I-Pvang Pewder yePva powder: Amanyathelo ama-3 okwenza isisombululo se-PPA kwizicelo eziguquguqukayo

I-Polyvinyl Acetate (PVA) iPOLDER yi-polymer eguquguqukayo enokuthi ichithwe emanzini ukwenza isicombululo ngezicelo ezahlukeneyo, kubandakanya imibhedu, iingubo, kunye ne-emulssions. Nanga amanyathelo amathathu okwenza isisombululo se-PPA kwizicelo eziguquguqukayo:

1. Ukulungiswa kwesisombululo se-PVA:
   • Linganisa inani elifunekayo lomgubo wePva usebenzisa isikali. Imali iya kwahluka ngokuxhomekeke kwi-ofisi enqwenelekayo yesisombululo kunye nesicelo esithile.
   • Ngokuthe ngcembe yongeza i-Pva edikiweyo yamanzi amanzi amachiza okanye ama-deofer kwisitya esicocekileyo. Kubalulekile ukusebenzisa amanzi asemgangathweni aphezulu ukuthintela ukungcola ekuchaphazeleni iipropathi zesisombululo.
   • Hambisa umxube ngokuqhubekayo usebenzisa umxube woomatshini okanye i-rod eshukumisayo ukuqinisekisa ukusasazeka kwe-Pva powder emanzini.
   • Qhubeka nokuvuselela de i-Pva powder ichithwe ngokupheleleyo emanzini kwaye akukho zidumbulo okanye amasuntswana ahlala. Le nkqubo inokuthatha ixesha, kuxhomekeka kuxinzelelo lwesisombululo kunye nobushushu bamanzi.
2. Ulawulo lobushushu:
   • Ukufudumeza amanzi kunokukhawulezisa inkqubo yokuchitheka kunye nokuphucula ukunyibilikisi kwePva powder. Nangona kunjalo, kubalulekile ukuphepha ubushushu obugqithisileyo, njengoko unokuyithoba i-polymer kwaye ichaphazele iipropathi zesisombululo.
   • Gcina iqondo lobushushu ngaphakathi koluhlu olufanelekileyo ngokusekwe kwinqanaba elithile lePvapler esetyenzisiweyo. Ngokubanzi, amaqondo obushushu aphakathi kwe-50 ° C ukuya kuma-70 ° C akwanele ukunyibilikisa uninzi lwePUALDS.
3. Ukulawulwa komgangatho kunye novavanyo:
   • Emva kokulungiselela isisombululo se-PVA, yenza iimvavanyo zolawulo olusemgangathweni ukuqinisekisa ukuba ifezekisa imigaqo oyifunayo kunye neemfuno zomsebenzi wentsebenzo zesicelo esicetywayo.
   • Vavanya i-viscofity, i-PH, imixholo ye-solid, kunye nezinye iipropathi ezifanelekileyo zesisombululo sePCA usebenzisa iindlela ezifanelekileyo zokuvavanywa kunye nezixhobo.
   • Lungisa indlela okanye ukuqhutywa kweeparameters njengoko kufuneka ukuze kuqinisekiswe iipropathi zesisombululo sePDA yezicelo ezithile.

Ngokulandela la manyathelo kwaye unikele ingqalelo kulawulo lobushushu kunye namanyathelo olawulo olukumgangatho, unokulungiselela ngempumelelo isisombululo sePCA silungele uluhlu olubanzi lwezicelo ezahlukeneyo. Kubalulekile ukugcina isisombululo ngokufanelekileyo kwisikhongozelo esicocekileyo, esitywiniweyo sokuthintela ungcoliseko kwaye ugcine uzinzo ngokuhamba kwexesha. Ukongeza, nxibelelana namaphepha edatha yezobuchwepheshe kunye nezikhokelo ezibonelelwe ngumenzi weengcebiso ezithile malunga nokulungiselela izisombululo zePDA yezicelo ezahlukeneyo.
