I ka wā e koho ai i ka mea kūpono no kāu papahana, he mea nui e noʻonoʻo i nā pono a me nā pōʻino o kēlā me kēia koho. Ma kēia pou blog, e hoʻohālikelike mākou i ʻelua mau mea maʻamau i hoʻohana ʻia i ka hana ʻana a me ka ʻenekinia: silicone rubber a me viton.
He aha ka silicone rubber a me ka viton?
ʻO ka silicone rubber a me ka viton ʻelua mau mea i hoʻohana pinepine ʻia i ka hana ʻana a me ka ʻenekinia. Loaʻa iā lākou nā pōmaikaʻi a me nā hemahema, pono e noʻonoʻo ʻia i ka wā e hoʻoholo ai i kahi e hoʻohana ai no kahi kumu kikoʻī.
ʻO ka lāʻau silikoni a me ka viton ʻelua ʻano like ʻole o ka elastomer, a i ʻole ka lāʻau synthetic. Hoʻohana maʻamau ʻia nā mea ʻelua i nā noi kahi e koi ʻia ai ka maʻalahi, ka lōʻihi, a me ke kūʻē ʻana i ka wela a me nā kemika. Eia nō naʻe, aia kekahi mau ʻokoʻa koʻikoʻi ma waena o nā mea ʻelua e noʻonoʻo ʻia ke koho ʻana i kahi mea no kahi noi.
ʻO ka pahu silikoni kahi polymer synthetic i hana ʻia me nā ʻātoma silika a me ka oxygen. Loaʻa i ka silicone rubber ka nui o nā noi ma muli o kāna hui kūʻokoʻa o nā waiwai. He kūpaʻa ia i nā wela wela, wela a me ke anuanu, e lilo ia i mea kūpono no ka hoʻohana ʻana i nā noi kahi mea nui ka wela wela. Loaʻa iā Silicone rubber nā waiwai insulation uila maikaʻi loa a kū i ke kukui UV a me ka ozone, kūpono ia no ka hoʻohana ʻana i nā noi waho. Eia naʻe, ʻaʻole i like ka pae o ke kūʻē ʻana i ka wai i hoʻokumu ʻia i ka aila e like me ka viton.
ʻO ka Viton kahi lāʻau synthetic i hana ʻia mai ka fluoroelastomer, he copolymer o ka vinylidene fluoride a me ka hexafluoropropylene. ʻO ka Vinylidene fluoride kahi mea hoʻoheheʻe fluorinating ikaika, e hāʻawi ana i ka viton i kona kūpaʻa maikaʻi loa i ka aila, nā wahie, a me nā wai e pili ana i ka petroleum. ʻAʻole kūʻē ʻo Viton i nā wela kiʻekiʻe, e lilo ia i mea kūpono no ka hoʻohana ʻana i nā gaskets a me nā sila i nā ʻenekini a me nā wahi wela kiʻekiʻe. ʻAʻole hiki ke wāwahi ʻia ʻo Viton e like me ka silicone rubber ke ʻike ʻia i nā wela kiʻekiʻe. Eia nō naʻe, ʻaʻole like ka viton i ke ʻano o ka pale ʻana i ke kukui UV a me ka ozone e like me ka silicone rubber.
He aha nā ʻokoʻa ma waena o ka silicone rubber a me ka viton?
He mau ʻokoʻa koʻikoʻi ka Silicone rubber a me Viton e hoʻokaʻawale iā lākou. No ka mea, he haʻahaʻa haʻahaʻa haʻahaʻa ka pale ʻana o ka wela silicone ma mua o Viton, no laila kūpono ia no nā noi ʻaʻole koi i ka nui o ka pale wela. Hoʻohui ʻia, ʻoi aku ka maʻalahi o ka silicone rubber ma mua o Viton, e ʻoi aku ka maikaʻi o ia no nā noi i mea nui ka loli. ʻO ka mea hope loa, ʻoi aku ka liʻiliʻi o ke kumulāʻau silicone ma mua o Viton, e lilo ia i koho ʻoi aku ka waiwai no nā noi he nui.
ʻO Viton® kahi mea hana kiʻekiʻe synthetic rubber i hoʻohana nui ʻia i nā O-rings, ʻōnaehana wahie a me nā noi hoʻokele emission. Ua kūpono hoʻi ʻo Viton® no nā ʻoihana a me nā mea he nui nā hoses uwea kaʻa kahi e pono ai ke kū'ē i nā wahie, nā aila, nā lubricants a me nā kemika koʻikoʻi.
He elastomer ka silikoni i haku ʻia me ke silikoni—he polymer iho—i loko o ke silika me ka oxygen, carbon, hydrogen, a i kekahi manawa nā mea kemika ʻē aʻe. Hoʻohana nui ʻia ʻo Silicone rubbers i ka ʻoihana, a he nui nā ʻano hana. Hoʻokahi a i ʻole ʻelua ʻāpana o nā polymers ka silikoni, a loaʻa paha nā mea hoʻopihapiha e hoʻomaikaʻi ai i nā waiwai kikoʻī.
He aha nā pōmaikaʻi o ka silicone rubber?
He nui nā mea maikaʻi o ka rubber silicone ma mua o nā ʻano lāʻau ʻē aʻe. He kūpaʻa ʻo ia i nā wela wela, wela a me ke anu, a hiki ke maʻalahi i nā ʻano wela. He kūpaʻa nō hoʻi ia i ka ʻelemakule, ke kukui UV, ka ozone, a me ka oxygen. ʻAʻole hiki ke wāwahi maʻalahi ka silikoni, no laila he lōʻihi kona ola.
He aha nā pōmaikaʻi o ka viton?
ʻO Viton kahi lāʻau synthetic i hoʻohana ʻia i nā noi like ʻole e koi ana i ke kūʻē ʻana i nā wela kiʻekiʻe, nā kemika, a me nā aila. He kūpaʻa maikaʻi loa ia i ka wela, nā kemika, a me nā aila, kūpono ia no ka hoʻopaʻa ʻana i nā noi. ʻOi aku ka pale ʻana o Viton i nā mahana anuanu ma mua o nā ʻōpala ʻē aʻe, no laila kūpono ia no nā noi i nā kaiapuni koʻikoʻi.
Pehea ka hoʻohālikelike ʻana o ka silicone rubber a me ka viton ma ke ʻano o ke kumukūʻai?
Aia kahi ʻokoʻa nui i ke kumukūʻai o ka silicone rubber a me ka viton. ʻOi aku ka liʻiliʻi o ka silikoni ma mua o ka viton. ʻO ka ʻokoʻa o ke kumukūʻai ma muli o ka ʻokoʻa o nā kumukūʻai hana. Hana ʻia ʻo Viton mai nā mea synthetic, aʻo ka silicone rubber i hana ʻia mai nā mea kūlohelohe.
Pehea ka hoʻohālikelike ʻana o ka silicone rubber a me ka viton i ke ʻano o ka lōʻihi?
ʻO ka silikoni a me ka viton nā mea paʻa loa. Eia naʻe, ʻoi aku ka lōʻihi o ka viton ma mua o ka silicone rubber. Hiki i ka Viton ke pale i nā mahana kiʻekiʻe a ʻoi aku ke kūpaʻa i nā kemika, ʻoiai ʻoi aku ka maʻalahi o ka silicone rubber a me ka haʻahaʻa haʻahaʻa.
Pehea ka hoʻohālikelike ʻana o ka silicone rubber a me ka viton i ke ʻano o ke kūʻē ʻana i nā kemika?
ʻOiai ʻo ka silicone rubber a me ka viton ke kūpaʻa i nā kemika he nui, aia kekahi mau ʻokoʻa nui ma waena o nā mea ʻelua. ʻOi aku ka paʻa o Viton i nā aila a me nā wahie, ʻoiai ʻoi aku ka paʻa o ka silicone rubber i ka wai a me ka wela. Ma ke ʻano o nā kemika kikoʻī, ʻoi aku ka maikaʻi o ka viton e kūʻē i ka acetic acid, acetone, a me ka ʻaila mineral, ʻoiai ʻoi aku ka maikaʻi o ka silicone rubber ke pale aku i ka benzene, Freon, a me ka peroxide.
Pehea ka hoʻohālikelike ʻana o ka silicone rubber a me ka viton i ke ʻano o ka pale ʻana i ka wela?
Hiki ke pale aku i nā wela a hiki i ka 180°C (356°F), ʻoiai hiki i ka viton ke pale i nā mahana a hiki i 200°C (392°F). Ma ke ʻano o ka pale ʻana i ka wela, ʻoi aku ka maikaʻi o ka viton no nā noi e koi ana i ka hoʻonui ʻia ʻana i nā wela kiʻekiʻe.
