izindaba

I-PVC iyi-polymer eyakhiwe yi-polymerization yamahhala ye-vinyl chloride monomers (VCM) enama-initiators afana ne-peroxide ne-azo compounds noma ngaphansi kwesenzo sokukhanya nokushisa.

I-PVC yayivame ukukhiqiza amapulasitiki avamile emhlabeni wonke, ingenye yepulasitiki evamile emihlanu (i-PE polyethylene, i-PP polypropylene, i-PVC polyvinyl chloride, i-PS polystyrene, i-ABS).Isetshenziswa kabanzi kakhulu.Ezinto zokwakha, imikhiqizo yezimboni, izidingo zansuku zonke , isikhumba esiphansi, i-tile yaphansi, isikhumba sokwenziwa, ipayipi, ucingo nekhebula, ifilimu yokupakisha, amabhodlela, izinto zegwebu, izinto zokuvala, imicu nezinye izici zisetshenziswa kabanzi.

I-PVC yatholwa ngo-1835 e-United States.I-PVC yenziwe ngezimboni ekuqaleni kwawo-1930. Kusukela ngawo-1930, isikhathi eside, ukukhiqizwa kwe-PVC kuye kwathatha indawo yokuqala ekusetshenzisweni kwepulasitiki emhlabeni.

Ngokusho kobubanzi besicelo esihlukile, i-PVC ingahlukaniswa ibe: i-resin ye-PVC evamile, i-polymerization degree ephezulu ye-PVC resin, i-PVC resin ehlanganisiwe.Ngokwezindlela ze-polymerization, i-PVC ingahlukaniswa ngezigaba ezine eziyinhloko: i-PVC yokumiswa, i-emulsion PVC, i-PVC yobuningi, Isixazululo se-PVC.

I-Polyvinyl chloride inobuhle be-flame retardant (inani elibuyisela amalangabi elingaphezu kuka-40), ukumelana namakhemikhali aphezulu (ukumelana ne-hydrochloric acid egxilile, 90% sulfuric acid, 60% nitric acid kanye no-20% sodium hydroxide), amandla amahle okusebenza kanye nokufakwa kukagesi. .

Kusukela ngo-2016 kuya ku-2020, ukukhiqizwa kwe-PVC emhlabeni wonke kwakukhuphuka. Ngokwezibalo ze-Bloomberg, ukukhiqizwa kwe-PVC yaseShayina kubala u-42% wokukhiqiza emhlabeni wonke, ngokusekelwe lapho ukukhiqizwa kwe-PVC yomhlaba wonke kulinganiselwa ukuthi kube amathani ayizigidi ezingu-54.31 ngo-2020.

Eminyakeni yamuva, ukusetshenziswa kwemboni ye-PVC kuye kwakhula kancane kancane.Ngaphansi kwesimo sokuthi umthamo wokukhiqiza we-PVC wasekhaya kanye nevolumu yokungenisa akukhuphuki kakhulu, ukukhula kwedatha yokusetshenziswa okusobala kuwumphumela wokukhulisa isidingo esiqinile ngemuva kokuthuthukiswa kobudlelwano phakathi kokuhlinzekwa nokufunwa.Ngo-2018, ukusetshenziswa okusobala kwe I-ethylene emkhathini waseShayina yayingamathani ayizigidi ezingu-889, ikhuphuka ngamathani ayizigidi ezingu-1.18 noma u-6.66% uma kuqhathaniswa nonyaka odlule. Kuwo wonke amandla ethu okukhiqiza adlula kude isidingo, futhi izinga lokusebenzisa amandla okukhiqiza aliphezulu.

Inkampani ye-Shin-etsu Chemical Company

Yasungulwa ngo-1926, iShin-etsu manje inekomkhulu e-Tokyo futhi inezindawo zokukhiqiza emazweni angu-14 emhlabeni jikelele.Iyibhizinisi elikhulu kunawo wonke emhlabeni lokukhiqiza i-wafer kanye nebhizinisi elikhulu kunawo wonke emhlabeni lokukhiqiza i-PVC.

I-Shinetsu Chemical isungule ubuchwepheshe bayo obukhulu be-polymerization kanye nenqubo yokukhiqiza ye-NONSCALE, ehola imboni ye-PVC.Manje, e-United States, eYurophu naseJapane izimakethe ezintathu ezinkulu, njengabakhiqizi abakhulu be-PVC emhlabeni abanomthamo omkhulu wokukhiqiza, ukunikezwa okuzinzile kokuphezulu. -ikhwalithi yezinto emhlabeni.

I-Shin-yue Chemical izoba namandla okukhiqiza e-PVC angaba amathani ayizigidi ezi-3.44 ngo-2020.

2. I-Occidental Petroleum Corporation

I-Occidental Petroleum Corporation iyinkampani yokuhlola nokukhiqiza uwoyela negesi ese-Houston esebenza e-United States, Middle East, naseNingizimu Melika.Le nkampani isebenza ngezigaba ezintathu: Amafutha Negesi, Amakhemikhali, AseMidstream Nezokumaketha.

Imboni yamakhemikhali ikhiqiza ikakhulukazi izinsalela ze-polyvinyl chloride (PVC), i-chlorine ne-sodium hydroxide (i-caustic soda) yamapulasitiki, imithi kanye namakhemikhali okwelapha amanzi.

I-Ineos Group Limited yinkampani ezimele yamazwe ngamazwe yamakhemikhali.I-Ineos ikhiqiza futhi ithengise inhlobonhlobo yemikhiqizo ye-petrochemical, i-Ineos inikeza inhlobonhlobo yemikhiqizo ye-PVC extrusion kanye nokubunjwa komjovo ngamabanga amaningi, ukwakhiwa kwezicelo, ezezimoto, ezokwelashwa, eziphathwayo nezimboni zokupakisha. emhlabeni wonke.

I-Inovyn iyibhizinisi elihlanganyelwe le-vinyl chloride resin phakathi kwe-Ineos ne-Solvay.I-Inovyn izogxilisa impahla ye-Solvay ne-Ineos kulo lonke uchungechunge lwemboni ye-vinyl chloride eYurophu - i-polyvinyl chloride (PVC), i-caustic soda nokuphuma kwe-chlorine.
