amakuru

PVC ni polymer ikorwa na polymerisiyumu yubusa ya vinyl chloride monomers (VCM) hamwe nabayitangije nka peroxide na azo compound cyangwa munsi yumucyo nubushyuhe.

PVC yahoze ari umusaruro mwinshi ku isi muri plastiki rusange, ni imwe muri plastiki eshanu rusange (PE polyethylene, PP polypropilene, PVC polyvinyl chloride, PS polystirene, ABS) .Birakoreshwa cyane.Mu bikoresho byubaka, ibicuruzwa byinganda, ibikenerwa bya buri munsi. , uruhu rwo hasi, tile hasi, uruhu rwubukorikori, umuyoboro, insinga na kabili, firime yo gupakira, amacupa, ibikoresho bya kopi, ibikoresho bifunga kashe, fibre nibindi bintu bikoreshwa cyane.

PVC yavumbuwe nko mu 1835 muri Amerika.PVC yakozwe mu nganda mu ntangiriro ya 1930. Kuva mu myaka ya za 1930, igihe kinini, umusaruro wa PVC wafashe umwanya wa mbere mu gukoresha plastike ku isi.

Ukurikije uburyo butandukanye bwo gusaba, PVC irashobora kugabanywamo: muri rusange PVC resin, urwego rwo hejuru rwa polymerisiyasi ya PVC resin, guhuza PVC resin. Ukurikije uburyo bwa polymerisation, PVC irashobora kugabanywamo ibyiciro bine byingenzi: guhagarika PVC, emulisiyo PVC, PVC nyinshi, igisubizo PVC.

Polyvinyl chloride ifite ibyiza byo gufata flame retardant (flame retardant agaciro karenga 40), kurwanya imiti myinshi (kurwanya aside hydrochloric yibanze, 90% acide sulfurike, 60% acide nitric na 20% hydroxide ya sodium), imbaraga zumukanishi hamwe no gukwirakwiza amashanyarazi .

Kuva mu mwaka wa 2016 kugeza 2020, umusaruro wa PVC ku isi wariyongereye. Dukurikije imibare ya Bloomberg, imibare ya PVC mu Bushinwa igera kuri 42% by'umusaruro ukomoka ku isi, hashingiwe ko umusaruro wa PVC ku isi ugera kuri toni miliyoni 54.31 muri 2020.

Mu myaka yashize, ikoreshwa ryinganda za PVC ryiyongereye cyane.Mu rwego rwo kongera umusaruro wa PVC mu gihugu hamwe n’ibicuruzwa bitumizwa mu mahanga bitiyongera ku buryo bugaragara, ubwiyongere bw’amakuru y’ibicuruzwa bigaragara ni ibisubizo bivuye mu kongera ibicuruzwa bikenewe nyuma yo kunoza umubano hagati y’ibitangwa n’ibisabwa. Muri 2018, ikigaragara cyo gukoresha Ethylene mu kirere cy’Ubushinwa yari toni miliyoni 889, yiyongereyeho toni miliyoni 1.18 cyangwa 6.66% ugereranije n’umwaka ushize. Muri rusange, ubushobozi bwacu bwo kubyaza umusaruro burenze kure ibyasabwaga, kandi igipimo cy’imikoreshereze y’ubushobozi ntabwo kiri hejuru.

Shin-etsu Uruganda rukora imiti

Shin-etsu yashinzwe mu 1926, ifite icyicaro i Tokiyo kandi ifite aho ikorera mu bihugu 14. Kwisi.

Shinetsu Chemical yateje imbere tekinoroji nini nini ya polymerisiyonike hamwe na NONSCALE itunganya umusaruro, iyobora inganda za PVC. Ubu, muri Amerika, Uburayi n'Ubuyapani amasoko atatu akomeye, nk'abakora inganda nini za PVC ku isi bafite ubushobozi bunini bwo gutanga umusaruro, gutanga ibicuruzwa bihamye -ibikoresho bingana kwisi.

Shin-yue Chemical izaba ifite PVC itanga umusaruro wa toni zigera kuri miliyoni 3.44 muri 2020.

2. Isosiyete ikora ibikomoka kuri peteroli

Isosiyete ikora peteroli ya Occidental ni isosiyete ikora ubushakashatsi kuri peteroli na gaze ikorera muri Houston ikorera muri Amerika, Uburasirazuba bwo hagati, na Amerika y'Epfo. Isosiyete ikora binyuze mu bice bitatu: Amavuta na gazi, imiti, Midstream na Marketing.

Inganda zikora imiti ahanini zitanga polyvinyl chloride (PVC), chlorine na hydroxide ya sodium (caustic soda) ya plastiki, imiti n’imiti itunganya amazi.

3.

Ineos Group Limited ni uruganda rwigenga rw’imiti rwigenga.Ineos ikora kandi ikagurisha ibicuruzwa byinshi bya peteroli, Ineos itanga ibicuruzwa byinshi byo gukuramo PVC no kubumba inshinge mu byiciro byinshi, kubaka porogaramu, amamodoka, ubuvuzi, ibikoresho byo gutunganya no gupakira. kwisi yose.

Inovyn ni vinyl chloride resin ihuriweho na Ineos na Solvay.Inovyn izibanda ku mutungo wa Solvay na Ineos hirya no hino mu nganda zose za vinyl chloride mu Burayi - polyvinyl chloride (PVC), soda ya caustic hamwe n’ibikomoka kuri chlorine.

4.Ubutaka bwa Chemistry

Westlake Corporation yashinzwe mu 1986 ikaba ifite icyicaro i Houston, muri Texas, ni uruganda mpuzamahanga kandi rutanga ibikomoka kuri peteroli n’ubwubatsi.

Westlake Chemical yaguze uruganda rukora PVC rwo mu Budage Vinnolit mu 2014 na Axiall ku ya 31 Kanama 2016. Isosiyete ikomatanyije yabaye iya gatatu mu gukora chlor-alkali nini na kabiri mu gukora uruganda rwa polyvinyl chloride (PVC) muri Amerika y'Amajyaruguru.
