Bis(2,6-disopropylphenyl) carbodiimideCAS 2162-74-5is monomeric carbodiimide, mumiririri akasiyana-siyana e-anti-hydrolysis agent ane maitiro ekuchena kwepamusoro, ruvara rwechiedza, pasina kunhuhwirira uye basa rakakwirira. Bis(2,6-disopropylphenyl) carbodiimide inoshandiswa zvakanyanya muzvinhu zvakaita sepolyester polyol, naironi, mapurasitiki einjiniya ane ester boka, polyurethane elastomers, adhesives, coating system, uye mafuta ekuzora. Bis(2,6-disopropylphenyl) carbodiimide inogona kunyatso kuvharidzira hydrolysis yezvinhu zvakadaro uye kudzikamisa yekutanga michina zvinhu. Panguva imwe,bis(2,6-disopropylphenyl) carbodiimide inogonawo kuvhara iyo inoshanda carboxyl kuguma kwezvinhu zvepolyester. Gadzirisa yakakuvadzwa polyester uye polyurethane zvinhu,bis(2,6-disopropylphenyl) carbodiimide inogona kurebesa hupenyu hwesevhisi yezvigadzirwa zvepolymer pasi pemamiriro ekushanda akaomarara senge tembiricha yepamusoro uye hunyoro..
Mumunda wezvekushandisa sainzi, bis(2,6-disopropylphenyl)carbodiimide, se monomeric carbodiimide anti-hydrolysis stabilizer, yave kutarisa kweindastiri nekuda kwekuita kwayo kwakanaka uye tarisiro yekushandiswa kwakafara.
Chekutanga,bis(2,6-disopropylphenyl) carbodiimide inoshandiswa zvakanyanya mu polyurethane elastomers (senge TPU, CPU), zvinonamira, mhinduro chete uye Microporous elastomers, nezvimwewo. Muminda iyi, nekuwedzera 0.3-2.0% bis(2,6-disopropylphenyl)carbodiimide., hupenyu hwebasa hwechigadzirwa hunogona kuvandudzwa zvakanyanya, huchiwedzera kusvika ku1 kusvika ku3 nguva.
Chechipiri, panguva yekugadziriswa kwezvinhu zvepolyester sePET / PBT, kuwedzera bis (2,6-disopropylphenyl) carbodiimide inogona kuderedza kukosha kweasidhi yepolyester. Kuvandudzwa kwakakosha mumhando yezvinhu kunogona kuwanikwa neakaderera kuwedzera huwandu, kuwedzera kugadzikana kwenguva refu kwezvinhu.
Pamusoro pekushandiswa seanorwisa-hydrolysis agent, bis (2,6-disopropylphenyl) carbodiimide inogonawo kushandiswa seyamuro yekugadzirisa kugadzirisa ne carboxylic acids inogadzirwa panguva ye extrusion process. kuita, kudzivirira kudzikiswa kwehuremu hwemamorekuru, kuderedza kukuvadzwa kwepolymer panguva yekugadziriswa, zvichiita kuti zvive nyore kushanda nekuvandudza kuchengetedza kwekuchengetedza zvichienzaniswa nedzimwe nzira.
Pamusoro pezvo, kune biodegradable yezvakatipoteredza ine hushamwari epurasitiki PLA, kushomeka kwehydrolysis kuramba kwagara kuri bhodhoro guru rinorambidza kushandiswa kwayo kwakakura. PLA inoderedzwa nyore nyore munzvimbo dzine hunyoro, inokanganisa kuita kwayo uye hupenyu hwehupenyu. Nekudaro, nekuwedzera 0.3-0.5% bis (2,6-disopropylphenyl) carbodiimide kuPLA, kudzivirira kwayo kwemvura kunogona kuvandudzwa zvakanyanya ne3-7 nguva, zvichiwedzera kuwedzeratiye minda yekushandisa yePLA.
Muchidimbumary, bis(2,6-disopropylphenyl)carbodiimide, seyepamusoro-inoshanda anti-hydrolysis stabilizer, yakaratidza yakafara application kugona uye kugona mumunda wezvinhu zvesainzi. value.Its yakanakisa yemuviri uye makemikari zvimiro, zvakasiyana-siyana zvekushandisa, uye zvakanangwa zvigadziriso zvezvakati zvinhu (senge PLA) inoita bis(2,6-disopropylphenyl)carbodiimide mutungamiri mukudzikamisa zvinhu. Nekuenderera mberi kwekufambira mberi kwesainzi yemidziyo uye kuwedzera kuziva kwekuchengetedzwa kwezvakatipoteredza, bis(2,6-disopropylphenyl)carbodiimide uye zvigadzirwa zvayo zvakafanana zvinotarisirwa kusimudzirwa uye kushandiswa mune mamwe minda.
