Yakanyunguduka isina kurukwamutengo wacho uri pakati nepakati, nepo kushanda kwacho kuchiramba zvakanaka hydrolysis uye acid ne alkali corrosion, zvinonyanya kushandiswa mukupisa kunodiwa kwete kwakakwira, hunyoro hunowanikwa mumamiriro ekushanda akakura.
Kazhinji, kudzivirira kupisa kwepolyester fiber kuri pakati pe130℃ ne150℃. Kuti ikunde dambudziko rekupwanyika kwefelt yakajairwa yepolyester ine needle-roken iyo ine kudzivirira kupisa kweinopfuura 130℃ kwenguva yakareba, firita itsva ine tembiricha yekushanda ye150℃ ~ 170℃ inogadzirwa, kuitira kudzivirira marara anokonzerwa nekushandisa firita yekupisa kwepamusoro pasi pemamwe mamiriro ekushanda.
Felt ine needled inovandudza kurongeka kwekusefa kwepolyester fiber filter uye inoderedza kudonha kwekumanikidzwa, uye ine mhedzisiro yekusefa pamusoro pechinhu chakaputirwa chefirita. Mune akatevedzana emafirita ekupisa ari pakati nepakati nepakati, polypropylene needled felt ine resistance yakaderera yekupisa, resistance yakaderera yekushanda uye inochengetedza simba. Pamusoro pezvakanakira zvefirita yakajairika, resistance yekupfeka yakanaka kwazvo, ine mutengo wakakwira uye inova huwandu hukuru hwemhando dzefirita dzefelt.
Acrylic fiber acupuncture firita yakanzwa tembiricha ye140 ~ 160 degrees Celsius, kushandiswa kwekugadzira fiber inopinzwa kunze kwenyika, ndiyo yakanakisa kuramba acid, alkali uye hydrolysis resistance medium tembiricha firita zvinhu.
Isu tine hunyanzvi mukugadzira zvinhu zvisina kurukwa zvakanyungudutswa, tinokugamuchirai kuti mubvunze ~
