Mokhahlelo oa ho ahacellulose etherke tlatsetso ea bohlokoa ea ho haha 'me e sebelisoa haholo mererong ea kaho. E hlahisoa haholo ke phetoho ea lik'hemik'hale ea selulose ka har'a likhoele tsa semela mme e na le litšobotsi tsa metsoako e phahameng ea boima ba limolek'hule. Mohaho oa cellulose ether o sebelisoa haholo-holo ho thepa ea mohaho e kang samente, seretse, ho roala, seretse se omeletseng, joalo-joalo, se ka ntlafatsang ts'ebetso ea lisebelisoa tsena tsa mohaho le ho ntlafatsa ts'ebeliso ea tsona.
1. Ho tiisa le ho boloka metsi a seretse sa samente
Ka seretse sa samente, cellulose ether, e le setsi sa ho thibela metsi le ho boloka metsi, se ka ntlafatsa ka katleho ho sebetsa le ho tšoarella ha seretse. E fokotsa mouoane oa metsi ka ho etsa filimi e nang le hydrated, e ntlafatsa ho boloka metsi a seretse, 'me e liehe lebelo la ho arabela ha hydration ea samente, kahoo e ntlafatsa ho sebetsa ha seretse sa samente le ho etsa bonnete ba hore seretse se boloka ho sebetsa ho loketseng nako e telele. Haholo-holo mocheso o phahameng kapa tikoloho e omileng, seretse sa samente se atisa ho lahleheloa ke metsi. Ho eketsoa ha cellulose ether ho ka liehisa tahlehelo ea metsi haholo, ho fokotsa ho phatloha, le ho netefatsa boleng ba kaho.
2. Kopo ea seretse se omileng
Seretse se omileng (ho kenyeletsoa phofo ea putty, sekhomaretsi sa lithaele, seretse sa plaster, joalo-joalo) ke lisebelisoa tse sebelisoang haholo kahong ea sejoale-joale, 'me tšebeliso ea cellulose ether e bohlokoa. Cellulose ether e ka ntlafatsa mokelikeli, ho boloka metsi le ho khomarela seretse se omileng, ho etsa hore ho be bonolo ho aha. E ka ntlafatsa ts'ebetso ea seretse se omileng, ea fokotsa stratification, 'me ea ntlafatsa ho khomarela le matla a seretse, kahoo ea ntlafatsa katleho ea kaho le phello ea tšebeliso. Ho feta moo, cellulose ether e ka thibela seretse se omileng hore se se ke sa kopana nakong ea polokelo le lipalangoang.
3. Ntlafatso ea ts'ebetso ea marako a marako
Liaparo tsa meralo ke lisebelisoa tsa bohlokoa bakeng sa mokhabiso oa mohaho. Cellulose ether, e le motenya, e ka ntlafatsa thepa ea rheological ea ho roala, ho etsa hore ho be bonolo ho sebelisa lesela nakong ea kaho le ho fokotsa ho rotha. E boetse e na le ho boloka metsi hantle, e thusang ho ntlafatsa ho hanyetsa metsi, ho tšoarella le ts'ebetso ea kaho ea ho roala. Ho eketsoa ha cellulose ether ho ka matlafatsa botenya le ho khomarela ho roala, haholo-holo ka liaparo tse ling tsa boleng bo phahameng ba bokantle ba lerako, ho ka ntlafatsa haholo botsitso le boreleli ba ho roala le ho qoba ho senya le ho tšolloa ha seaparo.
4. Ntlafatsa ho khomarela thepa ea mohaho
Kaho-grade cellulose ethers phetha karolo ea ho ntlafatsa ho khomarela ba bang ba thepa e khethehileng ea ho haha, haholo-holo ka sekgomaretsi lithaele, gypsum phofo, likhomaretsi, joalo-joalo Cellulose ethers ke ke feela ho ntlafatsa ho khomarela qalong ea thepa ena, empa hape ho eketsa nako ea bona e bulehileng ho netefatsa hore ho na le nako e lekaneng ea ho lokisa nakong ea ts'ebetso ea kaho. Ka nako e ts'oanang, li-cellulose ethers li ka boela tsa ntlafatsa ho thella ha lisebelisoa tsena, ho etsa hore mokhoa oa kaho o be bonolo le ho ntlafatsa katleho ea kaho le boleng ba thepa.
5. Kopo ka konkreite ea precast
Li-cellulose ethers le tsona li phetha karolo ea bohlokoa tlhahisong ea lihlahisoa tsa konkreite tse entsoeng esale pele. E ka eketsa ts'ebetso ea konkreite, e etsa hore ho be bonolo ho tšollela le ho etsa sebopeho. Li-cellulose ethers li ka ntlafatsa ho phalla ha metsi, ho khomarela le ho boloka metsi a konkreite, le ho qoba mathata a kang ho tsoa mali le ho arohana nakong ea ho tšela konkreite. Ntle le moo, li-cellulose ethers li ka ntlafatsa boreleli ba bokaholimo le ho hanyetsa mapheo a konkreite, 'me tsa ntlafatsa matla le ho tšoarella ha konkreite ea precast.
6. Ntlafatso ea ts'ebetso ea lisebelisoa tsa mohaho tse thehiloeng ho gypsum
Gypsum, e le thepa ea kaho e sebelisoang hangata, e sebelisoa haholo mererong ea ho lipola le siling. Joaloka moemeli oa ho thibela metsi le ho boloka metsi, kaho-grade cellulose ether e ka ntlafatsa haholo ts'ebetso le thepa ea kaho ea gypsum. E ka eketsa bokhoni ba ho boloka metsi ba gypsum le ho thibela gypsum hore e se ke ea thatafala pele ho nako ka lebaka la mouoane o potlakileng oa metsi nakong ea mosebetsi oa kaho. Cellulose ether e ka boela ea ntlafatsa ho hanyetsa ha gypsum, ho etsa hore thepa ea mohaho e thehiloeng ho gypsum e be e tsitsitseng le e tšoarellang, e fokotsa ho phunyeha le ho netefatsa phello ea kaho.
7. Kopo ka thepa e sa keneleng metsi
Cellulose ether e ka boela ea sebelisoa ho haha lisebelisoa tse sa keneleng metsi ho ntlafatsa boleng ba tsona ba ho khomarela le ho haha. Lisebelisoa tse sa keneleng metsi ka kakaretso li na le viscosity e phahameng. Ho eketsoa ha cellulose ether ho ka ntlafatsa thepa ea bona ea kaho, ho etsa hore kopo e be e ts'oanang haholoanyane, 'me e qobe ho tšolloa le ho phunyeha ha seaparo. Ho phaella moo, cellulose ether e ka boela ea ntlafatsa ho khomarela lisebelisoa tse sa keneleng metsi, ho ntlafatsa ho khomarela pakeng tsa lera le sa keneleng metsi le lera la motheo, ho thibela ho kenella ha metsi, le ho ntlafatsa phello ea metsi ea mohaho.
Mokhahlelo oa kahocellulose ethere sebelisoa haholo indastering ea kaho, 'me thepa ea eona e ikhethang ea' mele le ea lik'hemik'hale e etsa hore e be tlatsetso e hlokahalang thepa ea kaho. E ke ke ea ntlafatsa feela ts'ebetso ea kaho ea thepa ea mohaho, ho ntlafatsa ho khomarela, ho boloka metsi le botsitso ba thepa, empa hape ho ntlafatsa ho tšoarella le boleng ba lihlahisoa tsa mohaho. Ka tlhokahalo e ntseng e eketseha ea lisebelisoa tsa mohaho tse sebetsang hantle indastering ea kaho, litebello tsa ts'ebeliso ea li-cellulose ether tsa boemo ba kaho li tla ba tse pharaletseng nakong e tlang.
