Bis(2,6-disopropylphenyl) carbodiimideChithunzi cha CAS 2162-74-5ndi monomeric carbodiimide , woimira mitundu yosiyanasiyana ya anti-hydrolysis wothandizira omwe ali ndi makhalidwe a chiyero chapamwamba, mtundu wowala, wopanda fungo komanso ntchito zambiri. Bis(2,6-disopropylphenyl) carbodiimide imagwiritsidwa ntchito kwambiri pazinthu monga poliyesitala polyol, nayiloni, mapulasitiki opangira ma ester gulu, polyurethane elastomers, zomatira, zomatira, ndi mafuta opaka mafuta. Bis(2,6-disopropylphenyl) carbodiimide imatha kuletsa bwino hydrolysis ya zinthu zotere ndikukhazikitsa zoyambira zamakina. Nthawi yomweyo,bis(2,6-disopropylphenyl) carbodiimide imathanso kuletsa kutha kwa carboxyl kwa zinthu za polyester. Konzani zida zowonongeka za polyester ndi polyurethane,bndi(2,6-disopropylphenyl) carbodiimide imatha kutalikitsa moyo wautumiki wa zinthu za polima pansi pamikhalidwe yovuta yogwirira ntchito monga kutentha kwambiri ndi chinyezi..

M'munda wa sayansi yazinthu, bis(2,6-disopropylphenyl)carbodiimide, monga monomeric carbodiimide anti-hydrolysis stabilizer, yakhala cholinga chamakampani chifukwa chakuchita bwino komanso chiyembekezo chogwiritsa ntchito.

Choyamba,bis(2,6-disopropylphenyl) carbodiimide imagwiritsidwa ntchito kwambiri mu polyurethane elastomers (monga TPU, CPU), zomatira, zothetsera zokha ndi Microporous elastomers, etc. M'magawo awa, powonjezera 0.3-2.0% bis(2,6-disopropylphenyl)carbodiimide, moyo wautumiki wa chinthucho ukhoza kusintha kwambiri, kukulitsa mpaka 1 mpaka 3 nthawi.

Kachiwiri, panthawi yosintha zinthu za polyester monga PET/PBT, kuwonjezera bis(2,6-disopropylphenyl) carbodiimide kungachepetse mtengo wa asidi wa polyester. Kuwongolera kwakukulu kwazinthu zakuthupi kungathe kupezedwa ndi ndalama zochepa zowonjezera, kukulitsa kukhazikika kwa nthawi yaitali kwa zinthuzo.

Kuphatikiza pa kugwiritsidwa ntchito ngati anti-hydrolysis agent, bis (2,6-disopropylphenyl) carbodiimide ingagwiritsidwenso ntchito ngati chithandizo chothandizira kuchitapo kanthu ndi carboxylic acids opangidwa panthawi ya extrusion. zochita, kupewa kuchepetsa kulemera kwa maselo, kufooketsa kuwonongeka kwa polima panthawi yokonza, kukhala kosavuta kugwira ntchito ndi kuwongolera chitetezo cha processing poyerekeza ndi njira zina.

Kuphatikiza apo, kwa PLA ya pulasitiki yowononga zachilengedwe, kukana kwa hydrolysis kwakhala vuto lalikulu lomwe limaletsa kugwiritsa ntchito kwake konse. PLA imawonongeka mosavuta m'malo achinyezi, zomwe zimakhudza magwiridwe ake komanso moyo wake. Komabe, powonjezera 0.3-0.5% bis (2,6-disopropylphenyl) carbodiimide ku PLA, kukana kwake kwamadzi kumatha kupitsidwanso kwambiri ndi nthawi 3-7, kukulitsa bwinotadagwiritsa ntchito magawo a PLA.

Mwachidulemary, bis(2,6-disopropylphenyl)carbodiimide, monga anti-hydrolysis stabilizer yogwira ntchito kwambiri, yawonetsa kuthekera kwakukulu kogwiritsa ntchito komanso kuthekera pazasayansi yazinthu. mtengo.ItMawonekedwe abwino kwambiri akuthupi ndi mankhwala, ntchito zosiyanasiyana, ndi mayankho omwe amayang'aniridwa pazinthu zinazake (monga PLA) amapanga bis(2,6-disopropylphenyl)carbodiimide kukhala mtsogoleri pakukhazikika kwazinthu. Ndi kupita patsogolo kosalekeza kwa sayansi ya zida komanso kuzindikira kowonjezereka kwa chitetezo cha chilengedwe, bis(2,6-disopropylphenyl)carbodiimide ndi zinthu zake zofananira zikuyembekezeredwa kulimbikitsidwa ndikugwiritsidwa ntchito m'magawo ambiri.
