Umahluko phakathi kweMveliso eNyangayo yoMphezulu kunye neNgeyiyo iNyanga yeMveliso ye-HPMC ye-KimaCell

I-KimaCell™ HPMC (iHydroxypropyl Methyl Cellulose) yi-ether eselulosi esetyenziswa ngokubanzi eyaziwa ngogcino lwamanzi olugqwesileyo kunye neempawu zokuphucula ukusetyenzwa. Isetyenziswa ngokuqhelekileyo kwizicelo ezahlukeneyo, kubandakanya ukwakhiwa, iiseramics, kunye neemveliso zokhathalelo lomntu. Umba omnye obalulekileyo wemveliso ye-HPMC lunyango lomphezulu we-ether cellulose. Kweli nqaku, siza kuxoxa ngomahluko phakathi kwemveliso ye-HPMC enyangwe ngomphezulu kunye nengaphathwanga ngomphezulu.

Iimveliso ze-KimaCell™ ze-HPMC eziphathwe ngomphezulu ze-KimaCell™ ze-HPMC eziphathwe ngomphezulu zii-ether ze-cellulose eziye zalungiswa ngenkqubo eyaziwa njengonyango lwangaphezulu. Le nkqubo ibandakanya ukongeza umaleko we-hydrophobic kumphezulu we-cellulose ether particles. Umaleko we-hydrophobic uqhele ukwenziwa ngamafutha acid okanye ezinye iikhompawundi ezifanayo.

Ukongezwa koluhlu lwe-hydrophobic lutshintsha iimpawu eziphezulu ze-cellulose ether particles. Oku kubangela ukuchasana kwamanzi okuphuculweyo kunye ne-dispersibility ye-cellulose ether particles. Iimveliso ze-KimaCell™ zeHPMC eziphathwe ngomphezulu ziluncedo kakhulu kwizicelo apho uxhathiso lwamanzi lubalulekile, njengezinto zokuncamathelisa iithayile okanye iinkqubo zokugqiba ukugquma kwangaphandle.

Olunye uncedo lweemveliso ze-KimaCell™ HPMC eziphathwe phezulu kukuphucula ukusebenza kwazo. Inkqubo yonyango yomphezulu iphakamisa i-lubricity ye-cellulose ether particles, okwenza kube lula ukusabalalisa kunye nokunciphisa umthamo womoya ofakwe kumxube. Oku kubangela ukuthungwa okuhambelanayo kunye nokugudileyo, okubalulekileyo kwizicelo ezifana ne-skim coating okanye i-cement renders.

Iimveliso ze-KimaCell™ HPMC ezinganyangekiyo ezingoMphezulu Iimveliso ze-KimaCell™ ze-HPMC zii-cellulose ether ezingakhange zinyangwe phezulu. Ezi mveliso zisetyenziswa ngokuqhelekileyo kwizicelo apho ukunganyangeki kwamanzi kungeyona nto ibalulekileyo. Iimveliso ze-HPMC ze-KimaCell™ ezingaphathwanga ngomphezulu zisetyenziswa kakhulu kwizicelo ezinje ngepeyinti, izinto zokuthambisa, kunye namayeza.

Xa kuthelekiswa neemveliso eziphathwe umphezulu zeKimaCell™ HPMC, iimveliso ezinganyangekiyo zidla ngokuxhathisa amanzi kwaye azihlakazeka kangako. Oku kuthetha ukuba banokutyekela ngakumbi ekudibaneni okanye ukuzinza kwiinkqubo ezinamanzi. Nangona kunjalo, iimveliso ze-KimaCell™ HPMC ezinganyangwanga ebusweni zisabonelela ngogcino lwamanzi olugqwesileyo kunye neepropathi eziphucula ukusetyenzwa, zizenza zilungele uluhlu olubanzi lwezicelo.

Ukukhetha iMveliso ye-HPMC eLungileyo ye-KimaCell™ Xa ukhetha imveliso efanelekileyo ye-KimaCell™ HPMC kwisicelo esithile, kubalulekile ukuqwalasela imiba efana nokunganyangeki kwamanzi, ukusebenza, kunye nokusasazeka. Ukuba uxhathiso lwamanzi lubalulekile, ngoko ke imveliso ye-KimaCell™ HPMC enyangwe ngomphezulu inokuba lolona khetho lulungileyo. Ngakolunye uhlangothi, ukuba ukunganyangeki kwamanzi akuyiyo inkxalabo, ngoko ke imveliso ephathwayo engeyiyo inokuthi ifaneleke ngakumbi.

Eminye imiba ekufuneka iqwalaselwe xa ukhetha imveliso ye-KimaCell™ HPMC ibandakanya ubungakanani bamasuntswana, i-viscosity, kunye nenqanaba lokutshintsha. Ubungakanani be-particle kunye ne-viscosity inokuchaphazela ukusebenza kunye ne-dispersibility yemveliso, ngelixa i-degree of substitution inokuchaphazela iipropati zokugcina amanzi.

Ukuqukumbela, owona mahluko uphambili phakathi kwemveliso ye-KimaCell™ HPMC enyangwe ngomphezulu kunye nengaphathwanga ngomphezulu kukunganyangeki kwamanzi, ukusasazeka, kunye neempawu zokuphucula ukusebenza. Iimveliso ezihlanjululwayo zibonelela ngokuphucuka kokumelana kwamanzi kunye nokusebenza, ngelixa iimveliso ezingaphathwanga zisetyenziswa ngokuqhelekileyo kwizicelo apho ukunganyangeki kwamanzi kungeyona nto ibalulekileyo. Xa ukhetha imveliso ye-KimaCell™ HPMC, kubalulekile ukuqwalasela imiba efana nokunganyangeki kwamanzi, ukusetyenzwa, kunye ne-dispersibility, kunye nobungakanani bamasuntswana, i-viscosity, kunye neqondo lokutshintsha.
