Yaiwisi zamkati lili appreciable kuchuluka kwa lignin ndi ma discoloration, ayenera bleached Zamkati yaiwisi lili appreciable kuchuluka kwa lignin ndi ma discoloration, ayenera bleached kubala kuwala akuda kapena woyera mapepala wokonda mankhwala ambiri. Ulusiwo umasinthidwanso ndikusungunula lignin yowonjezera kuchokera ku cellulose kudzera mu chlorination ndi okosijeni. Sodium Hydrooxide, alkali wamphamvu amagwiritsidwa ntchito pochotsa lignin yosungunuka kuchokera ku ulusi pamwamba. Mankhwala opangira ma bleaching ma pulps amawotchera amawononga zonyansa zopaka utoto koma amasiya zinthu za lignin ndi cellulosic, monga sodium bisulfite, sodium kapena zinki hydrosulfite, calcium kapena sodium hypochlorite, hydrogen kapena sodium peroxide, ndi Sulfur Dioxide-Borol Njira.
Pofuna kuonetsetsa kuti pepala loyera liri lofanana komanso labwino, zowonjezera zowonjezera, dispersants ndi bleaching agents ziyenera kuwonjezeredwa. Monga momwe zimagwiritsidwira ntchito zowonjezera m'makampani a zakudya, zowonjezerazi zimakhala ndi kayendedwe kakang'ono kakang'ono ndipo zimawononga kwambiri.
Ubwino:
? Ikhoza kukhazikitsidwa ndi zipangizo zosiyanasiyana kuti zigwirizane ndi zosowa za ndondomeko
? M'mimba mwake yonse popanda kutsika kwamphamvu kudutsa mita
? Miyezo yokhazikika, yolondola yomwe imayimira kuyenda kwenikweni.
Chovuta:
? Kuthamanga kumakhala kochepa, ndipo chizindikiro chotulutsa chidzasinthasintha kwambiri.
? Njira yowononga kwambiri idzakhudza moyo wautumiki
Lining: Ambiri aiwo amasankha PTFE lining ndi PFA lining.
Electrode: Ta/Pt osankhidwa malinga ndi zinthu zamadzimadzi zosiyanasiyana
Samalirani kwambiri kukhazikika pakuyika kachipangizo kakang'ono ka electromagnetic flowmeter.
Elekitirodi yolakwika ndi zida zomangira, kusakhutira kwa chitoliro, kutalika kosakwanira kwa chitoliro chowongoka, komanso kusanja bwino pakuyika kwa mainchesi ang'onoang'ono nthawi zambiri ndizinthu zazikulu zomwe zimapangitsa kuti electromagnetic flowmeter kulephera kugwira ntchito moyenera.
