Okuqukethwe komlotha kusuka kokujwayelekilei-polymer powder ehlakazeka kabushaimboni ivamise ukuba ngu-10±2
Izinga lokuqukethwe komlotha lingaphakathi kuka-12%, futhi ikhwalithi nentengo kuyaqhathaniswa
Ezinye izimpushana ze-latex zasekhaya zingaphezu kuka-30%, kanti ezinye izimpushana zerabha zinomlotha ofinyelela ku-50%.
Manje ikhwalithi kanye nentengo ye-polymer powder ehlakazekayo emakethe ayilingani, zama ukukhetha
Okuqukethwe komlotha ophansi, ukusebenza kwezindleko eziphezulu kanye nekhwalithi ezinzile yokuhlinzeka.
Ungayikhetha kanjani impushana ye-latex ehlakazeka kabusha, ngokuvamile akunakwenzeka ngempela ukuqala lapho wenza ifomula,
Ayikho indlela esebenzayo ngaphandle kokuyibeka emkhiqizweni ukuze ihlolwe.
Ukukhethwa kwempushana ye-polymer ehlakazekayo efanelekile kufanele kubhekwe kulezi zici ezilandelayo:
1. Izinga lokushisa lengilazi lokuguquka kwempushana ye-polymer ehlakazekayo.
Izinga lokushisa lokushintsha kwengilazi yi-polymer ekhombisa ukunwebeka;ngaphansi kwalokhu kushisa, i-polymer ibonisa ukuqina.
Ngokuvamile, izinga lokushisa lokushintsha kwengilazi le-latex powder lingu-15±5℃.
Ngokuyisisekelo ayikho inkinga.
Izinga lokushisa lokushintsha kwengilazi liyinkomba enkulu yezinto ezibonakalayo ze-polymer powders ezihlakazekayo, kanye nemikhiqizo ethile,
Ukukhetha okunengqondo kwezinga lokushisa lokushintsha kwengilazi kwempushana ye-polymer ehlakazekayo kusiza ekuthuthukiseni ukuguquguquka komkhiqizo nokugwema.
ukuqhekeka, njll.
2. Izinga lokushisa elincane lokwakha ifilimu
Ngemuva kokuthi i-polymer powder e-redispersible ne-redispersible ihlanganiswe namanzi futhi ifakwe kabusha, inezici ezifanayo ne-emulsion yasekuqaleni.
Okusho ukuthi, ngemva kokuba amanzi eqhuma, kuzokwakhiwa ifilimu, enokuguquguquka okuphezulu nokunamathela okuhle kuma-substrates ahlukahlukene.
Izinga lokushisa elincane lokubumba ifilimu le-latex powder elikhiqizwa abakhiqizi abahlukene lizohluka kancane.
Inkomba yabanye abakhiqizi ingu-5 ℃, inqobo nje uma impushana ye-latex enekhwalithi enhle inezinga lokushisa elenza ifilimu eliphakathi kuka-0 no-5 ℃.
3. Izakhiwo ezincibilika kabusha.
Izimpushana ze-polymer ezihlakazekayo ezingaphansi zincibilika kancane noma azincibiliki kalula emanzini abandayo noma emanzini ane-alkaline.
4. Inani.
Okuqukethwe okuqinile kwe-emulsion cishe ku-53%, okusho ukuthi cishe amathani angu-1.9 we-emulsion aqina ibe ithani elilodwa le-rubber powder.
Uma ubala u-2% wamanzi, lokho kungamathani angu-1.7 we-emulsion ukwenza ithani elilodwa lempushana yerabha, kanye no-10% womlotha,
Kuthatha cishe amathani angu-1.5 we-emulsion ukukhiqiza ithani elilodwa lempushana yerabha.5. Isixazululo esinamanzi se-latex powder
Ukuze uhlole i-viscosity ye-latex powder ehlakazeka kabusha, amanye amakhasimende avele ancibilikise impushana ye-latex
Ngemva kokuyinyakazisa amanzi, ngayihlola ngesandla, ngathola ukuthi yayinganamatheli, ngakho ngacabanga ukuthi kwakungeyona impushana ye-latex yangempela.
Eqinisweni, i-latex powder ephinda ihlakazeka ngokwayo ayinamathele, yakhiwa ngokumiswa kokufuthwa kwe-polymer emulsion.kwempushana.
Lapho i-polymer powder ehlakazeka kabusha ixubene namanzi futhi ifakwe kabusha, inezici ezifanayo njenge-emulsion yasekuqaleni, okungukuthi, umswakama.
Amafilimu akhiwe ngemva kokuhwamuka ayashintshashintsha kakhulu futhi anamathela kahle kakhulu kuma-substrates ahlukahlukene.
Kungase futhi kuthuthukise ukugcinwa kwamanzi kwento futhi kuvimbele udaka lukasimende ukuthi luqine, lome futhi luqhekeke ngokushesha;
Khulisa ipulasitiki yodaka futhi uthuthukise ukusebenza kahle kokwakhiwa.Uma ukuhlolwa kuzokwenziwa, kufanele kulingane
Yenza ukuhlolwa kabusha kodaka ukuze ubone ukuhlakazeka kwayo, ukwakheka kwefilimu, ukuguquguquka (kuhlanganise nokuhlolwa kokukhipha,
Ukuthi amandla okuqala afanelekile) Ngokuvamile, imiphumela yokuhlola ingatholwa ngemva kwezinsuku eziyi-10
