ʻO ka ʻaila hoʻokaʻawale varnish, i ʻike ʻia hoʻi he pena hoʻokaʻawale a i ʻole varnish, he hana ia i ka hoʻokaʻawale ʻana, ke kūpaʻa ʻana i ka makū, ka hoʻopuehu ʻana i ka wela, a me ka hoʻōla ʻana i nā mea hoʻololi alapine kiʻekiʻe.
Wahi a kā lākou mau ʻano kemika like ʻole, hiki ke hoʻokaʻawale ʻia nā aila insulating i ʻekolu mau māhele: polyester based; Resin class; Siliceous materials. Hoʻomākaukau nui ʻia ka aila insulating polyester e ka hopena condensation o polyols a me polyacids, a he wai aniani ʻole a melemele māmā paha. Loaʻa iā ia kahi voltage breakdown kiʻekiʻe a me ka resistivity volume, hiki ke pale pono i ke kahe ʻana o ke au a hāʻawi i ka insulation maikaʻi. Loaʻa iā ia ka uku kūpono kiʻekiʻe loa ma waena o nā ʻano ʻekolu o nā aila insulation a ʻo ia ka aila insulation i hoʻohana pinepine ʻia i nā transformers alapine kiʻekiʻe.
Eia nō naʻe, he kiʻekiʻe ka mānoanoa o ka ʻaila insulating polyester, a ua hoʻopilikia nui ʻia kona mānoanoa e ka mahana. Hoʻonui nui ʻia ka mānoanoa i nā mahana haʻahaʻa, kahi e hoʻopilikia nui ai i kona kahe a me ka hopena hoʻopuehu wela. No laila, i ka wā e hoʻohana ʻia ai, pono pinepine e hoʻohui i nā mea hoʻoheheʻe e hōʻemi i ka mānoanoa o ka ʻaila insulating, mālama i ka maikaʻi o ka wai, a hōʻoia i ka hiki ke hoʻokomo piha ʻia ka mea hoʻololi alapine kiʻekiʻe i ka wā e hoʻokomo ʻia ai. ʻO ke kaumaha kikoʻī o ka ʻaila insulating polyester a me ka mea hoʻoheheʻe ma kahi o 0.9, hiki ke hoʻāʻo ʻia e kahi mika kaumaha kikoʻī.
ʻO ka lua, he maʻalahi ka ʻaila insulating polyester i ka oxidation a me ka degradation i nā mahana kiʻekiʻe, e hana ana i nā mea acidic a me ka sludge, kahi e hoʻopilikia ai i ka hana maʻamau o ka huahana a kaupalena i kona laulā o ka hoʻohana ʻana i nā wahi wela kiʻekiʻe. Eia kekahi, i hoʻohālikelike ʻia me nā aila insulating resin a me siliceous, ʻoi aku ka kiʻekiʻe o nā waiwai tangent dielectric loss o nā aila insulating polyester, ʻo ia hoʻi, ʻoi aku ka nui o ka pohō ikehu ma lalo o nā kahua uila alternating a e hoʻopilikia i kekahi ʻano i ka pono hana o ka huahana.
I kēia manawa, hoʻohana pinepine ʻia ka ʻaila insulating polyester no ka hoʻopili ʻana i nā wili, e like me nā mea hoʻololi alapine kiʻekiʻe, nā motika, nā kaula, a me nā mea ʻē aʻe, hiki ke hoʻomaikaʻi i ka insulation, ka conductivity thermal, a me ke kūpaʻa ʻana o ka makū o nā huahana a hoʻolōʻihi i ko lākou ola lawelawe. ʻO ka ʻaila insulating i hoʻokumu ʻia i ka resin ua hana nui ʻia me nā hui polymer organik, pinepine i ke ʻano wai a paʻa paha, me ke kūpaʻa maikaʻi o ka ʻaʻahu.
Hiki ke hoʻohuihui ʻia nā aila hoʻokaʻawale i hoʻokumu ʻia me ka resin ma ka hoʻoponopono ʻana i ka hapa o nā mea maka a me nā kūlana hopena e hana i nā wai resin me ka viscosity haʻahaʻa. Loaʻa i kēia mau wai ka wai maikaʻi a me nā waiwai uhi, a ʻaʻole pono nā mea hoʻoheheʻe hou aʻe. Ma lalo o nā kūlana hoʻomehana, hiki i ka aila hoʻokaʻawale i hoʻokumu ʻia me ka resin ke palupalu a hoʻoheheʻe paha. Ke hoʻohālikelike ʻia me ka aila hoʻokaʻawale polyester, ʻoi aku ka paʻa o ka aila hoʻokaʻawale resin, ʻoi aku ka maikaʻi o ka hana hoʻokaʻawale uila, a ʻoi aku ke kumukūʻai. Hoʻohana pinepine ʻia no ka hoʻokaʻawale ʻana o nā mea hoʻololi like ʻole, nā kikowaena uila, a me nā hui. ʻO ka aila hoʻokaʻawale siliceous ka mea nui i hana ʻia me nā hui silicon organik e like me polydimethylsiloxane. ʻO ka maʻamau he wai aniani ʻole a melemele māmā paha me ka viscosity haʻahaʻa loa a me ka wai maikaʻi.
I ka hoʻohālikelike ʻia me nā aila insulating polyester a me ka resin, ʻoi aku ka haʻahaʻa o nā waiwai pohō dielectric o nā aila insulating siliceous, ʻoi aku ka liʻiliʻi o ka pohō ikehu ma lalo o nā kahua uila alternating, a ʻoi aku ka kiʻekiʻe o ka pono hana huahana. Loaʻa iā ia ke kūpaʻa arc maikaʻi a me ke kūpaʻa leakage, a hiki ke mālama i ka hana paʻa i nā wahi koʻikoʻi. Hiki ke hoʻohana ʻia ka aila insulating siliceous no ka insulation ma nā wahi koʻikoʻi e like me ke voltage kiʻekiʻe, ke mahana kiʻekiʻe, ka haʻahaʻa kiʻekiʻe, a me ke anu nui, e hoʻomaikaʻi ana i ka pae insulation a me ka hilinaʻi hana o nā huahana. ʻO kona kiko hoʻā ahi kiʻekiʻe a me nā waiwai kinai ponoʻī e hāʻawi i nā aila insulating siliceous i nā pono koʻikoʻi i ka palekana ahi. Eia nō naʻe, ʻoi aku ke kumukūʻai o ka aila insulating siliceous a ʻaʻole hoʻohana pinepine ʻia i nā mea hoʻololi alapine kiʻekiʻe.
