1.Uhlelo:
HPMCingohlulwa ibe luhlobo olukhawulezileyo kunye nodidi olunyibilikayo olushushu. Iimveliso zohlobo olukhawulezayo zisasazeka ngokukhawuleza emanzini abandayo kwaye zinyamalale emanzini. Ngeli xesha, i-liquid ayinayo i-viscosity, kuba i-HPMC ihlakazekile kuphela emanzini kwaye ayinayo ukuchithwa kwangempela. Emva kwemizuzu emi-2, i-viscosity yolwelo yanda ngokuthe ngcembe ukuze yenze i-colloid ebonakalayo ebonakalayo. Iimveliso ezitshisayo ezitshisayo, xa zidibana namanzi abandayo, zinokuhlakazwa ngokukhawuleza emanzini ashushu kwaye zinyamalale emanzini ashushu. Xa amaqondo obushushu ehla ukuya kwiqondo elithile lobushushu, i-viscosity ibonakala kancinane de i-viscous colloid ecacileyo yenziwe. Uhlobo lwe-hot-melt lunokusetyenziswa kuphela kwi-putty powder kunye nodaka. Kwiglue yolwelo kunye nepeyinti, i-clumping phenomenon iya kwenzeka kwaye ayinakusetyenziswa. Uhlobo olukhawulezileyo lunoluhlu olubanzi lwezicelo. Ingasetyenziselwa kwi-putty powder kunye nodaka, kunye neglue elulwelo kunye nepeyinti, ngaphandle kokuchasana.
2.Indlela yokuphelisa:
Indlela yokunyibilika kwamanzi ashushu: Ekubeni i-HPMC inganyibiliki emanzini ashushu, i-HPMC inokusasazwa ngokufanayo kumanzi ashushu kwinqanaba lokuqala, emva koko inyibilike ngokukhawuleza ngexesha lokupholisa. Iindlela ezimbini eziqhelekileyo zichazwe ngolu hlobo lulandelayo: 1), faka isixa esifunekayo kwisikhongozeli samanzi ashushu kwaye ufudunyezwe ukuya kuma-70°C. I-hydroxypropyl methylcellulose yongezwa ngokuthe ngcembe ngokushukumisa okucothayo, ekuqaleni i-HPMC yadada phezu kwamanzi, kwaye ngokuthe ngcembe yenza i-slurry, eyapholiswa ngokuvuselela. 2), yongeza inani elifunekayo le-1/3 okanye i-2/3 yamanzi kwi-container, kwaye uyifudumeze ukuya kuma-70 ° C, ngokwendlela ye-1), ukusabalalisa i-HPMC, ulungiselele udaka lwamanzi ashushu; uze ungeze inani eliseleyo lamanzi abandayo kumanzi ashushu Kwi-slurry, umxube wawupholile emva kokuvuselela.
Indlela yokuxuba umgubo: Xuba i-HPMC yomgubo kunye nesixa esikhulu sezinye izinto ezinomgubo, xuba ngokucokisekileyo kunye nomxube, uze wongeze amanzi ukuze unyibilike, emva koko i-HPMC inokunyibilika ngeli xesha ngaphandle kokuhlanganisana, kuba yonke ikona encinci encinci ine-HPMC encinci kuphela Umgubo uya kunyibilika ngokukhawuleza xa udibana namanzi. ——Le ndlela isetyenziswa ngabavelisi be-putty kunye nodaka. [IHydroxypropyl methylcellulose (HPMC)isetyenziswa njenge-thickener kunye ne-ejenti yokugcina amanzi kwi-putty powder mortar]
