1. Imakethe yamazwe ngamazwe.
Emkhakheni wezimoto, ukukhanya nokufakwa kukagesi yizona zinto ezihamba phambili eziqhuba ukukhula kwesidingo se-PBT.Eminyakeni yamuva, njengoba izinjini ziye zaba zincane futhi ziyinkimbinkimbi, futhi imishini eyengeziwe yengezwe ukuze kube lula futhi kududuze abagibeli, ukusetshenziswa kwemishini kagesi ezimotweni kuye kwanda, futhi i-PBT esetshenziselwa izixhumi nezinhlelo zokuthungela ibone ukukhula okuphezulu.Ngo-2021, i-PBT izobalelwa cishe u-40% wokusetshenziswa emkhakheni wezimoto, ogxile eNyakatho Melika, eYurophu, ezweni laseChina naseJapane.

Emkhakheni kagesi nogesi, i-miniaturization iyisici esiyinhloko esiqhuba ukukhula kwesidingo se-PBT.ukuncibilika okuphezulu kwama-resin e-PBT kwenza kube lula ukucubungula zibe izingxenye ezincane, eziyinkimbinkimbi.Eminyakeni embalwa edlule, isidingo esikhulayo sezixhumi ezinezindonga ezincane ukuze kusetshenziswe isikhala kumabhodi esekethe aphrintiwe siqhubekisele phambili ukukhula kwe-PBT emkhakheni kagesi nogesi.U-2021 uzobona ukusetshenziswa kwe-PBT emkhakheni kagesi nogesi kubala cishe u-33%.

Ngokungeziwe emikhakheni evamile efana nemishini yezimoto nekagesi, i-PBT izophinde ibone indawo ethile yokukhula emkhakheni wokukhanyisa.I-Mainland China, i-US, i-Europe kanye nezinye izimakethe zisebenzisa ama-CFL ukuze kucishwe amalambu endabuko e-incandescent, futhi ama-PBT asetshenziswa kakhulu ezingxenyeni eziyisisekelo nezibonisayo zama-CFL.

Isidingo se-PBT yomhlaba wonke kulindeleke ukuthi sikhule ngesilinganiso sonyaka esiphakathi kuka-4% kuya ku-1.7 wamathani ayizigidi ngo-2025. Ukukhula kuzovela ikakhulukazi emazweni/izifunda ezisathuthuka.INingizimu-mpumalanga ye-Asia kulindeleke ukuthi ikhule ngenani eliphakeme kakhulu lonyaka elicishe libe ngu-6.8%, ilandelwe yi-India cishe ngo-6.7%.Ezifundeni ezivuthiwe njengaseYurophu naseNyakatho Melika, amazinga okukhula ka-2.0% no-2.2% ngonyaka alindeleke ngokulandelana.

2. Imakethe yasekhaya.
Ngo-2021, i-China izosebenzisa amathani angu-728,000 e-PBT, nge-spinning accounting yesabelo esikhulu kunazo zonke (41%), kulandelwa umkhakha wepulasitiki/imishini yobunjiniyela bezimoto (26%) kanye nogesi nezinto zikagesi (16%).Ukusetshenziswa kwe-PBT yaseShayina kulindeleke ukuthi kufinyelele kumathani angama-905,000 ngo-2025, ngesilinganiso sokukhula saminyaka yonke esingu-5.6% kusukela ngo-2021 kuya ku-2025, nokukhula kokusetshenziswa okuqhutshwa ikakhulukazi umkhakha wezimoto/wemishini.

Umkhakha wokuphotha
Ifayibha ye-PBT inokunwebeka okuhle futhi izinga layo lokululama elinwebekayo lingcono kunele-polyester nenayiloni, elifanele ukwenza amasudi okubhukuda, ukugqokwa kwe-gymnastic, i-stretch denim, amabhulukwe e-ski, amabhandeshi ezokwelapha, njll. Isidingo semakethe sizokhula kancane esikhathini esizayo. , futhi isidingo se-PBT sokuphotha izinhlelo zokusebenza kulindeleke ukuthi sikhule ngesilinganiso esingaba ngu-2.0% kusukela ngo-2021 kuya ku-2025.

Ubunjiniyela bepulasitiki bezimoto nemishini
Ukukhiqizwa nokudayiswa kwezimoto zaseShayina kuzokwenyuka unyaka nonyaka ngo-2021, kuqede ukwehla kweminyaka emithathu kusukela ngo-2018. Imakethe yezimoto zamandla amasha iyamangalisa, njengoba ukukhiqizwa kwezimoto ezintsha zaseChina kukhuphuke ngo-159% unyaka nonyaka ngo-2021 futhi kulindeleke ukuthi igcine ukukhula okuqinile ngokuzayo, nesidingo se-PBT engxenyeni yamapulasitiki yobunjiniyela bezimoto nengxenye yemishini sikhula ngenani elicishe libe ngu-13% ukusuka ngo-2021 kuya ku-2025.

Izinkundla zikagesi nezikagesi
Izimakethe zase-China ze-electronics, computer kanye nezokuxhumana zizogcina intuthuko esheshayo, okuholela ekukhuleni okuzinzile kwezixhumi nezinye izindawo zokufaka izicelo, okuhambisana nokuthandwa okukhulayo kwezibani ezonga amandla, isidingo se-PBT emkhakheni we-electronics kanye nezinto zikagesi kulindeleke ukuthi zikhule 5.6% kusukela ngo-2021 kuya ku-2025.

3. Ukunwetshwa kwamandla okukhiqiza kwe-PBT yaseChina kungase kwehle
Izinga lokukhula lokuthekelisa lingase libe phezulu kunezinga lokukhula kokusetshenziswa

Ngo-2021, umthamo wokukhiqiza we-PBT womhlaba wonke uzoba cishe amathani ayizigidi ezingu-2.41 ngonyaka, ikakhulukazi e-China, eYurophu, eJapane nase-US, kanti i-China yenza u-61% womthamo wokukhiqiza.

Abakhiqizi bamazwe ngamazwe abazange bakhulise umthamo we-PBT base resins eminyakeni yamuva nje, kodwa baye bakhulisa umthamo we-PBT eyinhlanganisela namanye ama-thermoplastics yobunjiniyela e-China naseNdiya.Ukwengezwa kwamandla esikhathi esizayo e-PBT kuzogxilwa e-China naseMpumalanga Ephakathi, ngaphandle kwezinhlelo zokwandisa ezibikiwe kwezinye izifunda iminyaka emithathu.

Umthamo we-PBT wase-China ukhuphuka ufinyelele kumathani ayizigidi ezingu-1.48/ngonyaka ekupheleni kuka-2021. Abasanda kungena bafaka i-Sinopec Yizheng Chemical Fiber, i-Zhejiang Meiyuan New Material kanye ne-Changhong Bio.Ukunwetshwa komthamo we-PBT e-China kwehla kancane eminyakeni emihlanu ezayo, u-Henan Kaixiang, u-He Shili kanye no-Xinjiang Meike kuphela ababike ukuthi banezinhlelo zokunweba.

Ngo-2021, ukukhiqizwa kwe-PBT yase-China kuzoba amathani angu-863,000, ngesilinganiso sokuqalwa kwemboni esimaphakathi esingu-58.3%.Ngawo lowo nyaka, i-China yathumela ngaphandle amathani angu-330,000 e-PBT resin futhi yangenisa amathani ayi-195,000, okuholele ekuthengisweni kwengqikithi yamathani ayi-135,000.2017-2021 umthamo wokuthunyelwa kwe-PBT yaseChina ukhule ngesilinganiso sonyaka esimaphakathi esingu-6.5%.

Kulindeleke ukuthi kusukela ngo-2021-2025, izinga lokukhula komthamo wokuthunyelwa kwe-China lizoba phezulu kancane kunezinga lokukhula lokusetshenziswa, ukwanda kwamandla okukhiqiza we-PBT yasekhaya kuzokwehla futhi izinga lokuqalwa kwezimboni lizokhuphuka lifinyelele cishe ku-65. %.
