Phenolic resinke thepa ea maiketsetso ea polymer e entsoeng ke condensation ea phenols (e kang phenol) le aldehydes (joaloka formaldehyde) tlas'a acid kapa catalysis ea motheo. E na le ho hanyetsa mocheso o babatsehang, ho kenya letsoho le matla a mochine 'me e sebelisoa libakeng tsa motlakase, tsa likoloi, tsa sefofane le tse ling.
Phenolic resin (Phenolic Resin) ke resin ea maiketsetso e entsoeng indastering. E entsoe ke karabelo ea condensation ea phenol kapa li-derivatives tsa eona (joalo ka cresol, xylenol) le formaldehyde. Ho ea ka mofuta oa catalyst (acidic kapa alkaline) le karo-karolelano ea thepa e tala, e ka aroloa ka mekhahlelo e 'meli: thermoplastic le thermosetting. '
Litšobotsi tse ka sehloohong tsa 'mele:
1. Hangata ha e na 'mala kapa bosehla bo sootho bo bonaletsang bo tiileng. Lihlahisoa tse fumanehang khoebong hangata li eketsa mebala ho hlahisa mebala e fapaneng. '
2. E na le ho hanyetsa mocheso o ikhethang 'me e ka sebelisoa nako e telele ho 180 ℃. E theha sekhahla se phahameng sa khabone (e ka bang 50%) mochesong o phahameng. '
3. Litšobotsi tsa ts'ebetso:
Motlakase o motle haholo, ho lieha ha lelakabe (ha ho na tlhoko ea ho eketsa li-retardants tsa lelakabe) le botsitso ba sebopeho. '
E na le matla a phahameng a mochini, empa e brittle ebile e bonolo ho monya mongobo. '
4. Classification and structure Thermoplastic phenolic resin : Sebopeho sa linear, se hloka ho eketsoa ha moriana (joaloka hexamethylenetetramine) ho tšela le ho phekola. '
5. ThermosettingPhenol-formaldehyde resin: Sebopeho sa marang-rang sa marang-rang, se ka phekoloa ka ho futhumatsa, se na le mocheso o phahameng oa ho hanyetsa le matla a mochine
Phenolic resin e sebelisoa haholo ho etsa lipolasetiki tse fapaneng, likoahelo, likhomaretsi le likhoele tsa maiketsetso.
