Uqhushumbo oluqhumayo kunye noNgcoliseko

Ukudubula kwe-abrasive, okwakwaziwa ngokuba yi-sandblasting, yinkqubo yokulungiselela okanye yokucoca ethe yadubula imathiriyeli enokurhabula kumphezulu ophantsi koxinzelelo oluphezulu. Ngokukhula kolwazi loluntu ngokukhusela okusingqongileyo, kukho inkxalabo enokuqhushumba okuyingozi kokusingqongileyo. Eli nqaku liza kuxoxa malunga nokuba uqhushumbo oluqhumayo alulunganga na kwindalo esingqongileyo kunye nendlela abantu abanokuthintela ngayo ungcoliseko.

Kukho iintlobo ezininzi zeendaba ezirhabaxa, ezinje; isanti yesilika, iiplastiki, isilicon carbide, kunye namaso eglasi. Ezi zixhobo zeendaba ezibuhlungu zihlahlela phantsi koxinzelelo oluphezulu ngexesha lokuqhuma kwe-abrasive. Ngokuxhomekeke kuhlobo lwezixhobo ezisetyenzisiweyo, i-angle yokuqhuma, isantya soqhushumbo, kunye nezinye izinto eziqhumayo, la masuntswana anokuba ngamaqhekeza amancinci othuli aqulethe izixa ezahlukeneyo ze-silica, i-aluminium, ubhedu, kunye nezinye izinto eziyingozi. Ngelixa uqhushumbo oluqhumayo, olu thuli lunokusasazeka emoyeni. La masuntswana othuli awenzakalisi nje umzimba womntu kuphela kodwa adala nongcoliseko kwendalo. Ukukhusela abantu ekuphefumleni kula masuntswana othuli, abasebenzi kufuneka banxibe iPPE.

Amasuntswana othuli ngumthombo obalulekileyo wongcoliseko lomoya, kwaye kudala impembelelo embi kakhulu kokusingqongileyo. Ngokophando, iimpembelelo ezimbi ezithi la masuntswana othuli asasazeke emoyeni azisa kwindalo esingqongileyo ziquka: ukutshintsha imo yezulu, ukutshintsha kwemozulu, amaxesha embalela, kwanokubangela ukuba iilwandle zibe neasidi. Ngaphezu koko, ukukhutshwa kwamasuntswana othuli nako kubamba ubushushu emoyeni, kwaye kubangele impembelelo yegreenhouse.

Ngoko ke, ukuba abantu abathabathi manyathelo, impendulo yokuba ukuqhushumba okutshisayo kuyingozi kwimeko-bume nguewe. Ngethamsanqa, ukulawula la masuntswana asasazeka emoyeni kunye nokukhusela okusingqongileyo, kukho imimiselo yokuqhushumba kwe-abrasive kunye nobuchule bokulawula amasuntswana. Ngaphantsi kweendlela zokulawula i-particulate, i-particle emissions ekhutshwe ngexesha lokuqhushumba ingalawulwa kwaye inciphise umonakalo kwindalo.

Ukukhusela okusingqongileyo, zonke iinkampani kufuneka zilandele ngokungqongqo iindlela zokulawula uthuli.
