Pokonza chakudya, kuyanika kwa batri ya lithiamu, ndi mafakitale onyamula katundu, Nsalu ya PTFE yotentha kwambiri imagwiritsidwa ntchito kwambiri pazinthu zake zopanda ndodo komanso zosagwira kutentha. Koma nchiyani chimatsimikizira ubwino ndi moyo wa nkhaniyi? Gawo lapansi.
Monga katswiri wopanga nsalu za PTFE zotentha kwambiri , Jiangsu Aokai New Materials akufotokoza chifukwa chake nsalu ya fiberglass yopanda alkali ndiyoyenera kufananiza gawo lapansi. Zake zapadera zakuthupi ndi zamankhwala zimakwanira bwino kwambiri zokutira za PTFE komanso zovuta zogwirira ntchito, zopatsa mphamvu zomangira zapamwamba komanso kukhazikika kwamagulu onse.
Kugwirizana kwa Chemical - Kupanga Milatho Yokhazikika ya Molecular
PTFE imakhala ndi mphamvu zotsika kwambiri, zomwe zimapangitsa kuti zikhale zovuta kutsatira zida zambiri. Ndicho chifukwa chake makampani amagwiritsa ntchito silane coupling wothandizila monga molecular mlatho - izo zomangira mankhwala ndi fiberglass nsalu mbali imodzi ndi PTFE zokutira mbali inayo.
Pochita izi, nsalu za fiberglass zopanda alkali zikuwonetsa zabwino zake:
Nangula wokhazikika komanso wokwanira wolumikizana: Zomwe zili ndi sodium oxide (Na₂O) zimayendetsedwa mosamalitsa pansi pa 0.8% . Magulu a silanol oyera komanso okhazikika (Si-OH) pamwamba pake amatha kupanga zomangira za Si-O-Si mosasunthika ndi ma silane coupling agents.
Imapewa kuwonongeka kwapakati: Nsalu ya fiberglass yapakati-alkali imakhala ndi 11.9% ~ 16.4% alkali chitsulo oxides. Ma ion a alkaliwa amakhala pamalo ochitirapo zinthu ndipo mosalekeza amathyola zomangira za mankhwala monga zopangira zopangira, zomwe zimapangitsa kuti ❖ kuyanika mosavuta - makamaka m'malo otentha ndi achinyezi.
Kukana kwamphamvu kwa dzimbiri kwamankhwala: Kumakana ma reagents ambiri amankhwala kupatula hydrofluoric acid ndi hot concentrated phosphoric acid - imagwira ntchito ngati mafupa okhazikika a anti-corrosion, kutulutsa mpweya wa flue, ndi madera ena ovuta.
Kutchinjiriza kwamagetsi kwabwino kwambiri: Zomwe zili ndi alkali metal oxide zotsika zimapereka ntchito yoziziritsa bwino, zomwe zimapangitsa kukhala gawo lokondedwa kwambiri pamafakitale amagetsi ndi magetsi.
Kutsiliza - Kusankha Kwapamwamba kwa Industrial-Grade PTFE High-Temp Nsalu
Mwachidule, nsalu za fiberglass zopanda alkali zimapereka:
Mankhwala: maziko okhazikika olumikizana, kuonetsetsa kuti zokutira za PTFE sizimachoka.
Mwakuthupi: Kutha kugwira ntchito mokhazikika pansi pa kutentha kwambiri komanso malo owononga.
Ngakhale kuti mtengo wake ndi wokwera pang'ono, ubwino wake mu mphamvu yomatira, moyo wautumiki, ndi kudalirika kwa ntchito kumapangitsa kuti ikhale gawo lapamwamba la nsalu za PTFE zotentha kwambiri..
