Lo mhlathi uxoxa ngemeko ekhoyo ngoku eTshayina malunga nokusetyenziswa kweHydroxypropyl Methylcellulose (HPMC) kwimveliso yokutya.Okwangoku, ubungakanani bomgangatho wokutya we-HPMC osetyenziswa kushishino lokutya lwase-China usezantsi ngenxa yexabiso eliphezulu kunye nokusetyenziswa okulinganiselweyo.Nangona kunjalo, ngokukhula okuzinzileyo koshishino lokutya kwixesha elide kunye nokwandisa ulwazi lokutya okunempilo, izinga lokungena kwe-HPMC njengezongezo zezempilo kulindeleke ukuba linyuke kancinci kancinci.Ukusetyenziswa kwe-HPMC kunokuphucula iimveliso ezahlukeneyo ngokwandisa uzinzo, ukuthungwa, kunye nobomi beshelufu.Ke, kulindeleke ukuba ukusetyenziswa kwe-HPMC kwishishini lokutya kuya kukhula ngakumbi kwixesha elizayo.Oku kunokukhokelela ekunyuseni okutsha kunye nophuhliso kwishishini lokutya ukuhambisana nokutshintsha kwezinto ezikhethwa ngabathengi kunye nemfuno yemveliso yokutya enempilo, ekumgangatho ophezulu.
3. Udaka lwe-drymix yokwakha
Lo mhlathi uchaza izicelo ezahlukeneyo zeHydroxypropyl Methylcellulose (HPMC) kwishishini lodaka lodaka olumileyo.I-HPMC isetyenziswa ngokubanzi njenge-arhente yokugcina amanzi kunye ne-retarder, eyenza ukuba udaka luhlale lusebenza kwaye lumpompe ixesha elide.Ikwasebenza njenge-binder, ukuphucula ukusasazeka, kunye nokwandisa ixesha lokusebenza kwezinto zokwakha ezifana ne-plaster, i-putty powder, kunye nezinye iimveliso ezifanayo.I-HPMC ikwaluncedo kwithayile yokuncamathisela, ibhastile, kunye nokuhombisa iplastiki, ukubonelela ngokuqiniswa kunye nokunciphisa inani lesamente elifunekayo kwinkqubo.Ngeempawu ezigqwesileyo zokugcina amanzi, i-HPMC iphucula amandla omxube emva kokuqina kwaye inqande i-slurry ekuqhekekeni ngenxa yokoma ngokukhawuleza emva kwesicelo.Lilonke, i-HPMC sisithako esiyimfuneko kushishino lokwakha oluzalisekisa iimfuno ezahlukeneyo, ezinjengokuphucula ukusebenza kunye nokuphucula iimpawu zemveliso yokugqibela.
Uyisebenzisa njani iHydroxypropyl methylcellulose?
Indlela yokuqala
Ngenxa yokuhambelana kwe-HPMC, inokuxutywa ngokulula kunye nezinto ezahlukeneyo zomgubo ezifana nesamente, i-talc yamatye, kunye ne-pigments ukufezekisa umsebenzi ofunekayo.
1. Inyathelo lokuqala ekusebenziseni HPMC kukuxuba kunye nazo zonke ezinye izithako de yome ngokupheleleyo exutywe.Oku kuthetha ukuba i-HPMC kufuneka ixutywe kunye nezinye izinto zomgubo (ezifana nesamente, umgubo wegypsum, udongwe lwe-ceramic, njl. njl.) phambi kokongeza nawaphi na amanzi.
2. Kwinqanaba lesibini, umlinganiselo ofanelekileyo wamanzi wongezwa kumxube, kwaye uxutywe kwaye uxutywe de kube imveliso edibeneyo ichithwe ngokupheleleyo.Eli nyathelo liqinisekisa ukuba umxube uba yintlama efanayo enokuthi isetyenziswe ngokulula kwindawo oyifunayo.
Indlela yesibini
1.Isinyathelo sokuqala sibandakanya ukongeza umlinganiselo othile wamanzi abilayo kwisitya esixutywe kunye noxinzelelo oluphezulu lokucheba.Oku kunceda ukuqhekeza amasuntswana e-HPMC kwaye uqinisekise ukuba asasazeke ngokulinganayo emanzini.
2.Kwinqanaba lesibini, ukuvuselela kufuneka kuvulwe ngesantya esiphantsi, kwaye imveliso ye-HPMC kufuneka ihlulwe ngokucothayo kwisitya esishukumisayo.Oku kunceda ukuthintela amaqhuma ukuba enze kwaye iqinisekisa i-HPMC isasazwe ngokulinganayo ngaphakathi kwisisombululo.
3.Inyathelo lesithathu libandakanya ukuqhubeka nokuvuselela de onke amasuntswana emveliso ye-HPMC afakwe emanzini.Le nkqubo iqinisekisa ukuba amasuntswana e-HPMC amanzi ngokupheleleyo kwaye alungele ukunyibilika.
4.Kwinqanaba lesine, imveliso ye-HPMC ishiywe ukuba imele ukupholisa kwendalo ukuze inyibilike ngokupheleleyo.Emva koko, isisombululo se-HPMC sishukunyiswa ngokupheleleyo phambi kokusetyenziswa.Kubalulekile ukuba uqaphele ukuba i-agent ye-antifungal kufuneka yongezwe kumama otywala ngokukhawuleza.
5.Kwinqanaba lesihlanu, imveliso ye-HPMC ihluzwa kancinane kwisitya sokuxuba.Kubalulekile ukuphepha ukongeza isixa esikhulu semveliso ye-HPMC eyenze amaqhuma ngqo kwisitya sokuxuba.
6.Ekugqibeleni, kwinqanaba lesithandathu, ezinye izithako kwifomula zongezwa ukugqiba ukulungiswa kwemveliso egqityiweyo.
