Melamine resin ndi polima yomwe imapezeka chifukwa cha zochita za melamine ndi formaldehyde.Amadziwikanso kuti melamine formaldehyde resin.Chidule cha Chingerezi ndi MF.
Zogulitsa zake ndi infusible thermosetting resins.Nthawi zambiri amatchedwa utomoni wa amino limodzi ndi urea-formaldehyde resin.
1. Utomoni wa melamine umapangidwa kukhala zinthu zopangidwa ndi mitundu yolemera, zomwe zimagwiritsidwa ntchito kwambiri popanga matabwa okongoletsera, tableware, zofunikira za tsiku ndi tsiku, ndi zina zotero. Zojambulajambula zimawoneka ngati zadothi, zosavuta kukhala zowonongeka komanso zoyenera kutsuka mbale.
2. Melamine resin ndi urea-formaldehyde resin akhoza kusakanikirana ndi zomatira, zomwe zimagwiritsidwa ntchito popanga laminates.
Ngakhale melamine utomoni ndi okwera mtengo kuposa urea utomoni, kokhamelamine utomoni (ufa mawonekedwe)akhoza kuumbidwa kukhala chakudya rade gmelamine tableware.Huafu Chemicals ndi apadera pakupanga100% kuyera melamine formaldehyde akamaumba pawiri.Takulandilani kukaona fakitale yathu ku China.
Urea-formaldehyde utomoni ndi urea ndi formaldehyde pansi zochita za chothandizira, polycondensation mu urea-formaldehyde utomoni woyamba, ndiyeno pansi pa zochita za wochiritsa kapena wothandizira kupanga insoluble ndi infusible chomaliza thermosetting utomoni.Amatchedwanso urea formaldehyde resin.Chidule cha Chingerezi UF.
1. Urea-formaldehyde utomoni wochiritsidwa ndi wopepuka, wosasunthika, wosagonjetsedwa ndi asidi wofooka ndi alkali wofooka, ntchito yabwino yotchinjiriza, kukana kwabwino kwa abrasion, ndi mtengo wotsika.Amagwiritsidwa ntchito kwambiri pazomatira.
2. Urea-formaldehyde ndi yosavuta kuwola ngati ili ndi asidi amphamvu ndi alkali wamphamvu, ndipo imakhala ndi vuto la nyengo, kuchepa kwakukulu, kuphulika kwakukulu, kusalolera kwa madzi, ndi kukalamba mosavuta.Mapanelo opangidwa ndi matabwa opangidwa ndi urea-formaldehyde resin ali ndi vuto lotulutsa formaldehyde panthawi yopanga ndikugwiritsa ntchito, chifukwa chake ayenera Kusintha.
