Ngabe i-caustic soda icwengeka kanjani "?

I-Caustic Soda, eyaziwa ngamakhemikhali njenge-sodium hydroxide (NAOH), imvamisa ibizwa ngokuthi yi-alle, i-caustic aldrali, noma i-sodium hydrate. Kuza ngamafomu amabili aphambili: aqinile noketshezi. I-Solid Couustic Soda iyinto emhlophe, esobala ye-crystalline, imvamisa eFlake noma i-granular form. I-Liquid Couustic Soda yisisombululo esinamanzi sikaNaoh.

I-Caustic Soda iyinto ebalulekile yamakhemikhali esetshenziswayo esetshenziswa kabanzi kulo lonke elalwaneni amakhemikhali, i-pulp nephepha ukukhiqizwa, izindwangu nokudaya, i-metallurgy, insipho kanye nokukhiqizwa kokukhiqizwa kwempahla, kanye nezimboni zokuvikela imvelo.

1. Isingeniso ku-Caustic Soda

1.1 Umqondo we-caustic soda

I-Caustic Soda inefomula yamakhemikhali Naoh. Kubonakala ngo:
1
2. I-solubity ephezulu emanzini: ihlakaze kalula emanzini ngokukhululwa okukhulu kokushisa, yakha isixazululo se-alkaline. Kuyancibilika futhi e-ethanol ne-glycerin.
I-3. I-Deliifunayo: I-Solic Couustic Soda idonsa kalula umswakama kanye nekhabhoni diokdide emoyeni, okuholela ekuguqulweni kwayo.
4. I-Hygroscopicity: I-Naoh eqinile i-hygroscopic kakhulu futhi, lapho ivezwa umoya, ithola umswakama ize ichitheke ngokuphelele kwikhambi eliwuketshezi. I-Liquid Couustic Soda ayinayo le mpahla.

1.2 Ukuhlukaniswa kwe-caustic soda
• Ngefomu lomzimba:
• I-CAUCIC Soda eqinile: Flake Caustic Soda, i-granular caustic soda, kanye ne-caustic-packed caustic soda eqinile ye-caustic.
• I-Liquid Couustic Soda: Ukugxila okujwayelekile kufaka ama-30%, ama-32%, ama-42%, ama-45%, nama-50%, anama-50% futhi angama-50% abe evame kakhulu emakethe.
• Ukwabelana Kwezimakethe:
• Ama-akhawunti e-Liquid Couustic Soda angu-80% wokukhiqizwa okuphelele.
• Isoda eqinile ye-caustic, ikakhulukazi i-flake caustic soda, yenza cishe i-14%.

1.3 Izicelo ze-caustic soda
1. I-Metallurgy: Iguqula izingxenye eziwusizo ze-Ores zibe ngosawoti we-sodium solium, okuvumela ukususwa kokungcola kokungcola.
2. Indwangu yendwangu nokudaya: isetshenziswa njenge-ejenti ethambisayo, umenzeli wokuhlanza, kanye ne-ejenti elungisa ukuthuthukisa ukuthungwa kwendwangu kanye nokumuncwa okwedayi.
I-3. Imboni yamakhemikhali: impahla ebalulekile ekhiqizwayo ePolycarbonate, ama-polyments asezingeni eliphezulu, ama-epoxy resins, ama-phosphates kanye nosawoti we-sodium ahlukahlukene.
I-4. I-pulp nephepha: isusa i-lignin kanye nokunye ukungcola kusuka ku-soni pulp, ngcono ikhwalithi yephepha.

1.4 Ukupakishwa, Isitoreji, kanye Nezokuhamba
• Ukupakisha: Kuhlukaniswe njenge-Class 8 Into Ewonke Ekhohlakele ngaphansi kwe-GB 13690-92 futhi kufanele ithwale "impahla ekholisayo" nge-GB190-2009.
• Ukuhamba:
• I-Liquid Caustic Soda: Ihanjiswa ngamathangi ensimbi yekhabhoni; Ukuhlanzeka okuphezulu noma> 45% izixazululo zokuhlushwa zidinga amathangi wensimbi ye-nickel alloy.
• I-Solid Couustic Soda: Ngokuvamile igcwele ezikhwameni ezilukiwe ze-25kg kathathu noma izigubhu.

2. Izindlela Zokukhiqiza Izimboni

I-Caustic Soda ikhiqizwa ngokuyinhloko ngezindlela ezimbili:
1. Indlela yokuqalisa
2. Indlela ye-electrolytic: I-electrolysis yekhambi eligcwele i-sodium chloride (i-NACL) ithela i-caustic soda, nge-chlorine gesi (CL₂) ne-hydrogen gas (H₂) njengemikhiqizo edlula ngayo.
• Indlela ye-Ion Exchange Membrane iyinqubo evame kakhulu ye-electrolytic.

Isilinganiso sokukhiqiza:
• I-1 Ton kaNaoh ikhiqiza amathani angama-0.886 e-chlorine igesi namathani angama-0.025 e-hydrogen gas.

I-Caustic Soda ingamakhemikhali abucayi wezimboni anezicelo ezibanzi ezihamba ngezimboni eziningi futhi adlala indima ebalulekile ezinhlanganweni ezahlukahlukene zokukhiqiza.
