Ingcaciso yeMveliso
I-Urea-formaldehyde resin (UF), ekwaziwa njenge-urea-formaldehyde resin, yi-polycondensation ye-urea kunye ne-formaldehyde phantsi kwesenzo se-catalyst (i-alkaline okanye i-acidic catalyst) ukuze yenze i-urea-formaldehyde resin yokuqala, kwaye emva koko yenza into enganyibilikiyo kunye ne-infusible yesigaba sokugqibela sokudibanisa okanye sokudibanisa. I-resin ye-thermosetting. Iresin ye-urea-formaldehyde enyangisiweyo ikhaphukhaphu ngombala kune-phenolic resin, iyaguquguquka, iyamelana neeasidi ezibuthathaka kunye nealkali ebuthathaka, ineempawu ezilungileyo zokugquma, ukumelana nokunxiba okugqwesileyo, kwaye inexabiso eliphantsi. Lolona didi luqhelekileyo lusetyenziswayo phakathi kwezinto zokuncamathelisa, ngakumbi ekwenziweni kweebhodi ezahlukeneyo ezenziweyo kwishishini lokulungisa iinkuni, i-urea-formaldehyde resin kunye neemveliso zayo eziguquliweyo zithatha malunga ne-90% yokusetyenziswa kokuncamatheliswa kukonke. Nangona kunjalo, i-urea-formaldehyde resin kulula ukubola xa ibonakaliswe kwi-acids eqinile kunye ne-alkalis. Inokumelana nemozulu embi, i-viscosity yokuqala engalunganga, ukushwabana okukhulu, i-brittleness, ukumelana namanzi, kunye nokuguga lula. Iibhodi ezenziweyo eziveliswe nge-urea-formaldehyde resin ikhupha i-formaldehyde ngexesha lokwenziwa kunye nokusetyenziswa kwenkqubo. ingxaki, ngoko kufuneka iguqulwe.
Isicelo
Ingasetyenziswa kwiimveliso ezingafunekiyo ukumelana namanzi aphezulu kunye neempawu ze-dielectric, ezinje ngemigca yamandla, iiswitshi, izibambo zoomatshini, ii-casings zesixhobo, amaqhina, iimfuno zemihla ngemihla, imihombiso, iithayile ze-mahjong, iziciko zendlu yangasese, kwaye ingasetyenziselwa ukwenza ezinye izinto zetafile.
Iresin ye-Urea-formaldehyde lolona hlobo lusetyenziswa ngokuqhelekileyo lokuncamathelisa. Ngokukodwa xa kusenziwa iibhodi ezenziweyo ezahlukeneyo kwishishini lokulungisa iinkuni, intlaka ye-urea-formaldehyde kunye neemveliso zayo ezilungisiweyo zithatha malunga ne-90% yokusetyenziswa kokuncamatheliswa.
