1. Kakaretso ea urea-formaldehyde resin (UF)
Urea-formaldehyde resin, eo ho thoeng ke UF, e sebelisoa hangata bakeng sa ho kopanya lehong mme e khothalelitse ts'ebeliso e kholo tlhahisong ea plywood le particleboard.
2. Litšobotsi
Urea-formaldehyde resin e ratoa ka lebaka la thepa ea eona e tala le theko e tlase. E na le ho khomarela ka tsela e babatsehang, e hanyetsana le li-acid tse fokolang le li-alkali tse fokolang, 'me e bonts'a ho kenya letsoho hantle le ho hanyetsa ho apara. Leha ho le joalo, ke habohlokoa ho hlokomela hore formaldehyde e lokolloa nakong ea ts'ebetso ea eona ea ho folisa, 'me ho hanyetsa mocheso le ho tsofala ha eona ho batla ho fokola.
3. Sebopeho
Resin ea urea-formaldehydee ka hlahisoa ka mefuta e fapaneng e kang resin, phofo, boto le sekhomaretsi ho fihlela litlhoko tse fapaneng tsa kopo.
4. Mekhoa e sebetsang
Urea-formaldehyde resin e loketse lits'ebetso tse fapaneng tse kang ho roala le ho bopa ha compression, ho fana ka ts'ehetso bakeng sa tlhahiso ea lihlahisoa tse fapaneng.
5. Kopo
E le sekhomaretsi se sebelisoang haholo indastering ea ho lokisa lehong,resin ea urea-formaldehydee sebelisoa haholo ho kopanya lehong, plywood, laminates, le bamboo le lihlahisoa tsa lehong. Ka mohlala, e sebelisetsoa ho etsa likhetla tsa lepolanka tsa fuluru, thepa ea ka tlung, mabokose a ho paka, thepa ea masela le lisebelisoa tsa ka tlung.
1. Ntlafatsa ho hanyetsa metsi ka sekhomaretsi sa resin ea urea-formaldehyde: Ka ho eketsa li-cross-linking agents tse kang aluminium sulfate le aluminium phosphate, ho hanyetsa metsi a eona ho ka ntlafatsoa ka katleho.
2. Ntlafatsa khanyetso ea botsofali: Ho kopanya li-resin tse ling tsa thermoplastic ho li-adhesive tsa urea-formaldehyde resin ho ka ntlafatsa haholo ho hanyetsa ha tsona ho tsofala.
3. Fokotsa litaba tsa formaldehyde: Ka ho lokisa mokhoa oa ho kopanya, ho fokotsa tekanyo ea molar ea formaldehyde ho urea, kapa ho eketsa li-scavengers tsa formaldehyde (tse kang urea, melamine, joalo-joalo), morero oa ho fokotsa litaba tsa formaldehyde ka li-adhesive tsa urea-formaldehyde resin li ka finyelloa.
Aojin Chemical e rekisa li-resin tsa boleng bo holimo tsa urea-formaldehyde tse nang le maemo a holimo a sehlahisoa. Phepelo ho indasteri ea thepa ea ka tlung le indastering ea boto. Fumana theko e ntle ka ho fetisisa ea urea-formaldehyde resin hona joale, ikopanye le Aojin Chemical kapele!
