Kwizinto zokuthambisa, kukho izinto ezininzi zekhemikhali ezingenambala nezingenavumba, kodwa zimbalwa izinto ezingeyotyhefu. Namhlanje, ndiza kwazisa, i-hydroxyethyl cellulose, exhaphake kakhulu kwizinto zokuthambisa ezininzi okanye izinto eziyimfuneko zemihla ngemihla.
I-Hydroxyethyl Cellulose【I-Hydroxyethyl Cellulose】
Ekwaziwa ngokuba yi-(HEC) sisixhobo esimhlophe okanye esimthubi okhanyayo, esingenavumba, esingenatyhefu esineefayibha okanye esinomgubo. Ngenxa yokuba i-HEC ineempawu ezilungileyo zokutyeba, ukuxhoma, ukusasaza, ukuxuba, ukubopha, ukwenza ifilimu, ukukhusela umswakama kunye nokubonelela nge-colloid ekhuselayo, isetyenziswa kakhulu kwizicelo zonyango kunye nezobuhle.
Iimpawu zeMveliso
1. I-HEC iyanyibilika emanzini ashushu okanye abandayo, kwaye ayitshisi xa ishushu kakhulu okanye ibila, nto leyo eyenza ukuba ibe neempawu ezahlukeneyo zokunyibilika kunye ne-viscosity, kunye ne-gelation engashushu;
2. I-non-ionic ngokwayo ingahlala kunye nezinye iipolymers ezinyibilikayo emanzini, ii-surfactants kunye neetyuwa, kwaye sisixhobo esihle kakhulu sokuxuba i-colloidal esinezisombululo ze-dielectric ezixineneyo kakhulu;
3. Umthamo wokugcina amanzi uphindwe kabini kunowe-methyl cellulose, kwaye unolawulo olungcono lokuhamba kwamanzi;
4. Xa kuthelekiswa ne-methyl cellulose eyaziwayo kunye ne-hydroxypropyl methyl cellulose, amandla okusasaza e-HEC ngawona mabi kakhulu, kodwa i-colloid ekhuselayo inamandla amakhulu.
indima kwizinto zokuthambisa
Ubunzima beemolekyuli zezinto zokuthambisa, ubuninzi beekhompawundi zendalo, izinto ezenziweyo kunye nezinye izinto zahlukile, ngoko ke kuyimfuneko ukongeza iarhente yokunyibilikisa ukuze zonke izithako zidlale indima engcono. Iimpawu zokunyibilika kunye ne-viscosity ze-hydroxyethyl cellulose zidlala indima ngokupheleleyo, kwaye zigcina ibhalansi, ukuze imo yokuqala yezinto zokuthambisa igcinwe ngamaxesha onyaka abandayo nobushushu. Ukongeza, ineempawu zokuthambisa kwaye ixhaphakile kwizinto zokuthambisa kwiimveliso zokuthambisa. Ngokukodwa, iimaski, ii-toners, njl. phantse zonke zongezwa.
imiphumela
I-Hydroxyethyl cellulose esetyenziswa kwizinto zokuthambisa ayinabungozi xa kusetyenziswa izinto zokuthambisa, izinto zokuthambisa, njl. Kwaye ithathwa njengemveliso yokhuseleko lokusingqongileyo ekwiNombolo 1 yi-EWG.
