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.Aʻe ka ʻatikala ʻelua.
(3).SA (SAN–styrene-acrylonitrile copolymer/Dali glue)
1. ʻO ka hana a SA:
Nā Waiwai Kemika a me ke Kino: ʻO SA kahi mea paʻakikī a maopopo ʻaʻole kūpono i ka pohā o ke kaumaha o loko.ʻOi aku ka ʻike kiʻekiʻe, kona wela palupalu a me ka ikaika hopena ma mua o PS.ʻO ka ʻāpana styrene ka SA paʻakikī, ʻike a maʻalahi hoʻi e hana;ʻO ka mea acrylonitrile ka mea e hana ai i ka SA me ka paʻa a me ka wela.Loaʻa i ka SA ka mana haʻahaʻa haʻahaʻa ikaika, ke kūpaʻa hopena kemika, ke kūpaʻa deformation thermal a me ke kūpaʻa geometric.
ʻO ka hoʻohui ʻana i nā mea hoʻohui aniani fiber i SA hiki ke hoʻonui i ka ikaika a me ke kūpaʻa deformation thermal, a e hōʻemi i ka coefficient hoʻonui thermal.ʻO ka mahana hoʻonāwaliwali o Vicat o SA ma kahi o 110°C.ʻO ka mahana deflection ma lalo o ka ukana ma kahi o 100C, a ʻo ka shrinkage o SA ma kahi o 0.3 ~ 0.7%.
2. Nā hiʻohiʻona o ke kaʻina hana o SA:
ʻO ka mahana hana o SA ka maʻamau 200-250 °C.He mea maʻalahi ke komo i ka makū a pono e hoʻomaloʻo ʻia no hoʻokahi hola ma mua o ka hana ʻana.ʻOi aku ka maikaʻi o ka wai ma mua o ka PS, no laila ʻoi aku ka kiʻekiʻe o ke kaomi injection (ke kaomi injection: 350 ~ 1300bar).ʻO ka wikiwiki hoʻoheheʻe: ʻōlelo ʻia ke kiʻekiʻe kiʻekiʻe.ʻOi aku ka maikaʻi o ka mālama ʻana i ka mahana ma 45-75 ℃.Ka Hoʻomaloʻo ʻana: Loaʻa iā SA kekahi mau waiwai hygroscopic inā mālama pono ʻole ʻia.
ʻO nā kūlana maloʻo i ʻōlelo ʻia he 80 ° C, 2 ~ 4 mau hola.Ka wela hehee: 200~270 ℃.Inā hoʻohana ʻia nā huahana pā mānoanoa, hiki ke hoʻohana ʻia nā mahana heheʻe ma lalo o ka palena haʻahaʻa.No nā mea i hoʻoikaika ʻia, ʻaʻole pono ka mahana o ka mold ma mua o 60 ° C.Pono e hoʻolālā maikaʻi ʻia ka ʻōnaehana hoʻoluʻu, no ka mea, e pili pono ana ka mahana o ka mold i ke ʻano, ka emi ʻana a me ka piko o ka ʻāpana.Nā mea holo a me nā ʻīpuka: Hiki ke hoʻohana ʻia nā ʻīpuka maʻamau a pau.Pono ka nui o ka puka e pale i nā kaha, nā kiko a me nā hakahaka.
3. Laulā noi maʻamau:
ʻO ka uila (nā kumu, nā hale, a me nā mea'ē aʻe), nā mea kūʻai i kēlā me kēia lā (nā meahana lumi kuke, nā pahu friji, nā kumu TV, nā pahu cassette, a me nā mea'ē aʻe). nā pahi, a me nā mea'ē aʻe) a me nā mea'ē aʻe).
ʻO nā huahana lapaʻau (nā syringes, nā paipu hoʻoheheʻe koko, nā mea hoʻoheheʻe renal a me nā reactors).ʻO nā mea hoʻopili (nā pahu hoʻonaninani, nā lima lipstick, nā ʻōmole pāpale mascara, nā pāpale, nā mea hoʻoheheʻe pāpale a me nā nozzles, a me nā mea ʻē aʻe), nā huahana kūikawā (nā hale māmā hiki ke hoʻokuʻu ʻia, nā kumu palaki a me nā bristles, nā mea lawaiʻa, nā niho niho, nā lima pulupulu niho, nā mea paʻa peni, nā nozzles mea kani. a me nā monofilaments kuhikuhi), etc.
(4).ABS
1. ABS hana:
Hoʻohui ʻia ʻo ABS mai ʻekolu monomers kemika, acrylonitrile, butadiene a me styrene.(He ʻokoʻa nā waiwai o kēlā me kēia monomer: ʻo ka acrylonitrile ka ikaika kiʻekiʻe, ke kūpaʻa wela a me ke kūpaʻa kemika; ʻo ka butadiene ka paʻakikī a me ka hopena o ka hopena; ʻo ka styrene he hana maʻalahi, hoʻopau kiʻekiʻe a me ka ikaika kiʻekiʻe. ʻĀpana styrene-acrylonitrile mau a me kahi ʻāpana polybutadiene rubber i hoʻopuehu ʻia.)
Mai ka manaʻo morphological, he mea amorphous ka ABS me ka ikaika mechanical kiʻekiʻe a me nā waiwai piha maikaʻi o "ka paʻakikī, ka paʻakikī a me ke kila".He polimer amorphous.ʻO ka ABS he plastic engineering maʻamau me nā ʻano ʻano like ʻole a me ka nui o ka hoʻohana ʻana.Kapa ʻia ʻo ia ʻo "plastic-purpose plastic" (kapa ʻia ʻo MBS transparent ABS).ʻOi aku ke kaumaha o ka wai), haʻahaʻa haʻahaʻa (0.60%), paʻa ke ʻano, a maʻalahi hoʻi e hana a hana.
ʻO nā waiwai o ABS e hilinaʻi nui ʻia i ka ratio o nā monomers ʻekolu a me ke ʻano molekala i nā pae ʻelua.ʻAe kēia i ka loli nui i ka hoʻolālā huahana, a ua hopena i nā haneli o nā mea ABS maikaʻi like ʻole ma ka mākeke.Hāʻawi kēia mau mea waiwai ʻokoʻa i nā waiwai like ʻole e like me ke kūpaʻa ʻana i ka hopena kiʻekiʻe, haʻahaʻa a kiʻekiʻe a me ke kiʻekiʻe kiʻekiʻe o nā waiwai wili, a me nā mea ʻē aʻe.
ʻO ABS he māmā melemele granular a beaded opaque resin, non-toxic, odorless, haʻahaʻa wai absorption, me ka maikaʻi piha physical a me mechanical waiwai, e like me ka maikaʻi uila waiwai, aahu ke kūpale, dimensional paʻa, kemika kū'ē a me ka ili olinolino, etc. e hana a hoʻohua.ʻO ka hemahema ka pale ʻana i ka wā, ka pale wela maikaʻi ʻole, a me ka flammability.
2.Process hiʻona o ABS
2.1 He kiʻekiʻe ka hygroscopicity ABS a me ka ʻike wai.Pono e hoʻomaloʻo piha ʻia a preheated ma mua o ka hoʻoheheʻe ʻana (ma ka liʻiliʻi o 2 mau hola ma 80 ~ 90C), a pono e hoʻomalu ʻia ka ʻike ma lalo o 0.03%.
2.2 ʻAʻole maʻalahi ka hoʻoheheʻe ʻana o ka resin ABS i ka mahana (ʻokoʻa mai nā resins amorphous ʻē aʻe).
ʻOiai ʻoi aku ka kiʻekiʻe o ka mahana injection o ABS ma mua o ka PS, ʻaʻole hiki iā ia ke loaʻa kahi ākea hoʻomehana e like me PS, a ʻaʻole hiki ke hoʻohana i ka hoʻomehana makapō e hōʻemi i kona viscosity.Hiki ke hoʻonui ʻia ma ka hoʻonui ʻana i ka wikiwiki o ka screw a i ʻole ke kaomi injection e hoʻomaikaʻi i kona wai.ʻO ka mahana hana maʻamau he 190-235 ℃.
2.3 ʻO ka melt viscosity o ABS he mea waena, ʻoi aku ka kiʻekiʻe ma mua o ka PS, HIPS, a me AS, a koi ʻia ke kiʻekiʻe o ka injection (500 ~ 1000bar).
2.4 Hoʻohana nā mea ABS i ka wikiwiki a me ka wikiwiki a me nā wikiwiki injection ʻē aʻe e loaʻa ai nā hopena maikaʻi aʻe.(Inā ʻaʻole paʻakikī ke ʻano a ʻo nā ʻāpana ʻāpana ʻeleʻele e koi i ka wikiwiki o ka injection), ʻoi aku ka maikaʻi o ke kūlana nozzle o ka huahana i nā ea.
2.5 He kiʻekiʻe ka mahana hoʻoheheʻe ʻana o ABS, a ua hoʻoponopono ʻia kona ʻano wela ma 25-70 °C.
I ka hana ʻana i nā huahana ʻoi aku ka nui, ʻoi aku ka nui o ka mahana o ka mold paʻa (mua o mua) ma kahi o 5 ° C kiʻekiʻe ma mua o ka movable movable (hope mold).(E hoʻopilikia ka wela o ka polū i ka pau ʻana o nā ʻāpana plastik, ʻo ka haʻahaʻa haʻahaʻa e hopena i ka hopena haʻahaʻa)
2.6 ʻAʻole pono ʻo ABS e noho i loko o ka pahu wela kiʻekiʻe no ka lōʻihi loa (e emi iho ma mua o 30 mau minuke), i ʻole e pohō a huli melemele.
3. Laulā hoʻohana maʻamau: nā kaʻa (nā dashboards, nā mea paʻa paʻa, nā uhi huila, nā pahu aniani, a me nā mea ʻē aʻe), nā pahu hau, nā mea hana ikaika kiʻekiʻe (nā lauoho maloʻo, blenders, meaʻai meaʻai, lawn mowers, etc.), kelepona pahu, typewriter keyboards , nā kaʻa leʻaleʻa e like me nā kaʻa kolepa a me nā jet ski.
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.
