Kugwiritsa Ntchito Wamba kwa Redispersible Polymer Powders

Ufa wa mphira umapangidwa ndi kutentha kwambiri, kuthamanga kwambiri, kuyanika kutsitsi ndi homopolymerization ndi mitundu yosiyanasiyana yolimbitsa ma micropowders, yomwe imatha kupititsa patsogolo luso lolumikizana komanso kulimba kwamatope, ndipo imakhala ndi ntchito yabwino yomanga yotsutsa kugwa, kusunga madzi. ndi thickening, madzi kukana ndi amaundana-thaw kukana , Kutentha kwabwino kukana kukalamba, zosakaniza zosavuta, zosavuta kugwiritsa ntchito, zomwe zimatilola kupanga matope apamwamba osakaniza owuma. Ntchito zodziwika bwino za ufa wa polima wopangidwanso ndi:

zomatira: zomatira matailosi, zomatira zomangira ndi kutsekereza mapanelo;

Dongo la khoma: matope otsekemera kunja, matope okongoletsera;

Mtondo wapansi: matope odzipangira okha, matope okonzera, matope osalowa madzi, mawonekedwe a ufa wouma;

Ufa wokutira: mkati ndi kunja khoma ndi denga putty ufa, latex ufa kusinthidwa laimu-simenti pulasitala ndi utoto;

Kudzaza kolumikizana: tile grout, matope olowa.

Redispersible latex ufa sayenera kusungidwa ndi kunyamulidwa pamodzi ndi madzi, zomwe zimachepetsa ndalama zoyendera; ili ndi nthawi yayitali yosungira, ndi antifreeze, ndipo ndi yosavuta kusunga; paketiyo ndi yaying'ono, yopepuka kulemera kwake, komanso yosavuta kugwiritsa ntchito; imatha kusakanikirana ndi ma hydraulic binders, opangidwa The synthetic resin modified premix ingagwiritsidwe ntchito powonjezera madzi, zomwe sizimangopewa zolakwika pakusakaniza pamalo omanga, komanso zimathandizira chitetezo cha kayendetsedwe ka mankhwala.

Mumtondo, ndikuwongolera brittleness, zotanuka modulus ndi zofooka zina za matope a simenti, ndikupangitsa kuti matope a simenti akhale osinthika bwino komanso olimba omangika, kuti athe kukana ndikuchedwetsa kuphulika kwa matope a simenti. Popeza polima ndi matope kupanga interpenetrating maukonde dongosolo, mosalekeza polima filimu aumbike mu pores, amene kumalimbitsa mgwirizano pakati pa aggregates ndi midadada ena pores mu matope, kotero kusinthidwa matope pambuyo kuumitsa ndi bwino kuposa simenti matope. zakhala bwino.

The redispersible latex ufa umabalalika kupanga filimu ndikuchita monga kulimbikitsa ngati chomatira chachiwiri; colloid yoteteza imatengedwa ndi matope (sidzawonongedwa ndi madzi pambuyo pa kupanga filimu, kapena "kubalalitsidwa kwachiwiri"); filimu yopangira polima utomoni Monga kulimbikitsa zinthu, izo zimagawidwa mu matope dongosolo lonse, potero kuwonjezera kugwirizana kwa matope.
