Zingaphi iindidi zeHydroxypropyl methylcellulose (HPMC)?

IHydroxypropyl methylcellulose (HPMC) yohlulwe ngokohlobo olukhawulezileyo kunye nohlobo olunyibilikayo olushushu.

NgephanyazoIHydroxypropyl methylcellulose (HPMC)ihlakazeka ngokukhawuleza emanzini abandayo kwaye inyamalale emanzini.Ngeli xesha, ulwelo akukho viscosity, kuba HPMC isasazwe kuphela emanzini kwaye ayinyibiliki ngokwenene.Malunga nemizuzu emi-2, i-viscosity yolwelo yanda ngokuthe ngcembe, yenza i-colloid ebonakalayo ebonakalayo.

I-Hot-melt Hydroxypropyl methylcellulose (HPMC), xa zidibene emanzini abandayo, ziyakwazi ukusasazeka ngokukhawuleza emanzini ashushu kwaye zinyamalale emanzini ashushu.Xa iqondo lobushushu lehla kwiqondo lobushushu elithile (imveliso Shijiazhuang Lvyuan Cellulose Co., Ltd. ngama-60 degrees Celsius), viscosity ngokucothayo ibonakala de A transparent viscous colloid yenziwe.

I-Hot-melt Hydroxypropyl methylcellulose (HPMC) isetyenziswa ngokubanzi kwi-putty powder kunye nodaka.Indlela yokuxuba umgubo iyamkelwa: i-HPMC powder ixutywe kunye nomthamo omkhulu wezinye izinto ezixutywe ngumgubo, zixutywe ngokucokisekileyo kunye nomxube, zize zichithwe ngokungeza amanzi, ngoko i-HPMC inokuchithwa ngaphandle kokubumbana kwe-Clumping, kuba ikona nganye encinci iqulethe kuphela. i-HPMC powder encinci, eya kuchithwa ngokukhawuleza xa idibana namanzi.

Instant Hydroxypropyl methylcellulose (HPMC) inoluhlu olubanzi lwezicelo.Ukongeza kwi-putty powder kunye nodaka, isetyenziswa ngokubanzi kwiimveliso zemichiza yemihla ngemihla njengeglue elulwelo, ipeyinti, kunye nesicoci.
