1.What bụ PC ihe?
PC: polycarbonate, bụ nke thermoplastic material.This ihe bụ uzo, ubé edo edo, adịghị mfe ịgbanwe agba, isiike na siri ike na ọ bụ mmetụta ike bụ karịsịa nnukwu, ihe karịrị 10 ugboro na nke CR 39, top-ranked nke thermoplastic ihe. .Ezigbo nkwụsi ike na okpomọkụ, radieshon thermal, ikuku na ozone.Ọ nwere ike ịmịkọrọ ụzarị ultraviolet niile n'okpuru 385nm, na-eme ka ọ bụrụ oghere nchekwa.Na mgbakwunye na nkwụsi ike dị elu, nguzogide mmanụ, griiz na acid, mmiri na-adịghị ala ala, nkwụsi ike nke akụkụ dị elu, ọ bụ ụdị ihe nchebe gburugburu ebe obibi nke nwere ike iji ọtụtụ oge.Ọdịmma bụ nnukwu nrụgide, dị mfe ịgbawa, obere miscibility na resins ndị ọzọ, ọnụ ọgụgụ esemokwu dị elu, enweghị mmanu onwe ya.
2.The isi atụmatụ nke PC oghere:
① dị obere arọ
Igwe anya PC nwere nnukwu ike ndọda nke 1.2, ebe lenses CR-39 nwere nnukwu ike ndọda nke 1.32, ndetu refractive 1.56 nwere nnukwu ike ndọda nke 1.28, iko nwere nnukwu ike nke 2.61.N'ụzọ doro anya, n'etiti otu nkọwa na nha geometric nke oghere ahụ, lensị PC, n'ihi ntakịrị ntakịrị, na-ebelata ịdị arọ nke lenses.
② oghere dị obere
PC refractive index bụ 1.591, CR-39 (ADC) ntụzịaka ntughari bụ 1.499, Middle refractive index bụ 1.553.Nke dị elu nke ntugharị refractive bụ, ka lenses na-adị ntakịrị, ma ọzọ.E jiri ya tụnyere lenses CR39 na lenses resin ndị ọzọ, PC myopia lenses ọnụ dị ntakịrị.
③ Ezigbo nchekwa
Igwefoto PC nwere mmetụta dị oke mma nke ukwuu, nke a maara dị ka "eze plastik", enwere ike iji ya mee ihe n'ịrụpụta windo ụgbọ elu, "glass" mgbọ, ihe mkpuchi ọgba aghara na ọta.Ike mmetụta nke PC ruru 87/kg / cm2, nke karịrị nke nkedo zinc na aluminom nkedo yana okpukpu iri na abụọ karịa nke CR-39.A na-etinye lenses nke PC mere n'ala ciment ka ọ na-aga n'ihu ma ghara ịgbaji, na ọ bụ naanị lenses "anaghị agbajikwa".Ka ọ dị ugbu a, lensị PC bụ nke abụọ na nke ọ bụla n'ihe gbasara nchekwa.
Ọ na-enye ohere ịnweta ụzarị ultraviolet
Ọgwụ ọgbara ọhụrụ ekwenyela na ìhè ultraviolet bụ isi ihe na-akpata cataracts na anya.Ya mere, ihe ndị a chọrọ maka ịmịnye ọkụ ultraviolet nke anya anya na-apụtawanye ìhè.Maka anya anya m anya resin n'ozuzu, ihe ahụ n'onwe ya nwekwara akụkụ nke arụmọrụ nke absorption nke ultraviolet, mana ọ bụrụ na ịchọrọ igbochi ọkụ ultraviolet nke ọma, ị ga-etinyerịrị ụfọdụ ọkụ ọkụ ultraviolet mgbe anya m PC myopia nwere ike 100% gbochie ultraviolet. ìhè.
⑤ ezigbo ihu igwe na-eguzogide
PC bụ otu n'ime plastik injinia nwere oke ihu igwe dị mma.Dabere na data nnwale nke ịka nká n'èzí, ike tensile, haze na etiolation egosi PC agbanwebeghị nke ukwuu mgbe etinyere ya n'èzí maka afọ 3.
