HPMC e ntlafatsa ts'ebetso ea plaster ea gypsum

Hydroxypropyl methylcellulose (HPMC) ke tlatsetso e feto-fetohang e sebelisoang haholo indastering ea kaho, haholo meahong ea samente.Gypsum plaster, eo hape e tsejoang e le plaster ea Paris, ke thepa ea kaho e tsebahalang e sebelisetsoang ho koahela mabota le siling.HPMC e bapala karolo ea bohlokoa ho ntlafatsa ts'ebetso le ts'ebetso ea plaster ea gypsum.

HPMC ke non-ionic cellulose ether e fumanoang ho tloha selulose ea tlhaho ea polymer ka letoto la liphetoho tsa lik'hemik'hale.E hlahisoa ka ho phekola cellulose ka propylene oxide le methyl chloride.Sehlahisoa se hlahisoang ke phofo e tšoeu e qhibilihang ka metsing 'me e etsa tharollo e hlakileng ea viscous.

Mona ke tse ling tsa lintlha tsa bohlokoa tsa HPMC bakeng sa samente:

1. Ho boloka metsi:

E 'ngoe ea mesebetsi ea mantlha ea HPMC ho gypsum ke bokhoni ba eona ba ho boloka metsi.E thusa ho thibela tahlehelo e potlakileng ea mongobo nakong ea ho omisa, ho lumella hore ho be le taolo e eketsehileng esita le ho beha samente.Sena se bohlokoa ho fihlela matla a hlokahalang le ho tsitsa ha plaster.

2. Ntlafatsa tšebetso:

HPMC e matlafatsa ts'ebetso ea plaster ea gypsum ka ho fana ka nako e ntle ea ho bula le ho eketseha ha khanyetso ea ho thella.Sena se etsa hore ho be bonolo ho sebelisa le ho hasa stucco holim'a metsi, e leng se etsang hore ho be le qetello e boreleli, le ho feta.

3. Ho khomarela le momahano:

HPMC e thusa ho khomarela plaster ea gypsum ho li-substrates tse fapaneng.E ntlafatsa ho khomarela pakeng tsa stucco le bokaholimo bo ka tlaase, ho etsa bonnete ba hore qetello ea nako e telele le e tšoarellang.Ho phaella moo, HPMC e ntlafatsa momahano oa samente ka boeona, kahoo e eketsa matla le ho fokotsa ho phunyeha.

4. Phello e teteaneng:

Ka gypsum formulations, HPMC e sebetsa e le motenya, e amang viscosity ea motsoako oa gypsum.Phello ena e teteaneng e bohlokoa bakeng sa ho fihlela botsitso le sebopeho se lakatsehang nakong ea ts'ebeliso.E boetse e thusa ho thibela stucco hore e se ke ea sisinyeha kapa ea oela holim'a libaka tse otlolohileng.

5. Beha taolo ea nako:

Ho laola nako ea ho beha plaster ea gypsum ho bohlokoa lits'ebetsong tsa meralo.HPMC e ka fetola nako ea tlhophiso ho fana ka monyetla oa ho fihlela litlhoko tse itseng tsa projeke.Sena se bohlokoa haholo bakeng sa merero e meholo e ka hlokang linako tse fapaneng tsa ho seta.

6. Phello ho porosity:

Ho ba teng ha HPMC ho ama porosity ea gypsum.Samente e entsoeng hantle e nang le HPMC e ka eketsa ho hanyetsa ho kenella ha metsi le ho fokotsa porosity, kahoo e eketsa nako e telele le ho hanyetsa maemo a tikoloho.

7. Ho lumellana le li-additives tse ling:

HPMC e lumellana le mefuta e meng ea li-additives tse atisang ho sebelisoa ha ho etsoa gypsum formulations.Ho feto-fetoha hona ho lumella metsoako ea plaster hore e hlophisehe ho fihlela litekanyetso tse ikhethileng tsa ts'ebetso le litlhoko tsa ts'ebeliso.

8. Maikutlo a tikoloho:

HPMC ka kakaretso e nkoa e bolokehile ebile e na le botsoalle ho tikoloho.Ha e na chefo ebile ha e lokolle lintho tse kotsi nakong kapa ka mor'a ho lipola.Sena se tsamaellana le khatello e ntseng e hola ea mekhoa ea kaho e tšoarellang le e baballang tikoloho.

Hydroxypropyl methylcellulose (HPMC) e bapala karolo ea bohlokoa ho ntlafatseng ts'ebetso ea gypsum lits'ebetsong tsa kaho.Ho boloka metsi a eona, ho ntlafatsa ts'ebetso ea ts'ebetso, ho khomarela, ho tiisa phello, ho laola nako, phello ea porosity, ho lumellana le li-additives tse ling le ho nahanisisa ka tikoloho ho etsa hore e be tlatsetso ea bohlokoa mefuteng ea boleng bo phahameng ba gypsum.Ha mekhoa ea kaho e ntse e tsoela pele ho fetoha, HPMC e ntse e le motsoako o ka sehloohong oa ho ntlafatsa ts'ebetso le ho tšoarella ha gypsum plaster mererong e fapaneng ea meaho le ea kaho.
