N-Methylolacrylamide CAS:924-42-5

N-Methylolacrylamide (NMA) e sebeletsa mesebetsi e fapaneng liindastering tse ngata ka lebaka la thepa ea eona e feto-fetohang. Lefapheng la tlhahiso ea polymer, e sebetsa e le monomer bakeng sa tlhahiso ea li-polymer tse khethehileng le li-copolymer tse nang le khokahano e ntlafalitsoeng, matla le ho tšoarella. Li-polymer tsena li fumana ts'ebeliso ho likhomaretsi, liphahlo, masela le thepa ea kaho, e tlatsetsang ts'ebetsong e ntlafetseng ea thepa le ho feto-fetoha ha lintho. Ho feta moo, N-methylolacrylamide e sebelisoa ho etseng li-auxiliaries tsa pampiri le masela, e sebetsa e le moemeli oa ho hokahanya le ho fetola. Bokhoni ba eona ba ho hokahanya likhoele tsa cellulose bo ntlafatsa matla a pampiri, thepa ea ho khomarela e mongobo, le ho hanyetsa botsofali, e tlatsetsa tlhahisong ea lihlahisoa tsa pampiri tsa boleng bo holimo bakeng sa lits'ebetso tsa khatiso le liphutheloana. Tlhahisong ea li-resin le liphahlo, N-methylolacrylamide e bapala karolo ea bohlokoa tlhahisong ea li-resin le liphahlo tsa thermosetting. Ho sebetsa hantle ha eona le ho lumellana ha eona ho etsa hore e be ea bohlokoa bakeng sa ho ntlafatsa ho khomarela, ho hanyetsa tšusumetso, le botsitso ba lik'hemik'hale ba liphahlo tse sebelisoang lits'ebetsong tsa likoloi, lifofane le indasteri. Ho feta moo, e sebelisoa e le tlatsetso e sebetsang tlhahisong ea liphetho tsa letlalo le masela, e tlatsetsa ho ntlafatseng ho tšoarella, ho hanela metsi le ho potlaka ha 'mala oa thepa e phekotsoeng. Ho kenyelletsoa ha eona mefuteng ea ho qetela ho thusa ho theheng thepa ea letlalo le masela a boleng bo holimo bakeng sa feshene, upholstery le lits'ebetso tsa indasteri. Ho feta moo, N-methylolacrylamide e sebetsa e le karolo ea ho kopanya lik'hemik'hale tse ikhethang le li-additi tse sebelisoang lits'ebetsong tse fapaneng tsa indasteri. Ho sebetsana ha eona le lik'hemik'hale le ho lumellana ha eona le metsoako e meng ho e etsa hore e be molemo bakeng sa ho theha liforomo tse ikhethileng tse etselitsoeng litlhoko tse itseng tsa indasteri. Ho feta moo, e sebelisoa tlhahisong ea lik'hemik'hale tsa oli, moo e sebetsang e le mohlophisi oa rheology le moemeli oa taolo ea tahlehelo ea mokelikeli marong a ho cheka. Litšobotsi tsa eona li kenya letsoho botsitsong le ts'ebetsong ea li-drill tse sebelisoang lipatlisisong tsa oli le khase le ts'ebetsong ea tlhahiso. Ka kakaretso, lits'ebetso tse fapaneng tsa N-methylolacrylamide li kenyelletsa tlhahiso ea polymer, li-auxiliaries tsa pampiri le masela, li-resin le li-coat, liphetho tsa letlalo le masela, lik'hemik'hale tse ikhethang, le lik'hemik'hale tsa oli. Litšobotsi tsa eona tse feto-fetohang li kenya letsoho ho ntlafatseng ts'ebetso ea thepa, ho nolofatsa ts'ebetso e sebetsang, le ho nolofalletsa tlhahiso ea lisebelisoa tse tsoetseng pele liindastering tse ngata.
