I-Phenolic resini-polymer yokwenziwa eyenziwe yi-condensation yama-phenol (afana ne-phenol) nama-aldehydes (njenge-formaldehyde) ngaphansi kwe-asidi noma i-base catalysis. Inokumelana nokushisa okuhle kakhulu, ukwahlukanisa namandla emishini futhi isetshenziswa kugesi, izimoto, i-aerospace neminye imikhakha.
I-Phenolic resin (i-Phenolic Resin) iyinhlaka yokwenziwa eye yenziwa ngezimboni. Yenziwa ukusabela kwe-condensation kwe-phenol noma okuphuma kuyo (okufana ne-cresol, i-xylenol) ne-formaldehyde. Ngokusho kohlobo lwe-catalyst (i-acidic noma i-alkaline) kanye nesilinganiso sezinto zokusetshenziswa, ingahlukaniswa izigaba ezimbili: i-thermoplastic ne-thermosetting. .
Izici eziyinhloko zezakhiwo:
1. Ngokuvamile kuba okuqinile okusobala okungenambala noma okuphuzi okunsundu. Imikhiqizo etholakala ngokwezentengiselwano ivamise ukwengeza ama-colorants ukwethula imibala ehlukahlukene. .
2. Inokumelana nokushisa okuvelele futhi ingasetshenziswa isikhathi eside ku-180 ℃. Yakha izinga eliphezulu lekhabhoni eliyinsalela (cishe ama-50%) ezingeni lokushisa eliphezulu. .
3. Izici zokusebenza:
Ukufakwa kukagesi okuhle kakhulu, ukubambezeleka komlilo (asikho isidingo sokwengeza izinqamuleli zomlilo) kanye nokuzinza kwe-dimensional. .
Inamandla aphezulu okusebenza, kodwa i-brittle futhi kulula ukumunca umswakama. .
4. Ukuhlelwa nokwakheka kwe-Thermoplastic phenolic resin : Isakhiwo esiwumugqa, sidinga ukwengezwa kwe-ejenti yokwelapha (efana ne-hexamethylenetetramine) ukuphambana nokwelapha. .
5. I-thermosettingPhenol-formaldehyde resin: Isakhiwo sokuxhumanisa inethiwekhi, singelapheka ngokushisisa, sinokumelana nokushisa okuphezulu namandla emishini
I-Phenolic resin isetshenziswa ikakhulukazi ukwenza amapulasitiki ahlukahlukene, okokunamathela, okunamathelisa kanye nemicu yokwenziwa.
