1. Chidule cha urea-formaldehyde resin (UF)
Urea-formaldehyde resin, yomwe imatchedwa UF, imagwiritsidwa ntchito kwambiri pomanga matabwa ndipo yalimbikitsa ntchito zazikulu popanga plywood ndi particleboard.
2. Makhalidwe
Urea-formaldehyde utomoni umakondedwa chifukwa cha zinthu zake zambiri zopangira komanso mtengo wotsika. Ili ndi zomatira bwino kwambiri, imalimbana ndi ma acid ofooka ndi ma alkalis ofooka, ndipo imawonetsa kutchinjiriza bwino komanso kukana kuvala. Komabe, ndikofunikira kudziwa kuti formaldehyde imatulutsidwa panthawi yochiritsa, ndipo kukana kwake kutentha ndi kukana kukalamba kumakhala kofooka.
3. Fomu
Urea-formaldehyde utomoniikhoza kuperekedwa m'njira zosiyanasiyana monga utomoni, ufa, bolodi ndi zomatira kuti zikwaniritse zofunikira zosiyanasiyana.
4. Njira zoyenera
Urea-formaldehyde utomoni ndi oyenera njira zosiyanasiyana monga ❖ kuyanika ndi kuponderezana akamaumba, kupereka thandizo popanga zinthu zosiyanasiyana.
5. Kugwiritsa ntchito
Monga guluu yemwe amagwiritsidwa ntchito kwambiri pamakampani opanga matabwa,urea-formaldehyde utomoniamagwiritsidwa ntchito kwambiri pomanga matabwa, plywood, laminates, ndi nsungwi ndi matabwa. Mwachitsanzo, amagwiritsidwa ntchito popanga zigoba zamatabwa zapansi, mipando, mabokosi oyikamo, zida za nsalu, ndi zida zapakhomo.
1. Limbikitsani kukana kwamadzi kwa zomatira za urea-formaldehyde resin: Powonjezera zolumikizira zolumikizirana monga aluminium sulfate ndi aluminium phosphate, kukana kwake kwamadzi kumatha kuwongolera bwino.
2. Limbikitsani kukana kukalamba: Kusakaniza utomoni wina wa thermoplastic mu zomatira za urea-formaldehyde utomoni zimatha kusintha kwambiri kukana kwawo kukalamba.
3. Chepetsani zinthu za formaldehyde: Mwa kusintha ndondomeko ya kaphatikizidwe, kuchepetsa chiwerengero cha molar cha formaldehyde ku urea, kapena kuwonjezera zowononga za formaldehyde (monga urea, melamine, etc.), cholinga chochepetsera zomwe zili mu urea-formaldehyde resin adhesives zikhoza kutheka.
Aojin Chemical amagulitsa urea-formaldehyde utomoni wapamwamba kwambiri wokhala ndi zinthu zapamwamba kwambiri. Kupereka ku makampani opanga mipando ndi makampani opanga ma board. Pezani mtengo wabwino kwambiri wa urea-formaldehyde resin tsopano, funsani Aojin Chemical mwachangu!
