IHydroxypropyl methylcellulose yenye yezongezo ze-cellulose ether ezibalulekileyo kudaka olomileyo kwaye inemisebenzi emininzi kudaka.Imisebenzi ephambili ye-hydroxypropyl methylcellulose kudaka lwesamente kukugcina amanzi kunye nokuqina.Ukongeza, ngenxa yokusebenzisana kwayo nenkqubo yesamente, inokudlala indima ekufakeni umoya, ukubuyisela umva, kunye nokuphucula amandla ebhondi.Impembelelo.
Eyona ntsebenzo ibalulekileyo ye-hydroxypropyl methylcellulose kumdaka kukugcina amanzi.Njengomxube we-ether we-cellulose kudaka, i-hydroxypropyl methylcellulose ingasetyenziswa phantse kuzo zonke iimveliso zodaka, ngenxa yeempawu zayo zokugcina amanzi.Ngokuqhelekileyo, ukugcinwa kwamanzi kwe-hydroxypropyl methylcellulose kuhambelana ne-viscosity yayo, i-degree of substitution and particle size.
I-Hydroxypropyl methylcellulose isetyenziswe njenge-thickener, kwaye umphumo wayo wokuqina uhambelana nenqanaba lokutshintshwa, ubungakanani beqhekeza, i-viscosity kunye neqondo lokuguqulwa kwe-hydroxypropyl methylcellulose.Ngokuqhelekileyo, iqondo eliphezulu lokuthatha indawo kunye ne-viscosity ye-cellulose ether, incinci isayizi ye-particle kwaye ibonakala ngakumbi isiphumo sokuqina.
Kwi-hydroxypropyl methylcellulose, ukuqaliswa kwamaqela e-methoxy kunciphisa amandla angaphezulu kwesisombululo samanzi esine-hydroxypropyl methylcellulose, ukuze i-hydroxypropyl methylcellulose ibe nefuthe lokungenisa umoya kwi-samente mortar.Yazisa isixa esifanelekileyo samaqamza eludaka.Ngenxa "yempembelelo yebhola" yamaqamza,
Ukusebenza kokwakhiwa kodaka kuphuculwe, ngelixa ukuqaliswa kweebhubhu zomoya kwandisa isivuno somdaka.Kakade ke, ubungakanani bomoya ongenisiweyo kufuneka ulawulwe.Xa umoya omninzi ufakwe, unokuchaphazela kakubi amandla omdaka.
I-Hydroxypropyl methylcellulose iya kulibazisa inkqubo yokumisela i-samente, icothe ukuseta kunye nokuqina kwenkqubo ye-samente, kwaye yandise ixesha lokuvula lodaka ngokufanelekileyo.Nangona kunjalo, esi siphumo asilungile kumdaka kwiindawo ezibandayo.
Njengombhobho wepolymer ende ende, i-hydroxypropyl methylcellulose inokuphucula ukusebenza kwe-bonding kunye nesiseko esisisiseko ngelixa igcina ngokupheleleyo umthamo womswakama we-slurry xa yongezwa kwinkqubo ye-samente.
Iipropati eziphambili ze-HPMC kumdaka zibandakanya: ukugcinwa kwamanzi, ukuqina, ukwandisa ixesha lokumisela, ukungena emoyeni, ukuphucula amandla ebhondi, njl.
