Intangiriro kubyerekeranye n'ubushobozi bwa PVC mubushinwa no kwisi yose
Dukurikije imibare yo mu 2020, ubushobozi bwa PVC ku isi hose bwageze kuri toni miliyoni 62 naho umusaruro wose wageze kuri toni miliyoni 54. Kugabanuka kwumusaruro byose bivuze ko ubushobozi bwo gukora butigeze bukora 100%. Kubera ibiza, politiki zaho nibindi bintu, umusaruro ugomba kuba munsi yubushobozi bwumusaruro. Bitewe n’igiciro kinini cy’ibicuruzwa bya PVC mu Burayi no mu Buyapani, ubushobozi bwa PVC ku isi bwibanda cyane cyane muri Aziya y’Amajyaruguru y’Amajyaruguru, aho Ubushinwa bufite hafi kimwe cya kabiri cy’ubushobozi bwa PVC ku isi. Nk’uko imibare y’umuyaga ibigaragaza, mu 2020, Ubushinwa, Amerika n’Ubuyapani n’ahantu h’ingenzi hakorerwa PVC ku isi, aho ubushobozi bw’umusaruro bugera kuri 42%, 12% na 4%. Muri 2020, ibigo bitatu byambere muri PVC kwisi yose ... -
Ibihe bizaza bya PVC Resin
PVC ni ubwoko bwa plastiki bukoreshwa cyane mubikoresho byo kubaka. Kubwibyo, ntabwo izasimburwa igihe kirekire mugihe kizaza, kandi izaba ifite amahirwe menshi yo gukoreshwa mubice bitaratera imbere mugihe kizaza. Nkuko twese tubizi, hari inzira ebyiri zo kubyara PVC, bumwe nuburyo mpuzamahanga busanzwe bwa Ethylene, ubundi nuburyo bwa calcium karbide idasanzwe mubushinwa. Inkomoko yuburyo bwa Ethylene ahanini ni peteroli, mugihe inkomoko yuburyo bwa calcium karbide ari amakara, hekeste nu munyu. Aya masoko yibanze cyane mubushinwa. Kuva kera, Ubushinwa PVC bwuburyo bwa calcium karbide bwabaye kumwanya wambere. Cyane cyane kuva 2008 kugeza 2014, Ubushinwa PVC bwo gukora umusaruro wa calcium karbide uburyo bwiyongera, ariko kandi bwazanye ... -
PVC Resin ni iki?
Polyvinyl chloride (PVC) ni polymer polymerized na vinyl chloride monomer (VCM) muri peroxide, azo compound hamwe nabandi batangije cyangwa ukurikije uburyo bwa polymerisiyonike yubusa hakoreshejwe urumuri nubushyuhe. Vinyl chloride homopolymer na vinyl chloride copolymer hamwe hamwe bita vinyl chloride resin. PVC yahoze ari plastiki nini ku isi muri rusange, ikoreshwa cyane. Ikoreshwa cyane mubikoresho byubaka, ibicuruzwa byinganda, ibikenerwa bya buri munsi, uruhu rwo hasi, amabati hasi, uruhu rwubukorikori, imiyoboro, insinga ninsinga, firime ipakira, amacupa, ibikoresho bifuro, ibikoresho bifunga kashe, fibre nibindi. Ukurikije uburyo butandukanye bwo gusaba, PVC irashobora kugabanywamo: rusange-intego ya PVC resin, urwego rwo hejuru rwa polymerisation PVC resin na ... -
Idirishya ry'ubukemurampaka rya PVC rikomeje gufungura
Mu rwego rwo gutanga ibintu, kariside ya calcium, icyumweru gishize, igiciro rusange cyisoko rya calcium karbide yagabanutseho 50-100 yuan / toni. Umutwaro rusange wibikorwa bya calcium karbide yinganda byari bihagaze neza, kandi gutanga ibicuruzwa byari bihagije.
