I-latex powder ephinda iphinde iphuculwe iphucula ukuguquguquka kunye nokumelana nokuqhekeka kodaka

Emva kokongeza i-latex powder edityanisiweyo kwidaka, umlinganiselo wokunyanzeliswa kunye nomlinganiselo we-tension-compression of the mortar uphuculwe kakhulu, obonisa ukuba i-brittleness ye-mortar iyancipha kakhulu kwaye ukuqina kuphuculwe kakhulu, ukwenzela ukuba ukumelana nokuqhekeka udaka lwaphucuka.

I-latex powder ehlaziywe ngokutsha ilahlekelwa ngamanzi kumdaka ukwenza ifilimu, engagcwalisi kuphela iziphene kunye neepores kwilitye le-samente, kodwa yenza iimveliso ze-samente ze-samente kunye ne-aggregates bond kunye nomnye ukwenza uthungelwano lwe-polymers interpenetrating. I-modulus elastic yodaka iphantsi kunodaka, ngoko ke i-brittleness of mortar iyancitshiswa. Ukuguquguquka kodaka kwandisa umda wokuguqula ubuninzi xa udaka lonakalisiwe, kwaye luyakwazi ukufunxa amandla afunekayo ekwandiseni iziphene kunye ne-micro-cracks ukuya kwinqanaba elikhulu, ukwenzela ukuba udaka lukwazi ukumelana noxinzelelo olukhulu ngaphambi kokungaphumeleli. Ukongezelela, ifilimu ye-polymer inomsebenzi wokuzolula, kwaye ifilimu ye-polymer inomsebenzi we-joint ehambayo kwi-skeleton eqinile eyenziwe kwi-mortar emva kwe-cement hydration, enokuqinisekisa ukuqina kunye nokuqina kwe-skeleton eqinile. Umphezulu wefilimu ye-polymer eyenziwe phezu kweengqungquthela zodaka unama-pores, kwaye umphezulu we-pores uzaliswe ngodaka, ukwenzela ukuba uxinzelelo lwexinzelelo luncitshiswe, kwaye luya kuphumla ngaphandle komonakalo phantsi kwesenzo samandla angaphandle. Ukuphucula ukuguquguquka kunye nokunwebeka kodaka.
