Hoʻopauʻia ka Polycarbonate Sheet e like me ka papa PC, i hanaʻia me ka polycarbonate polymer.Ua hanaʻia me keʻano kūlana kiʻekiʻe a me kaʻenehana extrusion hou. mea kūkulu hale no ka plexiglass.ʻOi aku ka maikaʻi o ka papa PC ma mua o ke aniani laminated, ke aniani ʻoluʻolu, ke aniani Insulating, a pēlā aku.
Nā mea hoʻohui anti-ultraviolet
ʻO ka mea maʻamau, ʻelua mau ʻano resins i kūʻai ʻia e ka papa hana papa, hoʻokahi ka resin PC maʻamau,
ʻO ka mea ʻē aʻe he PC resin i loaʻa nā mea hoʻohui anti-ultraviolet.No laila, ʻoi aku ka nui o nā mea hoʻohui anti-ultraviolet i koho ʻia e like me kēia mau ʻāpana:
(1) ʻO nā esters salicylic acid, e like me ka p-tert-butylphenyl salicylate (TBS).
(2) Benzophenones, e like me 2-hydroxy-4-methoxybenzophenone (UV-9);
2-hydroxy-4-methoxy-2′-carboxybenzophenone (UV-207);
2-Hydroxy-4-n-octyloxybenzophenone (UV-531).
(3) Benzotriazoles e like me 2-(2′-hydroxy) -3,7,5′-di-tert-butylphenylbenzotriazole (UV-320);
2-(2′-hydroxy-5′-tert-octylphenyl) benzotriazole (uV-5411) a me nā mea like.
He maʻalahi loa ka papa PC e hoʻopuka i ke koʻikoʻi o loko,
Hiki ke ho'āʻo ʻia inā he koʻikoʻi ko loko o ka papa e ka hoʻoheheʻe ʻana i ka carbon tetrachloride a me ke kukui polarized.
Hiki ke hoʻopau ʻia ke koʻikoʻi o loko o ka lau e ka annealing.
