Ukukhetha i-blade yedayimani akukokukhetha nje ububanzi obufanelekileyo nokuthembela ukuba isarha iya kukuxolela. I-blade kufuneka ihambelane nezinto ezisetyenzisiweyo, isarha, ubunzulu bokusika kunye neemeko zomsebenzi. Ikhonkrithi, i-asphalt kunye ne-slabs eziqinisiweyo zonke zinokubonakala ngathi "zizinto eziqinileyo" xa zikude, kodwa kwi-blade yedayimani ziziphatha ngendlela eyahlukileyo kakhulu.
Umthetho osisiseko ulula: izinto eziqinileyo zihlala zifuna ikhonkco elithambileyo, ngelixa izinto ezithambileyo nezirhabaxa zifuna ikhonkco eliqinileyo. I-Norton Abrasives ichaza ukukhethwa kwebhondi yeblade yedayimani ngengqiqo efanayo ye-opposite-bond: ii-hard bonds zifanela izinto ezithambileyo ezirhabaxa ezifana ne-asphalt, ngelixa ii-soft bonds zifanela ikhonkrithi eqinileyo. Ekuqaleni ivakala ngathi ibuyela umva, kodwa kuyavakala xa ukhumbula ukuba i-metal bond kufuneka iguge ngesantya esifanelekileyo ukuze iveze iidayimani ezintsha.
Umthetho okhawulezayo: khetha i-blade ngokwezinto ezisetyenzisiweyo kuqala, uze uqinisekise uhlobo lwebhondi, uyilo lwecandelo, ubungakanani besarha, ubunzulu bokusika kunye nokusetyenziswa okumanzi okanye okomileyo.
| Izinto eziphathekayo | I-Blade ecetyiswayo | Uhlobo lweBond | Eyona ndlela ilungileyo yokusika |

Sebenzisa le tshathi njengesihluzo sokuqala. Ukuba ufuna uthelekiso olunzulu phakathi kwezinto ezisetyenziswa kwindlela, funda esi sikhokelo ku ukukhetha ibhleyidi yesarha yekhonkrithi vs i-asphalt Ukhetho lokugqibela lweblade luxhomekeke kububanzi beblade, ubungakanani be-arbor, amandla esarha, ubunzulu bokusika, umlinganiselo we-RPM kunye nokuba amanzi akhona na.
Ikhonkrithi ecociweyo iqinile, ingakumbi xa ine-aggregate exineneyo. Iyayithuntubeza idayimani eziveziweyo, ngoko ke i-bond kufuneka iguge ngokwaneleyo ukuze iveze iidayimani ezintsha zokusika. Izikhokelo zeedayimani zihlala ziphatha ikhonkrithi kwi- 3,000 psi okanye ngaphantsi njengezinto ezithambileyo kunye nekhonkrithi kwi- 6,000 psi okanye ngaphezulu njengezinto eziqinileyo. Oko kunika iinjineli kunye nabathengi indawo eluncedo yokuqala ngaphambi kokujonga uhlobo lwe-aggregate kunye nokuqinisa.
I-Asphalt ithambile kunekhonkrithi ecociweyo, kodwa irhabaxa ngakumbi. Isanti kunye ne-aggregate kwi-asphalt zinokutya umongo we-blade ukuba kusetyenziswe i-blade engalunganga. Yiyo loo nto i-blade yedayimani ye-asphalt idla ngokusebenzisa i-hard bond kunye nokukhusela okungaphantsi. Ngolwimi oluqhelekileyo, i-asphalt ayisiyo "khonkrithi elula." Yi-blade grinder enxibe i-road costume.
Iislabhu eziqinisiweyo zongeza enye ingxaki: intsimbi. Iblade yedayimani yesamente ene-rebar ifuna iindawo eziqinileyo, uxinzelelo lokutya oluzinzileyo kunye nokupholisa kakuhle. Ukusikwa okumanzi kudla ngokuba lolona khetho lukrelekrele kuba ukudibana kwentsimbi kudala ubushushu ngokukhawuleza.
| Uhlobo lweBond | Eyona ilungileyo | Ukuba isetyenziswe ngendlela engafanelekanga |
|---|---|---|
| Ibhondi ethambileyo | Ikhonkrithi eqinileyo, i-aggregate eqinileyo, ikhonkrithi eqinisiweyo | Inxiba ngokukhawuleza kakhulu kwi-asphalt |
| Ibhondi ephakathi | Umsebenzi oqhelekileyo wekhonkrithi kunye nomsebenzi oxutyiweyo | Iyamkeleka, kodwa ayisoloko ifanelekile |
| Ibhondi eqinileyo | I-Asphalt, ikhonkrithi eluhlaza, ibhloko erhabaxa | Ingagqunywa kwikhonkrithi eqinileyo |
I-Aggregate nayo ibalulekile. Ezinye izikhokelo zokukhetha iiblade zihlela i-aggregate enkulu kune -3/4 intshi njenge-aggregate enkulu, ngelixa i-aggregate engaphantsi kwe -3/8 intshi kulula ukuyisika kodwa isenokuguga ngokukhawuleza. Yiyo loo nto ii-slabs ezimbini ezinamandla afanayo okucinezelwa zisenokusika ngokwahlukileyo. Ikhonkrithi inoburharha, kwaye idla ngokuyifihla ngaphakathi kwi-aggregate.
Kwikhonkrithi ecociweyo, qala nge-blade yedayimani yekhonkrithi ehlukanisiweyo. Ukuba ikhonkrithi iqinile okanye i-blade iqala ukugquma, yiya kwi-bond ethambileyo. Ukuba ikhonkrithi ithambile kwaye irhabaxa, yiya kwi-bond eqinileyo. Ukuze ufumane ezinye iindlela zezixhobo ezinxulumene noko, ungajonga kwakhona imela yesarha yekhonkrithi iphepha.
Ukukhethwa kweblade yesarha yesarha yesarha kufanele kuhambelane nesarha. Umzekelo, Iinkcukacha zeHusqvarna K 770 dwelisa iblade eyi-intshi ezili-14 , ubunzulu bokusika obuyi-intshi ezi-5 , imveliso ye-hp ezi-5 kunye nesantya esiphezulu se-peripheral se-18,000 fpm . Ezo manani zisisikhumbuzo sokuba ukukhetha iblade akupheleli nje kwizinto eziphathekayo. Ububanzi, ubungakanani be-arbor kunye nomlinganiselo wesantya kufuneka zihambelane nomatshini.
Xa usikwa i-asphalt, sebenzisa i-asphalt diamond blade eyenzelwe yona. Ifanele ibe ne-bond eqinileyo, i-slurry clearance elungileyo kunye nokhuseleko olungaphantsi. UNorton uqaphela ukuba i-undercut ingakhokelela ekulahlekelweni kwecandelo, kwaye ucebisa ukhuseleko olungaphantsi okanye ukuhamba kwamanzi okwandileyo apho izinto ezirhabaxa zihlasela intsimbi.
Iblade eqhelekileyo ye-asphalt ibonisa indlela ezi zixhobo ezinokuba zezona zikhethekileyo ngayo. I-CMT idwelisa i-asphalt blade engama-300 mm ene- 8 mm enganqunyulwanga kakuhle , i-20 mm bore kunye ne-6,400 rpm ephezulu , kwaye iyiphawula njengengafanelekanga kwikhonkrithi okanye ikhonkrithi eqinisiweyo. Kwimisebenzi yokuhamba ngeenyawo nge-asphalt, dibanisa i-blade nomsiki ofanelekileyo, njenge- umsiki wekhonkrithi yepetroli wokusika i-asphalt kunye nekhonkrithi .
Kwikhonkrithi eqinisiweyo, sebenzisa i-blade elinganiswe ukuba iqhagamshelane ne-rebar. I-bond ethambileyo ukuya kwephakathi inceda i-blade ukuba iqhubeke nokusika ikhonkrithi eqinileyo, ngelixa ulwakhiwo oluqinileyo oluneziqendu lunceda ukuba ihlale ishushu kwaye ichaphazeleka xa kuvela intsimbi. Iziqendu ezifakwe nge-laser zihlala zikhethwa xa kusikwa nzima kuba uqhagamshelo lweziqendu luqina phantsi kweemeko ezinzima.
Musa ukuyinyanzela iblade xa ifika kwi-rebar. Gcina ukutya kuzinzile, sebenzisa amanzi xa kunokwenzeka kwaye uphephe ukujika isarha kwindawo enqunyulweyo. Ukuba iblade iqala ukutsha, isarha iqala ukutsiba, okanye umqhubi uqala ukuthetha nomatshini, yima uze uhlole indlela ebekwe ngayo.
Ukusikwa okumanzi akupheleli nje ekusetyenzisweni kweencakuba. Isikhokelo se-silica sokwakha i-OSHA imisela inqanaba lesenzo se-silica esikrwada esiphefumulayo kwi- 25 μg/m³ kunye nomda wokuvezwa ovumelekileyo kwi- 50 μg/m³ , zombini njenge-avareji yexesha elinobunzima beeyure ezisi-8. Oko kwenza ukusika okumanzi kube sisigqibo sokulawula uthuli kunye nesigqibo sokupholisa.
Ukusika okomileyo kuluncedo kwiindlela ezimfutshane kunye nomsebenzi wokulungisa, kodwa kuphela ngeblade elinganiswe ukuba isetyenziswe yomile. Ungaze usebenzise iblade emanzi kuphela. Oko akusiyo indlela ekhawulezayo yokutshisa, ukugquma kunye neblade ebiza kakhulu ngequbuliso. Ukuze ufumane uthelekiso olunzulu, funda ukusika ikhonkrithi emanzi vs eyomileyo .
I-blade elungileyo kwisarha engalunganga isanika iziphumo ezimbi. Ngaphambi kokuba usike, qinisekisa ububanzi be-blade, ubungakanani be-arbor, i-RPM ephezulu, ubunzulu bokusika, amanzi kunye namandla esarha. Ukuba umsebenzi ubandakanya ukunqunyulwa kwendlela ende, ukulungiswa kwendlela okanye ukugawulwa kwemisele, esi sikhokelo sikwi indlela yokukhetha isarha yendlela efanelekileyo yokusika ikhonkrithi kunye ne-asphalt linyathelo elilandelayo elingcono.
Kwabo bathengisa oomatshini, isikhokelo sokugqibela soomatshini bokusika ikonkrithi kunye noomatshini bokusika indlela inika umxholo ongakumbi ngohlobo lomatshini, ubunzulu bokusika kunye nomsebenzi wendlela. Ukuba ufuna umbono obanzi wokusetyenziswa, inqaku elimalunga iingenelo zesarha yendlela zokulungisa ikhonkrithi, i-asphalt kunye neendlela zokuhamba ngeenyawo ikwayindlela eluncedo yokujonga izinto zangaphakathi.
Impazamo yokuqala kukusebenzisa iblade enye kwikhonkrithi, i-asphalt kunye nee-slabs eziqinisiweyo. Eyesibini kukungayinaki i-bond hardness. Eyesithathu kukugxeka isarha xa ingxaki yokwenyani ikukugquma kweblade, i-RPM engalunganga, ukupholisa kakubi okanye ukufana kwezinto ezingalunganga.
Ukuba incakuba yedayimani ayivumi ukusika, jonga ikhonkco, izinto ezisetyenzisiweyo, isantya sesarha kunye nokunikezelwa kwamanzi ngaphambi kokuba uyityhale ngamandla. Incakuba elungileyo kufuneka isike ngoxinzelelo oluqhubekayo. Ukuba kufuneka ulwe nesarha, incakuba mhlawumbi ikuxelela into ethile. Ngaloo mpazamo ithile, sebenzisa esi sikhokelo kwi ukugcada kweblade yedayimani kunye nesizathu sokuba iblade iyeke ukusika .
Sebenzisa itshathi yokukhetha ibhleyidi yedayimani ukunciphisa ukhetho, uze uqinisekise izinto ezine: izinto zokwakha, ibhondi, isarha yokulinganisa kunye nendlela yokusika. Kwisamente, cinga ngamandla kunye ne-aggregate. Kwi-asphalt, cinga ngokukrazula kunye nokukhusela ukunqunyulwa. Kwi-slabs eziqinisiweyo, cinga ngentsimbi, ubushushu kunye nokupholisa.
Incakuba yasekunene ayikhawulezi nje kuphela. Isebenza ipholile, ihlala ixesha elide, inciphisa ixesha lokungasebenzi kwaye yenza umqhubi abonakale ngathi ucwangcise yonke into kwasekuqaleni.
