Ho ntlafatsa Dry Mortar ka HPS Admixture
Li-ether tsa starch, joalo ka hydroxypropyl starch ether(HPS), le tsona li ka sebelisoa e le metsoako ho matlafatsa metsoako ea seretse se omeletseng. Mona ke kamoo li-admixtures tsa starch ether li ka ntlafatsang seretse se omileng:
- Ho Boloka Metsi: Metsoako ea starch ether e ntlafatsa ho bolokoa ha metsi ka har'a seretse se omileng, se ts'oanang le HPMC. Thepa ena e thusa ho thibela ho omisoa pele ho nako ea motsoako oa seretse, ho netefatsa nako e telele ea ho sebetsa le ho ntlafatsa ts'ebetso.
- Ho sebetsa le ho ata: Li-ether tsa starch li sebetsa e le liphetoho tsa rheology, li matlafatsa ts'ebetso le ho ata ha metsoako ea seretse se omeletseng. Li thusa seretse ho phalla hantle nakong ea ts'ebeliso ha se ntse se boloka botsitso le ho thibela ho theoha kapa ho thella.
- Ho khomarela: Metsoako ea starch ether e ka ntlafatsa ho khomarela ha seretse se omeletseng ho li-substrates tse fapa-fapaneng, ho khothalletsa ho kolobisa hamolemo le ho tlamahana pakeng tsa seretse le substrate. Sena se fella ka ho khomarela ho matla le ho tšoarella, haholo-holo maemong a thata a kopo.
- Ho Fokotsa Shrinkage: Ka ho ntlafatsa ho boloka metsi le ho tsitsisa ka kakaretso, starch ethers e thusa ho fokotsa ho fokotseha nakong ea ho phekola seretse se omileng. Sena se lebisa ho fokotseng ho phunyeha le ho ntlafatsa matla a tlamahano, e leng se etsang hore ho be le manonyeletso a mangata a tšepahalang le a tšoarellang nako e telele.
- Flexural Strength: Starch ethers e ka kenya letsoho ho matla a feto-fetohang a metsoako ea seretse se omeletseng, e leng se etsang hore e se ke ea hlola e e-ba khahlanong le ho senya le ho senyeha ha mohaho. Thepa ena e na le molemo lits'ebetsong moo seretse se nang le matla a ho kobeha kapa a fetohang.
- Ho Khanyetso le Lintlha tsa Tikoloho: Metsoako ea seretse se omeletseng se matlafalitsoeng ka li-starch ethers li ka bonts'a khanyetso e ntlafalitsoeng khahlanong le maemo a tikoloho joalo ka liphetoho tsa mocheso, mongobo le potoloho ea leqhoa. Sena se tiisa ts'ebetso ea nako e telele le botsitso maemong a fapaneng a leholimo.
- Ho tšoarella nako e telele: Metsoako ea starch ether e ka ntlafatsa ho tšoarella ha seretse se omileng ka ho ntlafatsa ho hanyetsa ho khathala, ho khojoa le ho pepesehela lik'hemik'hale. Sena se fella ka manonyeletso a seretse a tšoarellang nako e telele le litlhoko tse fokotsehileng tsa tlhokomelo ha nako e ntse e ea.
- Ho lumellana le Li-additives tse ling: Li-ether tsa starch li lumellana le mefuta e mengata ea li-additives tse atisang ho sebelisoa ha ho etsoa seretse se omeletseng, se lumellang ho feto-fetoha ha sebopeho le ho nolofalletsa ho iketsetsa metsoako ea seretse ho finyella litlhoko tse khethehileng tsa tshebetso.
Ho bohlokoa ho hlokomela hore leha li-starch ethers li fana ka melemo e ts'oanang ho HPMC mabapi le ho boloka metsi le ntlafatso ea ts'ebetso, litšoaneleho tsa bona tsa ts'ebetso le maemo a nepahetseng a litekanyetso li ka fapana. Baetsi ba lokela ho etsa liteko le ho ntlafatsa ka botlalo ho fumana motsoako oa starch ether o loketseng ka ho fetesisa le moetso bakeng sa litlhoko tse ikhethang tsa kopo ea bona. Ho feta moo, ho sebelisana 'moho le barekisi ba nang le boiphihlelo kapa baetsi ba liforomo ho ka fana ka leseli le ts'ehetso ea tekheniki mabapi le ho ntlafatsa metsoako ea seretse se ommeng ka li-admixtures tsa starch ether.
