I-resin ye-phenolicyi-polymer eyenziweyo eyenziwe ngokuxinana kwee-phenols (ezifana ne-phenol) kunye nee-aldehydes (ezifana ne-formaldehyde) phantsi kwe-asidi okanye i-base catalysis. Inokumelana nobushushu okugqwesileyo, ukugquma kunye namandla oomatshini kwaye isetyenziswa kumbane, kwiimoto, kwi-aerospace nakwezinye iindawo.
I-Phenolic resin (i-Phenolic Resin) yi-synthetic resin eye yaphuhliswa kwimizi-mveliso. Yenziwa yi-condensation reaction ye-phenol okanye izinto eziphuma kuyo (ezifana ne-cresol, i-xylenol) kunye ne-formaldehyde. Ngokwe-catalyst (i-acidic okanye i-alkaline) kunye nomlinganiselo wezinto ezikrwada, inokwahlulwa ibe ngamacandelo amabini: i-thermoplastic kunye ne-thermosetting.
Iimpawu eziphambili Iimpawu zomzimba:
1. Ihlala iyinto eqinileyo engenambala okanye etyheli mdaka ecacileyo. Iimveliso ezithengiswayo zihlala zongeza izinto ezifaka imibala ukuze zibonise imibala eyahlukeneyo.
2. Inokumelana okugqwesileyo nobushushu kwaye ingasetyenziswa ixesha elide kwi-180℃. Yenza isantya esiphezulu sekhabhoni eseleyo (malunga ne-50%) kubushushu obuphezulu.
3. Iimpawu zokusebenza:
Ubushushu obugqwesileyo bombane, ukucotha komlilo (akukho mfuneko yokongeza izinto ezicothayo umlilo) kunye nozinzo olulinganayo.
Inamandla aphezulu oomatshini, kodwa ibuthathaka kwaye kulula ukufunxa umswakama.
4. Uhlu kunye nolwakhiwo I-thermoplastic phenolic resin : Ulwakhiwo olucwangcisiweyo, lufuna ukongezwa kwe-ejenti yokuphilisa (efana ne-hexamethylenetetramine) kwi-crosslink kunye ne-cure.
5. Ukuseta i-thermosettingI-resin yePhenol-formaldehydeIsakhiwo sokudibanisa inethiwekhi, sinokunyangwa ngokufudumeza, sinokuxhathisa ubushushu obuphezulu kunye namandla oomatshini
I-resin ye-phenolic isetyenziswa kakhulu ekwenzeni iiplastiki ezahlukeneyo, izinto zokugquma, izinto zokuncamathelisa kunye neefayibha zokwenziwa.
