M'mafakitale opangira mankhwala ndi filimu, polima yosungunuka yomwe imagwiritsidwa ntchito popanga nthawi zambiri imakhala ndi zonyansa zamakina ndi tinthu tating'ono ta gel osasungunuka.Chifukwa chake, ndikofunikira kusefa polima yosungunula pogwiritsa ntchito zinthu monga spin pack fyuluta, waya wa mesh, fyuluta yamakandulo, diski yamasamba musanazungulire kapena kupanga filimu kuti muchotse zonyansa ndikuwongolera magwiridwe antchito a kupota kapena kupanga filimu.Izi zithanso kutalikitsa moyo wa zigawo zikuluzikulu.
Panthawi yothamanga kwambiri kapena kupanga mafilimu, zosefera zimatha kupanga kukana kwakukulu, zomwe zimapangitsa kutentha kwamphamvu komanso kutentha kwa polima yosungunuka.Izi zimathandiza kusakaniza bwino sungunula polima ndikusintha mawonekedwe ake a rheological.
Kupititsa patsogolo luso la kupota kapena filimu kusungunula polima ndi kukulitsa moyo wa zigawo zopota kapena ma disks a masamba, makina osungunuka osungunuka (pre-filter) akhoza kuikidwa mu payipi yosungunuka.Fyuluta iyi imatha kuchotsa tinthu tating'onoting'ono ndi zonyansa zamakina kuchokera kusungunuka ndikuwonetsetsa kuti kusakanikirana kofananako kusungunuke.Makina osefera amakhala ndi zipinda ziwiri zosefera ndi valavu yanjira zitatu yomwe imalumikizana ndi payipi yosungunuka.Valavu yanjira zitatu imatha kusinthidwa nthawi ndi nthawi kuti isinthe pakati pa zipinda zosefera, kuonetsetsa kusefera kosalekeza.Nyumba za zipinda zosefera zimatayidwa kuchokera kuzitsulo zosapanga dzimbiri.Makina osefera am'dera lalikulu amapangidwa ndi zosefera zamakandulo zingapo.Zosefera za makandulo zimathandizidwa ndi masilinda apakati okhala ndi perforated ndipo zimakhala ndi zigawo ziwiri kapena zingapo zazitsulo zoluka zachitsulo kapena ma sintered zitsulo ufa zimbale pa wosanjikiza wakunja.
Titha kupereka mawonekedwe osiyanasiyana a spin pack fyuluta, waya wa mauna, fyuluta ya makandulo ndi ma disc amasamba amitundu yosiyanasiyana.Mlingo wa kusefera ndi zinthu zomwe zimagwiritsidwa ntchito zitha kukonzedwa malinga ndi zomwe makasitomala amafuna.Timapanga mchenga wachitsulo wokhala ndi maphikidwe osiyanasiyana ogwiritsira ntchito mkati mwa thupi la spin pack pamzere wopota wa fiber fiber, monga poliyesitala ndi nayiloni.Titha kupereka mchenga wachitsulo wamitundu yosiyanasiyana ya mauna, monga 10/20, 20/30, 30/40, 40/60, 60/80, 80/100, 100/120, ndi ma meshes 120/170.
Popanga oriented polyamide film (BOPA), oriented polyester film (BOPET), and oriented polyolefin film (BOPP), m'pofunika kugwiritsa ntchito zosefera ma disc kuchotsa ma gels, kuwonjezera condensing agents, catalysts, ndi zonyansa zina zolimba kuchokera ku ma polima. .Titha kupereka zimbale masamba makulidwe osiyanasiyana ndi kusefera mlingo wopangidwa kuchokera zipangizo zosiyanasiyana fyuluta, monga zosapanga dzimbiri CHIKWANGWANI sintered felts, Mipikisano wosanjikiza zosapanga dzimbiri ma meshes sintered, kapena sintered zitsulo ufa.
