Inhloso yokusungulwa kwamanje ukuhlinzeka ngendlela yokuthuthukisa ukusebenza kokucubungula nempilo yomkhiqizo wei-melamine powder yokubumbaimikhiqizo, ukonga izinsiza, ukwandisa umbala wemikhiqizo ebunjiwe, nokwenza ngcono ukuhlukahluka kwemikhiqizo ebunjiwe.
Indlela yokulungiselela ihlanganisa ukulungiselelwa kwengxenye ye-A, ukulungiswa kwengxenye engu-B kanye nokulungiswa komkhiqizo ophelile.
Izinyathelo zokulungiselela ingxenye
1. Ukusabela: Ku-reactor, i-formaldehyde resin yenziwa isixazululo se-formaldehyde esingu-38% ngokwesilinganiso, futhi inani le-pH lilungiswa libe ngu-8.5 ku-reactor, bese i-melamine yengezwa ngesilinganiso sokusabela.Ukushisa ku-90 ° C kuze kube sekupheleni;
2. Ukuxova: Ngemva kokupholisa ku-70°C, faka into esabelayo ku-kneader, bese wengeza i-wood pulp fiber kanye ne-pigment A ngokwesilinganiso sokuxova.
3. Ukomisa: Ngemva kokuxova, faka kuhhavini ukuze zomiswe.Ihhavini yamukela i-oven ye-mesh yebhande lomoya oshisayo, omiswe emoyeni oshisayo ku-85 ° C, futhi umswakama ulawulwa ngaphansi kuka-3.5% ukuze uthole izinto ezomile.
4. Ukugaya ibhola: thumela izinto ezomisiwe endaweni yokugaya ibhola, engeza okokugcoba, i-ejenti yokwelapha, i-titanium dioxide kanye nezithako ze-pigment A ngokulingana, futhi uqedele ukuminyana nokumataniswa kombala ngokugaya ibhola emahoreni ayi-9;
Izinyathelo zokulungiselela zengxenye B
Umbala wengxenye B uhlukile engxenyeni A, kodwa izinyathelo zokulungiselela ziyafana.
Ukulungiswa komkhiqizo okuqedile: hlanganisa ngokulinganayo ingxenye A kanye nengxenye Bi-melamine powders, bese uwafaka esikhwameni sephepha esifakwe ifilimu.Impushana eqediwe kufanele igcinwe endaweni engaphansi kuka-25°C.
