Ua hoʻomohala maikaʻi ʻia ka Fluoroelastomer a hoʻokomo ʻia i loko o ka hana ʻenehana e DuPont i ka waena o 1950s no nā makahiki he 60. He maikaʻi ka aila kū'ē, kiʻekiʻe wela kū'ē, concentrated kaʻakika kū'ē, alkali kū'ē, radiation kū'ē, corrosion kū'ē, ikaika oxidant kū'ē, ikaika kemika kū'ē, maikaʻi kinoea tightness, maikaʻi kino a me ka mechanical waiwai, a me ka uila insulation, haʻahaʻa compression a mau deformation. Ma ke ʻano he lāʻau synthetic kūikawā, hoʻohana nui ʻia ia i ka ʻoihana kemika, aerospace, kaʻa, ʻoihana ʻaila, mīkini, uila a me nā māla ʻē aʻe. Loaʻa i ka Fluorine rubber ka hana maikaʻi loa a me nā hiʻohiʻona noi ākea. Hoʻokumu kūʻokoʻa ʻia e ka ʻōpala fluoroether haʻahaʻa haʻahaʻa o Kina ua hoʻohana maikaʻi ʻia i ka hana ʻana o Long March moʻo o ka hoʻokuʻu ʻana i nā kaʻa servo mechanical seal, a hui pū ʻia i loko o nā mokulele hakakā, nā pahu hou ma ka paipu aila, ka uila kaapuni sheathing a me nā mea pono ʻē aʻe. I ka hoʻohana kīwila no nā ʻāpana kaʻa, e hoʻonui ana i kēlā me kēia lā, i ka ʻoihana ʻoihana e hoʻoikaika mālie i ka hoʻohana ʻana i ka fluorine rubber.

ʻOiai he kūpaʻa maikaʻi ka fluorine rubber i ka media a me ka wela kiʻekiʻe e like me ka mea i ʻōlelo ʻia ma luna, aia kekahi mau mea ʻino a me nā paʻakikī i ke kaʻina hana a me ka hana ʻana i nā huahana fluorine rubber, ma waena o nā mea maʻamau e hoʻopau ʻia i nā mea make i ka wā e hui ai, wehe ʻia ka hoʻomaʻemaʻe ʻana i nā wili paʻa, i kekahi manawa ʻike ʻia nā kiko keʻokeʻo liʻiliʻi i ka wā e ʻoki ai a nānā ʻia ma hope o ka hoʻokuʻu ʻia ʻana o ke kiʻiʻoniʻoni, maʻalahi nā huahana i ka uhae ʻana, ka ʻili a me nā ʻōpala. ka lāʻau, ka deformation o ka huahana, ka hoʻoheheʻe ʻana i ka mold koʻikoʻi a me nā mea ʻē aʻe e pili ana i ka maikaʻi o ka huahana. Hoʻopilikia ʻia ka maikaʻi o nā huahana.

I ka pane ʻana i nā mea ʻino ma luna o ke kaʻina hana, ua hana ʻia nā hopena i lalo.

Lae 1. He mea make i hui 'ia e ka huila fluorine

ʻO ke kumu o ka hui pū ʻana me ka sulfur melemele a i ʻole nā ​​​​huahana melemele sulfur, ʻaʻohe nui o nā ʻoihana i kahi mīkini hoʻomaʻemaʻe fluorine rubber, e hoʻomaʻemaʻe pinepine i nā mea sulfur melemele ʻē aʻe, ʻaʻole i hoʻomaʻemaʻe ʻia, a i ʻole nā ​​​​mea i hoʻopaʻa ʻia me ka sulfur melemele a i ʻole ka wai. ʻO ka hopena, ʻo ka mīkini kūikawā maikaʻi loa, inā ʻaʻole, pono nō i ka hoʻololi ʻana o ka pulupulu fluorine ma mua o ka hoʻomaʻemaʻe ʻana, pono e hoʻomaʻemaʻe loa i ka pā baffle a me ka pā mea, e pale loa i ka hoʻopili ʻana me ka wai a me ka sulfur melemele, nā mea hoʻohana i nā mea hana kūikawā, kahi mea a spoon, e pale i ka hoʻohaumia ʻana. E mālama i ka calcium hydroxide a me ka magnesium oxide i sila a mākaukau e hoʻohana.

Lae 2. ʻO ke ʻano o ka ʻōwili paʻa

ʻO ka mea nui ma ke kaʻina hui ʻana ma ka mīkini wehe, ʻo ka mea hao i hoʻopaʻa ʻia i loko o ka wili hope, a i ʻole i ka manawa like i ʻōwili ʻia ma mua a ma hope o nā wili ʻelua, ka hopena i ka mea mua ʻaʻole hiki ke hoʻohuli i ka hoʻomaʻemaʻe ʻana, a ʻo ka mea hope me ka mea hoʻohui i hoʻopili maʻalahi ʻia i loko o nā flakes a hāʻule, e hopena i ka dispersion uneven. ʻO ke kumu nui o ka mea pipili fluorine e pili ana i nā wili, ʻo ia ka Menny haʻahaʻa a i ʻole ka haʻahaʻa haʻahaʻa molekala o ka fluorine rubber. ʻO ka hoʻonā ʻana i kēia pilikia, ʻo ia ke koho ʻana i ka ʻōpala maka me kahi viscosity ma kahi o 70, a me ka hoʻohana ʻana i ka ʻōpala maka me ka hāʻawi ʻana i ke kaumaha molecular haiki, a laila hoʻohui i kahi liʻiliʻi o ka wax Brazilian a i ʻole fluorine wax a i ʻole polyethylene kaumaha haʻahaʻa haʻahaʻa i loko o ke ʻano, hiki iā ia ke hoʻoponopono i ke ʻano o ka wili.

Lae 3. E pili ana i nā kiko keʻokeʻo liʻiliʻi i loko o ka ʻōpala hui

ʻO ia ma muli o kekahi pauka dispersion o ka fluorine rubber compounding agent ʻaʻole like, a i ʻole ma muli o ka pauka moisture caking, e like me ka waikawa absorbers calcium hydroxide, magnesium oxide a me ka honua diatomaceous, barium sulfate, a me nā mea ʻē aʻe, ka hopena, e pale ai i ka hoʻohuihui ʻana i ka wai a hoʻoikaika i ke kaʻina hana.

Lae 4. He maʻalahi ka haʻalulu o ka huahana

ʻO ke kumu, ʻoi aku ka mānoanoa burr, ʻokiʻoki i ka wā e haehae ai, a i ʻole ka ʻōpala me ka paʻa loa, mai loko mai o ka ʻāpana burr i hoʻopaʻa ʻia i loko o ka mold, maʻalahi mai ka huahana a burr ma mua o ka haehae ʻana, ka ikaika ʻole i ka wā e hoʻomaka ai i ka mold, maʻalahi e haehae i ka huahana. I kekahi manawa, ʻoʻoleʻa ka hana ʻana o ka lua, a pili paha ka mea hoʻopili i ka mold, a i ka pau ʻana o ka vulcanization, pilikia ia i ka wehe ʻana i ka ʻōpala a haehae i ka huahana. Eia kekahi, ʻoi aku ka kiʻekiʻe o ka wela vulcanization, e lilo ai nā huahana i mea palupalu a maʻalahi hoʻi e haehae. No ka mea maʻamau i luna, hiki ke hoʻoholo ʻia mai nā ʻano aʻe: pono ka hoʻoheheʻe ʻana o ka mold i ka ʻawaʻawa maikaʻi o ka lua Ra emi ma mua o 0.8, ʻaʻole nui ke ākea kūpono, ʻoi aku ka maikaʻi o ka mana o ka vulcanization i waiho ʻia ma waena o 170 degere, a pololei ke kaupaona ʻana.

Lae 5. ka pohā pilikia ka emi ʻana a me

Ma muli o ke kaomi ʻana i ka wā i wehe ʻia ai ka ʻōpala, ka hoʻohaʻahaʻa ʻana o ka fluorine rubber, a paʻa ka ʻāpana burr i ka ʻōpala me ka ʻili ma waena, no laila ma waena o ka ʻāpana huahana a me ka burr e hoʻoulu ai i ka ikaika tensile, i mea e hoʻokaʻawale ai ka huahana a me ka burr, ke hoʻonui ʻia ka pā i ka ʻāpana o ka huahana, e hoʻohaʻahaʻa a me ka haki ʻana. ʻO ka hoʻonā e hoʻemi pono i ka wela vulcanization, e koho i ka Menny viscosity ma kahi o 70 [ML1 + 4] 121 degere, ʻoiai ʻo ke degere kūpono kūpono e kūpono, ʻaʻole i wehe a paʻa loa.

Lae 6. Ua like ka lihi me ke ahi

He kiʻekiʻe loa ka mahana vulcanization, ʻoi aku ka mānoanoa o nā huahana, kūpono e hoʻemi i ka mahana vulcanization hiki ke lanakila.

Lae 7. Aia nā meheu ma ka hui

I t ma muli o ka ʻāpana ʻūhā o ka mea adhesive ʻaʻole i hui pū ʻia, a i ʻole ma muli o ka ʻōpala adhesive he haumia a i ʻole ka aila fouling, ʻo ka hopena ka mālama ʻana i ka mea i hoʻopaʻa ʻia i loko o ka mālama ʻana, ka lawe ʻana, ka hoʻouka ʻana i ke kāpili maʻemaʻe, e pale i ka pollution.

Lae 8. Ka nele o ke kāpili

E pili ana i ke ʻano o ka mold a me ka wai o ke kāpili. ʻOi aku ka maikaʻi o ka hoʻopaʻa ʻia ʻana i ka nele o ke kāpili ma mua o ka poʻo hāmama. ʻO ka hoʻonā ka hoʻoponopono ʻana i ka wai o ka ʻōpala a wehe i ka lua ea i loko o ka lua mold.

Lae 9. Hoʻololi ʻano huahana

Ma muli o ka nui o ka fluorine rubber shrinkage rate, ma hope o ka hoʻoheheʻe ʻana i ka anisotropy shrinkage huahana, ʻokoʻa ka coefficient o ka hoʻonui ʻana o ka wela o ka lāʻau i nā ʻaoʻao like ʻole, ʻelua kaʻina hana vulcanization e hana hou i ka cross-linking. o ka deformation huahana.

Lae 10. Mold stain koʻikoʻi hanana

Hoʻohana maʻamau mākou i ka 26 type fluorine rubber, phenol vulcanization system, i ke kaʻina hana vulcanization e hana ʻia ʻo HF, he waika ikaika loa ia, he hopena corrosive nui i ka mold, ʻo ke kumu e hoʻohui ai i ka waikawa absorbent ʻo ia ke komo i ka HF i hana ʻia, e pale i ka pollution o ka mold. ʻO ka hopena, ʻo ia ka hoʻohana ʻana i ka calcium hydroxide a me ka magnesium oxide e like me ke ʻano, ʻo ke ʻano maʻamau he 6 mau ʻāpana a me 3 ʻāpana, a hiki ke hoʻohui ʻia ka wax Brazilian i ke ʻano, hiki ke neʻe i ka ʻili i ka wā o ka vulcanization e hana i kahi kiʻiʻoniʻoni e pale ai i ka pala mai ka haumia.

Hiki ke hoʻonā ʻia nā mea maʻamau he ʻumi ma luna o ka hana ʻana a me ka hoʻoili ʻana o ka lāʻau fluorine e nā ʻano hana like ʻole.
