Polyurethane (PU), tseem hu ua polyurethane, yog cov khoom siv organic polymer synthesized los ntawm cov tshuaj tiv thaiv ntawm polyisocyanates (OCN-R-NCO) thiab polyols (HO-R-OH). Vim tias muaj ntau pawg amino ester (ua luv li amino esters) hauv cov qauv molecular, nws hu ua polyurethane.
Polyurethane cov ntaub ntawv muaj kev ua tau zoo heev thiab yog irreplaceable
Polyurethane cov ntaub ntawv muaj kev ua tau zoo heev thiab yog irreplaceable. Piv nrog rau cov roj hmab, polyurethane muaj kev hnav zoo dua thiab tiv thaiv kev txiav thiab tawg. Piv nrog rau cov hlau thiab yas, polyurethane lub suab rwb thaiv tsev thiab hnav tsis kam yog qhov tshwj xeeb tshaj plaws.
Kev lag luam polyurethane loj yuav ncav cuag 93.1 billion US dollars los ntawm 2025
Raws li tsab ntawv ceeb toom tshiab los ntawm Kev Tshawb Fawb Ntiaj Teb Kev Lag Luam, polyurethane kev lag luam loj yog kwv yees li $ 59.5 nphom hauv xyoo 2018, thiab xav tias yuav ncav cuag $ 93.1 nphom los ntawm 2025, nrog kev loj hlob txhua xyoo ntawm 5.8% thaum lub sijhawm kwv yees.
Kev tsim khoom thiab muag khoom ntawm polyurethane hauv Suav teb tseem loj hlob sai
Txij li thaum xyoo pua 21st, kev tsim thiab muag khoom ntawm polyurethane hauv Suav teb tau txuas ntxiv mus sai. Hauv xyoo 2019, Tuam Tshoj cov khoom lag luam polyurethane tau nce mus txog 13.66 lab tons, suav txog li 45% ntawm tag nrho cov khoom tsim tawm, thiab kev siv cov khoom siv polyurethane mus txog 11.85 lab tons. Tuam Tshoj tau dhau los ua tus tsim khoom loj ntawm polyurethane thiab yog ib lub lag luam loj rau polyurethane.
Polyurethane muaj peev xwm ua lag luam loj heev yav tom ntej
Tam sim no, kev tsim cov khoom lag luam hauv qab polyurethane xws li cov khoom siv hauv tsev, spandex, hluavtaws tawv, thiab cov tsheb ua ntej. Kev ntsuas xws li kev txhawb nqa dej-raws li txheej txheej thiab ua raws li cov cai tshiab txuag hluav taws xob rau cov tsev yog txhua yam ua rau muaj kev lag luam loj rau kev lag luam polyurethane. Nws cia siab tias los ntawm 2025, qhov kev siv ntawm cov khoom lag luam polyurethane yuav ncav cuag 18.28 lab tons, nrog rau kev loj hlob txhua xyoo ntawm 7.8% txij xyoo 2020 txog 2025.
