1. Msika wapadziko lonse lapansi.
M'gawo lamagalimoto, kuyatsa ndi kuyika magetsi ndizinthu zazikulu zomwe zikuyendetsa kukula kwa kufunikira kwa PBT.M'zaka zaposachedwa, pamene injini zakhala zing'onozing'ono komanso zovuta kwambiri, ndipo zida zowonjezera zawonjezeredwa kuti zikhale zosavuta komanso zotonthoza, kugwiritsa ntchito zipangizo zamagetsi m'magalimoto kwawonjezeka, ndipo PBT yogwiritsidwa ntchito muzitsulo ndi machitidwe oyaka moto yawona kukula kwakukulu.2021, PBT idzawerengera pafupifupi 40% yazakudya zamagalimoto, zomwe zimakhazikika ku North America, Europe, China ndi Japan.

Pagawo lamagetsi ndi zamagetsi, miniaturization ndiye chinthu chachikulu chomwe chikuyendetsa kukula kwakufunika kwa PBT.kusungunuka kwapamwamba kwa PBT resins kumapangitsa kuti zikhale zosavuta kuzipanga kukhala zigawo zing'onozing'ono, zovuta.M'zaka zingapo zapitazi, kufunikira kwakukula kwa zolumikizira zokhala ndi mipanda yopyapyala kuti zigwiritse ntchito malo pama board osindikizidwa kwachititsa kukula kwa PBT mugawo lamagetsi ndi zamagetsi.2021 iwona kugwiritsidwa ntchito kwa PBT m'gawo lamagetsi ndi zamagetsi kuwerengera pafupifupi 33%.

Kuphatikiza pa magawo wamba monga zida zamagalimoto ndi zamagetsi, PBT iwonanso malo ena oti ikule mu gawo lowunikira.Mainland China, US, Europe ndi misika ina ikugwiritsa ntchito ma CFL kuthetsa nyali zachikhalidwe, ndipo ma PBT amagwiritsidwa ntchito makamaka m'magawo oyambira ndi owunikira a CFL.

Zofuna za PBT zapadziko lonse zikuyembekezeka kuwonjezeka pa avareji ya 4% mpaka matani 1.7 miliyoni pofika chaka cha 2025. Kukula kudzachokera makamaka m'mayiko / madera omwe akutukuka kumene.Kumwera chakum'mawa kwa Asia akuyembekezeka kukula kwambiri pachaka pafupifupi 6.8%, kutsatiridwa ndi India pafupifupi 6.7%.M'madera okhwima monga Europe ndi North America, kukula kwa 2.0% ndi 2.2% pachaka kumayembekezeredwa motsatira.

2. Msika wapakhomo.
Mu 2021, China idzadya matani 728,000 a PBT, ndi ma spinning account omwe amagawana kwambiri (41%), kutsatiridwa ndi gawo lamapulasitiki / makina opanga magalimoto (26%) ndi zamagetsi ndi zida (16%).Kugwiritsiridwa ntchito kwa PBT ku China kukuyembekezeka kufika matani 905,000 pofika 2025, ndikukula kwapakati pachaka kwa 5.6% kuyambira 2021 mpaka 2025, ndikukula kwa ogwiritsa ntchito makamaka moyendetsedwa ndi gawo lamagalimoto / makina.

Gawo lozungulira
PBT fiber imakhala ndi kusungunuka bwino ndipo kuchira kwake kuchira kumakhala bwino kuposa poliyesitala ndi nayiloni, yomwe ili yoyenera kupanga masuti osambira, kuvala masewera olimbitsa thupi, kutambasula denim, mathalauza otsetsereka, mabandeji azachipatala, ndi zina zotero. Kufuna msika kudzakula kwambiri mtsogolomu. , ndipo kufunikira kwa PBT pamapulogalamu ozungulira akuyembekezeka kukula pafupifupi 2.0% kuyambira 2021 mpaka 2025.

Mapulasitiki opanga magalimoto ndi makina
Kupanga ndi kugulitsa magalimoto ku China kudzawonjezeka chaka ndi chaka mu 2021, ndikuthetsa kuchepa kwa zaka zitatu kuyambira 2018. Msika watsopano wamagalimoto amagetsi ndiwopambana kwambiri, pomwe magalimoto aku China akuwonjezeka ndi 159% pachaka mu 2021. akuyembekezeka kukhalabe ndi kukula kwakukulu m'tsogolomu, ndi kufunikira kwa PBT m'mapulasitiki opanga magalimoto ndi gawo lamakina kukukula pafupifupi 13% kuyambira 2021 mpaka 2025.

Zamagetsi ndi zamagetsi
Misika yaku China yamagetsi, makompyuta ndi mauthenga olumikizirana ipitiliza kukula mwachangu, ndikupangitsa kukula kokhazikika kwa zolumikizira ndi madera ena ogwiritsira ntchito, komanso kutchuka kwa nyali zopulumutsa mphamvu, kufunikira kwa PBT m'gawo lamagetsi ndi zida zamagetsi kukuyembekezeka kukula. 5.6% kuyambira 2021 mpaka 2025.

3. Kukula kwapang'onopang'ono kwa PBT ku China kumatha kuchepa
Chiwopsezo cha kukula kwa katundu wogulitsa kunja chikhoza kukhala chokwera kuposa momwe anthu amagwiritsira ntchito

Mu 2021, mphamvu yapadziko lonse lapansi yopanga PBT idzakhala pafupifupi matani 2.41 miliyoni / chaka, makamaka ku China, Europe, Japan ndi US, pomwe China ikuwerengera 61% ya mphamvu zopanga.

Opanga m'mayiko osiyanasiyana sanawonjezere mphamvu za PBT base resins m'zaka zaposachedwa, koma awonjezera mphamvu ya PBT yophatikizika ndi ma engineering thermoplastics ena ku China ndi India.Zowonjezereka zamtsogolo za PBT zidzakhazikika ku China ndi Middle East, popanda ndondomeko zowonjezera m'madera ena kwa zaka zitatu.

China PBT mphamvu imakwera kufika matani 1.48 miliyoni/chaka pofika kumapeto kwa 2021. Olowa nawo atsopano akuphatikizapo Sinopec Yizheng Chemical Fiber, Zhejiang Meiyuan New Material ndi Changhong Bio.Kukula kwa mphamvu ya PBT ku China kukuchepa m'zaka zisanu zikubwerazi, ndi Henan Kaixiang, He Shili ndi Xinjiang Meike okha omwe adanena kuti ali ndi ndondomeko zowonjezera.

Mu 2021, kupanga kwa PBT ku China kudzakhala matani 863,000, ndi kuchuluka kwamakampani oyambira 58.3%.M’chaka chomwecho, dziko la China linatumiza kunja matani 330,000 a PBT resin ndi kuitanitsa matani 195,000, zomwe zinachititsa kuti matani 135,000 atumizidwe kunja.2017-2021 kuchuluka kwa PBT ku China kudakula pa avareji pachaka cha 6.5%.

Zikuyembekezeka kuti kuyambira 2021-2025, kuchuluka kwa kuchuluka kwa malonda aku China kudzakhala kokwera pang'ono kuposa kuchuluka kwa anthu omwe amadya, kukulitsa mphamvu zopangira zapakhomo za PBT kudzatsika pang'onopang'ono ndipo kuchuluka kwamakampani oyambira kumakwera mpaka 65. %.
