Kereiti ea thepa ea kahocellulose etherke motsoako oa bohlokoa o sebetsang oa lik'hemik'hale, o sebelisoang haholo ho thepa ea mohaho, e kang samente, konkreite, seretse se omileng, joalo-joalo.
1. Sebopeho sa lik'hemik'hale le lihlopha
Cellulose ether ke motsoako oa polymer o entsoeng ka phetoho ea lik'hemik'hale ea cellulose ea tlhaho. Karolo ea eona e ka sehloohong ke sehlopha sa hydroxyl sa cellulose se fetotsoeng ke moemeli oa etherifying (joalo ka vinyl chloride, acetic acid, joalo-joalo). Ho ea ka lihlopha tse fapaneng tsa etherifying, e ka aroloa ka mefuta e fapaneng ea li-cellulose ethers, haholo-holo ho kenyelletsa hydroxypropyl methylcellulose (HPMC), hydroxyethyl cellulose (HEC) le methyl cellulose (MC).
2. Ho boloka metsi
Lisebelisuoa tsa kaho tsa sehlopha sa cellulose ether li na le thepa e ntle ea ho boloka metsi, e ka ntlafatsang ka nepo matla a ho boloka metsi a seretse le konkreite. Sena se matlafatsa ts'ebetso ea lisebelisoa nakong ea kaho mme se fokotsa ho phatloha le tahlehelo ea matla e bakoang ke mouoane oa metsi.
3. Ho teteana
Cellulose ether e na le thepa e ntle ea thickening, e ka ntlafatsang metsi le viscosity ea thepa ea mohaho, ho etsa hore ho be bonolo ho sebetsa nakong ea kaho. Thickening thusa ho ntlafatsa botsitso ba lintho tse bonahalang le ho thibela stratification le sedimentation.
4. Phokotso ea metsi
Ho isa tekanyong e itseng,li-cellulose etherse ka fokotsa bongata ba metsi ka konkreite kapa seretse, kahoo e ntlafatsa matla le ho tšoarella ha thepa. Tšobotsi ena e etsa hore e be ea bohlokoa ka ho khetheha ts'ebetsong ea konkreite e sebetsang hantle.
5. Ts'ebetso ea kaho
Lisebelisoa tsa ho haha tse nang le cellulose ethers li na le ts'ebetso e ntle nakong ea kaho, e ka eketsang nako ea kaho le ho fokotsa mathata a kaho a bakoang ke ho omisa. Ho feta moo, ba ka boela ba ntlafatsa ho khomarela seretse le ho ntlafatsa ho khomarela thepa ea ho roala.
6. Crack resistance
Li-cellulose ethers li ka ntlafatsa ho hanyetsa ha mapetsong a seretse le konkreite le ho fokotsa mapetsong a bakoang ke ho fetoha ha mocheso kapa ho honyela ho omisang. Sena se bohlokoa bakeng sa botsitso ba nako e telele le botle ba meaho.
7. Ho ikamahanya le maemo le ho lumellana
Li-cellulose ethers tsa boemo ba thepa ea mohaho li lumellana hantle le mefuta e sa tšoaneng ea thepa ea mohaho 'me li ka kopanngoa le samente, gypsum, polymers le lisebelisoa tse ling ntle le ho ama ts'ebetso ea tsona. Ho ikamahanya le maemo ho etsa hore li-ether tsa cellulose li sebelisoe haholo indastering ea kaho.
8. Tšireletso ea tikoloho
Kaha thepa e tala eali-cellulose ethersli tsoa ho likhoele tsa limela, tsona ka botsona li na le litšobotsi tse itseng tsa tšireletso ea tikoloho. Ha ho bapisoa le li-polymer tse ling tsa maiketsetso, cellulose ether e baballa tikoloho ha e sebelisoa le ho hloekisa litšila.
9. Libaka tsa kopo
Moaho oa mofuta oa cellulose ether o sebelisoa haholo mefuteng e fapaneng ea thepa ea moaho, ho kenyelletsa:
Seretse se omileng: joalo ka seretse se tlamang, seretse sa plaster, joalo-joalo.
Konkreite: haholo-holo konkreite e sebetsang hantle.
Ho roala: ho ka sebelisoa bakeng sa masela a ka hare le a ka ntle a marako, pente ea latex, joalo-joalo.
Lihlahisoa tsa Gypsum: tse kang gypsum board le gypsum putty.
10. Litlhokomelo bakeng sa tšebeliso
Ha u sebelisa thepa ea moaho cellulose ether, u lokela ho ela hloko lintlha tse latelang:
Eketsa ho ea ka karo-karolelano e khothalletsoang, ho feteletseng kapa ho sa lekaneng ho tla ama ts'ebetso ea ho qetela.
Etsa bonnete ba ho tšoana nakong ea ho kopanya ho qoba agglomeration.
Ha u boloka, ela hloko bopaki ba mongobo ho qoba mongobo le agglomeration.
Moaho oa boleng ba cellulose ether e se e le tlatsetso ea bohlokoa indastering ea thepa ea moaho ka lebaka la thepa ea eona e ikhethang le ts'ebeliso e pharaletseng. Ka ntlafatso e tsoelang pele ea litlhoko tsa indasteri ea kaho bakeng sa ts'ebetso ea thepa, menyetla ea ts'ebeliso ea cellulose ether e tla ba e pharaletseng.
