I-ePS Granular Thermal Insulational Infartar Insuration Ukufakwa okulula okushisayo okuhlanganiswe ne-Inorganic Binder, I-Organic Binder, Ukuhlanganiswa, Ukuhlanganiswa kanye nokukhanya Kokukhanya Kokunye Kwengxenye ethile. Ocwaningweni lwamanje nokusetshenziswa kwe-EPS izinhlayiyana inxantathu, i-recypluble redisperserible I-Latex Latex Towx inethonya elikhulu ekusebenzeni kodaka futhi lihlale ligxile kakhulu ezindlekweni, ngakho-ke bekulokhu kugxilwe ukunakwa. Ukusebenza kweBonding kwe-EPS yizinhlayiyana zokufakwa kwe-ePs okushisayo kwangaphandle koLonga lwangaphandle odongeni lokufakwa kodonga olungaphandle ikakhulukazi oluvela ku-polymer binder, futhi ingxenye yayo i-viny acetate / ethylene copolymer / ethylene copolymer. Lolu hlobo lwe-polymer emulsion lungafakelwa isifutho sokuthola i-redisperperiblex powder. Ngenxa yokulungiswa okuqondile kwe-latex ye-latex evuselelayo ekwakheni, ukuhambisa okulula kanye nesitoreji esikahle, i-powder evulekile yama-polymers seyenze umkhuba wokuthuthuka ngenxa yokulungiselela okuqondile, ukuhambisa okulula kanye nesitoreji esilula. Ukusebenza kwe-EPS kuyizinhlayiyana ze-EPS kuncike kakhulu kuhlobo nenani le-polymer elisetshenzisiwe. I-Ethylene-vinyl acetate latex powder (EVA) enokuqukethwe okuphezulu kwe-ethylene kanye ne-tg ephansi (izinga lokushisa le-glass) inani elingcono linezakhiwo ezingcono ngokuya ngamandla othonya, amandla e-bond kanye nokumelana kwamanzi.
Ukusebenziseka kahle kokusebenza kwe-latex powder evuselelayo ngodaka kungenxa yokuthi i-polymer powder iyi-polymer ephezulu yamangqamuzana anamaqembu ama-polar. Lapho i-RDP ihlanganiswa ne-EPS izinhlayiya, ingxenye engeyona i-polar ku-main chain ye-polymer powder izosebenza ngokomoya adsorb nge-exporb engeyona eye-polar ye-EPS. Amaqembu ama-polar e-polymer athambekele ngaphandle ebusweni bezinhlayiya ze-EPS, okwenza izinhlayiya ze-EPS zishintshe kusuka ku-hydrophobic ku-hydrophobic. Ngenxa yokuguqulwa kobubanzi bezinhlayiya ze-EPS nge-polymer powder, inkinga yokuthi izinhlayiya ze-EPS kulula ukuhlangabezana nazo zixazululwa. Ukuntanta, izinkinga ezinkulu zokuphonsa ngodaka. Ngalesi sikhathi, lapho ungeza usimende nokuvusa, amaqembu ama-polar adslorbed ebusweni bezinhlayiya ze-EPS axhumana nezinhlayiya ze-EPS futhi ahlanganise kakhulu, okuthuthukisa kakhulu ukusebenziseka kodumo lwe-EPS insulation. Lokhu kuboniswa eqinisweni lokuthi izinhlayiya ze-EPS zimanzi kalula nge-slurry kasimende, futhi amabutho abugqilayo phakathi kwalokhu okubili athuthukiswa kakhulu.
Ngemuva kwe-emulsion kanye ne-latex evuselelayo ye-latex yakhiwa kwifilimu, ingakha amandla aphezulu ashubile namandla okubopha ngezinto ezahlukahlukene. Zisetshenziswa njenge-binder yesibili ku-datar ukuze ihlanganise nosimende we-inorganic birner, usimende kanye ne-polymer ngokulandelana. Dlala amandla ahambisanayo futhi uthuthukise ukusebenza kodaka. Ngokubheka impahla ye-microsmer-cement composite impahla ye-polymer-cement composite, kubhekwa ukuthi ukwengeza i-latex evuselelayo ye-latex kungenza ingxenye yodonga lwe-polymer, bese wenza ifomu lodaka libe yindawo yangaphakathi, ethuthukisa okwangaphakathi amandla odaka. Amandla e-polymer, ngaleyo ndlela akhuphule ukucindezela ukwehluleka kodaka nokwandisa ubunzima bokugcina. Ukutadisha ukusebenza kwesikhathi eside kwe-latex ye-latex ye-latex evuselelayo, kuphawulwe ngokuskena ama-microscope we-elektroni, ngemuva kweminyaka eyi-10, ukucinanisa i-polymer kungashintshiwe, kugcina amandla aqinile, amandla acindezelayo kanye ne-hydrophobic enhle . Ukuthatha i-latex ye-latex ye-latex njengento yocwaningo, indlela yokwakheka kwamandla okubuyisa ama-tile afundwa, futhi kwatholakala ukuthi ngemuva kokuba i-polymer yomiswe ifilimu, ifilimu le-polymer yakha ukuxhumana okuguqukayo phakathi kodaka kanye nethayili ngakolunye uhlangothi , ngakolunye uhlangothi, ama-polymers asongomeni akhulisa okuqukethwe komoya kodaka, ethinta iflethi kanye nokungabilika kobuso, futhi kamuva ngesikhathi senqubo yokusetha, ama-polymers nawo anomthelela omuhle kwinqubo ye-hydration kanye ne-shrinkage ye usimende. Adhesives, laba bonke basiza ukukhulisa amandla ebhondi.
Ukungeza i-latex ye-latex ye-latex evuselelayo ku-dolor kungathuthukisa kakhulu amandla abugqilayo nezinye izinto, ngoba ukumiswa koketshezi kungena kuma-pores kanye ne-capillaries ye-matrix, ngenkathi i-latex powder ingena kuma-pores naku capillary. Ifilimu langaphakathi yakhiwa futhi ihlanganiswe ngokuqinile ebusweni be-substrate, ngaleyo ndlela iqinisekise amandla amahle okubopha phakathi kwezinto ezibunjiwe kanye ne-substrate.
