1. Usetyenziso:

I-1,2,4,5-cyclohexanetetracarboxylic dianhydride ifumana izicelo ezibanzi ekuveliseni iipolymers ezichasene nobushushu kunye ne-resins.Inika uzinzo oluhle kakhulu lwe-thermal, iqondo lobushushu obuphezulu beglasi, kunye neepropathi ezibalaseleyo zoomatshini, iyenza ibe lolona khetho lufanelekileyo kwiiplastiki zobunjineli, iingubo, izinto zokuncamathelisa, kunye ne-composites.Ukukwazi kwayo ukumelana neemeko ezigqithisileyo, ezinje ngamaqondo obushushu aphezulu kunye neekhemikhali ezinoburharha, iboleka kumashishini ahlukeneyo aquka iimoto, i-aerospace, i-electronics kunye nolwakhiwo.

2. Iinzuzo:

Ngenxa yobume bayo obukhethekileyo kunye neepropati, i-CHTCDA ibonelela ngeenzuzo ezininzi eziphawulekayo.Okokuqala, inika ukuxhathisa ubushushu obuphezulu kunye nokubuyiswa komlilo kwizinto eziphathekayo, ukwandisa ukhuseleko kunye nokuqina kweemveliso zokugqibela.Okwesibini, ukuzinza kwayo okukhethekileyo kwe-thermal kuqinisekisa ukuba iipolymers zokugqibela kunye ne-resin zihlala zingachatshazelwa bubushushu obugqithisileyo obufunyenwe ngexesha lokucubungula kunye nokusetyenziswa.Ngaphezu koko, le khemikhali ibonisa iimpawu ezigqwesileyo zokugquma umbane, ziyenza ilungele izinto zombane kunye nezombane.

3. Iinkcukacha:

I-1,2,4,5-cyclohexanetetracarboxylic dianhydride ifumaneka kwifomu yegranular, kunye nenqanaba lokucoceka kwe-99% okanye ngaphezulu.Inobunzima bemolekyuli ye-218.13 g/mol kunye nendawo yokunyibilika malunga ne-315.°C. Le khemikhali izinzile phantsi kweemeko eziqhelekileyo zokugcina kwaye kufuneka igcinwe kwindawo epholileyo, eyomileyo ukuze igcine ingqibelelo yayo.

Ukuqukumbela, i-1,2,4,5-cyclohexanetetracarboxylic dianhydride yi-compound yekhemikhali esebenzayo kunye nexabiso elixabisekileyo elisetyenziswa ngokubanzi kwimveliso yeepolymers eziphezulu kunye ne-resin.Iimpawu zayo ezibalaseleyo, kubandakanya ukumelana nobushushu, ukuzinza kwe-thermal, kunye nokufakelwa kombane, kuyenza ibe sisithako esiyimfuneko kumashishini ahlukeneyo.Siyakuqinisekisa ngowona mgangatho uphezulu, ukucoceka, kunye nokuthembeka kuyo yonke ibhetshi yeCHTCDA oyifumana kuthi.
