I-redispersible latex powder yipowder efunyenwe ngokutshiza-yomisa i-polymer emulsion kwaye emva koko yongeza izinto ezilungisiweyo, ezinokuthi zisasazwe kwakhona ukuze zenze i-emulsion xa idibana namanzi. I-redispersible latex powder isetyenziswa ikakhulu njengesongezelelo sodaka oluxubeneyo olomileyo, olunemisebenzi yokuphucula ukusebenza kodaka, ukuphucula ulwelo, ukuphucula ukubumbana, kunye nokwandisa amandla okudibanisa. Luhlobo olutsha lwemathiriyeli ehambelana nokusingqongileyo. Okwangoku, i-latex powder kufuneka yongezwe kwi-tile bonding, ukugquma udonga lwangaphandle, ukuzimela, i-putty powder, njl.
I-emulsion ye-polymer esetyenziswe kwi-latex powder ephinda iphindwe kwakhona i-polymer emulsion eyenziwe ngokudibanisa i-monomers enye okanye ezimbini kwi-vinyl acetate njenge-monomer e-China. Okwangoku, i-vinyl acetate-ethylene copolymer emulsion, i-vinyl acetate - Ikakhulu i-ethylene tertiary carbonate copolymer emulsion, izongezo ziya kongezwa kwi-latex powder eveliswe ukuphucula i-anti-caking kunye ne-dispersibility. Nangona kunjalo, ngenxa yesakhiwo se-vinyl acetate, amandla ayo okuqala kunye namandla okuphilisa amanzi awalungile ngokunamathela kwiibhodi zokugquma kunye ne-samente substrates.
I-emulsion ye-Acrylic inokumelana kakuhle namanzi kwaye isetyenziswa ngokubanzi kwishishini lezinto zokwakha, kodwa ukomisa kwayo ngokuthe ngqo kunye nenkqubo yokutshiza umgubo ikhulile, kwaye inxalenye yayo kwi-emulsion powder edispersible incinci kakhulu, kwaye ukunamathela kwe-emulsion ye-acrylic imbi, kwaye ilungile. incamathele kudaka. Ukuphuculwa okwaneleyo kumandla okubambisana kunciphisa ukusetyenziswa kwe-emulsions ye-acrylic.
Injongo yenoveli ye-acrylic latex powder kunye nendlela yokuyilungisa kukufumana iimveliso zomgubo we-latex kunye namandla aphezulu adibeneyo kunye nokunamathela okulungileyo.
1. I-powder ye-latex e-dispersible ine-cohesiveness egqwesileyo, enokuphucula ukudibanisa kwesakhiwo sodaka, ukuphucula ukudibanisa phakathi kodaka kunye nesiseko, kunye nokuphucula ukusebenza. Ifanelekile kwizixhobo zokwakha kunye nodaka olufuna amandla aphezulu okudibanisa. intsimi, ithemba lemarike libanzi.
2. Kwinkqubo yokuqulunqa i-latex powder edibeneyo, iindidi ze-emulsion ze-polymer ezisekelwe kwi-emulsion ye-acrylic zikhethwa kwaye zixutywe ngokomlinganiselo ofanelekileyo, onokunika umdlalo opheleleyo kwiinzuzo zabo, ukuphucula ukusebenza kwe-latex powder, kunye ukwandisa umda we powder latex. umda wesicelo.
3. Ekulungiseleleni i-latex powder edibeneyo, i-spray liquid ishushu ngokuthe ngqo ngokufudumeza kwe-intanethi, okuphucula ukuphinda kuphindwe kwakhona kwe powder latex.
4. Kwinkqubo yefomyula ye-latex powder ephindwe kabini, iindidi ezimbini zemixube ye-calcium carbonate, i-talcum powder, i-kaolin kunye ne-silicon dioxide zikhethwa njenge-anti-caking agents kunye nomlinganiselo omkhulu we-1: 1-2, ukwenzela ukuba i-latex powder. amasuntswana Ukusonga kufana ngakumbi kwaye ipropathi echasayo ye-latex powder iphuculwe.
5. Kwinkqubo yokuqulunqa i-latex powder, enye okanye umxube we-silicone defoamer kunye ne-mineral oil defoamer ikhethwa njenge-defoamer kwi-mass ratio ye-1: 1, ephucula ipropati yokwenza ifilimu ye-latex powder. iphucula amandla okubopha udaka.
6. Inkqubo yokulungiselela i-latex powder edibeneyo ilula kwaye kulula ukuyiqonda i-industrialization.
