I-latex powder e-redispersible ine-redispersibility enhle, iphinde ihlakazeke ibe yi-emulsion lapho ithintana namanzi, futhi izakhiwo zayo zamakhemikhali zicishe zifane ne-emulsion yokuqala.Ukwengeza i-emulsion ehlakazekayo ye-latex powder kusimende noma i-gypsum-based dry powder exutshwe nodaka olulungile lungathuthukisa izici ezihlukahlukene zodaka, njengokuthi: ukuthuthukisa ukubumbana nokubumbana kwezinto;ukunciphisa ukumuncwa kwamanzi kanye ne-elastic modulus yezinto;ukuqinisa amandla e-Flexural, ukumelana nomthelela, ukumelana nokugqoka kanye nokuqina;ngcono ukusebenza kokwakhiwa kwezinto, njll.
Ukwengeza i-latex powder odakeni lukasimende kuzokwakha ifilimu yenethiwekhi ye-polymer eguquguqukayo kakhulu futhi enwebekayo, ezokwenza ngcono kakhulu ukusebenza kodaka, ikakhulukazi amandla okuqina odaka azothuthukiswa kakhulu.Uma kusetshenziswa amandla angaphandle, ngenxa yokuthuthukiswa kokuhlangana okuphelele kodaka kanye nokunwebeka okuthambile kwe-polymer, ukuvela kwama-micro-cracks kuzosuswa noma kuncishiswe.Ngethonya lokuqukethwe kwe-latex powder emandleni e-thermal insulation mortar, kutholakala ukuthi amandla esibopho esiqinile se-thermal insulation mortar anda ngokwanda kokuqukethwe kwe-latex powder;amandla okuguquguquka namandla okucindezela anezinga elithile ngokunyuka kokuqukethwe kwe-latex powder.Izinga lokwehla, kodwa lihlangabezana nezimfuneko zokuqedwa kodonga lwangaphandle.
Udaka lukasimende oluxutshwe nempushana ye-latex, amandla ayo okubopha angu-28d ayanda ngokwanda kokuqukethwe kwe-latex powder.Ngokukhula kokuqukethwe kwempushana ye-latex, ikhono lokubopha likasimende nodaka lukasimende oludala luyathuthukiswa, okuqinisekisa izinzuzo zalo eziyingqayizivele zokulungisa umgwaqo ogandayiwe usimende nezinye izakhiwo.Ngaphezu kwalokho, isilinganiso sokugoqa sodaka siyakhula ngokwanda kokuqukethwe kwe-latex powder, futhi ukuguquguquka kodaka olungaphezulu kuyathuthuka.Ngesikhathi esifanayo, ngokwanda kokuqukethwe kwe-latex powder, i-modulus elastic of mortar iyancipha kuqala bese iyanda.Sekukonke, ngokwanda kwesilinganiso sokuqoqwa komlotha, i-elastic modulus kanye ne-deformation modulus yodaka iphansi kunaleyo yodaka olujwayelekile.
Ucwaningo lwathola ukuthi ngokwanda kokuqukethwe kwe-latex powder, ukubumbana nokugcinwa kwamanzi odaka kwathuthukiswa kakhulu, futhi ukusebenza komsebenzi kwathuthukiswa.Lapho inani le-latex powder lifinyelela ku-2.5%, ukusebenza kodaka kungahlangabezana ngokugcwele nezidingo zokwakha.Inani le-latex powder akudingeki libe phezulu kakhulu, elingenzi nje kuphela ukuthi i-EPS insulation mortar ibe ne-viscous futhi ine-fluidity ephansi, engahambisani nokwakhiwa, kodwa futhi yandisa izindleko zodaka.
