Kulankhula za gawo la redispersible latex ufa mumatope osiyanasiyana

The redispersible latex ufa ukhoza kufalikira mofulumira mu emulsion pambuyo pokhudzana ndi madzi, ndipo uli ndi zinthu zofanana ndi emulsion yoyamba, ndiko kuti, filimu imatha kupangidwa madzi atatha. Kanemayu ali kusinthasintha mkulu, mkulu nyengo kukana ndi kukana zosiyanasiyana Mkulu adhesion kwa magawo. Kuphatikiza apo, ufa wa hydrophobic latex umapangitsa kuti matopewo asalowe madzi.

Redispersible latex ufa umagwiritsidwa ntchito makamaka mu:

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.

Udindo wa ufa wa latex wopangidwanso mumatope uli muzinthu izi:

1. Limbikitsani mphamvu yopondereza ndi mphamvu yosunthika yamatope.

2. Kuphatikizika kwa ufa wa latex kumawonjezera kutalika kwa matope, potero kumapangitsa kuti matopewo akhale olimba, komanso amapatsa matopewo kukhala ndi zotsatira zabwino zobalalika.

3. Kupititsa patsogolo mgwirizano wamatope. Njira yolumikizirana imatengera kutengera ndi kufalikira kwa ma macromolecules pamtunda womata. Panthawi imodzimodziyo, ufa wa latex uli ndi mphamvu zinazake ndipo umalowa bwino pamwamba pa zinthu zoyambira ndi cellulose ether, kotero kuti zinthu zapansi pamunsi ndi pulasitala yatsopano zili pafupi, potero kuwongolera Adsorption kumawonjezera ntchito yake.

4. Chepetsani zotanuka modulus matope, kusintha mapindikidwe luso ndi kuchepetsa ang'onoang'ono chodabwitsa.

5. Kupititsa patsogolo kukana kwamatope. Kusintha kwa kukana kuvala kumakhala makamaka chifukwa cha kukhalapo kwa guluu wambiri pamwamba pa matope. Guluu ufa umakhala ngati chomangira, ndipo mawonekedwe a omentum opangidwa ndi guluu ufa amatha kudutsa mabowo ndi ming'alu ya matope a simenti. Imapititsa patsogolo mgwirizano pakati pa zinthu zoyambira ndi zinthu za simenti za hydration, potero zimawonjezera kukana.

6. Perekani matope kukana bwino kwa alkali.

7. Kupititsa patsogolo mgwirizano wa putty, kukana kwambiri, kukana kwa alkali, kukana kuvala, ndikuwonjezera mphamvu yosinthasintha.

8. Sinthani kusalowa madzi ndi permeability wa putty.

9. Sinthani kasungidwe ka madzi a putty, onjezani nthawi yotseguka, ndikuwongolera magwiridwe antchito.

10. Sinthani kukana kwamphamvu kwa putty ndikuwonjezera kulimba kwa putty.

Redispersible latex ufa amapangidwa ndi polima emulsion ndi kupopera kuyanika. Pambuyo kusakaniza ndi madzi mu matope, ndi emulsified ndi omwazika m'madzi kuti apangenso khola polima emulsion. Pambuyo redispersible latex ufa ndi emulsified ndi omwazika m'madzi, madzi amasanduka nthunzi. Filimu ya polima imapangidwa mumatope kuti ipititse patsogolo zinthu zamatope. Mitundu yosiyanasiyana ya latex yopangidwanso imakhala ndi zotsatira zosiyana pamatope owuma a ufa.

Mankhwala katundu wa redispersible latex ufa

── Sinthani mphamvu yopindika ndi mphamvu yopindika ya matope

Filimu ya polima yopangidwa ndi redispersible polima ufa imakhala yabwino kusinthasintha. 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.

── Limbikitsani mphamvu zomangira ndi kulumikizana kwamatope

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 polymer latex ufa amagawidwa mumatope onse monga kulimbikitsanso kuonjezera mgwirizano wa matope.

──Sinthani kukana kwamphamvu, kulimba komanso kulimba kwa matope

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

──Sinthani kukana kwanyengo komanso kukana kuzizira kwamatope, ndikuletsa 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.

── 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.

── Kupititsa patsogolo ntchito yomanga matope&

Pali mphamvu yothira mafuta pakati pa tinthu tating'onoting'ono ta polima latex, kotero kuti zigawo zamatope zimatha kuyenda paokha. Panthawi imodzimodziyo, ufa wa latex umakhala ndi zotsatira zochititsa chidwi pamlengalenga, zomwe zimapangitsa kuti matope apangidwe komanso kupititsa patsogolo ntchito yomanga matope.

Kugwiritsa ntchito mankhwala a redispersible latex powder

1. Njira yotchinjiriza kunja:

Zomatira matope: onetsetsani kuti matopewo amangirira khoma ku bolodi la EPS. Limbikitsani mphamvu ya mgwirizano.

Pulata matope: onetsetsani mphamvu zamakina, kukana kwa ming'alu, kulimba komanso kukana kwamakina amagetsi otenthetsera matenthedwe.

2. Zomatira matailosi ndi zomangira:

Zomatira za matailosi: Amapereka chomangira champhamvu kwambiri kumatope, kupatsa matope kusinthasintha kokwanira kuti athe kutengera ma coefficients osiyanasiyana akukula kwamafuta a gawo lapansi ndi matailosi.

Sealant: Pangani matope kukhala osasunthika bwino ndikuletsa kulowerera kwamadzi. Panthawi imodzimodziyo, imakhala ndi zomatira bwino, kuchepa kochepa komanso kusinthasintha m'mphepete mwa tile.

3. Kukonzanso matailosi ndi pulasitala matabwa:

Limbikitsani kumamatira ndi mphamvu yomangirira ya putty pazigawo zapadera (monga matailosi, zojambula, plywood ndi malo ena osalala), ndikuwonetsetsa kuti putty ili ndi kusinthasintha kwabwino kuti iwononge kukula kwa gawo lapansi.

4. Putty mkati ndi kunja kwa makoma:

Limbikitsani mphamvu yomangirira ya putty ndikuwonetsetsa kuti putty ili ndi kusinthasintha kwina kuti iteteze kukulitsa kosiyanasiyana ndi kupsinjika komwe kumapangidwa ndi zigawo zosiyanasiyana. Onetsetsani kuti putty ili ndi kukana kukalamba bwino, kusasunthika komanso kukana chinyezi.

5. Tondo wodziikira pansi:

Onetsetsani kuti mufanane ndi zotanuka modulus, kukana kupindika ndi kukana kwa matope. Limbikitsani kukana kuvala, mphamvu yomangirira ndi kulumikizana kwamatope.

6. Interface matope:

Sinthani mphamvu ya pamwamba pa gawo lapansi ndikuwonetsetsa kumamatira kwa matope.

7. Tondo lopanda madzi lopangidwa ndi simenti:

Onetsetsani kuti matope a matope akugwira ntchito yopanda madzi, ndipo nthawi yomweyo khalani ndi zomatira bwino pamtunda, ndikuwongolera mphamvu yopondereza komanso yosinthika yamatope.

Eight, kukonza matope:

Onetsetsani kuti coefficient yowonjezera ya matope ikugwirizana ndi zinthu zoyambira ndikuchepetsa zotanuka modulus matope. Onetsetsani kuti matope ali ndi madzi okwanira, kutulutsa mpweya komanso mphamvu yogwirizana.

9. Dongo la pulasitala la masonry:

Kupititsa patsogolo kusunga madzi.

Chepetsani kutaya madzi kukhala porous substrates.

Kupititsa patsogolo ntchito yomanga mosavuta ndikuwongolera magwiridwe antchito.
