I-EPS Granural Insulational Infartar Insuration Ukufakwa kwe-Thermalweight Phakathi kwama-ePS Granular Insulal Insurture Insurations Ukusebenza kwe-Bonding kwe-EPS yizinhlayiyana zokufakwa kodumo kwangaphandle kodonga lwangaphandle kodonga oludonswayo ikakhulukazi kusuka ku-polymer bherinder, futhi ukwakheka kwalo ikakhulukazi i-vinyl acetate / ethylene copolymer / ethylete copolymer / ethylene copolymer. I-satex evuselelayo ye-latex ingatholakala ngokufafaza yomiswa lolu hlobo lwe-polymer emulsion. Ngenxa yokulungiselela okuqondile, ukuthutha okulula kanye nokugcinwa okulula kwe-latex ye-latex ye-latex ekwakhiweni, i-powder ekhethekile ye-latex ye-latex isephenduke umkhuba wokuthuthuka ngenxa yokulungiswa kwayo okuqondile, ukuthuthwa okulula kanye nesitoreji esilula. Ukusebenza kwe-EPS kuyizinhlayiyana ze-EPS kuncike kakhulu kuhlobo nenani le-polymer elisetshenzisiwe. I-Ethylene-Vinyl acetate latexr powder
Ukusebenziseka kwe-latex powder ekusebenzeni ngodaka kungenxa yokuthi i-latex powder iyi-polymer ephezulu yama-moleculate enamaqembu ama-polar. Lapho i-latex powder ihlanganiswa ne-EPS izinhlayiya, ingxenye engeyona i-polar ku-main chain ye-latex powmer polymer izokwenzeka ngobuso be-eps. Amaqembu ama-polar e-polymer athambekele ngaphandle ebusweni bezinhlayiya ze-EPS, ukuze izinhlayiya ze-EPS ziguqukele kusuka ku-hydrophobicity ku-hydropholity. Ngenxa yokuguqulwa kobubanzi bezinhlayiya ze-EPS nge-latex powder, ixazulula inkinga ukuthi izinhlayiya ze-EPS zivezwa kalula emanzini. Intanta, inkinga yokugcwala okukhulu kodaka. Ngalesi sikhathi, lapho kufakwa usimende futhi kuxutshwe, amaqembu ama-polar adderbed ebusweni bezinhlayiya ze-EPS axhumana nezinhlayiya ze-EPS futhi ahlanganise eduze, ukuze ukusebenziseka kodumo kudunyiswa kwe-EPS kwenziwa ngcono. Lokhu kuboniswa eqinisweni lokuthi izinhlayiya ze-EPS zimanzi kalula ngokonasi kasimende, futhi amabutho aphakathi kwalezi ezimbili athuthukiswa kakhulu.
I-Emulsion kanye ne-latex evuselelayo ye-latex ingakha amandla aphezulu ashubile namandla okubopha ngezinto ezihlukile ngemuva kokwakheka kwefilimu, asetshenziswa njenge-tinder yesibili ngodaka ukuze ahlanganiswe nosimende wokuhlanganisa i-inorganic, asetshenziswe usimende ngokulandelana anikeza ukudlala okugcwele kumandla ahambisanayo ukuthuthukisa i ukusebenza kodaka. Ngokubona impahla ye-microsmmer-cement composite impahla, kukholelwa ukuthi ukwengeza i-latex evuselelayo ye-latex kungenza i-polymer yakha ifilimu futhi ibe yingxenye yodonga lomgodi, okuthuthukisa amandla angaphakathi lodaka. Amandla we-polymer, ngaleyo ndlela athuthukise ukucindezela ukwehluleka kodaka nokwandisa ubunzima bokugcina. Ukuze utadishe ukusebenza kwesikhathi eside kwe-latex ye-latex tattex e-wortar, kwaqashelwa yi-sem yalokho ngemuva kweminyaka eyi-10, i-microssmer ye-polymer kudaka ayikashintshi, igcina amandla aqinile, ukupenda kwamanzi okuhle. Indlela yokwakheka kwamandla okunamathela kwamathayili yafundwa e-tablex evuselelayo ye-latex, futhi yatholakala ukuthi ngemuva kokuthi i-polymer yomiswe kwifilimu, ifilimu le-polymer yakha ukuxhumana okuguqukayo phakathi kodaka kanye nethayili ngakolunye uhlangothi, futhi the other hand, The polymer in the mortar increases the air content of the mortar and affects the formation and wettability of the surface, and subsequently during the setting process the polymer also has a favorable influence on the hydration process and shrinkage of the cement in the I-Binder, konke lokhu kuzosiza ukuthuthukisa amandla webhondi.
Ukungeza i-latex ye-latex evuselelayo ku-dolor kungathuthukisa kakhulu amandla okubopha nezinye izinto, ngoba i-hydrophilic latex puleza ingena kuma-matrix kanye ne-capillaries ye-matrix, futhi i-latex powder ingena kuma-pores kanye nama-capillaries . Ifilimu langaphakathi yakhiwa futhi ihlanganiswe ngokuqinile ebusweni be-substrate, ngaleyo ndlela iqinisekise amandla amakhulu obuhlobo phakathi kwezinto eziqinisekisiwe kanye ne-substrate.
