Yintoni i-latex powder enokuphinda ihlakazwe?

I-redispersible latex powder, eyaziwa ngokuba yi-polymer powder okanye i-RDP, isithako esiphambili kwizinto zokwakha zanamhlanje, ngakumbi kwintsimi yodaka lomxube owomileyo.Ezi powders zisetyenziswa kakhulu kumashishini ahlukeneyo abandakanya ukwakhiwa, iipeyinti kunye neengubo, izinto zokuncamathelisa, amalaphu kunye namayeza, phakathi kwabanye.

1. Intshayelelo ye-latex powder ephinda ihlakazwe:
Redispersible latex powder ngumgubo wepolymer oqukuqelayo okhululekileyo ofunyenwe ngokutshiza ukomiswa kokusasazwa kwepolymer enamanzi.Iqukethe umxube weepolymers zokwenziwa, ngokuqhelekileyo i-vinyl acetate-ethylene (VAE) i-copolymer, kunye neentlobo ezahlukeneyo zokudibanisa ezifana ne-colloids yokukhusela, i-plasticizers, kunye ne-dispersants.Injongo ephambili ye-latex powder ehlaziywayo kukuphucula ukusebenza kwezinto zokwakha, ukunika iimpawu eziphambili ezifana nokubambelela, ukuguquguquka, ukuchasana kwamanzi kunye nokuqhubekeka.

2. Inkqubo yokwenziwa kwemveliso:
Ukuveliswa kwe-latex powder ekwazi ukuphinda isebenze kubandakanya amanyathelo amaninzi abalulekileyo:

A. Ukwenziwa kwepolymerization:
Inkqubo iqala nge-emulsion polymerization ye-monomers efana ne-vinyl acetate kunye ne-ethylene phambi kwabaqalisi kunye ne-surfactants.Eli nyathelo livelisa i-aqueous dispersion ye-polymer particles.

b.Ukutshiza ukomisa:
I-aqueous dispersion iye ke itshizwe-yomiswe, ifakwe kwi-athomu ibe ngamathontsi kwaye yomiswe ngokukhawuleza kusetyenziswa umoya oshushu.I-powder ephumayo iqukethe iincinci ezincinci ze-polymer ezifakwe kwi-colloid ekhuselayo.

C. Emva kokulungiswa:
Iinkqubo emva kokulungiswa emva koko zinokuthi zenziwe ukunyusa iimpawu ze powder.Oku kunokubandakanya ukomisa okongeziweyo, ukuguqulwa komphezulu okanye ukongezwa kwezongezo.

3. Ukwakheka:
I-latex powder ekwazi ukuphinda isetyenziswe idla ngokuba nezi zithako zilandelayo:

IiPlastiki: Ukuphucula ukuguquguquka kunye nokuqhubekeka kwemveliso yokugqibela.

I-Disperpersants: Iipowder zokunceda zisasazeke emanzini kwaye ziququzelele ukuhlanganiswa kwazo kwiifomyula.

4. Ukusebenza kunye nokusebenza:
I-latex powder enokuphinda isetyenziswe inika iipropathi ezininzi eziphambili kwizinto zokwakha, kubandakanya:

Ukubambelela: Ukwandisa amandla ebhondi, ngakumbi kwi-mortar kunye ne-adhesives tile.

Ukuguquguquka: Ukuphucula ukuchasana nokuqhekeka kunye nokuguqulwa, okubalulekileyo kwi-flexible membranes waterproofing membranes kunye ne-caulk.

Ukumelana naManzi: Ukubonelela ngokhuseleko kumswakama kunye nokuphucula ukuqina kwiindawo ezimanzi.

Ukuqhubekeka: Ukuphucula ukuphatha kunye neempawu zokusetyenziswa komxube owomileyo wokuxutywa.

5. Isicelo:
I-latex powder ephinda isetyenziswe isetyenziswa ngokubanzi kumashishini ahlukeneyo:

a.melana:
I-Tile Adhesives kunye neGrouts: Ukuphucula ukubambelela kunye nokuguquguquka ekufakeni i-tile.
I-Insulation yangaphandle kunye ne-Finishing Systems (EIFS): Ukuphucula ukusebenza kwe-EIFS ngokubonelela ukuguquguquka kunye nokumelana nokuqhekeka.
Udaka kunye neeplasta: Ukuphucula ukomelela kweqhina, ukusebenza kunye nokuxhathisa kwamanzi kwiidaka zesamente kunye neeplasta.
I-self-Leveling Compound: Yongeza ukuhamba kunye nokubambelela kwi-self-leveling flooring compounds.
b.Iipeyinti kunye neeNqaku:
Isetyenziswe njengefilimu yangaphambili kunye ne-binder kwiipeyinti ezisekelwe emanzini kunye neengubo zokuphucula ukubambelela kunye nokuqina.
C. Ukuncamathelisa:
