1. Isishwankathelo se-urea-formaldehyde resin (UF)
I-resin ye-Urea-formaldehyde, ebizwa ngokuba yi-UF, isetyenziswa ngokuqhelekileyo kwi-bonding yomthi kwaye ikhuthaze izicelo ezinkulu ekuveliseni i-plywood kunye ne-particleboard.
2. Iimpawu
I-resin ye-Urea-formaldehyde ithandwa ngenxa yezinto zayo ezininzi eziluhlaza kunye nexabiso eliphantsi. Inoncanyathiso olugqwesileyo, iyamelana neeasidi ezibuthathaka kunye neealkali ezibuthathaka, kwaye ibonisa ukugquma okulungileyo kunye nokumelana nokunxiba. Nangona kunjalo, kuyafaneleka ukuba uqaphele ukuba i-formaldehyde ikhutshwa ngexesha lokunyanga kwayo, kwaye ukumelana nokushisa kwayo kunye nokuguga akunamandla.
3. Ifomu
Urea-formaldehyde resininokubonakaliswa ngeendlela ezahlukeneyo ezifana nentlaka, umgubo, ibhodi kunye nokuncamathelisa ukuhlangabezana neemfuno ezahlukeneyo zesicelo.
4. Iinkqubo ezisebenzayo
I-resin ye-Urea-formaldehyde ifanelekile kwiinkqubo ezahlukeneyo ezifana nokugubungela kunye nokunyanzeliswa koxinzelelo, ukubonelela ngenkxaso yokwenziwa kweemveliso ezahlukeneyo.
5. Isicelo
Njengeyona glu isetyenziswa kakhulu kwishishini lokulungisa iinkuni,urea-formaldehyde resinisetyenziswa kakhulu ekudibaneni komthi, iplywood, i-laminates, kunye ne-bamboo kunye neemveliso zomthi. Ngokomzekelo, isetyenziselwa ukwenza amaqokobhe amaplanga emigangatho, ifanitshala, iibhokisi zokupakisha, izixhobo zamalaphu kunye nezixhobo zendlu.
1. Ukuphucula ukuxhathisa kwamanzi kwi-urea-formaldehyde resin adhesive: Ngokongeza i-agent edibanisa i-cross-link njenge-aluminium sulfate kunye ne-aluminium phosphate, ukuxhathisa kwamanzi kunokuphucula ngokufanelekileyo.
2. Ukuphucula ukuxhathisa ukwaluphala: Ukuxuba ezinye iintlaka ze-thermoplastic kwi-urea-formaldehyde resin adhesives kunokuphucula kakhulu ukuxhathisa ukuguga.
3. Ukunciphisa umxholo we-formaldehyde: Ngokulungelelanisa inkqubo ye-synthesis, ukunciphisa umlinganiselo we-molar we-formaldehyde kwi-urea, okanye ukongeza i-formaldehyde scavengers (njenge-urea, i-melamine, njl.), injongo yokunciphisa umxholo we-formaldehyde kwi-urea-formaldehyde resin adhesives inokufezekiswa.
I-Aojin Chemical ithengisa umgangatho ophezulu we-urea-formaldehyde resins kunye nemigangatho ephezulu yemveliso. Ukubonelela kwishishini lefenitshala kunye neshishini lebhodi. Fumana elona xabiso lihle le-urea-formaldehyde resin ngoku, qhagamshelana ne-Aojin Chemical ngokukhawuleza!
