Na Andy mai ka hale hana Baiyear
Hoʻopuka ʻia ma Nowemapa 2, 2022
Eia ke kikowaena nūhou o ka ʻoihana hoʻoheheʻe injection o Baiyear.Ma hope aʻe, e puʻunaue ʻo Baiyear i ke kaʻina hana hoʻoheheʻe i loko o kekahi mau ʻatikala e hoʻolauna i ka nānā ʻana i nā mea maka o ke kaʻina hana hoʻoheheʻe ʻia, no ka mea he nui loa nā ʻike.ʻO ka ʻatikala mua aʻe.
(1).PS (polystyrene)
1. Hana o PS:
ʻO PS kahi polymer amorphous me ka wai maikaʻi a me ka haʻahaʻa haʻahaʻa o ka wai (emi ma lalo o 00.2%).He ʻilika ʻōlinolino maʻalahi ke hana a hana.Loaʻa kāna mau huahana i ka transmittance māmā o 88-92%, ikaika ikaika tinting a me ka paʻakikī kiʻekiʻe.Eia naʻe, palupalu nā huahana PS, hiki i ka pohā o ke koʻikoʻi o loko, maikaʻi ʻole ke kūpaʻa wela (60-80°C), ʻaʻohe mea ʻawaʻawa, a he 1.04g\cm3 (ʻoi aku ka nui ma mua o ka wai).
ʻO ka hoʻohaʻahaʻa ʻana (ʻo ka waiwai maʻamau 0.004-0.007in/in), transparent PS - hōʻike wale kēia inoa i ka ʻike o ka resin, ʻaʻole ka crystallinity.(Kemika a me ke kino waiwai: 'O ka hapa nui o nā PS pā'oihana he 'ano amorphous. He 'ano maika'i 'o PS i ke kūpa'a geometric, thermal stability, optical transmission properties, uila insulating properties, a me ka li'ili'i li'ili'i e komo i ka wai. , akā hiki ke ʻino ʻia e nā ʻakika oxidizing ikaika e like me ka sulfuric acid concentrated, a hiki ke pehu a deform i kekahi mau mea hoʻoheheʻe organik.)
2. Kaʻina hana o PS:
ʻO ka helu hoʻoheheʻe o PS he 166 °C, ʻo ka mahana hoʻoheheʻe maʻamau he 185-215 °C, a ʻo ka wela hoʻoheheʻe ʻana he 180 ~ 280 °C.No nā mea pale ahi, ʻo ka palena kiʻekiʻe ʻo 250 °C, a ʻo ka mahana decomposition ma kahi o 290 °C, no laila ua ākea kona ʻano wela.
ʻO ka mahana wela he 40 ~ 50 ℃, ke kaomi injection: 200 ~ 600bar, ua ʻōlelo ʻia ka wikiwiki o ka injection e hoʻohana i ka wikiwiki o ka injection, a hiki i nā mea holo a me nā puka ke hoʻohana i nā ʻano maʻamau o nā ʻīpuka.ʻAʻole pono e hoʻomaloʻo ʻia nā mea PS ma mua o ka hana ʻana inā ʻaʻole mālama pono ʻia.Inā makemake ʻia ka hoʻomaloʻo ʻana, ʻo nā kūlana maloʻo i ʻōlelo ʻia he 80C no 2-3 mau hola.
Ma muli o ka wela haʻahaʻa haʻahaʻa o PS, hiki ke hoʻopaʻa ʻia a hoʻopaʻa ʻia kekahi mau mole i ka wā e hoʻopau ʻia ai ka wela.ʻOi aku ka wikiwiki o ka hoʻoluʻu ma mua o nā mea maka maʻamau, a hiki i ka manawa wehe ʻana o ka mold ma mua.He pōkole ka manawa plasticizing a me ka manawa hoʻoluʻu, a e hoʻemi ʻia ka manawa pōʻaiapili;ʻoi aku ka maikaʻi o ka ʻōlinolino o nā huahana PS i ka piʻi ʻana o ka mahana o ka mold.
3.Typical applications: packaging products (containers, caps, bottles), disposable medical supplies, toys, cups, knives, tape reels, storm windows a me ka nui o ka hua pahu - pahu pahu.ʻO nā pā pahu ʻiʻo a me nā moa, nā lepili o ka ʻōmole a me nā mea hoʻoheheʻe PS huʻihuʻi, ka pahu huahana, nā mea hale (nā ʻoki, nā pā, a me nā mea ʻē aʻe), nā uila (nā ipu aniani, nā diffuser māmā, nā kiʻi insulating, etc.).
(2).HIPS (polystyrene i hoʻololi ʻia)
1. Hana o HIPS:
ʻO HIPS kahi mea i hoʻololi ʻia o PS.Loaʻa iā ia he 5-15% o ka mea hao i loko o ka mole.ʻO kona paʻakikī ma kahi o ʻehā mau manawa kiʻekiʻe ma mua o ko PS, a ua hoʻomaikaʻi nui ʻia kona ikaika hopena (high impact polystyrene).Loaʻa iā ia ka papa ahi retardant a me ke koʻikoʻi māwae.nā māka, nā māka ʻōlinolino kiʻekiʻe, nā māka ikaika hopena kiʻekiʻe loa, nā māka i hoʻoikaika ʻia i ka fiber aniani, a me nā māka haʻahaʻa haʻahaʻa.
ʻO nā mea koʻikoʻi ʻē aʻe o ka HIPS maʻamau: ka ikaika kulou 13.8-55.1MPa;ikaika tensile 13.8-41.4MPa;elongation ma ka hoomaha 15-75%;mānoanoa 1.035-1.04 g/ml;ʻO nā pōmaikaʻi.He opaque nā ʻatikala HIPS.He haʻahaʻa ka wai o ka HIPS a hiki ke hana ʻia me ka maloʻo ʻole.
2. Nā hiʻohiʻona hana o HIPS:
No ka mea, loaʻa i ka mole HIPS ka 5-15% rubber, e pili ana i kona wai i kekahi ʻano, ʻoi aku ka kiʻekiʻe o ke kaomi injection a me ka mahana.ʻOi aku ka lohi o kona hoʻomaha ʻana ma mua o ka PS, no laila pono ka paʻa paʻa, ka manawa paʻa a me ka manawa hoʻomaha.ʻOi aku ka lōʻihi o ka pōʻaiapili ʻana ma mua o ka PS, a ʻo ka mahana o ka hana ʻana he 190-240 °C.
Hoʻomoʻa mālie nā resins HIPS i ka makū, no laila ʻaʻole pono e hoʻomaloʻo.I kekahi manawa hiki ke hoʻopili ʻia ka nui o ka wai ma ka ʻili o ka mea, e pili ana i ke ʻano o ka maikaʻi o ka huahana hope.Hiki ke hoʻoneʻe ʻia ka makū nui ma ka hoʻomaloʻo ʻana ma 160 ° F no 2-3 mau hola.Aia kekahi pilikia "keʻokeʻo keʻokeʻo" kūikawā ma nā ʻāpana HIPS, hiki ke hoʻomaikaʻi ʻia ma ka hoʻonui ʻana i ka mahana o ka mold a me ka ikaika clamping, e hōʻemi ana i ka paʻa paʻa a me ka manawa, a me nā mea ʻē aʻe, a e ʻike ʻia ke ʻano o ka wai i ka huahana.
4. Nā wahi noi maʻamau: ʻO nā wahi noi nui he hōʻailona a me nā mea hoʻohana, nā mea kani, nā mea hana hale, nā mea pāʻani a me nā mea hoʻokipa, a me kaʻoihana kūkulu.ʻO ka papa ahi ahi (UL V-0 a me UL 5-V), ua hana ʻia a hoʻohana nui ʻia i nā pahu TV, nā mīkini ʻoihana a me nā huahana uila.
E hoʻomau ʻia, inā makemake ʻoe e ʻike hou aku, e ʻoluʻolu e hoʻokaʻaʻike mai iā mākou.ʻO Baiyear kahi hale hana piha piha nui e hoʻohui ana i ka hana ʻana i ka mold plastic, injection molding a me ka hoʻoili metala.A i ʻole hiki iā ʻoe ke hoʻomau i ka hoʻolohe ʻana i ke kikowaena nūhou o kā mākou pūnaewele mana: www.baidasy.com, e hoʻomau mākou i ka hoʻonui ʻana i ka nūhou ʻike e pili ana i ka ʻoihana hoʻoponopono injection.
