Chii chinonzi Polycarbonate?
Polycarbonate (PC) chinhu chepolymer chinoshandiswa zvakanyanya muindasitiri yemakemikari uye chimwe chezvinhu zvinofarirwa mumaindasitiri mazhinji nekuda kwekusiyana kwayo kwemuviri nemakemikari zvimiro. Muchikamu chino, tichaongorora zvakadzama kuumbwa uye zvivakwa zvePolycarbonate uye huwandu hwayo hwekushandisa.
1. Chimiro chemakemikari uye chimiro che polycarbonate
Polycarbonate ikirasi yebisphenol A (BPA) uye carbonate mapoka kuburikidza nepolycondensation reaction inogadzirwa neiyo linear polymer. Yayo molecular cheni ine huwandu hukuru hwemapoka ecarbonate (-O-CO-O-), chimiro ichi chinopa iyo polycarbonate zvinhu zvakanakisa kupisa kupisa, kujeka uye kukanganisa kuramba. Kugadzikana kwemakemikari epolycarbonate kunoita kuti ichengetedze zvimiro zvayo zvisingashanduki munzvimbo dzakanyanyisa, zvichiita kuti ive chinhu chakasimba kwazvo.
2. Zvinhu zvakakosha zve polycarbonate
Polycarbonate zvinhu zvinozivikanwa nehukuru hwayo hwemuviri zvimiro. Iyo ine yakanyanya kukwirisa mhedzisiro yekupikisa, 250 nguva iyo yegirazi yakajairwa, inoita kuti polycarbonate izivikanwe mumashandisirwo ayo anoda simba rakawanda uye kukanganisa kupikisa. Polycarbonate ine yakanakisa kupisa kupisa, inoramba yakagadzikana kubva -40 ° C kusvika 120 ° C, iyo inobvumira kuti iite zvakanaka munzvimbo dzepamusoro-tembiricha. Polycarbonate zvakare ine yakanaka optical transparency, ichiendesa zvinopfuura makumi mapfumbamwe muzana echiedza chinooneka, saka inowanzoshandiswa mukugadzira lenzi dzemaziso uye mavhavha akajeka.
3. Nzvimbo dzekushandisa dze polycarbonate
Nekuda kweiyo yakasarudzika midziyo yepolycarbonate zvinhu, inoshandiswa zvakanyanya mumaindasitiri akasiyana siyana. Muindasitiri yekuvaka, polycarbonate inowanzoshandiswa kugadzira mapaneru akareruka, zvekufurira zvinhu uye acoustic mapaneru. Yakanakisa kukanganisa kupikisa uye kujeka kunoita kuti ive yakakosha munzvimbo idzi. Muchikamu chemagetsi nemagetsi, polycarbonate inoshandiswa kugadzira zvinhu zvemagetsi, dzimba dzemidziyo yemumba uye makesi ebhatiri nekuda kwekudzivirira kwayo kupisa uye magetsi ekudzivirira. Polycarbonate inoshandiswawo zvakanyanya muindasitiri yemotokari, kunyanya yemarambi, mapaneru emidziyo nemahwindo. Zvinotonyanya kukosha, polycarbonate inoshandiswawo zvakanyanya mumunda wezvigadzirwa zvekurapa, zvakaita sejekiseni, midziyo yedialysis uye zviridzwa zvekuvhiya, nezvimwewo. Zvikumbiro izvi nekuda kwekusava nehuturu uye biocompatibility yezvinhu zvepolycarbonate.
4. Kushamwaridzana Nezvakatipoteredza uye Recycled Polycarbonate
Kunyangwe zvazvo polycarbonate iri chinhu chakasimba uye chinogoneka, iyo bisphenol A (BPA) inosanganisirwa mukugadzirwa kwayo yakakonzera gakava renharaunda. Sezvo tekinoroji iri kufambira mberi, zvigadzirwa zvepolycarbonate zvakawandisa zvakagadziridzwa izvo zvinoderedza kukanganisa kwezvakatipoteredza. Kudzokorodza kwepolycarbonate kuri kuwedzerawo kutariswa zvishoma nezvishoma, uye kuburikidza nekuita patsva, tsvina yepolycarbonate zvinhu zvinogona kushandurwa kuita zvigadzirwa zvitsva kuti zviwedzere kudzikisa tsvina yezviwanikwa.
Mhedziso
Chii chinonzi polycarbonate? Icho chinhu chepolymer chine hunhu hwakasiyana hwepamusoro, uye chinoshandiswa zvakanyanya mukuvaka, zvemagetsi nemagetsi midziyo yemagetsi, mota, zvekurapa uye mamwe minda nekuda kwekukanganisa kwayo kuramba, kupisa kupisa, kujeka uye kugadzikana kwemakemikari. Nekuwedzera kwekuziva kwekuchengetedzwa kwezvakatipoteredza, kudzokororwa kwepolycarbonate kuri kusimudzirwa zvishoma nezvishoma. Polycarbonate chinhu chinoshanda uye chine mukana wekusimudzira budiriro.
