Iimpembelelo zoBubushushu kuGcino lwaManzi lweCellulose Ether

Iimpawu zokugcina amanzi e-cellulose ethers, kuquka i-carboxymethyl cellulose (CMC) kunye ne-hydroxyethyl cellulose (HEC), inokuphenjelelwa ngubushushu.Nazi iziphumo zobushushu kugcino lwamanzi lwe-cellulose ethers:

1. I-Viscosity: Kwiqondo lokushisa eliphezulu, i-viscosity ye-cellulose ether solutions iyancipha.Njengoko i-viscosity iyancipha, ukukwazi kwe-cellulose ether ukwenza ijeli edibeneyo kunye nokugcina amanzi kuncipha.Oku kunokubangela ukuncipha kogcino lwamanzi kumaqondo obushushu aphakamileyo.
2. Ukunyibilika: Ubushushu bunokuchaphazela ukunyibilika kwe-cellulose ethers emanzini.Ezinye ii-cellulose ethers zinokuba zicuthe ukunyibilika kumaqondo obushushu aphezulu, okukhokelela ekunciphiseni komthamo wokugcina amanzi.Nangona kunjalo, ukuziphatha kwe-solubility kunokwahluka ngokuxhomekeke kuhlobo oluthile kunye nebakala le-cellulose ether.
3. Izinga loHlelo: Amaqondo obushushu aphezulu anokukhawulezisa isantya se-hydration ye-cellulose ethers emanzini.Oku kuqala kunokunyusa umthamo wokugcina amanzi njengoko i-ether cellulose idumba kwaye yenze ijeli ye-viscous.Nangona kunjalo, ukuvezwa kwexesha elide kumaqondo obushushu aphakamileyo kunokukhokelela ekuthotyweni kwangaphambi kwexesha okanye ukuwohloka kwesakhiwo sejeli, okukhokelela ekunciphiseni ukugcinwa kwamanzi ngokuhamba kwexesha.
4. Ukuguquka kwamanzi: Amaqondo obushushu anyusiweyo anokunyusa izinga lokunyuka kwamanzi abe ngumphunga kwizisombululo ze-cellulose ether okanye imixube yodaka.Lo mphunga ukhawulezayo unokuphelisa isiqulatho samanzi kwisixokelelwano ngokukhawuleza ngakumbi, okunokubakho ukunciphisa ukusebenza kwezongezo zokugcina amanzi njengeether ze-cellulose.
5. Iimeko zesicelo: Ubushushu bunokuchaphazela iimeko zesicelo kunye neeparitha zokusetyenzwa kweemveliso ze-cellulose ether-containing.Ngokomzekelo, kwizicelo zokwakha ezifana ne-tile adhesives okanye i-cement-based mortars, amaqondo okushisa aphezulu anokukhawuleza ukumisela okanye inkqubo yokunyanga, echaphazela ukusebenza kunye nokusebenza kwezinto.
6. Uzinzo lwe-Thermal: Ii-ether ze-cellulose zibonisa ukuzinza okulungileyo kwe-thermal kuluhlu olubanzi lobushushu.Nangona kunjalo, ukuvezwa ixesha elide kumaqondo obushushu agqithisileyo kunokubangela ukuthotywa okanye ukubola kwamatyathanga epolymer, okukhokelela ekulahlekeni kweempawu zokugcina amanzi.Ukugcinwa ngokufanelekileyo kunye neemeko zokuphatha kubalulekile ukugcina ingqibelelo kunye nokusebenza kwe-cellulose ethers.

ngelixa ubushushu bunokuchaphazela iipropathi zokugcinwa kwamanzi ze-cellulose ethers, iimpembelelo ezithile zinokwahluka ngokuxhomekeka kwizinto ezifana nohlobo lwe-cellulose ether, ugxininiso lwesisombululo, indlela yokusetyenziswa, kunye neemeko zokusingqongileyo.Kubalulekile ukuqwalasela le miba xa uqulunqa okanye usebenzisa iimveliso ezisekelwe kwi-cellulose ether ukuqinisekisa ukusebenza kakuhle phantsi kweemeko ezahlukeneyo zokushisa.
