Kodi n’zothekadi kuona mtundu wa zitsulo zimene zikupangidwa poyang’ana zipsera?
Inde, n’zotheka kudziŵa bwino za mtundu wa zitsulo zimene zikupangidwa poyang’ana zonyezimira zimene zimatuluka popanga makinawo. Njira imeneyi, yomwe imadziwika kuti spark test, ndiyofala m'mafakitale opangira zitsulo.
Chitsulo chikagwiritsidwa ntchito ngati kupera kapena kudula, chimatulutsa zonyezimira zokhala ndi mikhalidwe yosiyana malinga ndi kapangidwe kake. Zinthu monga kupangidwa kwa mankhwala, kuuma, ndi kutentha kwa chitsulo kumakhudza mtundu, mawonekedwe, kutalika, ndi mphamvu ya zitsulozo.
Akatswiri odziwa bwino ntchito zam'ma workshop omwe apeza chidziwitso ndi ukatswiri pakuyesa spark amatha kupanga ziganizo zodziwika bwino za mtundu wachitsulo chomwe chimapangidwa poyang'ana mosamalitsa zonyezimirazi. Komabe, ndikofunikira kuzindikira kuti kuyesa kwa spark sikukhala kopusitsa nthawi zonse ndipo kungafunike kuwunikiranso kapena kutsimikizira pogwiritsa ntchito njira zina kulondola kwathunthu.
Ngakhale kuyesa kwa spark kumatha kupereka zidziwitso zofunikira pamtundu wazitsulo zonse, kuyenera kuthandizidwa ndi njira zina monga spectroscopy, kusanthula mankhwala, kapena njira zozindikiritsira zakuthupi kuti mupeze zotsatira zolondola komanso zomveka.
Mfundo yozindikiritsa
Pamene amakina zitsulochitsanzo ndi pansi pa gudumu akupera, ndi mkulu-kutentha zabwino zitsulo particles akuyembekezeredwa pamodzi tangential malangizo a akupera gudumu kasinthasintha, ndiyeno kuzitikita ndi mpweya, kutentha akupitiriza kukwera, ndi particles ndi mwachiwawa oxidized ndi kusungunuka. Mitsinje yowala.
Njere za abrasive zimakhala ndi kutentha kwakukulu, ndipo pamwamba pake ndi oxidized kwambiri kuti apange filimu ya FeO. Mpweya wa carbon muzitsulo ndi wosavuta kuchitapo kanthu ndi mpweya pa kutentha kwakukulu, FeO + C → Fe + CO, kotero kuti FeO imachepetsedwa; Fe yochepetsedwa idzakhala oxidized kachiwiri, ndiyeno kuchepetsedwa kachiwiri; izi makutidwe ndi okosijeni-kuchepetsa anachita ndi cyclical ndipo adzapitiriza CO mpweya kwaiye, ndipo pamene chitsulo okusayidi filimu pa tinthu pamwamba sitingathe kulamulira kwaiye CO mpweya, ndi mkangano chodabwitsa zimachitika ndipo zoyaka moto.
Ngati particles zophulika zikadali ndi FeO ndi C zomwe sizinachitepo kanthu, zomwe zidzachitike zidzapitirira, ndipo padzakhala zophulika ziwiri, zitatu kapena zingapo.
Mpweya muzitsulo ndiye chinthu chofunikira kwambiri popanga zipsera. Liticnc zitsuloili ndi manganese, silicon, tungsten, chromium, molybdenum ndi zinthu zina, ma oxides awo amakhudza mizere, mitundu ndi maiko amoto. Malinga ndi mawonekedwe a spark, zomwe zili mu kaboni ndi zinthu zina zachitsulo zimatha kuweruzidwa mozama.
Chitsanzo cha Spark
Ziwawazi zomwe zimapangidwa pamene chitsulo chaphwanyidwa pa gudumu lopera, chimakhala ndi timizu, zonyezimira zapakati ndi mchira kuti zipange mtolo. Mzere wofanana ndi mzere wopangidwa ndi tinthu tating'ono tomwe timatentha kwambiri timatchedwa streamline.
Malo owala ndi okhuthala pamayendedwe amatchedwa node. Phokoso likaphulika, mizere yayifupi ingapo imatchedwa mizere ya awn. Zonyezimira zopangidwa ndi mizere ya awn zimatchedwa maluwa a chikondwerero.
Ndi kuchuluka kwa kaboni, kuphulika kosalekeza pamzere wa awn kumatulutsa maluwa achiwiri ndi maluwa apamwamba. Madontho owala omwe amawonekera pafupi ndi mzere wa awn amatchedwa pollen.
Chifukwa cha mankhwala osiyanasiyana a zitsulo zachitsulo, zipsera zamitundu yosiyanasiyana pa mchira wa streamline zimatchedwa maluwa a mchira. Maluwa a mchirawo amakhala ngati maluwa a mchira wa bract, maluwa ngati mchira wa nkhandwe, maluwa ngati mchira wa chrysanthemum ndi maluwa owoneka ngati nthenga.

Mpweya ndiye chinthu chofunikira kwambiri pazambiri zachitsulo ndi zitsulo, komanso ndiye gawo lalikulu lomwe limatsimikiziridwa ndi njira yozindikiritsa spark. Chifukwa cha mitundu yosiyanasiyana ya kaboni, mawonekedwe a spark amasiyana.
① Mitsinje yachitsulo chochepa cha carbon ndi yokhuthala komanso yopyapyala, yokhala ndi maluwa ochepa otuluka komanso maluwa anthawi imodzi, ndipo mizere ya awn ndi yokhuthala, yayitali komanso yowala. Mtundu wonyezimira ndi udzu wachikasu woderapo.

Poyerekeza ndi chitsulo chochepa cha carbon, pali maluwa ochulukirapo, ndipo mawonekedwe a maluwa ndi aakulu. Pali maluwa oyambira ndi maluwa achiwiri, okhala ndi mungu wocheperako. Mtundu wonyezimira ndi wachikasu.

Masamba obiriwira amakhala obiriwira, okhala ndi masamba ambiri. Nthawi zambiri amakhala maluwa achiwiri okhala ndi mungu wambiri komanso maluwa ophulika. Mchirawo umakula pang'onopang'ono ndikulowa mu mawonekedwe a arc, ndipo mtundu wake nthawi zambiri umakhala wofiira-lalanje. Mu mayeso a spark, zimamveka zofewa.
Spark makhalidwe a aloyi zitsulo
Mawonekedwe a spark a chitsulo cha alloy amagwirizana ndi zinthu zomwe zili ndi alloying. Nthawi zambiri, zinthu monga faifi tambala, silicon, molybdenum, ndi tungsten zimalepheretsa kuphulika, pomwe zinthu monga manganese, vanadium, ndi chromium zimatha kulimbikitsa kuphulika. Choncho, chizindikiritso cha chitsulo cha alloy ndi chovuta kumvetsa.
Nthawi zambiri, mtolo wachitsulo cha chromium ndi woyera komanso wowala, mtsinjewo umakhala wandiweyani pang'ono komanso wautali, ndipo kuphulika kumakhala duwa limodzi, mtundu wamaluwa ndi wokulirapo, mawonekedwe a nyenyezi yayikulu, mafoloko ndi ambiri komanso owonda. , ndi mungu wosweka, ndipo pakati pa kuphulikako kumakhala kowala kwambiri.
Mitolo ya chitsulo chosapanga dzimbiri cha nickel-chromium ndi yopyapyala, kuwala kumakhala kocheperako, ndipo imaphulika kukhala duwa, yokhala ndi nthambi zisanu kapena zisanu ndi chimodzi zokhala ngati nyenyezi, ndipo nsonga yake imaphulika pang'ono.
Zitsulo zachitsulo zothamanga kwambiri zimakhala zowonda, zokhala ndi mitsinje yochepa, palibe kuphulika, mdima wofiira wamtundu, mitsinje yapakati pamizu ndi pakati, ndi maluwa a mchira wa arc.
