ʻO ka resin phenolicHe mea polymer synthetic i hoʻokumu ʻia e ka condensation o nā phenols (e like me ka phenol) a me nā aldehydes (e like me ka formaldehyde) ma lalo o ka catalysis waikawa a i ʻole ke kumu. Loaʻa iā ia ke kūpaʻa wela maikaʻi loa, ka insulation a me ka ikaika mechanical a hoʻohana ʻia i nā ʻoihana uila, kaʻa, aerospace a me nā ʻoihana ʻē aʻe.
ʻO ka resin Phenolic (Phenolic Resin) kahi resin synthetic i hoʻomohala ʻia. Hana ʻia ia e ka hopena condensation o ka phenol a i ʻole kāna mau derivatives (e like me cresol, xylenol) a me formaldehyde. Wahi a ke ʻano o ka catalyst (acidic a alkaline paha) a me ka ratio o nā mea maka, hiki ke hoʻokaʻawale ʻia i ʻelua mau māhele: thermoplastic a me thermosetting.
Nā ʻano nui Nā ʻano kino:
1. He mea paʻa aniani ʻole a melemele paha ia. Hoʻohui pinepine nā huahana i loaʻa ma ke kālepa i nā mea hoʻoluʻu e hōʻike i nā ʻano kala like ʻole.
2. Loaʻa iā ia ke kūpaʻa wela maikaʻi loa a hiki ke hoʻohana ʻia no ka manawa lōʻihi ma 180℃. Hoʻokumu ia i kahi helu kalapona koena kiʻekiʻe (ma kahi o 50%) ma ke ana wela kiʻekiʻe.
3. Nā ʻano hana:
ʻO ka pale uila maikaʻi loa, ka pale ʻana i ka lapalapa (ʻaʻohe pono e hoʻohui i nā mea pale lapalapa) a me ke kūpaʻa o ka nui.
He ikaika mīkini kiʻekiʻe kona, akā he palupalu a maʻalahi hoʻi e omo i ka makū.
4. Ka hoʻokaʻawale ʻana a me ke ʻano Thermoplastic phenolic resin : ʻO ke ʻano linear, pono ka hoʻohui ʻana o ka mea hoʻōla (e like me hexamethylenetetramine) e hoʻopili a hoʻōla.
5. Hoʻonohonoho ThermoʻO ka resin Phenol-formaldehyde: ʻO ke ʻano crosslinking pūnaewele, hiki ke ho'ōla ʻia e ka hoʻomehana ʻana, ʻoi aku ka kiʻekiʻe o ke kūpaʻa wela a me ka ikaika mechanical
Hoʻohana nui ʻia ka resin Phenolic e hana i nā ʻano plastik like ʻole, nā uhi, nā mea hoʻopili a me nā fiber synthetic.
