Khoom Piav Qhia
Urea-formaldehyde cob (UF), tseem hu ua urea-formatherhyde resin, thiab tom qab ntawd acidichyde resin, thiab tom qab ntawd cov acc aus Thermosetting resin. Kho urerea-formaldehyde cob yog ntais ntawv ntau dua cov kua qaub tsis muaj zog, muaj cov rwb thaiv tsev zoo, thiab yog pheej yig. Nws yog qhov feem ntau siv ntau yam ntawm cov nplaum, tshwj xeeb hauv kev tsim khoom ntawm ntau cov khoom lag luam ntoo hauv kev ua lag luam ntoo ua haujlwm rau 90% ntawm tag nrho cov nplaum siv. However, urea-formaldehyde resin is easy to decompose when exposed to strong acids and alkalis. It has poor weather resistance, poor initial viscosity, large shrinkage, brittleness, water resistance, and easy aging. Artificial boards produced with urea-formaldehyde resin release formaldehyde during the manufacturing and use process. problem, so it must be modified.

Daim ntawv thov
Nws tuaj yeem siv tau hauv cov khoom uas tsis tas yuav tau cov dej tsis kam ua, xws li cov ntaub ntawv tso quav, thiab tuaj yeem siv rau hauv cov khoom lag luam ntawm qee cov tableware.

Urea-formaldehyde resin is the most commonly used type of adhesive. Tshwj xeeb tshaj yog nyob rau hauv kev tsim khoom ntawm ntau lub chaw tsim khoom hauv kev ua ntoo ua ke, urea-formaldehyde resin thiab nws cov khoom siv hloov kho rau txog 90% ntawm tag nrho cov nplaum siv.
