Redispersible polima ufa ndi chowonjezera chofunikira chomwe chimagwiritsidwa ntchito muzopangira simenti kapena gypsum pamakampani omanga. Ufawu umapangidwa ndi kupopera-kuyanika kwa polymer dispersion, yomwe imapanga ufa wopanda pake womwe ukhoza kusakanikirana mosavuta ndi zosakaniza zina zowuma. Pali mitundu ingapo yosiyanasiyana ya ufa wa polima womwe umapezekanso, iliyonse ili ndi mawonekedwe ake komanso mawonekedwe ake. M'chigawo chino, tiwona mitundu yodziwika bwino ya ufa wa polima wopangidwanso.

1. Vinyl acetate-ethylene (VAE) redispersible polima ufa

VAE redispersible polima ufa ndi imodzi mwa mitundu yomwe imagwiritsidwa ntchito kwambiri ya ufa wa polima womwe umagwiritsidwanso ntchito pantchito yomanga. Zimapangidwa ndi polymerizing vinyl acetate ndi ethylene mu emulsion yochokera kumadzi, yomwe kenako imawumitsidwa kuti ipange ufa wosasunthika. VAE redispersible polima ufa amadziwika chifukwa chomamatira bwino, kusinthasintha, komanso kukana madzi, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito pazinthu zomwe zimakhala zolimba, monga kukonza konkire, zomatira matailosi, komanso kutsekereza kwakunja ndi makina omaliza (EIFS).

2. Vinyl acetate-based redispersible polima ufa

Vinyl acetate-based redispersible polima ufa amapangidwa ndi polymerizing vinyl acetate mu emulsion yochokera kumadzi, yomwe kenako imawumitsidwa kuti ipange ufa wopanda madzi. Mtundu uwu wa ufa wopangidwanso ndi polymer umadziwika chifukwa chomamatira bwino, kugwira ntchito, komanso kukana kuzizira, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito ngati pulasitala, stucco, ndi zokutira zokongoletsa.

3. Acrylic-based redispersible polima ufa

Acrylic-based redispersible polima ufa amapangidwa ndi polymerizing acrylic monomers mu madzi ozikidwa emulsion, amene kenaka utsi-zouma kuti apange ufa wopanda madzi. Acrylic-based redispersible polima ufa amadziwika chifukwa cha kukana madzi bwino, kumamatira, komanso kusinthasintha, kupangitsa kuti ikhale yabwino kugwiritsidwa ntchito ngati grout, kukonza konkire, ndi zomatira matailosi.

4. Styrene-butadiene-based (SBR) redispersible polima ufa

SBR redispersible polima ufa amapangidwa ndi polymerizing styrene ndi butadiene mu madzi-based emulsion, amene kenako kupopera-zouma kuti apange free oyenderera ufa. SBR redispersible polima ufa amadziwika chifukwa cha kusinthasintha kwake, kumamatira, komanso kukana madzi, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito ngati matope, grout, ndi kukonza konkire.

5. Ethylene-vinyl chloride (EVC) redispersible polima ufa

EVC redispersible polima ufa amapangidwa ndi polymerizing ethylene ndi vinilu mankhwala enaake mu emulsion madzi ofotokoza, amene kenako utsi-zouma kuti apange ufa wopanda-oyenda. EVC redispersible polima ufa amadziwika bwino kwambiri madzi kukana, adhesion, ndi kusinthasintha, kuupanga kukhala abwino kwa ntchito monga matailosi zomatira, kukonza konkire, ndi EIFS.

6. Redispersible polima ufa wokhala ndi wowuma wosinthidwa

Redispersible polima ufa ndi kusinthidwa wowuma amapangidwa ndi kuwonjezera kusinthidwa wowuma kwa madzi ofotokoza emulsion pamaso kupopera-kuyanika. Wowuma wosinthidwa amakhala ngati dispersant, kuthandiza kukhazikika emulsion ndi kusintha redispersibility wa ufa. Mtundu uwu wa ufa wopangidwanso wa polima umadziwika chifukwa chomamatira bwino, kugwira ntchito, komanso kukana madzi, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito ngati matope, grout, ndi pulasitala.

7. Redispersible polima ufa wokhala ndi cellulose ether

Redispersible polima ufa ndi mapadi ether amapangidwa powonjezera mapadi efa ku madzi ozikidwa emulsion pamaso kupopera-kuyanika. Ether ya cellulose imagwira ntchito ngati thickener, kumapangitsanso kugwira ntchito kwa ufa ndikuchepetsa kuchuluka kwa madzi ofunikira pakusakaniza. Mtundu uwu wa ufa wopangidwanso ndi polymer umadziwika chifukwa chomamatira bwino, kugwira ntchito bwino, komanso kusunga madzi, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito ngati zomatira matailosi, grout, ndi nembanemba za simenti zotsekera madzi.
