I-Bis(2,6-diisopropylphenyl) carbodiimideI-CAS 2162-74-5yi-monomeric carbodiimide, uhlobo olumele lwe-anti-hydrolysis agent enezici zobumsulwa obuphezulu, umbala okhanyayo, ukungabi nephunga kanye nomsebenzi ophezulu. I-Bis(2,6-diisopropylphenyl) carbodiimide isetshenziswa kabanzi ezintweni ezifana ne-polyester polyol, i-nylon, amapulasitiki obunjiniyela aqukethe iqembu le-ester, ama-polyurethane elastomers, izinamathiselo, izinhlelo zokumboza, kanye namafutha okugcoba. I-Bis(2,6-diisopropylphenyl) carbodiimide ingavimbela ngempumelelo i-hydrolysis yezinto ezinjalo futhi izinzise izakhiwo zokuqala zemishini. Ngesikhathi esifanayo,bi-carbodiimide eyi-(2,6-diisopropylphenyl) ingavimba nokuphela kwe-carboxyl esebenzayo kwezinto ze-polyester. Lungisa izinto ze-polyester ne-polyurethane ezonakele,bi-carbodiimide (2,6-diisopropylphenyl) ingandisa isikhathi sokuphila kwemikhiqizo ye-polymer ngaphansi kwezimo zokusebenza ezinzima njengokushisa okuphezulu kanye nomswakama.

Emkhakheni wesayensi yezinto zokwakha, i-bis(2,6-diisopropylphenyl)carbodiimide, njenge-monomeric carbodiimide anti-hydrolysis stabilizer, isibe yindawo ebalulekile embonini ngenxa yokusebenza kwayo okuhle kakhulu kanye namathuba okusetshenziswa okubanzi.

Okokuqala,I-bis(2,6-diisopropylphenyl) carbodiimide isetshenziswa kabanzi kuma-polyurethane elastomers (njenge-TPU, i-CPU), izinamathiseli, izixazululo ze-sole kanye nama-Microporous elastomers, njll. Kulezi zinkambu, ngokungeza i-0.3-2.0% bis(2,6-diisopropylphenyl)carbodiimide, impilo yesevisi yomkhiqizo ingathuthukiswa kakhulu, inwetshwe kuze kube izikhathi ezi-1 kuya kwezi-3.

Okwesibili, ngesikhathi senqubo yokuguqulwa kwezinto ze-polyester ezifana ne-PET/PBT, ukwengeza i-bis(2,6-diisopropylphenyl) carbodiimide kunganciphisa inani le-asidi le-polyester. Ukuthuthuka okukhulu kwekhwalithi yezinto kungatholakala ngamanani aphansi okwengeza, okwandisa ukuzinza kwesikhathi eside kwezinto.

Ngaphezu kokusetshenziswa njenge-anti-hydrolysis agent, i-bis(2,6-diisopropylphenyl)carbodiimide ingasetshenziswa futhi njengosizo lokucubungula ukuze isabelane nama-carboxylic acid akhiqizwa ngesikhathi senqubo yokukhipha. ukusabela, ukuvimbela ukwehla kwesisindo sama-molecule, ukwenza buthaka umonakalo ku-polymer ngesikhathi sokucubungula, okwenza kube lula ukusebenza futhi kuthuthukiswe ukuphepha kokucubungula uma kuqhathaniswa nezinye izindlela.

Ngaphezu kwalokho, kwi-PLA yepulasitiki enobungani nemvelo ebolayo, ukumelana okungekuhle kwe-hydrolysis bekulokhu kuyisithiyo esikhulu esivimbela ukusetshenziswa kwayo kabanzi. I-PLA yonakala kalula ezindaweni ezinomswakama, okuthinta ukusebenza kwayo kanye nesikhathi sayo sokuphila. Kodwa-ke, ngokungeza i-0.3-0.5% bis(2,6-diisopropylphenyl)carbodiimide ku-PLA, ukumelana kwayo namanzi kungathuthukiswa kakhulu izikhathi ezingu-3-7, okwandisa ngempumelelo i-tamasimu ohlelo lokusebenza lwe-PLA.

Sekukonkemi-ary, i-bis(2,6-diisopropylphenyl)carbodiimide, njengesiqinisi sokulwa ne-hydrolysis esisebenza kahle kakhulu, ibonise amandla okusetshenziswa abanzi kanye namandla emkhakheni wesayensi yezinto zokwakha. inani.ItIzakhiwo zayo ezinhle kakhulu zomzimba nezamakhemikhali, ububanzi bezicelo, kanye nezixazululo eziqondiwe zezinto ezithile (njenge-PLA) kwenza i-bis(2,6-diisopropylphenyl)carbodiimide ibe ngumholi ekuzinziseni izinto. Ngokuthuthuka okuqhubekayo kwesayensi yezinto kanye nokuqwashisa okwandayo ngokuvikelwa kwemvelo, i-bis(2,6-diisopropylphenyl)carbodiimide kanye nemikhiqizo yayo efanayo kulindeleke ukuthi ikhuthazwe futhi isetshenziswe emikhakheni eminingi.
