ʻO ka Acrylic ka polymethyl methacrylate, i hoʻopau ʻia e like me PMMA, he ʻano polymer polymer i hana ʻia mai ka methyl methacrylate polymerization, ʻike ʻia hoʻi he aniani organik, me ke aniani kiʻekiʻe, ke kūpaʻa kiʻekiʻe o ka wā, ka paʻakikī kiʻekiʻe, ka hana maʻalahi a me nā pono ʻē aʻe. mea pani no ke aniani.
ʻO ka molecular molecular mass o PMMA ma kahi o 2 miliona, a ʻo ke kaulahao e hana ana i nā molekala he palupalu, no laila ke kiʻekiʻe ka ikaika o ka PMMA, a ʻo ka tensile a me ka hopena o ka PMMA he 7 ~ 18 mau manawa kiʻekiʻe ma mua o ke aniani maʻamau.Ke hoʻohana ʻia ʻo ia e like me ka plexiglass, inā paha i haki, ʻaʻole ia e poha e like me ke aniani maʻamau.
ʻO ka PMMA i kēia manawa ka hana optical maikaʻi loa o nā mea polymer transparent, ka transmittance o 92%, ʻoi aku ka kiʻekiʻe ma mua o ke aniani a me ka PC transmittance, a ua lilo ia i mea koʻikoʻi kumu nui o nā noi he nui.
ʻOi aku ka lua o ka pale ʻana o ka PMMA i nā plastik maʻamau, ʻoi aku ka kiʻekiʻe ma mua o ka PC maʻamau, PA a me nā plastics ʻē aʻe.Eia kekahi, hiki i ka penikala paʻakikī o PMMA ke hiki i ka 2H, ʻoi aku ka kiʻekiʻe ma mua o nā plastics maʻamau e like me PC, a maikaʻi ka pale ʻana i ka ʻili.
Ma muli o kāna mau hiʻohiʻona maikaʻi loa, ua hoʻohana nui ʻia ʻo PMMA i ka automotive, electronics a me nā mea hana home, nā mea kūʻai aku, nā kukui, nā kūkulu hale a me nā mea kūkulu hale, nā lāʻau lapaʻau a me nā ʻoihana ʻē aʻe.
Nā noi o PMMA ma ke kahua kaʻa
Ma keʻano laulā, PMMA i loko o ke kaʻa taillight, dashboard mask, waho kolamu a me nā mea hoʻonani, nā kukui o loko, rearview aniani shell a me nā māla ʻē aʻe i hoʻohana ʻia, hoʻohana nui ʻia i ka pono o ka transparency, translucent a me ka nani a me nā māla ʻē aʻe.
1, hoʻohana ʻia ʻo PMMA i nā kukui huelo kaʻa
Hoʻokaʻawale ʻia nā kukui kaʻa i nā kukui poʻo a me nā taillights, a hoʻohana ʻia nā mea aniani no nā ʻāpana e like me nā pale kukui.Hoʻohana ke kukui a me ka pale kukui noe i nā mea PC polycarbonate, no ka mea ma ke kaʻina o ka hoʻohana ʻana i ke kukui poʻo he lōʻihi ka lōʻihi o ka manawa, ʻoiai ʻoi aku ka kiʻekiʻe o ke kaʻa e holo ana ma luna o ka pale kukui.Akā ʻo ka PC i hoʻohana ʻia no nā kukui poʻomanaʻo pū kekahi i ka ʻenehana paʻakikī, ke kumu kūʻai kiʻekiʻe, maʻalahi ka ʻelemakule a me nā hemahema ʻē aʻe.
ʻO nā taillights ka mea maʻamau e huli i nā hōʻailona, nā kukui uila, haʻahaʻa ka ikaika o ka māmā, ka manawa lawelawe pōkole, no laila he haʻahaʻa haʻahaʻa nā koi kūpaʻa wela, ka hapa nui o ka hoʻohana ʻana i nā mea PMMA, PMMA transmittance 92%, ʻoi aku ka kiʻekiʻe ma mua o 90% PC, refractive index 1.492, maikaʻi ke kū i ka wā. , ʻO ka paʻakikī o ka ʻili kiʻekiʻe, ʻo ia ka mask taillight, reflector, alakaʻi māmā o ka mea kūpono.Ma muli o kona paʻakikī kiʻekiʻe, ʻoi aku ka maikaʻi o ka PMMA a hiki ke hoʻohana pololei ʻia me ka ʻole o ka pale ʻana i ka ʻili ke hoʻohana ʻia e like me nā mea aniani o waho.Loaʻa i ka PMMA māmā nā hiʻohiʻona hoʻopuehu kiʻekiʻe a maʻalahi ka hoʻokō ʻana i ka hopena kukui like ʻole, ʻo ia kekahi o nā mea nui i ka noi taillight o kēia manawa.
2, PMMA no ka dashboard mask
ʻO ka mask dashboard ka mea nui o ka pale ʻana i ka mea kani a hōʻike pololei i ka ʻikepili mea kani.Hoʻopili ʻia ka mask panel instrument, ʻoi aku ka hoʻohana ʻana o ka PMMA, me ka ʻike kiʻekiʻe, lawa ka ikaika, ʻoʻoleʻa, kūpaʻa maikaʻi, i ka radiation solar a me ka ʻenekini wela ma lalo o ke kiʻekiʻe kiʻekiʻe ʻaʻole deformation, i ka lōʻihi o ka mahana kiʻekiʻe ʻaʻole deformation. , ʻaʻole hāʻule, ʻaʻole pili i ka pololei o ka mea kani.
3, Nā kolamu waho a me nā ʻāpana ʻoki
Hoʻokaʻawale ʻia ke kolamu kaʻa i loko o ka kolamu ABC, ʻo kāna mau koi hana he ʻano kiʻekiʻe kiʻekiʻe (maʻamau ka piano ʻeleʻele), kiʻekiʻe ka pale ʻana i ka wā, kiʻekiʻe wela ke kū ʻana, ka pale ʻana i ka ʻōpala, nā mea hoʻohana maʻamau ʻo ABS + spray pena, PP + spray paint a me PMMA + ABS double extrusion. hoʻolālā, a me ka hoʻolālā PMMA paʻakikī.Ke hoʻohālikelike ʻia me ka hoʻolālā pena spray, hiki i ka PMMA ke hoʻopau i ke kaʻina hana hoʻoheheʻe, ʻoi aku ka maikaʻi o ke kaiapuni, haʻahaʻa ke kumu kūʻai, a lilo i ka papa kuhikuhi nui.
4, hoʻohana ʻia ka PMMA no nā kukui o loko
Aia nā kukui o loko i nā kukui heluhelu a me nā kukui ambiance.ʻO nā kukui heluhelu kekahi ʻāpana o ka ʻōnaehana kukui o loko o ke kaʻa, e kau mau ʻia ma mua a ma hope paha.No ka pale ʻana i ka pollution māmā, hoʻopuehu pinepine nā kukui heluhelu i ka mālamalama, me ka hoʻohana ʻana i ka matte a i ʻole ka hau PMMA a i ʻole nā hopena PC.
ʻO ke kukui Atmosphere kahi ʻano kukui e hiki ke hana i kahi lewa ʻoluʻolu a hoʻonui i ke ʻano o ke kaʻa.Hoʻokaʻawale ʻia nā ʻāpana alakaʻi māmā i hoʻohana ʻia i ke kukui ambient i ʻelua ʻano: palupalu a paʻakikī e like me ko lākou ʻano.He paʻakikī ke ʻano alakaʻi alakaʻi māmā, ʻaʻole hiki ke kulou, ma o ka hoʻoheheʻe ʻana a i ʻole extrusion molding, mea i PMMA, PC a me nā mea ʻē aʻe me ka ʻike.
5, hoʻohana ʻia ʻo PMMA i ka hale aniani ʻike hope
ʻO ka paʻi aniani ʻike hope e koi nui i ka ʻōlinolino kiʻekiʻe a me ka ʻeleʻele ʻeleʻele, ʻoiai e koi ana i ka ikaika hopena kiʻekiʻe, ka pale ʻana a me ka pale ʻana i ka wā.E like me ke ʻano o ka pūpū aniani i ʻāwili ʻia, maʻalahi ka hana ʻana i ke koʻikoʻi, no laila pono ke kiʻekiʻe o ka hana machining a me ka paʻakikī.ʻO ka papahana maʻamau ka ABS spray peʻa, akā he koʻikoʻi ke kaʻina hana pollution, he nui ke kaʻina hana, hiki i ka hoʻohana ʻana i ka PMMA scheme ke hoʻokō i ka spraying manuahi, maʻamau maʻaneʻi e hoʻohana i ka pae paʻakikī o nā mea PMMA, e hoʻokō i ka hoʻāʻo outline i ka hoʻokolohua hāʻule a me nā mea ʻē aʻe. nā papahana.
ʻO ka mea i luna nei ka hoʻohana maʻamau o PMMA i ke kahua automotive, pili nui i ka optics a i ʻole nā hiʻohiʻona, hoʻohui ʻo PMMA i nā mea hou aʻe i ke kahua automotive.
