Kev siv
1,4-Butanediol (BDO)yog ib qho tseem ceeb organic tshuaj raw khoom siv nrog ntau cov kev siv. Cov kev ua ntaub ntawv tseem ceeb yog raws li hauv qab no:
Kev tsim cov khoom lag luam polyester
- Rau cov synthesis ntawm polybutylene Terephthalate (PBT): PBT yog ib qho zoo thermoplastic polyester Engineering Yas. Nws muaj cov kws kho tshuab zoo, kev tshuaj lom zoo heev corrosion, thiab rwb thaiv hluav taws xob zoo nkauj, thiab muaj zog seem ruaj khov. Nws yog dav siv nyob rau hauv cov khoom siv hluav taws xob thiab hluav taws xob ua vaj tse los tsim ntau yam hluav taws xob hauv tsev thiab txuas. Qee qhov chaw hauv kev lag luam tsheb, xws li lub qhov rooj tsheb thiab cov pob tw, kuj yog cov tsim kev siv PBT cov ntaub ntawv.
- Rau kev tsim cov thermoplastic polyurethane (tpu sib xyaw ua ke ntawm cov roj hmab nrog cov txheej txheem yooj yim ntawm cov yas. Nws yog hnav-resistant, roj-resistant, thiab txias-resistant. Nws yog feem ntau siv los ua khau yas, kav dej, xaim thiab cable sheaths, endering cov khoom siv tau zoo thiab lub zog tensile.
Siv thiab ua γ-Butyrolactone thiab N-Methylpyrrolidone (NMP)
- γ-Butyrolactone: Nws yog qhov zoo tshaj plaws-boiling-point daws nrog muaj zog solubility, muaj cov nyhuv zoo ntawm cov organic sib txuas thiab cov polymers. Nws yog dav siv nyob rau hauv txheej, number case, thiab luam ntawv thiab dyeing kev lag luam. Nws tseem yog cov khoom siv pib rau cov hluavtaws thiab cov khoom siv tshuaj lom neeg thiab cov khoom siv nplua nrog cov qauv tshwj xeeb thiab cov haujlwm tuaj yeem muab tau muab muab tau los ntawm tom qab.
- N-methylprolidone: nws yog polar agoric kuab, muaj peev xwm zoo tshaj plaws muaj peev xwm rau ntau cov organic organic, inorger cov ntaub ntawv. Nws yog qhov tseem ceeb heev nyob rau hauv kev tsim cov roj teeb lithium, siv los yaj cov khoom siv, hluav taws xob, hluav taws xob ntxuav, thiab rho tawm cov txheej txheem sib cais.
Rau cov synthesis ntawm tetrahydrofuran (thf): tetrahydrofuran yog ib feem ntau siv cov kuab tshuaj zoo heev, muaj solubility zoo rau ntau cov organic cov organic. Hauv cov khoom siv hluav taws xob hauv nruab nrog cev thiab cov tshuaj tiv thaiv kev tsim khoom siv tshuaj lom neeg, feem ntau nws siv los ua kev daws teeb meem los txhawb kev txhawb nqa cov kev txhawb nqa. Tsis tas li ntawd, nws tseem yog cov khoom siv raw rau cov synthesis ntawm polytetrahydrofuran (ptmeg). PTMEG is used to produce spandex fibers and polyurethane elastomers, providing a highly elastic material basis for the textile, high-end sportswear, and other industries.
Cov ntawv thov hauv cov ntawv kho mob: 1,4-butanediol tuaj yeem siv los ua cov tshuaj nruab nrab ntawm qee cov tshuaj molecules. Piv txwv li, nyob rau hauv cov kauj ruam synthesis ntawm qee cov tshuaj noj tshuaj thiab tshuaj tua kab mob, nws cov tshuaj tiv thaiv kev tshawb fawb, kev txhim kho, thiab kev tsim cov tshuaj tshiab.
Ntim thiab Thauj Khoom
25kg / nruas lossis raws li cov neeg siv khoom.
Belongs rau cov khoom lag luam thiab tuaj yeem xa los ntawm dej hiav txwv thiab huab cua
Khaws thiab Cia
Txee lub neej: 24 lub hlis txij hnub ua lag luam hauv cov khoom ntim tsis tau ntim rau hauv qhov chaw txias txias tawm ntawm lub hnub ncaj qha, dej.
Qhov chaw ua kom lub tsev rau khoom, tsis muaj kub kom qhuav ziab, sib cais los ntawm oxidants, acids.
