Ukusetyenziswa okuphambili kwe-latex powder edibeneyo
Iputty eludongeni lwangaphakathi nangaphandle, i-adhesive yethayile, i-agent ekhomba i-tile, i-agent eyomileyo yokudibanisa i-ejenti, i-thermal insulation mortar yangaphandle yeendonga zangaphandle, i-self-leveling mortar, udaka lokulungisa, udaka lokuhombisa, udaka olungangeni manzi lwangaphandle lwe-thermal edibeneyo eyomileyo exutywe nodaka. Kumda, kukuphucula i-brittleness, imodyuli ephezulu e-elastiki kunye nobunye ubuthathaka bodaka lwesamente lwemveli, kunye nokunika udaka lwesamente ngokuguquguquka okungcono kunye namandla okuqina kwebhondi, ukwenzela ukuxhathisa kunye nokulibazisa ukuveliswa kweentanda zodaka lwesamente. Ekubeni i-polymer kunye nodaka lwenza i-interpenetrating network structure, ifilimu ye-polymer eqhubekayo yenziwa kwiipores, eyomeleza ukudibanisa phakathi kwee-aggregates kunye neebhloko ezinye ii-pores kumdaka, ngoko udaka olulungisiweyo emva kokuqina lungcono kunodaka lwesamente. Kukho uphuculo olukhulu.
Iipropathi zemveliso ye-latex powder ephindwe kabini
1. 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. Udaka lwesamente olunzima noluphukayo luba ilastiki. Udaka olongeziweyo ngomgubo we-latex oludispersible luphindaphindeka kaninzi kwi-tensile kunye nokumelana nokuguquguquka kunodaka oluqhelekileyo.
2. Ukuphucula amandla okudibanisa kunye nokudityaniswa kodaka
Emva kokuba i-latex powder ephinda ihlakazwe njenge-organic binder yenziwe ifilimu, inokwenza amandla aphezulu kunye namandla okudibanisa kwii-substrates ezahlukeneyo. Idlala indima ebalulekileyo ekunamatheleni komdaka kwizinto eziphilayo (i-EPS, ibhodi ye-foam ekhutshweyo) kunye ne-substrates egudileyo. Ifilimu ye-polymer ye-polymer powder isasazwa kulo lonke inkqubo yodaka njengento yokuqinisa ukunyusa ukudibanisa komdaka.
3. Ukuphucula ukuchasana kwempembelelo, ukuqina kunye nokuxhatshazwa kokugqoka komdaka
Iinqununu ze-rubber ze-powder zigcwalisa i-cavity ye-mortar, ubuninzi bomdaka buyanda, kwaye ukuxhatshazwa kokugqoka kuphuculwe. Ngaphantsi kwesenzo samandla angaphandle, kuya kuvelisa ukuphumla ngaphandle kokutshatyalaliswa. Ifilimu ye-polymer ingabakho ngokusisigxina kwinkqubo yodaka.
4. Ukuphucula ukuxhathisa kwemozulu kunye nokumelana nokunyibilika kodaka, kwaye uthintele udaka ekuqhekekeni
I-redispersible latex 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.
5. Ukuphucula i-hydrophobicity yodaka kunye nokunciphisa ukufunxa kwamanzi
I-latex powder ehlaziywayo yenza ifilimu kwi-cavity kunye nomgangatho womdaka, kwaye ifilimu ye-polymer ayiyi kuphinda ihlakazeke emva kokuba ibonakaliswe kumanzi, okuthintela ukungena kwamanzi kunye nokuphucula ukungabonakali. I-latex ekhethekileyo ye-latex powder enefuthe le-hydrophobic, i-hydrophobic effect engcono.
6. Ukuphucula ukusebenza kolwakhiwo lodaka
Kukho umphumo wokuthambisa phakathi kweepuphu ze-polymer rubber powder, ukwenzela ukuba amacandelo omdaka akwazi ukuhamba ngokuzimeleyo. Ngelo xesha, i-powder ye-rubber inempembelelo yokuphefumula emoyeni, inika ukunyanzeliswa kodaka kunye nokuphucula ukwakhiwa kodaka.
