Ether ea starche sebelisoa haholo-holo ka seretse sa kaho, se ka amang ho tsitsa ha seretse se thehiloeng ho gypsum, samente le kalaka, le ho fetola kaho le ho hanyetsa sag ea seretse. Hangata li-ether tsa starch li sebelisoa hammoho le li-cellulose ethers tse sa fetoloang le tse fetotsoeng. E loketse mekhoa ea bobeli e sa nke lehlakore le ea alkaline, 'me e lumellana le lisebelisoa tse ngata tsa gypsum le lihlahisoa tsa samente (tse kang li-surfactants, MC, starch le polyvinyl acetate le li-polymer tse ling tse qhibilihisang metsi).
Litšobotsi tsa starch ether haholo-holo li ka ho:
(1) Ntlafatsa khanyetso ea sag;
(2) Ntlafatsa mokhoa oa ho haha;
(3) Kotulo e phahameng ea seretse.
Mosebetsi o ka sehloohong oa starch ether ka seretse se omeletseng se thehiloeng ho gypsum ke sefe?
Starch ether ke e 'ngoe ea li-additives tse ka sehloohong tsa seretse sa phofo se omeletseng. E ka lumellana le li-additives tse ling. E sebelisoa haholo ho li-adhesives tsa lithaele, lirekere tsa ho lokisa, gypsum ea plastering, putty e ka hare le e ka ntle ea lerako, lisebelisoa tse entsoeng ka gypsum-based caulking le ho tlatsa, li-interface agents, masonry In mortars, e boetse e loketse ho sebelisoa ka letsoho kapa ho fafatsa ka samente-based kapa gypsum. -e thehiloeng seretse. E sebetsa ka tsela e latelang:
(1) Hangata starch ether 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 sag le khanyetso ea ho thella ha seretse, ka boleng bo phahameng ba chai.
(2) Ho eketsa tekanyo e loketseng ea starch ether seretseng se nang le methyl cellulose ether ho ka eketsa haholo ho tsitsisa ha seretse, ho ntlafatsa mokelikeli, le ho etsa hore mohaho o be bonolo le o boreleli.
(3) Ho eketsa tekanyo e loketseng ea starch ether seretseng se nang le methyl cellulose ether ho ka eketsa ho boloka metsi a seretse le ho lelefatsa nako e bulehileng.
Melemo ea ts'ebeliso le mekhoa ea ho boloka starch ether ke efe?
E ka sebelisoa e le motsoako oa lihlahisoa tse thehiloeng ho samente, lihlahisoa tse thehiloeng ho gypsum le lihlahisoa tsa ash-calcium.
(1) Melemo le lisebelisoa:
a. E na le phello e teteaneng holim'a seretse, e ka teteana ka potlako, 'me e na le lubricity e ntle;
b. Tekanyo e nyane, mme tekanyo e tlase haholo e ka fihlela phello e phahameng;
c. Ntlafatsa bokhoni ba anti-slide ba seretse se tlanngoeng;
d. eketsa nako e bulehileng ea thepa;
e. Ntlafatsa ts'ebetso ea ts'ebetso ea lisebelisoa le ho etsa hore ts'ebetso e be bonolo.
(2) Polokelo:
Sehlahiswa se hlaseleha habonolo ke mongobo mme se tlameha ho bolokoa sebakeng se omeletseng le se phodileng ka har'a sephutheloana sa pele. Ho molemo ho e sebelisa nakong ea likhoeli tse 12. (E khothaletsoa ho sebelisoa hammoho le high-viscosity cellulose ether, 'me karolelano e akaretsang ea cellulose ether ho starch ether ke 7:3~8:2)
