Abrasives chotchuka ntchito zosiyanasiyana njira mafakitale kuphatikizapo kutchukitsa ndi kutsirizitsa kwa zigawo zopangwidwa kuchokera ku zipangizo zosiyanasiyana monga matabwa, galasi, konkire, pulasitiki, mwala, chitsulo, chitsulo, wapamwamba-kasakaniza wazitsulo ndi zosakhudzana ndi zitsulo akakhala ndi zambiri zosowa zinthu monga ndolo, kuwala ndi mbali amagetsi.
Mbiri yakale, zipangizo abrasive anali makamaka linachokera ku mchere zachilengedwe monga emery, khwatsi mchenga ndi diamondi. Today Komabe, abrasives makampani pafupifupi yozungulira kwathunthu pa angapange, amene ali kutali kwambiri yena zikuchokera ndi yosafuna kuposa akapolo anzawo akale achilengedwe. angapange zambiri zambiri yosafuna monga iwo amakhala ndi-mankhwala kapena zinyalala mitsinje njira yotulutsa iwo monga mphamvu m'badwo ndi zitsulo yadothi. Ngakhale mchere zachilengedwe akadali ndi ofala, iwo amakhala ntchito ntchito apadera kwambiri monga kupukuta ndi kuwamaliza zabwino chifukwa mtengo awo apamwamba.
Mitundu itatu yoyamba ya abrasives kupanga ndi TACHIMATA, angongole ndi abrasives lotayirira. TACHIMATA abrasives muli ndi pepala, kansalu kapena zina amuthandiza ofanana. Angongole abrasives monga mawilo akupera ndi timitengo. abrasives lotayirira ntchito kabotolo ndi angagwere chifukwa, mwa zina, kuchotsa utoto ndi dzimbiri ndi yokonza pamalo latsopano. Mtundu uliwonse wa mankhwala abrasive makamaka zimatenga amafuna osiyana mu mawu a padziko specifications mapeto, mawonekedwe ndi kukula kwa chigawo cha, katundu thupi (monga kuuma, mphamvu ndi kutentha malire) ndi zofunika zambiri za umapezeka kapena kumaliza ndondomeko. Makhalidwe a zinthu abrasive (mwachitsanzo, kukula, mawonekedwe, mphamvu kachulukidwe ndi kuuma) ali ovuta ntchito yake yeniyeni, monga ndi katundu nkhani masanjidwewo (mwachitsanzo, utomoni, vitreous kapena zitsulo) ndi digiri ya porosity.
Mapulogalamu kwa abrasives lotayirira osiyanasiyana monga kuyeretsa pamwamba ndi peening, kuti kubwezeretsa ndi pamwamba yokonza zipangizo zokutira zozitetezera. A yachiwiri yaikulu msika abrasives lotayirira ndi kuphulika kuyeretsa ndi repainting wa milatho ndi overpasses. Kuwonjezera misika awiriwa, pali mazana ntchito mafakitale kumene abrasives lotayirira ntchito yokonza pamwamba, pamwamba kuyeretsa ndi monga zikuluzikulu za mankhwala ena yotsirizidwa.
Okhakhala kuphulika kuyeretsa limaphatikizapo njira zosiyanasiyana monga ntchito mitundu yambiri ya TV injini ndi madzi kapena mphepo. The abrasives TV zimasiyanasiyana, kuchokera hulls mpunga ndi zipolopolo mtedza kuti slags zosiyanasiyana, garnet ndi zitsulo mpirawo. Chitsanzo kuphulika kukonza mchere monga staurolite, olivine, specular hematite ndi garnet. Opangidwa media ntchito kuphulika kuyeretsa monga pulasitiki, mchere TACHIMATA, galasi zobwezerezedwanso, zitsulo kuwombera, malasha slag, slag mkuwa ndi faifi tambala slag.
Kwa zaka zoposa 50, silika anali zofala kwambiri ntchito abrasive kwa abrasive kuyeretsa kuphulika, motero coining wa sandblasting akuti, monga ndalama ndiponso yosavuta kugwiritsa ntchito.
Tumizani uthenga wanu kwa ife:
