(China) YYP116-2 Muedzo weKusununguka weCanada
Muchina weCanadian Standard Freeness Tester unoshandiswa pakuona mwero wekusefa mvura muzvimedu zvakasiyana-siyana zvemvura, uye unoratidzwa nepfungwa yekusununguka (CSF). Mwero wekusefa unoratidza kuti fibers dzakaita sei mushure mekusefa kana kukuya zvakanaka. Chishandiso chekuyera kusununguka chakajairwa chinoshandiswa zvakanyanya mukuita kwekupa mapepa, kutanga tekinoroji yekugadzira mapepa uye kuyedza kwakasiyana-siyana kwekupa mapepa kwemasangano ekutsvagisa kwesainzi.
Ichi chishandiso chakakosha chekuyera pulping nekugadzira mapepa. Chishandiso ichi chinopa chiyero chekuyedza chakakodzera kudzora kugadzirwa kwepulp yehuni yakapwanywa. Chinogona zvakare kushandiswa zvakanyanya pakuchinja kwekusefa kwemvura yemakemikari akasiyana-siyana panguva yekurova nekunatsa. Chinoratidza mamiriro epamusoro pefiber uye mamiriro ekuzvimba.
Kusununguka kweCanada kunoreva kuti pasi pemamiriro akatarwa, uchishandisa kuyedza kushanda kwemvura inotsvedza ye1000 mL, huwandu hwemvura huri (0.3 + 0.0005) %, tembiricha iri 20 °C, huwandu (mL) hwemvura inoyerera kubva pachubhu yerutivi rwechishandiso hunoreva kukosha kweCFS. Chishandiso ichi chakagadzirwa nesimbi isina ngura, chinoshanda kwenguva refu.
Chiyedzo chefreeness chine kamuri yekusefa nefunnel yekuyera iyo inotenderera zvakaenzana, yakakamurwa yakaiswa pabhuraketi rakagadzika. Kamuri yekusefa mvura yakagadzirwa nesimbi isina ngura. Pasi pesirinda, pane ndiro yesimbi isina ngura ine maburi uye chifukidziro chepasi chinovhara mweya, chakabatana neLeaf-leaf kune rumwe rutivi rwegomba rakatenderera uye chinosungirirwa zvakasimba kune rumwe rutivi. Chivharo chepamusoro chinovharwa, kana chivharo chepasi chakavhurwa, pulp inobuda.
Silinda nefunnel ine denderedzwa remasefa zvinotsigirwa nemabhatani maviri akasungirirwa nemachina ari pabhureki zvichiteerana.
