Bincike Kan Tasirin Micropowder Mai Ruwan Kasa Mai Fused Alumina Kan Taushin Fuskar Kayan Aiki
A cikin aikinmu, musamman a fannin gyaran saman ko sarrafa kayan aiki, muna magance alamar "taurin kai" kusan kowace rana. Kamar "yatsun hannu" na wani abu ne, wanda ke tantance kai tsaye ko wani shafi zai iya mannewa, yadda sassan da ke jure lalacewa suke, har ma da tasirin rufewa na haɗuwa. A yau, ba za mu yi magana game da waɗannan ka'idoji masu girma ba, amma mu zauna mu yi hira kamar abokan aikinmu game da tsohon abokinmu da muka fi sani - ƙaramin foda na alumina mai launin ruwan kasa - da kuma yadda yake "sarrafa" taurin saman kayan.
I. Da farko, bari mu fahimta: Menene ainihin foda mai launin ruwan kasa da aka haɗa da alumina?
Alumina mai launin ruwan kasaA takaice dai, shine abin da muke "gyara" ta amfani da kayan aiki kamar alumina da coke a cikin tanderun lantarki. Saboda yana ɗauke da wasu titanium da iron oxides, yana da launin ruwan kasa, shi ya sa aka san shi. Yana da tauri mai yawa, mai ƙarfi, kuma yana da araha, wanda hakan ya sa ya zama "babban abin da ake buƙata" wajen busar da yashi da niƙa.
Kuma kalmar "micropowder" ita ce mabuɗi. Tana nufin foda mai laushi da aka samu ta hanyar niƙawa da cire alumina mai launin ruwan kasa ta hanyar wani tsari na musamman, tare da girman barbashi yawanci yana farawa daga ɗaruruwan rabe zuwa dubban rabe. Kada ku raina wannan foda; ba yanzu wuka mai kauri ba ce ta yanke itace, amma wuka mai sassaka daidai.

II. Ta Yaya Yake "Sifantar" Fuskar? - Duniya Mai Sauƙin Ginawa Mai Sauƙi
Mutane da yawa suna tunanin cewa yin amfani da yashi kawai yana nufin yin amfani da yashi a saman, kuma da zarar ka yi amfani da shi, haka zai yi tauri. Wannan rabi gaskiya ne, amma ga waɗanda muke nazarin ƙananan foda, sauran rabin shine ainihin. Tasirin ƙananan foda na alumina mai launin ruwan kasa akan rashin ƙarfi a saman wani tsari ne mai rikitarwa, wanda na taƙaita shi zuwa manyan tasirin guda uku:
Tasirin "haƙa" (Yanke-yanke na Macro): Wannan shine mafi sauƙin fahimta. Ƙwayoyin ƙananan foda masu tashi da sauri, kamar ƙananan guduma da ƙwanƙwasa marasa adadi, suna shafar saman kayan. Ƙwayoyin masu tauri za su "ciji" kai tsaye ga kayan, suna samar da ƙananan ramuka. Wannan mataki shine babban abin da ke haifar da ƙaruwar ƙazanta a saman. Ka yi tunanin saman da aka fitar da ƙananan ramuka marasa adadi; bambancin tsakanin kololuwa da kwari yana ƙaruwa sosai, yana ɗaga ƙimar ƙazanta (misali, Ra, Rz).
Tasirin "girma" (lalacewar filastik): Wannan abin sha'awa ne. Lokacin da ƙwayoyin cuta ba su shafi saman kai tsaye ba, amma suna "girma" shi a kusurwa, ƙila ba za su iya yanke shi kai tsaye ta cikin kayan ba. Madadin haka, kamar yin noma, suna "matse" kayan saman zuwa gefuna, suna samar da "tsagi" mai ɗagawa. Wannan tsari ba ya cire kayan kai tsaye, amma ta hanyar lalata filastik, yana canza yanayin saman, yana ƙara bambanci tsakanin kololuwa da kwari.
Tasirin "ƙuntatawa" da "gajiya": A ƙarƙashin ci gaba da tasirin ƙananan ƙwayoyin cuta, saman abu yana fuskantar tsarin "gyara" ta hanyar maimaita tasirin. Tasirin farko na iya sassauta saman, amma ci gaba da tasirin a zahiri yana "ƙunta" saman, yana samar da Layer mai yawa da aka ƙarfafa. A lokaci guda, tasirin da aka maimaita yana haifar da gajiya a cikin ƙananan tsarin saman kayan, yana sauƙaƙa cire ƙwayoyin da ke gaba.
Kamar yadda kake gani, ko da sauƙin aikin lalata yashi ya ƙunshi tasiri uku a lokaci guda da kuma hulɗa da juna a duniyar da ba ta da ƙananan halittu: "haƙa," "hula," da "tamping."
III. Muhimman Abubuwa Uku Da Ke Shafar Sakamakon: Girman Barbashi, Matsi, da Kusurwoyi
Yanzu da muka fahimci ƙa'idar, ta yaya za mu "umarci"foda mai launin ruwan kasa da aka haɗa da aluminaDon cimma ƙaiƙayin saman da ake so a ainihin aiki? Ya dogara ne akan waɗannan muhimman abubuwa guda uku:
Abu na Farko: Girman Barbashi (Yaya foda ya kamata ya yi kauri?)
Wannan shine mafi mahimmancin ma'auni. A takaice dai, a ƙarƙashin yanayi iri ɗaya, yayin da ƙwayoyin suka yi kauri, haka nan ƙimar ƙaiƙayin saman zai fi girma. Yin amfani da foda mai kauri mai kauri mai kauri 80 zai samar da saman mai kauri sosai a cikin 'yan bugun kaɗan; amma idan kun yi amfani da W40 ko ma ƙaramin micropowder, saman da ya fito zai yi santsi sosai kuma yana da kyau. Wannan yayi kama da yin yashi da katako mai kauri da takarda mai kauri da takarda mai kauri - sakamakon ya bambanta sosai. Saboda haka, don samun ƙarancin ƙaiƙayin saman, zaɓar ƙaramin micropowder shine mataki na farko.
Abu na biyu mai mahimmanci: Matsin feshi (Nawa ne ƙarfin?)
Matsi shine kuzarin da ake bayarwa ga ƙwayoyin. Girman matsin lamba, saurin guduwar ƙwayoyin ke tashi, ƙarin kuzarin motsi da suke da shi, da kuma ƙaruwar tasirin "haƙa" da "garma", wanda hakan ke haifar da ƙarin tsauri. Duk da haka, akwai matsala: matsin lamba mafi girma ba koyaushe yake mafi kyau ba. Matsi mai yawa na iya haifar da yankewa fiye da kima, har ma da lalata daidaiton girman kayan aikin, ko ma karya kayan da suka lalace. Kwarewarmu ita ce, yayin da muke biyan buƙatun tsaftacewa da rashin ƙarfi, ya fi kyau a yi amfani da mafi ƙarancin matsin lamba—"yi amfani da mafi kyawun ƙarfe inda yake da mahimmanci."
Maɓalli na uku: Kusurwar fesawa (Daga wace hanya?)
Mutane da yawa suna watsi da wannan siga. Bincike ya nuna cewa lokacin da kusurwar fesawa take tsakanin 70° da 90° (kusan a tsaye), ƙaruwar ƙazanta ta fi muhimmanci saboda tasirin "haƙa" yana mamaye. Lokacin da kusurwar ta zama ƙarami (misali, 30°-45°), tasirin "haƙa" yana ƙara bayyana, wanda ke haifar da yanayin ƙazanta daban. Idan muna son tsaftace wani wuri amma ba ma son ya yi tsauri sosai, wani lokacin muna amfani da ƙaramin kusurwa don cimma daidaito tsakanin tsaftacewa da ƙazanta.
IV. "Sirrin" da Tunani a Aikace-aikacen Aiki
Ka'ida kaɗai ba ta isa ba; akwai "asirai" da yawa da za a iya samu a cikin ainihin ayyukan.
Misali, "zafin" kayan aikin (halayen da ke cikin kayan) yana da matuƙar muhimmanci. Yin amfani da sigogi iri ɗaya don na'urar ƙarfe mai ƙarfi da aka kashe idan aka kwatanta da aluminum mai laushi zai haifar da sakamako daban-daban. Kayan laushi sun fi saurin lalacewa ta filastik, suna samar da "rami" masu zurfi da faɗi kuma suna iya toshewa cikin sauƙi; kayan tauri suna iya fashewa da sauri, suna samar da ƙarin ramuka.
Wani misali kuma shine "rayuwar" ƙaramin foda.Foda mai launin ruwan kasa da aka haɗa da aluminaZai lalace ya kuma karye akan lokaci. Sabon rukuni na foda yana da girman barbashi iri ɗaya, gefuna masu kaifi, da ƙarfin yankewa mai ƙarfi, yana samar da rashin ƙarfi iri ɗaya da babban ƙarfi. Duk da haka, foda da aka yi amfani da shi, tare da gefuna masu zagaye da ƙaramin girman barbashi, yana "tsofaffi da lalacewa," tare da rage ƙarfin yankewa, yana iya samar da ƙaramin rashin ƙarfi iri ɗaya, wanda ya dace da kammala "satin" na saman da ya dace. Duk ya dogara da buƙatun aikin ku.
Saboda haka, nazarin tasirinfoda mai launin ruwan kasa mai hade da aluminaRashin kyawun yanayi a saman ba wai kawai batun duba kayan da kuma aiki daidai ba ne. Fasaha ce ta sarrafa su daidai a duniyar da ba ta da yawa. Muna buƙatar zama kamar ƙwararren likitan gargajiya na ƙasar Sin, wanda ya ƙware a fannin halaye da hanyoyin "ganye masu magani" kamar "ƙwayoyi, matsi, da kusurwa," sannan ya haɗa su da "tsarin" kayan aikin, domin a rubuta mafi inganci "magani" da kuma cimma cikakkiyar rashin kyawun yanayi.
