Injongo yokuqanjwa kwangoku kukubonelela ngendlela yokuphucula ukusebenza kokulungiswa kunye nobomi bemvelisoi-melamine powder yokubumbaiimveliso, ukugcina izixhobo, ukwandisa umbala weemveliso ezibunjiweyo, kunye nokuphucula ukuhlukahluka kweemveliso ezibunjiweyo.
Indlela yokulungiselela ibandakanya ukulungiswa kwecandelo, ukulungiswa kwecandelo B kunye nokulungiswa kwemveliso egqityiweyo.
Amanyathelo okulungiselela icandelo
1. Ukuphendula: Kwi-reactor, i-resin ye-formaldehyde yenziwe kwi-38% yesisombululo se-formaldehyde ngokulinganayo, kwaye ixabiso le-pH lilungelelaniswe kwi-8.5 kwi-reactor, kwaye i-melamine yongezwa ngokulingana nokusabela.Ukushisa kwi-90 ° C ukuya kwindawo yokugqibela;
2. Ukuxova: Emva kokupholisa kwi-70 ° C, faka i-reactant kwi-kneader, kwaye ungeze i-fiber pulp yomthi kunye ne-pigment A ngokomlinganiselo wokuxova.
3. Ukomisa: Emva kokuxova, faka i-oven ukuze yomiswe.I-oven ithatha i-oven ye-mesh yebhanti yomoya oshushu, omiswe emoyeni oshushu kwi-85 ° C, kwaye umswakama ulawulwa ngaphantsi kwe-3.5% ukufumana izinto ezomileyo.
4. Ukugaya ibhola: thumela izinto ezomileyo kwibhola lebhola, yongeza i-lubricant, i-ejenti yokunyanga, i-titanium dioxide kunye ne-pigment A additives ngomlinganiselo, kwaye ugqibezele ukuxinana kunye nokudibanisa umbala ngebhola kwiiyure ezili-9;
Amanyathelo okulungiselela ecandelo B
Umbala wecandelo B uhlukile kwicandelo A, kodwa amanyathelo okulungiselela afana.
Ukulungiswa kwemveliso egqityiweyo: ukuxuba ngokulinganayo icandelo A kunye necandelo Bmelamine powders, uze uwapakishe kwisikhwama sephepha esinefilimu.Umgubo ogqityiweyo kufuneka ugcinwe kwindawo engaphantsi kwama-25 ° C.
