Ua noʻonoʻo paha ʻoe pehea i hana ʻia ai kēlā mau huahana plastik maʻemaʻe me ka pololei a me ka maopopo? ʻAe, aia ka pane i ka honua hoihoi o ka hoʻoheheʻe ʻana i ka PMMA. Ma kēia moʻomanaʻo, e hoʻomohala mākou i ke kaʻina hana hou o ka PMMA injection molding, e ʻimi ana pehea i hoʻololi ai i ka ʻoihana hana me kāna mau pono a me nā noi.

No laila, e hoʻopaʻa i ka wā e lawe ai mākou iā ʻoe i kahi huakaʻi ma waena o ke aupuni o PMMA a e ʻike i ke ʻano o kēia mea maʻalahi i ka wā e hiki mai ana o ka hana ʻana i ka plastic.

He aha ka PMMA？

ʻO ka polymethyl methacrylate, i kapa ʻia ʻo PMMA, he polymer, ʻike ʻia hoʻi he acrylic a i ʻole plexiglass.

ʻO ka waika Acrylic a me kāna polymerization ʻoluʻolu o nā polymers i loaʻa i hui pū ʻia i kapa ʻia ʻo ka vinega kumulāʻau acrylic, nā plastics pili i hui pū ʻia he polyacrylic acid plastics, nona ka polymethyl methacrylate i hoʻohana nui ʻia.

Na Mea Pono PMMA

Ma keʻano he thermoplastic koʻikoʻi i hoʻomohala muaʻia, ua loaʻa i ka PMMA nā mea maikaʻi o ke kiʻekiʻe kiʻekiʻe, ke kumu kūʻai haʻahaʻa, ka hana mechanical maʻalahi, a me nā mea'ē aʻe.

ʻAʻole waihoʻoluʻu a ʻike ʻia, ka māmā o ka hoʻouna ʻana o 90% -92%, paʻakikī, ʻoi aku ma mua o 10 mau manawa ʻoi aku ka nui ma mua o ke aniani silica.

Optics maikaʻi, insulation, processability and weather resistance.

Hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe kūlohelohe e like me carbon tetrachloride, benzene, toluene, dichloroethane, trichloromethane a me acetone.

Hōʻike ia i ke aniani kiʻekiʻe a me ka ʻōlinolino, ke kūpaʻa wela maikaʻi, a me ka paʻakikī, ka paʻakikī, nā hiʻohiʻona rigidity, ka wela distortion wela o 80 ℃, ka ikaika kulou o 110Mpa.

Density 1.15 - 1.19 g/cm³, ka wela deformation 76-116 ℃, hoʻoheheʻe ʻia 0.2-0.8%.

ʻO ka hoʻonui laina laina 0.00005-0.00009 / ° C, ka wela distortion wela 68-69 ° C (74-107 ° C) .He aha ka PMMA Injection Molding?

ʻO ka poli (methyl mеthacrylatе), i ʻike nui ʻia ʻo PMMA, he māmā māmā a me ka transparеnt thermoplastic polymеr i loaʻa i ka kaulana i nā ʻoihana like ʻole. ʻO kona hiki ke hoʻohālike i ke aniani ʻoiai he māmā a paʻa i ka hopena e lilo ia i koho kūpono no nā noi he nui.

ʻO ka hoʻoheheʻe ʻana i ka PMMA he kaʻina hana hana kūpono a kūpono hoʻi e hoʻokomo i ka PMMA i hoʻoheheʻe ʻia i loko o nā mole i hoʻopili ʻia ma lalo o ke kaomi kiʻekiʻe, e hāʻawi ana i kahi ākea ākea o nā huahana me ka maopopo a me nā pono optical.

No ke aha i hoʻohana nui ʻia ai ka PMMA a i ʻole Acrylic no ka hoʻoheheʻe ʻana?

ʻO ka Polymethylmethacrylate (PMMA) a i ʻole ka acrylic kahi thermoplastic ikaika, akaka, kiʻekiʻe-transparency me ka mālamalama optical maikaʻi loa i hoʻohana pinepine ʻia e like me ke aniani.

Ke hoʻohālikelike ʻia me ka hoʻoheheʻe ʻana i ka polycarbonate, ʻoi aku ka liʻiliʻi o ka hoʻoheheʻe ʻana o PMMA a hiki ke hoʻoheheʻe maʻamau i nā acrylics. ʻO ka hopena, makemake ʻia nā mea PMMA e ka ʻoihana hana hoʻohui no ka prototyping.

I ka manawa like, loaʻa i ka acrylics ka ikaika tensile kiʻekiʻe, hiki ke kūpaʻa i nā ukana, ʻaʻole e komo i nā mea ʻala, a hiki ke mālama i ka hoʻomanawanui i ka wā o ke kaʻina hana hoʻoheheʻe.

I ka lā a me ka ua, kūpaʻa ka PMMA i nā kukuna UV a, i ka wā e hoʻopili ai me ka wai, paʻa paʻa a ʻaʻole hoʻokuʻu i ka bisphenol A (BPA), kahi kemika i loaʻa i loko o ka nui o nā plastics e hoʻopilikia maikaʻi i ke olakino kanaka, kūpono ia no nā noi waho.

Ma ke ʻano holoʻokoʻa, ʻokoʻa ka launa ʻana ma waena o ka PMMA a me nā ʻenehana hoʻoheheʻe injection, e hāʻawi ana i kahi hopena hoʻoheheʻe hoʻokele waiwai i ka wā e hana ana i nā huahana kiʻekiʻe.

Nā Kūlana o ka PMMA Injection Molding Processing

Ma ke kaʻina hana hoʻoheheʻe PMMA, hoʻomehana ʻia ka pauka a i ʻole granules i kahi ʻano hoʻoheheʻe ʻia a laila hoʻokomo ʻia i loko o kahi ʻōpala ma lalo o ke kaomi kiʻekiʻe. Ma hope o ka ʻoluʻolu a me ka hoʻonohonoho ʻana, hoʻoneʻe ʻia ka mold, ka hopena i nā huahana hoʻoheheʻe PMMA maʻamau.

 

ʻO nā pono o ka PMMA Injection Molding

Hāʻawi ʻo PMMA injеction molding i nā pono he nui, e lilo ia i mea i ʻimi nui ʻia no nā noi like ʻole. E ʻimi kākou i kēia mau pōmaikaʻi i ka ʻike hou aku:

●Mālamalama Optical

ʻO kekahi o nā hiʻohiʻona maikaʻi loa o ka PMMA ʻo ia ka ʻike ʻike ʻokoʻa. Ke hoʻohālikelike ʻia me nā mea ʻē aʻe, hāʻawi ʻo PMMA i ke aniani ʻike ʻole ʻole, kokoke like me ke aniani akā ʻaʻohe kaumaha. ʻO kēia hiʻohiʻona ka mea i koho maikaʻi loa no nā huahana kahi mea koʻikoʻi ka ʻike maka.

ʻO nā aniani paha, nā lens kāmela, a i ʻole nā ​​uhi kukui automotive, e hōʻoia ʻo PMMA i ka ʻike kiʻekiʻe, e hoʻonui ana i ka ʻike a me nā aesthetics o ka huahana.

●Māmā a me ka Impact-Resistant

Hoʻokaʻawale ke ʻano māmā o PMMA mai ke aniani kuʻuna.

ʻO kēia waiwai ka mea i makemake nui ʻia i nā noi kahi e pono ai ke kaumaha, e like me nā mea aerospace a me nā mea lapaʻau. Hoʻohui ʻia, ʻo kāna mau waiwai pale i ka hopena e hōʻemi i ka pilikia o ka haki ʻana i nā hopena ʻino, e hoʻomaikaʻi i ka palekana i nā ʻano hiʻohiʻona.

●ʻO UV a me Wеathеr Resistance

ʻIke ʻia ʻo PMMA no kāna UV maikaʻi a me ka pale ʻana i ka wеather, kūpono ia no nā noi i loko a me waho. Ke hōʻike ʻia i ka lā, ʻaʻole e hoʻoheheʻe ʻia nā huahana PMMA i ka wā lōʻihi, e hōʻoiaʻiʻo ana i ka loli ʻole o ko lākou helehelena a mālama i ko lākou lōʻihi.

Hoʻohana kēia ʻano maikaʻi i nā hōʻailona waho, nā aniani aniani, a me nā uhi kukui automotive.

●Vеrsatility ma Dеsign

Hāʻawi ka PMMA injection molding i ka hiki ke hoʻolālā ʻia, e ʻae ana i nā mea hana e hana maʻalahi i nā ʻano paʻakikī a paʻakikī.

Hiki i nā mea hoʻolālā ke hoʻokuke i nā palena o ka noʻonoʻo, hana i nā huahana plastic innovative e hoʻokō i nā pono kikoʻī.

Hiki i kēia maʻalahi ke hoʻohana i ka PMMA i kahi ʻano nui o nā mea, mai nā mea hale maʻalahi a i nā mea lapaʻau maʻalahi, e wehe ana i kahi honua o nā mea hiki no nā ʻoihana like ʻole.

Nā noi o ka PMMA Injеction Molding

● Nā Pepa Transparеnt a me ke kala

ʻImi nui ʻia nā pepa PMMA no nā noi e koi ana i ka ʻike a me ka pale ʻana i ka ʻino. ʻO nā ʻoihana e like me ke kālai ʻana a me ke kūkulu ʻana e hoʻohana ana i nā pepa PMMA no nā skylights a me nā glazing architectural, e ʻae ana i ka mālamalama maoli e hoʻomālamalama i loko i ka wā e hōʻoiaʻiʻo ana i ka lōʻihi a me ka pale UV.

Hoʻohui ʻia, hoʻohana ʻia nā pepa PMMA i nā hōʻailona e hana i nā hōʻike ʻike maka me ka maopopo ʻole.

Eia kekahi, loaʻa nā pepa PMMA i nā kala like ʻole, e hāʻawi ana i nā mea hoʻolālā me ka maʻalahi e hoʻokomo i nā mea nani a me nā hiʻohiʻona ʻike i kā lākou papahana.

● ʻOihana Automotive

Ke hilinaʻi nui nei ka ʻāpana kaʻa i ka hoʻoheheʻe ʻana i ka PMMA e hana i nā ʻano mea like e hāʻawi i ka palekana a me ke ʻano. ʻO ka PMMA maikaʻi loa no ka hana ʻana i nā kukui kukui, e hōʻoiaʻiʻo ana i ka mālamalama a me ka mālamalama no ka hoʻonui ʻana i ka ʻike alanui.

Pēlā nō, pōmaikaʻi nā kukui huelo mai ka ʻike ʻana o ka PMMA, e hāʻawi ana i nā aesthetics holoʻokoʻa o ke kaʻa. Hoʻohui ʻia, hoʻohana ʻia ʻo PMMA no nā panela mea kani, e hāʻawi ana i kahi hopena māmā a me ka nānā ʻana i nā mea o loko o ke kaʻa.

● Nā Mea Lapaʻau

He kuleana koʻikoʻi ka PMMA ma ke kahua lapaʻau, kahi i nui ai ka pololei a me ka biocompatibility. Intravenous paipu, no ka laʻana, pōmaikaʻi mai ka PMMA'ālohilohi, e 'ae i ke kauka 'oihana e nānā pono kahe kahe.

Hoʻohana ʻia nā cuvetts PMMA no ka hoʻāʻo ʻana i ke koko, e hāʻawi ana i kahi ʻike maopopo o ka laʻana no ka nānā pono ʻana. Eia kekahi, ʻo nā mea niho PMMA, e like me nā niho niho a me nā alignеrs māmā, hāʻawi i nā mea maʻi me ka ʻoluʻolu a me ka nānā ʻana i nā hopena no ko lākou olakino waha.

• Nā ʻElectronics a me nā Papa Hōʻike

Ke hilinaʻi nei ka ʻoihana uila i ka ʻike ʻike ʻokoʻa o ka PMMA e hana i nā paneli hōʻike no nā kelepona akamai, papa, a me nā mea nānā kamepiula. Mālama ka ʻike o ka mea i nā kiʻi ʻoniʻoni a me ka ʻike, hoʻonui i ka ʻike mea hoʻohana.

Hoʻohana pū ʻia nā aniani PMMA i nā kāmela a me nā mea uila, e hōʻoia ana i ka pono o nā kiʻi ma o ka hōʻemi ʻana i nā distortions optical.

●Household and Consumе Goods

ʻO ka māmā, ka lōʻihi, a me ka maʻalahi o ka PMMA e lilo ia i koho kaulana no nā mea hale a me nā mea kūʻai aku.

Kitchеnware, e like me nā ipu meaʻai akaka, pōmaikaʻi mai ka mālamalama o PMMA, e ʻae ana i nā mea hoʻohana e ʻike maʻalahi i nā ʻike. Hoʻohui ʻia, hoʻohana ʻia ʻo PMMA e hana i nā pahu waihona, e hāʻawi ana i kahi hopena lōʻihi a lōʻihi no ka hoʻonohonoho ʻana i nā mea hale.

Eia kekahi, ʻo ka PMMA hiʻohiʻona hiʻohiʻona e lilo ia i mea makemake no nā huahana decorative, e hoʻohui i kahi paʻi nani i nā mea hale like ʻole.
