Kuchulukana Kwambiri kwa Paper Pulp
Lonnmeterapanga ndi kupanga zida zoyezerakachulukidwe kachulukidwe ka pepala zamkati, mowa wakuda ndi mowa wobiriwira. Ndi zotheka kudziwa kachulukidwe wa zinthu zosungunuka kapena zosasungunuka kudzera mu mita imodzi yokha yoyikidwa pamzere. Timapereka njira zothetsera kachulukidwe ndi muyeso wa ndende pazogwiritsa ntchito ngati zakumwa zakuda, zobiriwira zamasamba zapapepala. Komanso zamkati kachulukidwe mamita amatha kuyeza kachulukidwe laimu matope ngati popanda lalikulu-kakulidwe particles ndi katundu thovu.
N'chifukwa Chiyani Mukufunika Kuyezera Kachulukidwe Kosalekeza?
Zosiyanasiyana zamkatipakupanga mapepala kumabweretsa zoopsa zomwe zingachitike pakusakhazikika kwa zinthu zomaliza ndikuwonjezera mtengo wopangira mapepala. Zamkati zamapepala zimakhala ndi kuyimitsidwa kwa fiber m'madzi mofanana. Kusafanana mu kachulukidwe kumakhudza ntchito yonse yopanga mapepala.
Kusinthasintha kosinthikawa zamkati amasiya mamasukidwe akayendedwe ake kusintha ndi mlingo wa kukameta ubweya, kuwonjezera wosanjikiza wina wa zovuta kuti mosalekeza kachulukidwe muyeso. Zolakwika zimakula kwambiri chifukwa cha mpweya wotsekeka, womwe umakhala ngati thovu mu osakaniza, zomwe zimapangitsa kuwerenga zabodza ndikuchepetsa kulondola.
Njira zachikhalidwe zomwe zimagwiritsidwa ntchito poyezera kachulukidwe nthawi zambiri zimakhala zolondola poyang'anizana ndi kusintha kwa magwiridwe antchito. Mwachitsanzo, njira za gravimetric sizoyenera kuwunika mosalekeza chifukwa chachikhalidwe chofuna kugwira ntchitondichiwopsezo cha zolakwika za zitsanzo.
Kuyeza Mfundo mu Paper Pulp Process
Pezani zidziwitso kuchokera pazithunzi zomwe zili pamwambapa pakupanga mapepala, pali mfundo zisanu ndi ziwiri zoyika mita ya kachulukidwe ka mankhwala kuti muthe kukhathamiritsa kwathunthu. Iwo amagwira ntchito mu mbali zotsatirazi:
1. Kusungunuka kwa mowa wakuda m'madzi;
2. Kuchuluka kwa mowa wobiriwira kapena kuyang'anira ndende;
3. Kachulukidwe ka mowa woyera kapena kuyang'anira ndende;
4. Laimu slurry kachulukidwe kapena ndende kuwunika;
5. Ofooka mowa wakuda kachulukidwe kapena ndende.
Njira ya kraft imatembenuza nkhuni kukhala zamkati zamatabwa, momwe zakumwa zakuda kapena zakumwa zoledzeretsa zimapangidwa ndi zamkati zamatabwa. Kenako mowa wakuda umakonzedwa mpaka mowa wobiriwira upangike. Kuphatikiza apo, chitha kusinthidwa kukhala chakumwa choyera powonjezera mkaka wa mandimu kuti uchiritsidwe. Chifukwa chake, kachulukidwe kapena kuwongolera ndende pamiyezo yomwe ili pamwambayi ndi yofunika kwambiri pakuwongolera bwino komanso kuwongolera mtengo.
Analimbikitsa Density Meter
Lonnmeterzamkati kachulukidwe mitandi njira yabwino yowunikira mosalekeza kachulukidwe pakuwongolera molondola, ndikuwerengera zolondola kwa ogwiritsa ntchito munthawi yeniyeni. Kuwerenga kwake mwatsatanetsatane kumatha kufika ±0.002g/cm³, ndipo kuchuluka kwake kumagwera mu 0-2 g/cm³. Zotulutsa zimaperekedwa mu siginecha ya 4-20 mA. Kuti ogwiritsa ntchito amatha kusintha magawo opangira nthawi yomweyo kuti akhale okhazikika komanso osasinthasintha, monga kuwonjezera pa zamkati zamapepala, zomwe zili m'madzi komanso kuchuluka kwa chipwirikiti.
Kuphatikiza apo, kuyang'anira nthawi yeniyeni ya zamkati zamapepala kumapindulitsa kupeza zolakwika pakukonza, monga kusasinthika kosinthika, kusafanana kwa zamkati zamapepala komanso kuwonongeka kwa zida. Kenako njira zina zitha kuchitidwa mwachangu kupeŵa kutayika kwa kupanga ndi zinthu zopanda pake.
Lumikizanani ndi mainjiniya athu kuti mumve zambiri za mita ya kachulukidwe zamkati, ndipo mutha kupeza malingaliro okhudza kusankha mita yoyenera ya inline density. Funsani mtengo waulere tsopano!
