Kwimveliso yephepha kunye neengubo zokugqoka, iphinda isetyenziswe njenge-agent-forming agent ukuze kuphuculwe ukugudiswa komphezulu kunye nokuqina kwemveliso.
5. Iipropati zokunqunyanyiswa kunye nokusabalalisa
I-Methyl cellulose ether ineepropathi ezilungileyo zokumisa kunye nokusabalalisa, ezivumela ukuba zisasaze iincinci eziqinileyo ngokulinganayo kwimiqulu. Le propati ibaluleke kakhulu kwiingubo kunye nepeyinti, apho ikhusela ukuhlalisa i-pigment kwaye iphucula ukuzinza kwepeyinti kunye nokufana. Kwizinto zokuthambisa, inokuqinisekisa ukuhanjiswa okufanayo kweengqungquthela kunye nezithako, ukuphucula ukuthungwa kunye nokusetyenziswa kwesiphumo semveliso.
6. I-inertness yekhemikhali kunye nokhuseleko
I-Methyl cellulose ether izinzile ngokwekhemikhali kwaye ayisebenzi kunye namanye amacandelo ekhemikhali, iqinisekisa ukhuseleko lwayo kwizicelo ezahlukeneyo. Oku kuyenza isetyenziswe kakhulu ekutyeni, kumayeza nakwizithambiso. Njengesongezo sokutya, i-methylcellulose ether ithathwa njengekhuselekile, ayinayo nayiphi na ityhefu, kwaye ayiyi kugaywa kwaye ifakwe emzimbeni. Njengomxhasi wamachiza, inokubonelela ngokuzinza kweziyobisi, ukulawula izinga lokukhululwa, kunye nokuphucula incasa kunye nokugwinya.
7. Biocompatibility
I-Methyl cellulose ether ine-biocompatibility efanelekileyo kwaye ifanelekile ukusetyenziswa kumayeza kunye neemveliso zokunyamekela komntu. Njengomxhasi wamachiza, inokwenza ukuhambelana kakuhle kunye nezithako ezisebenzayo ngaphandle kokuchaphazela ukusebenza kweyeza, ngelixa iphucula incasa kunye nokukhulula ukusebenza kweyeza. Kwiimveliso ze-ophthalmic, i-methylcellulose ethers nayo isetyenziswa njenge-lubricant kunye ne-humectants ukuphucula induduzo yemveliso kunye nokusebenza kakuhle.
8. Ukuvumelana nokusingqongileyo
