Mafambiro ePVC, Mafambiro eCarbide PVC neEthylene PVC

PVC ipurasitiki inoshandiswa zvakanyanya mukuvaka. Saka, haizotsiviwa kwenguva yakareba mune ramangwana, uye ichava netariro huru yekushandiswa munzvimbo dzisina kusimba mune ramangwana.

Sezvatinoziva tese, kune nzira mbiri dzekugadzira PVC, imwe ndiyo nzira yepasi rose ye ethylene, uye imwe ndiyo nzira yakasiyana ye calcium carbide muChina. Nzira ye ethylene inonyanya kushandiswa petroleum, nepo nzira ye calcium carbide inonyanya kushandiswa marasha, limestone nemunyu. Zviwanikwa izvi zvinonyanya kushandiswa muChina. Kwenguva yakareba, nzira ye calcium carbide yePVC yeChina yave iri pamberi. Kunyanya kubva muna 2008 kusvika 2014, kugona kwePVC yekugadzira nzira ye calcium carbide muChina kwave kuchiwedzera, asi kwakaunzawo matambudziko mazhinji ekuchengetedza nharaunda.

Simba rinoshandiswa pakugadzira calcium carbide rakakura kwazvo, saka izvi zvichakonzera matambudziko pamagetsi eChina. Nekuti magetsi anogadzirwa nekupisa marasha, inoda kushandisa marasha akawanda, saka kupisa marasha kuchasvibisa mhepo. Zvisinei, China yakaita shanduko mumitemo kwemakore. China iri kugara ichivandudza cheni yayo yemaindasitiri. Iye zvino tinogona kuona kuti China yave kupinza mafuta akawanda, uye mabhizinesi emuno anokurudzirwa kupinza mafuta kuti achenese zvigadzirwa zviri pasi. Saka, mumakore achangopfuura, vagadziri vatsva ve ethylene process vakawedzerwa muChina, uye kugona kwese kwekugadzira PVC itsva muChina mumakore achangopfuura ndiko kugona kwekugadzira ethylene process. Kugona kwekugadzira kwenzira ye calcium carbide yeChina kwamisa kubvumidzwa kutsva. Saka, munguva pfupi iri kutevera, huwandu hwemiti ye ethylene muChina hucharamba huchiwedzera uye maitiro e calcium carbide acharamba achidzikira. Mune ramangwana, huwandu hwe ethylene process yeChina hucharamba huchiwedzera, uye zvishoma nezvishoma huchava mutengesi anotungamira we ethylene process PVC pasi rose.
