Katundu ndi kagwiritsidwe ntchito ka ufa wosinthika

Redispersible ufa

Redispersible latex ufa ndi kufalitsa kothira komwe kamapangidwa ndi ma polymer polymer emulsion mwa kupopera. Imakhala ndi kupatsika bwino ndipo ikhoza kuphatikizidwanso mu emulsion yokhazikika pambuyo kuwonjezera madzi. Ntchitoyi ndi yofanana ndendende ndi emulsion yoyamba. Chifukwa chake, zimatha kupanga matope apamwamba kwambiri osakanizika ndi matope.

Redispersible latex ufa ndikofunikira komanso kofunikira pophatikiza matope. Ikhoza kusintha magwiridwe antchito a matope, kuwonjezera mphamvu yamatope, kukonza kulumikizana kwamphamvu kwa matope kumagawo angapo, ndikuwongolera kusinthasintha komanso kupunduka kwa matope Kutsutsana, kulimbikira mphamvu, mphamvu yamphamvu, kukana kumva kuwawa, kulimba, kulumikizana ndi kusungira madzi , kugwira ntchito. Kuphatikiza apo, ufa wa latex wokhala ndi ma hydrophobic umatha kupangitsa matope kukhala opanda madzi.

Chithunzi 1 ndi chithunzi cha ufa wofiyiranso.

Redispersible lalabala ufa wa matope omata ndi kupaka pulasitala uli ndi kutayika kwabwino, kusungira madzi ndi kuzizira, komanso mphamvu yolumikizana, yomwe ingathetseretu kulimbana ndi kulowerera komwe kulipo mumtondo wachikhalidwe. vuto.

Zodzikongoletsera zokhazokha komanso pansi panu Zowonjezera ufa wa latex zimakhala ndi mphamvu zambiri, mgwirizano wabwino / zomatira komanso kusinthasintha kofunikira. 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.

Zomata zomata, mataulo olumikizana othandizira Redispersible latex ufa amakhala ndi zomatira zabwino, kusungidwa bwino kwa madzi, nthawi yayitali yotseguka, kusinthasintha, kukana kwa sag ndi kukana kwabwino. Zimatha kubweretsa zomata kwambiri, kutsika kwakukulu komanso kuyendetsa bwino ntchito yomanga matani zomatira, zopendekera matayala komanso zomata.

Matope osagwiritsidwa ntchito ndi madzi osachedwa kuwongolera ufa kumakulitsa kulumikizana kwa magawo onse, amachepetsa ma modulus, amawonjezera kusungunuka kwa madzi, amachepetsa malowedwe am'madzi, komanso amapereka zinthu mosinthika kwambiri, kukana kwanyengo ndi kukana kwamadzi ambiri Madzi ndi kukana kwamadzi kumafuna mphamvu yayitali kusindikiza dongosolo.

Mpanda wakunja wowotcha matope Redispersible emulsion ufa kukhoma lakunja kutulutsa masisitimu kumathandizira kuphatikiza matope komanso mphamvu yomangirira ku board yamagetsi yamafuta, kuti mutha kufunafuna kutchinjiriza ndikuchepetsa mphamvu yamagetsi. 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.

Chithunzi 2 ndi chithunzi cha ufa wonyezimira wa latex.

Kukonza Mtondo Redispersible lalabala ufa amafunika kusinthasintha, shrinkage, mkulu mgwirizano, abwino flexural ndi kwamakokedwe mphamvu. Pangani matope okonzedwa pazomwe zili pamwambapa kuti akonzeke konkire yopanga komanso yosapangika.

Matope a interfacial redispersible latex ufa amagwiritsidwa ntchito makamaka pothandiza konkriti, simenti yozunguliridwa, njerwa yamchenga yamchenga ndi kuwuluka njerwa. Kubowola, kukhalira, ndi zina. Zimapangitsa kuti kuphatikiza kumveke kwambiri, osavuta kugwa ndi kukana madzi, komanso kutsokomola kwambiri. Ili ndi gawo lalikulu pakugwira ntchito kosavuta, zomanga zosavuta.

Zida zopangidwa ndi ufa ndizosavuta pamsika, koma katundu wawo ndiwofanana. Zitha kufotokozedwa mwachidule motere:

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.

Zogulitsa zamtunduwu zimagwiritsidwa ntchito makamaka m'minda yomanga monga kukhoma kwanyumba, kupindika matayala, mawonekedwe othandizira, pulasitala womanga, pulasitala womanga, nyumba yomanga komanso kunja kwa khoma lamatayala, matope okongoletsera, ndi zina zambiri. ziyembekezo msika.

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.
