Polycarbonate (PC no ka pōkole, kona inoa mai loko mai o kona CO3 pūʻulu. ) he polymer i loaʻa nā hui carbonate i loko o ke kaulahao mole, hiki ke hoʻokaʻawale ʻia i nā ʻano aliphatic, aromatic, a me aliphatic-aromatic e like me ke ʻano o ka hui ester. Ma waena o lākou, he haʻahaʻa ka waiwai mechanical o ka polycarbonate aliphatic a me ka aliphatic-aromatic, no laila e kaupalena ana i kāna noi ʻana i nā plastics engineering. I kēia manawa, hana ʻia ka polycarbonate aromatic wale nō. Ma muli o nā hiʻohiʻona o ka polycarbonate, ua lilo ia i mea wikiwiki e ulu ana i ka plastik ʻenekinia ma waena o nā plastic engineering nui ʻelima.
Nā Pono Kemika
Kūleʻa ka Polycarbonate i nā ʻakika nāwaliwali, nā kumu nāwaliwali a me nā aila kūʻole. ʻO ka PC kahi polimer amorphous aniani ʻaʻohe kala me nā waiwai optical maikaʻi. He kiʻekiʻe ka ikaika o ka resin molecular weight PC, cantilever beam notch impact strength of 600 ~ 900J/m, wela deflection temperature of unfilled grade is about 130°C, glass fiber reinforced to increase this value by 10°C. Hiki i ka modulus bending o PC ke hiki i 2400 MPa a i ʻole, hiki ke hana ʻia ka resin i nā huahana paʻa nui.

Polycarbonate: Density: 1.18-1.22 g / cm^3 Hoʻonui laina: 3.8 × 10 ^ -5 cm / ° C Ka wela wela: 135 ° C Haʻahaʻa haʻahaʻa -45 ° C. ʻO ka polycarbonate he kala ʻole a ʻaʻole hoʻi, ʻaʻohe wela, kūpaʻa i ka hopena, ka pae BI pale ahi, a loaʻa iā ia nā waiwai mechanical maikaʻi i nā mahana hoʻohana maʻamau. Hoʻohālikelike ʻia me ka hana kokoke i ka polymethyl methacrylate, polycarbonate ka hopena maikaʻi o ka hopena, kiʻekiʻe refractive index, maikaʻi ka hana ʻana, a me ka UL94 V-0 pae hoʻopaʻa ahi me ka ʻole o nā mea hoʻohui.
Nā pono nui

1. Ka ikaika kiʻekiʻe a me ka elasticity, ka ikaika hopena kiʻekiʻe, ka laulā ākea ākea;
2. Mākaʻikaʻi kiʻekiʻe a me ke kala manuahi;
3. Haʻahaʻa shrinkage rate a me ka maikai dimensional paʻa.
4. Kū'ē maikaʻi i ka luhi;
5. Kūleʻa maikaʻi i ka wā;
6. ʻO nā hiʻohiʻona uila maikaʻi loa.
