Kedu ihe bụ polycarbonate?
Polycarbonate (PC) bụ ihe eji eme ihe n'ọtụtụ ebe na ụlọ ọrụ kemịkalụ ma bụrụ otu n'ime ihe ndị a ma ama n'ọtụtụ ụlọ ọrụ n'ihi njirimara anụ ahụ na kemịkal pụrụ iche. N'isiokwu a, anyị ga-enyocha n'ụzọ zuru ezu ihe mejupụtara na ihe onwunwe nke Polycarbonate na ọtụtụ ngwa ya.
1. Ihe mejupụtara kemịkalụ na nhazi nke polycarbonate
Polycarbonate bụ klas nke bisphenol A (BPA) na otu carbonate site na mmeghachi omume polycondensation nke polymer linear mepụtara. Ya molekụla yinye nwere ọnụ ọgụgụ buru ibu nke carbonate otu (-O-CO-O-), a Ọdịdị na-enye polycarbonate ihe magburu onwe okpomọkụ na-eguzogide, nghọta na mmetụta iguzogide. Nkwụsi ike kemịkalụ nke polycarbonate na-enyere ya aka ịnọgide na-enwe ihe onwunwe ya na-agbanweghị na gburugburu ebe dị oke egwu, na-eme ka ọ bụrụ ihe na-adịgide adịgide.
2. Ihe ndị dị mkpa nke polycarbonate
A maara ihe onwunwe polycarbonate maka njirimara anụ ahụ dị elu. Ọ nwere mmetụta dị elu nke ukwuu, ugboro 250 nke iko nkịtị, nke na-eme ka polycarbonate na-ewu ewu na ngwa ndị chọrọ ike dị elu na nguzogide mmetụta. Polycarbonate nwere ezigbo nguzogide okpomọkụ, na-adịgide adịgide site na -40 ° C ruo 120 Celsius, nke na-enye ya ohere ịrụ ọrụ nke ọma na gburugburu ebe okpomọkụ dị elu. Polycarbonate nwekwara ezigbo nghọta nke anya, na-ebufe ihe karịrị pasent 90 nke ìhè a na-ahụ anya, ya mere a na-ejikarị ya eme ihe n'ichepụta anya anya anya na ihe mkpuchi.
3. Ngwa mpaghara nke polycarbonate
N'ihi njirimara pụrụ iche nke ihe polycarbonate, a na-eji ya eme ihe n'ọtụtụ ụlọ ọrụ. N'ime ụlọ ọrụ mmepụta ihe, a na-ejikarị polycarbonate eme ihe ọkụ ọkụ, ihe mkpuchi ụlọ na ihe mkpuchi. Nguzogide mmetụta ya dị oke mma na nghọta na-eme ka ọ dị mkpa na mpaghara ndị a. Na mpaghara eletriki na eletriki, a na-eji polycarbonate eme ihe eletriki eletrik, ụlọ ngwa ụlọ na batrị batrị n'ihi nguzogide okpomọkụ ya na ihe mkpuchi ọkụ eletrik. A na-ejikwa polycarbonate eme ihe n'ọtụtụ ebe na ụlọ ọrụ ụgbọ ala, tumadi maka oriọna oriọna, ogwe ngwá ọrụ na windo. Nke kachasị mkpa, a na-ejikwa polycarbonate eme ihe n'ọtụtụ ebe n'ọhịa nke ngwaọrụ ahụike, dị ka sirinji, akụrụngwa dialysis na ngwá ọrụ ịwa ahụ, wdg. Ngwa ndị a na-ekele maka enweghị nsị na bioacompatibility nke ihe polycarbonate.
4. Polycarbonate dị mma na gburugburu ebe obibi
Ọ bụ ezie na polycarbonate bụ ihe na-adịgide adịgide ma na-agbanwe agbanwe, bisphenol A (BPA) nke na-etinye aka na mmepụta ya akpatala ụfọdụ esemokwu gburugburu ebe obibi. Ka teknụzụ na-aga n'ihu, a na-emepụta ọtụtụ ngwaahịa polycarbonate na-emetụta gburugburu ebe obibi nke na-ebelata mmetụta na gburugburu ebe obibi. Ntugharị nke polycarbonate na-ejikwa nke nta nke nta na-enweta nlebara anya, na site na usoro mmeghari ohuru, ihe polycarbonate na-ekpofu ihe nwere ike gbanwee ka ọ bụrụ ngwaahịa ọhụrụ iji belata ihe mkpofu akụ.
