Kedu ihe bụ polymer powders redispersible?

A na-emegharị polymer powders (RPP) na-enweghị n'efu, ntụ ntụ ọcha na-emepụta site na ịgbasa polymer ihicha ma ọ bụ emulsions. Ha na-agụnye ihe ndị dị na polymer nke ejiri ihe nchebe na ihe mgbakwunye kpuchie ya. Mgbe agwakọtara ya na mmiri, ntụ ntụ ndị a na-agbasa ngwa ngwa ka ọ bụrụ emulsions polymer kwụsiri ike, na-eme ka ojiji ha dị n'ọtụtụ ngwa na-ewu, agba na mkpuchi, adhesives, na ụlọ ọrụ ndị ọzọ.

Ihe mejupụtara:

Ngwakọta nke powders polymer redisspersible na-agụnyekarị ihe ndị a:

1. Ihe ndị dị na polymer: Akụkụ bụ isi nke RPP bụ ihe ndị dị na polymer, nke sitere na polymer synthetic dị iche iche dị ka vinyl acetate-ethylene (VAE), ethylene-vinyl acetate (EVA), acrylics, styrene-butadiene (SB), ma ọ bụ polyvinyl acetate ( PVA). Ndị polymer a na-enye aka na ihe ndị a chọrọ na njirimara arụmọrụ nke ngwaahịa ikpeazụ.
2. Ndị na-echebe ihe nchebe: Iji gbochie ụmụ irighiri ihe polymer ka ọ ghara ịdị njọ n'oge nchekwa na njem, a na-ejikarị ihe nchebe dị ka polyvinyl mmanya (PVA) ma ọ bụ cellulose ethers. Ndị ọrụ ndị a na-eme ka ihe ndị dị na polymer kwụsie ike ma hụ na ha redispersibility na mmiri.
3. Plasticizers: Enwere ike ịgbakwunye ihe mkpuchi plastik iji kwalite mgbanwe, ịrụ ọrụ, na nrapado nke RPP. Ihe mgbakwunye ndị a na-enyere aka ịkwalite arụmọrụ nke ihe ndị dị na polymer na ngwa dị iche iche, karịsịa na mkpuchi na-agbanwe agbanwe, adhesives, na sealants.
4. Ihe ndochi na ihe mgbakwunye: Dabere na ngwa achọrọ, ihe ndochi, pigmenti, ndị na-agafe agafe, ndị na-agba mmiri na ihe mgbakwunye ndị ọzọ nwere ike itinye n'ime usoro RPP iji kwalite akụrụngwa ha ma ọ bụ nye ọrụ ụfọdụ.

Njirimara na njirimara:

Polymer powders a na-emegharị emegharị na-egosipụta ọtụtụ njirimara na njirimara na-eme ka ha dị iche iche ma jiri ya mee ihe na ụlọ ọrụ dị iche iche:

1. Redispersibility: RPP ngwa ngwa gbasasịa na mmiri na-etolite ike polymer emulsions ma ọ bụ dispersions, ikwe maka mfe incorporation n'ime formulations na ụdi ngwa.
2. Ikike imepụta ihe nkiri: Mgbe a gbasasịrị n'ime mmiri ma tinye ya n'elu, RPP nwere ike imepụta ihe nkiri dị gịrịgịrị, na-aga n'ihu mgbe nkụ. Ihe nkiri ndị a na-eme ka adhesion, ịdịte aka, na iguzogide ihu igwe na mkpuchi, ihe mkpuchi na mkpuchi.
3. Nkwado emelitere: RPP na-eme ka njikọ dị n'etiti ihe mkpuchi na mkpuchi, ngwa agha, ma ọ bụ adhesives, na-ebute njikọ siri ike na ịrụ ọrụ nke ọma na ihe owuwu na ụlọ.
4. Njide mmiri: Ọdịdị hydrophilic nke RPP na-enyere ha aka ịbanye na ijigide mmiri n'ime usoro nhazi, na-agbatị hydration na imeziwanye ọrụ, oge na-emeghe, na adhesion na ngwa ngwa na ngwa ntanye tile.
5. Mgbanwe na ike siri ike: Ihe ndị RPP gbanwere na-egosipụta mmụba dị ukwuu, ngbanwe, na ike siri ike, na-eme ka ha na-eguzogide mgbawa, nrụrụ, na mmebi mmetụta.
6. Mgbochi ihu igwe: RPP na-eme ka nguzogide ihu igwe na ịdịte aka nke mkpuchi, mkpuchi, na mkpuchi mmiri, na-enye nchebe na-adịgide adịgide megide radieshon UV, mmiri mmiri, na ihe gburugburu ebe obibi.

Ngwa:

Polima ntụ ntụ na-agbanwe agbanwe na-achọta ngwa n'ọtụtụ ụlọ ọrụ na ngwaahịa, gụnyere:

• Ihe owuwu: ihe mgbochi tile, ngwa agha, grouts, mkpuchi mmiri na-ekpuchi mmiri, ogige na-edozi onwe ya, na mkpuchi mkpuchi na imecha (EIFS).
• Agba na mkpuchi: Agba dị n'èzí, mkpuchi ederede, plasta ịchọ mma, na mkpuchi ụlọ.
• Adhesives na Sealants: Adhesives tile, crack fillers, caulks, sealants na-agbanwe agbanwe, na nrapado nwere mmetụta nrụgide.
• Ngwongwo akwa: mkpuchi akwa, ihe na-emecha, na ogige nha.

polymer powders redispersible bụ ihe dị iche iche na multifunctional na-eji eme ka arụmọrụ, ịdịte aka, na mgbanwe nke ngwaahịa dị iche iche na mmepụta ihe na-ewu, agba na mkpuchi, adhesives, textiles, na ụlọ ọrụ ndị ọzọ.
