Iinkcukacha zeMveliso

Iithegi zeMveliso

- IiPropati zeMzimba kunye neMichiza: i-NTA inobunzima bemolekyuli ye-244.16 g / mol kunye nendawo yokunyibilika ye-352-358°C. Ibonisa ukunyibilika okugqwesileyo kwizinyibilikisi eziphilayo ezifana nekloroform, i-ethyl acetate, kunye nebenzene.Ukongezelela, ibonisa ukuzinza okulungileyo phantsi kweemeko eziqhelekileyo, okuvumela ukugcinwa kunye nokuthutha ngaphandle kokuthotywa okukhulu.

- Izicelo: I-NTA ifumana ukusetyenziswa kuluhlu olubanzi lwamashishini, kubandakanywa amayeza, iidayi, kunye neeplastiki.Kwicandelo loxubo mayeza, lisebenza njengombindi obalulekileyo ekudityanisweni kwamachiza, linegalelo kuphuhliso lonyango oluqalayo.Ukusebenza kwayo okuphezulu kunye nokuhambelana kwenza kube yinto efanelekileyo kwimveliso yeedayi eziphezulu zokusebenza, ukuhambisa iimpawu ezikhethekileyo zombala.Ngapha koko, i-NTA isetyenziswa njenge-monomer ekudityanisweni kweepholima ezikhethekileyo kunye nee-resin, ephucula ukusebenza kwazo zonke kunye nokuqina.

- Iingqwalasela zoKhuseleko: Xa uphethe i-1,4,5,8-naphthalene tetracarboxylic anhydride, kuyimfuneko ukugcina amanyathelo okhuseleko asemgangathweni.Le khompawundi kufuneka igcinwe kwindawo epholileyo, eyomileyo, kude namadangatye avulekileyo okanye imithombo yokutshisa.Ukungena komoya okufanelekileyo kubalulekile ngexesha lokusetyenziswa ukuthintela ukuphefumla nawuphi na umphunga onokubakho.Njengayo nayiphi na imichiza, kubalulekile ukunxiba izixhobo ezifanelekileyo zokuzikhusela, kubandakanya iiglavu kunye neglavu, ukunciphisa ukunxibelelana ngokuthe ngqo kunye nokuqinisekisa ukhuseleko lomntu.

Ukuqukumbela, i-1,4,5,8-naphthalene tetracarboxylic anhydride iyinto exabisekileyo yeekhemikhali esebenza njengesithako esisebenzayo kumashishini ahlukeneyo.Iimpawu zayo ezikhethekileyo kunye nokusetyenziswa okubanzi kuyenza ibe yinto ebalulekileyo ekudityanisweni kwezinto eziphilayo, amayeza, idayi kunye neeplastiki.Sizinikele ekukuboneleleni ngeyona NTA ikumgangatho ophezulu, eyenziwe ngokuchanekileyo nangokuthobela imigangatho yoshishino.
