Udindo Wofunika Kwambiri wa White Fused Aluminium Sandblasting mu Pretreatment ya Chitsulo
Ife omwe tili mumakampani awa tikudziwa kuti ziwalo zachitsulo, monga anthu, zimafunika kukonzedwa bwino tisanapite kukakumana ndi alendo. Ngati zili ndi mafuta, dzimbiri, ndi utoto wakale, aliyense adzagwedeza mitu yawo. Gawo loyamba mu "kukonzekera" uku ndi kukonza zinthu pasadakhale, ndipo kupukuta mchenga koyera kwa aluminiyamu ndi gawo lofunika kwambiri pankhaniyi. Lero, tikambirana momwe zinthuzi zimagwirira ntchito yake yosasinthika pakukonza zinthu pasadakhale.
I. Si “Mchenga” Wonse Womwe Uli Aluminium Yoyera Yophatikizidwa: N’chiyani Chimaupangitsa Kukhala Wamphamvu Kwambiri?
Anthu atsopano mumakampani angaganize kuti kuphulitsa mchenga ndi kungogwiritsa ntchito mchenga kugunda pamwamba pa chitsulo, kodi ndi chiyani chapadera kwambiri pa izi? Chabwino, ndi malingaliro osamveka bwino. Mukuyesera kugwiritsa ntchito mchenga wa m'mtsinje kapena mchenga wa quartz? Zinthu zimenezo sizolimba mokwanira, zimapanga fumbi lambiri, ndizoipa pa thanzi la ogwira ntchito, ndipo nthawi zambiri zimasiya zotsalira pamwamba pambuyo pophulitsa. Alumina yoyera yosakanikirana ndi yosiyana; ndi katswiri weniweni.
Taganizirani izi:alumina woyera wosakanikiranandi corundum yopangidwa, yoyera kwambiri, ndipo monga momwe dzina lake likusonyezera, yoyera kwambiri. Koma ndi yolimba kwambiri! Kulimba kwake kuli pakati pa zinthu zambiri zowononga, yachiwiri kuposa silicon carbide ndi diamondi. Izi zikutanthauza kuti ikagunda pamwamba pa chitsulo, imagwira ntchito bwino kwambiri, kudula zinyalala zosakanikirana ndi liwiro la mphezi.
Komanso, ndi yokhazikika kwambiri pa mankhwala, ilibe silikoni yaulere, ndipo fumbi lake ndi labwino kwambiri m'mapapo. Imapanga tinthu tating'onoting'ono tofanana, mosiyana ndi zinthu zina zomangira zomwe zingapangitse kuti ikhale yolimba. Chofunika kwambiri, sichikopa fumbi kapena dothi; imakhalabe yoyera ndipo siidzalowetsa zinyalala pamwamba pa chitsulo, chomwe ndi chinthu chofunikira kwambiri mukapaka zokutira kapena zophimba pambuyo pake. Chifukwa chake, kusankha ngati chinthu choyamba kumapereka mtendere wamumtima.
II. Njira Yake Yazing'ono Zitatu: Kuyeretsa, Kukonza, ndi Kulimbitsa
Kuphulika kwa alumina woyera wosakanikirana kumayang'ana kwambiri njira zitatu zazikulu zochizira chisanadze: kuyeretsa, kupukuta, ndi kulimbitsa. Tiyeni tikambirane chimodzi ndi chimodzi.
Chingwe Choyamba: Kuyeretsa Bwino, Kusasiya Mavuto Pambuyo pake
Ichi ndi chinthu chosavuta kwambiri, komanso chovuta kwambiri. Zitsulo zochokera ku mphero yachitsulo, kapena zosungidwa m'nyumba yosungiramo zinthu kwa nthawi yayitali, zimakhala ndi malo omwe ali ngati "thumba losakanikirana": oxide scale (yomwe ndi dzimbiri labuluu kapena lofiirira), welding slag, madontho amafuta ouma, zokutira zakale… Kutsuka ndi asidi wa mankhwala sikophweka, koma sikuli bwino kwa chilengedwe ndipo kungawononge substrate. Kupera ndi dzanja ndi gudumu la waya? Zimenezo sizigwira ntchito bwino kwambiri.
Kuphulika kwa alumina yoyera yosakanikirana sikusamala chilichonse mwa zimenezo. Motsogozedwa ndi kuthamanga kwa mpweya, tinthu tating'onoting'ono ta alumina toyera tosakanikirana, ngati zipolopolo, "whoosh," tomwe timapita pamwamba pa ntchito. Izi sizongosangalatsa chabe; ndi njira yeniyeni yochotsera. Oxide scale ndi welding slag ndi "paper tigers" zomwe zilipo, nthawi yomweyo zimasweka ndikuchotsedwa. Mukamaliza kupopera, yang'ananinso! Mtundu wachilengedwe wachitsulo umaonekera, woyera komanso wosalala, ngati tofu wopangidwa mwatsopano—mawonekedwe osangalatsa. Gawo loyamba loyeretsa ili lili ngati kukonzekera "canvas" yoyera kuti igwiritsidwe ntchito pambuyo pake.
Nkhwangwa Yachiwiri: Kukwecha Kwambiri, Kugwira Chophimba
Kodi kuyeretsa n'kokwanira? Ayi ndithu! Tangoganizirani malo osalala, ofanana ndi galasi; ngati muwapopera utoto kapena kuupaka ufa, kodi kumamatirako kudzakhala bwino? Zili ngati kumata nyuzipepala pagalasi—idzagwa pang'ono mukakhudza. Chodabwitsa chachiwiri cha kuphulika kwa mchenga woyera wa corundum ndi "kukwinya" malo osalala awa.
Sichiwononga, koma m'malo mwake "ziboliboli." Chimapanga mabowo ang'onoang'ono ambiri, ofanana pamwamba pa chitsulo, chomwe timachitcha "mawonekedwe a nangula" kapena "kukhwima." Musanyoze mabowo awa; amawonjezera kwambiri malo a pamwamba, monga kupereka chophimba ndi "manja" ang'onoang'ono zikwizikwi, omwe amachigwira mwamphamvu. Izi zimapangitsa kuti filimu ya utoto ndi pulasitiki zigwirizane kwambiri, zomwe zimapangitsa kuti zisawonongeke kapena kusweka. Kukhwima kumeneku, komwe kumayesedwa ndi zida zaukadaulo ngati "kukhwima," ndi chinthu chomwe mmisiri wodziwa bwino ntchito angadziwe nthawi yomweyo pokhudza: "Hmm, ntchito iyi yachitika bwino, utoto umamatira bwino!"
Gawo Lachitatu: Kulimbitsa Mosaoneka, Kukulitsa Nthawi ya Moyo
Gawo lachitatu ili likufanana ndi "mphamvu yamkati" - yosaoneka komanso yosaoneka, koma ubwino wake ndi weniweni. Kuthamanga kwa tinthu tating'onoting'ono ta corundum yoyera pamwamba pa chitsulo kwenikweni ndi njira yochepa "yogwira ntchito yozizira". Imayambitsa kusokonekera kwa lattice pamwamba pa chitsulo, zomwe zimapangitsa kuti pakhale kupsinjika.
Kodi kupsinjika maganizo n’chiyani? Taganizirani motere: kuli ngati kuyika "suti yosaoneka" pamwamba pa chitsulo, zomwe zimapangitsa kuti kapangidwe ka mamolekyu a chinthucho kakhale kakang'ono komanso kolimba. Izi zimawonjezera mphamvu ya kutopa kwa chitsulocho ndipo zimawonjezera kukana kwake ku dzimbiri, zomwe zimapangitsa kuti ntchitoyo ikhale yolimba. Pazinthu zina zofunika kwambiri, monga ma crankshaft a injini ndi zida zolandirira ndege, njirayi ndi yofunika kwambiri.
III. Ubwino wa Ntchito Umadalira Momwe Mumaigwiritsira Ntchito
Zipangizo zokha zitha kukhala zabwino, koma kuti ntchitoyo ichitike bwino, zonse zimadalira momwe mumazigwiritsira ntchito. Pali njira zingapo zochitira izi.
Choyamba, muyenera kusankha grit yoyenera. Grit yolimba kwambiri ili ndi ntchito zake, ndipo grit yopyapyala ili ndi zofunikira zake. Ngati mukufuna kuchotsa dzimbiri kapena utoto wokhuthala, muyenera kugwiritsa ntchito grit yolimba kwambiri, monga maukonde 20 kapena 30, kuti mukhale ndi mphamvu zambiri. Ngati mukufuna kutsuka bwino kapena kupanga nangula wofewa kwambiri, muyenera kugwiritsa ntchito grit yopyapyala, monga maukonde 80 kapena 100. Simungagwiritse ntchito mchenga womwewo pazinthu zonse.
Chachiwiri, muyenera kuwongolera kuthamanga kwa mpweya ndi ngodya. Ngati kuthamanga kwa mpweya kuli kotsika kwambiri, chopoperacho chidzakhala chofewa kwambiri komanso chofooka; ngati kuthamanga kwa mpweya kuli kokwera kwambiri, chingathe kusokoneza mosavuta zida zogwirira ntchito zopyapyala kapena kuswa chopoperacho, zomwe zimapangitsa kuti zotsatira zake zikhale zoipa. Izi zikugwiranso ntchito pa ngodya ya mfuti yopopera. Pa kuyeretsa kwabwinobwino, ngodya ya madigiri 45 mpaka 70 ndiyo yoyenera kwambiri. Ngati ngodyayo ndi yaying'ono kwambiri, imakhala ngati "kukanda pansi," zomwe zimapangitsa kuti zotsatira zake zikhale zosafanana.
Pomaliza, malo ozungulira ayenera kukhala ouma.Alumina yoyera yosakanikiranandi yabwino kwambiri m'njira zonse, kupatulapo kuti "imakhudzidwa ndi chinyezi." Ikanyowa, imalumikizana mosavuta, kutseka nozzle ya mfuti yopopera, zomwe zingayambitse kuchedwa kwakukulu. Chifukwa chake, gwero lathu la mpweya liyenera kukhala ndi cholekanitsa mafuta ndi madzi, ndipo thanki yosungira mchenga iyeneranso kutetezedwa ku chinyezi.
Chifukwa chake, chonde musaganize za alumina yoyera yosakanikiranakuphulika kwa mchengangati ntchito yosavuta "yoyeretsa". Pankhani yokonza zitsulo, ndi yodzaza ndi zinthu zonse, imagwira ntchito ngati "woyeretsa," "wosema," komanso "wolimbitsa." Imapanga zotsatira zoyera, zofanana, komanso zomatira bwino, ndipo "imalimbitsa" ziwalo zachitsulo, ndikuyika maziko abwino azinthu zina monga kupopera, kuyika ma electroplating, ndi kuwotcherera. Pantchito zamafakitale, timakhulupirira kuti "maziko ofooka amabweretsa kusakhazikika." Kukonzekera kumeneku ndi "maziko" a ntchito zonse zokongola. Kugwiritsa ntchito bwino alumina sandblasting yoyera kungawoneke ngati sitepe yowonjezera, koma kwenikweni kumasunga ndalama zambiri pakukonzanso ndi kukonza pambuyo pake. Ndi kusinthana koyenera mosasamala kanthu momwe mukuyang'ana! Zili ngati "ng'ombe yakale" yopanda phokoso koma yodalirika kwambiri pakukonza zitsulo, yosakukhumudwitsani pamene kuli kofunikira kwambiri.
