I-polycarbonate(I-PC) inamaqela e-carbonate kwi-molecular thein. Ngokwamaqela ahlukeneyo akwahlukeneyo kwisakhiwo se-molekyuli, inokwahlulwa ibe yi-Aliiphatic, iAlicyClic kunye ne-Aromatic. Phakathi kwabo, iqela elivuzayo linexabiso elisebenzayo. Eyona nto ibaluleke kakhulu yi-bisphenol i-polycarbonate, kunye nobunzima obuqhelekileyo bemoyarund (MW) ka-200000 ukuya kwi-100000.

I-Polycarbonate inezixhobo ezilungileyo ezigqibeleleyo, ezifana namandla, ukuqina, ukungavisisani kobushushu kunye nokungavisisani kobushushu kunye nokulungiswa ngokulula kunye nokulungiswa ngokulula kunye nokulungiswa ngokulula kunye nokulungiswa ngokulula kunye nokulungiswa ngokulula kunye nokulungiswa ngokulula kunye nokulungiswa ngokulula kunye nokulungiswa ngokulula kunye nokulungiswa ngokulula kunye nokulungiswa ngokulula. Eyona ndawo iphambili yokufumana izixhobo ze-elektroniki zizixhobo ze-elektroniki, isinyithi sephepha kunye neemoto. La magama mathathu ama-ofisi emalunga ne-80% ye-polycarbonate yokusebenzisa. Amanye amasimi asetyenziswa ngokubanzi kumatshini womatshini wemizi-mveliso, i-CD, ukupakisha, izixhobo zeOfisi, ifilimu, ukonwaba kunye nezixhobo zokukhusela, kwaye zibe zelinye icala le-ogeric elikhulayo.
Ngokuqhubela phambili kwetekhnoloji yendawo yokuhlala, indawo yokuhlala ye-China ye-China iphuhlise ngokukhawuleza kwiminyaka yakutshanje. Ekupheleni kuka-2022, inqanaba leShishini lePC lase China lidlule kwi-2,5 yezigidi zeetoni, kwaye iziphumo zimalunga ne-1.4 yezigidi zeetoni. Okwangoku, amashishini amakhulu amakhulu amakhulu aqokelela iKesichuang (i-600000 yeetoni / unyaka), i-Zhejiang Potrochemical (i-520000 i-Tons (i-500000 yeetoni) kunye neThongsha Tianjin (i-260000 yeetoni / unyaka).
Inzuzo yeenkqubo ezintathu zePC
Zintathu iinkqubo zemveliso zePC: Inkqubo yePOSGOPEN, inkqubo yetrapsares Kukho umahluko ocacileyo kwizinto ezingafunekiyo kunye neendleko kwinkqubo yemveliso. Iinkqubo ezintathu ezahlukeneyo zizisa amanqanaba enzuzo eyahlukeneyo kwi-PC.
Kule minyaka mihlanu idlulileyo, inzuzo ye-China ye-China ifikelele kwinqanaba eliphezulu ngo-2018, ukufikelela malunga ne-6500 yuan / ton. Emva koko, inqanaba lenzuzo liye lanqulwa unyaka ngonyaka. Ngexesha le-2020 ne-2021, ngenxa yokuncitshiswa kwenqanaba lokusebenzisa elibangelwe ngubhubhani, imeko yenzuzo ityhafile, kwaye indlela yePisgene yeFosgene ibonise ilahleko enkulu.
Ekupheleni kuka-2022, inzuzo yendlela yeTransessistition kwimveliso yePC yaseTshayina yeyona ndlela iphezulu, ifikelela kwi-159 yuan, ilandelwa yinzuzo ye-Polycondince Pholycoentement Pholycoents yendlela yePOSGEN yi-292 yuan / ton. Kule minyaka mihlanu idlulileyo, indlela yeTransessirisorrication ibisoloko yeyona ndlela ingenelo kwimveliso yenkqubo ye-CHC ye-CHC, ngelixa indlela engeyiyo i-phosgene inenzuzo ebuthathaka.
Uhlalutyo lwezinto ezichaphazela iNzuzo ye-PC
Okokuqala, amaxabiso aqhagamshelo lwe-bisphenol engafunekiyo A ne-DMC enefuthe ngqo kwi-PC, ngakumbi i-bitphenol a, enesisindo se-bisphenol a, esinengxaki yempembelelo kwi-PC.
Okwesibini, ukuguquguquka kwimarike yomthengi, ngakumbi ukuguquguquka kwe-macroeconomic, yiba nefuthe ngqo kwimarike yabathengi yePC. Umzekelo, ngexesha lama-2020 nowe-2021, xa ubhubhane ichaphazela, ukusela kwimarike yomthengi kwi-PCS kunciphile, kukhokelela ekunciphiseni amaxabiso e-PC kunye nefuthe ngqo kwintengiso ye-PC.
Ngo-2022, impembelelo yobuqhetseba iya kuba nzulu. Ixabiso leoli ebomvu iya kuqhubeka nokwehla, kwaye imakethi yabathengi iya kuba lihlwempu. Uninzi lweekhemikhali ze-China azifikeleli kwi-thegins eqhelekileyo yenzuzo. Njengoko ixabiso le-bisphenol a lihlala liphantsi, iindleko zemveliso zePC ziphantsi. Ukongeza, i-Dowypream iphinde yafumana imeko ethile, ke amaxabiso eenkqubo ezahlukeneyo zemveliso Iindidi zePC zigcine inzuzo eqinileyo, kwaye inzuzo iyaphucuka ngokuthe ngcembe. Yimveliso enqabileyo enemizi-mveliso ephezulu kwishishini lekhemikhali lase China. Kwixa elizayo, i-bisphenol intengiso iya kuqhubeka ivila, kwaye umthendeleko wentwasahlobo uyasondela. Ukuba ulawulo lobhubhane lukhutshwe ngendlela elungelelanisiweyo, ibango labathengi linokukhula kwi-wave, kwaye i-PC yenzuzo inokuqhubeka nokukhula.
