Kodi ufa woyera wa corundum umawonjezera bwanji moyo wa zida?
Ndi chiyani chomwe chimapweteka kwambiri mukamaumakudula ndi kupukusamafakitale? Sikuti ndi kukwera kwa mabilu amagetsi kapena kuvutika kwa ntchito, koma zida zomwe zimafa mwachangu kwambiri! Kupera mawilo, malamba opukutira, miyala yamafuta, ma disc opukutira ... anthu awa omwe amapeza ndalama "adzawonongeka" m'masiku ochepa, ndipo kuwasintha ndi atsopano kuli ngati kudula nyama. Makamaka pokonza zinthu zolimba za mafupa - chitsulo chosapanga dzimbiri, zitsulo zotentha kwambiri, ndi chitsulo cholimba, zidazo zimatha msanga kwambiri kotero kuti mumakayikira moyo wanu.
Hei, abwenzi akale, lero tiyeni tikambirane za momwe kamwana kakang'ono kosadziwika bwino aka,ufa woyera wa corundum, yakhala njira yothetsera "kutalikitsa moyo" wa zida? Sindikunena mopitirira muyeso. Ngati mugwiritsa ntchito bwino, si zachilendo kuwirikiza kawiri moyo wa zida, ndipo ndalama zomwe mumasunga zonse ndi ndalama zenizeni!
"Blunt? Ndikukonzerani!"–Chowonjezera chamatsenga "chodzinola"
Tangoganizirani: wosanjikiza wa tinthu tomwe timayabwa pamwamba pagudumu lopukusirayaphwanyika, ndipo mphamvu yake imachepa. Panthawiyi, ngati kapangidwe ka gudumu lopukusira kagawidwa mofanana ndi ufa woyera wa corundum, amakhala ngati "gulu losungira" lobisala.
Pamene chomangiracho chagwiritsidwa ntchito bwino pogwiritsa ntchito mphamvu yopukutira ndi kutentha kokangana, tinthu tating'onoting'ono ta ufa timeneti timakhala ndi mwayi "wowonetsa mitu yawo" ndikusintha tinthu tating'onoting'ono tomwe tili topyapyala kuti tipangenso m'mphepete mwakuya!
Izi zimachepetsa kwambiri liwiro la pamwamba pa gudumu lonse lopera kukhala "lathyathyathya pansi", zomwe zimathandiza kuti gudumu lopera likhale lolimba kwa nthawi ndithu, mphamvu yodula siiwola, ndipo magwiridwe antchito ake ndi okhazikika. Malo athu ogwirira ntchito amapera gulu la mipiringidzo ya alloy yolimba kwambiri, pogwiritsa ntchito magudumu opera a ceramic osakanikirana ndi ufa wa W10 micro-powder. Poyerekeza ndi magudumu wamba opera, zimafunika ntchito yowonjezera pafupifupi 30% kuti ipere isanadulidwe. Bwanayo ndi wokondwa kwambiri.
Chinsinsi chogwiritsa ntchito ufa wa micro-powder kuti ukhale ndi moyo wautali chili mu "kufananiza" ndi "kugwiritsa ntchito"
Ufa wa micro-ufa ndi wabwino, koma si mankhwala othana ndi vuto lililonse, ndipo si chinthu chomwe chingagwiritsidwe ntchito pongowaza mwachisawawa. Ngati mukufuna kuti ukhale ndi mphamvu yotalikitsa moyo, muyenera kusamala ndi izi:
Sankhani "mnzanu" woyenera (kufanana ndi kukula kwa tinthu): Kukula kwa tinthu tating'onoting'ono taufa wochepa (Nambala ya W) iyenera kufanana ndi kukula kwa tinthu tating'onoting'ono ta chinthu chachikulu chokwapula (tinthu tating'onoting'ono)! Ngati ndi chokwapula kwambiri, mphamvu yodzaza ndi kukulitsa idzakhala yofooka; ngati ndi chopyapyala kwambiri, chingakulungidwe kwathunthu ndi chomangira ndi "kupumidwa" ndipo sichingagwire ntchito. Lamulo la chala chachikulu: Ndibwino kuti kukula kwa tinthu tating'onoting'ono ta ufa wa micro kukhala pafupifupi 1/5 mpaka 1/3 ya kukula kwa tinthu tating'onoting'ono ta chinthu chachikulu chokwapula. Mwachitsanzo, ngati mugwiritsa ntchito tinthu tating'onoting'ono ta 46#, ndibwino kwambiri kufananiza ufa wa micro wa W20-W14.
Dziwani bwino "mlingo" (chiŵerengero chowonjezera): Kodi ufa wochuluka bwanji wowonjezera? Palibe zotsatira zambiri zomwe zimawonekera, ndipo kuchuluka kwambiri kungakhale kopanda phindu, kukhudza mphamvu ya chogwirira kapena kupangitsa gudumu lopera kukhala lolimba kwambiri. Chiŵerengerochi chimadalira zoyeserera ndi zomwe zachitika, ndipo nthawi zambiri chimasinthidwa mkati mwa 10%-30% ya kulemera konse kwa abrasive. Mawilo opera a resin amatha kuwonjezeredwa ku 20%-30%, ndipo mawilo opera a ceramic nthawi zambiri amakhala 10%-20% okwanira. Musamalemere chifukwa cha zinthu zolimba!
Sankhani "bwalo lankhondo" (zida zoyenera):
Zokometsera zosakaniza (mawilo opukutira, miyala yamafuta, mitu yopukutira): Iyi ndi malo omenyera nkhondo akuluakulu owonjezera moyo wa ufa wa micropowder! Makamaka oyenera mawilo opukutira okhala ndi ma resin bond ndi ma vitrified bond. Fomula ndi njira yosakanizira ndizofunikira kwambiri kuti ufa wa micropowder ugawanike mofanana.
Zomatira zophimbidwa (malamba amchenga, sandpaper): Mukamapanga malamba amchenga ndi sandpaper, kuwonjezera ufa wochepa (monga 5%-15% ya zonse zomatira) ku guluu woyambira ndi guluu wopitirira muyeso kungathandize kwambiri kugwirira tinthu tomatira, kuteteza tinthu tomatira kuti tisagwe msanga, komanso kumathandizanso kuti tisatseke. Ndi yothandiza kwambiri popanga malamba opukutira molondola.
Kupera ndi kupukuta madzi/phala: Gwiritsani ntchito mwachindunjiufa woyera wa corundum micropowderkukonzekera phala lamadzimadzi lopukutira kapena phala lopukuta kuti limalizidwe bwino kwambiri. Tinthu tating'onoting'ono kwambiri komanso ufa wochepa kwambiri zimatha kukhala ndi malo ofanana kwambiri komanso osawonongeka kwambiri, ndipo chidacho (polishing pad/wheel) chimawonongeka pang'onopang'ono kwambiri.
