Isidingo se-PVC yomhlaba wonke nezintengo zombili ziyehla.
Kusukela ngo-2021, isidingo somhlaba wonke se-polyvinyl chloride (PVC) sibone ukukhuphuka okubukhali okungakaze kubonwe kusukela ngenhlekelele yezimali yomhlaba yango-2008. Kodwa maphakathi no-2022, isidingo se-PVC siphola ngokushesha futhi izintengo ziyehla ngenxa yokukhuphuka kwamazinga enzalo kanye nokwehla kwamandla emali okuphezulu kakhulu emashumini eminyaka. Ngo-2020, isidingo se-PVC resin, esetshenziselwa ukwenza amapayipi, amaphrofayili eminyango namafasitela, i-vinyl siding neminye imikhiqizo, sehle kakhulu ezinyangeni zokuqala zokuqubuka kwe-COVID-19 yomhlaba wonke njengoba umsebenzi wokwakha wehla. Idatha ye-S&P Global Commodity Insights ibonisa ukuthi emasontweni ayisithupha kuya ekupheleni kuka-April 2020, intengo ye-PVC ethunyelwe isuka e-United States yehle ngo-39%, kuyilapho intengo ye-PVC e-Asia naseTurkey nayo yehle ngo-25% yaya ku-31%. Izintengo ze-PVC kanye nesidingo zikhuphuke ngokushesha maphakathi no-2020, ngomfutho oqinile wokukhula ngokusebenzisa... -
Isikhwama sokupakisha sangaphandle se-Shiseido sokuvikela ilanga singesokuqala ukusebenzisa ifilimu ye-PBS ebolayo.

Ukuqhathaniswa kwe-LLDPE ne-LDPE.
I-linear low density polyethylene, ngokwesakhiwo ehlukile kune-polyethylene evamile ephansi, ngoba awekho amagatsha amaketango amade. Ukulandelana kwe-LLDPE kuncike ezinqubweni ezihlukene zokukhiqiza nokucubungula ze-LLDPE ne-LDPE. I-LLDPE ivame ukwakhiwa yi-copolymerization ye-ethylene kanye ne-alpha olefin ephakeme njenge-butene, i-hexene noma i-octene ekushiseni okuphansi nokucindezela. I-polymer ye-LLDPE ekhiqizwa inqubo ye-copolymerization inokusabalalisa kwesisindo samangqamuzana emincane kune-LDPE evamile, futhi ngesikhathi esifanayo inokwakheka komugqa okwenza ibe nezakhiwo ezahlukene ze-rheological. Izimpawu zokuncibilika kokuncibilika kwe-LLDPE zishintshwa ukuze zihambisane nezidingo zenqubo entsha, ikakhulukazi inqubo ye-extrusion yefilimu, engakhiqiza i-LLD yekhwalithi ephezulu... -
I-Jinan Refinery ithuthukise ngempumelelo impahla ekhethekile ye-geotextile polypropylene.
Muva nje, iJinan Refining and Chemical Company ithuthukise ngempumelelo i-YU18D, into ekhethekile ye-geotextile polypropylene (PP), esetshenziswa njengendawo eluhlaza yomugqa wokuqala wokukhiqiza we-PP filament geotextile wamamitha ayi-6, ongangena esikhundleni semikhiqizo efanayo evela kwamanye amazwe. . Kuyaqondakala ukuthi i-ultra-wide PP filament geotextile imelana ne-asidi ne-alkali corrosion, futhi inamandla aphezulu okudabula namandla okubamba.
