ʻenehana hana a me ka hana o ka bakelite

1. Mea maka
1.1 Mea-Bakelite
ʻO ka inoa kemika o Bakelite he phenolic plastic, ʻo ia ke ʻano mua o ka plastic i hoʻokomo ʻia i loko o ka hana ʻoihana.Loaʻa iā ia ka ikaika mechanical kiʻekiʻe, ka insulation maikaʻi, ka wela a me ka corrosion resistance, no laila e hoʻohana pinepineʻia i ka hanaʻana i nā mea uila, e like me nā hoʻololi, nā kukui kukui, nā pepeiao pepeiao, nā pahu kelepona, nā mea kani, a pēlā aku.He mea koʻikoʻi kona hiki ʻana mai i ka hoʻomohala ʻoihana.
1.2 Keʻano Bakelite
Hiki ke hana ʻia nā pūhui phenolic a me aldehyde i resin phenolic e ka hopena condensation ma lalo o ka hana a ka acidic a i ʻole ka catalyst kumu.Hoʻohui i ka resin phenolic me ka pauka lāʻau sawn, talcum powder (filler), urotropine (curing agent), stearic acid (lubricant), pigment, etc., a me ka wela a hui i loko o kahi hui e loaʻa ai ka pauka Bakelite.Hoʻomaʻamaʻa ʻia ka pauka bakelite a kaomi ʻia i loko o kahi ʻāpana e loaʻa ai kahi huahana plastic phenolic thermosetting.

2. Nā ʻano o ka bakelite
ʻO nā hiʻohiʻona o ka bakelite he non absorbent, non-conductive, pale wela kiʻekiʻe a me ka ikaika kiʻekiʻe.Hoʻohana pinepine ʻia i nā mea uila, no laila ua kapa ʻia ʻo "bakelite".Hana ʻia ʻo Bakelite me ka pauka phenolic resin, i hui pū ʻia me ka sawdust, asbestos a i ʻole Taoshi, a laila kaomi ʻia i loko o kahi ʻōpala i ka wela kiʻekiʻe.I waena o lākou, ʻo ka resin phenolic ka resin synthetic mua i ka honua.
Phenolic plastic (bakelite): paʻakikī ka ʻili, palupalu a palupalu.He kani lāʻau ke kīkēkē.He opaque a ʻeleʻele ka nui (ʻeleʻele a ʻeleʻele paha).ʻAʻole palupalu i ka wai wela.He insulator ia, a ʻo kāna mea nui he resin phenolic.
