I-Melamine urea-formaldehyde resin yimveliso yokuxinana kwe-reaction phakathi kwe-formaldehyde, i-urea kunye ne-melamine. Ezi resin zinokumelana kwamanzi kunye nemozulu okwandileyo, nto leyo eyenza ukuba zilungele ukuvelisa iipaneli zokusetyenziswa ngaphandle okanye kwiimeko zokufuma okuphezulu. Ezi resin zibonelela ngokusebenza okuphezulu kwiipaneli, nto leyo ehlawulela iindleko zazo eziphezulu zezinto ezikrwada. Ezi resin zezona zincamathelisi zisetyenziswa kakhulu kwimveliso yezinto zokwakha.
Izicelo: I-laminated veneer lumber (LVL), i-particleboard, i-medium density fiberboard (MDF), i-plywood.
Iiresini ze-melamine urea-formaldehyde ziyafumaneka kwi-melamine ezahlukeneyo ukuze zihlangabezane neemfuno zabathengi ezahlukeneyo, kwaye iimveliso zinokulungiswa ngokweemfuno zabathengi.
1. Ukwenziwa kwefenitshala yomthi: Umgubo we-resin we-Urea-formaldehyde ungasetyenziselwa ukubopha iinkuni, i-plywood, umgangatho womthi kunye nezinye iifenitshala zomthi. Unamandla aphezulu okubopha kunye nokumelana nobushushu, kwaye unokubonelela ngesiphumo sokubopha esihlala ixesha elide.
2. Ishishini lokwenza iphepha: Umgubo we-resin we-urea-formaldehyde ungasetyenziswa njengesixhobo sokuqinisa i-pulp yokwenza iphepha ukuphucula amandla kunye nokumelana namanzi ephepha. Unokwenza unxibelelwano oluqinileyo phakathi kweefayibha kwaye wonyuse amandla okuxinana kunye nokuqina kwephepha.
3. Izinto ezithintela ilangatye: Umgubo we-resin we-Urea-formaldehyde ungaxutywa nezinye izinto ukwenza iingubo ezithintela ilangatye kunye nezincamathelisi ezithintela ilangatye. Ezi zinto ezithintela ilangatye zisetyenziswa kakhulu kwizixhobo zombane, ulwakhiwo, kunye nothutho ukubonelela ngokhuseleko lomlilo.
4. Ishishini lokugquma: Umgubo we-resin we-urea-formaldehyde ungasetyenziselwa ukwenza iingubo ezinokumelana kakuhle nobushushu kunye nokumelana nemozulu. Ezi ngubo zinokumelana okuhle nokukrwela kunye nokumelana neekhemikhali kwaye zisetyenziswa kakhulu kwiimoto, ulwakhiwo nakwezinye iindawo.
5. Ishishini lokuvelisa amalaphu: Umgubo we-resin we-Urea-formaldehyde nawo usetyenziswa kakhulu kwishishini lokuvelisa amalaphu. Ungasetyenziselwa ukwenza izinto ezahlukeneyo zokuncamathelisa amalaphu, njengesilika, amalaphu oboya, njl. Ilaphu elidityaniswe nomgubo we-resin we-urea-formaldehyde linokumelana kakhulu namanzi kwaye lihlala ixesha elide, kwaye akulula ukulifiphalisa nokulitshintsha. Ukongeza, umgubo we-resin we-urea-formaldehyde ungasetyenziselwa ukwenza izinto ezahlukeneyo zokuthintela ukungenwa kwamanzi amalaphu, izinto ezilwa nemibimbi, njl., nto leyo eyenza ilaphu libe lihle kwaye lisebenziseke ngakumbi.
6. I-Adhesive: Umgubo we-resin we-Urea-formaldehyde ungasetyenziswa njengesincamathelisi esiqhelekileyo kwisinyithi esinamathelisisiweyo, iglasi, i-ceramics kunye nezinye izinto. Unokumelana kakuhle kwamanzi kunye nokumelana neekhemikhali kwaye ufanelekile kwiintlobo ngeentlobo zezicelo zokubopha kwimizi-mveliso.
Ngamafutshane, umgubo we-urea-formaldehyde resin sisincamathelisi esisemgangathweni ophezulu esihlala ixesha elide kwaye simelana namanzi. Sisetyenziswa kakhulu ekudibaniseni izinto ezifana nomthi, iimveliso zephepha, kunye namalaphu. Ukongeza, umgubo we-urea-formaldehyde resin ungasetyenziselwa ukwenza izinto ezirhabaxa, izinto zokukhusela, izinto zokugquma, njl.njl., kwaye unoluhlu olubanzi lokusetyenziswa kunye namathuba okusetyenziswa.
