Ma'anar sinadarai na lambar tushe
Matsakaicin adadin man inji (wanda aka gajarta TBN a cikin adabin Turanci) ƙima ce da ke nuna adadin potassium hydroxides a cikin gram ɗaya na man inji. Naúrar ma'auni shine mgKOH/g.
Kamar yadda ka sani, alkali wani nau'i ne na kishiyar acid. Yawancin acid, ba tare da la'akari da abubuwan sinadarai da ke samar da su ba, ana yin su ne lokacin da suke hulɗa da alkalis. Wato sun rasa ikon ba da gudummawar cation na hydrogen kuma an canza su zuwa mahadi masu ƙarancin aiki.
Potassium hydroxide yana daya daga cikin mafi karfi acid neutralizing Properties. A lokaci guda, maganin KOH yana da ƙarfi tsagawa, narkar da kayan wankewa. Wannan fili, alal misali, ana amfani dashi ko'ina wajen kera abubuwan da suka haɗa da kayan wanka na masana'antu. Don haka, ga mai mota, lokacin da ake ƙididdige lambar tushe, potassium hydroxide ne wanda aka ɗauka azaman ɓangaren tushe.
Ƙimar da ta dace
Man injin yana aiki a cikin mawuyacin yanayi. Matsa lamba, high yanayin zafi, man fetur shiga ta cikin zobba, zafi gas da soot - duk wannan take kaiwa zuwa makawa sinadaran canje-canje na duka tushe da ƙari aka gyara na mai.
A ƙarƙashin rinjayar yanayin zafi mai zafi da kuma kasancewar iskar oxygen, man inji yana da iskar oxygen. Ko da yake tushen abun da ke ciki, musamman roba mota mai, yana da high sinadaran kwanciyar hankali, oxides babu makawa samu a high yanayin zafi.
Me ke damun oxides? Gabaɗaya, oxidation na man inji shine ƙonawa. Bayan haka, tsarin konewa da kansa shine, daga ra'ayi na sinadarai, halayen oxidation tare da sakin zafi. Kuma samfurori na irin wannan amsa, wato, oxides, a mafi yawan lokuta, ballast marar amfani ne na tsaka-tsakin sinadarai ko marasa aiki.
Don taƙaitaccen bayanin jimlar yawancin waɗannan oxides, akwai ma wani lokaci na musamman - sludge. Abubuwan da ake samu na thermal bazuwar mai, wato, sludge, sun zauna a saman injin ɗin, wanda ke haifar da gurɓacewar sa. Motar datti na iya haifar da zafi fiye da kima. Har ila yau, sludge barbashi sau da yawa ya ƙunshi superhard oxides da aiki a matsayin abrasives.
Wasu daga cikin oxides suna aiki da sinadarai. Wasu daga cikinsu suna da ikon fara aiwatar da lalata ko lalata sassan motar da ba ƙarfe ba (mafi yawan hatimin roba).
Potassium hydroxide yana aiki ta hanyoyi biyu:
- neutralization na wani ɓangare na sakamakon acid;
- rarrabuwar kai zuwa mafi ƙanƙanta mai yuwuwa ɓangarorin mahaɗan sludge da hana samuwar su.
Lokacin da injin ke aiki, adadin tushe na man injin yana raguwa, wanda shine tsari na yau da kullun.
Kiyasin adadin tushe na man inji
Kusan koyaushe ana jera lambar tushe akan kwandon man da ke bayan alamar. A halin yanzu, wannan adadi ya bambanta daga 5 (don mafi sauƙi kuma mafi arha mai) zuwa 14 mgKOH / g.
Sauran abubuwan daidai suke, ana samun ƙarin oxides a cikin injunan diesel. Da fari dai, wannan shi ne saboda abun da ke ciki na man fetur. Abubuwan da ke cikin sulfur da ke cikin man dizal ya fi na mai. Kuma sulfur yakan samar da oxides iri-iri idan aka fallasa yanayin zafi.
Na biyu, yanayin aiki na injin diesel ya fi tsanani. Mafi girman matsa lamba, mafi girman zafin jiki a cikin ɗakin konewa. A sakamakon haka, tsarin kona fitar da man ya fi aiki.
Saboda haka, don kawai man dizal, adadin tushe na 9 mgKOH / g da sama ana ɗaukar al'ada. Don injunan fetur, abubuwan da ake buƙata ba su da ɗan ƙima. Don injunan da ba a tilasta su da ke gudana akan mai, 7-8 mgKOH / g zai isa.
Koyaya, akwai mai wanda lambar tushe ta kasance ƙasa. Wannan ba yana nufin cewa man ba ya da kyau, kuma yana da kyau a guji amfani da shi. Dole ne a fahimci cewa kayan wanke irin wannan mai zai zama ƙasa. Kuma wannan yana nufin cewa kusa da maye gurbin (lokacin da farkon ƙananan adadin alkali ya ragu), tsarin samar da sludge zai hanzarta. Sabili da haka, ana ba da shawarar mai da ƙananan lambar tushe don canza sau da yawa.
Juya gefen tsabar kudin shine gaskiyar cewa tare da ƙarfafa fakitin ƙari, lambar tushe kuma tana raguwa. Wato, a ka'idar, musamman ga mai maras tsada, kawai babban adadin tushe ɗaya na iya nuna ƙarancin abun da ke ciki na wasu mahimman abubuwan ƙari.
