I-RDP yodaka olungangeni manzi

Inokuphinda ihlakazweipolymer powder RDP/VAEyi-emulsion yepolymer eye yatyhutyha inkqubo yokumisa echanekileyo yokutshiza (kunye nokukhetha izongezo ezifanelekileyo)Ipolima yomgubo. Xa i-polymer ipowder eyomileyo idibana namanzi, iba yi-emulsion kwaye inokuphinda ikhutshwe emanzini kwinkqubo yokumisa udaka kunye nokuqina, ukuze iinqununu ze-polymer zenze isakhiwo sezinto ze-polymer kudaka, olufana nenkqubo yesenzo se-polymer emulsion kunye ne-polymer emulsion. idlala indima yohlengahlengiso kudaka lwesamente. Udaka olomileyo lwe-emulsion lubizwa ngokuba ngudaka olomileyo (owaziwa ngokuba ngumxube owomileyoed udaka, udaka lokuxuba owomileyo).

Ngenxa yokuba i-powder eyomileyo ayifuni ukuba ithathelwe ingqalelo njengolungiselelo lwe-polymer emulsion, ingxaki yokuzinza, umlinganiselo omncinci wokongeza udaka unokufezekisa umsebenzi ofunekayo, kwaye ungcono kunokuba i-emulsion ilula ukupakisha, ukugcinwa, ukuthutha kunye nokubonelela, i-antifreeze kunye akukho ukungunda, iintsholongwane, kunye nesamente nesanti esele ixutywe eyenziwe ngecandelo elinye iimveliso ukupakishwa ukongeza iingenelo ukusetyenziswa kwamanzi. Xa igalelwe, isanti, isamente, umgubo welatex owomileyo kunye nezinye izongezo ziyaxutywa kwaye zipakishwe kwangethuba, kwaye udaka olomileyo olunokusebenza ngcono lunokwenziwa ngokukhawuleza ngokugalela umlinganiselo othile wamanzi kulwakhiwo lwentsimi. Undoqo we-emulsion wokulungiselela umgubo owomileyo ulele kwi-particle size ye-polymer particles efana ne-original emulsion polymer particles okanye i-particle size dispersion. Ukongeza umlinganiselo othile colloid zokhuselo ezifana polyvinyl utywala emulsion, ukuzeipolymer powder RDP/VAEinokuphinda isasazwe kwi-emulsion xa idibana namanzi,ipolymer powder RDP/VAEbabe nokukhubazeka okulungileyo kuphela ukuze kuqinisekiswe ukusebenza kakuhle.ipolymer powder RDP/VAEekhoyo ngokusasazwa idla ngokuba ngumgubo omhlophe.

Izithako zayo ziquka:

I-polymer resin: ibekwe kwindawo engundoqo yei-polymer powder enokuchithwa kwakhonaamasuntswana, ikwalelona candelo liphambili lokuphinda lihlakazweipolymer powder RDP/VAEdlala indima.

Ukongeza (ngaphakathi) : ngokubambisana ne-resin ukuguqula i-resin.

I-additive (yangaphandle) : izinto ezongezelelweyo zongezwa ukwandisa ngakumbi iipropathi zokuphinda zihlakazweipolymer powder RDP/VAE.

I-colloid ekhuselayo: Umaleko we-hydrophilic wemathiriyeli esongelwe kumphezulu wezinto ezinokuphinda zihlakazweipolymer powder RDP/VAEamasuntswana. Uninzi lwe-colloid ekhuselayo ye-dispersibleipolymer powder RDP/VAEyi-polyvinyl alcohol.

I-Anti-Caking agent: i-fine mineral filler, isetyenziselwa ngokukodwa ukukhusela i-cakingi-polymer powder enokuchithwa kwakhonakwinkqubo yokugcina kunye nokuthutha kunye nokuququzelela ukuhamba kwei-polymer powder enokuchithwa kwakhona(lahla kwingxowa yephepha okanye kwimoto yetanki).
