Kev Tiv Thaiv Corrosion thiab Tswj hauv Sodium Hydroxide Solution Loading thiab Unloading -
Kev xaiv cov khoom siv thiab kev ua haujlwm Specifications tshwj xeeb Loading Arms
Sodium hydroxide tov (caustic soda tov), uas yog ib qho tseem ceeb ntawm cov khoom siv raw, yog siv dav hauv papermaking, luam ntawv thiab dyeing, tshuaj synthesis thiab lwm yam. Qhov kev daws teeb meem no muaj cov yam ntxwv ntawm kev muaj zog corrosion, siab viscosity, thiab crystallization yooj yim, uas tso siab rau cov kev xav tau siab heev ntawm kev tiv thaiv corrosion thiab kev ruaj ntseg ntawm cov khoom thaum lub sij hawm thauj khoom thiab unloading. Qhov tshwj xeeb sodium hydroxide tov Loading Arm zoo daws qhov teeb meem ntawm kev tiv thaiv corrosion thiab tswj los ntawm kev xaiv cov khoom siv scientific thiab cov qauv tsim qauv, kom ntseeg tau tias muaj kev nyab xeeb thiab muaj txiaj ntsig kev thauj khoom thiab kev thauj khoom.
Material selection is the core of the sodium hydroxide solution loading arm to resist corrosion. According to the different concentration and temperature of the sodium hydroxide solution, the material selection needs to be accurately matched. For low-concentration (≤30%) sodium hydroxide solution at room temperature, a loading arm made of ordinary carbon steel can be selected, which has low cost and can meet the basic corrosion resistance requirements; for high-concentration (>30%) or high-temperature (>60 degree) sodium hydroxide tov, vim muaj kev txhim kho corrosion zoo heev, yuav tsum muaj cov khoom thauj khoom los ntawm stainless hlau (304 lossis 316L) lossis roj hmab- cov khoom siv lined. Cov roj hmab- cov khoom siv kab hauv phab ntsa ntawm cov raj xa dej nrog cov roj hmab nitrile lossis fluororubber, thiab siv cov alkali tiv thaiv zoo ntawm cov roj hmab kom zoo cais cov tshuaj sodium hydroxide, thiab tseem muaj kev cuam tshuam zoo.
Kev ua kom zoo ntawm cov qauv tsim muab kev lees paub rau qhov smoothness ntawm kev thauj khoom thiab tshem tawm cov haujlwm. Sodium hydroxide tov muaj viscosity siab, thiab nws yooj yim rau crystallize tshwj xeeb tshaj yog nyob rau hauv qis -kub ib puag ncig. Yog li ntawd, txoj kab uas hla ntawm lub caj npab loading feem ntau yog loj dua li ntawm cov khoom siv ua kua zoo tib yam, nrog rau txoj kab uas hla ntawm DN100-DN200 kom txo tau kev thauj mus los. Nyob rau tib lub sijhawm, lub cev caj npab tau txais ntau qhov kev sib koom ua ke, feem ntau yog nruab nrog 3-5 cov pob qij txha, kom ntseeg tau tias lub viav vias ntawm caj npab lub cev nyob rau hauv kab rov tav thiab ntsug, uas yog yooj yim rau docking nrog txawv specifications ntawm lub tank tsheb thiab cia tso tsheb hlau luam. Ntxiv rau,
