Redispersible ufa ndi ufa wopangidwa ndi kutsitsi kuyanika polima emulsion, amatchedwanso youma ufa labala. Ufa uwu ukhoza kuchepetsedwa mwachangu kukhala emulsion mutalumikizana ndi madzi, ndikusunganso zomwezo monga emulsion yoyambirira, ndiye kuti, kanema ipangidwe madzi atayamba kutuluka. Kanemayo ali ndi kusinthasintha kwakukulu, kukana kwanyengo kwambiri komanso kukana kwabwino magawo osiyanasiyana. Chingwe chomangira chachikulu.

Redispersible latex ufa imagwiritsidwa ntchito makamaka kuminda zomangira monga kunja kukhoma, kuphatikiza matayala, mawonekedwe othandizira, gypsum, stucco jypsum, kumanga mkati ndi kunja kwa khoma putty, matope okongoletsera, ndi zina zambiri, zomwe zimakhala ndi malo ambiri ogwiritsira ntchito komanso msika wabwino ziyembekezo.

Kupititsa patsogolo ntchito ndikugwiritsira ntchito redispersible latex ufa kwathandizira kwambiri ntchito zamakono zopangira zinthu, kwathandizira kwambiri kuphatikiza, mgwirizano, mphamvu zosinthika, kukana, kutsutsana ndi abrasion, kulimba, etc. Pangani zomangamanga ndi zabwino zake komanso luso lapamwamba kwambiri kuti zitsimikizire kuti ntchito zomanga ndizabwino.

Redispersible ufa

Ma pomper omwe amagwiritsidwa ntchito kwambiri padziko lonse lapansi ndi awa: Vinyl Acetate Polyvinyl Acetate (VAC / E), Terpolymer wa Ethylene, Vinyl Chloride ndi Vinyl Laurate (E / VC / VL), Vinyl Acetate Ester ndi ethylene komanso mafuta apamwamba aciny vinyl ester ternary. Copolymer mphira ufa (VAC / E / VeoVa), mitundu itatuyi ya redispersible polymer ufa imalamulira pamsika, makamaka vinyl acetate ndi ethylene Copolymer mphira ufa wa VAC / E, Ali ndi udindo wotsogola padziko lonse lapansi, ndipo akuyimira umunthu waukadaulo womwe umayambiranso. ufa. Kuchokera pazochitika zaluso zogwiritsa ntchito ma polima osinthidwa ndi matope, ndi njira yabwino kwambiri yothetsera:

1. Ndi imodzi mwamapulogalamu ogwiritsira ntchito kwambiri padziko lapansi;

2. Kugwiritsa ntchito kwambiri ntchito yomanga;

3. Ikhoza kukwaniritsa zofunikira za rheological zomwe zimafunikira ndi matope (ndiye kuti, kuyenera kugwira ntchito);

4. Utomoni wa Polymeric wokhala ndi ma monomers ena umakhala ndi zinthu zotsika kwambiri (VOC) komanso mpweya wovuta;

5. Ili ndi mawonekedwe a UV kukana kwabwino, kutentha kwabwino kutentha ndi kukhazikika kwakanthawi;

6, ndi kukana kwakukulu kwa saponization;

7, ili ndi galasi lotentha kwambiri losintha magawo (Tg);

8. Ali ndi mgwirizano wabwino, wosasinthasintha komanso makina;

9. Ali ndi luso lalitali kwambiri pakupanga mankhwala ndi momwe angasungire kukhazikika kosungirako popanga zinthu zokhazikika;

10. Ndikosavuta kuphatikiza ndi colloid yoteteza (polyvinyl mowa) yogwira

Chithunzi 1 ndi chithunzi cha ufa wosinthika womwe umagulitsidwa pamsika

NKHANI redispersible ufa

1. Wowonjezera ufa ndi madzi osungunuka omwe amasungunuka. Ndi Copolymer wa ethylene ndi vinyl acetate, wokhala ndi polyvinyl mowa monga choteteza choteteza.

2. VAE redispersible latex ufa ali ndi malo opanga mafilimu, 50% yankho lamadzi amapanga emulsion, ndikupanga filimu yonga pulasitiki atayikidwa galasi kwa maola 24.

3. Kanema wopangidwayo amakhala ndi kusintha kosiyanasiyana komanso kukana madzi. Itha kufikira mayiko.

4.Redispersible latex ufa imachita bwino kwambiri: imatha kulumikizana kwambiri komanso kugwira ntchito mwapadera, kulimbana ndi madzi bwino, kulimba kwambiri, ndikupatsitsani matope osagwirizana ndi alkali, omwe amatha kupititsa patsogolo kugundika kwa matope komanso mphamvu zakukula kuphatikizira kupulasitiki, kuvala kukana ndi workability, ali kusinthasintha wamphamvu matope mng'alu zosagwira.

Kugwiritsa ntchito ufa wovundikiranso wa ufa wouma pouma:

Mort Matope okumba matope ndi matope a pulasitala: Kuyambiranso ufa wa latex kumatha kusungunuka, kusungidwa kwa madzi ndikuwumitsa, komanso kulimba kwambiri, komwe kumatha kuthana ndikusokonekera komanso kulowa mkati mwa matope achikhalidwe. Ndi nkhani zina zabwino.

Mort Kudzimangirira matope ndi zinthu zakuthupi: Redispersible latex powder ili ndi mphamvu yayikulu, kulumikizana kwabwino, kulumikiza ndikufunika kusinthasintha. Kodi kusintha guluu wolimba, kumva kuwawa kukana ndi posungira madzi a zipangizo. Zimatha kubweretsa zabwino kwambiri m'miyambo, magwiridwe antchito komanso kugwiritsa ntchito bwino-bwino kwambiri pansi komanso matope oyaka.

Ad Zomatira zomata, zophatikizira matayala: Redispersible latex powder imakhala yolumikizira bwino, kusungira madzi bwino, nthawi yayitali yotseguka, kusinthasintha, kukana kugwedezeka komanso kukana kuzizira. Zimatha kubweretsa zomata kwambiri, kutsika kwakukulu komanso kuyendetsa bwino ntchito yomanga matani zomatira, zopendekera matayala komanso zomata.

Mort Matope osagwiritsidwa ntchito ndi madzi: Risis yotsekeranso ufa imathandizira kulumikizana kumagawo onse, imachepetsa zotanuka, imachulukitsa madzi, imachepetsa malowedwe am'madzi, komanso imapereka zinthu zogwiritsidwa ntchito kwambiri, kukana nyengo yayikulu komanso kukana kwamadzi ambiri. Ili ndi mphamvu yayitali yokhazikika yosindikiza ndi zosowa zamadzi ndi kukana kwamadzi.

◆ Matope oyika kunja kwa khoma: Redispersible emulsion powder kunja kwa khoma lakunja kutulutsa kachipangizo kumakulitsa kuphatikiza matope komanso mphamvu yomangirira ku bolodi yolowetsera, kuti mutha kufunafuna kutchinjiriza mukamachepetsa kugwiritsa ntchito mphamvu. Kuti mukwaniritse magwiridwe antchito, mphamvu zosinthika komanso kusinthasintha kwa zinthu zakunja zoumba, mutha kupanga kuti zinthu zanu zogulitsa zikhale ndi mgwirizano wabwino ndi mndandanda wazida zowonjezera ndi maziko. Nthawi yomweyo, zimathandizanso kukonza kukana kwa zovuta ndi kukhudzana kwa nkhope.

◆ Kukonza Mtondo: Redispersible latex powder imafunikira kusinthasintha, kuchepa, kulumikizana kwakukulu, kusinthasintha kwamphamvu ndi kulimba kwamphamvu. Pangani matope okonzedwa pazomwe zili pamwambapa kuti akonzeke konkire yopanga komanso yosapangika.

◆ Chithunzithunzi Chozungulira: Potumba ufa wofiyirira umagwiritsidwanso ntchito kuthira simenti, simenti yotsikira, njerwa ya mchenga komanso kuuluka njerwa, ndi zina zotere, kuthetsa vutoli kuti mawonekedwe ake ndiwosavuta kutsatira chifukwa cholowetsa madzi kwambiri kapena kusalala , ndipo pulasitala wosanjayo mulibe. Drum, kuswa, kusenda, etc. Zimapangitsa kuti kuphatikiza kumveke kwambiri, osavuta kugwa ndi kukana kwamadzi, komanso kutsokomola kwambiri. Ili ndi gawo lalikulu pakugwira ntchito kosavuta, zomanga zosavuta.

Redisersible ufa amagwiritsidwa ntchito makamaka mu:

Mkati wakunja ndi wakunja wa putty ufa, zomata za tiles, wothandizirana ndi matailosi, wothandizirana ndi ufa wowuma, kunja kwa khoma kutchingira matope, zida zodzikonzera nokha, kukonza matope, matope okongoletsera, matope osagwiritsidwa ntchito ndi madzi mkati mwake. Matope onsewa amagwiritsidwa ntchito pokonzetsa kulimba kwa matope a simenti, ndikuwapatsa kusinthasintha kwabwino komanso kulimba kwamphamvu kuti athe kukana ndikuchedwetsa kubwera kwa ming'alu yamatope a simenti. Chifukwa polima ndi matope zimapanga njira yolumikizirana, mawonekedwe opitilira polima amapangidwa mu pores, omwe amalimbitsa kulumikizana pakati pazamagawo ndikuletsa zina mwazotumbazo. Chifukwa chake, matope osinthika pambuyo pakuumitsa amakhoza bwino kuposa matope a simenti. Pakhala kusintha kwakukulu.
