RDP ee Hoobiyaha aan biyuhu lahayn

Dib loo kala diri karobudada polymer RDP/VAEwaa emulsion polymer ah oo soo maray habka qalajinta buufinta saxda ah (iyo sidoo kale xulashada waxyaabaha lagu daro ee ku habboon) polymer budada ah.Marka budada qallalan ee polymerku ay la kulanto biyaha, waxay noqotaa emulsion oo mar labaad lagu fuuq-baxo karaa habka dejinta hoobiye iyo adkeynta, si ay qaybaha polymerka u sameeyaan qaab-dhismeedka shay polymer ee hoobiye, taas oo la mid ah habka ficilka ee emulsion polymer iyo wuxuu door wax ka beddel ah ka ciyaara hoobiye sibidhka.Emulsion hoobiyeyaasha wax laga beddelay waxaa loo yaqaan hoobiye qalalan (sidoo kale loo yaqaan isku dhafka qalalaned hoobiye, hoobiye qalalan qalalan).

Sababtoo ah budada qalalan uma baahna in loo tixgeliyo sida diyaarinta emulsion polymer, dhibaatada xasiloonida, qadar yar oo ah hoobiye lagu daro ayaa gaari kara waxqabadka loo baahan yahay, waana ka fiican yahay emulsion waa sahlan tahay baakadaha, kaydinta, gaadiidka iyo sahayda, antifreeze iyo caariyaysi la'aan, bakteeriya, iyo sibidh iyo ciid diyaarsan oo laga sameeyay baakado hal qaybood ka kooban ayaa ku kordhinaya faa'iidooyinka isticmaalka biyaha.Marka la marsado, ciidda, sibidhka, budada qalalan ee cinjirka ah iyo waxyaabaha kale ee lagu daro ayaa la isku daraa oo si fiican hore loogu sii shubayaa, hoobiye engegan oo leh waxqabad wanaagsan ayaa isla markiiba la samayn karaa iyadoo lagu darayo qadar biyo ah dhismaha beerta.Xudunta u ah diyaarinta budada qalalan ee emulsion waxay ku jirtaa cabbirka walxaha polymer-ka ee la midka ah walxaha polymer-ka emulsion asalka ah ama kala firdhinta cabbirka walxaha.Si aad ugu darto qadar gaar ah oo kolloid ilaalin ah sida alkolada polyvinyl ee emulsion-ka, sibudada polymer RDP/VAEdib ayaa loo kala firdhi karaa emulsion marka biyaha la taabto,budada polymer RDP/VAEkaliya leeyihiin kala daadsanaan wanaagsan si loo hubiyo waxtarka ugu fiican.budada polymer RDP/VAEkala firidhsan inta badan waa budo cad.

Waxyaabaha ay ka kooban tahay waxaa ka mid ah:

Polymer resin: wuxuu ku yaalaa qaybta xudunta u ahbudada polymer dib loo cusboonaysiin karoQaybaha, sidoo kale waa qaybta ugu muhiimsan ee dib loo cusboonaysiin karobudada polymer RDP/VAEdoor ka ciyaara.

Isku-darka (gudaha): iyadoo lala kaashanayo resinka si loo beddelo xabagta.

Wax-qabad (dibadeed): walxo dheeraad ah ayaa lagu daraa si loo sii ballaariyo sifooyinka dib loo kala diri karobudada polymer RDP/VAE.

Colloid difaac: lakabka walxaha hydrophilic oo ku duuduuban dusha sare ee dib loo firdhi karobudada polymer RDP/VAEqaybo.Inta badan kolloid-ka difaaca ee dib loo firdhi karobudada polymer RDP/VAEwaa khamriga polyvinyl.

Wakiilka-caking-ka: buuxinta macdanta wanaagsan, badiyaa loo isticmaalo si looga hortago in la keegabudada polymer dib loo cusboonaysiin karohabka kaydinta iyo gaadiidka iyo fududaynta socodkabudada polymer dib loo cusboonaysiin karo(ka soo tuur bacda warqadda ama gaariga taangiga).
