te kapia phenolicHe rauemi pūmua hangai tēnei i hangaia mā te whakakotahitanga o ngā phenols (pērā i te phenol) me ngā aldehydes (pērā i te formaldehyde) i raro i te waikawa, i te turanga rānei. He tino pai tōna ātete ki te wera, ki te whakamarumaru me te kaha miihini, ā, e whakamahia ana i roto i ngā mahi hiko, motuka, rererangi me ētahi atu mara.
Ko te kapia phenolic (Phenolic Resin) he kapia hangai kua whakapūmautia ki te ahumahi. Ka hangaia mā te tauhohenga whakapūmau o te phenol, ōna rānei ira (pērā i te cresol, xylenol) me te formaldehyde. E ai ki te momo whakakorikori (waikawa, kawakore rānei) me te ōwehenga o ngā rauemi mata, ka taea te wehewehe kia rua ngā wāhanga: te thermoplastic me te thermosetting.
Ngā āhuatanga matua Ngā āhuatanga ā-tinana:
1. He mea totoka mārama, kāore he tae, he parauri kōwhai rānei. He maha ngā wā ka tāpirihia he tae ki ngā hua hokohoko hei whakaatu i ngā momo tae.
2. He tino ātete ki te wera, ā, ka taea te whakamahi mō te wā roa i te 180℃. He nui te reiti waro toenga ka puta (tata ki te 50%) i te pāmahana teitei.
3. Ngā āhuatanga mahi:
He pai rawa te ārai hiko, te ātete mura (kāore e hiahiatia he ārai mura) me te pumau o ngā āhuatanga.
He kaha rawa tōna ki te whakamahi i ngā mīhini, engari he pakarukaru, ā, he ngāwari ki te mimiti i te makuku.
4. Te whakarōpūtanga me te hanganga te kapia phenolic thermoplastic : Te hanganga rārangi, me tāpiri he matū whakaora (pērā i te hexamethylenetetramine) hei hono me te whakaora.
5. WhakamahanaKapia phenol-formaldehyde: He hanganga hononga whatunga, ka taea te whakaora mā te whakamahana, he ātete wera nui ake, he kaha hoki
Ko te kapia phenolic e whakamahia nuitia ana hei hanga i ngā momo kirihou, paninga, piripiri me ngā muka hangai.
