(China) YYP116-2 Woyesa Kudziyimira Pawokha ku Canada
Choyesera cha Canada Standard Freeness chimagwiritsidwa ntchito poyesa kuchuluka kwa kusefera madzi kwa madzi osungunuka a zamkati zosiyanasiyana, ndipo chimafotokozedwa ndi lingaliro la freeness (CSF). Kuchuluka kwa kusefera kumawonetsa momwe ulusi ulili pambuyo popukutidwa kapena kupukutidwa bwino. Chida choyezera ufulu wamba chimagwiritsidwa ntchito kwambiri mu njira yopukutira mapepala, kukhazikitsa ukadaulo wopanga mapepala ndi kuyesa kosiyanasiyana kwa ma pulping a mabungwe ofufuza za sayansi.
Ndi chida chofunikira kwambiri choyezera popayira ndi kupanga mapepala. Chidachi chimapereka mtengo woyesera woyenera kuwongolera kupanga kwa phala la matabwa ophwanyidwa. Chingagwiritsidwenso ntchito kwambiri pakusintha kwa kusefa kwa madzi a mankhwala osiyanasiyana panthawi yoponda ndi kuyeretsa. Chimasonyeza momwe pamwamba pa ulusi ulili komanso momwe umatupa.
Kumasuka kwa miyezo ya ku Canada kumatanthauza kuti pansi pa zomwe zafotokozedwa, pogwiritsa ntchito kuyesa mphamvu ya kuyimitsidwa kwa madzi a slurry ya 1000 mL, kuchuluka kwake ndi (0.3 + 0.0005)%, kutentha ndi 20 °C, voliyumu (mL) ya madzi omwe akuyenda kuchokera mu chubu cha mbali ya chipangizocho imatanthauza kuchuluka kwa CFS. Chidacho chimapangidwa ndi chitsulo chosapanga dzimbiri, chimakhala ndi ntchito yayitali.
Choyesera kumasuka chimakhala ndi chipinda chosefera ndi funnel yoyezera yomwe imazungulira mofanana, imagawidwa pa bulaketi yokhazikika. Chipinda chosefera madzi chimapangidwa ndi chitsulo chosapanga dzimbiri. Pansi pa silinda, pali mbale yotchingira chitsulo chosapanga dzimbiri yokhala ndi mabowo ndi chivundikiro chapansi chotseka chopanda mpweya, cholumikizidwa ndi tsamba lotayirira mbali imodzi ya dzenje lozungulira ndikulimanga mwamphamvu mbali inayo. Chivundikiro chammwamba chimatsekedwa, chikatsegulidwa chivindikiro chapansi, zamkati zimatuluka.
Silinda ndi funnel yozungulira yosefera zimathandizidwa ndi ma flange awiri opangidwa ndi makina pa bulaketi motsatana.
