Chiyambi: Kufunika Kokulira kwa Diacetone Acrylamide mu Ukadaulo Wapamwamba wa Polymer

Kufunika kwa zipangizo za polima zogwira ntchito bwino kukupitirirabe kukwera m'mafakitale monga zokutira, zomatira, nsalu, mankhwala omangira, inki zosindikizira, ndi ma polima apadera. Opanga akufunafuna ma monomer ogwira ntchito omwe angawongolere:

• Kulimba kwa filimu
• Luso lolumikiza
• Kukana madzi
• Mphamvu ya makina
• Kukhazikika kwa mankhwala
• Kuchita bwino kwa chilengedwe

Chimodzi mwa zinthu zofunika kwambiri zomwe zathandiza kwambiri ndi ichi: Diacetone Acrylamide (DAAM).

Diacetone Acrylamide ndi monomer ya acrylic yogwira ntchito yokhala ndigulu la ntchito ya ketone, zomwe zimalola ma polima okhala ndi DAAM kuti azitha kuchita zinthu mogwirizana ndi ma crosslink oyenera mongaadipic acid dihydrazide (ADH).

Mankhwala apaderawa amapangitsa DAAM kukhala yofunika popanga:
