Polycarbonate (PC) ndeyemanyorerwe carbonate boka, maererano nemapoka akasarudzika ane hunyanzvi hweboka rehunyoro, uye bisphelol inonyanya kukosha yerudzi rwehupfumi

Mufananidzo PC Yakatarwa Fomula

Polycarbonate ine simba rakanaka, kuoma, kupenga, kupisa kwemashandisirwo ezvekushandisa kwemagetsi, CD-ROM Zvishandiso uye mamwe minda yakawanda yakawanawo huwandu hwakawanda hwekushandisa, kuve mumwe weshanu mainjiniya mapurasitiki muboka rinokurumidza kukura.

Muna 2020, iyo Global PC Kugadzirwa Kwemamiriyoni Anenge Mamiriyoni emakumi mashanu emamiriyoni emakumi mairi nemakumi mapfumbamwe nemashanu emakumi mapfumbamwe nemakumi mairi, paine mando makumi maviri neshanu Iyo hombe yemusika yemusika inokwezva mafambiro akawanda kuti uwedzere kugadzirwa, zvinofungidzirwa kuti kune akawanda mapato ekuvakwa uye gore rimwe chete mumakore matatu anotevera, uye indasitiri yePC inoratidza yakawedzera kuendeswa kuChina.

Saka, ndedzipi nzira yekugadzira yePC? Ndeipi nhoroondo yekuvandudza yePC kumba uye kune imwe nyika? Ndeapi makuru ePC magadziri kuChina? Tevere, isu muchidimbu muchidimbu muzinga.

PC matatu mainstream kugadzirwa maitiro maitiro

InterFacial Polycondesation Photogas nzira, yechinyakare nzira yekuchinjisa nzira uye isiri-photogas moltin Ester exter nzira ndiyo matatu makuru ekugadzira maitiro muindasitiri yePC.
Mufananidzo
1. Interfcial Polycondeensation PHOSGEGE Nzira

Iyo ndiyo maitiro eiyo phosgee ive inert solium uye yemvura sodium hydroxide solution yeBisphenol a kuti iburitse mamexcular uremu, uye wobva waburitsa muhombodo yepamusoro. Pane imwe nguva, anenge 90% yezvigadzirwa zveindasitiri zvePolycarbonate zvaive zvakarongedzwa nenzira iyi.

Zvakanakira zvepanyama polycondeons Iko kushushikana ndeyekuti iyo polymerization maitiro inoda kushandiswa kweiyo yakanyanya muchetura phoragene uye ine chepfu uye ine methleiclene chloride, inokonzeresa kusvibiswa kwakakomba kwezvakatipoteredza.

Nyungudika Ester exchange nzira, zvakare inozivikanwa seTourgenic Polymerization, ichishandiswa kuumbwa kabhoni, dpc), pakushisa kwakadzika, kuChidimbu.

Zvinoenderana nezvinhu zvakagadzirwa zveDPC, zvinogona kukamurwa kuita tsika yekucheka nzira yekutsinhana (zvakare inozivikanwa seyunitict photogas nzira) uye isiri-Photogas yakaumbwa nzira yekuchinjana.

2. Chinyakare molten ester exchange nzira

Iyo yakakamurwa kuita zvikamu zviviri: (1) phosgene + phenol → Dpc; (2) DPC + BPA → PC, inova isina nzira phosgege maitiro.

Maitiro acho ipfupi, solvent-yemahara, uye iyo yekugadzira mari yakaderera pane yekukwenenzvera,

3. NON-PHOSSEGE MOLTEN ELER Exchange Nzira

Iyi nzira yakakamurwa kuita zvikamu zviviri: (1) DMC + pHOOL → DPC; (2.

Iyo-yechigadzirwa phenol yakawanikwa kubva kuEster Exchange uye kubvunzurudzwa inogona kudzoreredzwa kune synthesis yeDPC maitiro, saka ichiziva kushandisa zvekare uye hupfumi hwakanaka; Nekuda kwekuchena kwakanyanya kwezvinhu zvisina kugadzirwa, chigadzirwa chinodawo kuomeswa uye kushambidzwa, uye hunhu hwechigadzirwa hwakanaka. Maitiro acho haashandise phosgee, kune zvakatipoteredza hushamwari, uye iri nzira yakasvibira nzira.

Nezvimwe zvinodiwa zvemabhizimusi emabhizimusi emabhizimusi emabhizimusi ezvekuchengetedza pane zvekuchengetedza zvechikoro zvechirongwa
