Ingakanani inqubekelaphambili yomthamo omusha we-polypropylene waseChina ngo-2023?
Ngokusho kokuqapha, kusukela manje, umthamo wokukhiqiza we-polypropylene waseChina ungamathani ayizigidi ezingama-39.24. Njengoba kukhonjisiwe kulesi sibalo esingenhla, umthamo wokukhiqiza we-polypropylene waseShayina ubonise ukukhula okuqhubekayo unyaka nonyaka. Kusukela ngo-2014 kuya ku-2023, izinga lokukhula kwamandla okukhiqiza i-polypropylene yaseShayina lalingu-3.03% -24.27%, ngesilinganiso sokukhula sonyaka esingu-11.67%. Ngo-2014, amandla okukhiqiza akhuphuke ngamathani ayizigidi ezingu-3.25, ngezinga lokukhula kwamandla okukhiqiza angu-24.27%, okuyizinga eliphezulu lokukhula kwamandla okukhiqiza kule minyaka eyishumi edlule. Lesi sigaba sibonakala ngokukhula ngokushesha kwamalahle ezitshalweni ze-polypropylene. Izinga lokukhula ngo-2018 lalingu-3.03%, liphansi kakhulu kule minyaka eyishumi edlule, futhi umthamo wokukhiqiza owawusanda kufakwa wawuphansi kakhulu ngalowo nyaka. ... -
I-PVC:I-oscillation yebanga elincane, ukukhuphuka okuqhubekayo kusadinga idrayivu eya phansi komfula
Ukulungiswa okuncane ekuhwebeni kwansuku zonke ngomhla ka-15. Ngomhlaka-14, kwakhululwa izindaba zokuthi ibhange elikhulu lehlise imfuneko ye-reserve, futhi isimo sengqondo sokuhle emakethe savuka. Ikusasa lomkhakha wamandla ohweba ebusuku nawo rosesynchronously. Kodwa-ke, ngokombono oyisisekelo, ukubuyiswa kokuhlinzekwa kwemishini yokulungisa ngoSepthemba kanye nesimo esintengayo sokufuna ukwehla nomfula kusewukudonsa okukhulu emakethe njengamanje. Kufanele kuphawulwe ukuthi asiyona i-bearish ephawulekayo emakethe yesikhathi esizayo, kodwa ukwanda kwe-PVC kudinga ukuthi umfula ukhuphule kancane kancane umthwalo futhi uqale ukugcwalisa izinto zokusetshenziswa, ukuze ubambe ukunikezwa kwabafikayo abasha ngoSepthemba ngangokunokwenzeka futhi uqhube i-stag yesikhathi eside ... -
Izintengo ze-polypropylene ziyaqhubeka nokukhuphuka, okubonisa ukwanda okukhulu kokukhiqizwa komkhiqizo wepulasitiki
NgoJulayi 2023, ukukhiqizwa komkhiqizo wepulasitiki waseChina kwafinyelela kumathani ayizigidi eziyisi-6.51, okuwukunyuka ngo-1.4% unyaka nonyaka. Isidingo sasekhaya siya ngokuya sithuthuka, kodwa isimo sokuthekelisa kwemikhiqizo yepulasitiki sisesibi; Kusukela ngoJulayi, imakethe ye-polypropylene iye yaqhubeka ikhula, futhi ukukhiqizwa kwemikhiqizo yepulasitiki kuye kwakhula kancane kancane. Esigabeni sakamuva, ngokwesekwa kwezinqubomgomo ezinkulu zokuthuthukiswa kwezimboni ezihlobene ezansi nomfula, ukukhiqizwa kwemikhiqizo yepulasitiki kulindeleke ukuthi kuqhubeke ukwanda ngo-August. Ngaphezu kwalokho, izifundazwe eziyisishiyagalombili eziphezulu mayelana nokukhiqizwa komkhiqizo yiSifundazwe sase-Guangdong, iSifundazwe saseZhejiang, iSifundazwe saseJiangsu, iSifundazwe saseHubei, iSifundazwe saseShandong, iSifundazwe saseFujian, isifunda esizimelayo saseGuangxi Zhuang, kanye neSifundazwe sase-Anhui.

Uyibheka kanjani imakethe yesikhathi esizayo ngokukhuphuka okuqhubekayo kwezintengo ze-PVC?
Ngo-September 2023, eqhutshwa izinqubomgomo ezinhle zomnotho omkhulu, okulindelwe okuhle ngesikhathi “se-Nine Silver Ten”, kanye nokukhuphuka okuqhubekayo kwekusasa, intengo yemakethe ye-PVC yenyuke kakhulu. Kusukela ngomhla ka-5 Septhemba, intengo yemakethe yasekhaya ye-PVC iye yanyuka futhi, nenkomba evamile ye-calcium carbide 5-type material ilinganiselwa ku-6330-6620 yuan/ton, kanye nenkomba evamile yezinto ezisetshenziswayo ze-ethylene ingu-6570-6850 yuan/ton. Kuyaqondakala ukuthi njengoba amanani entengo e-PVC eqhubeka nokukhuphuka, ukuthengiselana ezimakethe kuyaphazamiseka, futhi izintengo zokuthumela zabadayisi zinesiphithiphithi uma kuqhathaniswa. Abanye abathengisi babone ukwehla ekuthengisweni kwabo kokuqala, futhi abanandaba kakhulu nokubuyisela amanani entengo ephezulu. Isidingo se-downstream kulindeleke ukuthi sikhule kancane kancane, kodwa okwamanje i-downstream p... -
Izintengo ze-polypropylene zika-Agasti zikhuphuke ngoSepthemba isizini zingafika njengoba kuhleliwe
Imakethe ye-polypropylene yehla phezulu ngo-Agasti. Ekuqaleni kwenyanga, inkambiso yekusasa le-polypropylene yayiguquguquka, futhi intengo yendawo yahlungwa ngaphakathi kwebanga. Ukuhlinzekwa kwemishini yokulungisa kusengaphambili kuqale kabusha ukusebenza ngokulandelana, kodwa ngesikhathi esifanayo, inani elincane lokulungiswa okuncane okusha liye lavela, futhi umthwalo wonke wedivayisi unyukile; Nakuba idivayisi entsha iqede ukuhlolwa ngempumelelo phakathi no-Okthoba, akukho okukhipha umkhiqizo ofanelekayo okwamanje, futhi ingcindezi yokuhlinzeka kusayithi imisiwe; Ngaphezu kwalokho, inkontileka eyinhloko ye-PP yashintsha inyanga, ukuze okulindelwe yimboni ngemakethe yesikhathi esizayo kwande, ukukhululwa kwezindaba zemakethe yemakethe, kwakhulisa ikusasa le-PP, kwakha ukusekelwa okuhle kwemakethe yendawo, kanye ne-petroc... -
Inzuzo yemboni yemikhiqizo yepulasitiki iyaqhubeka nokwenza ngcono amanani entengo ye-polyolefin aqhubekele phambili
Ngokusho kweNational Bureau of Statistics, ngoJuni 2023, amanani entengo abakhiqizi bezimboni kazwelonke ehle ngo-5.4% unyaka nonyaka kanye no-0.8% inyanga nenyanga. Izintengo zokuthenga zabakhiqizi bezimboni zehle ngo-6.5% unyaka nonyaka kanye no-1.1% inyanga nenyanga.

Kusengenzeka ukuthi kukhuphukele phezulu ekubumbeni okuqhubekayo kwesikhathi esifushane, okulinde isiqondiso esivela ku-n... -
Yiziphi Izinhlobo Ezihlukene Ze-polyethylene?
I-Polyethylene ivamise ukuhlukaniswa ibe enye yezinhlanganisela ezinkulu ezimbalwa, ezivame kakhulu ezihlanganisa i-LDPE, i-LLDPE, i-HDPE, ne-Ultrahigh Molecular Weight Polypropylene. Okunye okuhlukile kufaka i-Medium Density Polyethylene (MDPE), i-polyethylene ye-Ultra-low-molecular-weight (ULMWPE noma i-PE-WAX), i-High-molecular-weight polyethylene (HMWPE), i-High-density cross-linked cross-linked polyethylene (HDXLPE), i-polyethylene e-Cross-linked (PEX noma i-XLPE) I-Verlypethylene (i-XLPE) ne-XLPE I-Chlorinated polyethylene (CPE). I-Low-Density Polyethylene (LDPE) iyinto evumelana nezimo kakhulu enezici zokugeleza ezihlukile eziyenza ifaneleke ngokukhethekile izikhwama zokuthenga nezinye izinhlelo zokusebenza zefilimu yepulasitiki. I-LDPE ine-ductility ephezulu kodwa amandla aphansi aqinile, okubonakala emhlabeni wangempela ngokuthambekela kwayo ukwelula ...
