Bis(2,6-diisopropylphenyl) carbodiimideCAS 2162-74-5imonomeric carbodiimide, mhando inomiririra yemushonga unodzivirira hydrolysis une hunhu hwekuchena kwakanyanya, ruvara rwakajeka, husina hwema uye kushanda kwakanyanya. Bis(2,6-diisopropylphenyl) carbodiimide inoshandiswa zvakanyanya muzvinhu zvakaita sepolyester polyol, nylon, mapurasitiki einjiniya ane ester group, polyurethane elastomers, adhesives, coating systems, uye lubricating oil. Bis(2,6-diisopropylphenyl) carbodiimide inogona kudzivirira hydrolysis yezvinhu zvakadaro uye kudzikamisa hunhu hwekutanga hwemakanika. Panguva imwe chete,bis(2,6-diisopropylphenyl) carbodiimide inogonawo kuvharira kupera kwecarboxyl yezvinhu zvepolyester. Gadzirisa zvinhu zvepolyester nepolyurethane zvakakuvara,bis(2,6-diisopropylphenyl) carbodiimide inogona kuwedzera hupenyu hwebasa rezvigadzirwa zvepolymer mumamiriro ekushanda akaoma akadai sekupisa kwakanyanya uye hunyoro..

Mumunda wesainzi yezvinhu, bis(2,6-diisopropylphenyl)carbodiimide, se monomeric carbodiimide anti-hydrolysis stabilizer, yave chinhu chinonyanya kukosheswa neindasitiri iyi nekuda kwekushanda kwayo kwakanaka uye mikana yakawanda yekushandiswa kwayo.

Chekutanga,bis(2,6-diisopropylphenyl) carbodiimide inoshandiswa zvakanyanya mu polyurethane elastomers (dzakadai seTPU, CPU), adhesives, sole solutions uye Microporous elastomers, nezvimwewo. Muminda iyi, nekuwedzera 0.3-2.0% bis(2,6-diisopropylphenyl)carbodiimide., Hupenyu hwebasa rechigadzirwa hunogona kuvandudzwa zvakanyanya, huchiwedzera kusvika ka1 kusvika katatu.

Chechipiri, panguva yekugadzirisa zvinhu zvepolyester zvakaita sePET/PBT, kuwedzera bis(2,6-diisopropylphenyl) carbodiimide kunogona kuderedza acid yepolyester. Kuvandudzwa kukuru mumhando yezvinhu kunogona kuwanikwa nehuwandu hwakaderera hwekuwedzera, zvichiwedzera kugadzikana kwenguva refu kwezvinhu.

Pamusoro pekushandiswa semushonga unodzivirira hydrolysis, bis(2,6-diisopropylphenyl)carbodiimide inogonawo kushandiswa semubatsiri wekugadzirisa kuti iite zvinoenderana necarboxylic acids inogadzirwa panguva yekubvisa makemikari, ichidzivirira kudzikira kwehuremu hwemamorekuru, ichideredza kukuvara kwepolymer panguva yekugadzirisa, zvichiita kuti zvive nyore kushanda uye inovandudza kuchengetedzeka kwekugadzirisa zvichienzaniswa nedzimwe nzira.

Pamusoro pezvo, kune PLA yepurasitiki isingaori, isingakuvadzi nharaunda, kuramba kuripo kwehydrolysis kwagara kuri dambudziko guru rinotadzisa kushandiswa kwayo zvakanyanya. PLA inogona kuora nyore nyore munzvimbo dzine hunyoro, zvichikanganisa mashandiro ayo uye hupenyu hwayo. Zvisinei, nekuwedzera 0.3-0.5% bis(2,6-diisopropylphenyl)carbodiimide kuPLA, kuramba kwayo mvura kunogona kuvandudzwa zvakanyanya ka3-7, zvichibatsira kuwedzera huwandu hwemvura.tminda yekushandisa yePLA.

Muchidimbumary, bis(2,6-diisopropylphenyl)carbodiimide, semushonga unosimbisa hydrolysis unoshanda zvakanyanya, waratidza kugona kwakakura kwekushandisa uye kugona mumunda wesainzi yezvinhu. kukosha.ItHunhu hwayo hwakanaka hwemuviri nemakemikari, mashandisirwo akasiyana-siyana, uye mhinduro dzakanangana nezvinhu zvakati (senge PLA) zvinoita kuti bis(2,6-diisopropylphenyl)carbodiimide ive mutungamiri mukugadzikana kwezvinhu. Nekufambira mberi kuri kuramba kuchiita sainzi yezvinhu uye kuwedzera kweruzivo rwekuchengetedzwa kwezvakatipoteredza, bis(2,6-diisopropylphenyl)carbodiimide nezvimwe zvigadzirwa zvayo zvakafanana zvinotarisirwa kusimudzirwa nekushandiswa mune dzimwe nzvimbo.
