ʻO ka mea BMC (DMC) ka pōkole o nā pūhui hoʻoheheʻe nui, ʻo ia hoʻi, nā pūhui hoʻoheheʻe nui.Ua kapa pinepine ʻia ʻo ia ka unsaturated polyester group molding compound ma Kina.ʻO kāna mau mea maka nui nā prepregs nui i hana ʻia me GF (ʻoki ʻia ke aniani fiber), up (unsaturated resin), MD (filler calcium carbonate) a me nā mea hoʻohui like ʻole.Ua hoʻohana mua ʻia nā mea BMC ma West Germany a me Beretania i ka makahiki 1960, a laila hoʻomohala nui ʻia ma United States a me Iapana i nā 1970s a me 1980s.No ka meaʻO nā mea hoʻoheheʻe nui BMCloaʻa nā waiwai uila maikaʻi loa, nā waiwai mechanical, ka wela wela, ka pale ʻana i ka corrosion kemika, a hoʻololi i nā kaʻina hana hoʻoheheʻe like ʻole, hiki iā lākou ke hoʻokō i nā koi hana o nā huahana like ʻole, no laila ua ʻoi aku ka kaulana i nā mea hoʻohana.
(1) Nā hiʻohiʻona a me ka hoʻohana ʻana o BMC
Loaʻa i ka BMC nā waiwai kino, uila a me nā mīkini, no laila ua hoʻohana nui ʻia, e like me ka hana ʻana i nā ʻāpana mechanical e like me nā ʻāpana pahu pahu, nā paipu intake, nā uhi valve, nā bumper a pēlā aku;Hoʻohana nui ʻia ia i ka mokulele, ka hale hana, nā lako,nā huahana maʻemaʻea me nā mea ʻē aʻe e pono ai ke kūʻē ʻana i ke olai, ka hoʻopaʻa ahi, ka nani a me ka lōʻihi;Ma kāna kahua uila maʻamau, ʻoi aku ka nui o kāna hoʻohana ʻana.
(2) Nā huahana maʻamau
Nā ʻāpana uila (insulator, hoʻololi 29, pahu mika,pūpū hoʻoheheʻe kaapuni, pahu pahu, nā pūpū huahana electromechanical hale a pāʻoihana paha), nā ʻāpana kaʻa (ke kukui kukui, ka puka hope, ka pūpū leo, a me nā mea ʻē aʻe), ka pūpū mika, ka pūpū leo.
(3) BMC hana ʻana
ʻO ka mīkini hoʻoheheʻe BMC he mea nui ia no ka BMC bulk material, i koi ʻia i loko o ka pahu BMC ma o ka BMC feeder, a laila hoʻouna ʻia i mua o ka barela ma o ka wili, a laila hoʻokomo ʻia i loko o ka lua mold no ka mālama ʻana a me ka hoʻoheheʻe ʻana.
ʻO ka BMC kahi mea thermosetting.ʻAʻole pono ke kiʻekiʻe loa ka mahana o ka pahu o ka mīkini hoʻoheheʻe injection.Hoʻonohonoho maʻamau ia ma 60 degere e hoʻomaʻamaʻa i ke kahe o nā mea.
ʻO ka mīkini hoʻoheheʻe ʻo BMC he mea hana ʻoihana no ka hana ʻana i nā mea lumpy thermosetting.Aia kahi hoʻonohonoho o ka ʻōnaehana hydraulic i ka ʻāpana hānai, e hoʻoikaika i nā mea puʻupuʻu i loko o ka pahu i ka wā e manaʻo ʻia ai ka wili.He kūpono ka mīkini hoʻoheheʻe BMC no nā mold me ka paʻakikī paʻakikī, i hana ʻia e ka hoʻoheheʻe ʻana, me ka maikaʻi o ka huahana kiʻekiʻe a me ka ikaika haʻahaʻa haʻahaʻa.
ʻO nā ʻano hana hoʻoheheʻe BMC e pili ana i ka hoʻoheheʻe ʻana, ka hoʻololi ʻana a me ka hoʻoheheʻe ʻana.I kēia mau lā, ʻo ka hoʻoheheʻe ʻana i ka injection ke ʻano nui.
① ʻO ke ʻano hoʻoheheʻe ʻana, e ʻike i ke ʻano hana hoʻoheheʻe SMC.
② Hoʻololi i ke ʻano hoʻololi.Loaʻa i nā mea hana ke ʻano ipu a me ke ʻano piston kōkua, ʻo ka nui o ke ʻano piston auxiliary.
