Polycarbonate (PC)

Hoʻohana nui ʻia i ka ʻoihana ʻaha aniani, ʻoihana kaʻa a me nā uila, ʻoihana uila, ukali ʻia e nā ʻāpana mīkini hana, CD, ʻūlū, kamepiula a me nā pono keʻena ʻē aʻe, mālama olakino a me nā lawelawe olakino, kiʻi ʻoniʻoni, leʻaleʻa a me nā pono pale.

ʻO Polycarbonate PC kahi polyester carbonated linear a kahi i hoʻonohonoho ʻia ai nā hui kalapona me nā hui ʻē aʻe e ʻala, aliphatic, a i ʻole ʻelua. Ke hoʻohana ʻia nei ʻo polycarbonate ʻAromatic ma ke ʻano he plastics ʻenehana.

Hana wela

Loaʻa nā huahana PC puna wela i ke kūpaʻa wela maikaʻi, hiki ke hoʻohana i ka mahana lōʻihi i 130â "ƒ, a maikaʻi ke anuanu maikaʻi, ʻoluʻolu wela o -100â" ƒ. ʻAʻohe kiko o ka hoʻoheheʻe o PC, ma ka 220-230â "ƒ i hoʻomoʻa ʻia, no ka nui o ka paʻa o ke kaulahao molekole, ʻoi aku ka kiʻekiʻe o ka viscosity hoʻoheheʻe ma mua o kekahi thermoplastics ʻē aʻe.

Nā pono mīkini o

ʻO nā huahana punahelu PC he maikaʻi loa ke kino a me ka mechanical, ʻoi aku ka maikaʻi o ka hopena, kūpaʻa dimensional maikaʻi, hiki ke hoʻomau i ka ikaika mechanical kiʻekiʻe i ka mahana haʻahaʻa; Eia nō naʻe, haʻahaʻa ka ikaika o ka luhi, maʻalahi ka haʻihaʻi pilikia, a me ka ʻaʻahu. maikaʻi ʻole ke kūpaʻa. ʻAʻole kala a hoʻomaʻemaʻe ʻia ka PC Unmodified, a maikaʻi ke ʻike ʻia ka transmissibility malamalama.

Nā waiwai kemika

Kūpaʻa nā huahana punahe PC i ka waikawa a me ka media aila, akā ʻaʻole kūpale alkali, hiki ke hoʻoheheʻe ʻia i ka hanauna mālamalama. He kūpaʻa hydrolysis maikaʻi ka PC, akā maʻalahi ka hoʻohuʻu wā lōʻihi i ka wai paila e hana i ka hydrolysis a me ka haki, ʻaʻole hiki ke hoʻohana ʻia i kiʻekiʻe kiʻekiʻe -hiki i nā huahana mahu. Hiki i ka PC i kekahi mau mea hoʻoheheʻe kūlohelohe, ʻoiai hiki ke kūʻē i nā waiwaliwali nāwaliwali, nā wai wai wai wai wai wai wai, akā hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe i loko o ka chlorine.

Nā memo no ka hoʻohana:

Maʻalahi e hoʻokuʻu i ka lāʻau ʻona bisphenol A, kahi mea hōʻino i ke kino o ke kanaka. Mai hoʻohana ia mea i ka wela a i ʻole ka lā kūpono.
