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 liyehla kwiqondo elithile lobushushu (imveliso yeShijiazhuang Lvyuan Cellulose Co., Ltd. ngama-60 degrees Celsius), i-viscosity ibonakala ngokucothayo de kube yi-colloid ebonakalayo ebonakalayo.

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 ngomgubo, zixutywe ngokucokisekileyo kunye nomxube, zize zichithwe ngokungeza amanzi, ngoko i-HPMC inokuchithwa ngaphandle kokubambisana 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 kakhulu kwiimveliso zemichiza yemihla ngemihla ezifana neglue elulwelo, ipeyinti kunye nesicoci.
