Ma'anar na'urar auna aikin ruwa na Shanghai Baoshan:

Microbial girma: aikin ruwa yana da alaƙa da girma na ƙwayoyin cuta (kamar kwayoyin cuta, ƙwayoyin cuta, yisti, da sauransu). Yawancin ƙwayoyin cuta suna buƙatar wasu ayyukan ruwa don girma. Misali, ƙwayoyin cuta yawanci suna girma a cikin yanayin aw > 0.91, kuma ƙwayoyin cuta suna girma a cikin yanayin aw > 0.7.

Sunadarai: Ayyukan ruwa kuma suna shafar saurin halayen sunadarai, musamman halayen da suka shafi ruwa. Ƙananan aikin ruwa yana taimakawa wajen jinkirta waɗannan amsoshin, don haka inganta kwanciyar hankali na abu.

Ajiyar Abinci: A kimiyyar abinci, aikin ruwa shine muhimmin abu wanda ke shafar lokacin abinci da aminci. Ƙananan aikin ruwa yana taimakawa rage girman ƙwayoyin cuta da jinkirin lalacewar abinci.

Taste da texture: ruwa aiki kuma da alaƙa da texture da dandano abinci. Misali, abinci mai ƙarancin ruwa yawanci ya bushe, yayin da abinci mai ƙarancin ruwa zai iya zama mai zafi.

Common aikace-aikace na Shanghai Baoshan ruwa aiki auna na'urar:

Abinci masana'antu: ruwa aikin sarrafawa na kayayyakin kamar bushe 'ya'yan itace, nama, gurasa da sauransu don tsawaita rayuwa.

Masana'antar magunguna: Tabbatar da kwanciyar hankali na magunguna don kauce wa lalacewar magunguna.

Conductive kumfa liner, dangantaka tsakanin m canje-canje na juriya da matsawa kashi ne m tsari a lokacin da aka matsawa. Ga wani bincike game da conductive kumfa liner matsawa kashi da kuma juriya dynamic ganowa curve tsari:

1. Basic tsari da halaye na conductive kumfa liner

Mai gudanarwa kumfa yawanci ƙunshi kumfa substrate tare da mai gudanarwa particles (kamar carbon baƙar fata, karfe foda, da dai sauransu). Yana nuna babban porosity da ƙananan juriya a lokacin da ba a matsawa ba, yayin da a lokacin da ake matsawa, porosity ya ragu, canjin kayan aiki da canjin hanyar gudanarwa zai haifar da canjin juriya.

2. Matsa kashi dangantaka da juriya canji

· farko yanayin: a lokacin da conductive kumfa ba matsawa, da kumfa porosity ne mafi girma, da halin yanzu kwarara hanya ne m dogon, da juriya ne mafi girma.

· Matsa tsari: Tare da matsa kumfa, porosity a hankali rage, lamba tsakanin conductive particles a kumfa tsarin karu, hanyar halin yanzu kwarara ya gajere, haifar da juriya rage.

· Matsawa zuwa wani kashi: Lokacin da kumfa aka matsawa da babban, porosity kusan gaba daya ya ɓace, tsarin kumfa zai iya rushewa ko zama m, da juriya canje-canje a hankali zama m. A wannan lokacin, canje-canje na juriya sau da yawa suna daidaitawa, ko kuma ana iya samun karuwar juriya mai yawa saboda lalacewar kayan da ba za a iya dawowa ba.

3. juriya dynamic canji curve Mechanism

Canje-canje na juriya a lokacin matsawa a cikin conductive kumfa liner yawanci bayyana a matsayin matakai masu zuwa:

· Mataki na 1: Low matsa mataki (farko mataki):

· A wannan mataki, juriya a hankali rage tare da karuwar matsawa. Yayin da tsarin kumfa ke matsawa a hankali, yankin tuntuɓar tsakanin ƙwayoyin mai gudanarwa yana ƙaruwa, hanyar da yanzu ke wucewa ta zama gajeren, wanda ke haifar da rage juriya. Canjin juriya a wannan matakin yana da sauƙi.

· Mataki na 2: Matsakaicin matsa mataki:

· Lokacin shiga matsakaicin matsa mataki, porosity na kumfa fara rage sosai, geometry siffar kumfa da kuma layi na conductive particles iya canzawa, canje-canje na juriya ne mafi bayyane, da kuma saurin da juriya rage iya sauri.

· Mataki na 3: High matsa yawan mataki (matsa iyaka mataki):

· Lokacin da matsawa rate kusa da iyaka, da porosity na kumfa a yau da kullun ɓace, da kuma canje-canje na juriya m. A wannan matakin, idan kumfa ya bayyana karkatarwa ko lalacewa, juriya na iya ƙaruwa ba zato ba tsammani, yana nunawa a matsayin haɓaka mai tsanani na juriya.

· Mataki na 4: Mataki na karkatarwa (idan akwai):

Idan kumfa ya faru a karkashin matsawa mai yawa (kamar karya na kayan aiki, faduwa da ƙwayoyin lantarki, da dai sauransu), juriya za ta sami haɓaka mai tsanani. Wannan yanayin yawanci ya bayyana bayan matsawa ya kai wani iyaka.

4. Abubuwan da ke shafar canje-canje na juriya

· Rarraba na conductive particles: canje-canje na juriya na conductive kumfa ya shafi daidaitaccen rarraba na conductive particles. Idan kwayoyin da ke gudanarwa suna rarraba daidai a cikin kumfa, canje-canjen juriya za su zama masu laushi.

· Elasticity da filastik na kayan: bambancin elasticity da filastik na daban-daban mai gudanarwa kumfa zai shafi canje-canje na juriya. A cikin kumfa mai laushi, juriya tana canzawa sosai lokacin matsawa, yayin da a cikin kumfa mai wuya, juriya tana iya canzawa sosai.

· Matsawa gudun: matsawa gudun kuma zai shafi m canje-canje na juriya, da sauri matsawa iya haifar da wani mafi girma kewayon gida damuwa mayar da hankali, haifar da m canje-canje juriya.

5. Gwajin gwaji na juriya da matsa kashi

A gwaji, sau da yawa gano canje-canje na m juriya a lokacin matsawa tsari ta hanyar matakai masu zuwa:

· Amfani da matsin lamba firikwensin don rikodin matsa kashi na kumfa.

· Amfani da hanyar bincike huɗu ko juriya strain gauge don saka idanu kan canje-canje na juriya a cikin kumfa liner a ainihin lokacin.

· Kwatanta matsa kashi tare da juriya darajar, samun juriya-matsa kashi curve.

6. Taƙaitaccen

Akwai rikitarwa dangantaka tsakanin resistive dynamic canje-canje na conductive kumfa liner da matsawa kashi. A lokacin matsawa na farko, juriya yawanci tana raguwa saboda tsarin kumfa ya fi ƙarfi, kuma haɗin tsakanin ƙwayoyin mai gudanarwa ya ƙaru. Amma yayin da matsawa ke ci gaba, canje-canjen juriya a hankali suna daidaitawa, kuma ana iya samun canje-canje masu tsanani saboda karkatarwa ko lalacewar kayan aiki bayan kai wasu kashi na matsawa.
