I-Hydroxypropyl methylcellulose (HPMC) yi-non-ionic cellulose ether eyenziwe nge-cellulose yendalo yepolymer ngokusebenzisa uthotho lweenkqubo zeekhemikhali. Ziyimpuphu emhlophe engenavumba, engenancasa kwaye engenatyhefu evuvukala ibe yisisombululo se-colloidal esicacileyo okanye esinamafu kancinci emanzini abandayo. Ineempawu zokuqina, zokubopha, zokusasaza, zokuhlanganisa, zokwenza ifilimu, zokumisela, zokufaka i-gelling, zokufaka i-gelling, zokusebenzisa umphezulu, zokugcina umswakama kunye nezokukhusela i-colloid. I-Hydroxypropyl methylcellulose kunye ne-methylcellulose zingasetyenziswa kwizixhobo zokwakha, kushishino lwepeyinti, kwi-resin yokwenziwa, kushishino lwe-ceramic, kumayeza, ekutyeni, kwilaphu, kwezolimo, kwi-daily chemical nakwezinye iishishini.

⑵ Ukugcinwa kwamanzi amaninzi, ukwandisa ixesha lokugcina i-mortar, ukuphucula ukusebenza kakuhle, kunye nokwenza kube lula ukufuma kunye nokuqina kwe-mortar ukuze kuveliswe amandla aphezulu oomatshini.
⑶ Lawula ukuhambelana kwesamente ukuze wenze umphezulu ofanelekileyo.
3. Idaka lokubumba
⑴ Yomeleza ukunamathelana nomphezulu womthi, yonyusa ukugcinwa kwamanzi, kwaye yonyusa amandla e-mortar.
⑵ Phucula ukutyeba kunye ne-plasticity, kwaye uphucule ulwakhiwo; i-mortar ephuculwe yi-cellulose ether kulula ukuyakha, igcina ixesha lokwakha kwaye inciphisa iindleko zokwakha.
⑶ I-cellulose ether egcina amanzi amaninzi kakhulu, ifanelekile kwizitena ezifunxa amanzi amaninzi.
4. Isizalisi sejoyinti yephaneli
⑴Igcina amanzi kakuhle, yandisa ixesha lokuvula kwaye iphucula ukusebenza kakuhle. I-oil ephezulu, kulula ukuyixuba. ⑵ Iphucula ukumelana nokushwabana kunye nokumelana nokuqhekeka, iphucula umgangatho womphezulu wokugquma. ⑶ Iphucula ukunamathela komphezulu wokubophelela kwaye inike ubume obuthambileyo nobuthambileyo.
5. Isincamathelisi sethayile ⑴Kulula ukuzomisa izithako zomxube, akukho ziqhuma, kwandisa isantya sokusetyenziswa, kuphucula ukusebenza kolwakhiwo, konga ixesha lokusebenza kwaye kunciphise iindleko zokusebenza. ⑵ Ngokwandisa ixesha lokuvula, ukusebenza kakuhle kwethayile kunokuphuculwa kwaye isiphumo esihle sokuncamathela sinokubonelelwa.
6. Izixhobo zomgangatho ezizilinganisayo ⑴ zibonelela nge-viscous kwaye zingasetyenziswa njengezongezo zokulwa ne-dimentation. ⑵Phucula ukufunxwa kwamanzi kwaye uphucule ukusebenza kakuhle kokugawulwa komhlaba. ⑶ Lawula ukugcinwa kwamanzi kunye nokuncitshiswa, unciphise imifantu kunye nokuncitshiswa komhlaba.
7. Ipeyinti esekwe emanzini ⑴Thintela ukuna kwemvula eqinileyo kwaye yandise ubomi besikhongozeli semveliso. Uzinzo oluphezulu lwebhayoloji, ukuhambelana okuhle nezinye izinto. ⑵ Iphucula ukunyibilika kwamanzi, ibonelela ngeempawu ezilungileyo zokuchasana nokuqhekeka, ukuchasana nokuwa kunye nokulinganisa, kwaye iqinisekise ukugqitywa komphezulu okugqwesileyo.
8. Umgubo wephepha lodonga ⑴ Nyibilikisa ngokukhawuleza ngaphandle kwamaqhuma, nto leyo ilungele ukuxuba. ⑵ Inika amandla aphezulu okubopha.
9. Ibhodi yesamente ekhutshiweyo (1) inamathele kakhulu kwaye ithambile, kwaye iphucula ukusebenza kweemveliso ezikhutshiweyo. ⑵ Iphucula amandla aluhlaza, ikhuthaza ukufuma kunye nefuthe lokunyanga, kwaye yandisa isivuno.
10. Iimveliso ze-HPMC ezinikezelwe kwi-mortar exutyiweyo esele ilungisiwe Iimveliso ze-HPMC ezinikezelwe kwi-mortar exutyiweyo esele ilungisiwe zigcina amanzi ngcono kwi-mortar exutyiweyo esele ilungisiwe kuneemveliso eziqhelekileyo, ziqinisekisa ukufuma okwaneleyo kwezinto ezingezizo izinto ezingaphiliyo, zithintela kakhulu ukuncipha kwamandla e-bond abangelwa kukoma kakhulu, kunye nokuqhekeka okubangelwa kukuncitshiswa kokoma. I-HPMC ikwanayo nefuthe elithile lokungenisa umoya. Imveliso ye-HPMC esetyenziselwa ngokukodwa i-mortar exutyiweyo esele ilungisiwe inomlinganiselo ofanelekileyo wamaqamza omoya aqeqeshwe ngomoya, afanayo nancinci, anokuphucula amandla kunye nokuthambisa i-mortar exutyiweyo esele ilungisiwe. Imveliso ye-HPMC esetyenziselwa ngokukodwa i-mortar exutyiweyo esele ilungisiwe inefuthe elithile lokulibazisa, elinokwandisa ixesha lokuvula i-mortar exutyiweyo esele ilungisiwe kwaye linciphise ubunzima bokwakha.
