Njira zowonongera kunja kwa sodium hydroxide

Sodium hydroxide, amatchedwanso caustic soda ndi caustic soda, mankhwala ndi NaOH, ndi mtundu wa alkali wamphamvu wokhala ndi kuwonongeka kwakukulu, kofiyira koyera kapena tinthu tating'onoting'ono, titha kusungunuka m'madzi kuti apange yankho lamchere, amathanso kusungunuka mu methanol ndi Mowa. Sodium hydroxide ili ndi mchere wambiri, womwe umatha kuyamwa nthunzi yamadzi mumlengalenga, komanso kuyamwa mpweya wa asidi monga carbon dioxide ndi sulfure dioxide.

Chilengedwe

Sodium hydroxide imawononga kwambiri, yolimba kapena yankho lake limatha kuwotcha khungu, lomwe lingayambitse kuvulaza kosatha (monga chilonda) kwa iwo opanda njira zodzitetezera. Ngati sodium hydroxide imawonekera m'maso mwachindunji, yayikuluyo imatha kupangitsa khungu. Njira zodzitetezera, monga magolovesi a labala, zovala zoteteza ndi magalasi, zitha kuchepetsa kwambiri mwayi wokhudzana ndi sodium hydroxide

Cholinga

Sodium hydroxide amagwiritsidwa ntchito kwambiri. Amagwiritsidwa ntchito popanga mapepala, sopo, utoto, rayon, kuyenga mafuta, kumaliza kwa thonje, kuyeretsa kwa phula la malasha, kukonza chakudya, kukonza nkhuni ndi makina amakina.

Sodium hydroxide imagwiritsidwa ntchito kwambiri pachuma, magawo ambiri amakampani amafunikira sodium hydroxide. Magawo omwe amagwiritsa ntchito sodium hydroxide ambiri ndimapangidwe amakankhwala, otsatiridwa ndi kupanga papepala, kuyungunuka kwa aluminium, kuyenga kwa tungsten, rayon, thonje lochita kupanga komanso kupanga sopo. Kuphatikiza apo, pakupanga utoto, mapulasitiki, mankhwala ndi othandizira pakati, kupangidwanso kwa mphira wakale, electrolysis yachitsulo ya sodium ndi madzi, komanso kupanga mchere wambiri, soda wambiri amagwiritsidwanso ntchito popanga Nthawi yomweyo, sodium hydroxide ndi imodzi mwazinthu zofunikira popangira polycarbonate, polima woyamwa kwambiri, zeolite, epoxy resin, sodium phosphate, sodium sulfite ndi sodium yambiri mchere.

Zofunika Kuyenda Padziko Lapansi

Choyamba, gwero silingathe kunyamulidwa ndi zitini za aluminiyamu kapena zinc, chifukwa sodium hydroxide ndiyokhazikika, ndipo yankho lake limayenderana ndi aluminium ndi zinc kupanga hydrogen gasi, sodium metaaluminate kapena metazincate ya sodium

Chachiwiri, sindikiza ndi kudzaza! Chifukwa ngati kuli mpweya, sodium hydroxide idzawonongeka! Sodium carbonate ndi madzi amapangidwa

Chachitatu, kuthira nayitrogeni, oxygen ndi mpweya wina woteteza mu thanki, konzekerani mpweya momwe mungathere, kenako onjezani sodium hydroxide solution, pang'onopang'ono mutulutse mpweya woteteza, ndikusindikiza mayendedwe.

Kusamalitsa Kwa Sodium Hydroxide Export Ndi Nyanja

Zikalata zogulitsa kunja kwa sodium hydroxide panyanja

1. Kuphika
Mphamvu yosungitsa maloya: kuphatikiza pazomatumizira ndi zomwe zimatumizidwa, chofunikira kwambiri ndikufotokozera momveka bwino za kulemera konse, kulemera kwa ukonde, mawonekedwe olongedza ndi kulongedza kwamkati kwa chidutswa chimodzi
(zindikirani kuti kusungitsa katundu wowopsa kwa katundu kunja kuyenera kupangidwa kutatsala masiku khumi. Zambiri zowerengera katundu zowopsa ziyenera kukhala zolondola ndipo sizingasinthidwe.)

2.MSDS mu Chingerezi
MSDS (omwe ali ndi zombo azingoyang'ana kwambiri zinthu zakuthupi ndi zamankhwala komanso zoyendera, zomwe zimatsimikizira omwe ali ndi zombo. Adzadziwa mwachilengedwe momwe angagwiritsire ntchito mayendedwe)
Zindikirani: sodium hydroxide ndi ya m'gulu 8 la zinthu zowopsa, UN 1823, gulu II fomu yolengeza satifiketi yoopsa

Ndi mphamvu ya loya ndi MSDS, mutha kusungitsa malo oopsa. Nthawi zambiri masiku awiri ogwira ntchito amatha kugawidwa.

Satifiketi phukusi 3.Dangerous
(imaphatikizira pepala la magwiridwe antchito ndi satifiketi yogwiritsira ntchito. Tsamba la magwiridwe antchito ndilosavuta ndipo limatha kuperekedwa ndi opanga omwe amatha kupanga phukusi pafupipafupi. Komabe, satifiketi yogwiritsira ntchito ndiyovuta kwambiri, chifukwa chake iyenera kupita ku Kuyendera kwa Zogulitsa kwanuko Bureau wa fakitare kutsatira ndi chizindikiritso cha IMI ndi pepala logwirira ntchito.)

Chidziwitso cha katundu wa 4
Chotsatira ndikulengeza katundu wowopsa. Malinga ndi zofunikira zamakampani osiyanasiyana otumiza ndi omwe akutumiza, zida zodzitumizira zitha kutumizidwa malinga ndi tsiku lomaliza asanalengeze. Kulengezedwa kwa katundu wowopsa makamaka ndikuwunika phukusili, chifukwa chikalata chofunikira kwambiri ndi satifiketi yoopsa yazinthu.
Zida zolengeza zowopsa: satifiketi yoyambirira yaphukusi lowopsa, English MSDS, mndandanda wazolongedza, satifiketi yolongedza, mphamvu yakulengeza

5. Kukonzekera mayendedwe ndi kulongedza ndi gawo lofunikira
Izi zitha kugawidwa m'magulu awiri ogwira ntchito: kutsitsa kosungira katundu ndi chipata cha fakitale Point Trailer
Ngati yadzaza munyumba yosungiramo katundu, muyenera kupanga chiphaso cholowera posungira kuti mutsimikizire nthawi yobweretsera yosungira ndi kasitomala
Ngati kalavani yachitseko cha fakita ikugwiritsidwa ntchito, ikuyenera kunyamulidwa ndi zombo zomwe zili ndi ziyeneretso za katundu wowopsa. Woyendetsa dalaivala ayenera kukhala woyendetsa wakale wazolowera wagalimoto yazinthu zowopsa, yemwe amatha kumaliza kutsitsa mosamala komanso munthawi yake.

6. Nenani za miyambo
Kuphatikiza pa chidziwitso cha chizolowezi chazikhalidwe, ziyenera kudziwikanso kuti sodium hydroxide ndi ya katunduyo poyang'aniridwa mwalamulo, ndipo kuyang'aniridwa kwa zinthu kuyenera kuperekedwanso kutumiza panyanja.

7.Bill wonyamula katundu
Sitimayo ikanyamuka, tengani katundu woti mukalipire, mutsimikizire ndi amene mwapatsayo ngati angapereke chikalata choyambitsira katundu kapena kutumiza telegraphic, ndikukonzekera chilolezo chobweza ndi kutumizira sitimayo ikafika padoko lopita.
Sodium hydroxide ndi amtundu wa 8 wazinthu zowopsa, zomwe zimatha kutumizidwa ndi LCL. Komabe, ziyenera kudziwika kuti sizingasakanizidwe ndi mitundu 4 ya zinthu zowopsa kapena zinthu za acidic, ndipo ziyenera kutsatira mosamalitsa zofunikira zakubisalira ndi kudzipatula kwa katundu wowopsa ndi LCL.
