Kodi kusankha zida kupukuta mu konkire pansi kupukuta?

Zida zopukutira konkriti makamaka zimaphatikizapo izi:
PCD ❖ kuyanika kuchotsa zimbale, amene ntchito kuchotsa zokutira pa konkire pansi, ndi zofunika pamene pali wandiweyani ❖ kuyanika ngati epoxy pansi.
Diamondi akupera zimbale, kawirikawiri ntchito konkire pansi kusanja ndi akale pansi kukonzanso.
Mapadi opukutira a dayamondi, nthawi zambiri amatanthauza mapepala opukutira a utomoni okhala ndi makulidwe a 5mm kapena kupitilira apo, omwe amagwiritsidwa ntchito poyala pansi konkire, kugaya ndi kupukuta.
Padi yopukutira ya diamondi yopyapyala, nthawi zambiri imatanthawuza zoyala zopukutira za utomoni wokhala ndi makulidwe osakwana 5mm, omwe amagwiritsidwa ntchito kupukuta bwino.
Siponji zopukutira, nthawi zambiri zimagwiritsa ntchito ulusi wopangidwa ndi anthu, ubweya kapena ubweya wa nyama ngati maziko/zothandizira komanso zokhala ndi ma diamondi ndi ma abrasives opopera ndi kumizidwa mkati mwa zinthu zoyambira.
Pali mitundu yambiri ya zida zopukutira zopukutira konkriti pansi, momwe mungasankhire ndikuzigwiritsa ntchito?
Kuti tisankhe ndikugwiritsa ntchito zida zopukutira moyenera, choyamba tiyenera kumvetsetsa mayina awa:
Kusalala kwa pansi
Pazipinda zomwe zidapondedwa kapena zowongoleredwa pamanja kapena zakale zomwe ndi zotayirira komanso zowonongeka kwambiri, m'pofunika kusanjikiza kapena kuchotsa wosanjikiza wotayirira.Tiyenera kugwiritsa ntchito chopukusira champhamvu kwambiri ndi ma discs amwano a diamondi kuti tiwongolere pansi tisanapukutire.Pazipinda zodziyimira pawokha kapena zapansi zomwe zowongoleredwa ndi makina opangira mphamvu, titha kupeza pansi zokongola zopukutidwa ndi zopukutira za resin bond zokha.
Kuuma kwa pansi
Simenti yomwe imagwiritsidwa ntchito kutsanulira pansi konkire imayimiridwa ndi nambala, monga C20, C25, C30 ndi zina zomwe timakambirana nthawi zambiri.Nthawi zambiri, kuchuluka kwa konkire kumakhala kolimba kwambiri, koma chifukwa cha zinthu zosiyanasiyana, kuchuluka kwa simenti ndi kuuma kwa pansi nthawi zambiri sikufanana.Kuuma kwa konkriti pansi nthawi zambiri kumawonetsedwa ndi kuuma kwa Mohs.Mohs kuuma kwa konkire pansi nthawi zambiri kumakhala pakati pa 3 ndi 5. Pamalo ogwirira ntchito yomanga, tingagwiritse ntchito zina m'malo mwa Mohs hardness tester kuti tidziwe kuuma kwa pansi.Ngati titha kupeza mano kapena zokopa pansi ndi misomali yachitsulo kapena makiyi ndiye titha kunena kuti kulimba kwa konkriti ndikochepera 5, apo ayi, kuuma kumaposa 5.
Ubwino ndi liwiro la chopukusira
Makina opera apansi nthawi zambiri amagawidwa kukhala opepuka, kukula kwapakatikati ndi zopukutira zolemetsa.Ma Heavy duty grinders ali ndi mphamvu zambiri kotero kuti amagwira ntchito bwino kwambiri.M'mapulogalamu enieni, zikafika pa zogaya, sizokulirapo kuposa zabwinoko.Ngakhale kuti mphamvu zogaya za heavy duty grinders ndizokwera kwambiri, zimathanso kuyambitsa kugaya mochulukira kotero kuonjezera mtengo womanga.Makontrakitala odziwa bwino adzasintha liwiro lozungulira, liwiro loyenda, kuchuluka kwa ma discs ogaya komanso kulemera kwa makina kuti achepetse mtengo womanga ndikuwongolera magwiridwe antchito.
Mtundu ndi kukula kwa zida zopukutira
Zida zomwe zimagwiritsidwa ntchito kwambiri popukutira konkire pansi ndi ma PCD akupera ma disc, ma discs opera achitsulo ndi mapepala opukutira a resin bond.PCD akupera zimbale ntchito kuchotsa zokutira wandiweyani pansi pamwamba, zitsulo chomangira akupera zimbale ntchito pokonzekera pansi pamwamba ndi akupera akhakula, utomoni chomangira kupukuta ziyangoyango ntchito pa ukupera zabwino ndi kupukuta.Nambala ya Grit ya zida zopukutira imatanthawuza kukula kwa tinthu tating'ono ta diamondi zomwe zili mu zidazo.M'munsimu nambala ya grit, ndi kukula kwa tinthu ta diamondi.Palibe grit nambala ya PCD pogaya zimbale, koma ali ndi mayendedwe, wotchipa ndi counterclockwise.Tiyenera kumvera malangizo ake tikamagwiritsa ntchito PCD.Chitsulo chomangira akupera zimbale zambiri kubwera ndi grits 30 #, 50 #, 100 #, 200 #, 400 #.Nthawi zambiri timadziwa kuti ndi grit yoti tiyambe molingana ndi momwe zilili pansi.Mwachitsanzo, ngati pansi si bwino kapena pamwamba ndi lotayirira, tingafunike kuyamba ndi 30 # zitsulo chomangira akupera zimbale kuchotsa lotayirira pamwamba ndi kusanja pansi.Ngati tikufuna kuwulula aggregates, 50# kapena 100# zitsulo chomangira akupera zimbale zofunika.Ma resin bond polishing pads amabwera ndi grits kuchokera ku 50 # mpaka 3000 #, ma grits osiyanasiyana amasiyanitsidwa ndi mitundu yosiyanasiyana ya Velcro.Pali zopalasa zokhuthala komanso zopatulira zopyapyala.Zochindikira zopukutira ndi zolimba zoyenera kukula kwapakatikati komanso zopukutira zolemetsa.Mapadi owonda opukutira ndi osinthika oyenera ma grinders opepuka opukutira bwino.
Mukamvetsetsa zomwe zili pamwambazi 4 zomwe zimakhudza kusankha kwathu mapepala opukutira.Ndikukhulupirira kuti mukudziwa kale momwe mungasankhire zida zoyenera zopukutira pa ntchito yanu yopukuta konkriti.
