1. Ukubuka konke kwe-urea-formaldehyde resin (UF)
I-resin ye-urea-formaldehyde, ebizwa ngokuthi i-UF, ivame ukusetshenziswa ekuhlanganiseni izinkuni futhi ikhuthaze ukusetshenziswa okukhulu ekukhiqizweni kwe-plywood kanye ne-particleboard.
2. Izici
I-resin ye-urea-formaldehyde ithandwa kakhulu ngenxa yezinto zayo eziningi zokusetshenziswa kanye nentengo ephansi. Inamathela kahle kakhulu, imelana nama-acid abuthakathaka kanye nama-alkali abuthakathaka, futhi ikhombisa ukuvikela okuhle kanye nokumelana nokuguguleka. Kodwa-ke, kubalulekile ukuqaphela ukuthi i-formaldehyde ikhishwa ngesikhathi senqubo yayo yokupholisa, futhi ukumelana kwayo nokushisa kanye nokumelana nokuguga kubuthakathaka kakhulu.
3. Ifomu
I-resin ye-Urea-formaldehydeingalethwa ngezindlela ezahlukene njenge-resin, i-powder, ibhodi kanye ne-glue ukuze kuhlangatshezwane nezidingo ezahlukene zokusetshenziswa.
4. Izinqubo ezisebenzayo
I-resin ye-urea-formaldehyde ifanelekela izinqubo ezahlukahlukene ezifana nokumboza kanye nokubumba okucindezelwe, okunikeza ukwesekwa kokwenziwa kwemikhiqizo ehlukahlukene.
5. Isicelo
Njengeglue esetshenziswa kakhulu embonini yokucubungula izinkuni,i-urea-formaldehyde resinisetshenziswa kabanzi ekuhlanganiseni izinkuni, i-plywood, ama-laminate, kanye nemikhiqizo yoqalo kanye neyokhuni. Isibonelo, isetshenziselwa ukwenza amagobolondo ezinkuni phansi, ifenisha, amabhokisi okupakisha, imishini yendwangu, kanye nezinto zasekhaya.
1. Thuthukisa ukumelana kwamanzi kwe-urea-formaldehyde resin glue: Ngokufaka ama-cross-linking agents njenge-aluminium sulfate kanye ne-aluminium phosphate, ukumelana kwayo namanzi kungathuthukiswa ngempumelelo.
2. Thuthukisa ukumelana nokuguga: Ukuxuba amanye ama-resin e-thermoplastic kuma-resin anamathelayo e-urea-formaldehyde kungathuthukisa kakhulu ukumelana kwawo nokuguga.
3. Nciphisa okuqukethwe kwe-formaldehyde: Ngokulungisa inqubo yokwenziwa, ukunciphisa isilinganiso se-molar se-formaldehyde ku-urea, noma ukwengeza izinto zokukhipha i-formaldehyde (njenge-urea, i-melamine, njll.), inhloso yokunciphisa okuqukethwe kwe-formaldehyde kuma-resin anamathelayo e-urea-formaldehyde ingafezwa.
I-Aojin Chemical ithengisa ama-resin e-urea-formaldehyde asezingeni eliphezulu anezindinganiso zekhwalithi ephezulu yomkhiqizo. Nikeza embonini yefenisha kanye nasembonini yamabhodi. Thola intengo engcono kakhulu ye-urea-formaldehyde resin manje, xhumana ne-Aojin Chemical ngokushesha!
