Melamine resin yog ib qho polymer tau los ntawm cov tshuaj tiv thaiv ntawm melamine thiab formaldehyde.Nws tseem hu ua melamine formaldehyde resin.Lus Askiv yog MF.
Nws cov khoom yog infusible thermosetting resins.Nws feem ntau hu ua amino resin ua ke nrog urea-formaldehyde resin.
1. Melamine resin yog tsim los ua cov khoom molded nrog cov xim nplua nuj, feem ntau yog siv rau hauv cov khoom siv kho kom zoo nkauj, cov tais diav, cov khoom siv niaj hnub, thiab lwm yam. Cov tais diav zoo li cov plooj (porcelain), tsis yooj yim rau nkig thiab haum rau kev ntxuav tais diav.
2. Melamine resin thiab urea-formaldehyde resin tuaj yeem sib xyaw rau hauv cov nplaum, uas yog siv los ua laminates.
Txawm hais tias melamine resin yog kim dua li urea resin, tsuas yogmelamine resin (Powder form)tuaj yeem molded rau hauv cov zaub mov rade gmelamine tableware.Huafu Chemicals yog tshwj xeeb hauv kev tsim khoom ntawm100% purity melamine formaldehyde molding compound.Txais tos tuaj xyuas peb lub Hoobkas hauv Suav teb.
Urea-formaldehyde resin yog urea thiab formaldehyde nyob rau hauv qhov kev txiav txim ntawm lub catalyst, polycondensation rau hauv thawj zaug urea-formaldehyde resin, thiab tom qab ntawd nyob rau hauv qhov kev txiav txim ntawm tus neeg sawv cev kho los yog tus neeg sawv cev pabcuam los tsim ib qho insoluble thiab infusible kawg thermosetting resin.Kuj tseem hu ua urea formaldehyde resin.Cov lus Askiv luv UF.
1. Cov kho urea-formaldehyde resin yog lub teeb xim, translucent, resistant rau qaug zog acid thiab alkali tsis muaj zog, zoo rwb thaiv tsev kev ua tau zoo, zoo heev abrasion kuj, thiab tus nqi qis.Nws yog dav siv nyob rau hauv adhesives.
2. Urea-formaldehyde yog ib qho yooj yim rau decompose nyob rau hauv cov ntaub ntawv uas muaj zog acid thiab muaj zog alkali, thiab muaj cov huab cua tsis zoo, shrinkage loj, siab brittleness, dej intolerance, thiab yooj yim aging.Ntoo-raws li panels tsim nrog urea-formaldehyde resin muaj teeb meem ntawm formaldehyde tso tawm thaum lub sij hawm tsim thiab siv cov txheej txheem, yog li nws yuav tsum Hloov kho nws.
