1. Makeke honua.
I ka ʻoihana automotive, ʻo ka māmā a me ka electrification nā kumu nui e alakaʻi i ka ulu ʻana o ka noi PBT.I nā makahiki i hala iho nei, ʻoiai ua liʻiliʻi a ʻoi aku ka paʻakikī o nā mīkini, a ua hoʻohui ʻia nā mea hana hou aku no ka maʻalahi a me ka hōʻoluʻolu o ka poʻe kaʻa, ua hoʻonui ka hoʻohana ʻana i nā mea uila i nā kaʻa, a ua ʻike ʻia ka PBT i hoʻohana ʻia i nā mea hoʻohui a me nā ʻōnaehana hoʻāla.2021, e helu ʻo PBT ma kahi o 40% o ka hoʻohana ʻana i ka ʻoihana automotive, i hoʻopaʻa ʻia ma ʻAmelika ʻAmelika, ʻEulopa, ka ʻāina ʻo Kina a me Iapana.

I ka ʻāpana uila a me ka uila, ʻo ka miniaturization ka mea nui e alakaʻi i ka ulu ʻana o ka noi no PBT.ʻo ke kahe hoʻoheheʻe kiʻekiʻe o nā resins PBT e maʻalahi i ka hana ʻana i nā ʻāpana liʻiliʻi a paʻakikī.I nā makahiki i hala iho nei, ʻo ka piʻi nui ʻana o ka noi no nā mea hoʻohui ʻia i ka paia lahilahi e hoʻohana i ka lewa ma nā papa kaapuni i paʻi ʻia i ka ulu ʻana o ka PBT ma ka ʻāpana uila a me ka uila.E ʻike ʻo 2021 i ka hoʻohana ʻana i ka PBT i ka ʻāpana uila a me ka uila e helu ana ma kahi o 33%.

Ma waho aʻe o nā ʻāpana maʻamau e like me ka automotive a me nā mea uila, e ʻike pū ʻo PBT i kahi lumi no ka ulu ʻana i ka ʻāpana kukui.Ke hoʻohana nei ʻo Mainland China, ʻAmelika, ʻEulopa a me kekahi mau mākeke ʻē aʻe i nā CFL e hoʻopau i nā kukui incandescent kuʻuna, a hoʻohana nui ʻia nā PBT ma ke kumu a me nā ʻāpana reflector o CFL.

Manaʻo ʻia ka piʻi ʻana o ka noi PBT honua ma ka awelika makahiki o 4% a i 1.7 miliona tonnes e 2025. ʻO ka ulu ʻana e ulu nui mai nā ʻāina / mau ʻāina.Manaʻo ʻia ʻo Asia Hikina Hema e ulu ma kahi kiʻekiʻe o ka makahiki ma kahi o 6.8%, a ukali ʻia e India ma kahi o 6.7%.Ma nā ʻāina makua e like me ʻEulopa a me ʻAmelika ʻĀkau, manaʻo ʻia ka ulu ʻana o 2.0% a me 2.2% i kēlā me kēia makahiki.

2. Makeke kūloko.
I ka makahiki 2021, e hoʻopau ʻo Kina i 728,000 tonnes o PBT, me ka helu wili no ka hapa kiʻekiʻe loa (41%), a ukali ʻia e ka ʻenehana ʻenekinia plastics / machinery (26%) a me nā mea uila a me nā mea hana (16%).Manaʻo ʻia ka hoʻohana ʻana o PBT o Kina e hiki i 905,000 tonnes e 2025, me ka awelika o ka ulu ʻana o ka makahiki he 5.6% mai 2021 a 2025, me ka ulu ʻai ʻana e alakaʻi nui ʻia e ka ʻoihana automotive / mīkini.

Māhele milo
ʻOi aku ka maikaʻi o ka pulupulu PBT a ʻoi aku ka maikaʻi o kona elastic recovery rate ma mua o ka polyester a me ka nylon, i kūpono no ka hana ʻana i nā lole ʻauʻau, nā lole gymnastic, stretch denim, ski trousers, medical bandges, etc. , a ua manaʻo ʻia ke koi ʻana no ka PBT no nā noi wili e ulu ma kahi o 2.0% mai 2021 a 2025.

ʻO nā plastik no nā kaʻa a me nā mīkini
E hoʻonui ka hana kaʻa a me nā kūʻai aku o Kina i kēlā me kēia makahiki ma 2021, e hoʻopau ana i ka emi ʻana o ʻekolu mau makahiki mai 2018. He mea kupaianaha ka mākeke kaʻa kaʻa hou, me ka hoʻonui ʻana o ka hana kaʻa kaʻa hou o Kina e 159% makahiki-ma-makahiki ma 2021 a ke manaʻo nei e hoʻomau i ka ulu ikaika i ka wā e hiki mai ana, me ke koi ʻana no ka PBT i nā ʻenehana ʻenehana automotive a me nā ʻāpana mīkini e ulu ana ma kahi o 13% mai 2021 a 2025.

Nā kahua uila a me ka uila
E hoʻomau ka hoʻomohala wikiwiki ʻana o nā mākeke uila, kamepiula a me nā mākeke kamaʻilio Kina, e alakaʻi i ka ulu paʻa o nā mea hoʻohui a me nā wahi noiʻi ʻē aʻe, i hui pū ʻia me ka ulu nui ʻana o nā kukui mālama ikehu, koi ʻia ke koi no ka PBT i ka ʻoihana uila a me nā lako uila. 5.6% mai 2021 a 2025.

3. E lohi paha ka hoʻonui ʻana o ka hana PBT o Kina
ʻOi aku paha ka nui o ka ulu ʻana i waho ma mua o ka ulu ʻana o ka meaʻai

I ka makahiki 2021, e pili ana ka mana hana PBT honua ma kahi o 2.41 miliona tonnes / makahiki, ka nui ma Kina, ʻEulopa, Iapana a me ka US, me ka helu ʻana o Kina no 61% o ka mana hana.

ʻAʻole i hoʻonui nā mea hana multinational i nā resins base PBT i nā makahiki i hala iho nei, akā ua hoʻonui i ka mana no ka PBT composite a me nā thermoplastics ʻenehana ʻē aʻe ma Kina a me India.E hoʻopili ʻia nā hoʻohui mana PBT e hiki mai ana ma Kina a me ka Middle East, me ka ʻole o nā hoʻolālā hoʻonui i hōʻike ʻia ma nā wahi ʻē aʻe no ʻekolu makahiki.

Hoʻonui ka PBT Kina i ka 1.48 miliona tonnes / makahiki ma ka hopena o 2021. ʻO nā mea komo hou e komo pū me Sinopec Yizheng Chemical Fiber, Zhejiang Meiyuan New Material a me Changhong Bio.Ke lohi nei ka hoʻonui ʻana o ka mana PBT ma Kina i nā makahiki ʻelima e hiki mai ana, me Henan Kaixiang, He Shili a me Xinjiang Meike wale nō i hōʻike i nā hoʻolālā hoʻonui.

I ka makahiki 2021, he 863,000 tonnes ka hana PBT o Kina, me ka awelika o ka hoʻomaka ʻana o ka ʻoihana he 58.3%.I ka makahiki hoʻokahi, ua hoʻokuʻu aku ʻo Kina i 330,000 tonnes o ka resin PBT a lawe mai i 195,000 tonnes, i hopena i ka hoʻokuʻu ʻana aku o 135,000 tonnes.2017-2021 Ua piʻi aʻe ka nui o ka PBT o Kina i ka awelika makahiki o 6.5%.

Manaʻo ia mai 2021-2025, e piʻi iki ka piʻi ʻana o ka nui o ka hoʻokuʻu ʻana aku o Kina ma mua o ka ulu ʻana o ka hoʻohana ʻana, e hoʻolōʻihi ka hoʻonui ʻana i ka mana hana PBT home a e piʻi ka nui o ka hoʻomaka ʻana o ka ʻoihana ma kahi o 65. %.
