Bis(2,6-disopropylphenyl) carbodiimideI-CAS 2162-74-5i-monomeric carbodiimide, ummeli ohlukeneyo we-anti-hydrolysis agent eneempawu zokucoceka okuphezulu, umbala okhanyayo, akukho vumba kunye nomsebenzi ophezulu. I-Bis(2,6-disopropylphenyl) i-carbodiimide isetyenziswa kakhulu kwizinto ezifana ne-polyester polyol, nayiloni, iiplastiki zobunjineli ezineqela le-ester, i-polyurethane elastomers, izinto zokuncamathelisa, iinkqubo zokugquma, kunye ne-oyile yokuthambisa. I-Bis (2,6-disopropylphenyl) i-carbodiimide inokuthintela ngokufanelekileyo i-hydrolysis yezinto ezinjalo kunye nokuzinzisa iimpawu zokuqala zomatshini. Ngaxeshanye,byi(2,6-disopropylphenyl) i-carbodiimide inokubhloka kwakhona ukupheliswa kwe-carboxyl esebenzayo yezinto zepolyester. Lungisa izinto ezonakalisiweyo zepolyester kunye ne-polyurethane,byi(2,6-disopropylphenyl) carbodiimide inokwandisa ubomi benkonzo yeemveliso zepolymer phantsi kweemeko zokusebenza ezinzima ezifana nobushushu obuphezulu kunye nokufuma..

Kwinkalo yezinto zenzululwazi, i-bis(2,6-disopropylphenyl)carbodiimide, njenge-monomeric carbodiimide anti-hydrolysis stabilizer, iye yaba yingqwalasela yoshishino ngokusebenza kwayo okugqwesileyo kunye nethemba elibanzi lesicelo.

Okokuqala,i-bis(2,6-disopropylphenyl) i-carbodiimide isetyenziswa kakhulu kwi-polyurethane elastomers (efana ne-TPU, i-CPU), i-adhesives, izisombululo zodwa kunye ne-Microporous elastomers, njl. Kule mihlaba, ngokongeza i-0.3-2.0% bis(2,6-disopropylphenyl)carbodiimide, ubomi benkonzo yemveliso bunokuphuculwa kakhulu, ukwandisa ukuya kuthi ga kwi-1 ukuya kwi-3 amaxesha.

Okwesibini, ngexesha lenkqubo yokuguqulwa kwezinto ze-polyester ezifana ne-PET / PBT, ukongeza i-bis (2,6-disopropylphenyl) i-carbodiimide inokunciphisa ixabiso le-asidi ye-polyester. Ukuphuculwa okuphawulekayo kumgangatho wezinto eziphathekayo kunokufezekiswa ngezixa ezisezantsi zokongeza, ukwandisa ukuzinza kwexesha elide lezinto eziphathekayo.

Ngaphandle kokusetyenziswa njenge-anti-hydrolysis agent, i-bis (2,6-disopropylphenyl) carbodiimide ingasetyenziselwa njengento yokuncedisa ukusabela nge-carboxylic acids eveliswa ngexesha lenkqubo ye-extrusion. ukusabela, ukuthintela ukucutha ubunzima molekyuli, buthathaka umonakalo kwipolymer ngexesha processing, ukwenza kube lula ukusebenza kunye nokuphucula processing ukhuseleko xa kuthelekiswa nezinye iindlela.

Ukongeza, kwi-PLA ye-biodegradable ye-biodegradable ye-PLAstiki ehambelana nokusingqongileyo, ukunganyangeki kwe-hydrolysis isoloko ingumqobo omkhulu othintela ukusetyenziswa kwayo ngokubanzi. I-PLA ithotywa ngokulula kwiindawo ezifumileyo, ezichaphazela ukusebenza kwayo kunye nobomi bayo. Nangona kunjalo, ngokongeza i-0.3-0.5% bis (2,6-disopropylphenyl) carbodiimide kwi-PLA, ukuxhathisa kwayo kwamanzi kunokuphuculwa kakhulu ngamaxesha angama-3-7, ngokufanelekileyo ukwandisatiindawo zesicelo zePLA.

Ngesishwankathelomary, bis (2,6-disopropylphenyl) carbodiimide, njenge-high-performance anti-hydrolysis stabilizer, ibonise usetyenziso olubanzi kunye namandla kwintsimi yezinto zesayensi. ixabiso.Its iimpawu ezibalaseleyo zomzimba kunye neekhemikhali, uluhlu olubanzi lwezicelo, kunye nezisombululo ezijoliswe kuzo kwizinto ezithile (ezifana ne-PLA) zenza i-bis (2,6-disopropylphenyl) i-carbodiimide inkokeli ekuzinziseni izinto. Ngokuqhubela phambili okuqhubekayo kwesayensi yezinto kunye nokwanda kolwazi lokukhuselwa kwendalo, i-bis(2,6-disopropylphenyl)carbodiimide kunye neemveliso zayo ezifanayo kulindeleke ukuba zikhuthazwe kwaye zisetyenziswe kwiinkalo ezininzi.
