ʻO ka electroplating ke kaʻina hana o ka hoʻohana ʻana i ka electrolysis e waiho i ka metala a i ʻole nā mea hao ma ka ʻili o ka mea hana e hana i kahi ʻāpana metala paʻa, paʻa a paʻa maikaʻi. ʻO ka electroplating o nā huahana plastik ka mea e hoʻohana ai:
L) pale ʻino
L) hoʻonani pale
L) ʻaʻahu kūʻē
L waiwai uila: hāʻawi i ka conductive a i ʻole insulating coatings e like me nā koi hana o nā ʻāpana
ʻO ka hoʻoheheʻe ʻana i ka alumini ka mea e wela a hoʻoheheʻe i ka metala alumini a hiki i ka hoʻoheheʻe ʻana ma lalo o ka momi, a ʻo nā ʻātoma alumini e hoʻoheheʻe ʻia ma ka ʻili o nā mea polymer e hana i kahi ʻāpana alumini lahilahi loa. Hoʻohana nui ʻia ka aluminizing vacuum o nā ʻāpana injection i ke kula o nā kukui automotive.
Nā koi no ka substrate aluminized vacuum
(1) He laumania ka ili o ka mea kumu, palahalaha a like me ka manoanoa.
(2) He kūpono ka ʻoʻoleʻa a me ka hoʻopili ʻana.
(3) ʻOi aku ka nui o ka ʻili ma mua o 38dyn / cm '.
(4) Loaʻa iā ia ka hana wela maikaʻi a hiki ke kūpaʻa i ka radiation wela a me ka wela condensation o ke kumu evaporation.
(5) ʻO ka maʻamau o ka substrate ma lalo o 0.1%.
(6) ʻO nā thermoplastics maʻamau o ka substrate aluminized he polyester (PET), polypropylene (PP), polyamide (n), polyethylene (PE), polyvinyl chloride (PVC), PC, PC / ABS, Pei, thermosetting material BMC, etc. .
ʻO ke kumu o ka hoʻopaʻa ʻana i ka vacuum:
1. Hoʻonui i ka noʻonoʻo ʻana:
Ma hope o ka uhi ʻia ʻana o ke kīʻaha reflective plastic me ka primer, ua uhi ʻia ia e waiho i kahi ʻāpana o ke kiʻi alumini ma luna o ka ʻili, i hiki ai i ke kīʻaha reflective ke hoʻokō a loaʻa i kekahi reflectivity.
2. nani nani:
Hiki i ke kiʻiʻoniʻoni aluminizing vacuum ke hana i nā ʻāpana i hoʻoheheʻe ʻia me ka waihoʻoluʻu hoʻokahi me ke ʻano metala a loaʻa ka hopena hoʻonaninani kiʻekiʻe.
