Li-cellulose ethers tse sebelisoang ka har'a sekhomaretsi sa latex

Selelekela:

Likhomaretsi tse thehiloeng ho latex li sebelisoa haholo liindastering tse fapaneng ka lebaka la ho feto-fetoha ha tsona, matla a tlamahano, le botsoalle ba tikoloho. Likhomaretsi tsena li na le ho hasana ha likaroloana tsa polymer ka metsing, 'me latex e le eona karolo ea mantlha. Leha ho le joalo, ho ntlafatsa ts'ebetso ea tsona le ho li etsa hore li lumellane le lits'ebetso tse ikhethileng, li-additives tse fapaneng li kenyelletsoa mefuteng ea sekhomaretsi e thehiloeng ho latex. Har'a li-additives tsena, li-cellulose ethers li bapala karolo ea bohlokoa, ho fana ka lintho tse lakatsehang tse kang ho laola viscosity, ho boloka metsi, le ntlafatso ea ho khomarela.

Thepa ea Cellulose Ethers:

Li-cellulose ethers li tsoa ho cellulose, polima ea tlhaho e fumanehang maboteng a lisele tsa semela. Li fumanoa ka ho fetola selulose ka lik'hemik'hale ka karabelo ea etherification. Mefuta e atileng haholo ea li-cellulose ethers tse sebelisoang ho li-adhesives tse thehiloeng ho latex li kenyelletsa methyl cellulose (MC), hydroxyethyl cellulose (HEC), hydroxypropyl cellulose (HPC), le carboxymethyl cellulose (CMC). Mofuta o mong le o mong o bonts'a thepa e ikhethang e tlatsetsang ts'ebetsong ea li-adhesives tse thehiloeng ho latex.

Taolo ea Viscosity:

E 'ngoe ea mesebetsi e ka sehloohong ea li-cellulose ethers ho li-adhesives tse thehiloeng ho latex ke taolo ea viscosity. Ho eketsoa ha cellulose ethers ho thusa ho lokisa viscosity ea sebopeho sa sekhomaretsi, ho etsa hore ho be bonolo ho sebetsana le ho sebetsa. Ka ho fetola viscosity, li-cellulose ethers li thusa ho laola phallo le ho hasana ha sekhomaretsi, ho netefatsa tšireletso e tšoanang le matla a tlamahano.

Paballo ea Metsi:

Li-cellulose ethers ke li-polymers tsa hydrophilic tse khonang ho monya le ho boloka limolek'hule tsa metsi. Lits'ebetsong tsa sekhomaretsi tse thehiloeng ho latex, thepa ena e molemo ka ho khetheha kaha e ntlafatsa nako e bulehileng ea sekhomaretsi — nako eo sekhomaretsi se lulang se sebetsa ka mor'a kopo. Ka ho liehisa ts'ebetso ea ho omisa, li-cellulose ethers li atolosa fensetere bakeng sa boemo bo nepahetseng le ho lokisoa ha li-substrates tse tlanngoeng, kahoo li nolofatsa li-bond tse matla le tse ka tšeptjoang haholoanyane.

Ntlafatso ea ho khomarela:

Li-cellulose ethers le tsona li kenya letsoho ts'ebetsong ea sekhomaretsi sa sekhomaretsi ka ho khothaletsa litšebelisano tsa sefahleho lipakeng tsa sekhomaretsi le bokaholimo ba karoloana. Ka ho kopanya haedrojene le mekhoa e meng, li-cellulose ethers li ntlafatsa ho kolobisa le ho khomarela likaroloana tse fapaneng, ho kenyelletsa lehong, pampiri, masela le lirafshoa. Sena se fella ka matla a ntlafetseng a tlamo, ho tšoarella, le ho hanyetsa maemo a tikoloho a kang ho fetoha ha mongobo le mocheso.

Ho lumellana le Latex Polymers:

Molemo o mong oa bohlokoa oa li-cellulose ethers ke ho lumellana ha tsona le li-polymers tsa latex. Ka lebaka la tlhaho ea bona e tšoanang ea hydrophilic, cellulose ethers e hasana ka mokhoa o ts'oanang ka har'a latex dispersions ntle le ho ama botsitso ba bona kapa thepa ea rheological. Tšebelisano ena e tiisa kabo e ts'oanang ea li-additives ho pholletsa le matrix ea sekhomaretsi, ka tsela eo e ntlafatsa ts'ebetso le ho fokotsa ho se lumellane ha moralo.

Tikoloho e tsitsitseng:

Li-cellulose ethers li tsoa mehloling e tsosolositsoeng, e leng se etsang hore e be li-additives tse tsitsitseng tsa tikoloho bakeng sa li-adhesives tse thehiloeng ho latex. Ho fapana le li-polymers tsa maiketsetso, tse nkiloeng ho lik'hemik'hale tsa petrole, li-cellulose ethers li khona ho senyeha 'me li na le tšusumetso e fokolang ea tikoloho. Ha tlhoko ea litharollo tsa sekhomaretsi tsa eco-friendly e ntse e hola, li-cellulose ethers li fana ka mokhoa o mong o tlamang bakeng sa bahlahisi ba batlang ho fokotsa sebaka sa bona sa khabone le ho latela melao ea ts'ebetso.

Qetello:

cellulose ethers e bapala karolo ea bohlokoa ho ntlafatseng ts'ebetso ea likhomaretsi tse thehiloeng ho latex lits'ebetsong tse fapaneng. Ho tloha taolong ea viscosity le ho boloka metsi ho ntlafatsa ho khomarela le ho boloka tikoloho, li-cellulose ethers li fana ka melemo e mengata e tlatsetsang ho theheng le ho sebetsa ha li-adhesive tsena. Ha liindasteri li ntse li tsoela pele ho ntlafatsa le ho batla mekhoa e meng e tala, li-cellulose ethers li ikemiselitse ho lula e le li-additives tsa bohlokoa ho nts'etsopele ea litharollo tsa sekhomaretsi sa moloko o latelang.
