Njira yolumikizirana pokonza zinthu za tetrafluoroethylene

Pokonza zinthu za PTFE, nthawi zambiri zimakhala zofunikira kuphatikiza magawo osiyanasiyana azinthu zomwezo kapena kuphatikiza PTFE ndi zinthu zina zachitsulo kapena zopanda zitsulo. Zomatira ndi imodzi mwazosavuta komanso zothandiza. Komabe, popeza mavuto padziko PTFE palokha ndi otsika kuposa zipangizo zina zonse olimba, ndi zosatheka mwachindunji chomangira. Chithandizo chapamwamba cha zinthu za PTFE ndiye chinsinsi champhamvu yolumikizirana.

1. Thupi coarsening ndondomeko

Njira yeniyeni yowumitsa thupi ndi chithandizo cha plasma. Plasma imatchedwanso kutulutsa kowala. Zomwe zimagwiritsidwa ntchito pochiza zinthu zam’mwamba ndi mtundu wa mphamvu yotchedwa cold plasma. Kutulutsa kwapang’onopang’ono pakuthamanga kwamlengalenga kwa 0.13-0.18Mpa kumapanga ma ion amphamvu kwambiri kuti amathire pamwamba pa PTFE ndikupanga mabampu ambiri abwino. Poyerekeza ndi chithandizo chamankhwala, pamwamba pa mankhwalawa amatha kupeza mphamvu zomangirira chifukwa sichilandira mpweya ndi kuwala kwa ultraviolet. Udindo wa.

2. Njira yothandizira mankhwala

Makamaka zikuphatikizapo yokonza mankhwala mankhwala madzi ndi pamwamba mankhwala a PTFE. Zakumwa zochizira mankhwala zomwe zilipo ndi sodium naphthalene treatment liquid ndi liquid sodium ammonia solution. Zakale zimagwiritsidwa ntchito makamaka ku China.

3. Kugwirizana

The PTFE mankhwala amene adutsa pamwamba mankhwala pamwamba ndi zipangizo zomwe zimafuna kugwirizana ndi iwo akhoza chomangira ndi zomatira ambiri.
