Cov Ntawv Thov
1. Polymer & Resin Ntau Lawm
Cov Monomer tseem ceeb rau synthesizes:
Polyesters (piv txwv, Poly (1,12-dodecanediol Terephthalate))
Polyurethanes (raws li cov tog plaub lossis txuas ntxiv)
Polycarbonates thiab polyamides
Imparts yooj, hydrophobicity, thiab tshuaj lom neeg mus rau cov khoom siv.
2. Txhaj tshuaj pleev ib ce thiab tus kheej
Siv hauv cov khoom tu tawv nqaij raws li:
Lub moo
Ntxim qhuas
Daim tawv nqaij txias
Nws ntev carbon saw muaj ib tug du, waxy xav thiab txhim kho cov dej noo kom ua haujlwm.
3. Cov roj nplua nyeem thiab cov tshuab yas
Muaj nuj nqi raws li kev siv roj roj biodarrant lossis nruab nrab hauv cov roj siv eserming.
Txhim kho cov plasticity thiab hloov kho kom yooj yim ntawm cov ntaub qhwv thiab hluavtaws.
4. Resive Intermediate
Ua raws li kev haus dej haus cawv rau cov kev tiv thaiv zoo li:
Kaum rau
Lub nkoj
Polycondensation
Ua rau cov khoom lag luam surfactants, cov nplaum, thiab txheej.
5. Biomedical Cov Ntaub Ntawv
Nws biocompatibility thiab demadability ua nws haum rau biomedical polymers siv nyob rau hauv:
Tswj cov tshuaj noj
Biodegradable sutures
Cov ntaub so ntswg kiav txhab
Cov txiaj ntsig
1. Hydrophobic saw nrog lub davhlau ya nyob
Ntev-saw (12-carbon) Backbast muab cov cim hydrophobic rau cov kev siv hluav taws xob thiab dej tiv thaiv.
Cov davhlau ya nyob twg -oh pab tau yooj yim incorporation rau hauv polymer tom qab.
2. Biodegradable thiab eco-phooj ywg
Siab ib qho kev ua tiav thiab ua rau nws haum rau Green Chemistry thiab cov ntaub ntawv muaj kev ruaj ntseg.
Feem ntau siv nyob rau hauv biodegradable polymers thiab tshuaj pleev ib ce vim nws cov tshuaj lom tsawg.
3. Thermal thiab mechanical kev ua tau zoo
Thaum siv nyob rau hauv cov polyesters lossis polyurethanes, nws txhim kho:
Thermal ruaj khov
Kev muaj zog
HYDRYTIC Kuj
4. Muaj ntau yam kev sib raug zoo
Tau tshaj ntau yam ntawm cov txheej txheem muaj:
Melt polymerization
Cov Hnyav-raws li hluavtaws
Kev Nyuaj Siab Kub
Tag
1,12-dodecanediol (CAS 5675-51-4) yog ib txoj kab linear nrog ntau cov ntawv thov thoob plaws cov ntaub ntawv, tshuaj pleev ib ce, thiab roj ciradadable cov ntaub ntawv. Nws cov saw alkyl ntev thiab davhlau ya nyob hauv pawg ua kom nws los ua cov synthesis ntawm kev hloov tau, ruaj, thiab tshuaj pollo. Tsis tas li ntawd, nws ua kom cov tawv nqaij xav tias thiab noo noo khaws cov khoom lag luam ntawm tus kheej thiab ua lub luag haujlwm tseem ceeb hauv kev tsim cov ntaub ntawv tshaj lij thiab kev siv biomedical.
