Caustic mushaba uye kushandiswa kwayo

Caustic pasoda, rinonziwo yavaibvisa hydroxide, caustic pasoda kana caustic mishonga aizivikanwa NaOH. Gore negore, nyika ukapisa anenge 57 matani caustic pasoda. upenyu Modern pasina yavaibvisa hydroxide chipo hazvibviri, sezvo caustic pasoda kunodiwa vazhinji maindasitiri sectors.

Mushaba kugadzirwa kwayo dzakasiyana

Pari, yavaibvisa hydroxide iri zvinoberekwa electrochemical nzira mukugadzirwa rehydrogen uye kuiisa chlorine kubudikidza electrolysis uye halite mhinduro.

Caustic mushaba anogadzirwa hwakasimba uye mvura chimiro. Yakasimba iri yakasimba chena guru lamellar uye mvura - nemvura chitsvuku kana Hauoneki.

Caustic pasoda, kushanda

The chikuru matavi yavaibvisa hydroxide kudya dzinosanganisira:

• makemikari indasitiri;

• pulp nebepa indasitiri;

• wehurumende kudzivirira zvivako;

• kugadzirwa biodiesel huni;

• pakuchenesa Zvikwepa mapaipi;

• Kugadzirwa detergents uye cleaners;

• chikafu indasitiri;

• neindasitiri inogadzira mishonga.

Caustic pasoda, izvo kushanda wakakura chaizvo uye siyana, anoshandiswa mishonga sezvo anowedzera kana reagent siyana nemakemikari kuti neutralize yacho iine acid titration pamwe kwemakemikari assays mu kunoitwa kuti pagadzirwe nesimbi uye zvakafanana. D. Rizivikanwe akambozvishandisa kuuraya utachiona chloramine vagadziri kubereka, uyewo kushandisa hydroxide yavaibvisa.

Caustic mushaba kuripo pakati hwezuva nezuva tose, kunyange zvisina kudaro zvakajeka. Detergents vakagadzirira kushandisa yavaibvisa hydroxide mhinduro, hunotiba- kubvisa kuzara ari pombi.

kutakura

Caustic mushaba iri yaitakurwa mugwagwa, uyewo mvura uye njanji. Mushaba mvura vari zvifambiswe chaihwo midziyo uye dzehondo, uye rakasimba yavaibvisa hydroxide akanga bagged. Panguva chokufambisa kudzivisa mwando pamusoro payo uye nokupisa chokupfeka.

Storage mushaba

Pasherufu upenyu yavaibvisa hydroxide runobva gadzira musi gore rimwe. The hwakasimba chigadzirwa yaichengetwa muna unheated akafukidzwa dzokuchengetera, muna mumapepa muchimiro. The mvura chigadzirwa anoiswa mune namahwindo mugaba alkali nemishonga.

Zvinofanira kurangarirwa kuti caustic pasoda chinhu kungatikanganisa uye kungatikanganisa. Zvinonzi basa wechipiri yepamusoro Muvuti kirasi. Kana tichishanda etims fuma yakarumbidza nokungwarira zvakanyanyisa. Kana uchitanga yakasimba kana mvura caustic pasoda, zviri chinodiwa kufukidza meso makemikari achitevedzera-nhovo magogorosi. Maoko cover inogadziriswa rabha Magorovhosi Chipfeko kana rabha pemvura. anokosha rabha masutu kana mushonga nemishonga zvipfeko akaiswa mushonga wokuuraya raive nebutiro zvinoshandiswa kudzivirira muviri.

Sei muviri womunhu

Muzviitiko uko mucous membranes uye ganda inowana caustic pasoda, zvingaite makemikari kutsva. Kuti siya kupisa zvakakanganisa nzvimbo inokurudzirwa kuti pakarepo sukurudza pasi pemvura. Kana caustic yavaibvisa unowana paganda, zvinokosha kuti ironge simba mhinduro nevhiniga.
