Phenolic resinhe rauemi polymer waihanga i hangaia e te tohanga o te phenols (pēnei i te phenol) me te aldehydes (pēnei i te formaldehyde) i raro i te waikawa, te papahanga catalysis ranei. He pai te wera o te wera, te whakamaarama me te kaha miihini, ka whakamahia i roto i te hiko, te miihini, te aerospace me etahi atu mara.
Ko te kapia Phenolic (Phenolic Resin) he kapia waihanga kua hangaia ki te ahumahi. He mea hanga na roto i te tauhohenga whakamaaramatanga o te phenol, o ona hua ranei (pēnei i te cresol, xylenol) me te formaldehyde. E ai ki te momo whakakōkī (waikawa, kawakore rānei) me te ōwehenga o ngā rauemi mata, ka taea te wehea ki ngā kāwai e rua: thermoplastic me te thermosetting. ?
Āhuatanga matua:
1. I te nuinga o te wa he totoka kore tae, he kowhai parauri ranei. Ko nga hua e waatea ana ki te hokohoko he taapiri i nga tae hei whakaatu i nga momo tae. ?
2. He tino pai te parenga wera ka taea te whakamahi mo te wa roa i te 180 ℃. Ka hanga he reeti waro toenga teitei (tata ki te 50%) i te pāmahana teitei. ?
3. Nga ahuatanga mahi:
He pai te whakamaarama hiko, te mura o te mura (kaore e hiahiatia te taapiri i nga parepare mura) me te pumau o te taha. ?
He kaha te kaha o te miihini, engari he pakarukaru, he ngawari ki te tango i te makuku. ?
4. Whakar ?
5. ThermosettingPhenol-formaldehyde resin : Ko te hanganga honohono whatunga, ka taea te rongoa ma te whakamahana, he teitei ake te wera me te kaha miihini
Ka whakamahia te kapia Phenolic ki te hanga i nga momo kirihou, paninga, whakapiri me nga muka waihanga.
