He aha nā mea hana hoʻokaʻawale maʻamau no nā lako uila hōʻoiaʻiʻo i ka pahū?

2021-05-31

  Wahi a nā mokuʻāina ʻokoʻa, hiki ke hoʻokaʻawale ʻia nā mea insulating o ka uila pahū-hōʻoia i nā mea insulating paʻa a me nā mea insulating wai. Pili wale kēia hoʻokaʻawale ʻana i nā mea uila pahū.

Mea hoʻokaʻawale paʻa

  ʻO ka mea hoʻopololei paʻa he mea hoʻopololei nona nā mea i loko o kahi kūlana paʻa i ka hoʻohana maoli. He wai kekahi mau mea i ka wā e hoʻolako ʻia ai a lilo i paʻa ma hope o ka hoʻohana ʻana. Manaʻo ʻia lākou he mau mea insulating paʻa.


  Hōʻike ka papa ma lalo nei i nā ʻano mea hoʻokalakupua paʻa i hoʻohana mau ʻia i nā mea uila pahū

Papa waiwai

Phenolic plastic


E like me nā māka o nā mea insulating paʻa i hoʻohana mau ʻia i nā mea uila pahū-hōʻoia i helu ʻia ma ka papa ʻaina, loiloi ʻia lākou e like me kā lākou comparative tracking index (CTI). ʻOiai ʻo kēia papa ka hana uila wale nō ma luna o ka ʻili, ʻokoʻa kona mau ʻano mechanical, pale wela, a me ke kūpaʻa kemika. No laila, i ka wā e koho ai nā kānaka i kēia mea, pono lākou e noʻonoʻo i kona mau ʻano mechanical, ka pale ʻana i ka wela, a me ke kūpaʻa kemika e like me nā kūlana kikoʻī o kona hoʻohana ʻana.

Mea hoʻoheheʻe (glazed).

  ʻO ia kahi mea hoʻokalakupua ʻole metala, i hana ʻia e ka sintering o nā metala oxides a me nā pūhui metala ʻole o ka oxygen. ʻO kona paʻakikī ma waena o 1000-5000HV; ʻO ka ikaika tensile ma waena o 26-36MPa; ka ikaika compressive ma waena o 460-680MPa; ʻoi aku ka helu hoʻoheheʻe ma luna o 2000 ℃; liʻiliʻi ka helu hoʻonui wela; kiʻekiʻe kemika paʻa, corrosion kū'ē, etc.

Mea hoʻoheheʻe palaki

  Melamine formaldehyde resin (MF)

  He plastic thermosetting me ka melamine formaldehyde resin ma ke ʻano he kumu kumu, cellulose ma ke ʻano he mea kōkua, a me nā mea hoʻohui like ʻole. Loaʻa iā ia ke kūpaʻa arc maikaʻi a me ka hoʻopau ʻana iā ia iho ma hope o ka puhi ʻana, akā he haʻahaʻa haʻahaʻa haʻahaʻa a me ka paʻa ʻole o ka dimensional. He kūpono ia no ka hana ʻana i nā ʻāpana insulating o nā lako uila.

Epoxy resin (EP)

  He plastic thermosetting composite me ka resin epoxy e like me ka mea nui a me nā mea hoʻohui ʻē aʻe e like me nā mea kōkua. ʻO kēia mea e like me FR4 pepa a 3240 papa epoxy loaʻa ka hana insulation maikaʻi, ka hana mechanical maikaʻi, ka hana hoʻopaʻa maikaʻi, ke kū'ē i ka wai kai (ka wai paʻakai), a me ka liʻiliʻi liʻiliʻi. He kūpono ia no ka hana ʻana i nā ʻāpana insulation uila a me nā papa kaapuni paʻi.

Phenolic Plastic (PF)

  He plastic thermosetting, me ka resin phenol ka mea nui, a me nā mea hoʻohui ʻē aʻe e like me nā mea kōkua. No ka laʻana, i ka wā o ka mea he aniani fiber, ua kapa ʻia ka huahana phenolic glass fiber reinforced plastic, nona ka ikaika kiʻekiʻe, ke kūpaʻa wela kiʻekiʻe a me ke kūpaʻa corrosion; inā he palaoa lāʻau ka mea, kapa ʻia ka huahana bakelite, e like me 3026 Phenolic pulupulu lole Laminated Pepa a papa pepa phenolic, nona nā waiwai mechanical a me nā waiwai insulation.

Acrylonitrile-butadiene-styrene copolymer (ABS)

  ʻO ia kahi mea ʻenehana thermoplastic maikaʻi loa. Ma muli o kāna mau waiwai mechanical maikaʻi, nā waiwai insulation, ka wela wela, ka corrosion resistance, a me ka maikaʻi o ka hopena hopena a me ka dimensional stability o nā ʻāpana i hoʻoheheʻe ʻia, hoʻohana nui ʻia ia i ka hana ʻana i nā ʻāpana a me nā ʻāpana insulation no nā lako like ʻole, e like me nā mea kūikawā. nā ʻāpana pahū e like me ka pahu pākaukau o ka pākaukau (Exs-U).

Kahelani (PE)

  Hoʻopili ʻia kēia thermoplastic e ka ethylene a ua māhele pinepine ʻia i ka polyethylene low density (LDPE) a me ka polyethylene high density (HDPE).


  ʻO ka polyethylene haʻahaʻa haʻahaʻa (LDPE) he palupalu maikaʻi, ductility a me ke aniani, a he kūpono ia no ka hana ʻana i nā ʻano kiʻi ʻoniʻoni plastik, e like me ma waena o nā electrodes maikaʻi a maikaʻi ʻole o ka pā; ʻoi aku ka maikaʻi o ka polyethylene kiʻekiʻe (HDPE) ʻO kona mau mea mechanical a me ka laulā hana ākea e kūpono no ka hana ʻana i nā ʻano paipu like ʻole, e like me nā pā uila liʻiliʻi, nā pahu pahu pahu pahu pahu pahu kūikawā kūikawā (Exs-U), etc.


  ʻO LDPE a i ʻole HDPE paha, loaʻa iā lākou nā waiwai hoʻokaʻawale uila maikaʻi a ua hoʻohana maikaʻi ʻia i ka hana ʻana i nā lako uila pahū.
