I-Melamine urea-formaldehyde resin yimveliso ye-condensation ye-reaction phakathi kwe-formaldehyde, urea kunye ne-melamine. Ezi resin ziye zanda ukuchasana kwamanzi kunye nemozulu, okwenza ukuba zilungele ukuvelisa iipaneli zokusetyenziswa kwangaphandle okanye iimeko zokufuma okuphezulu. Ezi resins zibonelela ngokusebenza okuphezulu kwiipaneli, ezenza iindleko zabo zempahla ekrwada ziphezulu. Ezi resin zezona zincamathelisayo ezisetyenziswa ngokuqhelekileyo kwimveliso yezinto zokwakha.
Izicelo: I-Laminated veneer lumber (LVL), i-particleboard, i-medium density fiberboard (MDF), i-plywood.
I-Melamine urea-formaldehyde resins ifumaneka kwimixholo eyahlukeneyo ye-melamine ukuhlangabezana noluhlu olubanzi lweemfuno zabathengi, kwaye iimveliso zinokulungelelaniswa neemfuno zabathengi.
1. Ukwenziwa kwefenitshala yomthi: Urea-formaldehyde resin powder ingasetyenziselwa ukudibanisa iinkuni, iplywood, umgangatho weplanga kunye nenye ifanitshala yamaplanga. Inamandla okudibanisa okuphezulu kunye nokumelana nobushushu, kwaye inokubonelela ngefuthe elihlala ixesha elide.
2. Ishishini lePapermaking: I-Urea-formaldehyde resin powder ingasetyenziselwa njenge-agent yokuqinisa i-pulp yokwenza iphepha ukuze kuphuculwe amandla kunye nokuchasana kwamanzi kwephepha. Isenokwenza unxibelelwano oluluqilima phakathi kwemicu kwaye yandise amandla okuqina kunye nokuqina kwephepha.
3. Izinto ezibuyiswa ngumlilo: I-Urea-formaldehyde resin powder ingaxutywa kunye nezinye izinto ukuze zenze iingubo ezinqabileyo zomlilo kunye ne-flame retardant adhesives. Ezi zixhobo ezithintela amadangatye zisetyenziswa ngokubanzi kwizixhobo zombane, ukwakhiwa, kunye nokuthutha ukubonelela ngokhuseleko lomlilo.
4. Ishishini lokugquma: I-Urea-formaldehyde resin powder ingasetyenziselwa ukwenza iingubo ezinokumelana nokushisa okulungileyo kunye nokumelana nemozulu. Ezi zogquma zinokumelana okugqwesileyo komkrwelo kunye nokumelana neekhemikhali kwaye zisetyenziswa kakhulu kwiimoto, ulwakhiwo kunye namanye amasimi.
5. Ishishini lokwenziwa kwelaphu: I-Urea-formaldehyde resin powder nayo inezicelo ezininzi kwishishini lokwenziwa kwelaphu. Ingasetyenziselwa ukwenza izinto zokuncamathelisa ilaphu ezahlukeneyo, ezifana nesilika, amalaphu oboya, njl.njl. Ilaphu elidityaniswe ne-urea-formaldehyde resin powder linoxhathiso oluqinileyo lwamanzi kunye nokuqina, kwaye akulula ukucima kunye nokonakala. Ukongeza, i-urea-formaldehyde resin powder ingasetyenziselwa ukwenza iiarhente ezahlukeneyo zokuthintela amanzi, i-anti-wrinkle agents, njl.njl., ukwenza ilaphu libe lihle kwaye lisebenze.
6. I-Adhesive: I-Urea-formaldehyde resin powder ingasetyenziselwa njenge-adhesive jikelele yokudibanisa isinyithi, iglasi, i-ceramics kunye nezinye izinto. Inokuxhathisa okulungileyo kwamanzi kunye nokuchasana kweekhemikhali kwaye ifanelekile kwizicelo ezahlukeneyo zokubambisana kwamashishini.
Isishwankathelo, i-urea-formaldehyde resin powder yi-adhesive esemgangathweni ophezulu kunye nokuqina okuqinileyo kunye nokuchasana kwamanzi. Isetyenziswa ngokubanzi ekudibaneni kwezinto ezifana neenkuni, iimveliso zephepha, kunye namalaphu. Ukongeza, i-urea-formaldehyde resin powder ingasetyenziselwa ukwenza izinto ezixubileyo, izinto zokugquma, ii-anti-corrosion coatings, njl., kwaye inoluhlu olubanzi lokusetyenziswa kunye nethemba lokusetyenziswa.
