1.Uhlelo:
HPMC inokohlulwa ibe uhlobo ngoko nangoko kunye nohlobo hot-nyibilika.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, emva koko wongeze amanzi ukuze unyibilike, emva koko i-HPMC inokunyibilika ngeli xesha ngaphandle kokudityaniswa, kuba ikona nganye encinci inentwanana kuphela. I-HPMC Umgubo uya kunyibilika ngokukhawuleza xa udibana namanzi.——Le ndlela isetyenziswa ngabavelisi be-putty kunye nodaka.[I-Hydroxypropyl methylcellulose (HPMC) isetyenziswa njenge-thickener kunye ne-arhente yokugcina amanzi kwiputty powder mortar]
