1. Uhlolojikelele lwe-urea-formaldehyde resin (UF)
I-Urea-formaldehyde resin, ebizwa ngokuthi i-UF, ijwayele ukusetshenziselwa ukuhlanganisa izinkuni futhi ikhuthaze ukusetshenziswa okukhulu ekukhiqizeni i-plywood kanye ne-particleboard.
2. Izici
I-Urea-formaldehyde resin ithandwa ngenxa yezinto zayo ezingavuthiwe eziningi kanye nenani eliphansi. Inonamathela okuhle kakhulu, imelana nama-asidi abuthakathaka nama-alkali abuthakathaka, futhi ikhombisa ukwahlukanisa okuhle nokumelana nokugqoka. Kodwa-ke, kufanelekile ukuqaphela ukuthi i-formaldehyde ikhishwa ngesikhathi senqubo yokwelapha, futhi ukumelana nokushisa kwayo nokumelana nokuguga kubuthakathaka.
3. Ifomu
Urea-formaldehyde resinzingase zethulwe ngezindlela ezihlukahlukene ezifana ne-resin, impushana, ibhodi kanye ne-adhesive ukuhlangabezana nezidingo ezahlukene zokufaka isicelo.
4. Izinqubo ezisebenzayo
I-resin ye-Urea-formaldehyde ifaneleka ezinqubweni ezihlukahlukene ezifana nokuhlanganisa nokubunjwa kokucindezela, okuhlinzeka ngokusekela ukwakhiwa kwemikhiqizo ehlukahlukene.
5. Isicelo
Njengeglue esetshenziswa kakhulu embonini yokucubungula izinkuni,i-urea-formaldehyde resinisetshenziswa kabanzi ekuhlanganiseni izinkuni, i-plywood, laminates, kanye nemikhiqizo yoqalo kanye nezinkuni. Ngokwesibonelo, isetshenziselwa ukwenza amagobolondo okhuni ephansi, ifenisha, amabhokisi okupakisha, izinto zendwangu, nezinto zikagesi zasendlini.
1. Thuthukisa ukumelana kwamanzi kwe-urea-formaldehyde resin adhesive: Ngokungeza ama-agent axhumanisa ama-cross-link njenge-aluminium sulfate ne-aluminium phosphate, ukumelana kwawo kwamanzi kungathuthukiswa ngokuphumelelayo.
2. Thuthukisa ukumelana nokuguga: Ukuxuba ezinye izinhlaka ze-thermoplastic zibe izinto ezinamathelayo ze-urea-formaldehyde resin kungathuthukisa kakhulu ukumelana kwazo nokuguga.
3. Yehlisa okuqukethwe kwe-formaldehyde: Ngokulungisa inqubo yokuhlanganisa, ukunciphisa isilinganiso se-molar ye-formaldehyde ku-urea, noma ukwengeza ama-scavengers e-formaldehyde (njenge-urea, i-melamine, njll.), inhloso yokunciphisa okuqukethwe kwe-formaldehyde ku-urea-formaldehyde resin adhesives ingafinyelelwa.
I-Aojin Chemical ithengisa izinhlaka ze-urea-formaldehyde zekhwalithi ephezulu ezinamazinga aphezulu ekhwalithi yomkhiqizo. Ukuhlinzekwa kwemboni yefenisha kanye nemboni yebhodi. Thola intengo engcono kakhulu ye-urea-formaldehyde resin manje, xhumana ne-Aojin Chemical ngokushesha!
