I-Meltblown nonlukeixabiso liphakathi, ngelixa ukusebenza kokumelana okuhle kakhulu ne-hydrolysis kunye ne-asidi kunye nokugqwala kwe-alkali, okusetyenziswa kakhulu kwiimfuno zobushushu aziphezulu, umxholo wokufuma uphezulu kwiimeko zokusebenza.
Ngokubanzi, ukumelana nobushushu be-polyester fiber kuphakathi kwe-130℃ kunye ne-150℃. Ukuze koyiswe imeko yokuncitshiswa kwefelthi eqhelekileyo ebhobozwe ngenaliti ye-polyester enokumelana nobushushu obungaphezulu kwe-130℃ ixesha elide, ifelthi entsha yesihluzo enobushushu obusebenzayo be-150℃ ~ 170℃ iyenziwa, ukuze kuthintelwe inkunkuma ebangelwa kukusetyenziswa kwezinto zesihluzo ezinobushushu obuphezulu phantsi kweemeko ezithile zokusebenza.
I-needled felt iphucula ukuchaneka kokuhluzwa kwezinto zokucoca ifayibha yepolyester kwaye inciphisa ukuhla koxinzelelo, kwaye inefuthe lokuhluzwa komphezulu wezinto zokucoca ezigqunyiweyo. Kuluhlu lwezihluzo zobushushu obuphakathi nobuqhelekileyo, i-polypropylene needled felt inokumelana nobushushu obuphantsi, ukumelana okuphantsi kokusebenza kwaye igcina amandla. Ukongeza kwiingenelo ze-felt filter eqhelekileyo, kwaye ukumelana nokuguguleka kulungile kakhulu, kunye nomlinganiselo weendleko eziphezulu kwaye iba linani elikhulu leentlobo ze-felt filter.
I-acrylic fiber acupuncture filter felt ubushushu obuyi-140 ~ 160 degrees Celsius, ukusetyenziswa kwefayibha engeniswayo, yeyona ndlela ilungileyo yokumelana ne-asidi, i-alkali kunye ne-hydrolysis ubushushu obuphakathi bokucoca.
Singoochwephesha ekuveliseni i-meltblown nonwoven, wamkelekile ukubonisana ~
