1 – Mea Hoʻohui
Ka hoʻohui kemika o nā microspheres aniani hakahaka (lakio nuipa)
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 āpau i loaʻa nā koi ma ke ʻano a me ke kala.
3- ka mānoanoa o ke kukui
ʻO ka nui o nā microspheres aniani hakahaka ma kahi o hoʻokahi hapaʻumi o ka nui o nā ʻāpana hoʻopihapiha 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 o ka huahana.
4-Lipophilicity
He maʻalahi ka hoʻomaʻū a me ka hoʻopuehu ʻana i nā microspheres aniani hakahaka, a hiki ke hoʻopiha ʻia i loko o ka hapa nui o nā resins thermoplastic thermosetting, e like me ka polyester, epoxy resin, polyurethane, a pēlā aku.
5-Ka waiwai maikaʻi
ʻOiai he mau poepoe liʻiliʻi nā microspheres aniani hakahaka, ʻoi aku ka maikaʻi o ko lākou kahe ʻana i loko o nā resins wai ma mua o ka flake, nila a i ʻole nā mea hoʻopihapiha maʻamau ʻole, no laila he hana hoʻopiha mold maikaʻi loa kā lākou. ʻOi aku ka mea nui, he isotropic nā microbeads liʻiliʻi, no laila ʻaʻohe hemahema o nā helu shrinkage kūlike ʻole ma nā ʻāpana like ʻole ma muli o ke kuhikuhi ʻana, kahi e hōʻoiaʻiʻo ai i ke kūpaʻa dimensional o ka huahana a ʻaʻole e warp.
6- Hoʻopaʻa wela a me ke kani
He kinoea lahilahi ka loko o nā microspheres aniani hakahaka, no laila he mau ʻano like ia o ka pale leo a me ka pale wela, a he mea hoʻopiha maikaʻi loa ia no nā huahana pale wela like ʻole a me nā huahana pale leo. Hiki ke hoʻohana ʻia nā waiwai pale o nā microspheres aniani hakahaka e pale i nā huahana mai ka haʻalulu wela i hoʻokumu ʻia e ka hoʻololi ʻana ma waena o nā kūlana hoʻomehana wikiwiki a me nā kūlana hoʻomaʻalili wikiwiki. ʻO ke kū'ē kikoʻī kiʻekiʻe a me ka omo wai haʻahaʻa loa e hoʻohana nui ʻia ai i ka hana ʻana i nā mea pale uwea.
7- Ka hoʻopili ʻana o ka ʻaila haʻahaʻa
ʻO nā ʻāpana o ka poepoe e hoʻoholo ai he liʻiliʻi loa kona wahi ʻili kikoʻī a me ka haʻahaʻa o ka omo ʻana o ka aila. I ka wā o ke kaʻina hana hoʻohana, hiki ke hoʻemi nui ʻia ka nui o ka resin, a ʻaʻole e hoʻonui nui ʻia ka viscosity ʻoiai ma lalo o ke kumu o ka nui o ka hoʻohui, kahi e hoʻomaikaʻi nui ai i nā kūlana hana a me ka hana. Hoʻonui i ka pono hana ma 10% a 20%.
8- Haʻahaʻa dielectric mau
ʻO ka waiwai Dk o nā microspheres aniani hakahaka he 1.2 ~ 2.2 (100MHz), hiki ke hoʻomaikaʻi maikaʻi i nā waiwai dielectric o ka mea.
Nā palakiko no nā momi aniani hakahaka
(1) No ka hoʻololi ʻana i nā plastics ʻenekinia e like me ka nylon, PP, PBT, PC, POM, a me nā mea ʻē aʻe, hiki iā ia ke hoʻomaikaʻi i ke kahe ʻana, hoʻopau i ka hōʻike ʻana i nā fiber aniani, lanakila i ka warpage, hoʻomaikaʻi i ka hana flame retardant, hoʻemi i ka hoʻohana ʻana i nā fiber aniani, a hoʻemi i nā kumukūʻai hana.
(2) ʻO ka hoʻopiha ʻana me ka PVC paʻa, PP, PE, a me ka hana ʻana i nā mea i hoʻopili ʻia, nā paipu a me nā papa e hiki ai i nā huahana ke loaʻa ka paʻa maikaʻi o ka dimensional, hoʻomaikaʻi i ka paʻakikī a me ka mahana kūpaʻa wela, hoʻomaikaʻi i ka hana kumukūʻai o nā huahana, hoʻomaikaʻi i ka pono hana a hoʻemi i nā kumukūʻai.
(3) ʻO ka hoʻopiha ʻana i nā kaula PVC, PE a me nā kaula ʻē aʻe a me nā mea uhi insulating hiki ke hoʻomaikaʻi i ke kūpaʻa wela kiʻekiʻe o ka huahana, ka insulation, ke kūpaʻa waikawa a me ka alkali a me nā waiwai ʻē aʻe a me ka hana hana huahana, hoʻonui i ka hana a hoʻemi i nā kumukūʻai.
(4) ʻO ka hoʻopiha ʻana i ka papa keleawe epoxy resin hiki ke hōʻemi i ka viscosity o ka resin, hoʻonui i ka ikaika kūlou, hoʻomaikaʻi i kona mau waiwai kino a me ka mechanical, hoʻonui i ka mahana hoʻololi aniani, hoʻemi i ka dielectric constant, hoʻemi i ka omo wai, a hoʻemi i ke kumukūʻai.
(5) ʻO ka hoʻopiha ʻana me ka polyester unsaturated hiki ke hōʻemi i ka wikiwiki o ka emi ʻana a me ka wikiwiki o ka wai holoi o ka huahana, hoʻomaikaʻi i ke kūpaʻa ʻana i ka ʻaʻahu a me ka paʻakikī, a emi iho nā lua i ka wā o ka lamination a me ka uhi ʻana. Hoʻohana ʻia ia no nā huahana FRP, nā huila polishing, nā mea hana, a pēlā aku.
(6) ʻO ka hoʻopiha ʻana me ka resin silicone hiki ke hoʻomaikaʻi i nā waiwai kino a me nā mechanical, a ʻo ka nui o ka hoʻopiha ʻana hiki ke hōʻemi nui i ke kumukūʻai, he mea kūpono ia no ka hana ʻana i nā ʻōmole.
