Raw pulp muaj cov txiaj ntsig zoo ntawm lignin thiab lwm yam xim, nws yuav tsum tau bleached Raw pulp muaj cov txiaj ntsig zoo ntawm lignin thiab lwm yam xim, nws yuav tsum tau bleached los tsim cov xim dawb lossis cov ntawv dawb nyiam rau ntau yam khoom. Cov fibers yog ntxiv delignified los ntawm solubilizing ntxiv lignin los ntawm cellulose los ntawm chlorination thiab oxidation. Sodium Hydroxide, alkali muaj zog yog siv los tshem tawm cov lignin yaj ntawm fibers nto. Cov tshuaj siv los ua cov tshuaj pleev xim rau cov tawv nqaij xaiv cov xim tsis huv tab sis tso cov lignin thiab cellulosic cov ntaub ntawv tsis zoo, xws li sodium bisulfite, sodium los yog zinc hydrosulfite, calcium los yog sodium hypochlorite, hydrogen los yog sodium peroxide, thiab cov txheej txheem Sulfur Dioxide-Borol.
Txhawm rau kom ntseeg tau tias cov ntawv dawb ntawm daim ntawv yog qhov sib npaug thiab zoo, cov khoom sib txawv, cov tshuaj dispersants thiab cov tshuaj bleaching yuav tsum tau ntxiv. Raws li kev siv cov additives hauv kev lag luam khoom noj khoom haus, cov additives no muaj tus nqi me me thiab muaj corrosive heev.
Qhov zoo:
? Yuav tau configured nrog ntau yam khoom siv kom phim cov txheej txheem xav tau
? Tag nrho txoj kab uas hla uas tsis muaj siab poob thoob 'meter'
? Kev ntsuas ruaj khov, raug ntsuas uas sawv cev rau qhov tseeb ntws.
Kev sib tw:
? Tus nqi ntws yog me me, thiab cov teeb liab tso zis yuav hloov pauv tau zoo heev.
? Qhov nruab nrab corrosive heev yuav cuam tshuam rau lub neej kev pabcuam
Hauv ob sab phlu: Lawv feem ntau xaiv PTFE hauv ob sab phlu thiab PFA hauv ob sab phlu.
Electrode: Ta / Pt xaiv raws li cov kua dej sib txawv
Ua tib zoo saib xyuas qhov concentricity thaum txhim kho lub me me-caliber electromagnetic flowmeter.
Cov khoom siv hluav taws xob tsis zoo thiab cov ntaub ntawv hauv ob sab phlu, tsis txaus siab ntawm cov yeeb nkab, qhov ntev tsis txaus ntawm cov yeeb nkab ncaj, thiab kev ua tsis zoo thaum lub sij hawm me me-inch installation feem ntau yog qhov tseem ceeb uas ua rau lub tshuab electromagnetic flowmeter ua haujlwm tsis zoo.
