Polyakarubone(PC) irimo amatsinda ya karubone mumurongo wa molekile. Ukurikije amatsinda atandukanye ya ester muburyo bwa molekile, irashobora kugabanywamo amatsinda ya alifatique, alicyclic na aromatic. Muri byo, itsinda rya aromatic rifite agaciro gakomeye. Icy'ingenzi ni bispenol A polyakarubone, hamwe n'uburemere rusange buringaniye bwa molekile (MW) ya 200000 kugeza 100000.

Polyakarubone ifite ibintu byiza byuzuye, nkimbaraga, ubukana, gukorera mu mucyo, kurwanya ubushyuhe no kurwanya ubukonje, gutunganya byoroshye no kutagira umuriro. Ibyingenzi byingenzi byo kumurongo wibikoresho ni ibikoresho bya elegitoronike, urupapuro rwicyuma nimodoka. Izi nganda uko ari eshatu zingana na 80% byo gukoresha polyakarubone. Indi mirima nayo ikoreshwa cyane mubice byimashini zinganda, CD, gupakira, ibikoresho byo mubiro, ubuvuzi, firime, imyidagaduro nibikoresho birinda, kandi byabaye kimwe mubyiciro byihuta byiterambere bya plastiki eshanu zubuhanga.
Hamwe niterambere ryikoranabuhanga ryaho, aho inganda za PC zo mubushinwa zateye imbere byihuse mumyaka yashize. Mu mpera za 2022, igipimo cy’inganda za PC mu Bushinwa cyarengeje toni miliyoni 2.5 / ku mwaka, naho umusaruro ugera kuri toni miliyoni 1.4. Kugeza ubu, inganda nini mu Bushinwa zirimo Kesichuang (toni 600000 / umwaka), Zhejiang Petrochemical (toni 520000 / umwaka), Luxi Chemical (toni 300000 / mwaka) na Zhongsha Tianjin (toni 260000 / umwaka).
Inyungu yibikorwa bitatu bya PC
Hariho uburyo butatu bwo gukora kuri PC: inzira ya fosgene, inzira ya transesterifike hamwe na polycondensation ya foscene. Hariho itandukaniro rigaragara mubikoresho fatizo nibiciro mubikorwa byo gukora. Inzira eshatu zitandukanye zizana inyungu zinyuranye kuri PC.
Mu myaka itanu ishize, inyungu za PC y'Ubushinwa zageze ku rwego rwo hejuru muri 2018, zigera kuri toni 6500. Nyuma, urwego rwinyungu rwaragabanutse uko umwaka utashye. Muri 2020 na 2021, kubera igabanuka ry’urwego rw’imikoreshereze yatewe n’icyorezo, ibintu byungutse byagabanutse ku buryo bugaragara, kandi uburyo bwo guhuza imiyoboro ya fosgene n’uburyo butari fosgene bwerekanye igihombo gikomeye.
Mu mpera za 2022, inyungu zuburyo bwa transesterifike mu musaruro wa PC mu Bushinwa nizo zisumba izindi, zigera kuri 2092 yu ni 292 gusa. Mu myaka itanu ishize, uburyo bwa transesterifike burigihe nuburyo bwunguka cyane mubikorwa byo gutunganya PC mubushinwa, mugihe uburyo butari fosgene bufite inyungu nkeya.
Isesengura ryibintu bigira ingaruka ku nyungu za PC
Ubwa mbere, ihindagurika ryibiciro byibikoresho fatizo bisphenol A na DMC bigira ingaruka itaziguye kubiciro bya PC, cyane cyane ihindagurika ryibiciro bya bispenol A, ifite uburemere burenga 50% kubiciro bya PC.
Icya kabiri, ihindagurika ku isoko ry’abaguzi rya terefone, cyane cyane ihindagurika rya macroeconomic, rigira ingaruka zitaziguye ku isoko ry’abaguzi ba PC. Kurugero, mugihe cya 2020 na 2021, mugihe icyorezo cyibasiye, igipimo cy’imikoreshereze y’isoko ry’umuguzi kuri PC cyaragabanutse, bituma igabanuka rikabije ry’ibiciro bya PC ndetse n’ingaruka zitaziguye ku nyungu z’isoko rya PC.
Muri 2022, ingaruka z'icyorezo zizaba zikomeye. Igiciro cya peteroli ntikizakomeza kugabanuka, kandi isoko ryabaguzi rizaba ribi. Imiti myinshi yo mu Bushinwa ntabwo yageze ku nyungu zisanzwe. Nkuko igiciro cya bispenol A gikomeza kuba gito, igiciro cya PC ni gito. Byongeye kandi, epfo na ruguru nayo yagaruwe ku rugero runaka, bityo ibiciro byubwoko butandukanye bwo gutunganya umusaruro wa PC byagumanye inyungu zikomeye, kandi inyungu iragenda yiyongera buhoro buhoro. Nibicuruzwa bidasanzwe bifite iterambere ryinshi mu nganda z’imiti mu Bushinwa. Mu bihe biri imbere, bispenol A isoko izakomeza kuba umunebwe, kandi umunsi mukuru wimpeshyi uregereje. Niba kurwanya icyorezo kirekuwe muburyo bukurikiranye, ibyifuzo byabaguzi birashobora kwiyongera mumuraba, kandi umwanya winyungu PC urashobora gukomeza kwiyongera.
