Abrasive imatanthawuza kukhala ndi pamwamba kapena mawonekedwe okhwima ndipo amatha kuwononga zipangizo ndi mikangano. Atha kugwiritsidwa ntchito kufotokoza anthu, zochita, kapena zinthu monga sandpaper kapena emery.
Abrasive ndi zinthu, zomwe nthawi zambiri zimakhala mchere, zomwe zimagwiritsidwa ntchito popanga kapena kumaliza ntchito popaka zomwe zimapangitsa kuti gawo lina la ntchito liwonongeke. Ngakhale kutsirizitsa chinthu nthawi zambiri kumatanthauza kupukuta kuti chikhale chosalala, chonyezimira, ntchitoyi ingathenso kupangitsa kuti ikhale yolimba monga ma satin, matte kapena mikanda.
M’nkhaniyi, ndifotokoza tanthauzo la mawuwa, ndipo ndifotokozanso mfundo zina zosangalatsa zokhudza mawuwa.
Mu positi iyi tikambirana:
Kuwonongeka Kwambiri kwa Zida
Tikamva mawu oti "abrasive," nthawi zambiri timaganiza za chinthu chomwe chimawononga kapena kuvala mwa kukanda kapena kugaya. Atha kukhala zochita zolimbitsa thupi kapena mawu ofotokozera omwe amagwiritsidwa ntchito pofotokoza makhalidwe a munthu. Komabe, pankhani ya zida, abrasive amatanthauza chinthu chomwe chimatha kuchotsa zinthu zapamtunda pogaya kapena kusisita.
Zitsanzo za Zida Zowonongeka
Zida zonyezimira zimabwera mosiyanasiyana, kukula kwake, ndi mawonekedwe, ndipo amapangidwa pazifukwa zosiyanasiyana. Zitsanzo zina za abrasive materials ndi:
- Daimondi: Ichi ndi chinthu cholimba kwambiri chomwe chimagwiritsidwa ntchito podula ndi kupukuta malo olimba.
- Mwala Wachilengedwe: Miyala ngati mchenga ndi granite imagwiritsidwa ntchito ponolera mipeni ndi zida zina zodulira.
- Ma abrasives omangika: Awa ndi ma abrasive compounds omwe amalumikizana pamodzi kuti apange gudumu lopera. Amagwiritsidwa ntchito kwambiri popukutira ndi kunola.
- Ma Compounds: Awa ndi ma abrasive compounds omwe amagwiritsidwa ntchito pamwamba kuti akwaniritse zomwe akufuna. Nthawi zambiri amagwiritsidwa ntchito popukuta ndi kuyeretsa.
- Sandpaper: Uwu ndi mtundu wa zinthu zonyezimira zomwe zimagwiritsidwa ntchito kuchotsa zinthu zapamtunda pokwapula kapena kugaya.
Kufunika Kosankha Zinthu Zonyezimira Zoyenera
Kusankha zinthu zonyezimira bwino ndikofunikira kuti mukwaniritse zomwe mukufuna komanso kupewa kuwononga kumtunda komwe kukugwiritsidwa ntchito. Zinthu zomwe muyenera kuziganizira posankha zinthu za abrasive ndi izi:
- Chikhalidwe cha pamwamba chomwe chikugwiridwapo
- Mapeto ofunidwa
- Mtundu wa ntchito yomwe ikugwiridwa
- Nthawi ndi ndalama zogwirira ntchitoyo
Gawo Lomaliza: Kugwetsa Malupanga
Pankhani ya malupanga, gawo lomaliza lakunola ndilo kukwapula. Izi zikuphatikizapo kugwiritsa ntchito lamba wachikopa wokutidwa ndi abrasive kuti afikire m'mphepete mwa lezala. Izi zimaonedwa kuti ndizofunikira kwa malupanga a ku Japan ndipo nthawi zambiri zimagwirizanitsidwa ndi mtengo wapamwamba komanso khalidwe.
Maganizo Olakwika Pankhani ya Abrasive Materials
Mosiyana ndi zimene anthu ambiri amakhulupirira, zinthu zonyezimira siziwononga kwenikweni. Amatilola kuti tikwaniritse zosalala ndi zoyera pamtunda, ndipo zingagwiritsidwe ntchito bwino popanda kuwononga. Chofunika kwambiri ndi kusankha zinthu zomatira zoyenera pa ntchito imene muli nayo ndi kuzigwiritsa ntchito moyenera.
Zida za abrasive zimagawidwa malinga ndi mtundu wa kudula kapena kugaya zomwe zimagwiritsidwa ntchito. Ena mwa magulu omwe amadziwika kwambiri ndi awa:
- Kupera: Izi zimaphatikizapo kugwiritsa ntchito zinthu zonyezimira pochotsa zinthu pa chogwirira ntchito.
- Kupukutira: Izi zimaphatikizapo kugwiritsa ntchito zida zonyezimira kuti chiphasocho chizikhala bwino.
- Kulemekeza: Izi zimaphatikizapo kugwiritsa ntchito zida zonyezimira kuti zifewetse ndikuwongolera kulondola kwa chogwirira ntchito.
Kudziwa Luso la Abrasives: Malangizo ndi Njira
Pankhani ya abrasive zipangizo, pali zosiyanasiyana zimene mungachite. Nayi mitundu yodziwika bwino ya ma abrasives ndi ntchito zawo:
- Mafuta achilengedwe: Izi ndi zinthu monga mchenga, pumice, ndi emery. Nthawi zambiri amagwiritsidwa ntchito popanga mchenga, kupukuta, ndi kumeta.
- Synthetic abrasives: Izi zimaphatikizapo silicon carbide, aluminium oxide, ndi boron nitride. Kawirikawiri amagwiritsidwa ntchito popera, kudula, ndi kunola.
- Ma abrasives a diamondi: Awa amatengedwa kuti ndi abwino kwambiri kupukuta ndi kunola chifukwa cha kuuma kwawo kwakukulu.
Kusankha Abrasive Yabwino Pazosowa Zanu
Posankha zinthu zowononga, pali zinthu zingapo zofunika kuziganizira:
- Kuuma: Kuuma kwa zinthu zonyezimira kuyenera kukhala kwakukulu kuposa zomwe zikugwiritsidwa ntchito.
- Mawonekedwe: Maonekedwe a abrasive material angakhudze kutha ndi mphamvu ya ndondomekoyi.
- Kukula: Kukula kwa njere za abrasive kungakhudzenso kutha ndi mphamvu ya ntchitoyi.
Kugwiritsa Ntchito Zida Zonyezimira Mogwira Mtima
Nawa maupangiri ogwiritsira ntchito zonyezimira kuti muwongolere ntchito yanu:
- Gwiritsani ntchito mphamvu yoyenera: Kugwiritsa ntchito mphamvu mopitirira muyeso kungawononge zinthu zimene zikugwiritsiridwa ntchito, pamene mphamvu yochepa kwambiri sikungachotse zinthu zosafunikira.
- Ziwume: Zinthu zonyezimira nthawi zambiri zimagwiritsidwa ntchito zouma, chifukwa kuwonjezera madzi kapena zakumwa zina kumachepetsa mphamvu yake.
- Sakanizani ndikugwirizanitsa: Kuphatikiza mitundu yosiyanasiyana ya ma abrasives kungapangitse njira yogwira ntchito komanso yogwira mtima.
- Ma abrasives omangika: Izi ndi zinthu zomwe zida zotayira zimamangiriridwa kuzinthu zochirikiza, monga sandpaper kapena mawilo opera. Amagawidwa molingana ndi mtundu wa othandizira omangira omwe amagwiritsidwa ntchito.
Mbiri ya Abrasives
Kugwiritsiridwa ntchito kwa ma abrasives kunayamba kale, ndi umboni wakuti aku China amagwiritsa ntchito zipangizo zowonongeka kuti azinola ndi kupukuta zida kuyambira 3000 BC. Kugwiritsa ntchito mphamvu zamagetsi kupanga ma abrasives kudayamba chakumapeto kwa zaka za zana la 19, ndikukhazikitsidwa kwa Carborundum Company. Masiku ano, ma abrasives amagwiritsidwa ntchito m'mafakitale osiyanasiyana komanso ntchito padziko lonse lapansi.
Kutsiliza
Abrasive ndi liwu lomwe limagwiritsidwa ntchito kutanthauza chinthu chovuta komanso chosasangalatsa.
Muyenera kugwiritsa ntchito abrasive zipangizo kuchotsa zinthu pamwamba. Ndikofunikira kusankha chonyezimira chomwe chili choyenera pa ntchitoyi ndikuchigwiritsa ntchito moyenera. Chifukwa chake, musaope kufunsa bwenzi lanu la abrasive kuti akupatseni malangizo!
