I-Tetraethylenepentamine (TEPA) sisithako sekhemikhali esisetyenziswa ngeendlela ezahlukeneyo esinoluhlu olubanzi lwezinto ezisetyenziswayo ezigubungela amacandelo amaninzi emizi-mveliso. Nazi iindlela eziphambili zokusetyenziswa kwe-tetraethylene pentamine:

1. Iiresini zokwenziwa kunye neeplastiki
I-Polyamide Resin: I-Tetraethylenepentamine isetyenziselwa ukwenza i-polyamide resin, i-thermoplastic enamandla aphezulu kunye nokumelana nobushushu.
I-Cation Exchange Resin: Isetyenziselwa ukwenza ii-cation exchange resins, ezidlala indima ebalulekileyo kwiinkqubo zokunyanga nokucoca amanzi.
2. Izongezo
Izongezo zeoyile yokuthambisa: Ukuphucula ukusebenza kweoyile yokuthambisa kunye nokunciphisa ukungqubana kunye nokuguguleka.
Izongezo zeoyile yepetroli: Ukuphucula ukusebenza kakuhle komlilo kunye nokusebenza kweoyile yepetroli.
3. Iarhente yokunyanga kunye ne-accelerator
I-Epoxy Resin Curing Agent: Isetyenziselwa ukunyanga i-epoxy resin nokuphucula ubulukhuni bayo kunye nokumelana neekhemikhali.
I-Rubber vulcanization accelerator: Ikhawulezisa inkqubo yerabha ye-vulcanization kwaye iphucula umgangatho kunye nokuqina kweemveliso zerabha.

4. Iimpendulo ezibangelwa yintsimbi

I-Tetraethylenepentamine idla ngokusetyenziswa njengesiseko se-organic kwi-organic synthesis kuba inee-amino units ezininzi kwaye inokwenza ii-coordination bonds ezininzi. I-amino unit yayo inokwenza i-complex ene-metal ions kwaye inamandla okulungelelanisa kunye nokukhetha okuhle. Isetyenziswa kakhulu kwi-metal catalytic reactions kwaye inezicelo ezilungileyo ekubambeni nasekuhlukaniseni ii-ion zesinyithi.
5. Ezinye izicelo
I-anion exchange resin: Isetyenziselwa ukwenza i-anion exchange resin yokucoca amanzi.
I-Complexometric titration: Isetyenziselwa i-complexometric titration yezinto zesinyithi ezifana nobhedu, i-zinc kunye ne-nickel kusetyenziswa indlela ye-current endpoint.
Impendulo yeSaponification: Ithatha inxaxheba kwinkqubo yesaponification yezinto ezine-asidi.
Isixhobo sokucoca nokukhupha amanzi emzimbeni: sisetyenziswa kwinkqubo yokucoca nokukhupha amanzi emzimbeni yerabha yokwenziwa kunye ne-resin.
