Sodium Hydroxide, inowanzozivikanwa seCousic Soda, moto Svutugadzike, uye Svutugadzike wechigaro, iShonali yakanyanya kuora muchimiro chehupfumi, granules, kana zvidhinha. Iyo inonyura mumvura (inoburitsa kupisa kana ikanyungudika mumvura) uye inoumba iyo alkaline solution. Iyo ndeye maune uye inogona kutora nyore nyore mvura mitsipa (mirequecence) uye kabhoni dioxide (kudzikira) mumhepo. Hydrochloric acid inogona kuwedzerwa kuti utarise kana yakashatiswa. Inonyudza mumvura, ethanol, uye glycrol, asi kusakwana muaccountone uye ether. Iyo yakachena chigadzirwa inguva isina ruvara uye yakajeka crystal. Density 2.13G / cm3. Inline Pfungwa 318 ℃. Boling point 1388 ℃. Zvigadzirwa zveindasitiri zvine huwandu hushoma hwe sodium chloride uye sodium carbonate, iyo ine chena opaque makristasi. Ngatitaurei nezvezvinoshanda zvinoshanda zveSodium hydroxide muSimbi Specurance Maitiro ekurapa.
1 Kana iko kusungwa kwesodium hydroxide kuderera uye iyo pH isingasviki 100.5, sodium Stearate ichava hydrolyzed uye yekubvisa mafuta ichaderedzwa; Kana kushushikana kwakanyanya, iyo solubility yeSodium Stearate uye Surfactant ichadzikiswa, zvichikonzera mumvura isina kuriririsa uye hydrogen oxidation. Iyo sodium dosage kazhinji haina kupfuura 100g / l. Sodium Hydroxide inoshandiswa zvakanyanya muzvikamu zvesimbi, senge simbi dzakasiyana-siyana, titanium aiti, enlc., etc. Nekudaro, sodium hydroxide haifanirwe kushandiswa kuti ishandiswe ackrease-inonyungudika simbi zvikamu senge aluminium ne zinc. Alkaline degreasing yezvikamu zvepurasitiki zvakakodzera Abs, polysulfone, yakagadziridzwa polystyrene, etc.
2. Metal etching application ①. Mukubatwa kweAluminium Alloy pamberi oxidation, huwandu hukuru hwesodium hydroxide inoshandiswa kune alkali etching. Iyi nzira ndiyo yakajairwa kurapwa nzira pamberi paAluminium Alloy oxidation. Mari yakakura yeSodium Hydroxide inoshandiswawo kune aluminium Alloy Tembiricha. ②. Sodium Hydroxide is yakakosha etching zvinhu mumakemikari etching maitiro ealuminium uye alloys. Iyo zvakare nzira yakajairika etching nhasi. Muchiitiko cheEtching of aluminium uye alloys, zvirimo zveSodium Hydroxide zvinowanzotongwa pa100 ~ 200g / l. , uye sekusangana kwesodium hydroxide inowedzera, kumhanya kwekukurumidza kunowedzera. Nekudaro, kana kusangana kwakanyanya, kuchawedzera mutengo. Iyo etching mhando yezvimwe zvishandiso zvealuminium zvinokanganisa. Maitiro acho ari anotevera ai + naoh + h2o = naao2 + h2 ↑
3. MuElectroplating uye Chemical Exclating Zvikumbiro, huwandu hwakawanda hweSodium hydroxide hunoshandiswa muAlkaline tin plating neAlkaline zinc plating. Kunyanya muAlkaline zinc plating, huwandu hwakakwana hwe sodium hydroxide ndiyo mamiriro ekutanga kuchengetedza mhinduro kugadzikana; Mune zvemagetsi plating iyo inoshandiswa kune pH kugadzirisa kweiyo yemagetsi yemhangura yemhangura; Inoshandiswa kugadzirira kweZinc Emmerson Solution isati aluminium Alloy Eley Electroless plating / eledeclating, etc. ①. Application muCyanide zinc plating. Sodium hydroxide ndechimwezve chakaoma mumiririri mukugeza kwekutanga. Izvo zvinomedza ne zinc ions kuumba zincate zincate ions, iyo inoita kuti iyo yekugezesa yekuisa yakagadzikana uye inovandudza iyo yekugezesa yekugeza ekutanga. Naizvozvo, iyo cathode ikozvino kushanda kwayo uye kugona kupararira kwemhinduro yekutanga inogadziriswa. Kana sodium hydroxide yezvinyorwa yakakwira, iyo anode inopera nekukurumidza, ichikonzera zvirimo mumhinduro yekuisa mukuwedzera kwekuwedzera uye kuunganidza kuve kwakaoma. Kana iyo sodium hydroxide yakanyanya kuderera, iyo yekuita kwemhinduro yekutanga kune murombo, kushanda kwazvino kunoderera, uye kuunganidza kuchave kwakaoma. Mumhinduro yekutanga isina sodium hydroxide, iyo cathode yekubudirira yakaderera kwazvo. Sezvo kusangana kwesodium hydroxide inowedzera, iyo cathode yekubudirira inowedzera zvishoma nezvishoma. Kana kusungwa kwesodium hydroxide inosvika kune imwe mari (yakadai se 80g / l), iyo cathode inoshanda yakanyanya kukosha uye inosara zvakanyanya nguva dzose. ②. Chikumbiro mu zincate electroplating: Sodium hydroxide is a akaoma mumubatanidzwa uye munyu waitaura. Kuwedzeredza kushoma kwesodium hydroxide kunogona kuita kuti ifunge kuti yakagadzikana zvakanyanya uye ine nhungamiro iri nani, iyo inobatsira kuvandudza kugona kwekupararira kwemhinduro yekutanga. , uye bvumira iyo anode kuti azungunuke kazhinji. Misa chiyero cheZinc oxide kuSodium Hydroxide muZincate Pleting Solature Kugadzirisa nezve 1: (10 ~ 14), neyakaderera muganho wekurembera uye muganho wepamusoro wembiya. Kana sodium hydroxide yezvinyorwa zvakanyanyisa, iyo Anode inokwira nekukurumidza, kusangana kweZinc ions mune yekugezesa yekugezesa yakanyanya kukwirira, uye crystallization yekubatanidza haina kunaka. Kana zvirizvo zvakanyanyisa kuderera, kubatana kweiyo yekugezesa yekugezesa yakaderedzwa, uye zinc hydroxide precipitation inogadzirwa zviri nyore, iyo inokanganisa kunaka kwekucheka. ③. Application muAlkaline tin plating. MuAlkaline tin plating, basa guru reSodium hydroxide riri kuumba rakagadzikana pamwe neTin munyu, kuvandudza maitiro, uye kugonesa kupaza kwakajairika kweanode. Sezvo kusangana kwesodium hydroxide inowedzera, polarization inova yakasimba uye kugona kwekuparadzira kuwedzera, asi kushanda kwazvino kunodzikira. Kana iyo sodium hydroxide yakanyanya kukwirira, zvakaoma kune iyo anode kuchengetedza mamiriro ezvipangamwi uye akanyungudika tin, zvichikonzera kusarongeka kubata. Naizvozvo, kudzora kusungwa kwesodium hydroxide yakanyanya kukosha kupfuura kudzora iyo tin yemunyu wemunyu. Kazhinji sodium hydroxide inodzorwa pa7 ~ 15g / l, uye kana potasasium hydroxide inoshandiswa, inodzorwa pa10 ~ 20g / l. MuAlkaline Vakasarudzika Mhosva Mhosva Pasi pemamwe mamiriro ezvinhu, kuwedzera kusunganidzwa kwesodium hydroxide inogona kuwedzera nekumhanya kwesodium hydroxide Sodium hydroxide inowanzoshandiswa zvakanyanya mumhando yesimbi. Kusunganidzwa kwesodium hydroxide zvakananga zvinobata zvinyoronyoro zvekumhanya kwesimbi. Yakakwira-carbon simbi ine nekukurumidza oxidation kumhanya uye yakaderera constrenration (550 ~ 650G / l) inogona kushandiswa. Low-carbon Steel oxidation iyo yekumhanyisa inononoka uye yakakwira misheni (600 ~ 00g / l) inogona kushandiswa. Kana iko kusungwa kwesodium hydroxide yakakwira, iyo yefoni yemhando yakakwira, asi iyo firimu yakasununguka uye ine guruva, uye rutsvuku, uye rakatsvuka, uye rutsvuku, Kana kusungwa kwesodium hydroxide inopfuura 1100g / l, iyo magineti yesimbi erodelved uye haigone kuumba firimu. Kusungwa kwesodium hydroxide kana yakaderera, iyo yehofisi yemhando ichave yakaonda uye pamusoro ichave ichipenya, uye kuita kwekudzivirira kuchave murombo.
