Polycarbonate(PC) iqukethe amaqembu e-carbonate ku-chain molecular. Ngokuya kwamaqembu ahlukene e-Ester esesakhiweni samangqamuzana, angahlukaniswa ngamaqembu angenangqondo, angesihle kakhulu namoya. Phakathi kwazo, iqembu le-aromatic linenani elisebenziseka kakhulu. Okubaluleke kakhulu yiBisphenol A polycarbonate, ngesisindo esijwayelekile esiyisisindo se-molecular aphakathi (MW) ka-200000 kuya ku-100000.

I-Polycarbonate inezindawo ezinhle ezinhle, njengamandla, ukuqina, ukucaca, ukumelana nokushisa kanye nokuphikiswa okubandayo kanye nokuphikiswa okubandayo, ukucubungula okulula kanye nokubuyiselwa kwamalangabi. Izinkambu zohlelo lokusebenza eziphambili ezansi ziyimishini ye-elekthronikhi, i-Sheet Metal Nezimoto. Lezi zimboni ezintathu zezezimboni ezingaba ngu-80% ukusetshenziswa kwePolycarbonate. Eminye imikhakha isetshenziswa kabanzi kwizingxenye zemishini yezimboni, i-CD, ukupakisha, imishini yehhovisi, ukunakekelwa kwezokwelapha, ifilimu, ukuzilibazisa nemishini yokuvikela, futhi sekuyinye yezigaba ezivikelayo ezikhulayo zepulasitiki ezinhlanu zobunjiniyela.
Ngokuthuthuka kobuchwepheshe bendawo, ukwenziwa kwendawo kwemboni ye-PC yeChina yathuthuka ngokushesha eminyakeni yamuva. Ekupheleni kuka-2022, isikali semboni ye-PC yaseChina sekwedlule amathani / unyaka wezigidi ezingama-2,5, futhi okuphumayo kungamathani ayizigidi eziyi-1,4. Njengamanje, amabhizinisi amakhulu aseChina afaka i-Kesichuang (600000 amathani / unyaka), amathani ama-zhejiang (amathani angama-520000 / unyaka), i-zhongsha tiannjin (260000 amathani / unyaka / unyaka / unyaka / ngonyaka
Inzuzo yezinqubo ezintathu ze-PC
Kunezinqubo ezintathu zokukhiqiza ze-PC: Inqubo ye-phosgene, inqubo yokuThatha kanye nenqubo yokuxhumana ye-polyconderation ye-Phosgene. Kunokwehluka okusobala kokusetshenziswa okungavuthiwe nezindleko kwinqubo yokukhiqiza. Izinqubo ezintathu ezihlukene ziletha amazinga ahlukile wenzuzo ye-PC.
Eminyakeni emihlanu edlule, inzuzo ye-CH China yafinyelela ezingeni eliphakeme kakhulu ngonyaka we-2018, ifinyelela cishe ngo-6500 yuan / ton. Kamuva, izinga lenzuzo lehlile unyaka nonyaka. Ngo-2020 no-2021, ngenxa yokwehliswa kwezinga lokusebenzisa okubangelwa ubhubhane, isimo senzuzo sincipha kakhulu, kanye nendlela ye-conderface clethetion phosgene nendlela ye-phosgene ikhombise ukulahleka okukhulu.
Ekupheleni kuka-2022, inzuzo yendlela yokufaka i-Transterificatificatimion eChina's PC ukukhiqizwa okuphezulu kakhulu, okufinyelela i-2092 yuan / ithoni, kulandelwe inzuzo ye-1592 yuan / ithoni, ngenkathi ukukhiqizwa kwe-theoretical kwenzuzo yendlela ye-phosgene ingu-292 yuan / ithoni. Eminyakeni emihlanu eyedlule, indlela yokuTkisa ibilokhu iyindlela yokukhiqiza inzuzo kakhulu enqubweni yokukhiqiza i-PC yaseChina, kuyilapho indlela ye-phosgene inenzuzo ebuthakathaka kakhulu.
Ukuhlaziywa kwezinto ezithinta inzuzo ye-PC
Okokuqala, ukuguquguquka kwentengo ye-Raw Izinto ze-Bisphenol A ne-DMC kunomthelela oqondile kwizindleko ze-PC, ikakhulukazi ukuguquguquka kwentengo kwe-Bisphenol A, okunesisindo somthelela ongaphezu kwama-50% kwizindleko ze-PC.
Okwesibili, ukuguquguquka kwemakethe yabathengi ebulalayo, ikakhulukazi ukuguquguquka kwe-Macroeconomic, kube nomthelela oqondile emakethe yabathengi be-PC. Isibonelo, ngesikhathi sika-2020 no-2021, lapho ubhubhane luthinta, isilinganiso sokusetshenziswa kwemakethe yabathengi ku-PC sekwehlile, kuholele ekunciphiseni okuphezulu kwamanani entengo ye-PC kanye nenzuzo eqondile kwinzuzo yemakethe ye-PC.
Ngo-2022, umthelela wobhubhane uzoba sina. Intengo kawoyela ongahluziwe izoqhubeka yehla, futhi imakethe yabathengi izoba mpofu. Amakhemikhali amaningi aseChina awafinyelelanga ama-margins ajwayelekile wenzuzo. Njengoba intengo yeBisphenol ahlala ephansi, izindleko zokukhiqiza ze-PC ziphansi. Ngaphezu kwalokho, i-DownTream ibuye yatholakele ngezinga elithile, ngakho-ke amanani entengo yezinhlobo ezahlukahlukene zenqubo yokukhiqiza ye-PC zigcine inzuzo eqinile, futhi inzuzo iyathuthuka kancane kancane. Kungumkhiqizo ongavamile ngokuchuma okuphezulu embonini yamakhemikhali yaseChina. Ngokuzayo, i-busphenol imakethe izoqhubeka nokuvilapha, futhi umcimbi wentwasahlobo usondela. Uma ukulawulwa kwe-ebhubhane kukhishwa ngendlela ehlelekile, ukufunwa kwabathengi kungakhula ngegagasi, futhi isikhala senzuzo ye-PC singaqhubeka nokukhula.
