I-Hydroxyethylenediamine inamathuba emakethe abanzi

Izinkambu Zokusetshenziswa: I-Hydroxyethylenediamine isetshenziswa kabanzi ezimonyweni, emithini, ezibulala-zinambuzane, epulasitikini nakwezinye izinkambu. Ngokuthuthuka kwezimboni ezahlukahlukene, isidingo sayo semakethe siyaqhubeka nokukhula.
Intengo yemakethe: Ngokwezimo zakamuva zemakethe, intengo ye-hydroxyethylethylenediamine iyashintshashintsha. Isibonelo, intengo eHubei ngo-Okthoba 2024 ingu-53,000 yuan/ton, kanti intengo eShandong ingu-21,300 yuan/ton. Umehluko wentengo phakathi kwezifunda ezahlukene kanye nemikhiqizo ehlukene mkhulu.
Umkhuba Wemakethe: Ngokuthuthuka okuqhubekayo kwemboni yamakhemikhali yomhlaba wonke kanye nokuthuthukiswa kwezindinganiso zokuphila zabantu, amathuba emakethe e-hydroxyethylethylenediamine abanzi kakhulu. Esikhathini esizayo, ngokwanda okuqhubekayo kwamasimu okusetshenziswa kanye nokukhula okuqhubekayo kwesidingo semakethe, isilinganiso semakethe se-hydroxyethylethylenediamine kulindeleke ukuthi sikhule kakhulu.
Ngamafuphi, njengezinto ezibalulekile zamakhemikhali aphilayo, i-hydroxyethylethylenediamine isetshenziswa kabanzi emikhakheni eminingi futhi inethuba elihle emakethe. Kodwa ngesikhathi esifanayo, intengo yayo yemakethe nayo iyashintshashintsha, futhi kuyadingeka ukunaka kakhulu izitayela zemakethe ukuze kwakhiwe amasu okuthenga nokuthengisa afanele.

Ukusetshenziswa kwe-Hydroxyethylenediamine

I-Hydroxyethylethylenediamine, eyaziwa nangokuthi i-ejenti yokwelapha No. 1, iyinhlanganisela yezinto eziphilayo esebenza ngezindlela eziningi enokusetshenziswa okubanzi, ikakhulukazi okuhlanganisa izici ezilandelayo:

Izinto zokusetshenziswa zamakhemikhali: Njengezinto zokusetshenziswa zamakhemikhali ezibalulekile kwezokwelapha kanye nezansuku zonke, zingasetshenziswa ukukhiqiza izithibi zokugqwala, iziqinisi zokukhanya, izisheshisi ze-vulcanization, njll.
I-Surfactant: Yiyona nto eyinhloko yokusetshenziswa ekukhiqizweni kwama-surfactants e-cationic kanye ne-zwitterionic imidazoline, futhi lolu hlobo lwe-surfactant lubalelwa engxenyeni enkulu yamandla okukhiqiza aphelele.
I-epoxy resin curing agent: Njenge-ejenti yokwelapha yegumbi enobuthi obuphansi ye-epoxy resin, isetshenziswa ne-epoxy resin futhi isetshenziswa kabanzi ekuhlanganiseni izingxenye zensimbi nezingezona ezensimbi, ukulungiselela izembozo ze-epoxy ezilwa nokugqwala, njll.
Okunye ukusetshenziswa: Ingasetshenziswa futhi ukukhiqiza udayi, ama-resins, ama-raber, ama-flotation agents, izibulala-zinambuzane, kanye nezithasiselo zokugcoba, ama-metal ion sealants, njll.
Ngamafuphi, i-hydroxyethylethylenediamine inezinhlobo eziningi zezicelo emikhakheni eminingi ngenxa yezakhiwo zayo zamakhemikhali ezihlukile kanye nokuguquguquka kwazo.
