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, kusetshenziswa njenge-pinder yesibili ekuhlanganiseni usimende wokuhlanganisa ukuhlanganisa amandla ahambisanayo ukuze uthuthukise ukusebenza kodaka. Ngokubheka impahla ye-miscmer-cement composite impahla eyinhlanganisela, kukholelwa ukuthi ukungezwa kwe-polyx evuselelayo kungenza i-polymer yakha ifilimu futhi yenze ingxenye yodonga lwangaphakathi, oluthuthukisa amandla angaphakathi odaka. 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-tader evuselelayo ye-latex, futhi yatholakala ukuthi ngemuva kokuthi i-polymer yomiswe ngefilimu, futhi ngakolunye uhlangothi, i-polymer ku-polymer ngakolunye uhlangothi, futhi ngokuhamba kwesikhathi kwesettability, bese kamuva ngesikhathi senqubo yokusetha I-polymer nayo inethonya elihle kwinqubo ye-hydration kanye ne-shrinkage ye-shrinsage ye-clemende ku-binder, konke lokhu kuzosiza ukuthuthukisa amandla e-bond.
Ukungeza i-latex ye-latex evuselelayo ku-turnar kungathuthukisa kakhulu amandla okubopha nezinye izinto, ngoba i-hydrophilic latex puleza ingena kuma-pores kanye ne-capillaries ye-matrix, futhi i-latex powder ingena kuma-pores nama-capillaries. Ifilimu langaphakathi yakhiwa futhi ihlanganiswe ngokuqinile ebusweni be-substrate, ngaleyo ndlela iqinisekise amandla amakhulu obuhlobo phakathi kwezinto eziqinisekisiwe kanye ne-substrate.
