Chachisanu, kufufuza: kupanikizika kwazinthu ndikwambiri
Pali lamulo lanyengo la PVC social inventory: kudzikundikira m'gawo loyamba → kutsika mu gawo lachiwiri → kuchotsedwa kosalekeza kwazinthu mu gawo lachitatu → kubwezeretsanso gawo lachinayi.Kuyambira Januwale mpaka Marichi munyengo yopumira, kudzikundikira kwa PVC nyengo mpaka pafupifupi zaka zam'mbuyomu.Komabe, kuyambira Marichi mpaka Meyi, liwiro la kusungirako limachedwa, makamaka chifukwa cha kufunikira kofooka kwapakhomo, kudalira kufunikira kwamphamvu kwakunja kuti asapite kosungirako.Kuyambira pakati mpaka kumapeto kwa Meyi, zofuna zakunja za PVC zidafowoka pang'ono, zofunikira zapakhomo zikadali zofooka, zomwe zidapangitsa kuti PVC idayamba kudziunjikira.
Malinga ndi mtengo wa malasha wa 800 yuan/tani, mtengo wa malasha wa 1250 yuan/tani, phindu la yuan 100/tani, mtengo wamagetsi sukwera yuan 0,25, mtengo wa calcium carbide wofanana ndi yuan 3000/tani, malinga ndi phindu lapakati. mlingo wa 400 yuan/ton, calcium carbide mtengo 3400 yuan/tani, katundu 400 yuan/tani, migodi yakunja kashiamu carbide mtengo 3800 yuan/ton, Mtengo wofanana wa PVC ku East China ndi 6800 yuan/tani, phindu limasinthasintha kuchokera -500 mpaka +1500, ndipo mtengo wa PVC umasinthasintha pakati pa 6300-8300.
Mapeto azinthu zopangira: calcium carbide mu mapeto azinthu zopangira ndizovuta kupereka chithandizo chamtengo wapatali mu theka loyamba la 2022. Mosiyana ndi 2021, chaka chino calcium carbide yochepa kusokonezeka kwamagetsi kwafooketsa, ndipo calcium carbide imatsimikiziridwa ndi zomangamanga zake zokha ndi zofuna za PVC.Kufuna kolimba kwa PVC sikukhazikika, kukokera pansi pa mphamvu yokoka ya calcium carbide pansi, zomwe zimadzetsa kutayika m'mabizinesi ena a calcium carbide, kuchulukirachulukira kwa zotumiza, kukhalapo kwa kutsika kwamitengo kuti kubweretse phindu lotumizira.Kukhudzidwa ndi kufinya phindu, kuchuluka kwa ntchito ya calcium carbide ya chaka chino poyerekeza ndi nthawi yomweyi chaka chatha chatsika, mbali yoperekera yachepetsedwa.
Mbali yothandizira: Mtengo wa PVC umayang'ana kwambiri phindu lake.Mu theka loyamba la chaka, phindu lamakampani opanga PVC ndilabwino nthawi zambiri.Choncho, ngakhale kuti chiwerengero cha nthawi yomweyi chaka chatha chatsika, chiwerengero cha ntchito za PVC chikadali pa mbiri yakale chaka chino.Kukonzekera kotsatira kumachepetsedwa, ndipo mapeto a PVC amatha kukhala opanikizika.
Kumapeto kwa Zofuna: PVC ndi ya zinthu zaposachedwa za malo ogulitsa nyumba, ndipo zomwe zimafunikira zimalumikizidwa ndi malo ogulitsa.Kuwoneka kowoneka kwa PVC kumakhala ndi kulumikizana kwakukulu ndikumaliza, kutsalira pang'ono kuyambika kwatsopano.Mu 2022, kuchepetsedwa kwa chiwongoladzanja chapakhomo kuphatikiza ndi njira zokhazikitsira kukula zidayambitsidwa, ndipo ziyembekezo zamphamvu zidachitika kangapo pakufunika.Ngakhale kuti kutumiza kunja kunakula mofulumira kuposa momwe ankayembekezera, zofuna zapakhomo sizinabwererenso kwambiri, ndipo zowona zofooka zidaposa ziyembekezo zamphamvu.Malo ogulitsa nyumba akuchira pang'onopang'ono mu theka lachiwiri la chaka, zofuna za PVC zikuyembekezeka kumasula malo ochepa, ndipo zofuna zakunja zikhoza kufooketsa, ponseponse, mbali yofunikira ikuyembekezeka kusintha koma yocheperako.
Mu theka lachiwiri la 2022, tikuyerekeza kuti kupezeka ndi kufunikira kwa PVC kumatha kuwonetsa kusintha pang'ono poyerekeza ndi theka loyamba la chaka, koma kusintha komwe kumabwera chifukwa cha kufunikira kuli kochepa, mphamvu yokoka ya PVC kapena kufooka, PVC ikuyembekezeka. kusinthasintha pakati pa 6300-8300, msika kapena kupitiriza hype kumbali yofunikira ya "zoyembekeza zamphamvu" ndi "zenizeni zofooka".
