Kugwiritsa ntchito
Oxalic acidVesi yothetsera vuto ndi oxalic acid ndi oganiza bwino ndipo amagwiritsidwa ntchito kwambiri m'minda monga kusanthula kwa mankhwala, kupanga mafakitale, komanso kufufuza kwasayansi. Njira zazikulu zofunsira ndizotere:
Kusanthula kwa mankhwala ndi kutsimikiza
- Acid - Tsamba la Base: Oxalic Acid ndi acid a dibasic ofooka a asidi omwe amatha kuchitika chifukwa cha zimbudzi. Itha kugwiritsidwa ntchito ngati njira yothetsera vuto la asidi kuti mudziwe kuchuluka kwa osadziwika - okhazikika alkalinel alkaline. Mwachitsanzo, pofalitsa yankho la sodium hydroxide ndi oxalic acid njira yothetsera vuto la sodium la sodium limatha kuwerengedwa muyeso pomaliza - kuloza kuthiratu.
- Cholembera cha Redox: Gawo la kaboni la oxalic acid lili ndi vuto la +3, kuwonetsa kusintha komanso kukhala ndi zinthu zochulukirapo zokongoletsera zomwe zimachitika. Mu acidic sing'anga sing'anga, sodium oxalate amatha kukhala oxidid permanganate. Pogwiritsa ntchito izi, oxalic acid njira yothetsera kusintha njira yolondola ya potaziyamu permanganate yankho.
Kuwongolera kwa mafakitale
- Chithandizo cha Zitsulo: Pachithandizo chamankhwala chothandizira zitsulo monga aluminiyamu, oxalic anic amatha kugwiritsidwa ntchito pokonza ndi kuyeretsa. Pogwiritsa ntchito oxalic acid moyenerera yankho, yankho lomwe limagwira ntchito limatha kulamuliridwa bwino kuti zitsimikizire kusinthana ndi kukhazikika kwa chitsulo, motero kumasintha mtundu. Mwachitsanzo, powongolera kuchuluka kwa oxalic acid muyezo munthawi inayake, mankhwala a aluminium amatha kukhazikika kuti apeze ma yunifolomu komanso mawonekedwe okongola.
- Makampani Ogulitsa Mafuta: The Oxalic acid njira yothetsera kusintha kwa acidity ndi kapangidwe ka magetsi osankha, ndikuonetsetsa kuti wosanjikiza. Kuwongolera molondola oxalic acid kumathandizira modekha, kuwongolera, ndikukana kuchuluka kwa malo a elekitikilo, kuwonetsetsa kuti zinthu za eperiting'ono pazithunzi zimathandizira kuti malonda azikhala ndi miyezo yapamwamba.
Kutumiza ndi kutumiza
25kg / Drum kapena monga zofunikira zamakasitomala.
Kutumiza: Mitundu 6 ya katundu wowopsa ndipo amatha kupulumutsa pa nyanja.
Pitilizani ndikusunga
Moyo wa alumali: Mwezi 24 kuyambira tsiku lopanga mu phukusi lokhazikika losagwirizana ndi dzuwa louma, madzi.
Chosokoneza chosungira, kuyanika kwa kutentha kochepa, kupatulidwa ndi oxidants, ma acid.
