Phello ea ho eketsa phofo ea Redispersible polymer ho putty powder

Redispersible latex powder e sebelisoa ka karolo e le 'ngoe ea JS e sa keneleng metsi, seretse sa polystyrene bonding bakeng sa ho kenya mohaho, seretse se sireletsang holim'a metsi, polystyrene particle thermal insulation coating, sekhomaretsi sa lithaele, seretse se ikemetseng, seretse se omileng, putty, joalo-joalo. tšimo ea ho fetola thepa ea gelling ea inorganic e sebelisitsoe haholo.

 

Ho eketsa phofo ea latex e ka sebelisoang hape ho putty powder ho ka eketsa matla a eona, ho ba le sekhomaretsi se matla le thepa ea mochini, le ho thusa ho ntlafatsa ho thatafala. E na le khanyetso e ntle ea metsi, ho kenella ka hare ho metsi, le ho tšoarella ho babatsehang. Alkaline, e thibelang ho apara, 'me e ka ntlafatsa ho boloka metsi, ho eketsa nako ea ho bula, le ho matlafatsa nako e telele.

 

Ha phofo ea latex e qhalakantsoeng e ts'oaroa ka mokhoa o ts'oanang ka phofo ea putty 'me e kopantsoe le metsi, e qhalakanngoa ka likaroloana tse ntle tsa polymer; gel ea samente e thehoa butle-butle ka hydration ea pele ea samente, 'me karolo ea mokelikeli e thehoa ke Ca (OH) 2 ts'ebetsong ea hydration. E tletse, ha phofo ea latex e etsa likaroloana tsa polymer le li-deposit holim'a motsoako oa samente oa gel / unhydrated samente motsoako; ha samente e ntse e na le metsi a mangata, metsi a li-capillaries a fokotseha, 'me likaroloana tsa polymer li thibeloa butle-butle li-capillaries. Motsoako oa sekhomaretsi / unhydrated samente particle le bokaholimo ba ho tlatsa bo etsa lera le haufi-ufi; tlas'a ketso ea hydration karabelo, botlaaseng lera absorption le holim'a e le mouoane holim'a metsi, metsi a fokotseha ka ho eketsehileng, 'me ho thehoa stacked lera bokella ka filimi, e tlamang hydration karabelo sehlahiswa ka Together ba theha e feletseng netweke sebopeho. Sistimi e kopaneng e entsoeng ke samente hydration le sebopeho sa filimi ea phofo ea latex e ka ntlafatsa ho hanyetsa ho matla ha putty ka ketso e kopaneng.

 

Li-putty tse sebelisoang e le lesela la phetoho pakeng tsa lerako la ka ntle le pente ha lia lokela ho ba matla ho feta seretse sa plastering, ho seng joalo ho phunyeha ho tla etsahala habonolo. Tsamaisong eohle ea ho kenya letsoho, ho feto-fetoha ha putty ho lokela ho ba holimo ho feta thepa ea motheo. Ka tsela ena, putty e ka ikamahanya hantle le deformation ea substrate mme ea thibela deformation ea eona tlasa ts'ebetso ea maemo a kantle a tikoloho, ea imolla khatello ea maikutlo, le ho fokotsa monyetla oa ho peperana le ho phunya.
