Kev Siv
1,4-Butanediol (BDO)yog ib qho khoom siv tseem ceeb ntawm cov tshuaj lom neeg organic nrog ntau yam kev siv. Cov kev siv tseem ceeb yog raws li nram no:
Kev tsim cov khoom polyester
- Rau kev tsim cov polybutylene terephthalate (PBT): PBT yog cov yas thermoplastic polyester engineering zoo heev. Nws muaj cov khoom siv kho tshuab zoo, tiv taus kev xeb tshuaj zoo heev, rwb thaiv hluav taws xob zoo, thiab ruaj khov. Nws yog siv dav hauv kev lag luam hluav taws xob thiab cov khoom siv hluav taws xob los tsim ntau yam khoom siv hluav taws xob thiab cov khoom sib txuas. Qee qhov chaw hauv kev lag luam tsheb, xws li lub qhov rooj tsheb thiab lub bumpers, kuj feem ntau tsim los ntawm kev siv cov ntaub ntawv PBT.
- Rau kev tsim cov thermoplastic polyurethane (TPU): TPU muab cov roj hmab ua ke nrog cov yas uas yooj yim ua. Nws tiv taus kev hnav, tiv taus roj, thiab tiv taus txias. Nws feem ntau siv los ua cov khau hauv qab, cov kav dej, cov hlau thiab cov hlua khi, cov siv conveyor kev lag luam, thiab lwm yam. 1,4-Butanediol yog cov khoom siv raw tseem ceeb rau kev tsim cov TPU, ua rau cov khoom muaj kev ywj pheej zoo thiab cov khoom tensile.
Kev tsim cov γ-butyrolactone thiab N-methylpyrrolidone (NMP)
- γ-butyrolactone: Nws yog ib qho tshuaj yaj uas kub heev nrog kev yaj zoo heev, muaj cov nyhuv yaj zoo rau ntau cov organic compounds thiab polymers. Nws yog siv dav hauv kev lag luam txheej, kua mem, thiab kev luam ntawv thiab zas xim. Nws tseem yog cov khoom siv pib rau kev tsim ntau yam txuj lom thiab tshuaj intermediates, uas ntau yam tshuaj zoo nrog cov qauv tshwj xeeb thiab kev ua haujlwm tuaj yeem tau txais tom qab.
- N-methylpyrrolidone: Nws yog ib qho tshuaj yaj polar aprotic, qhia txog kev yaj zoo heev rau ntau yam khoom siv tsis yaj organic, inorganic, thiab polymer. Nws yog qhov tseem ceeb heev hauv kev tsim cov roj teeb lithium, siv los yaj cov binders, cov khoom siv electrode, thiab lwm yam. Nws kuj muaj cov ntawv thov tseem ceeb hauv kev tsim tshuaj tua kab, kev ntxuav hluav taws xob, thiab kev rho tawm thiab kev sib cais.
Rau kev tsim cov tetrahydrofuran (THF): Tetrahydrofuran yog cov kuab tshuaj zoo heev uas siv ntau, muaj kev yaj zoo rau ntau yam khoom siv organic thiab synthetic. Hauv cov chaw soj nstuam organic synthesis thiab cov txheej txheem tshuaj lom neeg, nws feem ntau siv los ua cov kuab tshuaj los txhawb cov tshuaj tiv thaiv. Tsis tas li ntawd, nws tseem yog cov khoom siv raw rau kev tsim cov polytetrahydrofuran (PTMEG). PTMEG yog siv los tsim cov spandex fibers thiab polyurethane elastomers, muab cov khoom siv elastic heev rau cov ntaub, cov khaub ncaws ua si siab, thiab lwm yam lag luam.
Cov ntawv thov hauv kev kho mob: 1,4-Butanediol tuaj yeem siv ua cov tshuaj nruab nrab los koom nrog kev tsim cov tshuaj molecule. Piv txwv li, hauv cov kauj ruam tsim cov tshuaj steroid thiab tshuaj tua kab mob, nws cov haujlwm tshuaj lom neeg yog siv los tsim thiab hloov kho cov qauv ntawm cov tshuaj molecule, pab txhawb kev tshawb fawb, kev txhim kho, thiab kev tsim cov tshuaj tshiab.
Ntim thiab Xa Khoom
25KG / Nruas los yog raws li cov neeg siv khoom xav tau.
Yog cov khoom siv dav dav thiab tuaj yeem xa los ntawm dej hiav txwv thiab huab cua
Khaws cia thiab khaws cia
Lub neej txee: 24 lub hlis txij li hnub tsim khoom hauv cov ntim khoom tsis tau qhib khaws cia rau hauv qhov chaw txias thiab qhuav kom tsis txhob raug tshav ntuj ncaj qha, dej.
Lub tsev rau khoom muaj cua nkag, ziab kom qhuav kub tsawg, Sib cais ntawm cov tshuaj oxidants, cov kua qaub.
