Hōʻike Pōkole:
Hoʻohana ākea ka resin PC (polycarbonate) i nā ʻāpana hoʻoheheʻe i nā huahana uila, nā pūpū mea uila a me nā huahana uila.
Hoʻohana ākea nā kēpau kēpau kēpau PC i nā huahana uila, nā pūpū mea uila a me nā huahana uila.
He aha ka kēpau PC?
He aha ka resin PC (polycarbonate) i ʻike pinepine ʻia ma ke ʻano he polycarbonate, ma muli o ka maikaʻi o nā pono mechanical, i ʻike pinepine ʻia ma ke ʻano he pelu. Loaʻa i ka PC nā ʻano o ka ikaika mechanical kiʻekiʻe, ka laulā o ka mahana, ka hana hoʻopī uila uila (akā ʻaʻole hoʻololi ʻia ka pale arc), ke kūpaʻa dimensional maikaʻi a me ka transparency.
ʻO ke kala kumu o PC he kala ʻole a aniani. Hiki ke kiʻi ʻia nā kala like ʻole, translucent a me ka opaque a me nā waiwai diffusion māmā e ka hoʻohui ʻana i ka toner a i ʻole ka pūʻulu haku. He mea maʻalahi kēia e hana i nā aka kukui a me nā ʻāpana ʻē aʻe me nā kala like ʻole. Nui a nui nā huahana i hoʻomaikaʻi ʻia e ka PC, e like me ke aniani aniani, mea hoʻopihapiha mineral, mea pale ahi a me nā mea ʻē aʻe ʻē aʻe.
Loaʻa ka maikaʻi ʻole o ka PC a me ka mahana hana kiʻekiʻe, no laila ʻo ka hana ʻana i nā māka he nui o nā mea i hoʻololi ʻia e koi ai i kahi hanana injection plasticized kūikawā.
Nā kala ʻokoʻa ma hope o ka hoʻohui ʻana i ka toner a i ʻole ka masterbatch
ʻO ke kala kumu o ka kēpau PC
ʻO nā palena kino o ka kēpau PC
Ka nui: 1.18-1.22 g / cm ^ 3 laina hoʻonui hoʻonui: 3.8 * 10 ^ -5 cm / C mahana wela o ka mahana: 135 C haʻahaʻa mahana - 45 CPC (Polycarbonate) ʻaʻohe kala, pale ʻole, pale ʻole i ka wela, pale-hopena, papa BI lapalapa o ka lapalapa ahi, a loaʻa iā ia nā pono mechanical maikaʻi i ka mahana hoʻohana maʻamau. Hoʻohālikelike ʻia me polymethyl methacrylate, polycarbonate he maikaʻi hopena kūʻē ʻana, kiʻekiʻe index refact a me ka maikaʻi aaioee hana. Loaʻa iā UL94 V-2 lapalapa ahi me nā mea hoʻohui ʻole. ʻIlihune ka pale ʻaʻahu o polycarbonate. ʻO kekahi mau mea hana polycarbonate no nā noi komohewa e koi ai i kahi lapaʻau kūikawā kūikawā.
He aha ka kēpau PC i hoʻohana ai?
PC mea i wela wela e kū'ē'ē mai, kiʻekiʻe ikaika, maikaʻi paʻakikī, hopena ia'ku, lapalapa retardant, ākea hoʻohana wela huahelu, ole-koʻohune, transparency o i ka 90%, a me ka maikaʻi me mechanical waiwai i loko o ka maʻamau hoʻohana wela. ʻO ke kūpaʻa dimensional kiʻekiʻe, haʻahaʻa loa ka shrinkage, he 0.1% ~ 0.2% maʻamau. Hoʻohana ākea ʻia i: nā pono uila, nā uila pono, nā pono olakino, nā pākaukau, nā mīkini a me nā huahana a me nā pono hana ʻē aʻe.

He aha ka hana hoʻoheheʻe o ka PC resin material?
1. Ka lapaʻau Plastics
ʻOi aku ka kiʻekiʻe o ka loaʻa ʻana o ka wai i ka PC. Pono e hoʻomehana a hoʻomaloʻo ma mua o ka hana ʻana. Hoʻomaloʻo ʻia ʻo PC Maʻemaʻe ma 120 C. Hoʻomaloʻo pinepine ʻia ʻo PC Hoʻololi ma 110 C no nā hola he 4 a ʻoi. ʻAʻole pono ka manawa hoʻomaloʻo ma mua o 10 mau hola. Ma ka laulā, hiki ke hoʻohana i ke ʻano extrusion air-to-air e hoʻoholo inā lawa paha ka hoʻomaloʻo.
Hiki i ke kaulike o nā mea hana hou ke piʻi i 20%. I kekahi mau hihia, hiki ke hoʻohana ʻia i nā mea hana hou he 100%, a kaukaʻi ʻia ka mea kaupaona maoli i nā koina e pono ai ka huahana. ʻAʻole hiki i nā mea i hana hou ʻia ke huikau i nā masterbatches kala like ʻole i ka manawa like, inā ʻaʻole e hōʻino nui ʻia nā waiwai o nā huahana i hoʻopau ʻia.
2. Ke koho ʻana i ka mīkini hoʻoheheʻe
Ma muli o ke kumu kūʻai a me nā kumu ʻē aʻe, hoʻohana nā huahana PC i kēia manawa i nā mea i hoʻololi hou ʻia, keu hoʻi nā huahana uila, akā pono pū kekahi e hoʻonui i ka pale ahi. I ke kaʻina o ka hoʻokumu ʻana i ka PC ahi-retardant PC a me nā huahana oka a pau ʻē aʻe, pono ke kāwili ʻia ʻana o ka ʻōnaehana plasticizing o ka mīkini hoʻoheheʻe ʻana a me ke kūpaʻa o ka popopo. He paʻakikī ke hoʻokō i ka ʻāpala palu maʻamau. Ke koho a me ke kūʻai ʻana, pono nō. E wehewehe ʻia ma mua.
3. Hoʻolālā o ka punahelu a me ka puka pā
ʻO 80-100 C ka mahana anuanu maʻamau, a ʻo 100-130 C ka puluniu aniani, hiki ke hoʻohana ʻia nā huahana liʻiliʻi i ka puka o ka nila, 70% ka hohonu o ka hapa mānoanoa, loaʻa ke apo a me nā huinahā lōʻihi.
ʻO ka nui o ka puka pā, ʻoi aku ka maikaʻi o ka hōʻemi ʻana i nā kīnā o ka hoʻopaʻa ʻana i nā lula. ʻO ka hohonu o ka lua hoʻopau e pono ma lalo o 0.03-0.06mm, a ʻo ka mea holo e like me ka pōkole a me ka pōʻai e hiki ai. ʻO ka pali o ka demoulding ma kahi o 30'-1 kekelē
4. Ka mahana hoʻoheheʻe
Hiki ke hoʻohana ʻia ke kiʻina hana ea e hoʻoholo ai i ka mahana hana. ʻO ka maʻamau, ʻo ka mahana hana a PC he 270-320 C, a ʻo kekahi me nā PC i hoʻololi ʻia a haʻahaʻa ʻia paha he 230-270 C.
5. ʻO ka wikiwiki hoʻokomo
He mea maʻamau ka hoʻohana ʻana i kahi wikiwiki wikiwiki e hoʻohālikelike, e like me ka hoʻololi ʻana a me nā mīkini uila. Lohi ka maʻamau i prototyping wikiwiki.
6, puʻe hope
Hiki ke hoʻemi kūpono ke kaomi hope o kahi 10 mau pa i ka loaʻa ʻole o nā airmarks a me nā kiʻi ʻoniʻoni.
7. Ka manawa paʻa
Inā noho ka mea i ka mahana kiʻekiʻe no ka lōʻihi loa, e hoʻohaʻahaʻa ia, hoʻokuʻu CO2 a huli melemele. Mai hoʻomaʻemaʻe i ka barela me LDPE, POM, ABS a i ʻole PA. E hoʻohana iā PS e hoʻomaʻemaʻe
ʻO ka resin PC kekahi o nā mea hana ʻehā i hoʻohana pinepine ʻia. Ua hoʻohana lōʻihi ʻo Mestech i nā plastics PC a me kāna mau mea hoʻoheheʻe no ka hoʻoheheʻe ʻana e hana i nā ʻāpana plastic. Kūleʻa mākou i ka lawelawe ʻana aku i nā mea kūʻai aku me ka mōlina a me ka hoʻoheheʻe ʻana o kēia ʻano huahana. Inā pono, e ʻoluʻolu kāhea iā mā ou.
