የምርት መግለጫ
Urea-formaldehyde resin (UF), also known as urea-formaldehyde resin, is the polycondensation of urea and formaldehyde under the action of a catalyst (alkaline or acidic catalyst) to form an initial urea-formaldehyde resin, and then forms an insoluble and infusible final phase under the action of a curing agent or additive. Tramocking Statin. Cured urea-formaldehyde resin is lighter in color than phenolic resin, translucent, resistant to weak acids and weak alkali, has good insulation properties, excellent wear resistance, and is cheap. It is the most commonly used variety among adhesives, especially in In the manufacturing of various artificial boards in the wood processing industry, urea-formaldehyde resin and its modified products account for about 90% of the total adhesive usage. ሆኖም, ኡሬ-ፎምመዲዲዲዲድ ለጠንካራ አሲዶች እና ለአልካሊስ ሲጋለጡ በቀላሉ ለመበስበስ ቀላል ነው. ደካማ የአየር ሁኔታ መቋቋም, ደካማ የመጀመሪያ እይታ, ትልልቅ ሽፋኖች, ጨዋነት, የውሃ መቋቋም እና ቀላል አረጋዊ. በማኑፋክቸሪንግ እና በሚጠቀሙበት ሂደት ውስጥ ከዩና-ፎርማዲዲዲዲዲዲ ጋር የሚመጡ የአስራሽ ሰሌዳዎች. ችግር, ስለዚህ መሻሻል አለበት.
