IHydroxypropyl methylcellulose (HPMC) sisongezo esisetyenziswa ngokuqhelekileyo ekwenzeni udaka, ibonelela ngeempawu ezibalulekileyo ezifana nokusebenza okuphuculweyo, ukubambelela, kunye nokugcinwa kwamanzi.Nangona kunjalo, ukumisela isixa esifanelekileyo se-HPMC ukuba sibandakanywe kwinkqubo yokwenziwa kodaka kubalulekile ukuphumeza ukusebenza ngokupheleleyo.
Izinto ezichaphazela umxholo we-HPMC kuMdaka:
Zininzi izinto ekufuneka ziqwalaselwe xa kumiselwa owona mxholo we-HPMC ongowona uphezulu eludaka:
Ukungqinelana okufunekayo: Umxholo we-HPMC uchaphazela kakhulu ukuhambelana kunye nokusebenza kodaka.Ugxininiso oluphezulu lwe-HPMC lukhokelela kwimixube eyongezelelekileyo yeplastiki kunye nemixube edibeneyo, ephucula ukusebenziseka lula.Nangona kunjalo, umxholo ogqithisileyo we-HPMC unokukhokelela kudaka oluncangathi kakhulu okanye "ibhotolo", nto leyo eyenza kube nzima ukuyiphatha.
Ukugcinwa kwamanzi: I-HPMC iyaziwa ngeempawu zayo zokugcina amanzi, ezinokunceda ukuthintela ukomisa kwangaphambi kwexesha kunye nokuphucula inkqubo yokufakwa kwesamente kwidaka.Umxholo we-HPMC kufuneka wanele ukugcina umyinge owaneleyo wamanzi, uqinisekisa ukunyangwa okufanelekileyo kunye nokwakhiwa kwebhondi.
Ukubambelela kunye nokuqina kweBond: I-HPMC iphucula ukunamathela kodaka kwii-substrates ezahlukeneyo.Nangona kunjalo, owona mxholo uphezulu we-HPMC kufuneka ulungelelanise phakathi kokuncamathela okwaneleyo kunye nokuncamathela okugqithisileyo, okunokuthi kuthintele ukudibanisa okufanelekileyo okanye kubangele ubunzima ngexesha lokufaka isicelo.
Ukuhambelana nezinye izongezo: Ukwakhiwa kodaka kuhlala kubandakanya ezinye izongezo ezifana ne-air-entraining agents, iplastiki, okanye i-dispersants.Umxholo we-HPMC kufuneka uhambelane nezi zongezo ukuze kuqinisekiswe ukusebenza okuhambelanayo kunye nokuphepha nayiphi na intsebenziswano embi.
Izikhokelo zokumisela umxholo we-HPMC:
Ngelixa umxholo ochanekileyo we-HPMC unokwahluka ngokuxhomekeke kulwakhiwo oluthile lodaka kunye neemfuno zeprojekthi, ezi zikhokelo zilandelayo zinokunceda ukufumanisa esona sixa sifanelekileyo:
Qwalasela Udidi Lodaka: Iindidi ezahlukeneyo zodaka, ezifana neseti ebhityileyo, ibhedi etyebileyo, okanye udaka lokulungisa, zineemfuno ezahlukahlukeneyo zokusebenza, ukuncamathelisa nokugcinwa kwamanzi.Vavanya iimpawu ezithile ezinqwenelekayo zodidi lodaka kwaye ulungelelanise umxholo we-HPMC ngokufanelekileyo.
Ukuqhuba iimvavanyo kunye neebhetshi zoVavanyo: Kucetyiswa ukuba kuqhutywe iimvavanyo kunye neebhetshi zokuvavanya kunye noxinzelelo olwahlukeneyo lwe-HPMC ukuvavanya ukusebenza kodaka.Vavanya izinto ezifana nokusebenza, ukugcinwa kwamanzi, ukunamathela, kunye namandla ukugqiba umxholo we-HPMC ofanelekileyo ohlangabezana neemfuno ezifunekayo.
Jonga kwiiNgcebiso zabavelisi: Abavelisi be-Yibang HPMC babonelela ngezikhokelo okanye iingcebiso zoluhlu olufanelekileyo lwedosi.Ezi ngcebiso zisekelwe kuphando olubanzi kunye novavanyo, kwaye zinokusebenza njengendawo yokuqala eluncedo yokumisela umxholo we-HPMC.
Funa iNgcebiso yobuGcisa: Ukubonisana neengcaphephe ebaleni, njengabameli bobugcisa abasuka kubenzi be-Yibang HPMC okanye amagcisa anamava odaka, anokubonelela ngezimvo ezixabisekileyo kunye neengcebiso malunga nowona mxholo we-HPMC ufanelekileyo kwizicelo ezithile.
Isiphelo:
Ukumisela umxholo ofanelekileyo we-HPMC kudaka kubalulekile ukufezekisa umsebenzi ofunekayo kunye neempawu.Iingqwalasela ezifana nokungaguquguquki, ukugcinwa kwamanzi, ukunamathela, kunye nokuhambelana nezinye izongezo kufuneka zithathelwe ingqalelo xa kumiselwa umxholo ofanelekileyo we-HPMC.Ngokuqhuba ulingo, ngokubhekisa kwizindululo zomenzi weYibang, kunye nokufuna iingcebiso zobungcali, abavelisi beYiba kunye neengcali zokwakha banokuchonga olona luhlu lufanelekileyo lwethamo le-HPMC oluqinisekisa ukusebenza ngokugqibeleleyo, ukuncamathela, kunye nomgangatho wodaka ngokubanzi kwizicelo ezahlukeneyo zokwakha.
