Phenolic resini-synthetic polymer material eyenziwa yi-condensation ye-phenols (efana ne-phenol) kunye ne-aldehydes (njenge-formaldehyde) phantsi kwe-asidi okanye i-catalysis yesiseko. Inokumelana nobushushu obugqwesileyo, i-insulation kunye namandla omatshini kwaye isetyenziselwa umbane, iimoto, i-aerospace kunye nezinye iindawo.
I-Phenolic resin (i-Phenolic Resin) yi-resin yokwenziwa esele yenziwe ngamashishini. Yenziwa yi-condensation reaction ye-phenol okanye i-derivatives yayo (efana ne-cresol, i-xylenol) kunye ne-formaldehyde. Ngokohlobo lwe-catalyst (i-acidic okanye i-alkaline) kunye nomlinganiselo wezinto eziluhlaza, inokwahlulwa ibe ngamacandelo amabini: i-thermoplastic kunye ne-thermosetting. .
Iimpawu eziphambili zomzimba:
1. Idla ngokuba yinto eqinileyo engenambala okanye emthubi emdaka obala. Iimveliso ezifumaneka ngokurhweba zihlala zongeza imibala yokubonisa imibala eyahlukeneyo. .
2. Inokumelana nobushushu obubalaseleyo kwaye ingasetyenziselwa ixesha elide kwi-180 ℃. Yenza izinga eliphezulu le-carbon eseleyo (malunga ne-50%) kwiqondo lokushisa eliphezulu. .
3. Iimpawu zokusebenza:
Ukufakelwa kombane okugqwesileyo, ukunqandwa komlilo (akukho mfuneko yokongeza i-flame retardants) kunye nokuzinza kwe-dimensional. .
Inamandla omatshini aphezulu, kodwa i-brittle kwaye kulula ukufunxa ukufuma. .
4. Ukuhlelwa kunye nesakhiwo I-Thermoplastic phenolic resin : Isakhiwo somgca, sifuna ukongezwa kwe-agent ephilisayo (efana ne-hexamethylenetetramine) ukunqumla kunye nokunyanga. .
5. ThermosettingPhenol-formaldehyde resin: Ulwakhiwo lwenethiwekhi ye-crosslinking, inokunyangwa ngokufudumeza, inokumelana nobushushu obuphezulu kunye namandla omatshini
I-phenolic resin isetyenziswa ikakhulu ukwenza iiplastiki ezahlukeneyo, iingubo, izinto zokuncamathelisa kunye neentsinga zokwenziwa.
