Abasebenzisi abaninzi abafane bathathele ingqalelo ingxaki yobushushu bejeli ye-hydroxypropyl methylcellulose.Kule mihla, i-hydroxypropyl methylcellulose ngokubanzi yahlulwa ngokwe-viscosity, kodwa kwezinye iindawo ezikhethekileyo kunye namashishini akhethekileyo, kuphela i-viscosity yemveliso ibonakala.Akwanelanga, oku kulandelayo kwazisa ngokufutshane ubushushu bejeli ye-hydroxypropyl methylcellulose.
Umxholo we-methyl acid uhambelana ngokuthe ngqo ne-ester-forming degree ye-cellulose ester, kwaye umxholo we-methyl acid ulungelelaniswa ukulawula ukubunjwa, ubushushu bokuphendula kunye nexesha lokuphendula.Ngelo xesha, inqanaba lesisombululo se-ether lichaphazela umxholo we-hydroxyethyl okanye i-hydroxyapatite.Ke ngoko, i-cellulose ethers kumaqondo obushushu aphakamileyo ejeli aya kuba manzi kancinci.Le nkqubo yokuvelisa kufuneka ibonakale, ngoko endaweni yamanqanaba aphantsi e-methoxides, i-cellulose ethers iya kuba phezulu kancinci kwixabiso.
Ukushisa kwe-gel kunqunywe nge-methoxide kunye ne-hydroxyproazepam kunye ne-hydroxyproxin.Ngamaqela amathathu kuphela anokutshintshwa kwi-cellulose.Fumana ubushushu obufanelekileyo, gcina ukufuma, kwaye umisele ipateni yepulp.Ubushushu bejeli yeyona nto ibalulekileyo yokusetyenziswa kwe-cellulose ether.Xa ubushushu be-ambient budlula ubushushu bejeli, i-ether ye-cellulose iya kukhutshwa emanzini.Ubushushu be-pulp kwimarike ikakhulu ukuhlangabezana neemfuno zesisombululo kwindawo (ngaphandle kweemeko ezikhethekileyo).Kukholelwa ukuba xa usebenzisa isisombululo, akuyimfuneko ukuhlawula ingqalelo ekhethekileyo kwiimpawu zokusebenza xa usebenzisa i-gel.Ngokuqinisekileyo, umenzi we-cellulose ether kufuneka athathele ingqalelo esi salathisi.
