Kedu ihe bụ powders latex na-agbanwe agbanwe?

Redispersible latex ntụ ntụ (RLP), makwaara dị ka redispersible polymer ntụ ntụ (RPP), bụ free-eru, mmiri na-ekesa ntụ ntụ nwetara site ịgba-ihicha a polymer latex emulsion. Ọ nwere ihe mejupụtara polymer, na-enwekarị ihe owuwu isi, yana mgbakwunye dị iche iche dị ka colloid nchebe, plasticizers, dispersants, na ndị na-egbochi ụfụfụ. Emebere RLP iji melite arụmọrụ na njirimara nke ihe cimenti, gụnyere adhesives, mortars, renders, na mkpuchi, site n'ịkwalite adhesion, mgbanwe, nkwụsị mmiri, ịrụ ọrụ na ịdịte aka.

Usoro mmepụta nke uzuzu latex redispersible gụnyere ọtụtụ usoro:

1. Polymer Emulsion Production: Usoro na-amalite site na mmepụta nke emulsion polymer site na polymerization nke monomers dị ka vinyl acetate, ethylene, acrylic esters, ma ọ bụ styrene-butadiene n'ihu ndị surfactants, emulsifiers, na stabilizers. A na-eme mmeghachi omume emulsion polymerization n'ime mmiri n'okpuru ọnọdụ a na-achịkwa iji mepụta mgbasa nke latex kwụsiri ike.
2. Ịsa ahịhịa: A na-edobe emulsion polymer ka ọ na-asachapụ, usoro ebe a na-etinye emulsion n'ime obere ụmụ irighiri mmiri ma weba ya n'ime mmiri ikuku na-ekpo ọkụ n'ime ụlọ ihicha. Ngwa ngwa ikuku nke mmiri sitere na ụmụ irighiri mmiri na-eduga n'ịmepụta ihe siri ike, nke a na-anakọta dị ka ntụ ntụ akọrọ na ala nke ụlọ ihicha. N'oge ihicha ịgba, ihe mgbakwunye dị ka colloid nchebe na plasticizers nwere ike itinye n'ime ahụ polymer iji meziwanye nkwụsi ike na arụmọrụ ha.
3. Ọgwụgwọ dị n'elu: Mgbe ihicha mmiri, ntụ ntụ latex na-agbanwe agbanwe nwere ike nweta ọgwụgwọ elu iji gbanwee njirimara ya na njirimara arụmọrụ ya. Ngwọta dị n'elu nwere ike ịgụnye itinye ihe mkpuchi ọzọ ma ọ bụ ntinye ihe mgbakwunye na-arụ ọrụ iji kwalite nrapado, nkwụsị mmiri, ma ọ bụ ndakọrịta na ihe ndị ọzọ na nhazi cimentious.
4. Nkwakọ ngwaahịa na Nchekwa: A na-akwakọba ntụ ntụ latex ntụ ntụ ikpeazụ n'ime akpa ma ọ bụ arịa na-eguzogide mmiri iji chebe ya pụọ ​​na mmiri na mmetọ gburugburu ebe obibi. Nkwakọ ngwaahịa kwesịrị ekwesị na ọnọdụ nchekwa dị mkpa iji nọgide na-adị mma na nkwụsi ike nke ntụ ntụ na oge.

Uzuzu uzuzu a na-emegharị emegharị na-achacha ọcha ma ọ bụ na-acha ọcha na agba ma nwee nkesa nha nha dị mma, sitere na micrometer ole na ole ruo iri iri nke micrometers. Ọ bụ ngwa ngwa dispersible na mmiri na-etolite anụ emulsions ma ọ bụ dispersions, nke nwere ike mfe weba n'ime cementity formulations n'oge agwakọta na ngwa. A na-eji RLP eme ihe n'ọtụtụ ebe na ụlọ ọrụ ihe owuwu dị ka ihe mgbakwunye dị iche iche iji melite arụmọrụ, ịrụ ọrụ na ịdịte aka nke ihe ụlọ na nrụnye dị iche iche.
