(1) Bokhoni bo botle ba ho tiisa ka potlako: viscosity e bohareng, ho boloka metsi a mangata;
(2) Tekanyetso e nyenyane, 'me tekanyo e tlaase e ka ba le phello e ntle;
(3) Ntlafatsa bokhoni ba anti-sag ba thepa ka boeona;
(4) E na le lubricity e ntle, e ka ntlafatsang ts'ebetso ea lisebelisoa le ho etsa hore ts'ebetso e be bonolo.
Me na le likarolo
Litšobotsi tsa starch ether haholo-holo li ka ho:
(a) Ntlafatsa khanyetso ea sag;
(b) Ntlafatsa mokhoa oa ho aha;
(c) Ntlafatsa sekhahla sa ho boloka metsi a seretse.
Synergy
Hangata ether ea starch e sebelisoa hammoho le methyl cellulose ether, e bontšang phello e ntle ea synergistic pakeng tsa tse peli.Ho eketsa tekanyo e loketseng ea starch ether ho methyl cellulose ether ho ka ntlafatsa haholo ho hanyetsa ha sag le ho hanyetsa ho thella ha seretse.Boleng bo phahameng ba lihlahisoa.
Ka seretse se nang le methyl cellulose ether, ho eketsa tekanyo e loketseng ea starch ether ho ka eketsa haholo ho tsitsisa ha seretse le ho ntlafatsa metsi, ho etsa hore mohaho o be bonolo le ho senya.
Ka seretse se nang le methyl cellulose ether, ho eketsa tekanyo e loketseng ea starch ether ho ka eketsa ho boloka metsi a seretse le ho lelefatsa nako e bulehileng.
Starch ether ke starch ether e fetotsoeng ka lik'hemik'hale e qhibilihang ka metsing, e tsamaellanang le li-additives tse ling ka har'a seretse sa phofo se omeletseng, se sebelisoang haholo ho likhomaretsi tsa lithaele, seretse sa ho lokisa, plaster ea plaster, putty ea bokahare le bokantle ba lebota, lisebelisoa tsa gypsum-based caulking and filling Materials, li-interface agents, seretse sa masonry.
Starch ether e loketse mefuta eohle ea (samente, gypsum, lime calcium-based) ka hare le bokantle ba lebota putty, le mefuta e sa tšoaneng ea ho tobana le seretse plastering seretse.
E ka sebelisoa e le motsoako oa lihlahisoa tse thehiloeng ho samente, lihlahisoa tse thehiloeng ho gypsum le lihlahisoa tsa lime-calcium.Starch ether e lumellana hantle le meaho e meng le li-admixtures;e loketse bakeng sa ho haha metsoako e omileng e kang seretse, li-adhesives, plastering le lisebelisoa tsa ho roala.Starch ether le methyl cellulose ether (KimaCellMC grade) li sebelisoa hammoho kahong ea metsoako e omileng ho fana ka matla a holimo, sebopeho se matla, ho hanyetsa sag le boiketlo ba ho sebetsana.The viscosity ea seretse, likhomaretsi, plasters le roll renders tse nang le methyl cellulose ethers e phahameng e ka fokotsoa ka ho eketsoa ha starch ethers.
