IHydroxypropyl methylcellulose (HPMC)Yikhompawundi eguquguqukayo esetyenziswa ngokubanzi kwiintlobo ngeentloboamashishiningenxa yeempawu zayo ezininzi.Umba omnye obalulekileyo ochaphazela ukusebenza kwe-HPMC kukucoceka kwayo, okunokuthi kube nefuthe elibonakalayo kwi-viscosity yayo kunye, ngenxa yoko, ukusetyenziswa kwayo.Eli nqaku lijonge kunxibelelwano phakathi kobunyulu be-HPMC kunye ne-viscosity, likhanyisela iimpembelelo zayo kumacandelo ahlukeneyo.
HPMCkunye nokubaluleka kwayo:
I-HPMC, ephuma kwi-cellulose yendalo, idlula ukuguqulwa kweekhemikhali ukwenza i-polymer yokwenziwa eneempawu ezikhethekileyo.Le khompawundi ifumana izicelo kumayeza, izithambiso, ulwakhiwo, nokunye, ngenxa yokuqina kwayo, ukunqumamisa, kunye nobuchule bokwenza ifilim.Nangona kunjalo, ukucoceka kwe-HPMC kuvela njengento ebalulekileyo echaphazela le misebenzi.
Impembelelo yoBunyulu kwiViscosity:
Ubunyulu budlala indima ebalulekileyo ekumiseleni i-viscosity yezisombululo ze-HPMC.Amanqanaba aphezulu okucoceka ngokubanzi akhokelela kwiziphumo ezihambelanayo kunye neziqikelelwayo ze-viscosity.Ukungcola, okufana nentsalelaiselulosi, inokwazisa ukuhluka kwi-viscosity, echaphazela ukusebenza ngokubanzi kweemveliso ezisekelwe kwi-HPMC.
Ukutyebisa kunye neePropathi zokuGelling:
Kwizicelo ezifuna ukutyeba kunye ne-gelling, njengemveliso yokutya kunye nokwakhiwa kwamayeza,HPMCubunyulu buchaphazela ngokuthe ngqo ukuthungwa okufunwayo kunye nokuzinza.Ubunyulu obuphezulu HPMC iqinisekisa ulawulo oluchanekileyo phezu kwe-viscosity, ukuvelisa iimveliso eziphezulu kunye nomgangatho ohambelanayo.
Iimpawu zokunqunyanyiswa:
Ukukwazi kwe-HPMC ukunqumamisa amasuntswana ekuxutyweni kolwelo kuchatshazelwa bubunyulu bayo.Ukungcola kunokuthintela ukubunjwa kokumiswa okuzinzileyo, okunokuthi kuchaphazele ukusebenza kwamayeza olwelo lomlomo kunye nokunye ukumiswa.
Ukwenziwa kweFilimu kunyeUkwaleka:
Ukucoceka kuphembelela iipropathi zokwenza ifilim ze-HPMC, ebaluleke kakhulu kwizicelo ezifana nokugquma ithebhulethi yamayeza.I-HPMC engaguqukiyo esulungekileyo iqinisekisa iingubo ezifanayo nezithembekileyo, ezichaphazela iiprofayili zokukhutshwa kweziyobisi kunye nokuzinza kweshelufu.
Ushishino loKwakha:
Kwicandelo lokwakha, apho i-HPMC isetyenziswa njengesongezo sesamente, ukucoceka kuchaphazela ngokuthe ngqo amandla okugcina amanzi, ukusebenza, kunye neempawu zokuncamathelisa.Ucoceko oluphezulu lwe-HPMC luncedisa ukuhambelana okufunwayo kunye nokusebenza kwezinto zokwakha.
Ukucoceka kwe-HPMC yipharamitha ebalulekileyo echaphazela kakhulu i-viscosity yayo kwaye, ngenxa yoko, ukusebenza kwayo kumashishini awohlukeneyo.Amanqanaba aphezulu okucoceka akhokelela kwiziphumo ezithembekileyo nezingaguquguqukiyo ekutyebeni, ekumisweni, nakwizicelo zokwenza ifilim.Abavelisi kunye nabaphandi ngokufanayo kufuneka babeke phambili umgangatho kunye nokucoceka kwe-HPMC ukuqinisekisa ukusebenza kakuhle kunye nokuphucula ukusebenza kakuhle kweemveliso kumacandelo ahlukeneyo.Njengoko eli nqaku liqaqambisa, ukuqonda impembelelo yococeko lwe-HPMC kwi-viscosity ngundoqo ekuvuleni amandla ayo apheleleyo kwizicelo ezininzi.
