I-Bis(2,6-diisopropylphenyl) carbodiimideI-CAS 2162-74-5yi-monomeric carbodiimide, uhlobo olumele i-anti-hydrolysis agent eneempawu zobumsulwa obuphezulu, umbala okhanyayo, akukho vumba kunye nomsebenzi ophezulu. I-Bis(2,6-diisopropylphenyl) carbodiimide isetyenziswa kakhulu kwizinto ezifana ne-polyester polyol, i-nylon, iiplastiki zobunjineli eziqulethe iqela le-ester, ii-polyurethane elastomers, izincamathelisi, iinkqubo zokugquma, kunye neoyile yokuthambisa. I-Bis(2,6-diisopropylphenyl) carbodiimide inokuthintela ngempumelelo i-hydrolysis yezinto ezinjalo kwaye izinzise iimpawu zokuqala zoomatshini. Kwangaxeshanye,bi-carbodiimide eyi-(2,6-diisopropylphenyl) inokuthintela ukuphela kwe-carboxyl esebenzayo kwizinto ze-polyester. Lungisa izinto ze-polyester ezonakeleyo kunye ne-polyurethane,bi-carbodiimide eyi-(2,6-diisopropylphenyl) inokwandisa ubomi benkonzo yeemveliso ze-polymer phantsi kweemeko zokusebenza ezinzima ezifana nobushushu obuphezulu kunye nokufuma.

Kwicandelo lesayensi yezinto eziphathekayo, i-bis(2,6-diisopropylphenyl)carbodiimide, njenge-monomeric carbodiimide anti-hydrolysis stabilizer, iye yaba yindawo ephambili kushishino ngenxa yokusebenza kwayo okugqwesileyo kunye namathuba okusetyenziswa ngokubanzi.

Okokuqala,i-bis(2,6-diisopropylphenyl) carbodiimide isetyenziswa kakhulu kwi-polyurethane elastomers (ezifana ne-TPU, i-CPU), izincamathelisi, izisombululo ze-sole kunye ne-Microporous elastomers, njl.njl. Kule mimandla, ngokongeza i-0.3-2.0% bis(2,6-diisopropylphenyl)carbodiimide., Ubomi benkonzo yemveliso bunokuphuculwa kakhulu, buyandise ukuya kuthi ga kwi-1 ukuya kwi-3.

Okwesibini, ngexesha lenkqubo yokuguqula izinto zepolyester ezifana nePET/PBT, ukongeza i-bis(2,6-diisopropylphenyl) carbodiimide kunokunciphisa ixabiso le-asidi yepolyester. Uphuculo olukhulu kumgangatho wezinto lunokufezekiswa ngokongeza okuncinci, okwandisa uzinzo lwexesha elide lwezinto.

Ukongeza ekusetyenzisweni njenge-arhente yokulwa ne-hydrolysis, i-bis(2,6-diisopropylphenyl)carbodiimide ingasetyenziselwa noncedo lokucubungula ukusabela kunye nee-carboxylic acids eziveliswa ngexesha lenkqubo yokukhupha i-extrusion, ukuthintela ukunciphisa ubunzima beemolekyuli, ukwenza buthathaka umonakalo kwi-polymer ngexesha lokucubungula, okwenza kube lula ukuyisebenzisa kunye nokuphucula ukhuseleko lokucubungula xa kuthelekiswa nezinye iindlela.

Ukongeza, kwi-PLA yeplastiki enobuhlobo nokusingqongileyo ebolayo, ukumelana ne-hydrolysis embi bekusoloko kuyingxaki enkulu ethintela ukusetyenziswa kwayo ngokubanzi. I-PLA yonakala lula kwiindawo ezifumileyo, nto leyo echaphazela ukusebenza kwayo kunye nobomi bayo. Nangona kunjalo, ngokongeza i-0.3-0.5% bis(2,6-diisopropylphenyl)carbodiimide kwi-PLA, ukumelana kwayo namanzi kunokuphuculwa kakhulu ngamaxesha ama-3-7, nto leyo eyandisa ngempumelelo i-tamasimi okusetyenziswa kwePLA.

Isimbukumi-bis(2,6-diisopropylphenyl)carbodiimide, njengesiqinisi sokulwa ne-hydrolysis esisebenza kakuhle, ibonakalise amandla okusetyenziswa ngokubanzi kunye namandla kwicandelo lesayensi yezinto.ItIipropati zayo zomzimba nezekhemikhali ezibalaseleyo, uluhlu olubanzi lwezicelo, kunye nezisombululo ezijolise kwizixhobo ezithile (ezifana ne-PLA) zenza i-bis(2,6-diisopropylphenyl)carbodiimide ibe yinkokeli ekuzinziseni izixhobo. Ngokuqhubeka kwenzululwazi yezinto kunye nokwanda kolwazi ngokhuseleko lokusingqongileyo, i-bis(2,6-diisopropylphenyl)carbodiimide kunye neemveliso zayo ezifanayo kulindeleke ukuba zikhuthazwe kwaye zisetyenziswe kwiindawo ezininzi.
