Bis (2,6-diisopropylphenyl) carbodiimideCAS 2162-74-5 Nryog monomeric carbodiimide, ib tug neeg sawv cev ntawm ntau yam anti-hydrolysis tus neeg sawv cev uas muaj cov yam ntxwv ntawm siab purity, lub teeb xim, tsis muaj tsw thiab siab ua hauj lwm. Bis (2,6-diisopropylphenyl) carbodiimide yog dav siv nyob rau hauv cov ntaub ntawv xws li polyester polyol, nylon, engineering plastics uas muaj ester pawg, polyurethane elastomers, nplaum, txheej txheej, thiab lubricating roj. Bis (2,6-diisopropylphenyl) carbodiimide tuaj yeem cuam tshuam cov hydrolysis ntawm cov ntaub ntawv zoo li no thiab ua kom ruaj khov ntawm cov khoom siv tshuab ua ntej. Tib lub sijhawm,byog (2,6-diisopropylphenyl) carbodiimide tuaj yeem thaiv cov active carboxyl terminations ntawm polyester cov ntaub ntawv. Kho cov khoom puas polyester thiab polyurethane,byog (2,6-diisopropylphenyl) carbodiimide tuaj yeem ua rau lub neej ntev kev pab cuam ntawm cov khoom polymer nyob rau hauv kev ua haujlwm hnyav xws li kub thiab av noo..

Hauv cov ntaub ntawv tshawb fawb, bis (2,6-diisopropylphenyl) carbodiimide, Raws li monomeric carbodiimide anti-hydrolysis stabilizer, tau dhau los ua qhov tseem ceeb ntawm kev lag luam rau nws cov kev ua tau zoo thiab kev siv dav dav.

Ua ntej,bis (2,6-diisopropylphenyl) carbodiimide yog dav siv nyob rau hauv polyurethane elastomers (xws li TPU, CPU), adhesives, ib qho kev daws teeb meem thiab Microporous elastomers, thiab lwm yam. Hauv cov teb no, los ntawm kev ntxiv 0.3-2.0% bis (2,6-diisopropylphenyl) carbodiimide, Kev pabcuam lub neej ntawm cov khoom tuaj yeem txhim kho tau zoo, txuas ntxiv mus txog 1 txog 3 zaug.

Qhov thib ob, thaum lub sijhawm hloov kho cov ntaub ntawv polyester xws li PET / PBT, ntxiv bis (2,6-diisopropylphenyl) carbodiimide tuaj yeem txo cov kua qaub ntawm polyester. Kev txhim kho tseem ceeb hauv cov khoom siv tau zoo tuaj yeem ua tiav nrog cov nqi qis dua, txuas ntxiv kev ruaj ntseg ntawm cov khoom siv mus ntev.

Ntxiv nrog rau kev siv los ua cov tshuaj tiv thaiv hydrolysis, bis (2,6-diisopropylphenyl) carbodiimide tuaj yeem siv los ua kev pabcuam ua haujlwm rau cov tshuaj carboxylic acids uas tsim thaum lub sijhawm extrusion. cov tshuaj tiv thaiv, tiv thaiv qhov txo qis ntawm qhov hnyav molecular, ua kom tsis muaj zog ntawm kev puas tsuaj rau cov polymer thaum lub sijhawm ua haujlwm, ua kom yooj yim rau kev khiav lag luam thiab txhim kho kev nyab xeeb kev ua haujlwm piv nrog lwm txoj kev.

Tsis tas li ntawd, rau biodegradable ib puag ncig tus phooj ywg yas PLA, tsis zoo hydrolysis tsis kam yeej ib txwm yog ib qho tseem ceeb ntawm kev txwv tsis pub nws daim ntawv thov dav. PLA yog yooj yim degraded nyob rau hauv ib puag ncig ntub, cuam tshuam nws cov kev ua tau zoo thiab lifespan. Txawm li cas los xij, los ntawm kev ntxiv 0.3-0.5% bis (2,6-diisopropylphenyl) carbodiimide rau PLA, nws cov dej tsis kam tuaj yeem txhim kho tau zoo los ntawm 3-7 zaug, ua kom muaj txiaj ntsig zoo.tnws daim ntawv thov teb ntawm PLA.

Nyob rau hauv tag nrhomary, bis (2,6-diisopropylphenyl) carbodiimide, raws li kev ua haujlwm siab los tiv thaiv hydrolysis stabilizer, tau qhia dav siv peev xwm thiab muaj peev xwm hauv kev tshawb fawb cov ntaub ntawv. tus nqi.Its zoo heev lub cev thiab tshuaj muaj zog, ntau yam kev siv, thiab lub hom phiaj kev daws teeb meem rau cov ntaub ntawv tshwj xeeb (xws li PLA) ua bis (2,6-diisopropylphenyl) carbodiimide ib tug thawj coj nyob rau hauv cov ntaub ntawv stabilization. Nrog rau kev nce qib ntawm cov ntaub ntawv tshawb fawb thiab kev paub txog kev tiv thaiv ib puag ncig, bis (2,6-diisopropylphenyl) carbodiimide thiab nws cov khoom zoo sib xws yuav tsum tau txhawb nqa thiab siv rau hauv ntau qhov chaw.
