Lisebelisoa tse sa tšoaneng tsa Cellulose Ether ho Lik'hemik'hale Tsa Kaho

Li-cellulose ethers li sebelisoa haholo lik'hemik'hale tsa kaho ka lebaka la thepa ea tsona e fapaneng le mesebetsi. Litšebeliso tse fapaneng tsa li-cellulose ether ho lik'hemik'hale tsa kaho ke tsena:

1. Seretse sa Samente le Gypsum Thehiloeng:

  • Ho Tema le ho Boloka Metsi: Li-cellulose ethers, tse kang Hydroxyethyl Methylcellulose (HEMC) le Hydroxypropyl Methylcellulose (HPMC), li sebelisoa e le lintho tse teteaneng le tse bolokang metsi lireteng tse entsoeng ka samente, li-renders le li-plaster. Li ntlafatsa ts'ebetso, ho khomarela, le ho hanyetsa ho sag, hammoho le ho ntlafatsa nako e bulehileng le taolo ea metsi.

2. Likhomaretsi tsa Lithaele le Li-Grouts:

  • Adhesion and Slip Resistance: Cellulose ethers e sebetsa e le li-binders le li-protection tsa ho khomarela li-adhesives le li-grouts, ho netefatsa maqhama a matla le a tšoarellang pakeng tsa lithaele le li-substrates. Li ntlafatsa ho koloba, ho ata, le ho hanyetsa ho sag, hammoho le ho matlafatsa ho hanyetsa ho thella le ho holofala.

3. Metsoako ea Boiketlo:

  • Phallo le Tšisinyeho ea Bokahohle: Li-ether tsa cellulose li sebelisoa e le li-flood modifiers le lisebelisoa tse fokotsang tsitsipano holim'a metsoako ea ho ikemela, e matlafatsang phallo le thepa ea ho leka-lekanya. Li ntlafatsa boreleli ba holim'a metsi, ho koloba ha substrate, le ho lokolloa ha moea, hammoho le ho fokotsa bofokoli le likoti.

4. Litsamaiso tsa Kantle tsa Insulation le Finish Systems (EIFS):

  • Ho hanyetsa Boemo ba Boemo ba Leholimo le ho Tšoareha: Li-cellulose ethers li fana ka khanyetso ea boemo ba leholimo le ho tšoarella ho li-insulation tsa ka ntle le ho qeta (EIFS), li sireletsa khahlanong le ho kenella ha mongobo, mahlaseli a UV le ho senyeha ha tikoloho. Li ntlafatsa ho hanyetsa ha crack, ho khomarela, le ho tenyetseha, hammoho le ho matlafatsa botsitso ba mebala le ho qeta holimo.

5. Likarolo tse Thibela Metsi:

  • Ho Fetolana le ho Hanela Metsi: Li-cellulose ether li sebelisoa e le li-addifiers lirapeng tse thibelang metsi, li ntlafatsa ho tenyetseha, ho hanyetsa metsi, le bokhoni ba ho koala bridging. Li matlafatsa ho khomarela li-substrates, hape li fana ka khanyetso khatellong ea hydrostatic, tlhaselo ea lik'hemik'hale, le potoloho ea ho qhibiliha ha leqhoa.

6. Lisebelisuoa tsa Tokiso le Tsosoloso:

  • Botšepehi ba Sebopeho le Tlamahano: Li-ether tsa cellulose li ntlafatsa botšepehi ba sebopeho le tlamahano ea thepa ea ho lokisa le ea tsosoloso, e kang lirafshoa tsa ho lokisa konkreite le li-grouts. Li ntlafatsa ho sebetsa, ho khomarela le ho tšoarella, hammoho le ho fana ka tšireletso khahlanong le carbonation, chloride ingress, le corrosion.

7. Metsoako e Kopanetsoeng le Li-Sealants:

  • Ho khomarela le ho Kopana: Li-cellulose ethers li sebetsa e le li-binders le li-rheology modifiers ka metsoako e kopantsoeng le li-sealants, ho netefatsa ho khomarela ka matla le ho kopana pakeng tsa libaka tse kopanetsoeng. Li ntlafatsa ts'ebetso, ho ata, le lehlabathe, hammoho le ho fokotsa ho honyela, ho peperana le phofo.

8. Liaparo tse Thibela mollo:

  • Thermal Insulation le Fire Resistance: Cellulose ethers e ntlafatsa ho thibela mocheso le ho hanyetsa mollo oa liphahlo tse thibelang mollo, ho fana ka tšireletso khahlanong le ho fetisetsa mocheso le ho ata ha lelakabe. Li ntlafatsa intumescence, char formation, le ho khomarela, hammoho le ho fokotsa tlhahiso ea mosi le chefo.

9. Keketso ea Tlhahiso (3D Printing):

  • Viscosity le Layer Adhesion: Cellulose ethers li sebelisoa e le li-viscosity modifiers le li-binder system mekhoeng ea tlhahiso ea tlatsetso, joalo ka khatiso ea 3D ea thepa ea kaho. Li ntlafatsa phallo, ho hatisoa, le ho khomarela lera, hammoho le ho etsa hore ho behoe ka nepo le ho nepahala ha sebopeho.

Qetello:

Li-cellulose ethers li bapala karolo ea bohlokoa lik'hemik'haleng tse fapaneng tsa kaho, li kenya letsoho ntlafatsong ea ts'ebetso, ho tšoarella le ho tšoarella ha thepa ea kaho le lits'ebetso. Mehaho ea bona e feto-fetohang e ba etsa litlatsetso tsa bohlokoa bakeng sa ho ntlafatsa ts'ebetso, ho khomarela, ho hanyetsa metsi, boemo ba leholimo le ho hanyetsa mollo lits'ebetsong tse fapaneng tsa kaho.
