Njirimara kemịkalụ:

Polycarbonatebụ ihe amorphous, enweghị ụtọ, odorless, na-abụghị egbu egbu transperent thermoplastic polymer, nwere magburu onwe n'ibu, thermal na eletriki Njirimara, karịsịa mmetụta nguzogide, ezi ike, creep bụ obere, ngwaahịa size kwụsiri ike. Ike mmetụta ya nke 44kj / mz, ike tensile> 60MPa. polycarbonate okpomọkụ na-eguzogide dị mma, ike ga-eji ruo ogologo oge na - 60 ~ 120 ℃, okpomọkụ deflection okpomọkụ 130 ~ 140 ℃, iko mgbanwe okpomọkụ nke 145 ~ 150 ℃, ọ dịghị doro anya na-agbaze ebe, na 220 ~ 230 ℃ bụ gbazee ala. . Thermal ire ere okpomọkụ> 310 ℃. N'ihi nkwụsi ike nke yinye molekụla, viscosity ya gbazere dị elu karịa nke thermoplastics izugbe.

Ngwa:

Polycarbonates bụ plastik a na-ejikarị eme ihe na ụlọ ọrụ ọgbara ọhụrụ nwere ezigbo okpomọkụ na nguzogide mmetụta. Nke a plastic dị mma karịsịa na-arụ ọrụ na ndị ọzọ ot nkọwa usoro (injection ịkpụzi, extrusion n'ime tubes ma ọ bụ cylinders na thermoforming). A na-ejikwa ya mgbe achọrọ nghọta anya, na-enwe ihe karịrị 80% nnyefe ruo 1560-nm (oke infrared dị mkpụmkpụ). Ọ nwere ihe mgbochi kemịkalụ na-agbanwe agbanwe, na-eguzogide ọgwụ na-egbochi acid na alcohols. Ọ na-eguzogide ọgwụ na-adịghị mma megide ketones, halogens na acid gbanyere mkpọrọgwụ. Ihe ọghọm dị na ya na polycarbonates bụ obere iko mgbanwe okpomọkụ (Tg> 40 Celsius C), mana a ka na-ejikarị ya dị ka ihe dị ọnụ ala na sistemụ microfluidic yana kwa oyi akwa.
