Ungayisebenzisa kanjani i-polymerverible polymer powder?

I-Redisperible Powmer Powder (RDP) isengezo sezinto ezibalulekile zokwakha, ezisetshenziswa ikakhulukazi ezintweni zokwakha ezokwakha i-powder, njengodaka olomile, i-putty adhesive, ukumelana, ukumelana, ukumelana, ukumelana nokuqhekeka kwamanzi okuqukethwe, futhi kusetshenziswa kabanzi ekwakhiweni kwamanzi.

1. Ukukhethwa kwezinto ezibonakalayo

Ngaphambi kokusebenzisa i-polymer powder evuselelayo, okokuqala udinga ukukhetha izinhlobonhlobo ezifanele. Khetha izinhlobo ezahlukene ze-latex powder ngokuya ngezidingo ezithile zokwakhiwa. Ngokwesibonelo:

I-PolyethYlene Vinyl Acetate Copolymer (EVA): isetshenziswa kabanzi ku-tile anamathela, udaka ngodaka, njll., Ngokunamathela okuhle nokuvumelana nezimo.

I-Ethylene-acrylic acid Copolymer (VAE): Isetshenziswa kakhulu ku-Floor Gotar kanye nohlelo lokufakelwa ukuze uthuthukise ukumelana nokuvimbela.

I-acrylic copolymer: isetshenziswa ezindaweni ezinamandla amakhulu, njengodaka lwangaphandle oludongeni oludongeni, ngokumelana kahle kwamanzi nokumelana nesimo sezulu.

2. Design formula

Lapho usebenzisa i-polymer powder evuselelekayo, ifomula idinga ukulungiswa ngokuya ngezidingo zephrojekthi. Ngokuvamile, inani le-latex powder elingeziwe liphakathi kuka-2% no-5% wesisindo esiphelele sikasimende usimende, ngokuya ngezidingo zomkhiqizo. Izinyathelo ezithile zinjengokulandelayo:

Ukulungiselela ukuhlanganiswa okulomile: hlanganisa usimende, i-aggregate enhle (enjenge-quartz sand), i-filler (enjenge-calcium esindayo) nezinye izikhala ezomile ngokuya ngesilinganiso sefomula.

Ukungeza i-polymer polymer evuselelayo

Ukungeza i-cellulose ether: Ukuze kuthuthukiswe ukugcinwa kwamanzi kanye nokwenza umsebenzi womonga wodaka, inani elithile le-cellulose ether (efana ne-hydroxypropyllylylylylylylylylylylylllose) kuvame ukungezwa kwifomula.

3. Ukulungiselela ukwakhiwa

Ngaphambi kokwakha, qiniseka ukuthi zonke izinto ezingavuthiwe namathuluzi akulungele, futhi axube i-powder eyomile ngokusho kwefomula. Ngesikhathi senqubo yokwakha, i-polymer powder evuselelayo ihlelwe kabusha ngemuva kokuxhumana namanzi ukwakha ifilimu elizinzile le-polymer, ngaleyo ndlela lenze ukumelana nokumelana kwamanzi ngodaka.

Ukuxuba: Faka inani elifanele lamanzi ku-powder eyomile elungiselelwe, futhi uvuse ngokulinganayo nge-mechanical stitter kuze kukhiqizwe umfaniswano, kumiswa umfaniswano we-lump-free. Isikhathi sokuvuselela ngokuvamile imizuzu emi-3-5 ukuqinisekisa ukuthi wonke ama-powders amanzi ngokuphelele.

Ukuma nokuvuthwa: Ngemuva kokuvusa, ama-slurry kufanele ashiywe imizuzu embalwa ukuze avuthwe ngokuphelele ukwenza ngcono ukusebenza kokwakha. Bese uyivuselela kancane futhi ngaphambi kokusebenzisa.

4. Indlela yesicelo

Faka isicelo se-slurry exubekile ekwakheni kokwakha ngokuya ngezidingo ezithile zokwakhiwa. Izindlela ezijwayelekile zohlelo lokusebenza zifaka:

Udaka oluphambanisa

I-Tile Adhesive: Sebenzisa i-scracer efakwe ngamazinyo ukuze usebenzise ukuthambekela kwethayela endaweni eyisisekelo, bese ucindezela i-tile kwisendlalelo esinamathela.

Udaka lokuzimela: uthele udaka oludidiyele olusezingeni eliphansi emhlabathini bese usebenzisa izakhiwo zalo zokuzikhandla ukwakha ungqimba olufulethi.

5. Ukuqapha

Lapho usebenzisa i-polymer polymer powder, naka amaphuzu alandelayo:

Izimo zemvelo Amazinga okushisa ajwayelekile wokwakha kufanele abe phakathi kuka-5°C no-35°C.

Ukuxuba Amanzi: Sebenzisa amanzi ahlanzekile, angavikelekile ngokuxuba ukugwema izinkinga zekhwalithi yamanzi ezithinta ukusebenza kodaka.

Imibandela yokugcina: I-polymer engasetshenziswanga i-polymerble powder kufanele igcinwe endaweni eyomile, epholile ukugwema umswakama kanye nokushisa okuphezulu.

Ukulungiswa Kwezilinganiso: Ngokwesimo sangempela, kalula ukulungisa inani le-polymer powder evuselelwayo engezwe ukufeza umphumela omuhle kakhulu wokwakha.

6. Ukuhlolwa kokusebenza nokulungiswa

Ngemuva kokuqedwa kokwakha, udaka oluqediwe kufanele luhlolwe ukusebenza, njengamandla ezibopho, amandla acindezelayo, ukumelana kwamanzi, njll., Ukuqinisekisa ukuthi ihlangabezana nezidingo zobunjiniyela. Ngasikhathi sinye, ingaphezulu ngemuva kokwakhiwa kufanele ligcinwe njengoba kunesidingo, ikakhulukazi ekushiseni okuphezulu noma endaweni eyomile, ukuvikela ukulahleka kwamanzi kusenesikhathi.

Njengesengezo sokwakha esibalulekile, i-polymer powder evuselelayo idlala indima ebalulekile ekwenzeni ngcono ukunamathela, ukuguquguquka nokuqina kodaka. Ukukhetha okulungile nokusetshenziswa kwe-polymer powder evuselelayo akukwazi ukwenza ngcono kuphela ikhwalithi yokwakha, kepha futhi kunwebe nempilo yenkonzo yesakhiwo. Esimweni sangempela, abasebenzi bezokwakha kufanele balandele ngokuqinile ukwakheka kwefomula kanye nezidingo zokwakha ukuqinisekisa ukuqina kanye nokwethenjwa kwekhwalithi yobunjiniyela.
