ʻO nā waiwai o nā microspheres aniani ʻeleʻele a me kā lākou mau ʻano plastik pili

Nā microspheres aniani hāmamaʻO nā microspheres aniani i hoʻomaʻamaʻa kūikawā ʻia, i ʻike nui ʻia e ka haʻahaʻa haʻahaʻa a ʻoi aku ka maikaʻi o ka conductivity thermal ma mua o nā microspheres aniani.He ʻano hou ia o nā mea māmā micron-scale i hoʻomohala ʻia i nā makahiki 1950 a me 1960.ʻO kāna mea nui he borosilicate, me ka nui o ka nui o 10 ~ 250μm a me ka mānoanoa pā o 1 ~ 2μm;Ua loaʻa nā hiʻohiʻona o ka ikaika compressive kiʻekiʻe, kiʻekiʻe heheʻe, kiʻekiʻe resistivity, a me ka liʻiliʻi thermal conductivity a me ka thermal shrinkage coefficient.Ua ʻike ʻia ʻo ia ʻo ka "space age material" i ke kenekulia 21.Nā microspheres aniani hāmamaloaʻa i ka hoʻohaʻahaʻa kaumaha a me ke kani ʻana a me nā hopena insulation thermal, i loaʻa i nā huahana i ka hana anti-cracking maikaʻi a me ka hana hou ʻana, a ua hoʻohana nui ʻia i nā mea i hoʻohui ʻia e like me ke aniani fiber reinforced plastic, artificial marble, artificial agate, a me ka ka ʻoihana ʻaila, ʻoihana aerospace a me nā ʻoihana aerospace., nā kaʻaahi kiʻekiʻe kiʻekiʻe hou, nā kaʻa a me nā moku, nā mea hoʻoheheʻe wela a me nā kula ʻē aʻe i hoʻoikaika maikaʻi i ka hoʻomohala ʻana i nā hana ʻepekema a me ka ʻenehana o koʻu ʻāina.I mea e hoʻokō ai i nā koi o ka dielectric haʻahaʻa, haʻahaʻa haʻahaʻa a me ke kaumaha māmā o nā mea kamaʻilio 5G, ʻoi aku ka nui o nā microspheres aniani hollow ma muli o kā lākou kumukūʻai haʻahaʻa a me ka hana maikaʻi.

1 - Mea hoʻohui

ʻO ka haku mele ʻana o nā microspheres aniani ʻeleʻele (mass ratio)

SiO2: 50% -90%, Al2O3: 10% -50%, K2O: 5% -10%, CaO: 1% -10%, B2O3: 0-12%

2- Nā hiʻohiʻona

kala keʻokeʻo maʻemaʻe

Hiki ke hoʻohana nui ʻia i nā huahana i loaʻa nā koi i ka helehelena a me ke kala.

3- māmā māmā

ʻO ka mānoanoa o nā microspheres aniani hāmama ma kahi o hoʻokahi hapaʻumi o ka mānoanoa o nā ʻāpana hoʻopiha kuʻuna.Ma hope o ka hoʻopiha ʻana, hiki ke hoʻemi nui ʻia ke kaumaha kumu o ka huahana, hiki ke hoʻololi a mālama ʻia nā resins hana hou aku, a hiki ke hoʻemi ʻia ke kumukūʻai huahana.

4-Lipophility

He mea maʻalahi ka hoʻomaʻemaʻe a hoʻopuehu ʻia nā microspheres aniani hollow, a hiki ke hoʻopiha ʻia i ka nui o nā thermoplastic resins thermosetting, e like me ka polyester, epoxy resin, polyurethane, etc.

5-Maikaʻi ka wai

No ka mea he mau ʻāpana liʻiliʻi nā microspheres aniani, ʻoi aku ka maikaʻi o ka wai i loko o nā resins wai ma mua o ka flake, ka nila a i ʻole nā ​​​​mea hoʻopiha ʻole, no laila ua maikaʻi loa lākou i ka hoʻopiha piha ʻana.ʻO ka mea nui aku, he isotropic nā microbeads liʻiliʻi, no laila ʻaʻohe hemahema o ka hoʻohaʻahaʻa ʻole ʻana i nā ʻāpana like ʻole ma muli o ka orientation, e hōʻoiaʻiʻo ana i ka paʻa o ka huahana a ʻaʻole e warp.

6- Ka wela a me ke kani ʻana i ka hoʻoheheʻe ʻana

ʻO ka loko o nā microspheres aniani ʻeleʻele he kinoea lahilahi, no laila aia nā hiʻohiʻona o ka insulation leo a me ka insulation wela, a he mea hoʻopihapiha maikaʻi loa ia no nā ʻano mea hoʻoheheʻe wela a me nā huahana insulation kani.Hiki ke hoʻohana ʻia nā waiwai insulating o nā microspheres aniani hollow no ka pale ʻana i nā huahana mai ka haʻalulu wela i hana ʻia e ka hoʻololi ʻana ma waena o ka hoʻomehana wikiwiki a me nā kūlana hoʻomaha wikiwiki.ʻO ke kūpaʻa kikoʻī kiʻekiʻe a me ka haʻahaʻa haʻahaʻa haʻahaʻa o ka wai e hoʻohana nui ʻia i ka hana ʻana i nā mea hoʻoheheʻe uwea.

7- Haʻahaʻa aila absorption

Hoʻoholo nā ʻāpana o ka pōʻai nona ka liʻiliʻi liʻiliʻi kikoʻī kikoʻī kikoʻī a me ka haʻahaʻa o ka ʻaila absorption rate.I ka wā o ka hoʻohana ʻana, hiki ke hoʻemi nui ʻia ka nui o ka resin, a ʻaʻole e hoʻonui nui ka viscosity ma lalo o ka manaʻo o ka nui hoʻohui kiʻekiʻe, kahi e hoʻomaikaʻi nui ai i nā kūlana hana a me ka hana.E hoʻonui i ka pono hana ma 10% a 20%.

8- Haʻahaʻa dielectric mau

ʻO ka waiwai Dk o nā microspheres aniani hollow he 1.2 ~ 2.2 (100MHz), hiki ke hoʻomaikaʻi maikaʻi i nā waiwai dielectric o ka mea.

ʻO nā plastik no nā lei aniani ʻaʻa

(1) No ka hoʻololi ʻana i nā plastics ʻenekinia e like me nylon, PP, PBT, PC, POM, a me nā mea ʻē aʻe, hiki ke hoʻomaikaʻi i ka fluidity, hoʻopau i ka ʻike aniani fiber, lanakila i ka warpage, hoʻomaikaʻi i ka hana pale ahi, hoʻemi i ka hoʻohana ʻana i ke aniani fiber, a hoʻemi i ka hana. koina.

(2) ʻO ka hoʻopiha ʻana me ka PVC paʻa, PP, PE, a me ka hana ʻana i nā mea profiled, nā paipu a me nā papa e hiki ai i nā huahana ke loaʻa i ke kūpaʻa dimensional maikaʻi, hoʻomaikaʻi i ka rigidity a me ka mahana pale wela, hoʻomaikaʻi i ka hana kumukūʻai o nā huahana, hoʻomaikaʻi i ka hana pono a hoʻemi i nā kumukūʻai.

(3) ʻO ka hoʻopiha ʻana i ka PVC, PE a me nā kaula ʻē aʻe a me nā mea insulating sheath e hiki ke hoʻomaikaʻi i ke kūpaʻa wela kiʻekiʻe o ka huahana, insulation, acid and alkali resistance a me nā waiwai ʻē aʻe a me ka hana hoʻoponopono huahana, hoʻonui i ka huahana a hoʻemi i nā kumukūʻai.

(4) ʻO ka hoʻopiha ʻana i ka pā epoxy resin copper clad plate hiki ke hōʻemi i ka viscosity o ka resin, hoʻonui i ka ikaika kulou, hoʻomaikaʻi i kona ʻano kino a me ka mechanical, hoʻonui i ka mahana hoʻololi aniani, hoʻemi i ka dielectric mau, hoʻemi i ka lawe ʻana o ka wai, a hoʻemi i ke kumukūʻai. .

(5) ʻO ka hoʻopiha ʻana me ka polyester unsaturated hiki ke hōʻemi i ka nui o ka shrinkage a me ka holoi ʻana i ka wai o ka huahana, hoʻomaikaʻi i ka pale ʻana a me ka paʻakikī, a he liʻiliʻi nā lua i ka wā o ka lamination a me ka uhi.Hoʻohana ʻia ia no nā huahana FRP, nā huila polishing, nā mea hana, etc.

(6) Hiki i ka hoʻopiha ʻana me ka resin silicone ke hoʻomaikaʻi i nā waiwai kino a me ka mīkini, a hiki i ka nui o ka hoʻopiha piha ʻana ke hoʻemi nui i ke kumukūʻai, ʻo ia kahi mea kūpono no ka hana ʻana i nā mold.
