I-Melamine resin iyi-polymer etholakala ngokusabela kwe-melamine ne-formaldehyde.Yaziwa nangokuthi i-melamine formaldehyde resin.Isifinyezo sesiNgisi sithi MF.
Imikhiqizo yayo i-infusible thermosetting resins.Ivame ukubizwa ngokuthi i-amino resin kanye ne-urea-formaldehyde resin.
1. I-Melamine resin yenziwe imikhiqizo ebunjiwe enemibala ecebile, esetshenziswa kakhulu ekukhiqizeni amabhodi okuhlobisa, i-tableware, izidingo zansuku zonke, njll. I-tableware ibonakala njenge-porcelain, akulula ukuba ibe brittle futhi ifanele ukugeza izitsha.
2. I-melamine resin kanye ne-urea-formaldehyde resin ingaxutshwa zibe izinto zokunamathisela, ezisetshenziselwa ukwenza ama-laminates.
Nakuba i-melamine resin ibiza kakhulu kune-urea resin, kuphelaI-melamine resin (ifomu le-powder)ingabunjwa ibe rade ukudla gmelamine tableware.I-Huafu Chemicals ikhethekile ekukhiqizeniI-100% ubumsulwa be-melamine formaldehyde molding compound.Siyakwamukela ukuvakashela imboni yethu e-China.
I-Urea-formaldehyde resin yi-urea ne-formaldehyde ngaphansi kwesenzo se-catalyst, i-polycondensation ibe yinhlaka yokuqala ye-urea-formaldehyde, bese ingaphansi kwesenzo se-ejenti elaphayo noma i-ejenti eyisizayo ukwakha inhlaka yokugcina engabizi futhi engenakunyakaziswa ye-thermosetting.Eyaziwa nangokuthi i-urea formaldehyde resin.Isifinyezo sesiNgisi esithi UF.
1. I-urea-formaldehyde resin eselashiwe inombala okhanyayo, iyashintshashintsha, imelana ne-asidi ebuthakathaka kanye ne-alkali ebuthakathaka, ukusebenza kahle kokufakwa kwe-insulation, ukumelana okuhle kakhulu kokuhuzuka, kanye nenani eliphansi.Isetshenziswa kabanzi kuma-adhesives.
2. I-Urea-formaldehyde kulula ukubola uma kune-asidi eqinile ne-alkali enamandla, futhi inokumelana nesimo sezulu esibi, ukushwabana okukhulu, ukonakala okukhulu, ukungabekezeleli amanzi, nokuguga kalula.Amaphaneli asekelwe ngokhuni akhiqizwe nge-urea-formaldehyde resin anenkinga yokukhishwa kwe-formaldehyde ngesikhathi sokukhiqiza nokusetshenziswa, ngakho-ke kufanele Ayiguqule.
