Hydroxypropyl methylcellulose (HPMC) ke tlatsetso e sebelisoang hangata ha ho etsoa seretse, e fana ka thepa ea bohlokoa joalo ka ts'ebetso e ntlafalitsoeng, ho khomarela le ho boloka metsi.Leha ho le joalo, ho fumana palo e nepahetseng ea HPMC ho e kenyelletsa ts'ebetsong ea ho etsa seretse ho bohlokoa ho fihlela ts'ebetso e nepahetseng.
Lintlha tse Amang litaba tsa HPMC ka Seretseng:
Ho na le lintlha tse 'maloa tse lokelang ho nahanoa ha ho khethoa HPMC e nepahetseng ka har'a seretse:
Tšebelisano e Lakatsehang: Litaba tsa HPMC li ama haholo ho tsitsa le ho sebetsa ha seretse.Maemo a phahameng a HPMC hangata a hlahisa metsoako e mengata ea polasetiki le e momahaneng, e ntlafatsang ts'ebeliso.Leha ho le joalo, litaba tsa HPMC tse feteletseng li ka lebisa ho seretse se khomarelang kapa sa "botoro", se etsa hore ho be thata ho sebetsana le sona.
Ho boloka Metsi: HPMC e tsejoa ka thepa ea eona ea ho boloka metsi, e ka thusang ho thibela ho omisa pele ho nako le ho ntlafatsa ts'ebetso ea hydration ea samente ka seretse.Likahare tsa HPMC li lokela ho lekana ho boloka palo e lekaneng ea metsi, ho netefatsa pheko e nepahetseng le ho theha bond.
Ho khomarela le Matla a Bond: HPMC e ntlafatsa ho khomarela seretse ho li-substrates tse fapaneng.Leha ho le joalo, litaba tsa HPMC tse nepahetseng li lokela ho ba le botsitso lipakeng tsa ho khomarela ho lekaneng le ho khomarela ho feteletseng, tse ka sitisang tlamahano e nepahetseng kapa tsa baka mathata nakong ea kopo.
Ho lumellana le Li-additives tse ling: Metsoako ea seretse hangata e kenyelletsa li-additives tse ling tse kang li-air-entraining agents, plasticizers, kapa dispersants.Litaba tsa HPMC li tlameha ho lumellana le li-additives tsena ho netefatsa ts'ebetso e tsitsitseng le ho qoba litšebelisano tse mpe.
Litaelo tsa ho khetholla litaba tsa HPMC:
Leha litaba tse nepahetseng tsa HPMC li ka fapana ho ipapisitsoe le litlhophiso tse khethehileng tsa seretse le litlhoko tsa projeke, litataiso tse latelang li ka thusa ho fumana chelete e nepahetseng haholo:
Nahana ka Mofuta oa Seretse: Mefuta e fapaneng ea seretse, e kang seretse se tšesaane, se teteaneng, kapa seretse sa ho lokisa, se na le litlhoko tse sa tšoaneng bakeng sa ho sebetsa, ho khomarela le ho boloka metsi.Lekola litšobotsi tse khethehileng tse lakatsehang bakeng sa mofuta oa seretse 'me u fetole litaba tsa HPMC ka nepo.
Etsa Liteko le Lihlopha tsa Teko: Ho khothaletsoa ho etsa liteko le lihlopha tsa liteko tse nang le maemo a fapaneng a HPMC ho lekola ts'ebetso ea seretse.Lekola lintlha tse kang ho sebetsa, ho boloka metsi, ho khomarela, le matla ho fumana hore na litaba tsa HPMC tse nepahetseng ka ho fetisisa li finyella litlhoko tse lakatsehang hantle.
Sheba Litlhahiso tsa Baetsi: Baetsi ba Yibang HPMC hangata ba fana ka litataiso kapa likhothaletso bakeng sa mofuta o nepahetseng oa litekanyetso.Litlhahiso tsena li ipapisitse le lipatlisiso le liteko tse batsi, 'me li ka sebetsa e le sebaka sa bohlokoa sa ho qala ho tseba litaba tsa HPMC.
Batla Keletso ea Setsebi: Ho buisana le litsebi lefapheng lena, joalo ka baemeli ba tekheniki ho tsoa ho baetsi ba Yibang HPMC kapa litsebi tse nang le boiphihlelo tsa seretse, li ka fana ka leseli le likhothaletso mabapi le litaba tse nepahetseng tsa HPMC bakeng sa lits'ebetso tse ikhethileng.
Qetello:
Ho khetholla litaba tse nepahetseng tsa HPMC ka seretse ho bohlokoa ho fihlela ts'ebetso le thepa e lakatsehang.Menahano e joalo ka botsitso, ho boloka metsi, ho khomarela, le ho tsamaellana le litlatsetso tse ling li lokela ho nahanoa ha ho khethoa litaba tse nepahetseng tsa HPMC.Ka ho etsa liteko, ho bua ka likhothaletso tsa moetsi oa Yibang, le ho batla boeletsi ba litsebi, bahlahisi ba Yibang le litsebi tsa kaho ba ka tseba mefuta e nepahetseng ka ho fetisisa ea litekanyetso tsa HPMC e tiisang hore ho sebetsa hantle, ho khomarela le boleng ba seretse ka kakaretso lits'ebetsong tse fapaneng tsa kaho.
