Yintoni iRedispersible Polymer Powder?

I-polymer powder enokuchithwa kwakhona(RPP) i-free-flowing, ipowder emhlophe efunyenwe nge-spray-drying polymer emulsions. Iqukethe iinqununu ze-polymer resin ezihlakazwa emanzini ukuze zenze i-emulsion, eyomiswa ibe yifom powder. I-RPP iqulethe umxube weepolymers, ngokuqhelekileyo i-vinyl acetate ethylene (VAE), i-vinyl acetate versatate (VAc / VeoVa), i-acrylics, kunye nezinye ii-copolymers. Ezi polymers zikhethwa ngokusekelwe kwiipropati zabo ezithile kunye nezicelo ezijoliswe kuzo.

Nazi ezinye iimpawu eziphambili kunye neepropathi zepolymer powder ephinda ihlakazeka:

1. Ukuqulunqwa kwefilimu: Xa ixutywe namanzi, iinqununu ze-RPP ziphinde zisasazeke kwaye zenze ifilimu ye-polymer eguquguqukayo xa yomiswa. Le filimu ibonelela ngokunamathela, ukudibanisa, kunye nokuqina kwii-substrates ezahlukeneyo, ezifana nekhonkrithi, i-mortar, i-adhesive tile, kunye neengubo.
2. Ukubambelela: I-RPP iphucula ukubambelela phakathi kwezinto ezahlukeneyo, kubandakanywa i-substrates kunye neengubo, iileyile kunye ne-adhesives, kunye neefayili kunye nezibophelelo. Iphucula amandla ebhondi kwaye inqande ukunyibilika okanye ukukhutshwa kwezinto ngokuhamba kwexesha.
3. Ukuguquguquka: I-RPP inika ukuguquguquka kweengubo, i-adhesives, kunye ne-mortars, ezivumela ukuba zifake ukunyakaza kwe-substrate, ukwandiswa kwe-thermal, kunye nezinye iingcinezelo ngaphandle kokuqhekeka okanye ukungaphumeleli. Le propati ibalulekile ekugcineni ingqibelelo yezinto ezisetyenzisiweyo.
4. Ukuchasana naManzi: I-RPP iphucula ukuxhathisa kwamanzi ekubunjweni, okwenza kube lula kwiindawo zangaphandle okanye ezimanzi. Inceda ukuthintela ukungena komswakama kwaye ikhusela ama-substrates angaphantsi kumonakalo.
5. Ukuqina: I-RPP iphucula ukuqina kunye nemozulu yezixhobo ngokuphucula ukuxhathisa kwimitha ye-UV, ukuvezwa kweekhemikhali, ukuqhawuka kunye nokuguga. Yandisa ubomi bezinto zokugquma, i-adhesives, kunye nodaka, ukunciphisa iimfuno zokugcinwa kunye neendleko.
6. Ukusebenza: I-RPP iphucula ukusebenza kunye nokuqhubekeka kokuqulunqwa ngokuphucula ukuhamba, ukulinganisa, kunye nokusabalalisa. Iqinisekisa ukugubungela okufanayo, ukusetyenziswa kakuhle, kunye nokusebenza okuhambelanayo kwezinto ezisetyenzisiweyo.
7. Ulawulo lweRheology: I-RPP isebenza njenge-rheology modifier, echaphazela i-viscosity, i-thixotropy, kunye ne-sag resistance of formulations. Inceda ukwandisa iipropati zesicelo kunye nokusebenza kweengubo, i-adhesives, kunye nodaka.
8. Ukuhambelana: I-RPP iyahambelana noluhlu olubanzi lwezinye izongezo, iifayili, ii-pigments, kunye nezibophelelo eziqhelekileyo ezisetyenziswa ekuqulunqweni. Ayichaphazeli kakubi iipropati okanye ukusebenza kwamanye amacandelo, ukuqinisekisa ukuzinza kunye nokuhambelana.

I-polymer powder ye-redispersible ifumana ukusetyenziswa ngokubanzi kwizicelo zokwakha, kubandakanywa i-adhesives ye-tile, i-samente-based mortars, i-self-leveling compounds, i-membrane yokukhusela amanzi, kunye nokulungiswa kodaka. Ikwanayo nezicelo kwizinto zokwaleka, izinto zokuncamathelisa, izitywini, iingubo, kunye namashishini ephepha, igalelo ekusebenzeni kunye nokuqina kwezinto ezahlukeneyo kunye neemveliso.
