Raw pulp ine huwandu hunoyemurika hwe lignin uye kumwe kushanduka kwemavara, inofanirwa kucheneswa Raw pulp ine huwandu hunoyemurika hwe lignin uye kumwe kushanduka kwemavara, inofanira kucheneswa kuti ibudise mapepa ane mavara akajeka kana machena anodiwa kune zvakawanda zvigadzirwa. Iwo mafiber anowedzerwazve nekunyorovesa yakawedzera lignin kubva kune cellulose kuburikidza neklorini uye oxidation. Sodium Hydroxide, alkali yakasimba inoshandiswa kubvisa iyo yakanyungudika lignin kubva kune fiber pamusoro. Makemikari anoshandiswa kuchenesa mechanical pups anosarudza kuparadza kusvibiswa kwemavara asi achisiya lignin uye cellulosic zvinhu zvisina kurongeka, senge sodium bisulfite, sodium kana zinc hydrosulfite, calcium kana sodium hypochlorite, hydrogen kana sodium peroxide, uye Sulfur Dioxide-Borol process.
Kuti uone kuti kuchena kwepepa kwakaenzana uye kwakanaka, zvakasiyana-siyana zvinowedzera, zvinoparadzanisa uye bleaching agents zvinofanira kuwedzerwa. Sekushandiswa kwezvinowedzera muindasitiri yezvekudya, izvi zvinowedzera zvine diki yekuyerera uye zvinosvibisa zvakanyanya.
Advantage:
? Inogona kugadzirwa nehuwandu hwezvinhu kuti zvienderane nemaitiro ekuda
? Yakazara dhayamita isina kudzvanywa inodonha pamamita
? Yakagadzikana, zviyero zvakarurama zvinomiririra kuyerera chaiko.
Dambudziko:
? Mwero wekuyerera idiki, uye chiratidzo chekubuda chinochinja zvakanyanya.
? Yakanyanya corrosive medium inokanganisa hupenyu hwesevhisi
Lining: Vazhinji vavo vanosarudza PTFE lining uye PFA lining.
Electrode: Ta / Pt yakasarudzwa zvinoenderana neyakasiyana yemvura zvivakwa
Teerera zvakanyanya kune concentricity paunenge uchiisa diki-caliber electromagnetic flowmeter.
Iyo electrode isiriyo uye lining material, kusagutsikana kwepombi, kusakwana kureba kwepombi yakatwasuka, uye kusarongeka panguva yekumisikidzwa kwediki-dhayamita kazhinji ndizvo zvinonyanya kukonzera kuti electromagnetic flowmeter itadze kushanda zvakajairika.
