Tšebeliso ea li-cellulose ethers ka har'a metsi ka har'a metsi

Joalo ka thepa e sebetsang ka bongata le e baballang tikoloho, cellulose ether e sebelisitsoe haholo mafapheng a fapaneng joalo ka indasteri ea kaho, indasteri ea lijo, indasteri ea meriana le indasteri ea masela. Har'a tsona, cellulose ether e hohetse tlhokomelo e eketsehileng bakeng sa ts'ebeliso ea eona ka har'a mebala ea metsi ka metsing ka lebaka la thepa ea eona e ikhethang e kang ho qhibiliha ha metsi, ho se chefo le ho senyeha ha lintho.

Thepa ea cellulose ethers

Li-cellulose ethers li nkiloe ho cellulose, polymer ea tlhaho e ngata ka ho fetisisa le e nchafalitsoeng lefatšeng. Li qhibiliha ka metsing, ha li na ionic, ha li chefo ebile lia senyeha, 'me li etsa hore e be khetho e ntle bakeng sa lits'ebetso tse ngata.

Mefuta e atileng haholo ea li-cellulose ethers tse sebelisoang ho koaheloa ka mebala ea metsi ka metsing li kenyelletsa hydroxyethyl cellulose (HEC), methyl cellulose (MC), le carboxymethyl cellulose (CMC). Li-cellulose ethers tsena li na le thepa e sa tšoaneng, empa kaofela li na le thepa e babatsehang ea ho tiisa, ho tlama le ho boloka metsi, e leng se etsang hore e be se loketseng bakeng sa ho sebelisoa ka har'a metsi a nang le mebala ea metsi.

Melemo ea ho sebelisa li-cellulose ethers ka har'a metsi a nang le 'mala oa metsi

- Botsitso bo ntlafetseng: E ​​'ngoe ea melemo ea bohlokoa ea ho sebelisa li-cellulose ethers ka har'a metsi a nang le mebala ea metsi ka metsing ke ho eketseha ha botsitso ba liaparo. Li-cellulose ethers li thusa ho thibela likaroloana tsa pigment hore li se ke tsa lula tlase ho tanka ka ho li emisa ka metsing.

- Viscosity e phahameng: Cellulose ethers e ka eketsa viscosity ea pente, ea etsa hore e be motenya le ho phutholoha ho e sebelisa. Li boetse li thusa pente hore e be boreleli, esita le ho roala holim'a metsi, ho ntlafatsa boleng ba pente.

- Ho boloka metsi: Li-cellulose ethers li thusa pente ho boloka mongobo, ho e thibela ho omella kapele. Sena se lumella pente hore e lule e sebelisoa nako e telele, e fa mosebedisi nako e lekaneng ea ho penta holimo.

- Ho lumellana: Li-cellulose ethers li lumellana le lisebelisoa tse ling tse fapaneng tse atisang ho sebelisoa ka har'a metsi ka metsing a koahetsoeng ka mebala, joalo ka li-formers tsa lifilimi, li-defoamers le li-preservatives.

- E Sekehela Tikoloho: Li-cellulose ethers ke lintho tse nkiloeng ka tlhaho le tse senyehang habonolo, e leng se etsang hore e be khetho e ntle ea tikoloho bakeng sa ho roala metsi ka har'a metsi.

Tšebeliso e ka bang teng ea li-cellulose ethers ka har'a litlolo tsa 'mala oa metsi ka metsing

- Mabota a ka hare le siling: Liaparo tse mebala-bala tse nang le metsi ka metsing tse nang le li-cellulose ethers li ka sebelisoa marakong a ka hare le lisiling malapeng, liofising le libakeng tse ling tse ka hare. Matla a eona a ntlafalitsoeng a botsitso le ho boloka metsi a etsa hore e be sebaka se loketseng ho sebelisoa libakeng tse mongobo o mongata joalo ka liapehelo le liphaposi tsa ho hlapela.

- Mabota a ka ntle: Li-cellulose ethers li ka boela tsa sebelisoa ka har'a metsi a metsi a mebala-bala bakeng sa marako a ka ntle. Ba thusa ho penta ho khomarela holimo holimo le ho fana ka qetello e tšoarellang le e tšoarellang nako e telele.

- Bonono bo Botle: Li-cellulose ethers li ka sebelisoa mesebetsing ea bonono ho sebelisa mebala ea 'mala oa metsi ka metsing, joalo ka li-watercolor. Lintho tsa bona tse phahameng tsa viscosity le ho boloka metsi li lumella lipente ho ata le ho tsoakana habonolo pampiring, ho etsa mebala e metle le e hlakileng.

ha re phethela

Li-cellulose ethers ke lisebelisoa tse babatsehang bakeng sa ho roala ka mebala ea metsi ka metsing ka lebaka la thepa ea bona e ikhethang ea ho qhibiliha ha metsi, ho se chefo le ho senyeha ha lintho. Li ntlafatsa botsitso, viscosity, ho boloka metsi le ho lumellana ha lipente, ho etsa hore ho be bonolo ho li sebelisa le ho fana ka boleng bo botle ba pente.

Ka hona, li-cellulose ethers li na le bokhoni bo boholo lits'ebetsong tse fapaneng tse kang marako a ka hare, marako a ka ntle le bonono bo botle. Tšebeliso ea li-cellulose ethers ka mebala ea metsi ka metsing e fa basebelisi khetho e ntle ea tikoloho le ea boleng bo phahameng eo ka sebele e tla fana ka liphello tse hlaheletseng.
