Zinthu zakuthupi
Mu kaphatikizidwe wa zipangizo ndi intermediates, tinthu kukula kwa zinthu ndi osiyana, ndi fineness wa ufa si yunifolomu, amene depreciated kapena anakanidwa.Chifukwa zomwe zili mu fiber za zomera zimaposa muyezo, mtengo wa ufa wamankhwala sungathe kuwongolera.Kukula kwa tinthu tamapiritsi ndi kosiyana, kukula kwa mapiritsi ndi kosiyana, ndipo zomwe zimapangidwira ndizosiyana.Pali mitundu pafupifupi chikwi.Okhwima zofunika, sangathe kuwononga, kuwonongeka, monga kapisozi pellets zopangira.
Njira yopanga
Zopangira zopangira - kusefera - crystallization - kupatukana - kuyanika - sieving - kuyika kwamkati - kuyika kwakunja
M'zigawo zopangira: Malinga ndi kusungunuka kwa zigawo zosiyanasiyana za mankhwala azitsamba aku China mu zosungunulira, chosungunulira chokhala ndi zosungunulira zazikulu zogwira ntchito komanso kusungunuka kwapang'onopang'ono kwa zigawo zomwe siziyenera kusungunuka zimasankhidwa, ndipo njira yosungunulira zigawo zogwira ntchito. kuchokera ku minofu ya mankhwala amatchedwa zosungunulira m'zigawo.
Sefa: kusefera amatanthauza unit ntchito kulekanitsa olimba nkhani particles inaimitsidwa mu mpweya kapena madzi, ntchito porous zakuthupi (sefa sing'anga) podutsa mpweya kapena madzi mu kuyimitsidwa (sefa slurry) (sefera), intercepting The olimba particles ( fyuluta zotsalira) zomwe zimatsika zimakhalabe pa fyuluta sing'anga kupanga keke ya fyuluta.
Crystallization: Pamene njira yotentha yodzaza ndi utakhazikika, kusungunuka kwa solute kumachepa ndipo yankho limakhala lapamwamba kwambiri, kotero kuti solute imalowa mu mawonekedwe a makhiristo.
Kulekana: Kulekana mouma ndi konyowa.
Kuyanika: Gwiritsani ntchito kutentha kusungunula chinyezi (chinyontho kapena zosungunulira zina) muzinthu zonyowa, ndipo gwiritsani ntchito mpweya kapena vacuum kuchotsa chinyezi kuti mupeze zouma.
Kuwunika: Zinthuzo zimasanjidwa ndi kukula kwa tinthu.
Kupaka: Kumaliza kumaliza.
Cholinga chowunikira
Mu kaphatikizidwe wa intermediates, tinthu kukula kwa zinthu ndi osiyana, ndi fineness ufa si yunifolomu, amene depreciated kapena anakanidwa.Zinthuzo ndi zomata, zokongoletsedwa, zotsekedwa ndi zotsekedwa, mawonekedwe a pamwamba pa zinthuzo, ndi kuchulukana kwakukulu kumafunika kwambiri, ndipo sizingawonongeke kapena kuonongeka, monga zopangira za makapisozi ndi pellets.
