Polycarbonate(PC) irimo amatsinda ya karubone mumurongo wa molekile. Dukurikije amatsinda atandukanye mumatsinda atandukanye mumiterere ya molekeular, irashobora kugabanywamo amatsinda ya aliphatic, alicyclic na aromatic. Muri bo, umutwe uhumura ufite agaciro gakomeye. Icy'ingenzi ni gisphenol polycarbonate, hamwe nuburemere rusange busanzwe uburemere bwa molecular (MW) ya 200000 kugeza 100000.

Polycarbonate ifite ibintu byiza byuzuye, nkimbaraga, gukomera, gukorera mu mucyo, kurwanya ubushyuhe no kurwanya ubukonje, gutunganya byoroshye no kudakemura byoroshye na flame deddaring. Ibipimo nyamukuru byo gusaba imirima nibikoresho bya elegitoroniki, urupapuro rwicyuma nimodoka. Konti eshatu zinganda zigera kuri 80% yo kunywa polycarbote. Izindi nzego zikoreshwa cyane mubice byinganda, CD, gupakira, ibikoresho byo mu biro, filime, ibikoresho byo kwivuza, kandi biba bimwe mubikoresho byihuta byihuta bya plastiki.
Hamwe no gutera imbere mu ikoranabuhanga rishinzwe kuzamura, guhagarika inganda za PC Ubushinwa byateye imbere vuba mu myaka yashize. Mu mpera za 2022, urugero rw'inganda za PC rw'Ubushinwa zarenze toni miliyoni 2.5, kandi ibisohoka ni toni miliyoni 1.4. Kugeza ubu, imishinga nini y'Abashinwa arimo Kesichuang (toni 600000 / umwaka), toni 520000.
Inyungu ya PC itatu
Hariho inzira eshatu zikora kuri PC: Gahunda idahwitse ya PC: Gahunda yo kwa Fosgene hamwe na PolyPacial Polycondingtion Gahunda ya Phosgene. Hariho itandukaniro rigaragara mubikoresho n'ibiciro bya fatizo nibiciro mubikorwa. Inzira eshatu zitandukanye zizana urwego rwinyungu zitandukanye kuri PC.
Mu myaka itanu ishize, inyungu ya PC y'Ubushinwa yageze ku rwego rwo hejuru muri 2018, igera kuri 6500 yuan / toni. Nyuma, urwego rwinyungu rwagabanutse umwaka numwaka. Muri 2020 na 2021, kubera kugabanya urwego rwo gukoresha ibizwe nicyorezo, ibintu byinyungu birinda cyane, hamwe nuburyo bwa soffane uburyo bwa fosgene nuburyo bworoshye bwerekanaga igihombo gikomeye.
Mu mpera za 2022, inyungu zuburyo bwa The Wastrogessional Mumusaruro wa PC Ubushinwa ni Urwego Rukuru, rugera kuri 2092 Yuan / toni, mugihe cyumusaruro wunguka ni 292 yuan / toni. Mu myaka itanu ishize, uburyo bwo kwamburwa bwamye bwarabaye uburyo bwumusaruro bwumusaruro wa PC yubushinwa, mugihe uburyo budahwitse bufite inyungu zidakomeye.
Isesengura ryibintu bigira ingaruka ku nyungu za PC
Ubwa mbere, ihindagurika ryibiciro bisphenol a na DMC ifite ingaruka zitaziguye kuri PC, cyane cyane ihindagurika rya gisphenol a, rifite uburemere bwingaruka zirenga 50% kubiciro bya PC.
Icya kabiri, ihindagurika mu isoko ry'umuguzi wa terminal, cyane cyane ihindagurika rya Macroeconomic, rigira ingaruka itaziguye ku isoko rya PC. Kurugero, mugihe cya 2020 na 2021, mugihe icyorezo kigiraho ingaruka, igipimo cyo gukoresha isoko ryabaguzi kuri PC cyagabanutseho, bikavamo kugabanuka cyane mubiciro bya PC hamwe ningaruka zitaziguye ku nyungu yisoko rya PC.
Muri 2022, ingaruka z'ikinya icyorezo zizaba zikomeye. Igiciro cyamavuta yubukorikori kizakomeza kugabanuka, kandi isoko ry'abaguzi rizaba rike. Imiti myinshi y'Ubushinwa ntabwo yageze ku nyungu zisanzwe. Mugihe igiciro cya Bisphenol akomeje kuba hasi, igiciro cya PC ni gito. Byongeye kandi, Downchs na we yagaruwe ku rugero runaka, bityo ibiciro by'imikorere itandukanye y'umusaruro bitandukanye, kandi inyungu iragenda itera imbere buhoro buhoro. Nibicuruzwa bidasanzwe bifite iterambere ryinshi mubikorwa bya shimi yubushinwa. Mu bihe biri imbere, Bisphenol isoko izakomeza kuba ubunebwe, kandi ibirori byimpeshyi byegereje. Niba kugenzura icyorezo byasohotse muburyo bwo gutumiza, icyifuzo cyabaguzi kirashobora gukura mumuraba, kandi umwanya wa PC ushobora gukomeza gukura.
