Ana kula da yadudduka na lilin tare da maida hankali sodium hydroxide (caustic soda) bayani don inganta abubuwan fiber.Filayen da mutum ya yi kamar su rayon, rayon, rayon, da dai sauransu, galibin filayen viscose ne.An yi su ne da cellulose (irin su ɓangaren litattafan almara), sodium hydroxide, da carbon disulfide (CS2) a matsayin kayan da za a yi ruwa na viscose, wanda aka fesa, wanda aka yi ta hanyar condensation.
2).Viscose fiber
Da farko, yi amfani da 18-20% caustic soda bayani don impregnate da cellulose yin shi a cikin alkali cellulose, sa'an nan bushe da murkushe alkali cellulose, ƙara carbon disulfide, kuma a karshe narkar da sulfonate da dilute lye don samun viscose .Bayan tacewa da vacuuming (cire kumfa mai iska), ana iya amfani dashi don jujjuya.
4. Yin takarda
Abubuwan da ake amfani da su don yin takarda sune tsire-tsire na itace ko ciyawa, wanda ya ƙunshi adadi mai yawa na wadanda ba cellulose (lignin, danko, da dai sauransu) ban da cellulose.Ana amfani da sodium hydroxide don lalata, kuma lokacin da aka cire lignin a cikin itace kawai za'a iya samun fibers.Abubuwan da ba na cellulose ba za a iya narkar da su kuma a raba su ta hanyar ƙara dilute sodium hydroxide bayani, don haka ana iya samun ɓangaren litattafan almara tare da cellulose a matsayin babban sashi.
5. Inganta ƙasa tare da lemun tsami.
A cikin ƙasa, yanayin yanayi na ma'adanai na iya haifar da acid saboda samuwar kwayoyin acid yayin da kwayoyin halitta suka lalace.Bugu da kari, yin amfani da takin zamani irin su ammonium sulfate da ammonium chloride shi ma zai sa kasar ta zama acidic.Yin amfani da adadin lemun tsami da ya dace zai iya kawar da abubuwan acidic a cikin ƙasa, yin ƙasa da ta dace da haɓakar amfanin gona da haɓaka haifuwa na ƙwayoyin cuta.Ƙara Ca2 + a cikin ƙasa zai iya inganta coagulation na ƙasa colloid, wanda ke da tasiri ga samuwar aggregates, kuma a lokaci guda zai iya samar da calcium da ake bukata don ci gaban shuka.
6. Chemical masana'antu da sinadaran reagents.
A cikin masana'antar sinadarai, ana amfani da soda caustic don yin ƙarfe na sodium da ruwa na lantarki.Ana amfani da caustic soda ko soda ash wajen samar da salts na inorganic da yawa, musamman a shirye-shiryen wasu gishirin sodium (irin su borax, sodium silicate, sodium phosphate, sodium dichromate, sodium sulfite, da sauransu).Caustic soda ko soda ash kuma ana amfani dashi a cikin haɗin dyes, kwayoyi da tsaka-tsakin kwayoyin halitta.
7. roba, fata
1).Silica mai hazo
Na farko: yi gilashin ruwa (Na2O.mSO2) ta hanyar amsa sodium hydroxide tare da ma'adinin ma'adini (SiO2)
Na biyu: amsa gilashin ruwa tare da sulfuric acid, hydrochloric acid, da carbon dioxide don samar da farin carbon baƙar fata (silicon dioxide)
Silica da aka ambata a nan ita ce mafi kyawun ƙarfafawa don roba na halitta da roba na roba
2).Sake amfani da tsohon roba
A cikin sake yin amfani da tsohuwar roba, ana yin maganin foda na roba tare da maganin sodium hydroxide, sannan a sarrafa shi.
3).Fata
Tannery: tsarin sake yin amfani da ruwa mai sharar tannery, a gefe guda, tsakanin matakai biyu na sodium sulfide aqueous bayani jiƙa jiƙa da ƙara lemun tsami foda jika jiyya a cikin data kasance fadada tsarin, da amfani da tare nauyi yana karuwa da 0.3-0.5. % Matakin jiyya na maganin 30% sodium hydroxide yana sa fiber na fata ya faɗo gabaɗaya, ya sadu da buƙatun tsari, kuma yana haɓaka ingancin samfurin da aka kammala.
8. Karfe, electroplating
A cikin masana'antar ƙarfe, sau da yawa ya zama dole a canza sinadarai masu aiki a cikin ma'adinai zuwa salts sodium mai narkewa don cire ƙazantattun da ba za a iya narkewa ba.Sabili da haka, sau da yawa ya zama dole don ƙara soda ash (shima maɗaukaki ne), kuma wani lokacin ana amfani da soda caustic.
9.sauran bangarorin rawar
1).Akwai ayyuka guda biyu na yumbu caustic soda a cikin kera yumbu.Na farko, ana amfani da soda caustic a matsayin diluent a cikin aikin harbe-harbe na yumbu.Na biyu, saman yumbun da aka kora za a tashe shi ko kuma ya yi muni sosai.Tsaftace shi tare da maganin soda caustic A ƙarshe, sanya saman yumbu ya zama santsi.
2).A cikin masana'antar kayan aiki, ana amfani dashi azaman neutralizer acid, decolorizer da deodorizer.Ana amfani da masana'antar m azaman sitaci gelatinizer da neutralizer.Ana iya amfani da shi azaman wakili mai kwasfa, wakili mai lalata launi da wakili na deodorizing na citrus, peach, da sauransu.
