Txais cov txheej txheem kev npaj siab, xws li hauv-situ polymerization, emulsion polymerization, microencapsulation, thiab lwm yam, kom ua tiav cov khoom zoo ntawm cov nplaim hluav taws thiab cov kua nplaum thiab txhim kho cov khoom zoo thiab kev ua haujlwm ruaj khov.
11. Kev nthuav dav ntawm Daim Ntawv Thov Fields ntawm AFSM Glue: Nrog rau kev saib xyuas ntxiv rau kev nyab xeeb hluav taws los ntawm tib neeg, daim ntawv thov teb ntawm AFSM kua nplaum yuav txuas ntxiv. Nyob rau hauv lub neej yav tom ntej, ntxiv rau cov teb uas twb muaj lawm xws li aerospace, electronics thiab cov khoom siv hluav taws xob, kev tsim kho, kev thauj mus los, thiab lwm yam., nws tseem yuav siv dav hauv cov haujlwm tshiab xws li lub zog tshiab, lub tsev ntse, cov khoom siv kho mob, thiab lwm yam.
12. Txhim khu kev tshawb fawb ntawm nplaim hluav taws retardant Mechanism: Ua qhov kev tshawb fawb tob txog cov nplaim hluav taws xob hluav taws xob ntawm cov nplaim hluav taws xob hauv AFSM kua nplaum, nthuav tawm cov kev cai sib cuam tshuam ntawm cov nplaim hluav taws thiab cov kua nplaum, thiab muab cov kev xav ntau dua.

Yog xav paub ntxiv txog cov lus qhia ua tiav rau daim ntawv thov cov nplaim hluav taws kub hnyiab hauv cov kua nplaum ntawm cov khoom siv hluav taws kub tsis siv neeg, koj tuaj yeem them mus ntsib Deepmaterial ntawm https://www.adhesivesmanufacturer.com/ yog xav paub ntau info.
