Yaiwisi zamkati lili appreciable kuchuluka kwa lignin ndi ma discoloration ena, ayenera bleached Yaiwisi zamkati lili appreciable kuchuluka kwa lignin ndi ma discoloration, ayenera bleached kubala kuwala akuda kapena woyera mapepala amakonda mankhwala ambiri.Ulusiwu umapangidwanso kuti usungunuke ndikusungunula lignin yowonjezera kuchokera ku cellulose kudzera mu chlorination ndi okosijeni.Sodium Hydrooxide, alkali yolimba imagwiritsidwa ntchito pochotsa lignin yosungunuka kuchokera ku ulusi pamwamba.Mankhwala opangidwa ndi ma bleaching ma pulps amawotchi amawononga zodetsa za utoto koma amasiya lignin ndi cellulosic zida zonse, monga sodium bisulfite, sodium kapena zinki hydrosulfite, calcium kapena sodium hypochlorite, hydrogen kapena sodium peroxide, ndi Njira ya Sulfur Dioxide-Borol.
Pofuna kuonetsetsa kuti kuyera kwa pepala ndi kofanana, zowonjezera zowonjezera, dispersants ndi bleaching agents ziyenera kuwonjezeredwa.Monga momwe zimagwiritsidwira ntchito zowonjezera m'makampani azakudya, zowonjezerazi zimakhala ndi kayendedwe kakang'ono ndipo zimakhala zowonongeka kwambiri.
Ubwino:
?Ikhoza kukhazikitsidwa ndi zipangizo zosiyanasiyana kuti zigwirizane ndi zosowa za ndondomeko
?M'mimba mwake mopanda kutsika kwamphamvu kudutsa mita
?Miyezo yokhazikika, yolondola yomwe imayimira kuyenda kwenikweni.
Chovuta:
?Kuthamanga kumakhala kochepa, ndipo chizindikiro chotuluka chidzasinthasintha kwambiri.
?Njira yowononga kwambiri idzakhudza moyo wautumiki
Lining: Ambiri aiwo amasankha PTFE lining ndi PFA lining.
Electrode: Ta/Pt osankhidwa malinga ndi katundu wamadzimadzi osiyanasiyana
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.
