Kodi ufa woyera wa corundum umakulitsa bwanji moyo wautumiki wa zida?
Ndi chiyani chowawa kwambiri mu youmakudula ndi kuperamakampani? Sichiwonjezeko cha ngongole za magetsi kapena kuvutika kwa ntchito, koma zida zomwe zimafa mofulumira kwambiri! Mawilo opera, malamba opangira mchenga, miyala yamafuta, ma discs ogaya… anyamatawa omwe amapeza zofunika pa moyo “adzawonongeka” m’masiku oŵerengeka, ndipo m’malo mwawo ndi atsopano kuli ngati kudula nyama. Makamaka pokonza zida zolimba za mafupa - zitsulo zosapanga dzimbiri, zotsekemera zotentha kwambiri, ndi zitsulo zolimba, zidazo zimatha mwachangu kotero kuti mumakayikira moyo wanu.
Hei, abwenzi akale, lero tikambirane momwe kanthu kakang'ono kosadziwika bwino kameneka,ufa woyera wa corundum, yakhala njira yothetsera “kufutukula moyo” wa zida? sindikukokomeza. Ngati mugwiritsa ntchito bwino, si zachilendo kuwirikiza kawiri moyo wa zida, ndipo ndalama zonse ndi ndalama zenizeni!
Ndikukonzerani izo!”–Chidziwitso chamatsenga “chodzinola”
Tangoganizani: wosanjikiza wa abrasive njere pamwamba pagudumu loperandi lolunjika, ndi dzuwa amachepetsa. Panthawiyi, ngati gudumu lopukuta likugawidwa mofanana ndi ufa woyera wa corundum, iwo ali ngati "gulu losungira" lobisala.
Chomangiracho chikavala bwino pansi pa mphamvu yogaya ndi kutentha kwamphamvu, tinthu tating'ono ta ufa timakhala ndi mwayi "wowonetsa mitu yawo" ndikusintha tinthu tating'ono tosawoneka bwino tikupanganso nsonga yakuthwa!
Izi zimachepetsa kwambiri kuthamanga kwa gudumu lonse lopukuta kukhala "pansi lathyathyathya", kulola kuti gudumu lopukuta likhalebe lakuthwa kwa nthawi ndithu, mphamvu yodulirayo siiwola, ndipo kukonza bwino kumakhala kokhazikika. Malo athu ogwirira ntchito amagaya gulu lazitsulo zamphamvu kwambiri za alloy, pogwiritsa ntchito mawilo a ceramic osakaniza ndi W10 micro-ufa. Poyerekeza ndi mawilo akupera wamba, zimatengera pafupifupi 30% ntchito yochulukirapo kuti ipere isanadulidwe. Abwana akusangalala kwambiri.
Chinsinsi chogwiritsa ntchito ufa wocheperako kukulitsa moyo wagona pa "kufananiza" ndi "kugwiritsa ntchito"
Ufa wawung'ono ndi chinthu chabwino, koma si mankhwala, ndipo si chinthu chomwe chingagwiritsidwe ntchito pongowaza mwachisawawa. Ngati mukufuna kuti izi ziseweretse zamatsenga zowonjezera moyo, muyenera kulabadira:
Sankhani yoyenera "mnzako" (tinthu kukula zofananira): The tinthu kukula kwamicro powder (Nambala ya W) iyenera kufanana ndi kukula kwa tinthu tating'onoting'ono ta abrasive (tinthu tating'onoting'ono)! Ngati ili yovuta kwambiri, kudzaza ndi kukulitsa kudzakhala kosauka; ngati ili yabwino kwambiri, ikhoza kukulungidwa kwathunthu ndi chomangira ndi "kufota" ndipo sichigwira ntchito. Ulamuliro wa chala chachikulu: Ndi bwino kuti tinthu kukula kwa yaying'ono ufa kukhala pafupifupi 1/5 kuti 1/3 wa tinthu kukula kwa abrasive waukulu. Mwachitsanzo, ngati mugwiritsa ntchito 46# coarse particles, ndizoyenera kufanana ndi W20-W14 micro powder.
Phunzirani "mulingo" (chiwerengero chowonjezera): Kodi ungawonjezere ufa wochuluka bwanji? Zotsatira zochepa sizowonekera, ndipo zowonjezereka zingakhale zotsutsana, zomwe zimakhudza mphamvu ya binder kapena kupangitsa kuti gudumu lopera likhale lolimba kwambiri. Chiŵerengerochi chimadalira zoyesera ndi zochitika, ndipo nthawi zambiri zimasinthidwa mkati mwa 10% -30% ya kulemera kwake kwa abrasive. Mawilo akupera utomoni akhoza kuwonjezeredwa 20% -30%, ndi mawilo ceramic akupera zambiri 10% -20% zokwanira. Osapita molemera chifukwa cha zida zolimba!
Sankhani "bwalo lankhondo" (zida zogwiritsidwa ntchito):
Ma abrasives ophatikizidwa (mawilo opera, miyala yamafuta, mitu yopera): Iyi ndiye bwalo lalikulu lankhondo lokulitsa moyo wa micropowder! Makamaka oyenera mawilo akupera ndi zomangira utomoni ndi vitrified zomangira. Kukonzekera ndi kusakaniza ndondomeko ndiye chinsinsi chowonetsetsa kuti micropowder imabalalika mofanana.
TACHIMATA abrasives (mchenga malamba, sandpaper): Popanga mchenga malamba ndi sandpaper, kuwonjezera pang'ono micropowder (monga 5% -15% ya abrasive okwana) kuti guluu m'munsi ndi pa-glue akhoza kwambiri kusintha mphamvu yogwira a particles abrasive, kuteteza particles abrasive kugwa mu nthawi isanakwane, komanso antilogging. Ndizothandiza kwambiri popanga malamba opera bwino.
Kupera ndi kupukuta madzi / phala: Gwiritsani ntchito mwachindunjiwhite corundum micropowderkukonzekera phala lamadzimadzi kapena lopukutira kuti mutsirize kwambiri.
