Nā mea hoʻopili ʻē aʻe UV-Curing Adhesives

Ke hoʻohana nui ʻia nei kahi hanauna hou o nā silicones UV-curing a me nā epoxies i nā noi automotive a me nā uila.
ʻO kēlā me kēia hana i ke ola e pili ana i kahi kālepa: ʻO ka loaʻa ʻana o kahi pōmaikaʻi ma ka lilo o kekahi, e hoʻokō pono ai i nā pono o ke kūlana i ka lima. Ke pili nei ke kūlana i ka hoʻopaʻa ʻana i ka nui, hoʻopaʻa ʻana a i ʻole gasketing, hilinaʻi nā mea hana i nā adhesives UV-cure no ka mea e ʻae lākou i ka hoʻōla wikiwiki ʻana (1 a 5 kekona ma hope o ka ʻike ʻana i ka māmā).

ʻO ka mea kūʻai aku, ʻo ia ka mea e pono ai kēia mau mea hoʻopili (acrylic, silicone a me epoxy) i kahi substrate māmā e hoʻopaʻa pono ai, a ʻoi aku ka nui o ke kumukūʻai ma mua o nā mea hoʻopili e hoʻōla ma nā ʻano ʻē aʻe. Eia nō naʻe, ua hauʻoli nā mea hana i nā ʻoihana he nui i kēia kālepa no nā makahiki he nui. Nui nā ʻoihana e hana pēlā no ka wā e hiki mai ana. ʻO ka ʻokoʻa, ʻo ia ka mea e hoʻohana ai nā ʻenekinia i kahi silicone a i ʻole epoxy UV-cure adhesive, e like me ka acrylic-based.

"ʻOiai ua hana mākou i nā silicones UV-cure no nā makahiki he ʻumi i hala iho nei, i nā makahiki ʻekolu i hala iho nei ua pono mākou e hoʻoikaika i kā mākou mau hana kūʻai aku e hoʻomau i ka noi mākeke," wahi a Doug McKinzie, hope pelekikena o nā huahana kūikawā ma Novagard Nā hoʻonā. "Ua hoʻonui kā mākou kūʻai silicone UV-cure i ka 50 pakeneka i nā makahiki i hala. E hōʻemi kēia i kekahi, akā ke manaʻo nei mākou i ka ulu maikaʻi no nā makahiki e hiki mai ana.

Ma waena o nā mea hoʻohana nui loa o nā silicones UV-cure he OEM automotive, a me nā mea hoʻolako Tier 1 a me Tier 2. Hoʻohana kekahi mea hoʻolako Tier 2 iā Loctite SI 5031 sealant mai Henkel Corp. i nā pahu ipu i loko o nā hale no nā modula hoʻokele uila uila a me nā mea ʻike puʻupuʻu. Hoʻohana pū ka ʻoihana iā Loctite SI 5039 e hana i kahi gasket silicone UV-cured-in-place a puni ka perimeter o kēlā me kēia module. Ua ʻōlelo ʻo Bill Brown, ka luna o ka ʻenekinia noi no Henkel, aia nā huahana ʻelua i ka wai kala e kōkua i ka hōʻoia ʻana i ke komo ʻana i ka wā o ka nānā hope ʻana.

Hoʻouna ʻia kēia subassembly i kahi mea hoʻolako Tier 1 e hoʻokomo i nā ʻāpana kūloko hou a hoʻopili i kahi PCB i nā hopena. Hoʻokomo ʻia kahi uhi ma luna o ka ʻāpana āpau e hana i kahi sila paʻa i ke kaiapuni ma ka hui hope.

Hoʻohana pinepine ʻia nā epoxy adhesives UV-cure no nā noi uila a me nā mea kūʻai aku. Hoʻokahi kumu, ʻo kēia mau mea hoʻopili, e like me nā silicones, ua hoʻonohonoho pono ʻia e kūlike i ka nalu o nā kumu kukui LED (320 a 550 nanometers), no laila e loaʻa i nā mea hana nā pono āpau o ke kukui LED, e like me ke ola lōʻihi, ka wela palena a me nā hoʻonohonoho maʻalahi. ʻO ke kumu ʻē aʻe ʻo ke kumukūʻai haʻahaʻa haʻahaʻa o ka curing UV, no laila e maʻalahi ai nā ʻoihana e kālepa i kēia ʻenehana.
