Ukwenyuka kufinyelele ku-71.14%, futhi ikusasa le-PVC "laligcwele iziqhumane"

Njengoba lolu bhubhane lwalawulwa kulo nyaka futhi umnotho wezwe lami waqala ukusimama, ikusasa le-polyvinyl chloride (kamuva elibizwa ngokuthi i-PVC) laqala ukukhuphuka kusukela enanini eliphansi kakhulu ngo-April 1: 4955. Phakathi kwazo, inani eliphakeme kakhulu Ikusasa le-PVC eminyakeni emine edlule laliyi-8205. Ngokusho kwedatha yakamuva, intengo yokuvala yakamuva ye-PVC iphinde yavuka futhi yaphula irekhodi eliphezulu: 8480! Kusukela ngo-4955 ngo-April kuya ku-8480 ezinsukwini ezimbili zokuqala, ukwanda kwafinyelela ku-71.14%! Kungakhathaliseki ukuthi isuka enanini lokuhlinzekwa nesidingo, noma ukuthuthukiswa kwesakhiwo sezimboni kanye nomthelela wezici zesizini, ikusasa le-PVC lalo nyaka lingachazwa ngokuthi “umlilo ogcwele”!

Umhlaba mkhulu kakhulu, empeleni impilo ibalulekile
I-Polyvinyl Chloride (i-PVC) iyimpushana emhlophe engenabuthi futhi engenaphunga enokuqina kwamakhemikhali aphezulu kanye nepulasitiki enhle.
I-Polyvinyl chloride iyinto enkulu kunazo zonke ejwayelekile yokwenziwa kweresin ezweni lami futhi ingeyesibili ngobukhulu emhlabeni. Isetshenziselwa ikakhulukazi ukukhiqiza amaphrofayili, amaphrofayili, ukufakwa kwamapayipi, amapuleti, amashidi, ama-cable sheaths, amashubhu aqinile noma athambile, imishini yokumpontshelwa igazi kanye neFilimu njll.
izwe lami lingumkhiqizi omkhulu kanye nomthengi we-polyvinyl chloride. Intengo ye-polyvinyl chloride ithintwa yizici eziningi. Intengo ishintsha njalo futhi ububanzi bokuguquguquka bukhulu. Amabhizinisi okukhiqiza, ukuhweba kanye nokucubungula i-PVC abhekene nezingozi ezinkulu zebhizinisi futhi abambe iqhaza ezinhlobonhlobo zekusasa le-polyvinyl chloride. Isidingo sokugcinwa kwenani sinamandla uma kuqhathaniswa.
I-Polyvinyl chloride (PVC) ingumkhiqizo omkhulu kunawo wonke emhlabeni wamapulasitiki ahloselwe ukujwayelekile, futhi isetshenziswa kabanzi. Isetshenziswa kabanzi ezintweni zokwakha, imikhiqizo yezimboni, izidingo zansuku zonke, isikhumba saphansi, amathayela aphansi, isikhumba sokwenziwa, amapayipi, izintambo nezintambo, amafilimu okupakisha, amabhodlela, izinto ezinegwebu, izinto zokuvala uphawu, imicu, njll.
Ngo-2019, ukukhiqizwa kwe-polyvinyl chloride (PVC) kwaqhubeka nokukhula, futhi izinga lokukhula lafinyelela inani eliphakeme eminyakeni emihlanu edlule. Isilinganiso sokukhiqiza esiphelele se-PVC sigcina umkhuba okhuphukayo ozinzile. Ngokwezibalo ze-China Chlor-Alkali Industry Association,Ukukhiqizwa kwePVC yaseChinaifinyelele amathani ayizigidi eziyi-18.74 ngo-2019, okuwukukhula konyaka nonyaka ngama-7.31%.
Umthamo wokukhiqiza wePVC waseChina ugxile kakhulu esifundeni esisenyakatho

1. Ukusatshalaliswa kwesifunda kwamandla okukhiqiza we-PVC wezwe lami:
Mayelana nezifunda, umthamo wokukhiqiza we-PVC wezwe lami ugxile kakhulu esifundeni esisenyakatho. Indawo yaseShandong yenza u-13% womthamo wokukhiqiza we-PVC kazwelonke, indawo ye-Inner Mongolia nayo iphakeme njenge-10%, nezinye izifunda ezisenyakatho: i-Henan, i-Tianjin, ne-Xinjiang i-akhawunti 9%, 8%, kanye ne-7% ngokulandelanayo. Izifunda zaseMpumalanga China ezithuthuke ngokwezimboni ezifana neJiangsu neZhejiang zenza u-6% no-4% kuphela, okuhlanganisa kuphela u-10% womthamo kazwelonke wokukhiqiza we-PVC.

2. Ukukhishwa kwe-PVC yezwe lami eminyakeni yakamuva:
Eminyakeni yamuva, eChinaUkukhiqizwa kwe-PVCiye yanda unyaka nonyaka, futhi amandla ayo okuhlinzeka athuthukiswe kakhulu. Umkhuba usuwonke uya phezulu. Isizathu ngemuva kwayo asikwazi ukuhlukaniswa nokwanda okukhulu kokusetshenziswa kwe-PVC. Njengamanje, i-PVC yezwe lami inezimakethe ezimbili ezinkulu zabathengi: imikhiqizo eqinile nemikhiqizo ethambile. Imikhiqizo eqinile ikakhulukazi amaphrofayili ahlukahlukene, amapayipi, amapuleti, amashidi aqinile kanye nemikhiqizo ebunjiwe, njll.; imikhiqizo ethambile ikakhulukazi amafilimu, izintambo kanye nezintambo, isikhumba sokwenziwa, izindwangu zendwangu, amapayipi ahlukahlukene, amagilavu, amathoyizi, nembobo yaphansi ngezinjongo ezihlukahlukene. Izinto zokwakha, izicathulo zepulasitiki, nezinye izinto zokumboza ezikhethekile nama-sealants. Ngokombono wesakhiwo sokusetshenziswa kwe-PVC, ukusetshenziswa kwe- “ukufakwa kwamapayipi namapayipi” ibalwa ku-42%, okuyindawo esetshenziswa kakhulu ye-PVC; kulandelwa “amafilimu athambile namashidi”, okubalelwa ku-16%.
