By Mike Chen, Luna Hoʻokele Hana | 12+ Makahiki ma ka Hana ʻana i ka Laho |LinkedIn

Nā Manaʻo Koʻikoʻi

• Pono ka laholio silicone i hoʻohana ʻia i nā mea uila i nā ʻae ʻana i loko o ±0.1 mm no nā gaskets a me nā sila a me ka hoʻokō ʻana i ka lapalapa ahi UL 94 V-0 no nā ʻāpana uila kūloko.
• Hoʻokō nā mīkini ʻoki silicone kikoʻī me ka mana motika servo i ka pololei o ka hānai ʻana o ±0.1 mm ma nā wikiwiki ʻokiʻoki a hiki i 120 pahi i kēlā me kēia minuke no ka hana ʻana i nā ʻāpana uila.
• ʻO ka ikaika haʻahaʻa o ka silicone e paʻakikī ai ka hoʻohemo ʻana i ka mīkini; ʻo ka hoʻohemo ʻana i ka cryogenic ma -100°C a i -130°C ke ʻano makemake ʻia no nā ʻāpana uila silicone me ka ʻālohilohi lahilahi ma lalo o 0.3 mm.
• Hoʻopau nā kaʻina hana hoʻomaʻemaʻe a hoʻomaloʻo ʻekolu pae i nā mea hoʻokuʻu ʻōpala a me ka haumia particulate ma mua o ka hoʻomau ʻana o nā ʻāpana uila silicone i ka hōʻuluʻulu ʻana a i ʻole ka hoʻopili ʻana.

ʻO ka pane pōkole:ʻO ka hana ʻana i ka laholio silicone no ka ʻoihana uila e pili ana i ka ʻoki pololei ʻana o nā pepa silicone i loko o nā gaskets a me nā sila, ka wehe ʻana i nā ʻāpana uila silicone i hoʻoheheʻe ʻia, ka hoʻomaʻemaʻe e wehe i nā mea hoʻokuʻu mold a me ka haumia particulate, a me ka hoʻōla ʻana i kāohi ʻia e hoʻokō i nā waiwai kino i kuhikuhi ʻia. No ka mea, pono nā pā uila a me nā ʻāpana sila i nā ʻae ʻana o ka dimensional i loko o ± 0.1 mm a me ka maʻemaʻe o ka ʻili i kūpono no nā wahi lumi maʻemaʻe, ʻo nā lako hana hana automated me ka mana motor servo, ka papahana PLC, a me nā ʻōnaehana hoʻomaʻemaʻe multi-stage he mea maʻamau i ka hana silicone papa uila.

Ua kuhikuhi ʻia ka laholio silicone i loko o nā mea uila no kona kūpaʻa wela, nā waiwai insulation uila, a me ke kū'ē ʻana i ka hōʻino ʻana o ke kaiapuni. ʻO nā noi koʻikoʻi e pili ana i nā membrane keypad, nā sila hoʻohui, nā gasket EMI, nā gasket bezel hōʻike, nā sila ʻāpana pākahiko, a me nā kāmaʻa pale no nā kuapo a me nā sensor. Hoʻokau kēlā me kēia noi i nā koi hana kikoʻī e ʻokoʻa mai ka hoʻoheheʻe silicone kumu maʻamau ma muli o nā hoʻomanawanui paʻa a me nā kūlana maʻemaʻe i koi ʻia e ka ʻākoakoa uila.

No ka mea, he mahana hoʻololi aniani ko ka silicone rubber kokoke i -120°C a hōʻike i ka ikaika haehae haʻahaʻa i hoʻohālikelike ʻia me nā elastomers ʻē aʻe, pono nā lako a me nā palena i hoʻopilikino ʻia no kēia mau ʻano kino i kāna hana ʻana. Uhi kēia ʻatikala i nā pae hana nui - ʻoki ʻana, deflashing, hoʻomaʻemaʻe, a me ka hōʻoia ʻana i ka maikaʻi - no nā ʻāpana silicone rubber i hoʻohana ʻia i nā huahana uila.

Nā noi ʻana o ka Silicone Rubber i nā mea uila: Nā koi hana

ʻO nā ʻāpana laholio silicone i loko o nā huahana uila e hāʻule i ʻekolu mau māhele e like me ka paʻakikī o ka hana ʻana. ʻO nā Gaskets a me nā sila he ʻoki make-ʻoki a honi-ʻoki paha mai nā pepa silicone i kalena ʻia me nā mānoanoa mai 0.5 mm a 5.0 mm. No kēlā me kēiaASTM D2000Ma ke ʻano he hoʻokaʻawale no nā huahana laholio, ua kuhikuhi pinepine ʻia nā gaskets silicone no nā mea uila ma lalo o nā callouts laina e like me 2GE705 me nā koi paʻakikī, tensile, a me ka elongation e pili ana i ka noi.

Hana ʻia nā ʻāpana silicone i hoʻoheheʻe ʻia - nā keypads, nā kāmaʻa puki, a me nā pā maʻamau - ma o ka hoʻoheheʻe ʻana i ka compression a i ʻole ka wai silicone rubber (LSR). Pono kēia mau ʻāpana e wehe i ka flash ma hope o ka hoʻoheheʻe ʻana, a ʻo ka flash lahilahi maʻamau o ka hoʻoheheʻe ʻana o LSR e pono ai ka cryogenic a i ʻole ka mechanical deflashing. ʻO ke kolu o ka mahele, nā silicone encapsulants a me nā potting compounds, ua hoʻopili ʻia ma ke ʻano he wai a hoʻōla ʻia ma kahi me ka ʻole o ka hana mechanical.

Ua kuhikuhi ʻia ʻo UL 94 a me IEC 60068 no nā koi pale ahi a me nā hoʻāʻo ʻana i ke kaiapuni i nā noi uila.

ʻOki ʻana i ka Silicone Precision no nā ʻāpana uila

ʻO kamīkini ʻoki siliconemai Xiamen Xingchangjia ua hoʻolālā ʻia e hana i nā pepa silicone a me nā ʻōwili i nā ana kikoʻī e pono ai no nā gaskets uila a me nā sila. ʻO ka mīkini servo drive a me ka mana pā PLC e hiki ai i nā ʻano ʻokiʻoki hiki ke hoʻonohonoho ʻia me ka hohonu hiki ke hoʻololi ʻia a me ke koho ʻana o ka pahi, ka lawelawe ʻana i nā pepa silicone, nā paipu, a me nā ʻano maʻamau.

No ka hana ʻana i nā ʻāpana silicone uila me ka nui o ka hana ʻana,mīkini ʻoki silicone piha pihaHāʻawi ka mīkini i ka hana mau me ka hoʻopili ʻakomi. ʻO nā kikoʻī koʻikoʻi e pili ana i ka laulā ʻokiʻoki hiki ke hoʻololi ʻia mai ka ʻole a luna, ka lōʻihi o ka pahi o 550 mm, ka mānoanoa o ka ʻokiʻoki mai 0 a 10 mm, a me ka wikiwiki o ka ʻokiʻoki a hiki i 120 pahi i kēlā me kēia minuke. Hoʻohana ka mīkini i kahi cylinder pneumatic e kaomi i ka mea me ke kaomi i hoʻoponopono ʻakomi ʻia i ka mānoanoa o ka mea, e hoʻopau ana i ka hoʻoponopono puna lima i loaʻa ma nā lako kahiko. Nānā ka ʻōnaehana i kāohi ʻia e ka PLC i ka hānai mea, ka helu huahana, a me ka hoʻopili ʻana me nā alarm no ka hemahema o nā mea a me nā kūlana piha.

ʻO ka ʻoki ʻana i ka ʻoki ʻana - ʻo ka ʻoki ʻana ma o ka papa silicone akā ʻaʻole ka liner hoʻokuʻu - ke ʻano maʻamau no nā gaskets silicone i kākoʻo ʻia i hoʻohana ʻia i loko o nā pā uila. He mea koʻikoʻi ka pololei o ka hānai ʻana o ka mīkini servo o ±0.1 mm no ka mālama ʻana i ke kūlike o ka dimensional ma nā tausani o nā ʻāpana no kēlā me kēia pūʻulu.

Nā ʻāpana uila Silicone Rubber Deflashing

Hoʻokumu nā ʻano kino o ka Silicone i nā pilikia deflashing kūikawā. No ka mea he haʻahaʻa ka ikaika haehae o ka rubber silicone a me ke kūlou kiʻekiʻe, pelu ka flash mold lahilahi ma mua o ka haki ʻana ma lalo o ka abrasion mechanical. No nā ʻāpana uila silicone me ka mānoanoa o ka flash ma lalo o 0.3 mm, pilikia ka deflashing mechanical i ka haehae ʻana i ka mea kumu ma ka hui flash. ʻO ka deflashing cryogenic ma -100°C a i -130°C me ka hoʻohana ʻana i ka naikokene wai e ʻoki koho i ka flash lahilahi me ka mālama ʻana i ke kūpaʻa o ke kino silicone, e hiki ai ke wehe i ka flash maʻemaʻe me ka ʻole o ka hōʻino ʻana o ka ʻili.

No nā ʻāpana silicone me ka ʻālohilohi mānoanoa ma luna o 0.3 mm a i ʻole nā ​​geometries laina mahele maʻalahi, hiki ke hoʻohana ʻia ka deflashing mechanical me nā media palupalu a me ka wikiwiki hiolo i hoʻemi ʻia. ʻO kaMīkini hoʻopau ʻūlū mīkini XCJ-G600hana i nā ʻāpana silicone i loko o kona pae anawaena 3 mm a 100 mm ke hoʻoponopono ʻia me nā palena kūpono, ʻoiai ua ʻōlelo ʻia nā ʻāpana hoʻāʻo e hōʻoia i ka maikaʻi o ka ʻili ma mua o ka hana piha ʻana.

Hoʻomaʻemaʻe a hoʻomaloʻo i nā ʻāpana Silicone no ka ʻākoakoa uila

Pono nā ʻāpana uila silicone e hoʻomaʻemaʻe ma hope o ke kāwili ʻana a me ka deflashing e wehe i nā mea hoʻokuʻu mold, ka lepo flash koena, a me ka lawelawe ʻana i nā mea haumia. Hiki i nā mea hoʻokuʻu mold ke hoʻopilikia i ka hoʻopili ʻana i ka wā o ka ʻākoakoa uila, a hiki i ka haumia particulate conductive ke hana i nā kaapuni pōkole i nā mea i hōʻuluʻulu ʻia.mīkini hoʻomaʻemaʻe a hoʻomaloʻo laholioua hoʻolālā kūikawā ʻia no ka ʻōpala silicone, nā lako, nā plastics, a me nā pā uila, me ka hoʻohana ʻana i ʻekolu mau pūʻulu o nā kaʻina hana hoʻomaʻemaʻe ʻeono-pae e hiki ke hui pū ʻia no nā pae haumia like ʻole.

No nā noi uila e koi ana i ka hoʻohālikelike ʻana o ka lumi maʻemaʻe, pono ke kaʻina hana hoʻomaʻemaʻe e hoʻohana i ka wai deionized a me nā surfactants non-ionic i ukali ʻia e ka hoʻomaloʻo ʻana i kānana ʻia e HEPA e pale aku i ka haumia hou ʻana. ʻO nā pae hoʻomaʻemaʻe ʻeono o ka mīkini e ʻae i ka holoi ʻana, ka holoi ʻana, a me nā pōʻaiapuni maloʻo i hiki ke hoʻolālā ʻia no nā ʻano silicone kikoʻī. No kēlā me kēiaIPC-1601nā kūlana lawelawe no nā ʻākoakoa uila, pono e komo pū ka hōʻoia ʻana o ka maʻemaʻe me ka nānā ʻana i ka ʻike maka ma ka hoʻonui ʻana o 10x a me ka hoʻāʻo haumia ionic no nā ʻāpana e komo ana i nā ʻākoakoa uila hilinaʻi kiʻekiʻe.

Ka Mana Hoʻomalu Kūlana ma ka Hana ʻana i ka Silicone Rubber no nā Mea Uila

Nā palena maikaʻi e pili ana i nā kikoʻī maʻamau no nā ʻāpana silicone rubber i nā huahana uila mea kūʻai aku a me nā ʻoihana. ʻOkoʻa nā koi kikoʻī e ka OEM.

Pono ka nānā ʻana o nā ana o nā ʻāpana uila silicone e noʻonoʻo i ka coefficient hoʻonui wela o ka mea, ʻo ia hoʻi ma kahi o 3-4 mau manawa kiʻekiʻe ma mua o NBR a i ʻole EPDM. ʻO nā ʻāpana i ana ʻia ma 25°C hiki ke piʻi aʻe i ka 0.15% ʻoi aku ka nui ma mua o ka mahana kuhikuhi maʻamau 23°C i kuhikuhi ʻia ma ISO 3601 no ke ana ʻana o ke apo O. Manaʻo ʻia nā wahi nānā i kāohi ʻia e ka mahana no nā ʻāpana uila silicone pololei.

Hopena: Ka Hana Hoʻohui no ka ʻĀpana Silicone Papa-Elektronika

Pono ka hana ʻana i ka laholio silicone no ka ʻoihana uila i ka pololei i kēlā me kēia pae - mai ka ʻoki ʻana a me ka deflashing a hiki i ka hoʻomaʻemaʻe ʻana a me ka hōʻoia ʻana i ka maikaʻi. ʻO ka ikaika haehae haʻahaʻa a me ka ʻike wela kiʻekiʻe o ka silicone e koi ana i nā ʻāpana lako hana ʻokoʻa mai nā mea i hoʻohana ʻia no nā hui NBR, EPDM, a i ʻole FKM. ʻO nā mīkini ʻokiʻoki aunoa me ka mana motor servo, ka deflashing cryogenic no nā ʻāpana silicone lahilahi, a me nā ʻōnaehana hoʻomaʻemaʻe multi-stage e hana i ka laina hana maʻamau no nā ʻāpana silicone papa uila.

Pono nā mea hana e komo ana i ka mākeke silicone uila e hōʻoia i kēlā me kēia pae hana me nā ʻāpana hoʻāʻo ma mua o ka hana piha ʻana, e uku pono ana i ke koho ʻana o ke ʻano deflashing e pili ana i ka mānoanoa o ka flash a me ka pono o ka hoʻomaʻemaʻe no ka wehe ʻana i ka ʻōpala.
