Chimiro cheUF chimbuzi chigaro

Urea formaldehyde (UFï¼ ‰ chigaro chechimbuziinonyanya kushandiswa kugadzirira amino alkyd kubheka pendi ne alkyd resin kuvandudza kuoma uye kuoma kwepende yefirimu. Chigaro chechimbuzi cheUF chinogona kusanganiswa neisingaomesi alkyd resin kugadzira asidhi inorapa amino pendi, inogona kushandiswa kuvharisa mwenje wehuni fenicha. Asi kusamira kwemamiriro ekunze, kusamira kwemvura uye nekuchengetedza chiedza zvishoma zvishoma. Epoxy resin uye alkyd resin inogona kushandiswa kugadzira maprimers uye pendi yemukati ine zvinhu zvakasiyana. Zvinhu zvikuru zvinosanganisira:

1. Mutengo wechigaro chechimbuzi cheUFyakachipa uye midziyo yakakwana.

2. The molecular chimiro cheurea formaldehyde(UF)chimbuzi chigaroine polar maatomu eokisijeni, saka ine yakanaka kunamatira kumusoro. Inogona kushandiswa kune primer uye yepakati coating kuvandudza kunamatira pakati petopcoat.

3. NokutiUF chimbuzi chigaroinogona kurapwa pakupisa kwekamuri kana uchishandisa acid catalyst, inogona kushandiswa kune maviri-chikamu chehuni coatings.

4. Firimu yepende inorapwa neurea formaldehyde resin ine yakanaka kushanduka.

5. Urea formaldehyde resin ine high viscosity, high acid value uye kusagadzikana kwekuchengetedza.
