Usetyenziso oluqhelekileyo lweePolymer Powders eziDispersible

I-powder yerabha yenziwa ngubushushu obuphezulu, uxinzelelo oluphezulu, ukomisa ukutshiza kunye ne-homopolymerization kunye neentlobo ezahlukeneyo ze-micropowder zokuqinisa ezisebenzayo, ezinokuphucula kakhulu amandla okudibanisa kunye namandla okuqina odaka, kwaye inomsebenzi olungileyo wokwakha wokuchasana nokuwa, ukugcinwa kwamanzi. kunye nokutyeba, ukumelana namanzi kunye nokumelana nokunyibilika komkhenkce, ukumelana nokuguga okugqwesileyo, izithako ezilula, kulula ukuzisebenzisa, okusivumela ukuba sivelise udaka oluxubeneyo olukumgangatho ophezulu. Ukusetyenziswa okuqhelekileyo kweepolymer powders ezinokuphinda zihlakazwe zezi:

I-Adhesives: i-adhesives tile, i-adhesives yokwakha kunye neepaneli ze-insulation;

Udaka oludongeni: udaka lwangaphandle olufakwe eludongeni, udaka lokuhombisa;

Udaka lomgangatho: udaka oluzilinganisayo, udaka lokulungisa, udaka olungangeni manzi, i-agent eyomileyo yojongano lomgubo;

Ukugquma umgubo: udonga lwangaphakathi nangaphandle kunye nomgubo wesilingi, umgubo welatex oguquliweyo udaka lwesamente kunye nepeyinti;

Isigcwalisi esidibeneyo: i-tile grout, udaka oludibeneyo.

I-latex powder edispersible ayifuni ukugcinwa kunye nokuthuthwa kunye namanzi, okunciphisa iindleko zokuthutha; inexesha elide lokugcina, i-antifreeze, kwaye kulula ukuyigcina; ukupakishwa kuncinci ngobungakanani, ukukhanya ngobunzima, kwaye kulula ukuyisebenzisa; inokuxutywa kunye ne-hydraulic binders, eyenziwe I-synthetic resin modified premix ingasetyenziselwa kuphela ngokudibanisa amanzi, angagcini nje ukuphepha iimpazamo ekuxubeni kwindawo yokwakha, kodwa iphucula ukhuseleko lokuphathwa kwemveliso.

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. iye yaphucuka.

I-latex powder ehlaziywayo ihlakazwa ukuze yenze ifilimu kwaye isebenze njengento yokuqinisa njenge-adhesive yesibini; i-colloid ekhuselayo ixutywe yinkqubo yodaka (ayiyi kutshatyalaliswa ngamanzi emva kokubunjwa kwefilimu, okanye "i-dispersion yesibili"); ifilimu yokwenza i-polymer resin Njengezinto eziqiniswayo, ihanjiswa kuyo yonke inkqubo yodaka, ngaloo ndlela ikhulisa ukudibanisa komdaka.
