Bis(2,6-diisopropylphenyl) carbodiimideCAS 2162-74-5ndi monomeric carbodiimide, mtundu woyimira wa anti-hydrolysis agent womwe uli ndi makhalidwe a kuyera kwambiri, mtundu wopepuka, wopanda fungo komanso ntchito yayikulu. Bis(2,6-diisopropylphenyl) carbodiimide imagwiritsidwa ntchito kwambiri pazinthu monga polyester polyol, nayiloni, mapulasitiki opanga omwe ali ndi gulu la ester, polyurethane elastomers, zomatira, makina okutira, ndi mafuta opaka. Bis(2,6-diisopropylphenyl) carbodiimide imatha kuletsa bwino hydrolysis ya zinthu zotere ndikukhazikitsa mphamvu zoyambirira zamakina. Nthawi yomweyo,bis(2,6-diisopropylphenyl) carbodiimide imathanso kuletsa kutha kwa carboxyl yogwira ntchito pazinthu za polyester. Konzani zinthu za polyester ndi polyurethane zomwe zawonongeka,bis(2,6-diisopropylphenyl) carbodiimide imatha kutalikitsa moyo wa zinthu zopangidwa ndi polima pansi pa mikhalidwe yovuta yogwira ntchito monga kutentha kwambiri ndi chinyezi..

Mu sayansi ya zinthu, bis(2,6-diisopropylphenyl)carbodiimide, monga monomeric carbodiimide anti-hydrolysis stabilizer, yakhala malo ofunikira kwambiri pamakampani chifukwa cha magwiridwe antchito ake abwino komanso mwayi wogwiritsidwa ntchito kwambiri.

Choyamba,bis(2,6-diisopropylphenyl) carbodiimide imagwiritsidwa ntchito kwambiri mu polyurethane elastomers (monga TPU, CPU), zomatira, sole solutions ndi Microporous elastomers, ndi zina zotero. M'magawo awa, powonjezera 0.3-2.0% bis(2,6-diisopropylphenyl)carbodiimide, Moyo wautumiki wa chinthucho ukhoza kusinthidwa kwambiri, ndikuchikulitsa mpaka nthawi imodzi mpaka zitatu..

Kachiwiri, panthawi yosintha zinthu za polyester monga PET/PBT, kuwonjezera bis(2,6-diisopropylphenyl) carbodiimide kungachepetse asidi wa polyester. Kusintha kwakukulu pa khalidwe la zinthu kumatha kuchitika ndi kuwonjezera pang'ono, zomwe zimapangitsa kuti zinthuzo zikhale zolimba kwa nthawi yayitali.

Kuwonjezera pa kugwiritsidwa ntchito ngati mankhwala oletsa hydrolysis, bis(2,6-diisopropylphenyl)carbodiimide ingagwiritsidwenso ntchito ngati chithandizo chothandizira pokonza zinthu ndi ma carboxylic acid omwe amapangidwa panthawi ya extrusion reaction, kuteteza kuchepa kwa kulemera kwa mamolekyulu, kufooketsa kuwonongeka kwa polima panthawi yokonza, kupangitsa kuti ikhale yosavuta kugwiritsa ntchito ndikukweza chitetezo cha pokonza zinthu poyerekeza ndi njira zina.

Kuphatikiza apo, pa PLA yapulasitiki yosawononga chilengedwe, kukana kwa hydrolysis kosakwanira kwakhala vuto lalikulu lomwe limalepheretsa kugwiritsidwa ntchito kwake konse. PLA imawonongeka mosavuta m'malo onyowa, zomwe zimakhudza magwiridwe antchito ake komanso moyo wake. Komabe, powonjezera 0.3-0.5% bis(2,6-diisopropylphenyl)carbodiimide ku PLA, kukana kwake madzi kumatha kukwera kwambiri nthawi 3-7, zomwe zimapangitsa kuti ikhale yolimba kwambiri.tminda yogwiritsira ntchito ya PLA.

Zonsemary, bis(2,6-diisopropylphenyl)carbodiimide, monga choletsa hydrolysis stabilizer chogwira ntchito bwino, chawonetsa kuthekera kwakukulu kogwiritsidwa ntchito komanso kuthekera kwakukulu m'munda wa sayansi ya zinthu.ItKapangidwe kake kabwino kwambiri ka thupi ndi mankhwala, mitundu yosiyanasiyana ya ntchito, ndi mayankho olunjika pazinthu zinazake (monga PLA) zimapangitsa bis(2,6-diisopropylphenyl)carbodiimide kukhala mtsogoleri pakukhazikika kwa zinthu. Ndi kupita patsogolo kosalekeza kwa sayansi ya zinthu komanso chidziwitso chowonjezeka cha kuteteza chilengedwe, bis(2,6-diisopropylphenyl)carbodiimide ndi zinthu zina zofanana zikuyembekezeka kukwezedwa ndikugwiritsidwa ntchito m'magawo ambiri.
