Ụlọ ọrụ YANGZHOU EVERBRIGHT CHEMICAL CO. LTD.

Mbadamba ụrọ caustic bụ ụdị soda caustic, aha kemịkalụ sodium hydroxide, bụ alkali soluble, nke na-emebi emebi, enwere ike iji ya dị ka neutralizer acid, ya na onye na-ahụ maka ihe mkpuchi, onye na-ebupụta mmiri, onye na-ahụ maka mmiri ozuzo, onye na-ahụ maka agba, onye na-ahụ maka saponification, onye na-ahụ maka peeling, ncha na ihe ndị ọzọ

Na-akpakọrịta nke ukwuu.Achịkọtara ojiji a na-ejikarị mbadamba nkume caustic soda dị ka ndị a:

1, ide akwụkwọ:

Ihe eji eme akwụkwọ bụ osisi ma ọ bụ ahịhịa ahịhịa, osisi ndị a na mgbakwunye na cellulose, mana nwekwara nnukwu ego nke na-abụghị cellulose (lignin, gum, wdg).A na-eji flake alkali mee ihe maka ịkatọ, na enwere ike nweta eriri naanị site na iwepu lignin na osisi.Enwere ike ịgbaze ihe na-abụghị cellulose site n'ịgbakwunye ngwọta caustic soda ngwọta, nke mere na cellulose dị ka isi akụkụ nke pulp nwere ike ịkwado.

2, mmanụ ala a nụchara anụcha:

Mgbe ejiri sulfuric acid saa ngwaahịa mmanụ ala, a ga-eji mbadamba alkali sụọ ụfọdụ ihe acidic, wee saa ya iji nweta ngwaahịa a nụchara anụcha.

3. Akwa:

A na-eji ihe ngwọta sodium hydroxide (caustic soda) na-edozi akwa na akwa ákwà linin iji melite njirimara eriri.Ihe eji eme ihe dị ka owu artificial, wool artificial, rayon, wdg, na-abụkarị eriri viscose, a na-eme ha nke cellulose (dị ka pulp), caustic soda, carbon disulfide (CS2) dị ka akụrụngwa, nke viscose mere, site n'ịtụgharị, condensation.

4, ibipụta na agba:

owu ákwà na alkaline ngwọta ọgwụgwọ, nwere ike wepụ kpuchie na owu ákwà wax, griiz, starch na ndị ọzọ bekee, mgbe ịba ụba mercerization agba nke ákwà, nke mere na dyeing ọzọ edo.

5, ime ncha:

Akụkụ bụ isi nke ncha bụ nnu sodium nke acid fatty dị elu, nke a na-ejikarị mmanụ na mbadamba alkali eme ya dị ka akụrụngwa site na mmeghachi omume saponification.Na mgbakwunye na nnu acid fatty acid dị elu, ncha nwekwara rosin, iko mmiri, ngwa nri, akwa na ihe ndị ọzọ.N'usoro, sodium fatty acid dị elu nwere akụkụ hydrophobic na-abụghị polar (hydrocarbon Group) na akụkụ hydrophilic polar (otu carboxyl).Otu hydrophobic nwere mmetụta oleophilic.N'oge a na-asa ahụ, a na-akpali griiz na unyi na-efesa n'ime obere mmanụ mmanụ, na mgbe a na-ejikọta ya na ncha, ìgwè hydrophobic (hydrocarbon Group) nke dị elu fatty acid sodium molecules na-etinye n'ime ụmụ irighiri mmanụ, na mmanụ mmanụ bụ. ndị agha van der Waals jikọtara ọnụ.Otu hydrophilic (carboxyl group), nke na-agbaze ngwa ngwa na mmiri, na-agbatị n'èzí mmanụ mmanụ ma tinye ya n'ime mmiri.Isi ihe dị na ncha bụ NaOH, mana NaOH abụghị ncha.Ngwọta mmiri ya na-abụ mmanụ griiz na enwere ike iji ya dị ka ncha.Ncha bụ emulsifier.Ụkpụrụ bụ mmeghachi omume saponification CH3CO0CH2CH3+NaOH=CH3COONa+CH3CH2OH, na CH3COONa bụ ihe na-arụ ọrụ na ncha.

6, ụlọ ọrụ kemịkalụ:

mee metal sodium, mmiri electrolytic ga-eji mbadamba nkume alkali.Mmepụta nke ọtụtụ nnu inorganic, karịsịa nkwadebe nke ụfọdụ nnu sodium (dị ka borax, sodium silicate, sodium phosphate, sodium dichromate, sodium sulfite, wdg) na-eji na mbadamba alkali.A na-ejikwa ya na njikọ nke agba, ọgwụ na organic intermediates.

7, ụlọ ọrụ metallurgical:

mgbe mgbe ịgbanwe ọrụ akụrụngwa nke ore n'ime soluble sodium nnu, iji wepụ insoluble adịghị, ya mere, mgbe mkpa ka ịgbakwunye alkali mbadamba.Dịka ọmụmaatụ, na usoro mgbaze nke aluminom, a na-eji nkwadebe nke cryolite na ọgwụgwọ bauxite.

8, iji wayo na-emezi ala:

n'ime ala, n'ihi na ihe ndị na-emepụta ihe na-emepụta ihe na-emepụta ihe na-emepụta ihe na-emepụta acid, ihu igwe nke mineral nwekwara ike ịmepụta ihe acidic.Na mgbakwunye, iji fatịlaịza inorganic dị ka ammonium sulfate, ammonium chloride, wdg, ga-emekwa ka ala dị acidic.Itinye lime kwesịrị ekwesị nwere ike imebi acid dị n'ime ala, mee ka ala dị mma maka uto ihe ọkụkụ, ma kwalite mgbasa nke microorganisms.Mgbe mmụba nke Ca2 + n'ime ala, ọ nwere ike ịkwalite condensation nke ala colloid, nke na-eme ka e nwee nchịkọta nchịkọta, ma n'otu oge ahụ, ọ nwere ike ịnye calcin achọrọ maka uto osisi.

9. Alumina mmepụta:

NaOH ngwọta na-ekpo ọkụ ka igbari alumina na bauxite ma nweta sodium aluminomrie ngwọta.Mgbe ihe ngwọta ahụ kewapụrụ na ihe fọdụrụ (ụrọ na-acha uhie uhie), a na-ebelata okpomọkụ, a na-agbakwunye aluminum hydroxide dị ka mkpụrụ kristal, mgbe ogologo oge na-akpali akpali, sodium aluminate na-emebi n'ime aluminum hydroxide, na-asacha, na calcined na 950 ~ 1200 ℃. , a na-enweta oxide aluminom emechara.A na-akpọ ihe ngwọta mgbe mmiri ozuzo nke aluminum hydroxide gasịrị, a na-akpọ nne mmanya, nke a na-ekpochapụ ma tinye uche ma megharịa ya.N'ihi usoro kristal dị iche iche nke diaspore, diaspore na diaspore, solubility ha na ngwọta soda caustic dị nnọọ iche, n'ihi ya, ọ dị mkpa ịnye ọnọdụ mgbasa ozi dị iche iche, karịsịa okpomọkụ mgbasa ozi dị iche iche.The diaspore ụdị bauxite nwere ike agbaze na 125 ~ 140C, na diaspore ụdị bauxite nwere ike etisasịwo na 240 ~ 260 ℃ na mgbakwunye na nke wayo (3 ~ 7%).
