Pehea e koho ai i nā mea hoʻokaʻawale papa mika no ka hana commutator

ʻO ka papa mica commutator, i kapa ʻia ʻo ka commutator mica board, ʻo ia kekahi o nā mea insulating koʻikoʻi i nā motika DC. ʻElua mau mea nui no ka hana ʻana i ka papa mica commutator: ʻo ka pepa mica wahi liʻiliʻi, a ʻo ka pepa mica pauka. I mea e hiki ai i ka huahana ke hiki i ka mānoanoa i makemake ʻia, pono e wili ʻia ka pā mika i hana ʻia me nā pepa mika. I ke kaomi ʻana, hoʻopaʻa ʻia nā ʻaoʻao ʻelua me ka pepa liner a me ke kāwele like ʻole, i ʻano like ka mānoanoa a loaʻa ka paʻa o loko ma hope o ke kaomi ʻana. Ke hoʻohana ʻia ka pepa mika pauka no ka hana ʻana i ka papa mica pauda, ​​inā maikaʻi ke kūlana paʻi, hiki ke haʻalele ʻia ka hana wili a wili paha.

Eia kekahi, e like me nā pae insulation ʻokoʻa o ka kaʻa, a me nā koi o ka anti-arc a me ka pale ʻana i ka wai, shellac, polyester paint, melamine polyacid paint, ammonium phosphate aqueous solution, cyclic resin glue a i hoʻololi ʻia ka pena silicone i hoʻohana ʻia e like me nā mea hoʻopili. hana i nā ʻano ʻano papa mika.

Hiki i ka hoʻohana ʻana i ka shellac ke hana i nā papa mika commutator hiki ke piʻi i kahi mahana o 100 ° C a ʻoi aku ka kiʻekiʻe, me nā papa kapua commutator no nā kaʻa kaʻa kiʻekiʻe. Akā ʻo ka hemahema ʻo ia ka haʻahaʻa o ka hana hana.

ʻOi aku ka maikaʻi ma mua o ka shellac e hoʻohana i ka polyacid resin condensed mai ortho-jasmonic anhydride a me glycerin. He mea maʻalahi ke ʻili a hoʻopaʻa i nā pepa mika, a hiki iā ia ke hoʻomaʻamaʻa i ke kaʻina hana o ka hoʻopili ʻana i nā ʻāpana mika, i hiki i ka nui o nā konohiki ke hana i nā papa mika commutator. . Eia naʻe, ʻo ka hemahema ʻo ia ka resin unpolymerized i loko o ka papa mika, a ua hoʻoikaika ʻia ka depolymerization o ka resin i ka papa mica ma lalo o ka mana o ka wela kiʻekiʻe a me ke kaomi kiʻekiʻe. i ka ili o ka mea hoʻokele kaʻa.

I ka hoʻohana ʻana i ka polyacid resin commutator mica plate e like me ke kaʻa wela wela e hoʻokaʻawale i ka commutator o ka traction crane a i ʻole ka motika nui, pono ia e wela ma mua o ka hoʻohana ʻana. Ma hope o ka hana ʻana, i ke kaomi ʻana i ka commutator, e hoʻemi ʻia ka puka ʻana o ka resin, kahi e hōʻoia ai i ka hilinaʻi o ka commutator i ka hana.

ʻO ka hoʻohana ʻana i ka pauka Anfu e like me ka mea hoʻopili hiki ke hoʻololi i ka hana o ka commutator mica board ma lalo o nā kūlana o ka haʻahaʻa kiʻekiʻe a me ka mahana (200 ℃ a i ʻole). ʻOi aku ka liʻiliʻi o kona shrinkage ma mua o nā papa mika ʻē aʻe, a ʻoi aku kona kūpaʻa kiʻekiʻe ma mua o 600 ℃. No laila, ʻoi aku ka kiʻekiʻe o kona ʻano ma mua o nā papa mika like ʻole i ʻōlelo ʻia ma luna, a ʻoi aku ka laulā o ka noi.

ʻO ka papa mika i hana ʻia me ka epoxy a me ka melamine a me ka polyacid resin he kūpaʻa arc maikaʻi a hoʻohana ʻia i nā motika DC kiʻekiʻe.

Hiki i ka papa mica i hana ʻia me ka resin organik i hoʻololi ʻia ke kū i ka wela kiʻekiʻe a hoʻohana ʻia i nā mīkini kahe kūikawā.

Hāʻawi ʻo NIDE i nā papa mika like ʻole a me nā commutators, i hoʻohana nui ʻia ma ke kahua o nā mea hana mana, nā mīkini brushless, nā kaʻa kaʻa hou, nā mea pono hale, nā papa hāpai, nā moena lāʻau lapaʻau a me nā kula ʻē aʻe.
