Tus cwj pwm tseem ceeb rau kev sib thaj yees ntev

Pej xeem xav tias yuav tswj xyuas kev sib thaj yees ntev los ntawm kev muab khoom tsim nyog, kev pab tswj xyuas zoo ib yam, thiab kev pab tshuaj lwm tseem ceeb uas pib ntxig nrog kev lag luam ntawm pej xeem.

Cov khoom sib xws

Polyvinyl alcohol (PVA) yog ib qhov polymer tseem ceeb hauv cheeb tsheb ntawm kev tsim kho los ntawm nws kev zoo siab ntawm dej thiab kev sib ntxiv zoo. PVA tau siv ntau yam li ib qhov ntxiv kom meej nyuaj hauv kev ua neeg ua noj qab nthuav hlau thiab kev lag luam ua neeg tswv yim, thiab li ib qhov ntxiv rau kev tsim kho ntawv thiab hauv paj. Nws txoj kev tsis phem thiab kev raug nqus rau hauv daim ntawv ua rau nws yog qhov leej hnub xaiv rau cov chaw ua haujlwm uas muaj kev xav txog ntawm qhov chaw nyob. Txwv tsis pub, PVA tau siv ntau hauv cheeb tsheb ua hauv paj yam li ib qhov cuab yeej rau kev ntxiv zog rau hauv paj, tshwj tsis thaum kev ua siab. Hauv kev tsim kho, nws tau muab tso rau hauv cement thiab mortar mixes los ntawm nws kev pab ntxiv kev sib ntxig thiab pab kom zoo dua.

Cov Lus Nug Nrov

Redispersible polymer powder siv rau dab tsi hauv kev tshen?

Cov duab ntawm polymer pheej xwm tau zoo dua, zoo li muaj kev txuas ntxiv siab, kev ua haujlwm zoo dua, thiab kev tso siab rau dej hauv cov khoom siv tsim kho. Cov khoom no feem ntau siv rau kev ntxig kab, siv rau kab ntxig dej, siv rau kab ntxig hauv tsev, thiab rau kev ruaj khov hauv tsev kom zoo dua.
Cov duab ntawm duab ntawm polymer uas tuaj yeem rov qab siv tau muab kev yooj yim dua rau kev sau, kev nres, thiab kev nres tshaj tawv dua li cov emulsion hlwb. Thaum muab ntxiv nrog dej, nws rov qab siv los ua emulsion, rov qab muab kev sib sau thiab kev yooj yim rau hauv cov khoom siv hluv lossis cov khoom siv gypsum.
APS ua li thiab los pab sim kho nyob rau hauv qhov chaw sib ntxig. Nws feem ntau siv rau hauv kev tsim kho acrylic, vinyl, thiab kho tshwj xeeb uas xav tau kev sib cuag zoo thiab muaj ceev tshwj xeeb.
Ammonium persulfate raug siv ntau los pab qhia kev tsim polymer emulsion thiab solution rau acrylic polymers thiab latexes. Nws muaj qhov tseem ceeb hauv kev siv hauv dej, kev tseem ceeb, thiab kev lag lag nyob hauv kev lag lag tshuaj lom neeg.
