Hoʻohālikelike ʻia nā pono a me nā pōʻino o nā mea ʻelua.

ʻO ka waiho ʻana o ka lima he kaʻina hana open-mold i kēia manawa no 65% okīʻaha anianinā mea hoʻohui polyester i hoʻoikaika ʻia. ʻO kāna mau mea maikaʻi ʻo ia ka loaʻa ʻana o ke kūʻokoʻa nui i ka hoʻololi ʻana i ke ʻano o ka mold, haʻahaʻa ke kumukūʻai mold, ikaika ka adaptability, ʻike ʻia ka hana huahana e ka mākeke, a haʻahaʻa ke kālā. No laila, kūpono loa ia no nā ʻoihana liʻiliʻi, akā no nā ʻoihana moana a me nā ʻoihana aerospace, kahi maʻamau kahi hapa nui. Eia nō naʻe, aia kekahi mau pilikia ma kēia kaʻina hana. Ināʻoi aku ka nui o ka hoʻokuʻuʻana o ka huila organik (VOC) i ka maʻamau, he hopena nui ia i ke olakino o nā mea hana, ua maʻalahi ka naloʻana o nā limahana, he nui nā kapu i nā mea iʻaeʻia, ua haʻahaʻa ka hana huahana, a ua pau ka resin. a hoʻohana nui ʻia, ʻoi aku ka nui o ka huahana. ʻAʻole paʻa ka maikaʻi. ʻO ka hapa okīʻaha aniani a me ka resin, ka mānoanoa o nā ʻāpana, ka nui o ka hana ʻana o ka papa, a me ke ʻano like ʻole o ka papa e hoʻopili ʻia e ka mea hoʻohana, a pono ka mea hoʻohana e loaʻa i ka ʻenehana ʻoi aku ka maikaʻi, ka ʻike a me ka maikaʻi.ʻO ka resinʻO ka maʻiʻo o nā huahana kau lima ma kahi o 50%-70%. ʻO ka hoʻokuʻu ʻana o ka VOC o ke kaʻina wehe ʻana ma mua o 500PPm, a ʻo ka volatilization o styrene he kiʻekiʻe e like me 35% -45% o ka nui i hoʻohana ʻia. ʻO nā hoʻoponopono o nā ʻāina like ʻole he 50-100PPm. I kēia manawa, hoʻohana ka hapa nui o nā ʻāina ʻē i ka cyclopentadiene (DCPD) a i ʻole nā ​​resins hoʻokuʻu haʻahaʻa haʻahaʻa, akā ʻaʻohe mea kūpono no ka styrene ma ke ʻano he monomer.

ʻO ka resin vacuumʻO ke kaʻina hana hoʻolauna he kaʻina hana haʻahaʻa haʻahaʻa i hoʻomohala ʻia i nā makahiki 20 i hala iho nei, kūpono loa no ka hana ʻana i nā huahana nui. ʻO kāna mau pōmaikaʻi penei:

(1) He hana maikaʻi loa ka huahana a me ka hua kiʻekiʻe.Ma ka hihia o ka mea likeaniani uilaHiki ke hoʻomaikaʻi ʻia nā mea maka, ka ikaika, ʻoʻoleʻa a me nā mea kino ʻē aʻe o nā mea i hoʻokomo ʻia i ka resin vacuum e ʻoi aku ma mua o 30% -50% i hoʻohālikelike ʻia me nā ʻāpana waiho lima (Papa 1). Ma hope o ka hoʻopaʻa ʻana o ke kaʻina hana, hiki ke kokoke i ka 100%.

Papa 1Hoʻohālikelike hana o ka polyester maʻamauaniani uila

(2) Paʻa ka maikaʻi o ka huahana a maikaʻi ka hana hou.ʻAʻole liʻiliʻi ka maikaʻi o ka huahana e nā mea hoʻohana, a aia kahi kiʻekiʻe o ke kūlike inā ʻo ia ka mea like a i ʻole ma waena o nā ʻāpana. Hoʻokomo ʻia ka ʻike fiber o ka huahana i loko o ka mold e like me ka nui i ʻōlelo ʻia ma mua o ka hoʻopiʻi ʻia ʻana o ka resin, a ʻo nā mea i loaʻa i ka lākiō resin mau, maʻamau 30% -45%, no laila ke kūlike a me ka hana hou ʻana o ka huahana. ʻoi aku ka maikaʻi ma mua o nā huahana hana lima. nui aku, a emi mai na hemahema.

(3) Hoʻomaikaʻi ʻia ka hana anti-fatigue, hiki ke hoʻemi i ke kaumaha o ka hale.Ma muli o ke kiʻekiʻe o ka fiber content, ka porosity haʻahaʻa a me ka hana kiʻekiʻe o ka huahana, ʻoi aku ka maikaʻi o ka ikaika interlaminar, ʻoi aku ka maikaʻi o ke kūpaʻa luhi o ka huahana. Ma keʻano o ka ikaika likeʻole a iʻole nā ​​koi koʻikoʻi, hiki i nā huahana i hanaʻia e ke kaʻina hana induction vacuum ke hoʻemi i ke kaumaha o ka hale.

(4) Pili kaiapuni.ʻO ke kaʻina hana infusion resin vacuum he kaʻina hana hoʻoheheʻe ʻia kahi e hoʻopaʻa ʻia ai nā mea hoʻoheheʻe a me nā mea haumia ea ʻona i loko o ka ʻeke pahu. Loaʻa nā ʻāpana liʻiliʻi wale nō i ka wā e hoʻoheheʻe ʻia ai ka ʻumehana (hiki ke kānana) a wehe ʻia ka pahu resin. ʻAʻole ʻoi aku ka nui o nā hoʻokuʻu VOC i ka maʻamau o 5PPm. Hoʻomaikaʻi nui kēia i ke kaiapuni hana no nā mea hana, hoʻopaʻa i ka limahana hana, a hoʻonui i ka nui o nā mea i loaʻa.

(5) Maikaʻi ka pono o ka huahana.Hiki i ke kaʻina hana hoʻokomo i ka resin vacuum ke hoʻoikaika i nā iwi ʻaoʻao, nā hale sandwich a me nā mea hoʻokomo ʻē aʻe i ka manawa like, e hoʻomaikaʻi ai i ka pono o ka huahana, no laila hiki ke hana ʻia nā huahana nui e like me nā puʻupuʻu, nā moku moku a me nā superstructures.

(6) E ho'ēmi i ka hoʻohanaʻana i nā mea waiwai a me ka hana.Ma ka hoʻonohonoho like, hoʻemi ʻia ka nui o ka resin e 30%. ʻO ka liʻiliʻi o ka ʻōpala, ʻoi aku ka nui o ka make resin ma mua o 5%. ʻOi aku ka nui o ka hana hana, ʻoi aku ma mua o 50% ka mālama ʻana i ka hana ma mua o ke kaʻina hana lima. ʻOi loa i ka hana ʻana i nā geometries nui a paʻakikī o ka sandwich a me nā ʻāpana i hoʻoikaika ʻia, ʻoi aku ka nui o ka waiwai a me ka mālama ʻana i ka hana. No ka laʻana, i ka hana ʻana i nā rudder vertical i ka ʻoihana mokulele, ua hoʻemi ʻia ke kumukūʻai o ka hoʻemi ʻana i nā mea hoʻopaʻa e 365 e 75% i hoʻohālikelike ʻia me ke ʻano kuʻuna, ʻaʻole i loli ke kaumaha o ka huahana, a ʻoi aku ka maikaʻi o ka hana.

(7) Maikaʻi ka pololei o ka huahana.ʻOi aku ka ʻoi aku o ka pololei o ka dimensional (ka mānoanoa) o nā huahana kaʻina hana hoʻokomo resin ma mua o nā huahana waiho lima. Ma lalo o ka hoʻonohonoho like, ʻo ka mānoanoa o nā huahana ʻenehana diffusion resin vacuum maʻamau he 2/3 o nā huahana waiho lima. ʻO ka mānoanoa o ka huahana ma kahi o ± 10%, ʻoiai ke kaʻina hana kau lima ma ke ʻano he ± 20%. ʻOi aku ka maikaʻi o ka ʻili o ka huahana ma mua o nā huahana kau lima. ʻO ka paia o loko o ka huahana hood o ke kaʻina hoʻokomo resin vacuum he maʻemaʻe, a ʻo ka ʻili ke hana maoli i kahi ʻāpana resin-waiwai, ʻaʻole ia e koi i ke kapa hou. Hoʻemi i ka hana a me nā mea hana no ka hana ʻana a me ka pena pena.

ʻO kaʻoiaʻiʻo, ʻo ke kaʻina hana hoʻolauna resin vacuum i kēia manawa he mau hemahema kekahi:

(1) He manawa lōʻihi ka hana hoʻomākaukau a ʻoi aku ka paʻakikī.Pono ka hoʻonohonoho pono ʻana, ka hoʻokomo ʻana i ka media diversion, nā paipu hoʻoheheʻe, ka hoʻopaʻa ʻana i ka vacuum maikaʻi, a me nā mea ʻē aʻe. No laila, no nā huahana liʻiliʻi liʻiliʻi, ʻoi aku ka lōʻihi o ke kaʻina hana ma mua o ke kaʻina hana lima.

(2) ʻOi aku ka nui o ke kumukūʻai hana a ʻoi aku ka nui o nā ʻōpala.ʻO nā mea kōkua e like me ka pahu pahu kiʻiʻoniʻoni, ke ʻano diversion medium, ka lole hoʻokuʻu a me ka paipu hoʻoheheʻe ʻia nā mea āpau, a he nui nā mea i lawe ʻia i kēia manawa, no laila ʻoi aku ka kiʻekiʻe o ke kumukūʻai hana ma mua o ke kaʻina hana lima. Akā ʻoi aku ka nui o ka huahana, ʻoi aku ka liʻiliʻi o ka ʻokoʻa. Me ka loaʻa ʻana o nā mea kōkua, e liʻiliʻi a liʻiliʻi kēia kumukūʻai. ʻO ka noiʻi o kēia manawa e pili ana i nā mea kōkua i hiki ke hoʻohana pinepine ʻia he kuhikuhi hoʻomohala o kēia kaʻina hana.

(3) Loaʻa i ka hana kaʻina hana kekahi mau pilikia.Maikaʻi no nā huahana hoʻolālā nui a paʻakikī, i ka wā e pau ai ka infusion resin, maʻalahi ke ʻoki ʻia ka huahana.

No laila, ʻoi aku ka maikaʻi o ka noiʻi mua, ka mālama ʻana i ke kaʻina hana a me nā hana hoʻoponopono kūpono e pono ai e hōʻoia i ka holomua o ke kaʻina hana.
