anawanzoonekwa seyakachengeteka uye nharaunda zvine hushamwari zvinhu. Ivo vane bioderable, kuvandudzwa, uye zvisiri zvepfu, kuita ivo nzira dzinoyevedza kune dzimba dzekudyidzana mune akawanda mashandisiro.
8. Kuenderera mberi kwekutsvaga uye kutsvagisa: Kutsvaga mheremalose ana vana kufambira mberi, nekutarisa pakuvandudza midziyo ine zvivakwa, sekupembera kwekushisa Pamusoro pezvo, kuedza kuri kuendesa kudzokorora maitiro ekugadzira, kuvandudza kuchengetedza, uye kuongorora mitsva mitsva muminda inobuda.

Cellulose ana ana vana vanomiririra kirasi yakati wandei yePolymers ine huwandu hwakawanda hwekushandisa maindasitiri. Kukura kwavo uye application kwakatyisidzirwa nekuenderera mberi kwekutsvaga, kufambira mberi kwehunyanzvi, uye zvinodikanwa zvekushandisa zvakaringana uye zvinoshanda mumatunhu akasiyana siyana.
