Metal Powder for Polymer Filtration

PET PA PP wosungunuka wa polima wonyezimira amayenera kusefedwa musanayambe kupota ulusi wamankhwala kuti muchotse zonyansa ndi tinthu tating'onoting'ono ta gel osungunuka kuti tipewe kutsekeka kwa dzenje la spinneret, kupititsa patsogolo mtundu wa PET PA filament fiber, monga ulusi wa POY FDY. ;pamene polima yosungunuka imayenda pamtundu wa spin pack screen, kukana kumapangidwa, kotero kuti kusungunula kumatulutsa kutentha, kutentha kumakwera, ndipo mawonekedwe a rheological of the melt amakhala bwino.Panthawi imodzimodziyo, kusungunula kumasakanizidwa mokwanira kuti ateteze kusiyana kwa mamasukidwe akayendedwe pakati pa kusungunuka;kusungunuka kumagawidwa mofanana ku dzenje laling'ono lililonse la spinneret;ndi kuwonjezeka kwa nthawi yogwiritsira ntchito fyuluta ya spin pack, zonyansa mu mesh pack fyuluta wosanjikiza zidzawonjezeka, ndipo kupanikizika kwa msonkhano kudzawonjezeka pang'onopang'ono.Kuthamanga kumawonjezeka mofulumira, ndipo moyo wautumiki wa msonkhano ndi waufupi.Pamene msonkhano ukukwera kukakamiza kwinakwake, m'pofunika kusintha msonkhanowo panthawi yake, apo ayi, pampu ya metering imaphwanyidwa, kapena spinneret imapunduka, kapena kutayikira kumachitika.

Kusankhidwa kwa zigawo zoyenera zosefera ndikofunikira kwambiri pakupota ulusi wopangira, ndipo media yabwino yosefera ndiyofunikira kwambiri.M'kati mwa chitukuko cha kupota, ndi njira yopezera njira yabwino yometa ubweya wa ubweya.Zida zambiri zosefera zodziwika ndi monga mchenga wa m'nyanja, zometa zitsulo, mikanda yagalasi, mbale zachitsulo zopindika, ndi tinthu tachitsulo tosawoneka bwino.

Kuphatikiza pa kutsika mtengo, njira yabwino yosefera iyenera kukhala ndi porosity yayikulu pazovuta zomwe zimakumana ndi kusefera kwa polima.Pofuna kukhala ndi porosity yayikulu, bedi la tinthu tating'ono ta ma polima otentha kwambiri ndi chizolowezi chopanga gel osakaniza omwe amadziunjikira ndikuchepetsa kusefera bwino kwa media media.Chifukwa chake, zinthu zosefera zachitsulo siziyenera kuyambitsa kapena kuthandizira kupanga gel osakaniza.

Imapezeka kuti ipeze mchenga wa m'nyanja, koma imakhala yolimba kwambiri chifukwa chakuti kukula kwa tinthu tating'onoting'ono kumalepheretsa ma capillaries mu spinnerets.Kuonjezera apo, malo enieni a mchenga wa m'nyanja ndi ochepa komanso ochepa kwambiri a porosity pa voliyumu iliyonse ya paketi, chifukwa chake paketiyo idzakwera kwambiri.Ufa wachitsulo wosapanga dzimbiri womwe umakonzedwa m'mikhalidwe yodziwika bwino umakhala ndi malo osakhazikika omwe molingana ndi kachulukidwe kakang'ono kakuwoneka bwino, umapangitsa kuti kusefa kwake kukhale kothandiza kwambiri;pansi pa zovuta zogwirira ntchito, imawonetsa kachulukidwe kowoneka bwino ndikuwonjezera kukana kukakamiza kuti muzitha kusefera bwino komanso kugwa pang'ono kapena kugwa.
