Nguwuphi umahluko phakathi kweMelamine Resin kunye neUrea Resin?

I-Melamine resin yipolymer efunyenwe ngokusabela kwe-melamine kunye ne-formaldehyde.Ikwabizwa ngokuba yi-melamine formaldehyde resin.Isishunqulelo sesiNgesi sithi MF.

Iimveliso zayo ziyi-resin thermosetting resins.Ihlala ibizwa ngokuba yi-amino resin kunye ne-urea-formaldehyde resin.

1. I-Melamine resin yenziwe kwiimveliso ezibunjiweyo ezinemibala ecebileyo, esetyenziswa kakhulu kwimveliso yeebhodi zokuhombisa, i-tableware, iimfuno zemihla ngemihla, njl njl. I-tableware ibonakala ngathi i-porcelain, akulula ukuba ibe yi-brittle kwaye ifanele ukuhlamba i-dishwasher.

2. I-resin ye-melamine kunye ne-urea-formaldehyde resin inokuxutywa kwii-adhesives, ezisetyenziselwa ukwenza i-laminates.

Nangona i-melamine resin ibiza kakhulu kune-urea resin, kuphelaI-melamine resin (ifomu yomgubo)inokubunjwa ibe rade ukutya gmelamine tableware.I-Huafu Chemicals ikhethekileyo kwimveliso ye100% ubumsulwa melamine formaldehyde ikhompawundi yokubumba.Wamkelekile ukutyelela umzi-mveliso wethu eTshayina.

I-resin ye-Urea-formaldehyde yi-urea kunye ne-formaldehyde phantsi kwesenzo se-catalyst, i-polycondensation ibe yi-resin yokuqala ye-urea-formaldehyde, kwaye emva koko phantsi kwesenzo se-agent ephilisayo okanye i-agent encedisayo ukwenza i-resin engapheliyo kunye ne-infusible yokugqibela ye-thermosetting.Ikwabizwa ngokuba yi-urea formaldehyde resin.Isishunqulelo sesiNgesi esithi UF.

1. I-resin ye-urea-formaldehyde ephilileyo ilula ngombala, iguquguqukayo, iyamelana ne-asidi ebuthakathaka kunye ne-alkali ebuthakathaka, ukusebenza kakuhle kwe-insulation, ukuxhathisa okuphezulu kwe-abrasion, kunye nexabiso eliphantsi.Isetyenziswa kakhulu kwi-adhesives.

2. IUrea-formaldehyde kulula ukubola xa kukho iasidi eyomeleleyo kunye nealkali eyomeleleyo, kwaye inokumelana nemozulu embi, ukushwabana okukhulu, ubuqhophololo obuphezulu, ukunganyamezeli kwamanzi, kunye nokuguga lula.Iipaneli ezisekelwe kwiplanga eziveliswe nge-urea-formaldehyde resin zinengxaki yokukhutshwa kwe-formaldehyde ngexesha lokuvelisa kunye nokusetyenziswa kwenkqubo, ngoko kufuneka iLunge.
