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 esetyenziswa kwi-latex powder edispersible i-polymer emulsion eyenziwa 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 e-dispersible incinci kakhulu, kwaye ukunamathela kwe-emulsion ye-acrylic imbi, kwaye ilungile. incamathele kudaka.Ukuphuculwa okwaneleyo kwimida yamandla okudibanisa 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.
