Ndi chiyanimendulochonyezimira ndi chowoneka chapamwamba kwambiri?
Zitsulo zimagwirizana kwambiri ndi mpweya chaka chonse, ndipo njira nthawi zambiri zimawonjezeredwa pamwamba pa mendulo, zikho, chikumbutso, ndi zina zotero kuti ziteteze zinthu zachitsulo.
Zotsatirazi ndi mendulo zamasewera a Winter Olympics a 2022, omwe aphulitsidwa ndi mchenga pamtunda. Lero, tiyeni tidziwitse njira zodziwika bwino zopangira mchenga.
Sandblasting ndi njira yothetsera pamwamba pa workpieces. Pogwiritsa ntchito mpweya woponderezedwa ngati mphamvu, mtengo wa jet wothamanga kwambiri umapangidwa kuti upopera zinthu (mkuwa, mchenga wa quartz, mchenga wa diamondi, mchenga wachitsulo, mchenga wa m'nyanja) pa liwiro lalikulu pamwamba pa workpiece kuti ichiritsidwe, kuchititsa kusintha. mawonekedwe kapena mawonekedwe a workpiece pamwamba. Chifukwa cha kukhudza ndi kudula zotsatira za abrasives pamwamba pa workpiece, pamwamba pa workpiece amapeza mlingo wina wa ukhondo ndi roughness osiyana, amene bwino makina katundu wa workpiece pamwamba. Chifukwa chake, kukana kutopa kwa workpiece kumatheka, kumamatira pakati pake ndi zokutira kumawonjezeka, kulimba kwa zokutira kumakulitsidwa, komanso kumathandizira kuwongolera ndi kukongoletsa kwa zokutira.
Zopangira sandblasting mankhwala
Kuphulitsa mchenga: Mawu aukadaulo omwe amagwiritsidwa ntchito popanga ndalama zagolide ndi siliva. Pakupanga nkhungu ya golide ndi siliva, makulidwe osiyanasiyana ndi zitsanzo za mchenga wachitsulo amagwiritsidwa ntchito kupopera gawo lachitsanzo pamalo abwino kwambiri achisanu. Popanga ndalama za golidi ndi siliva, mawonekedwe okongola amawonekera pagawo lachitsanzo, kuonjezera kumverera kwa dimensionality ndi layering. Sandblasting: (kunena za kuchotsa dzimbiri pazitsulo kapena plating pazitsulo) amagawidwa mu mchenga wamba wa quartz ndi mchenga wa quartz woyengedwa: wokhala ndi kuuma kwakukulu ndi zotsatira zabwino zochotsa dzimbiri.
Sandblasting ndondomeko
Pre processing stage
Gawo lachisamaliro la ndondomekoyi limatanthawuza chithandizo chomwe chiyenera kuchitidwa pamtunda wa workpiece musanapopedwe kapena wokutidwa ndi wosanjikiza wotetezera. Ubwino wa chithandizo chisanachitike muukadaulo wa sandblasting umakhudza kumamatira, mawonekedwe, kukana chinyezi, komanso kukana kwa dzimbiri kwa zokutira. Ngati ntchito yochizira isanayambike sikuchitika bwino, dzimbiri lidzapitirira kufalikira pansi pa zokutira, zomwe zimapangitsa kuti chophimbacho chiwonongeke. Pambuyo kuyeretsa bwino pamwamba ndi kuyeretsa kosavuta kwa workpiece, moyo wokutira ukhoza kufananizidwa ndi nthawi 4-5 pogwiritsa ntchito njira ya dzuwa. Pali njira zambiri zoyeretsera pamwamba, koma zovomerezeka kwambiri ndizoyeretsa zosungunulira, kutsuka asidi, zida zamanja, ndi zida zamanja.
Njira siteji
Njira yopangira mchenga imagwiritsa ntchito mpweya woponderezedwa ngati mphamvu yopanga mtengo wothamanga kwambiri wa jet, womwe umapopera zipangizo ndi zipangizo zina pamwamba pa workpiece kuti zithetsedwe pa liwiro lalikulu, zomwe zimapangitsa kusintha pamwamba pa workpiece. Chifukwa cha kukhudza ndi kudula zotsatira za abrasives pa workpiece pamwamba, workpiece pamwamba amapeza mlingo wina wa ukhondo ndi roughness osiyana, kuwongolera mawotchi zimatha workpiece pamwamba.
Ubwino waukadaulo wa sandblasting
（1） Kupaka ndi kumangiriza chisanachitike chithandizo cha sandblasting kumatha kuchotsa dothi lonse monga dzimbiri pamwamba pa chogwirira ntchito, ndikukhazikitsa dongosolo lofunikira kwambiri (lomwe limadziwika kuti ndi laukali) pamtunda. Ikhozanso kukwaniritsa madigiri osiyanasiyana a roughness mwa kusinthanitsa ma abrasives amitundu yosiyanasiyana ya tinthu, monga zida zowuluka zouluka, kuwongolera kwambiri mphamvu zomangira za zokutira ndi zokutira. Kapena pangani zomangira zomatira kukhala zolimba komanso zamtundu wabwino.
(2) The akhakula pamwamba castings ndi kuyeretsa ndi kupukuta pambuyo kutentha mankhwala akhoza kutsukidwa ndi sandblasting, amene angathe kuchotsa dothi onse (monga okusayidi khungu, madontho mafuta, etc.) pamwamba pa phula ndi kutentha mankhwala workpieces. Kupukuta pamwamba kumapangitsa kuti ntchitoyo ikhale yosalala, kuwonetsa yunifolomu ndi mtundu wachitsulo wosasinthasintha, kupangitsa maonekedwe kukhala okongola komanso okongola.
(3) Kuyeretsa kwa ma Burr ndi kukongoletsa pamwamba pa sandblasting kumatha kuyeretsa ma burrs ang'onoang'ono pamwamba pa zida zogwirira ntchito, kupangitsa kuti zinthu zogwirira ntchito zikhale zosalala, kuthetsa kuvulaza kwa ma burrs, ndikuwongolera kalasi. Ndipo sandblasting imatha kupanga ngodya zazing'ono zozungulira pamawonekedwe a workpiece pamwamba, ndikupangitsa kuti ikhale yokongola komanso yolondola.
(4) Pambuyo pa kuphulika kwa mchenga, mawonekedwe a yunifolomu ndi abwino kwambiri a concave amatha kupangidwa pamwamba, kulola mafuta odzola kuti asungidwe, potero kumapangitsa kuti mafuta azikhala bwino komanso kuchepetsa phokoso kuti awonjezere moyo wautumiki.
(5) Pazinthu zina zapadera zogwirira ntchito, kuphulika kwa mchenga kumatha kukwaniritsa mawonekedwe osiyanasiyana kapena zotsatira za matte mwakufuna kwake. Monga kupukuta zitsulo zosapanga dzimbiri ndi mapulasitiki, kupukuta zinthu zayade, kukonza matte pamwamba pamipando yamatabwa, mapatani azithunzi pamagalasi oundana, ndi kukhwinyata kwa nsalu.
Ponseponse, zimapangitsa kuti mendulo yagolide iwoneke yapamwamba kwambiri, yokhazikika komanso yolimba
