Ukuthi Izihlalo Ze Diamond Saw Ezingenamthubi Ziphepha Kanjani Ukukhazimula Kwe-Silica Ngempela

Imithombo Yokulungisa Ukukhazimula Kuzihlalo Ze Diamond Ezingenamthubi

Amabhuladi abachaphazela angapheli kakhulu ayethulwa ngokuphelele kakhulu kusilica njengoba anesistimi esifakwayo esenzima ukuthatha lezi ziphazamiso zancane lapho zavela ng during cutting operations. Ifomu yezinkomba zegolide zebhuladi yazelwe ngokucophelela ukuze lapho ibhuladi ilotsha, iyithulule kusuka kumkhawulo wokugcina ngokusebenza kwesithwebula. Lezi bhuladi zinezincwadi eziningi (ezahlukene kakhulu nge-0.125 inches kuphela) nezincwadi ezigcwele kangcono ukuze kungavunyelwe ukuhamba okuningi kakhulu komfanekiso. Umdla wokucinga izinyathelo zokugcina kubonisa ukuthi lezi zici zingasusa amanzi atholakala engqesheni yezikhathi ezimbili ngokulingana nobude bamaqondo ahlelekile. Ngaphezu koko, indimana yonke yokuba yenzelwe ngokuchaphazela ikwenza izinkinga eziphakeme ekulawuleni ngoba iyohlaza inhloso nezidingo zonke ezitholakala kuze kube khona emacaleni akhethekile endaweni esivumela kuzodlala lapho umuntu angaphansi.

Ukutholakala kwebhlayidi: Turbo-rim, isithunzi, nasekelaphaya ukuze kube nephepha encane

Izandla zomkhawulo weziphaziyana ezintathu zabelana nokugcina okuhle uma zihlotshaniswa nezinhlelo zokugcina ziphaziyana efanayo:

• Ibhleyidi ze-turbo-rim : Amancane amakhophothi ayekela ukukhathazeka nokushisa, akunciphisa izinto ezilayikayo ngaphandle komsindleko wokugcina
• Ibhleyidi zesithunzi : Izigqoko ezide phakathi kwemithunzi khipha izinkunkuma ngaphambi kokwanelwa—yoqobo kubonke bethile nasekhalini
• Ibhleyidi esekelaphaya : Isenzo esisuke sokugcina sibangela izinto eziphezulu, ezihlawulwa ngendlela efanelekile ngamathekwane ebhambu etholakalayo

Ibhleyidi enezinto ezincane (4–10) nesilazi esodwa ngelaseri sibonisa ukungena okuncane kabangaki kweziphaziyana zesiSilica (30–50%) emazingeni ekhombisa ukufanekisa ku-OSHA. Ukutholakala kwezinye nezokugcina ngamanzi nezokudibanisa kusivacuum kusivumela ukufanekisa kwezimali futhi kujikeleze ukugcina kweziphaziyana ngexesha lokusebenza.

Izinhlelo Zokugcina Ngamanzi: Ukujikeleza Ukugcina Kweziphaziyana Ngokulahla Ngamanzi

Indlela lezinhlobo zokusebenza kwamanzi kusungula umoya we-silica futhi kuyilandela izinhlobo zika-OSHA

Ukukhulula kwezimali ekususweni kwemifula yokusebenza kakhulu ngokuvikela imifula yezilika ngoba ikwakhiwa inqanawa yamacebo amancane njengomsholo uma kukhona umfula ombandakanya ukudla. Ize izahluko zibonisa ukuthi le ndlela ibekwe ubungakanani bomphumela wezimali eziphazinyayo phakathi kwama-85 ne-90 iphesenti kunzima ezindaweni ezenziwa ngendlela epholile. Futhi lokhu kubeka ubungakanani kube khona kubaluleke kakhulu ukuze kuqhutshelwe kwi-OSHA, eyesetha indawo engeze 50 mikrogramu ngamethe cubed emuva kwemizuzwana eyishumi nanesikhombisa. Umfula unakekela indima eyodwa esibaluleke - ukugcina iziklasi ze-diamond zibe libilisi kusuku oluphelele. Lokhu kugcinwa kwabalisa kuvikela izilika ukuthi sizange sihlukanwe kumacebo amancane ahlelekile okwenzeka abantu bafuna, futhi kuyakha iziklasi zibe namandla ngoba azange azange asebenziswe kakhulu. Ukuze kuphumelele kakhulu kulezi zinhlelo, abasebenzisi kufuneka bacinde umfanekiso wamaphoyinti phakathi kuka-65 no-75 degrees Fahrenheit. Amaphoyinti angaphandle kwaleli xesha ayikwazi ukukhuphula imifula ngokuhambisana noma kungaba yinkinga kumzimba okusebenziwa ngokushesha kokuguquka komfanekiso.

Izisawu ezihlotshanisiweyo ngaphandle kwezixhobo zokugaya: Ukuh comparisona kokusebenza, ukuthwasa nokuphila

Izisawu ezihlotshanisiweyo njalo zizodwa zinezigaba zezibhamu ezenziwe ngokufanele kwaye iindawo zokugaya eziphulwa ngokucophelela. Le ngxaki zisenza isathuthi siphilwe ngokuchanekileyo kwicala, okanye kufakela kakhulu kunye ne-90% efficiency. Ukugcinwa kwegunya elithunyelweyo kwenziwa ngokufinyezwa kuyakha ngempilo emsebenzini. Kodwa, le mikhumbi izodwa ibalulekile kwaye kudinga iintambo ezifanelekileyo zokugaya oko kuyakha ikhishiselwa. Abantu abane zixhobo ezisebenzayo, izixhobo zokuhlanjulwa zinokuba yindlela engcono ngoba zingajongana nezixhobo ezikhoyo. Kanti, kukho na intlanga lapha, umsebenzisi kufuneka atshintshise ngokujonga inani lokugaya kwaye alungise i-nozzles ngokudlulula uma ufuna indlela iphinde yenzeke kakuhle. Ngoko xa ukhetha phakathi kwezinto, abantu kufuneka baphelele okubalulekile kangakanani - ubomi bomthwalo okanye ukusebenza okomthwalo.

Izinhlelo ebasekwa amanzi azivimela izinkinga zokugcina okuthintana nokukhanya kuzinhlelo zokucula, njengoba zihlanganisa ukunciphisa isilika ngendlela etholakala nge-OSHA.

Ukulawula kwezibungu: Ukuhlakanipha kwe-HEPA kanye Nokuvikela Kwisithunzi (LEV)

Amavakhesi we-H-class nezinhlelo zokuhlakanipha isilika ezinezici ephakeme (≥99.97% @ 0.3 µm)

Amavakwala okuhaya weh-klasi H kuyisisekelo ekuphileni ngokwanele ukuqasha isilika. Loo zinhlayiya zingakweza izinto ezingaphansi kuka microns 0.3 ngokungenani nge-99.97%, lokhu kulingana nezimiso ze-OSHA Table 1 yokulawula ukuthintana no-silica crystaline uma kudonywa ngeblade zenziwe ngaphandle kweqhasha. Isistemu sokulahla siyasemba futhi: kukhona amafilter aphambili ezinto ezikhulu, emva koko i-HEPA filter ekhethiweyo eyamukela izinto ezincane zokuthi aziphumele, kunye nobumbano obugcwele obugcina konke kuqukethe ngodaba olungaphansi. Amavakwala asebenziswa kakhulu akusizo lapha ngoba kuhlukile ukuthatha inqwelo uma imfilithri ihlanjuluka ngale qhasha encane. Kukhona okukhulu kwezinhlayiya zeH-class zazinzima ngendlela yokucula yomthwalo wemfilithri, ngakho abasebenzi bangelanga ukumisa umsebenzi phakathi kokusebenza ukuthinta ikonkreti noma ukusebenzisa itile.

Amabhokisi okugcwele kanye nokuhlanganisa kuka LEV: Uyisebenzisa ubungako bokuvulekiso (>100 fpm) kumxhumba wexhambo

Ukukhuseleka kahle kwezimali ngokusebenzisa izikhwama zomoya kuyaphila kakhulu kuze kube nesakhiwo esihle esikhuthazi umoya wasekhanda lapho kudingeka kakhulu. Kumaqoshiso we-diamond blade, izigaba ezakhiwe ngokuthi zenze izindawo ephathelene ngokuthile ezigcina umoya ukuxhumana ngaphezu kwezintshontsho ezingu-100 ngeminithi yomjani ngemizuzwana ekugcineni kokuphindaphindi. Kunezici eziningi ezibaluleke kakhulu ekwenzekeni kakhulu: amashela azisetshenzisayo angaphezu kwemilimeteri ethathu ayivikele umoya ukuthi awafe, iziphephe ezinzima ezifaka izinyanga ezimbili, nezinkamba ezincane ezingavimbi okubona kuzobuya abasebenzi. Uma zixhunywe kumasebenta Local Exhaust Ventilation, lezo zonke izinto zisebenza njengoba zize zenza izinhlobo zomoya ezibambe izindlela zezimali ukuze zingafuni emoyeni abantu abaphuma khona. Kubalulekile futhi ukuthi usayine isandla sokudluliswa kwezimali—kudingeka sibe nzima kakhulu ngemilimeteri engu-35—futhi ukugcina ukuthembeka kancane kakhulu kugcina ubude bomoya ngempela. Ukulungiswa kwezimali ngokushesha ngokusebenzisa i-anemometer kusincoma konke kusebenza kanjalo, futhi izixhumanisi zokugcinwa kwesitshalo zibanza uma kudingeka kucindezelwe. Lezi zombuso zombilo ziyagcina kancane kakhulu izimali ezingu-95% ze-silica ngaphandle kokuphakama kwazo.

Ukufakela Izinhlelo Zokukhinchisa Uthubi Kusimilile Kuthuli Nekhabhini

Ukubala iziklambi zokugcina ngamathuba angaphakathi amancane okuthwasa ukuthwasa kwezikhombisi ze-diamond ezingenamthubi

Abakhethi be-diamond blade abanezinhlelo zomthwalo ongenhla ezifakwe khona kuyisibonelo esihle kakhulu sokuphatha umoya ngaphandle kwenye. Inhlelo yomthwalo iyilwa ngokudlulisa kumqondo wesithixo, ngakho akudingeki ukuba kube nenkumbulo yokuthanda inhlamvu engaqondeni futhi ibone 15-20 imizuzu yokusungula ngasinye isikhathi. Okwenzela ukuthi lezi zinhlelo ziphumelele kakhulu kukuthi inhlelo yomthwalo iqale ukusebenza nganoma iluphi ilanga, kuvikelwe umoya wasekuhlaleni. Ukuze uphumelele kakhulu nalesi sizathu, qiniseka ukuthi igova ligcwalise ngendlela efanelekileyo noma yikuphi usayizi lwelanga owusebenzisa (abancane kangaka bahlala phakathi kwe-4 inci kuya ku-14 inci) futhi ujonge ukuthi inhlelo yomthwalo ikwazi ukuhambisa okungenani amacala angama-80 ngeminithi. Lezi zixhobo ziyakhola izinkomba ngokuthi zilahlekelwe kakhulu futhi zisungele ngokushesha, kodwa gqogqisela ukuthi zingabeka phakathi kwe-85% ne-92% yezipowuda zomoya. Kuzintonga eziphansi noma emakhaya apho abasebenzi bangasebephinde bakhokelele ngemini, kubaluleke kakhulu ukuthi kube nenhlelo eyengeziwe yokuphepha njengoko kuyindlela enhle yokukhipha umoya noma ukulunga okuphazanyayo kwezimali. Ungalibali ukucula lezi zimvumo uma ngoweSonto ngasinye futhi ujongcebe konke okugcina. Ukulungisa konke kuyakuhlala kuchaza ukuthi umoya uyahamba kahle futhi kunciphise izidingo zokuphepha ngokuphindaphindile.
