1. Kodi maburashi abrasive ndi chiyani?
Maburashi Abrasive (Abrasive Brushes) ndi chida chapadera chopangira zinthu zakale zamwala wachilengedwe.Amapangidwa ndi waya wachitsulo chosapanga dzimbiri kapena waya wapadera wa nayiloni bulashi wokhala ndi diamondi kapena silicon carbide.
Ili ndi makulidwe osiyanasiyana ndi mawonekedwe ofananira ndi makina opera Pamanja, mzere wongopeka wopitilira ndi kupukuta, makina okonzanso pansi ndi makina opera amanja ndi zida zina.
Burashi yopukutira mwala imagwiritsa ntchito mfundo yotsuka kuti pamwamba pa mwalawo iwoneke mafunde achilengedwe kapena ming'alu yofanana ndi nyengo, ndipo nthawi yomweyo imakwaniritsa mawonekedwe a satin mercerized ndi akale pamtunda, ngati kuti wakhala akugwiritsidwa ntchito kwa mazana. kwa zaka zambiri, ndipo nthawi yomweyo kusintha ntchito yoletsa kuwononga mwala Wopanda madzi, ndikupangitsa kuti miyala yamwala ikhale yosasunthika.
2.Njira yogwiritsira ntchito mwala wopera burashi
Maburashi omwe amagwiritsidwa ntchito mu burashi yopera mwala amagawidwa mofanana ndi mchenga wa silicon carbide wokhala ndi m'mphepete lakuthwa.Pamene burashi ikanikizidwa ndikusunthira pamtunda wamwala, mafinya a burashi amapindika momasuka ndi pamwamba pa mwala wosagwirizana.Gwiritsani ntchito nsonga zakuthwa za mchenga kuyeretsa pamwamba pa miyala.Yesetsani kupukuta ndi kupukuta mozungulira, ndikuwonjezeka kwa chiwerengero cha maburashi opera, kuchepa kwapang'onopang'ono kwa mchenga wa mchenga, ndi kuchepa kwapang'onopang'ono kwa zizindikiro zopera, mpaka mwala wopukutidwa ukuwonetsa zotsatira za satin mercerizing pamene mukusunga zosagwirizana. pamwamba.
Amagawa maburashi akupera molingana ndi mawonekedwe ndi mawonekedwe:
Maburashi opera miyala amakhala ndi mawonekedwe atatu:Mtundu wa Frankfurt(mawonekedwe ansapato), mawonekedwe ozungulira, ndiMtundu wa Fickert.Pakati pawo, mtundu wa Frankfurt umagwiritsidwa ntchito pa makina opangira manja, kupukuta ndi kupukuta mizere yopangira, makina okonzanso pansi, ndi zina zotero.mtundu wozungulira umagwiritsidwa ntchito pamakina ang'onoang'ono opukutira pamanja, makina okonzanso pansi, etc.;mtundu wa Fickert umagwiritsidwa ntchito pamakina ongopera osalekeza.
Malingana ndi chiwerengero cha zinthu, pali 24 #, 36 #, 46 #, 60 #, 80 #, 120 #, 180 #, 240 #, 320 #, 400 #, 600 #, 800 #, 1000 #, 1200 # , 1500# manambala a grit awa a maburashi a diamondi kapena silicon.
Nthawi zambiri, maburashi abrasive ndi 24# 46# maburashi abrasive amagwiritsidwa ntchito kuchotsa looseness pamwamba ndi kuumba pamwamba bolodi;46 #, 60 #, 80 # amagwiritsidwa ntchito pogaya movutikira;120 #, 180 #, 240 # angagwiritsidwe ntchito poponya mwaukali;320 #, 400 # ndi finely opukutidwa, 600 # 800 # 1000 # 1200 # 1500 # ndi Premier kupukuta, kuti pamwamba mwala akhoza kukwaniritsa zotsatira mercerized.Ngati ndi nthawi yoyamba kugwiritsa ntchito maburashi abrasive, zitsanzo zosiyanasiyana ziyenera kuyesedwa ndi kusankhidwa molingana ndi mtundu wa mwala ndi zotsatira zopera zomwe ziyenera kukwaniritsidwa.
3.Kodi kusankha mwala akupera burashi ?
Burashi yabwino yopera miyala yamtengo wapatali iyenera kukhala ndi izi:
●Waya wa burashi sayenera kugwa panthawi yogwira ntchito
● Mawaya omangira m'munsi mwa burashi ayenera kupangidwa ndi zitsulo zosapanga dzimbiri zosapanga dzimbiri kuti zisawonongeke.
● Waya wabulashi uyenera kupindika mozungulira ngati wavy.
● Mchenga wonyezimira mu waya wa burashi usagwe chifukwa cha kupindika kwa waya wa burashi.
● Utali wokwanira waburashi ndi kachulukidwe.
● Ulusi wa maburashi uyenera kukhala wolimba kwambiri komanso wolimba m'malo achinyezi.
● Waya wopindika uyenera kupindika bwino.
● Waya wabulashi uyenera kukhala wosamva kukwapulidwa.
4. Mfundo ntchito maburashi miyala abrasive
Stone akupera burashi ayenera kulabadira mfundo zotsatirazi pakupanga ndi processing ndondomeko:
1. Madzi ozizira ayenera kuwonjezeredwa panthawi yopera ndi kupukuta.Pewani mawaya a burashi kuti asapunduke chifukwa cha kutentha kwambiri komwe kumapangidwa pamene waya wa burashi ukupukutira pa liwiro lalikulu.
2.Ndi ndondomeko yogwirira ntchito yachitsanzo cha abrasive burashi kuchokera ku coarse kupita ku chabwino, kukakamiza kumagwira pamutu wopera pa burashi kuyeneranso kukhala kuchokera ku zazikulu mpaka zazing'ono.
3.Kudumpha manambala kuyenera kukhala koyenera.Kuchepetsa kwakukulu kwa maulalo apakatikati kungakhudze momwe akupera, koma zitha kukulitsa mtengo wopanga.
4. Gwiritsani ntchito burashi yawaya ngati kuli kotheka.Kugwiritsiridwa ntchito kwa maburashi a waya poyambirira kungachepetse kuvala kwa mawaya abrasive pa mbale yaukali ndikutalikitsa moyo wautumiki wa maburashi abrasive.
