Mokhoa oa ho ntlafatsa constructability ea selulose leboteng phahameng mocheso lehlabula

Hona joale, e se e tla kena lehlabula, 'me mocheso o batla o phahame, haholo-holo sebakeng se ka leboea.Mocheso o phahame 'me moea o omme.Mocheso oa holim'a lerako o ka fihla ho 60°C.Ka lebaka la mocheso, selulose hangata e na le mathata a kang ho haha ​​​​ntle le ho tlosoa ha phofo nakong ea kaho.Lebaka le ka sehloohong ke hore ka lebaka la mocheso o phahameng oa lerako, ho boloka metsi a putty ha ho molemo, kahoo metsi a putty a kenngoa ka potlako kapa a fetoha mouoane ke lerako, e le hore putty e se ke ea koaheloa khafetsa le ho phunyeletsoa.Ho hlaha sekoti le ho ebola.Mokhoa oa ho ntlafatsa ho bolokoa ha metsi ka putty ea bokantle ba lebota haholo-holo o na le mekhoa e latelang:

1. Eketsa palo ea cellulose ether

Cellulose ether e na le ho boloka metsi hantle, empa ts'ebetso ea ho boloka metsi ha e eketsehe ka mor'a hore palo e itseng ea cellulose ether e eketsoe.Ka nako e ts'oanang, ho eketseha ha selulose ho eketsa viscosity ea putty mme kaho ha e boreleli.Ho phaella moo, litšenyehelo tsa putty lia eketseha.

2. Eketsa palo ea lignocellulose

Lignocellulose e na le phello e itseng ea ho boloka metsi.Ho eketsoa ha fiber ea lehong ho ntlafatsa matla a ho boloka metsi a thepa, ho etsa hore tsamaiso ea lisebelisoa e be le metsi ka mokhoa o ts'oanang, 'me e ka ntlafatsa ho sebetsa ka nako e le' ngoe, empa molao-motheo oa ho boloka metsi oa lignocellulose o fapane le oa selulose.E na le tšobotsi ea ho monya moriri.(Ho tsamaisa metsi), ho tla ba le mongobo pakeng tsa fiber e 'ngoe le e' ngoe, 'me ha mongobo o tikolohong e potolohileng fiber o fetoha' me o fokotseha, mongobo o pakeng tsa likhoele o tla lokolloa ka mokhoa o lekanang.Nako ea ho bula, ha ho bonolo ho petsoha.Leha ho le joalo, hobane botenya ba putty leboteng la kantle bo tšesaane haholo, botenya ba seaparo se seng le se seng sa scrape ke 0.5-1mm feela.Ha mocheso oa holim'a lera la motheo le mocheso oa moea o batla o phahame, ts'ebetso ea oona ea ho boloka metsi ha e totobetse, 'me ts'ebetso ea ho roala ka makhetlo a mangata ke karolelano.

3. Eketsa palo ea polymer

Maboteng a nang le putty e tšesaane, moea o omileng le mocheso o phahameng oa motheo, ho eketsa palo ea polymer ke e 'ngoe ea litsela tse molemohali tsa ho etsa hore putty e be le thepa ea ho senya khafetsa, empa theko ea redispersible latex powder e batla e phahame, palo e kholo e tla eketseha haholo. theko ea putty.E ka boela ea phetha karolo e molemo ka ho eketsa phofo e nyenyane ea joala ea polyvinyl, empa viscosity ea phofo ea joala ea polyvinyl e batla e le khōlō, e tla ama ts'ebetso ea ho sebetsa, 'me thepa ea sanding ea putty ha e ntle..

4. Kenya lubricant ea polymer

Ka tlhahlobo, ho nkoa e le khetho e ntle ea ho eketsa lubricant e phahameng ka ntle ho lebota la putty tikolohong ea mocheso o phahameng lehlabula.Lubricant ke ea motsoako oa polymer, 'me setlolo sa rheological se reretsoe haholo ho ntlafatsa ts'ebetso ea kaho tsamaisong ea samente.Nako e bulehileng le ts'ebetso e tsitsitseng.E eketsa bokhoni ba ho sebetsa le ho hanyetsa ho senyeha ha lirafshoa, li-plaster, li-renders, li-plaster le li-adhesives le ho thibela ho senyeha ha samente ea ho itšeha.Lebaka la ho boloka metsi ke hore ho na le palo e kholo ea lihlopha tse sebetsang tsa hydrophilic ka ketane ea eona ea limolek'hule.Tabeng ea ho senya le ho roala khafetsa, e ke ke ea lahleheloa ke metsi, e na le ts'ebetso e tsotehang ea ho boloka metsi, 'me e na le thickening le thixotropy ka nako e le' ngoe, e etsa hore mohaho o be bonolo 'me o ka nkela cellulose sebaka, empa theko ea eona ke cellulose ether feela, tekanyo ea eona ke 0.1-0.2%., ke thepa e theko e boima haholo, haeba e sebelisoa hammoho le cellulose ether, lignocellulose, le redispersible latex powder, phello e tla ba molemo.
