Umgubo wepolymer odispersible yipolymer eyomisiweyo ngumgubo osekelwe kwi-polymer emulsioni-ethylene-vinyl acetate copolymer.Yinto ebalulekileyo kwi-drymix mortar yanamhlanje.Zeziphi iziphumo ezenza ii-polymer powder enokuchithwa kwakhonaube nodaka lwesakhiwo?
I-polymer powder particles ehlaziywayo igcwalisa i-cavity ye-mortar, ubuninzi bomdaka buyanda, kwaye ukuchasana kokugqoka kuphuculwe.Ngaphantsi kwesenzo samandla angaphandle, kuya kuvelisa ukuphumla ngaphandle kokutshatyalaliswa.Ifilimu yepolymer inokugcinwa ngokusisigxina kwinkqubo yodaka.
1. Ukuphucula ukusebenza kolwakhiwo lodaka
Emva kokuba i-latex powder enokuchithwa kwakhona njenge-binder ye-organic yenziwe ifilimu, inokwenza amandla aphezulu kunye namandla adibeneyo kwii-substrates ezahlukeneyo.Idlala indima ebalulekileyo ekunamatheleni komdaka kwizinto eziphilayo (i-EPS, ibhodi ye-foam ekhutshweyo) kunye ne-substrates egudileyo.Ifilimu yokwenza i-polymer powder ihanjiswa kulo lonke inkqubo yodaka njengento yokuqinisa ukunyusa ukudibanisa komdaka.
2. Ukuphucula ukuxhathisa kwemozulu, ukumelana nomkhenkce kunye nokumelana nokuqhekeka kodaka
I-polymer e-redispersible powder yi-resin ye-thermoplastic ene-flexibility efanelekileyo, enokwenza udaka lukwazi ukujamelana nokutshintsha kwendawo ebandayo yangaphandle kunye neshushu, kwaye ikhusele ngokufanelekileyo udaka ekuqhekekeni ngenxa yokutshintsha kweqondo lokushisa.
3. Ukuphucula i-hydrophobicity yodaka kunye nokunciphisa ukufunxa kwamanzi
I-polymer powder ehlaziywayo yenza ifilimu kwi-cavity kunye nomgangatho womdaka, kwaye ifilimu ye-polymer ayiyi kuphinda ihlakazeke emva kokuba ibonakaliswe emanzini, okuthintela ukungena kwamanzi kunye nokuphucula ukungabonakali.Ekhethekileyoi-latex powder enokuchithwa kwakhonangesiphumo se-hydrophobic inesiphumo esingcono se-hydrophobic.
4. Ukuphucula amandla okugoba kunye namandla aguquguqukayo odaka
Ifilimu ye-polymer eyenziwe yi-polymer powder ephindwe kabini inokuguquguquka okulungileyo.Iifilimu zenziwe kwizikhewu kunye nomgangatho wamasuntswana odaka lwesamente ukwenza unxibelelwano oluguquguqukayo.Ngaloo ndlela, i-brittle kunye ne-hard mortar ye-samente iba yi-elastic.Udaka olunomlinganiselo owongeziweyo womgubo wepolymer ophinda-phindwe kabini uphezulu ngokuphindwe kaninzi kunodaka oluqhelekileyo ngokwemiqathango yokuqina kunye nokugoba.
I-Longou compat, njengenkokeliUmzi-mveliso weRDPe China, isoloko igxile ekuboneleleni protucts ezikumgangatho ophezulu kunye nesisombululo technocali-drymix udaka.Wamkelekile ukuba uqhagamshelane nathi ngeenkcukacha ezininzi eziphathekayo.
