Ngokuphathelele ingxaki yobushushu bejeli yeHydroxypropyl Methyl Cellulose HPMC, Abasebenzisi abaninzi abafane banikele ingqalelo kwingxaki yobushushu begel yeHydroxypropyl Methyl Cellulose. Namhlanje, i-Hydroxypropyl Methyl Cellulose iqheleke ukwahlula ngokwe-viscosity yayo, kodwa kwezinye iindawo ezikhethekileyo kunye namashishini akhethekileyo, akwanelanga ukubonisa kuphela i-viscosity yemveliso. Oku kulandelayo kwazisa ngokufutshane ubushushu bejeli yeHydroxypropyl Methyl Cellulose.
Ubungakanani beqela le-Methoxyl lihambelana ngokuthe ngqo kwinqanaba le-cellulose sourization, kwaye umxholo weqela le-Methoxyl unokulungiswa ngokulawula ifomula, ubushushu bokuphendula kunye nexesha lokuphendula. Ngelo xesha, iqondo lokungasebenzi lichaphazela iqondo lokutshintshwa kweHydroxyethyl okanye iHydroxypropyl. Ngoko ke, ukugcinwa kwamanzi kwe-cellulose ether kunye nokushisa kwe-gel ephezulu kuya kuba mbi. Le nkqubo yokuvelisa kufuneka ihlolwe, ngoko ke akukhona ukuba ixabiso lokuvelisa i-cellulose ether liphantsi ukuba umxholo weMethoxy uphantsi, ngokuchaseneyo, ixabiso liya kuba phezulu.
Ukushisa kwe-gel kunqunywe ngamaqela e-methoxyl, kwaye ukugcinwa kwamanzi kunqunywe ngamaqela e-Hydroxypropoxy. Kukho amaqela amathathu kuphela athatha indawo ye-cellulose. Fumana ubushushu bakho obufanelekileyo bokusebenzisa, ukugcinwa kwamanzi okufanelekileyo, kwaye emva koko umisele imodeli yale cellulose.
Ubushushu bejeli buyinto ebalulekileyo ekusetyenzisweni kwei-cellulose ether. Xa ubushushu be-ambient budlula ubushushu be-gel, i-ether ye-cellulose iya kwahlulwa emanzini kwaye ilahlekelwe ukugcinwa kwayo kwamanzi. Ukushisa kwejel ye-cellulose ether kwimarike kunokwanelisa ngokusisiseko iimfuno zendawo yokusetyenziswa kodaka (ngaphandle kweendawo ezikhethekileyo). Mna ngokwam ndicinga ukuba akuyimfuneko ukuhlawula ingqalelo ekhethekileyo kwisalathiso sokusebenza sobushushu be-gel xa usebenzisa udaka. Ngokuqinisekileyo, ukuveliswa kwe-cellulose ether Abavelisi kufuneka bayiqwalasele.
