Bis (2,6-diisopropylphenyl) karbodiimideCAS 2162-74-5ni monomeric carbodiimide, ubwoko butandukanye bwo kurwanya anti-hydrolysis ifite ibiranga isuku ryinshi, ibara ryoroheje, nta mpumuro nibikorwa byinshi. Bis (2,6-diisopropylphenyl) karbodiimide ikoreshwa cyane mubikoresho nka polyester polyol, nylon, plastiki yubuhanga irimo itsinda rya ester, polyurethane elastomers, ibifatika, sisitemu yo gutwikira, hamwe namavuta yo gusiga. Bis (2,6-diisopropylphenyl) karbodiimide irashobora guhagarika neza hydrolysis yibyo bikoresho kandi igahindura imiterere yambere yubukanishi. Muri icyo gihe,bni (2,6-diisopropylphenyl) karbodiimide irashobora kandi guhagarika carboxyl ikora yibikoresho bya polyester. Gusana ibikoresho bya polyester byangiritse nibikoresho bya polyurethane,bni (2,6-diisopropylphenyl) karbodiimide irashobora kongera igihe cyumurimo wibicuruzwa bya polymer mubihe bigoye byakazi nkubushyuhe bwinshi nubushuhe.

Mu rwego rwibikoresho siyanse, bis (2,6-diisopropylphenyl) karbodiimide, nka monomeric carbodiimide anti-hydrolysis stabilisateur, yabaye intandaro yinganda kubikorwa byayo byiza kandi byifuzo byinshi.

Ubwa mbere,bis (2,6-diisopropylphenyl) karbodiimide ikoreshwa cyane muri elastomers ya polyurethane (nka TPU, CPU), ibifatika, ibisubizo byonyine hamwe na elastomers ya Microporome, nibindi. Muri iyi mirima, wongeyeho 0.3-2.0% bis (2,6-diisopropylphenyl) karbodiimide, ubuzima bwa serivisi bwibicuruzwa burashobora kunozwa cyane, bikagurwa inshuro 1 kugeza kuri 3.

Icya kabiri, mugihe cyo guhindura ibikoresho bya polyester nka PET / PBT, wongeyeho bis (2,6-diisopropylphenyl) karbodiimide irashobora kugabanya agaciro ka aside ya polyester. Iterambere rikomeye mubyiza byibintu birashobora kugerwaho hamwe ninyongera yinyongera, bikongerera igihe kirekire ibintu bifatika.

Usibye gukoreshwa nka anti-hydrolysis, bis (2,6-diisopropylphenyl) karbodiimide irashobora kandi gukoreshwa nkimfashanyo yo gutunganya kugirango ikore hamwe na acide karubike yakozwe mugihe cyo gukuramo. reaction, kubuza kugabanya uburemere bwa molekile, kugabanya ibyangiritse kuri polymer mugihe cyo gutunganya, byoroshye gukora no kunoza umutekano wo gutunganya ugereranije nubundi buryo.

Byongeye kandi, kubinyabuzima byangiza ibidukikije byangiza ibidukikije PLA, kutarwanya hydrolysis byahoze ari inzitizi ikomeye igabanya ikoreshwa ryayo. PLA yangiritse byoroshye mubidukikije, bigira ingaruka kumikorere no mubuzima bwe. Nyamara, wongeyeho 0.3-0.5% bis (2,6-diisopropylphenyl) karbodiimide muri PLA, kurwanya amazi kwayo birashobora kunozwa cyane inshuro 3-7, bikaguka nezatasaba imirima ya PLA.

Muri rusangemary, bis (2,6-diisopropylphenyl) karbodiimide, nka stabilisateur-anti-hydrolysis ikora cyane, yerekanye ubushobozi bushoboka hamwe nubushobozi mubijyanye na siyansi yubumenyi. agaciro.Its ibintu byiza byumubiri nubumashini, ibintu byinshi, hamwe nibisubizo byibikoresho byihariye (nka PLA) bituma bis (2,6-diisopropylphenyl) karbodiimide iba umuyobozi muguhindura ibikoresho. Hamwe nogukomeza gutera imbere mubumenyi siyanse no kurushaho gukangurira kurengera ibidukikije, bis (2,6-diisopropylphenyl) karbodiimide nibicuruzwa bisa nayo biteganijwe ko bizamurwa kandi bigashyirwa mubikorwa byinshi.
