1. Isishwankathelo se-urea-formaldehyde resin (UF)
I-urea-formaldehyde resin, ebizwa ngokuba yi-UF, isetyenziswa kakhulu ekuhlanganiseni imithi kwaye ikhuthaze ukusetyenziswa okukhulu kwimveliso yeplywood kunye ne-particleboard.
2. Iimpawu
I-urea-formaldehyde resin ithandwa kakhulu ngenxa yezinto zayo ezininzi ezikrwada kunye nexabiso layo eliphantsi. Inamathela kakuhle, imelana nee-asidi ezibuthathaka kunye ne-alkalis ezibuthathaka, kwaye ibonakalisa ukugquma okuhle kunye nokumelana nokuguguleka. Nangona kunjalo, kubalulekile ukuqaphela ukuba i-formaldehyde ikhutshwa ngexesha lenkqubo yayo yokunyanga, kwaye ukumelana kwayo nobushushu kunye nokumelana nokwaluphala kubuthathaka kakhulu.
3. Ifomu
I-urea-formaldehyde resiningaboniswa ngeendlela ezahlukeneyo ezifana ne-resin, i-powder, ibhodi kunye ne-adhesive ukuhlangabezana neemfuno ezahlukeneyo zokusetyenziswa.
4. Iinkqubo ezisebenzayo
I-urea-formaldehyde resin ifanelekile kwiinkqubo ezahlukeneyo ezifana nokugquma kunye nokubumba okucinezelweyo, inika inkxaso ekwenzeni iimveliso ezahlukeneyo.
5. Isicelo
Njengeyona glue isetyenziswa kakhulu kwishishini lokucubungula iinkuni,i-urea-formaldehyde resinIsetyenziswa kakhulu ekudibaniseni imithi, iplywood, iilaminates, kunye neemveliso zebamboo kunye neenkuni. Umzekelo, isetyenziselwa ukwenza amaqokobhe enkuni ngeemigangatho, ifenitshala, iibhokisi zokupakisha, izixhobo zelaphu, kunye nezixhobo zasekhaya.
1. Ukuphucula ukumelana kwamanzi kwe-urea-formaldehyde resin adhesive: Ngokongeza ii-agents ezidibanisayo ezifana ne-aluminium sulfate kunye ne-aluminium phosphate, ukumelana kwayo namanzi kunokuphuculwa ngempumelelo.
2. Ukuphucula ukumelana nokwaluphala: Ukuxuba ezinye iiresini ze-thermoplastic kwiisisitheliso ze-urea-formaldehyde resin kunokuphucula kakhulu ukumelana kwazo nokwaluphala.
3. Nciphisa umxholo we-formaldehyde: Ngokulungisa inkqubo yokwenziwa, ukunciphisa umlinganiselo we-molar we-formaldehyde kwi-urea, okanye ukongeza izinto ezisusa i-formaldehyde (ezifana ne-urea, i-melamine, njl.njl.), injongo yokunciphisa umxholo we-formaldehyde kwi-urea-formaldehyde resin adhesives inokufezekiswa.
I-Aojin Chemical ithengisa ii-urea-formaldehyde resins ezikumgangatho ophezulu ezinemigangatho ephezulu yemveliso. Nika imboni yefenitshala kunye nemboni yebhodi. Fumana ixabiso elihle le-urea-formaldehyde resin ngoku, nxibelelana ne-Aojin Chemical ngokukhawuleza!
