Ndi zinthu ziti zamatope zomwe zitha kusinthidwa ndi ufa wa latex wopangidwanso?

Redispersible latex ufa amapangidwa ndi polima emulsion ndi kutsitsi kuyanika, wothira madzi mu matope simenti, emulsified ndi omwazikana m'madzi, ndiyeno regenerates khola polima emulsion. Pambuyo redispersible latex ufa ndi emulsified ndi omwazikana m'madzi, madzi amasanduka nthunzi , Pangani polima filimu mu matope kusintha katundu wa matope. Mitundu yosiyanasiyana ya latex yopangidwanso imakhala ndi zotsatira zosiyana pamatope owuma a ufa.

1. Kupititsa patsogolo kukana kwamphamvu, magwiridwe antchito ndi kuvala kukana kwa matope

Mtondowo umadzazidwa ndi matope a simenti amatope, kuphatikizika kwa matope a simenti kumakhala bwino, ndipo kukana kuvala kumakhala bwino. Pansi pa mphamvu yakunja, imatha kuyambitsa kumasuka popanda kuwonongedwa. Mapepala a polima amatha kusungidwa mu kasamalidwe ka matope a simenti.

2. Kupititsa patsogolo kumamatira kwa zomangamanga zamatope

Tinthu tating'onoting'ono ta polima timanyowetsa, kotero kuti zigawo ziwiri za matope a simenti zimatha kuyenda paokha. Kuonjezera apo, ufa wa rabara umakhala ndi mphamvu yopangira mpweya.

3. Kupititsa patsogolo mphamvu yolumikizirana yolumikizana ndi matope olumikizana

Monga organic mankhwala zomatira, redispersible latex ufa akhoza kupanga mkulu compressive mphamvu ndi compressive mphamvu pa matabwa osiyanasiyana. Zimagwira ntchito yofunikira kwambiri pakumangirira matope a simenti ndi zinthu zopangira mankhwala (m'mimba, bolodi lotsekereza lotsekereza) komanso pamwamba pa bolodi yoyeretsa. DEM zopangira ndi depilatory polima ufa amagwiritsidwa ntchito kwambiri mu machitidwe onse a simenti kasamalidwe ka matope kuti apititse patsogolo mgwirizano wa matope a simenti.

4. Limbikitsani kukalamba kwa matope, pewani kusungunuka kwamadzi, komanso kupewa matope a simenti kuti asang'ambe.

Redispersible latex ufa ndi utomoni wa thermoplastic wokhala ndi kusinthasintha kwabwino, zomwe zingapangitse matope kuthana ndi kuwonongeka komwe kumachitika chifukwa cha kutentha kwakunja ndi malo ozizira, ndikupewa ming'alu mumatope chifukwa cha kusintha kwa kutentha.

5. Wonjezerani hydrophobicity ya matope ndikuchepetsa chinyezi

The redispersible latex ufa ndi demulsified mu matope a simenti patsekeke ndi pamwamba wosanjikiza, ndi pepala polima si zophweka kubalalitsanso pambuyo mankhwala madzi, kutsekereza kulowerera madzi ndi kusintha impermeability. Ubweya wagalasi wopanda madzi uwu umakhala ndi zotsatira zabwino chifukwa cha luso lake lapadera lomwaza ufa wachilengedwe wa latex.

Waukulu ntchito redispersible latex ufa

Mkati ndi kunja kwa khoma putty ufa, matailosi zomatira, matailosi kuloza wothandizira, youma ufa mawonekedwe agent, kunja matenthedwe matope matope kwa makoma akunja, matope odziyimira pawokha, matope okonza, matope okongoletsera, matope osalowa madzi kunja kwa matenthedwe owuma osakaniza matope. 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 matope kusinthidwa pambuyo kuumitsa ndi bwino kuposa simenti matope. Pali kusintha kwakukulu.

Mankhwala katundu wa redispersible latex ufa

1. Limbikitsani mphamvu yopindika ndi mphamvu yopindika yamatope

Kanema wa polima wopangidwa ndi redispersible latex ufa amakhala ndi kusinthasintha kwabwino. Mafilimu amapangidwa mu mipata ndi pamwamba pa matope a simenti kuti apange malumikizidwe osinthika. Tondo la simenti lolemera komanso lophwanyika limakhala zotanuka. Tondo wowonjezeredwa ndi ufa wopangidwanso ndi latex umakhala wokwera kangapo pakulimba komanso kusinthasintha kuposa matope wamba.

2. Kupititsa patsogolo mphamvu zomangira ndi mgwirizano wamatope

Pambuyo redispersible latex ufa monga organic binder aumbike filimu, akhoza kupanga mkulu wamakomedwe mphamvu ndi kugwirizana mphamvu pa magawo osiyanasiyana. Zimagwira ntchito yofunikira pakumatira kwamatope kuzinthu zakuthupi (EPS, bolodi lotulutsa thovu) ndi magawo osalala apansi. Mafilimu opangidwa ndi mphira wa mphira wa polima amagawidwa mumatope onse ngati chinthu cholimbikitsa kuti awonjezere mgwirizano wa matope.

3. Kupititsa patsogolo kukana kwamphamvu, kulimba komanso kuvala kukana kwa matope

Tinthu tating'onoting'ono ta mphira timadzaza matope amatope, kuchuluka kwa matope kumawonjezeka, ndipo kukana kuvala kumatheka. Pansi pa mphamvu yakunja, idzatulutsa mpumulo popanda kuwonongedwa. Filimu ya polima ikhoza kukhalapo mpaka kalekale mumtondo.

4. Limbikitsani kusagwira ntchito kwa nyengo ndi kukana kuzizira kwamatope, ndikuteteza matope kuti asang'ambe

Redispersible latex ufa ndi utomoni wa thermoplastic wokhala ndi kusinthasintha kwabwino, zomwe zingapangitse matope kuti athane ndi kusintha kwa kuzizira kwakunja ndi chilengedwe chotentha, ndikuletsa bwino kuti matope asagwedezeke chifukwa cha kusintha kwa kutentha.

5. Sinthani hydrophobicity ya matope ndikuchepetsa kuyamwa kwamadzi

The redispersible latex ufa umapanga filimu pazitsulo ndi pamwamba pa matope, ndipo filimu ya polima sidzabalalitsa kachiwiri pambuyo pokumana ndi madzi, zomwe zimalepheretsa kulowetsedwa kwa madzi ndikupangitsa kuti zisawonongeke. Special redispersible latex ufa ndi hydrophobic kwenikweni, bwino hydrophobic kwenikweni.

6. Kupititsa patsogolo ntchito yomanga matope

Pali mafuta opangira mafuta pakati pa tinthu tating'ono ta polima mphira, kotero kuti zigawo zamatope zimatha kuyenda paokha. Pa nthawi yomweyo, ufa mphira ali ndi inductive zotsatira pa mpweya, kupereka matope compressibility ndi kupititsa patsogolo ntchito yomanga matope.
