I-RDP ye-putty eludongeni

Inokuphinda ihlakazweIpolymer powder RDP/VAE, i-emulsion ekhethekileyo yokutshiza i-powder yokumisa eyenziwe nge-ethylene kunye ne-vinyl acetate copolymer, ngenxa yobuchule bayo obuphezulu bokubambisana kunye neempawu ezizodwa, ezifana: ukuxhathisa kwamanzi, ukwakhiwa kunye nokushisa ukushisa, ngoko, kunoluhlu olubanzi kakhulu lwezicelo.

eyiphi indima yeRDPingadlala ngaphakathiiputty eludongeni?

1, ukuphucula ukunamathela kunye neempawu zoomatshiniiputty eludongeni. Inokuphinda ihlakazweIpolymer powder RDP/VAEekudibaneni namanzi kunokusasazwa ngokukhawuleza kwi-emulsion, kwaye ineempawu ezifanayo njenge-emulsion yokuqala, oko kukuthi, ukukhuphuka kwamanzi kungenza ifilimu, le filimu inokuguquguquka okuphezulu, ukuchasana kwemozulu kunye nokunamathela okuphezulu kwiintlobo ezahlukeneyo ze-substrates.

2, ukuphucula umanyano lweiputty eludongeni, ukuxhathisa okugqwesileyo kwe-alkali, ukuxhathisa ukunxiba, ukwandisa amandla okuguquguquka.

3, ukuphucula ukumelana kwamanzi kunye nokungena kwamanziiputty eludongeni.

4, ukuphucula ukugcinwa kwamanziiputty eludongeni, ukwandisa ixesha lokuvula.

5, ukuphucula ukuxhathisa impembelelo kunye nokwandisa ukuqina kweiputty eludongeni.

In iputty eludongeniunakoI-polymer powder enokuchithwa kwakhonasisongezo esibaluleke kakhulu, ngokuthetha ngokubanzi, i-putty yangaphakathi yodonga inokongezwa okanye hayi. Kodwa eludongeni lwangaphandleiputty eludongenikufuneka yongezwe kukusasazwa kweipolymer powder, inokuba kukusasazwa kweipolymer powderkwiiputty eludongeniinokuqina okuhle kunye namandla kade, ukuthintela ukwenzeka komgubo kade kunye nezinye iingxaki.

Abathengi bahlala bebuza imibuzo malungaiputty eludongeni, njengeiputty eludongenikulula ukukhupha umgubo, umgubo onobungozi, okanye amandla amancinci njalo njalo. Bonke bayaziiputty eludongeniidinga ukongeza i-cellulose ether, abasebenzisi abaninzi abongezi i-dispersibleipolymer powder. Kuba iya kwandisa iindleko zeiputty eludongeni, ngoko ukuze kugcinwe iindleko, abathengi abaninzi abafaki, yingakho i-putty ilula umgubo ingxaki engundoqo yomgangatho!

Iselulosietherinokufunxa ukufuma xa isandiswa ngamanzi. Indima ephambili ye-cellulose kukugcina amanzi, kodwa iya kuhamba kancinciiRDPpowder emva kwexesha elide. Olu hlobo lwe-putty lukhululekile, izinga lokufunxa amanzi liphezulu, umgubo olula, akukho mandla, akukho kunwebeka. Ukuphucula i-putty ngasentla iingxaki kunokulungelelanisa i-putty formula, ukudibanisa okufanelekileyo kwezinye ezihlakaziweyoipolymer powderukuphucula amandla kade kweiputty eludongeni.

I-Putty kwinkqubo yokuvelisa ukuba unokongeza ngokwaneleyoReziyasasazekaintle ipolymer powder, okanye sebenzisa iputty yodidi oluphantsiipolymer powder, yintoni impembeleloiya putty eludongeniunayo ?

iputty eludongeniingaba kwiRedispersible polymer powder RDP/VAEukongeza ngaphantsi, eyona ntsebenzo ichanekileyo yi-putty layer ekhululekile, umgubo ongaphezulu, ukulinganisa okungahambi kakuhle, kunzima ukwenza ifilimu eshinyeneyo. Olu donga luthanda ukuxobuka, ukudumba, ukuxobuka, ukuqhekeka kunye nezinye izinto. Ukuba ngaphantsiiputty eludongeniikhethiwe, udonga luya kuvelisa iigesi eziyingozi, ezifana ne-formaldehyde kunye nezinye umonakalo womzimba womntu zibonakala.

Ngoko ke, isiseko somgangatho ophezuluiputty eludongeniimveliso kukukhetha i-hydroxypropyl methyl cellulose elungileyoHPMCkwaye ziphinde zisasazweipolymer powder RDPkunye nezinye izongezo zemveliso ukuvelisa iimveliso eziluhlaza.
