Bis (2,6-diisopropylphenyl) carbodiimideCAS 2162-74-5yog monomeric carbodiimide, ib tug sawv cev ntawm ntau yam anti-hydrolysis tus neeg sawv cev uas muaj cov yam ntxwv ntawm siab purity, lub teeb xim, tsis muaj ntxhiab thiab siab activity. Bis (2,6-diisopropylphenyl) carbodiimide yog dav siv nyob rau hauv cov ntaub ntawv xws li polyester polyol, nylon, engineering plastics muaj ester pawg, polyurethane elastomers, adhesives, txheej systems, thiab lubricating roj. Bis (2,6-diisopropylphenyl) carbodiimide tuaj yeem zoo inhibited lub hydrolysis ntawm cov ntaub ntawv zoo li no thiab stabilize cov khoom siv kho tshuab pib. Tib lub sijhawm,bis(2,6-diisopropylphenyl) carbodiimide kuj tseem tuaj yeem thaiv cov carboxyl terminations ntawm cov ntaub ntawv polyester. Kho cov ntaub ntawv polyester thiab polyurethane uas puas lawm,byog (2,6-diisopropylphenyl) carbodiimide tuaj yeem ua kom lub neej ua haujlwm ntev dua ntawm cov khoom polymer nyob rau hauv cov xwm txheej ua haujlwm hnyav xws li kub thiab av noo..

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

Ua ntej tshaj,bis (2,6-diisopropylphenyl) carbodiimide yog siv dav hauv polyurethane elastomers (xws li TPU, CPU), adhesives, sole solutions thiab Microporous elastomers, thiab lwm yam. Hauv cov teb no, los ntawm kev ntxiv 0.3-2.0% bis (2,6-diisopropylphenyl) carbodiimide, lub neej ua haujlwm ntawm cov khoom tuaj yeem txhim kho tau zoo heev, txuas ntxiv nws 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 qhov acid ntawm polyester. Kev txhim kho tseem ceeb hauv cov khoom zoo tuaj yeem ua tiav nrog cov nyiaj ntxiv qis dua, txuas ntxiv kev ruaj khov mus sij hawm ntev ntawm cov khoom.

Ntxiv rau kev siv ua tus neeg sawv cev tiv thaiv hydrolysis, bis (2,6-diisopropylphenyl) carbodiimide kuj tseem siv tau ua cov khoom pab ua kom cov tshuaj tiv thaiv nrog cov carboxylic acids tsim tawm thaum lub sijhawm extrusion. kev tiv thaiv, tiv thaiv kev txo qis ntawm qhov hnyav molecular, ua rau lub zog puas tsuaj rau cov polymer thaum lub sijhawm ua haujlwm, ua rau nws yooj yim dua rau kev khiav lag luam thiab txhim kho kev nyab xeeb ua piv rau lwm txoj hauv kev.

Ntxiv mus, rau cov yas PLA uas tsis muaj kuab lom uas tsis ua rau ib puag ncig puas tsuaj, kev tiv thaiv hydrolysis tsis zoo yeej ib txwm yog qhov teeb meem loj uas txwv tsis pub nws siv dav. PLA yooj yim puas tsuaj rau hauv cov chaw noo noo, cuam tshuam rau nws cov kev ua tau zoo thiab lub neej ntev. 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 dav duatcov teb daim ntawv thov ntawm PLA.

Hauv kev suav tag nrhomary, bis (2,6-diisopropylphenyl) carbodiimide, ua ib qho kev ua haujlwm siab tiv thaiv hydrolysis stabilizer, tau qhia txog kev siv dav dav thiab muaj peev xwm hauv kev tshawb fawb txog cov ntaub ntawv.ItVim muaj cov khoom siv zoo heev rau lub cev thiab tshuaj, ntau yam kev siv, thiab cov kev daws teeb meem rau cov ntaub ntawv tshwj xeeb (xws li PLA) ua rau bis(2,6-diisopropylphenyl)carbodiimide ua tus thawj coj hauv kev ruaj khov ntawm cov ntaub ntawv. Nrog rau kev nce qib ntawm kev tshawb fawb txog cov ntaub ntawv thiab kev paub txog kev tiv thaiv ib puag ncig, bis(2,6-diisopropylphenyl)carbodiimide thiab nws cov khoom zoo sib xws yuav raug txhawb nqa thiab siv rau ntau qhov chaw.
