Cov roj Crude thiab naphtha tus nqi tau nce siab thaum muaj kev tsis sib haum xeeb nyob rau hauv Middle East cuam tshuam cov khoom lag luam tseem ceeb. Ua ke nrog kev saib xyuas zoo ntawm cov tuam txhab petrochemical hauv thawj peb lub hlis twg txwv tsis pub muaj peev xwm tsim tau, lub ntiaj teb tus nqi cua daj cua dub rau cov khoom siv tshuaj lom neeg muaj zog.
Cov nqi ntawm cov khoom xws li engineering plastics xws li PA66 thiab PA6, mus rau polyurethane, hluavtaws roj hmab, thiab ntau yam tshuaj lom neeg tau nce mus rau ntau- xyoo siab. Cov kev lag luam hauv qab suav nrog tsheb, textiles, electronics, thiab cov khoom vaj khoom tsev raug yuam kom dais tus nqi siab, raws li cov saw hlau thoob ntiaj teb kev lag luam nkag mus rau kev hloov kho tshiab ntawm tus nqi.
Thaum pib lub Plaub Hlis, Toray thiab Asahi Kasei raug rho tawm thawj zaug rau kev nce nqi ntawm cov khoom nylon, nrog ntau tshaj li kaum ob cov tshuaj loj xws li BASF, Celanese, thiab Invista tom qab nplua, thawb lub ntiaj teb nylon kev lag luam saw mus rau hauv kev sib sau ua ke tus nqi nce mus.
Asahi Kasei yuav nce nqi ntawm PA66 fibers rau airbags thiab log cords, nrog rau PA66 resins rau automotive rearview daim iav vaj tsev nyob los ntawm 170 yen ib kilogram pib lub Plaub Hlis 15, nrog rau kev hloov kho yuav tsum vov lub domestic thiab txawv teb chaws kev lag luam.
Toray tau siv thoob plaws -- pawg thawj coj tus nqi nce ntawm cov khoom siv tshuaj fiber ntau pib lub Plaub Hlis. PA66 filaments thiab staple fibers tau nce los ntawm ntau tshaj 20 yen ib kilogram, acrylic staple fibers los ntawm ntau tshaj 110 yen / kg, thaum PA6, polyester, thiab polypropylene tsis yog - woven fabrics kuj tau nce los ntawm 50 mus rau 110 yen ib kilogram.
Cov lag luam hauv tsev kuj raug txwv los ntawm cov khoom tsis txaus. Invista Nylon Chemicals (China) Co., Ltd. thiab Shenma Kev Lag Luam tau tshaj tawm cov ntawv ceeb toom quab yuam majeure rau lawv cov khoom. Tuam Tshoj Petrochemical Development Corporation (CPDC) tau tshaj tawm kev kaw ib ntus los txiav cov tub ntxhais tsim muaj peev xwm, ua rau muaj kev sib cog lus ntse hauv kev muab cov khoom tseem ceeb xws li adiponitrile, hexamethylenediamine, PA66 chips, thiab caprolactam. Cov khoom siv-xav tau qhov sib txawv tau ua rau cov nqi lag luam nce ntxiv.
Butadiene, ib qho tseem ceeb ntawm cov khoom siv raw rau PA66, tau pom muaj qhov nce siab heev. Thaum kawg ntawm lub Peb Hlis 2026, tus nqi lag luam hauv tsev ntawm butadiene hauv Suav teb tau tshaj 15,600 yuan ib tuj, nrog rau qee lub lag luam hais txog 17,000 yuan / ton- nce ntxiv ntau dua 102%, ntaus cuaj- xyoo siab txij li nruab nrab-2017.
Cuaj caum feem pua ntawm butadiene yog muab los ntawm naphtha cracking khoom. Kev nce nqi roj av ncaj qha tau thawb nws cov nqi tsim khoom. Ua ke nrog kev saib xyuas kom zoo ntawm cov nroj tsuag petrochemical thiab kev ceeb toom los ntawm kev lag luam hauv qab cov roj hmab thiab cov yas, ntau yam tau sib sau ua ke ua rau tus nqi nce siab.
Tsav los ntawm cov qauv no, tus nqi ntawm ntau tshaj li ib puas lub teb chaws cov ntaub ntawv raw khoom tau nce ntxiv. Ferrous sulfate pom ib lub lim tiam nce ntawm 42% thiab ib xyoos - ntawm - xyoo nce ntawm 112%. Diethylene glycol, hydrochloric acid, thiab 2-hydroxyethyl acrylate tag nrho sawv los ntawm 28%. Roj teeb -qib/kev lag luam- qib lithium carbonate, bromine, thiab trimethylolpropane tau sau tseg cov nyiaj tau los txhua lub lim tiam txij li 10% mus rau 15%. Kev lag luam yas thiab roj hmab kuj tau nce siab, nrog ABS nce 10.23% lub hli- ntawm- hli thiab PC 5.21% lub hli-rau-hli, thaum cov roj hmab nitrile thiab cov roj hmab ntuj tau nce tsis tu ncua.
Polyurethane kev lag luam saw tau tshwm sim los ua cov haujlwm tseem ceeb cuam tshuam los ntawm qhov nce nqi no. Txij li thaum Lub Ib Hlis 2026, tus nqi nce ntxiv ntawm polymeric MDI thiab ntshiab MDI hauv kev ua lag luam tau ze li 40%, uas tsis muaj qhov pom tseeb ntawm kev thim rov qab txog tam sim no.
Ntau yam tseem ceeb suav nrog TDI, hloov pauv tau ua npuas ncauj polyether, thiab TPU tau nce ntau dua 20% hauv rau lub hlis dhau los. CASE polyether coj cov txiaj ntsig nrog ze li ntawm 30% nce ntxiv, thaum polyester polyol thiab spandex ob leeg tau nce ntau dua 26%. Kev txhawb nqa cov khoom xws li hloov pauv tau ua npuas ncauj silicone roj, polyurethane catalysts, thiab polyurethane resins kuj nce los ntawm kwv yees li 22%, tawm hauv yuav luag tsis muaj cov khoom lag luam nyob thoob plaws tag nrho polyurethane industrial ecosystem.
Tus nqi nthwv dej tau xa mus rau tag nrho cov saw hlau los ntawm cov tshuaj fibers mus rau engineering plastics, hluavtaws roj hmab rau polyurethane, thiab cov tshuaj yooj yim rau cov khoom siv hluav taws xob tshiab. Cov tuam txhab lag luam hauv qab ntawm cov khoom siv tsheb, textiles thiab khaub ncaws, cov khoom siv hluav taws xob, thiab cov khoom siv hauv tsev niaj hnub tau ntsib cov nqi pheej yig, vim tias kev lag luam cuam tshuam nrog ob qho kev sib tw ntawm kev tswj hwm tus nqi thiab kev ruaj ntseg.
Qhov kev hloov pauv ntawm cov khoom siv tshuaj lom neeg tus nqi nce siab yog qhov tseem ceeb ntawm qhov tshwm sim ntawm qhov cuam tshuam ntawm plaub yam: kev hloov pauv ntawm cov nqi hluav taws xob thoob ntiaj teb, kev tsis sib haum xeeb ntawm thaj chaw, kev cuam tshuam hauv cov khoom siv tseem ceeb, thiab kev saib xyuas kev lag luam zoo. Qhov ntau tshaj 102% surge nyob rau hauv butadiene tau ua lub hauv paus ntsiab lus, nrog cov nylon thiab polyurethane industrial chains raws li tus nqi tseem ceeb -hiking sectors, uas nyob rau hauv lem tsav tsheb hla -- pawg thawj coj sawv cev ntawm ntau tshaj ib puas khoom tshuaj.
Qhov no tsis yog tsuas yog tus nqi volatility rau ib yam khoom xwb, tab sis ib qho kev hloov kho loj ntawm cov khoom siv -xav tau tus qauv nyob rau hauv lub ntiaj teb no chemical kev lag luam saw. Nws kuj tseem qhia txog cov ntsiab lus mob ntawm kev lag luam tshuaj lom neeg hauv tsev, uas yog kev cia siab rau sab nraud ntawm cov khoom siv raw khoom tseem ceeb thiab tsis muaj peev xwm ua rau muaj kev pheej hmoo hauv cov saw hlau.
