1. Imarike yamazwe ngamazwe.
Kwicandelo leemoto, ukukhanya kunye nokufakelwa kombane zezona zinto ziqhuba ukukhula kwemfuno ye-PBT.Kwiminyaka yakutshanje, njengoko ii-injini ziye zaba zincinci kwaye ziyinkimbinkimbi, kwaye izixhobo ezininzi zongezwa ukuze kube lula kunye nokuthuthuzela abagibeli, ukusetyenziswa kwezixhobo zombane kwiimoto kuye kwanda, kwaye i-PBT esetyenziswe kwii-connectors kunye neenkqubo zokutshisa ibone ukukhula okuphezulu.I-2021, i-PBT iya kuphendula malunga ne-40% yokusetyenziswa kwicandelo leemoto, ezigxininiswe eMntla Melika, eYurophu, kwilizwe laseChina naseJapan.

Kwicandelo lombane kunye ne-elektroniki, i-miniaturization yeyona nto iphambili eqhuba ukukhula kwemfuno ye-PBT.ukuhamba okuphezulu kwe-melt ye-PBT resins kwenza kube lula ukuqhutyelwa kwiindawo ezincinci, ezinzima.Kwiminyaka embalwa edlulileyo, imfuno ekhulayo yeziqhagamshelo ezinodonga oluncinci ukusebenzisa indawo kwiibhodi zesekethe eziprintiweyo ziqhube ukukhula kwe-PBT kwicandelo lombane kunye ne-elektroniki.Ngo-2021 siza kubona ukusetyenziswa kwe-PBT kwicandelo lombane kunye ne-elektroniki malunga ne-33%.

Ukongeza kumacandelo aqhelekileyo afana neemoto kunye nezixhobo zombane, i-PBT iya kubona kwakhona indawo yokukhula kwicandelo lokukhanyisa.I-Mainland China, i-US, iYurophu kunye nezinye iimarike zisebenzisa ii-CFL ukuphelisa izibane zendabuko ze-incandescent, kwaye ii-PBTs zisetyenziswa kakhulu kwisiseko kunye neendawo zokubonisa ii-CFLs.

Imfuno ye-PBT yehlabathi kulindeleke ukuba inyuke kumyinge wonyaka we-4% ukuya kwi-1.7 yezigidi zeetoni ngo-2025. Ukukhula kuya kuvela ikakhulu kumazwe / iingingqi ezisaphuhlayo.UMzantsi-mpuma weAsia kulindeleke ukuba ukhule ngelona zinga liphezulu lonyaka malunga ne-6.8%, lilandelwa yiIndiya malunga ne-6.7%.Kwiingingqi ezikhulileyo ezifana neYurophu kunye noMntla Melika, izinga lokukhula kwe-2.0% kunye ne-2.2% ngonyaka lilindeleke ngokulandelelanayo.

2. Imarike yasekhaya.
Ngo-2021, i-China iya kusebenzisa iitoni ze-728,000 ze-PBT, kunye ne-spinning accounting yesabelo esiphezulu (41%), ilandelwa yi-automotive engineering plastics / machine sector (26%) kunye ne-electronics kunye nezixhobo zombane (16%).Ukusetyenziswa kwe-PBT yaseTshayina kulindeleke ukuba kufikelele kwiitoni ezingama-905,000 ngo-2025, kunye nesantya sokukhula sonyaka se-5.6% ukusuka kwi-2021 ukuya kwi-2025, kunye nokukhula kokusetyenziswa okubangelwa ikakhulu licandelo lezemoto / loomatshini.

Icandelo lokujikeleza
Ifayibha ye-PBT ine-elasticity entle kwaye izinga layo lokubuyiswa kwe-elastic lingcono kune-polyester kunye ne-nylon, efanelekile ukwenza iisuti zokuqubha, ukunxiba kwe-gymnastic, i-stretch denim, i-skib trousers, i-bandages zonyango, njl njl. Imfuno yemarike iya kukhula ngokuthe ngcembe kwixesha elizayo , kunye nemfuno ye-PBT yokujikeleza izicelo kulindeleke ukuba ikhule ngesantya malunga ne-2.0% ukusuka kwi-2021 ukuya kwi-2025.

Iiplastiki zobunjineli zeemoto kunye noomatshini
Ukuveliswa kweemoto zaseChina kunye nokuthengisa kuya kwandisa unyaka-ngonyaka kwi-2021, ukuphelisa ukuhla kweminyaka emithathu ukususela ngo-2018. Imarike yemoto yamandla entsha igqwesile, kunye nemveliso yemoto entsha yaseChina inyuka nge-159% ngonyaka kwi-2021 kwaye kulindeleke ukuba kugcinwe ukukhula olomeleleyo kwixesha elizayo, kunye nemfuno ye-PBT kwiiplastiki zobunjineli beemoto kunye necandelo loomatshini elikhula ngesantya esimalunga ne-13% ukusuka ngo-2021 ukuya ku-2025.

Iindawo zombane kunye nezombane
I-electronics, ikhompyutha kunye neemarike zonxibelelwano zaseTshayina ziya kugcina uphuhliso olukhawulezayo, olukhokelela ekukhuleni okuzinzile kwizihlanganisi kunye nezinye iindawo zesicelo, kunye nokuthandwa okukhulayo kwezibane zokulondoloza amandla, imfuno ye-PBT kwicandelo lombane kunye nezixhobo zombane kulindeleke ukuba zikhule. 5.6% ukusuka 2021 ukuya 2025.

3. Ukwandiswa kwamandla emveliso yePBT yaseTshayina kunokucotha
Izinga lokukhula kokuthunyelwa kwempahla kumazwe angaphandle linokuba phezulu kunesantya sokukhula kokusetyenziswa

Kwi-2021, amandla okuvelisa i-PBT yehlabathi jikelele aya kuba malunga ne-2.41 yezigidi zeetoni / ngonyaka, ngokukodwa e-China, eYurophu, eJapan nase-US, kunye ne-China i-akhawunti ye-61% yomthamo wokuvelisa.

Abavelisi bezizwe ngezizwe abanyuswanga umthamo we-PBT base resins kwiminyaka yakutshanje, kodwa baye banyusa umthamo we-PBT edibeneyo kunye nezinye ii-thermoplastics zobunjineli e-China naseIndiya.Ukongezwa kwamandla exesha elizayo e-PBT kuya kugxininiswa e-China naseMbindi Mpuma, kungekho zicwangciso zokwandisa ezichazwe kweminye imimandla iminyaka emithathu.

Umthamo we-PBT waseTshayina unyuka ukuya kwi-1.48 yezigidi zeetoni / ngonyaka ekupheleni kuka-2021. Abangenayo abatsha baquka iSinopec Yizheng Chemical Fiber, iZhejiang Meiyuan New Material kunye ne-Changhong Bio.Ukwandiswa komthamo we-PBT e-China kuncipha kwiminyaka emihlanu ezayo, kunye noHenan Kaixiang kuphela, uHe Shili kunye no-Xinjiang Meike babike ukuba banezicwangciso zokwandisa.

Ngo-2021, imveliso ye-PBT yase-China iya kuba yi-863,000 yeetoni, kunye ne-avareji yokuqalisa ishishini le-58.3%.Kwangalo nyaka, i-China yathumela ngaphandle i-330,000 yeetoni ze-PBT resin kwaye ingenisa iitoni ezingama-195,000, okubangele ukuthunyelwa ngaphandle kwe-135,000 yeetoni.I-2017-2021 i-PBT ye-PBT ye-PBT yokuthunyelwa kwemveliso ikhule kumyinge wonyaka we-6.5%.

Kulindeleke ukuba ukusuka ngo-2021 ukuya ku-2025, izinga lokukhula komthamo wokuthumela ngaphandle kweTshayina liya kuba phezulu kancinci kunesantya sokukhula sokusetyenziswa, ukwandiswa komthamo wemveliso ye-PBT yasekhaya kuya kuthotha kwaye inqanaba lokuqalisa ishishini liya kunyuka liye kuma-65. %.
