Kuganizira za Chitetezo pa Kuphulika kwa Sandblasting

Panthawi yophulika mchenga, ogwira ntchito ayenera kusamalira thanzi lawo ndi chitetezo chawo ndi ena. Chifukwa chake, kuphatikiza kuvala suti yodzitchinjiriza, kuphatikiza magalasi otetezera, zopumira, zovala zantchito, ndi zipewa zomwe zidapangidwa mwapadera ndikuwunikiridwa popanga, m'pofunikanso kuphunzira zambiri za zoopsa zomwe zingachitike pakuphulika kwa mchenga. ndi zodzitetezera ku zoopsa, kupewa kuchitika zoopsa. Nkhaniyi ikupatsani mwatsatanetsatane za zoopsa zomwe zingachitike.

Malo Ophulika Mchenga

Pamaso pa sandblasting, malo a sandblasting ayenera kuyendera. Choyamba, chotsani chiopsezo chopunthwa ndi kugwa. Muyenera kuyang'ana malo opangira mchenga kuti muwone zinthu zosafunikira zomwe zingayambitse kutsetsereka ndi kupunthwa. Kuphatikiza apo, m'pofunika kuletsa ntchito zomwe zingawononge ntchito ya wogwiritsa ntchito, monga kudya, kumwa, kapena kusuta m'dera la mchenga, chifukwa tinthu tating'onoting'ono tingayambitse matenda aakulu a kupuma ndi zoopsa zina zaumoyo.

Zida Zopangira Mchenga

Zida zopangira mchenga nthawi zambiri zimakhala ndi ma hoses, ma air compressor, mapoto ophulitsa mchenga, ndi ma nozzles. Choyamba, onani ngati zida zonse zitha kugwiritsidwa ntchito moyenera. Ngati sichoncho, zidazo ziyenera kusinthidwa nthawi yomweyo. Komanso, chofunika kwambiri, muyenera kuyang'ana ngati ma hoses ali ndi ming'alu kapena zowonongeka zina. Ngati payipi yosweka itagwiritsidwa ntchito pophulitsa mchenga, tinthu ta abrasive titha kuvulaza wogwira ntchitoyo ndi antchito ena. Ngakhale kuti palibe tinthu tating'onoting'ono ta abrasive, titha kusankha zida zowononga poizoni kuti tichepetse kuwonongeka kwa thanzi la wogwiritsa ntchito. Muyenera kusunga zosefera zopumira ndi zowunikira mpweya wa carbon monoxide nthawi zonse kuti mutsimikizire kuti malowa ali ndi mpweya wabwino kuti muchepetse chiwopsezo cha chilengedwe chomwe chikuphulika. Kuphatikiza apo, muyenera kuonetsetsa kuti zida zoteteza zilipo, zomwe zimakutetezani ku zowonongeka.

Zowononga mpweya

Kuwombera mchenga ndi njira yokonzekera pamwamba yomwe imapanga fumbi lambiri. Kutengera sing'anga yophulitsa yomwe imagwiritsidwa ntchito komanso zida zapamtunda zomwe zimavalidwa pophulitsidwa, ogwiritsa ntchito amatha kuwonetsa zowononga mpweya zosiyanasiyana, kuphatikiza barium, cadmium, zinki, mkuwa, chitsulo, chromium, aluminiyamu, faifi tambala, cobalt, crystalline silika, amorphous silika, beryllium, manganese, lead ndi arsenic. Chifukwa chake, ndikofunikira kuvala zida zodzitetezera moyenera.

Ventilation System

Ngati palibe mpweya wabwino panthawi ya mchenga, mitambo yafumbi yochuluka imapangidwa pamalo ogwirira ntchito, zomwe zimapangitsa kuti wogwiritsa ntchito asawonekere. Sizingowonjezera ngozi komanso kuchepetsa mphamvu ya mchenga wa mchenga. Choncho, m'pofunika kugwiritsa ntchito njira yopangira mpweya wabwino komanso yosamalidwa bwino kuti mukhale otetezeka komanso ogwira ntchito ogwira ntchito. Makinawa amapereka mpweya wokwanira wothandiza kupewa kuti fumbi likuchuluke m'malo otsekeredwa, kuwongolera mawonekedwe a oyendetsa, komanso kuchepetsa kuchuluka kwa zowononga mpweya.

Kuwonekera ku Magulu Okweza Amawu

Ziribe kanthu kuti ndi zipangizo ziti zomwe zimagwiritsidwa ntchito, kuphulika kwa mchenga ndi ntchito yaphokoso. Kuti mudziwe molondola mlingo wa phokoso umene wogwiritsa ntchitoyo adzawululidwe, phokoso la phokoso liyenera kuyesedwa ndi kuyerekeza ndi mulingo wowonongeka wakumva. Malinga ndi kuwonekera kwa phokoso lantchito, ntchito zonse ziyenera kuperekedwa ndi chitetezo chokwanira chakumva.
