ʻO ke apo hoʻopaʻa Silicone kahi ʻano o ke apo sealing.Hana ʻia ia me nā silica gel ʻē aʻe a hoʻohana ʻia e hoʻoponopono i ka uhi annular i hiki ke hoʻohālikelike i ka āpau ma waena o ka ferrule a i ʻole gasket ma ka bearing.Heʻokoʻa ia mai ke apo sealing i hanaʻia me nā mea'ē aʻe.ʻOi aku ka maikaʻi o ka hana ʻana o ka wai kūʻē a i ʻole leakage.I kēia manawa, hoʻohana nui ʻia no ka hoʻopaʻa ʻana i ka wai a me ka mālama ʻana i nā mea e pono ai i kēlā me kēia lā e like me crisper, rice cooker, water dispenser, lunch box, magnetized cup, coffee pot, etc. aloha ʻia e nā mea a pau.No laila i kēia lā, e nānā hohonu kākou i ke apo sealing silicone.
ʻO ka ʻokoʻa ma waena o ke apo sealing silicone a me nā apo hoʻopaʻa mea ʻē aʻe:
1. Kūleʻa maikaʻi i ka wā
ʻO ka pale ʻana i ka wā e pili ana i kahi ʻano o ka ʻelemakule e like me ka mae ʻana, ka wehe ʻana, ka ʻāʻī, ka poʻo a me ka nalo ʻana o ka ikaika ma muli o ka mana o nā kūlana o waho e like me ka lā pololei a me nā loli wela.ʻO ka radiation ultraviolet ka mea nui e hāpai i ka ʻelemakule o ka huahana.ʻO ka paʻa ʻo Si-O-Si i loko o ka silicone rubber he paʻa loa ia i ka oxygen, ozone a me nā kukui ultraviolet, a he kūpaʻa maikaʻi loa i ka erosion o ka ozone a me nā oxides.Me ka loaʻa ʻole o nā mea hoʻohui, ʻoi aku ka maikaʻi o ka pale ʻana i ka wā, ʻoiai inā hoʻohana ʻia i waho no ka manawa lōʻihi, ʻaʻole ia e pohā.
2. Ka palekana waiwai a me ka palekana o ka nohona
Loaʻa i ka Silicone rubber kona ʻano physiological inertness, ʻaʻohe mea ʻawaʻawa a ʻono ʻole, ʻaʻohe melemele a ʻaʻohe mae ma hope o ka hoʻohana lōʻihi ʻana, a ʻaʻole i hoʻopilikia ʻia e ke kaiapuni o waho.Kūlike ia i nā kūlana ʻai a me ka maʻemaʻe olakino.Hoʻohana nui ʻia i ka meaʻai, lāʻau lapaʻau, alumini kala kala a me nā aila like ʻole.papa kānana haumia ma.
3. Hana maikaʻi i ka hoʻopili uila
ʻO ka silikoni silikoni he mau waiwai insulation uila maikaʻi loa, a maikaʻi loa hoʻi i ka pale ʻana i ka corona (ka hiki ke pale i ka hoʻohaʻahaʻa ʻana i ka maikaʻi) a me ke kūpaʻa arc (ka hiki ke pale i ka deterioration i hoʻokumu ʻia e ka hana kiʻekiʻe-voltage arc).
4. Kiʻekiʻe ea permeability a me ka selectivity i ke kinoea
Ma muli o ka molecular structure o ka silica gel, ʻo ka silica gel sealing apo he maikaʻi ke kinoea permeability a me ke koho maikaʻi ʻana i nā kinoea.Ma ka lumi wela, ʻo ke kinoea permeability o ka silicone rubber i ka ea, nitrogen, oxygen, carbon dioxide a me nā kinoea ʻē aʻe he 30-50 mau manawa kiʻekiʻe ma mua o ka lāʻau maoli.manawa.
5. Hygroscopicity
He haʻahaʻa ka ikehu o ke apo silicone, nona ka hana o ka hoʻomoʻa ʻana a me ka insulating i ka wai i loko o ke kaiapuni.
6. Ke ākea ākea o ke kiʻekiʻe a me ka haʻahaʻa haʻahaʻa
(1).Kūleʻa wela kiʻekiʻe:Ke hoʻohālikelike ʻia me ka pāpaʻi maʻamau, ʻoi aku ka maikaʻi o ke kūpaʻa wela o ke apo sealing i hana ʻia me ka silica gel, a hiki ke hoʻomehana ʻia i ka wela kiʻekiʻe me ka ʻole o ka deformation a me ka hana ʻole ʻana i nā mea ʻino.Hiki ke hoʻohana kokoke mau loa ma 150 ° C me ka hoʻololi ʻole o ka hana, hiki ke hoʻohana mau ʻia ma 200 ° C no nā hola 10,000, a hiki ke hoʻohana ʻia ma 350 ° C no kahi manawa.Hoʻohana nui ʻia i nā manawa e koi ai i ka pale wela, e like me: thermos bottle sealing ring.
(2).Palena wela haʻahaʻa:E paʻakikī a palupalu ka lāʻau maʻamau ma -20°C a -30°C, ʻoiai ʻo ka silikoni ka elasticity maikaʻi ma -60°C a -70°C.Hiki ke pale aku i nā wela haʻahaʻa loa, e like me: cryogenic sealing apo, hiki i ka haʻahaʻa ke hiki i -100°C.
ʻO nā hemahema o nā sila rubber silicone:
(1).ʻAʻole maikaʻi nā waiwai mechanical o ka ikaika tensile a me ka ikaika o ka waimaka.ʻAʻole ʻōlelo ʻia e hoʻohana i nā apo sealing silicone no ka hoʻolōʻihi ʻana, haehae, a me ka ʻaʻahu ikaika i ka hana hana.ʻO ka maʻamau, hoʻohana wale ʻia no ka hoʻopaʻa paʻa.
(2).ʻOiai ua kūpono ka silicone rubber me ka hapa nui o nā aila, nā mea hoʻohui a me nā mea hoʻoheheʻe, a he maikaʻi ka waikawa a me ke kūpaʻa alkali, ʻaʻohe ona kūʻē i ka alkyl hydrogen a me nā aila ʻala.No laila, ʻaʻole kūpono ia no ka hoʻohana ʻana i nā wahi kahi i ʻoi aku ai ke kaomi hana ma mua o 50 paona.Eia kekahi, ʻaʻole ia e ʻōlelo ʻia e hoʻohana i nā sila silikoni i ka hapa nui o nā solvents concentrated, nā aila, nā waikawa concentrated a me nā hoʻonā caustic soda.
(3).Ma ke ʻano o ke kumukūʻai, hoʻohālikelike ʻia me nā mea ʻē aʻe, ʻoi aku ka kiʻekiʻe o ke kumukūʻai hana o ke apo silicone sealing rubber.
