Filtration System for Sungunulani Polymer kusefera

Pofuna kupititsa patsogolo ubwino wa polima yosungunula ndikutalikitsa moyo wautumiki wa zigawo za paketi ya spin, fyuluta yosalekeza yosungunuka (CPF) imayikidwa pa chitoliro chachikulu chosungunuka.Iwo akhoza kuchotsa makina zosafunika particles ndi m'mimba mwake wamkulu kuposa 20-15μm mu Sungunulani, komanso ali ndi ntchito ya homogenizing kusungunula.Nthawi zambiri makina osefera amakhala ndi zipinda ziwiri zosefera, ndipo mavavu anjira zitatu amalumikizidwa ndi payipi yosungunuka.Ma valve a njira zitatu amatha kusinthidwa nthawi ndi nthawi kuti asinthe kugwiritsa ntchito zipinda zosefera kuti zitsimikizire kusefa kosalekeza.Nyumba ya chipinda cha fyuluta imaponyedwa mu chidutswa chimodzi ndi chitsulo chosapanga dzimbiri.Zosefera zazikuluzikulu zimapangidwa ndi zinthu zingapo zosefera zamakandulo.Chojambulira chamakandulo chimathandizidwa ndi silinda yapakati yokhala ndi mabowo, ndipo wosanjikiza wakunja uli ndi mauna amodzi kapena angapo osanjikiza zitsulo kapena sintered metal powder disc kapena zitsulo zosanjikiza zingapo & sintered fiber kapena sintered metal wire mesh, etc. muzosefera zosiyanasiyana zomwe zimatengera zofunikira pazogulitsa zomaliza.

Nthawi zambiri pali mitundu yosiyanasiyana ya kusefera, monga Horizontal mosalekeza kusefera dongosolo, ofukula mosalekeza kusefera dongosolo.Mwachitsanzo, panthawi ya PET chips kupota ndondomeko, ofukula kandulo-mtundu fyuluta mtundu amakonda akufuna, amene ali ndi kusefera dera 0.5㎡ pachimake kandulo.Pali masanjidwe omwe amagwiritsidwa ntchito nthawi zambiri a 2, 3, kapena 4 makandulo, ofanana ndi malo osewerera a 1, 1.5, kapena 2㎡, ndipo mphamvu zofananira zosungunula ndi 150, 225, 300 kg/h.Dongosolo la kusefera koyima lili ndi kukula kwakukulu komanso magwiridwe antchito ovuta, koma ali ndi maubwino ambiri kuchokera pamawonekedwe azinthu: (1) Lili ndi mphamvu yayikulu yotenthetsera, kusinthasintha kwakung'ono kwa kutentha kwasungunuka, ndipo palibe madera akufa pamene zinthu zikuyenda.(2) Maonekedwe a jekete yotchinjiriza ndi yololera, ndipo kutentha kumakhala kofanana.(3) Ndikwabwino kukweza pachimake fyuluta pamene kusintha fyuluta.

Kusiyana kwa kuthamanga kusanachitike komanso pambuyo pa fyuluta yomwe yangogwiritsidwa ntchito kumene ndiyotsika.Pamene nthawi yogwiritsira ntchito ikuwonjezeka, mabowo apakati osefera amatsekedwa pang'onopang'ono.Kusiyana kwa kuthamanga kukafika pamtengo wokhazikika, mwachitsanzo, monga tchipisi ta PET, nthawi zambiri chiwongola dzanja chimakhala cha 5-7MPa, chipinda chosefera chiyenera kusinthidwa.Kusiyanitsa kololedwa kukapitilira, ma mesh a fyuluta amatha kupindika, kukula kwa ma mesh kumawonjezeka, ndipo kusefera kumachepa mpaka sefayi itasweka.Sefa yapakati iyenera kutsukidwa musanagwiritsenso ntchito.Kumveka bwino kwa zotsatira zake kumatsimikiziridwa bwino ndi kuyesa kwa "bubble test", koma kungathenso kuweruzidwa potengera kusiyana kwa kuthamanga kusanachitike komanso pambuyo pa fyuluta yatsopano yosinthidwa.Nthawi zambiri, fyuluta ya kandulo ikang'ambika kapena kutsukidwa nthawi 10-20, siyenera kugwiritsidwanso ntchito.

Mwachitsanzo, zosefera za Barmag NSF zotsatizana, zimatenthedwa ndi nthunzi ya Biphenyl mu jekete, koma kutentha kwamadzimadzi otengera kutentha sikuyenera kupitilira 319 ℃, komanso kuthamanga kwa nthunzi ya Biphenyl ndi 0.25MPa.Kuthamanga kwakukulu kwapangidwe kwa chipinda chosefera ndi 25MPa.Kusiyana kwakukulu komwe kumaloledwa musanayambe komanso pambuyo pa fyuluta ndi 10MPa.
