Ukusika Okumanzi vs Ukusika Okwomile Ukhonkolo: Ingabe Ukusika Okwomile Kushesha Ngempela?

Buza amaqembu amabili okusika ukhonkolo ukuthi ukusika okumanzi noma okomile kuyashesha yini futhi ungathola izimpendulo ezimbili ezihlukene ngaphambi kokuba kuqalwe isaha. Elinye iqembu lizokhomba ukuthi ukusika okomile akudingi ipayipi, ithangi lamanzi kanye nokuhlanza i-slurry. Elinye lizothi uma ukusika sekude ngokwanele, ukuma ukuze kuphole i-blade akuyona indlela yokukhiqiza.

Kokubili kungaba okulungile.

Uma uqhathanisa ukusika ukhonkolo okumanzi nokwomile , iphutha liwukukala isivinini kuphela kusukela ngesikhathi i-blade ithinta i-slab. Endaweni, iwashi liqala kusenesikhathi bese lima kamuva. Ukusetha, isikhathi sokusika, ukuphumula kokupholisa, ukulawula uthuli kanye nokuhlanza konke kubalwa.

Ukusika okomile kuvame ukushesha ukukulungiselela. Nokho, ukusika okumanzi kungashesha uma ukusika okuqhubekayo kuqala. I-Hilti ithi i-DCH 300-X kagesi yayo isetshenziswa njenge-cutter. ingafinyelela ukusika okumanzi cishe ngo -30% ngokushesha kunokusika okomile uma isetshenziswa nekhithi yayo yamanzi, kuyilapho elinye ikhasi lobuchwepheshe le-Hilti likhomba ukusika okumanzi okusheshayo okufika ku-50% kwepulatifomu efanayo yokusika. Lezi yizibalo zomshini othize kunokuba kube umthetho wemboni jikelele, kodwa ziveza iphuzu elilodwa ngokusobala kakhulu: ukususa amanzi akwenzi umsebenzi usheshe ngokuzenzakalelayo.

Ingabe Ukusika Ukhonkolo Owomile Kuyashesha Ngempela?

Uma kunqunywa kafushane, ukhonkolo owomile unenzuzo yangempela. Kunezinto ezimbalwa okufanele zihlelwe, futhi umqhubi akadingi ukucabanga ngokuthi amanzi avelaphi noma ukuthi i-slurry izoya kuphi ngemva kwalokho. Emsebenzini wokuvuselela, ikakhulukazi ngaphakathi endlini, lokho kulula kungabaluleka ngaphezu kokucindezela isivinini esincane sokusika kusuka ensikeni.

I-Husqvarna ikhomba imisebenzi esheshayo, ukulungiswa kwangaphakathi kanye nezindawo lapho umswakama ungabangela khona umonakalo noma ukuphazamiseka njengezimo lapho ukusika okomile kungaba nomqondo.

Ukushintshana kuvela lapho umsebenzi uyeka ukushesha. Ama-blade edayimane okusika okomile kufanele aphathe ukushisa ngaphandle kokupholisa amanzi okuqhubekayo, ngakho-ke amaningi asetshenziswa ngezikhathi ezithile kunokuba acindezelwe ekusikeni okude ngaphandle kokuphumula. I-Concrete Network iphawula ukuthi ama-blade omile avame ukuhlotshaniswa nama-handheld saw kanye nomsebenzi oqhubekayo , kuyilapho ama-blade amanzi evame ukusetshenziswa kuma-walk-back saw ukuze kusikwe ngokujulile nangokuqhubekayo.

Yingakho umbuzo othi “Yimuphi oqala ngokushesha?” ungewona umbuzo owusizo kakhulu.

Umbuzo ongcono uwukuthi: iyiphi indlela eqeda wonke umsebenzi ngokushesha?

I-dry saw ingase inqume ngemizuzu embalwa nje ifikile. Uma-ke idinga ukumiswa okwengeziwe kokulawula ukushisa, leyo nzuzo yokuqala inganyamalala ngokushesha okukhulu.

Yini Amanzi Ayenzayo Ngempela E-Blade?

Amanzi avame ukuchazwa njengendlela yokulawula uthuli, okuyiqiniso, kodwa lokho kuyingxenye nje yendaba.

Endaweni yokusika, amanzi asiza ukulawula izinga lokushisa kwe-blade futhi athwale izinhlayiya ezincane azisuse e-kerf. Ngokwezwi elingokoqobo, lokho kusho ukuthi i-blade ingasebenza ngokuqhubekayo esikhundleni sokwakha ukushisa bese ilinda ukuthi kuphole. Kumuntu osebenza nge-slab ende, lezo ziphazamiso zibalulekile. Ukuphumula okuncane okuhlanu akuvamile ukuzwakala kuyisimanga, kodwa ekupheleni kweshifti kuba nomkhuba wokuba yizindleko zangempela zabasebenzi.

Ukujula kokusika nakho kushintsha isinqumo. Isiqondiso sobuchwepheshe se-Home Depot sokusika amanzi Ukusika okumanzi kubhala ukusika okumanzi njengokufanelekile kukhonkrithi eqinisiwe, ukusika okujulile kokunwebeka kanye nezinto zokwakha ezingaphezu kwamasentimitha angu-1.5 ubukhulu , kuyilapho futhi kuhlanganisa amasaha amanzi nokusika okude okungaphazanyiswa. Leso sibalo esingamasentimitha angu-1.5 siwusizo njengereferensi ewusizo, kodwa akuyona umkhawulo wobunjiniyela ojwayelekile. Umthamo wangempela wokusika usancike kububanzi be-blade, amandla esaha, imininingwane ye-blade kanye nomklamo womshini.

Indlela elula yokucabanga ngayo yile: lapho i-blade isebenza kanzima isikhathi eside, kuba yilapho ukupholisa kuba yigugu kakhulu.

Ingakanani Uthuli Lwe-Silica Olungancishiswa Ukusika Okumanzi?

Yilapho ukuqhathanisa kuba khona okuncane kakhulu ngokwemibono.

A isifundo sensimu esigcinwe yi-CDC/NIOSH bahlole ukusika okumanzi nokomile kwepayipi likakhonkolo eliqinisiwe futhi baqoqa amasampula othuli oluphefumulayo angu-178 . Ngesikhathi sokusika okomile, isilinganiso sothuli oluphefumulayo oluphakathi sifinyelele ku -14.396 mg/m³ , okuphindwe izikhathi ezingaphezu kweshumi kunokugxila okulinganiswe ngaphansi kwezimo ezimbili zokulawula amanzi. Ku -79 kufaniswe ukuqhathanisa okumanzi nokomile kusetshenziswa i-worker kanye ne-saw blade efanayo, ukusika okumanzi kunciphise ukugxila kothuli oluphefumulayo cishe ngo- 85% .

Lokho akusho ukuthi yonke i-wet saw izonciphisa uthuli ngo-85%. Ingxube yekhonkrithi, uhlobo lwe-blade, indlela yokusebenza, ukuhamba komoya kanye nokulethwa kwamanzi konke kushintsha umphumela. Inani locwaningo akulona isithembiso sephesenti elilodwa lomlingo. Kuwubufakazi obucacile bokuthi amanzi asetshenziswa endaweni yokusika angenza umehluko omkhulu othulini oluphefumulayo oluhamba emoyeni.

Ngomsebenzi wokwakha wase-US, I-OSHA ibeka umkhawulo wokuvezwa ovunyelwe we-silica ekristali ephefumulayo ku -50 μg/m³ njengesilinganiso esilinganiselwe isikhathi samahora angu-8 . Ithebula le-OSHA 1 libuye licacise izinhlelo ezihlanganisiwe zokulethwa kwamanzi eziqhubeka nokunikeza amanzi ensikeni yemisebenzi eminingana yokusika isarha emboziwe.

Lokho kubeka uthuli lwe-silica lokusika ukhonkolo esigabeni esihlukile kunesiphithiphithi esivamile sendawo. Akukhona nje ukugcina phansi kuhlanzekile. Kumayelana nokulawula ukuchayeka.

Ukusika Okumanzi vs Ukusika Okwomile Ukhonkolo: Indlela ngayinye isebenza kanjani kangcono?

Ayikho indlela efanele ukunqoba zonke izimpikiswano. Isayithi livame ukunquma.
