Ukukhethwa Kwe-Concrete Saw Blade Ye-Concrete vs Asphalt
Ukukhetha i-saw blade yekhonkrithi esebenzayo kuqala ngezinto zokwakha, hhayi ububanzi be-blade. Ikhonkrithi ne-asphalt kungasikwa kokubili ngama-blade edayimane, kodwa kugqoka i-bond yensimbi ngezindlela ezahlukene. Ikhonkrithi eqinile ivame ukuthuntubeza amadayimane avele ngaphambi kokuba i-bond ezungezile iguge, kuyilapho i-asphalt ekhuhlayo ingasusa i-bond ngokushesha futhi ihlasele ngisho nengaphakathi lensimbi elingaphansi kwezingxenye.
Lokhu kudala umthetho wokukhetha ozwakala uhlehla kancane: izinto eziqinile, ezingagugi kakhulu ngokuvamile zidinga isibopho esithambile, kuyilapho izinto ezithambile kodwa ezigugi kakhulu ngokuvamile zidinga isibopho esiqinile. Isibopho esithambile sikhipha amadayimane agugile futhi siveze izindawo ezintsha zokusika. Isibopho esiqinile sinciphisa ukuguguleka lapho kusikwa i-asphalt noma ukhonkolo oluhlaza. UNorton uchaza lokhu njengobudlelwano "obudonsela okuphambene" phakathi kwesibopho se-blade nezinto ezisikiwe.
I-Concrete Blade vs I-Asphalt Blade: Ukuqhathanisa Okusheshayo
| Isici sokukhetha | I-blade yekhonkrithi | I-Asphalt blade |
|---|---|---|
| Izinto ezijwayelekile | Ukhonkolo oqinisiwe noma oqinisiwe | I-asphalt, ukhonkolo oluhlaza kanye nokwakhiwa ngokhuni okukhuhlayo |
| Isiqondiso sesibopho esivamile | Isibopho esithambile se-aggregate eqinile, ephansi yokuguguleka | Isibopho esinzima sezinto ezikhahla kakhulu |
| Umklamo wesigaba esivamile | Kufaniswe nokuhlanganiswa kanye nokuqinisa | Ama-gullet abanzi kanye nokuvikelwa okunqunyiwe |
| Inkinga evamile yokukhetha | Isibopho esiqine kakhulu singase siqine | Isibopho esithambile kakhulu singase siguge ngokushesha |
| Umbuzo oyinhloko wokuthenga | Iqine kangakanani i-aggregate, futhi ingabe i-rebar ikhona? | Ingakanani indlela egandayiwe, futhi ubude bayo bude kangakanani? |
Kungani Ikhonkrithi Ne-Asphalt Zidinga Ama-Blade Bond Ahlukene
I-blade yedayimane inquma ukuguguleka okulawulwayo. Amadayimane avele avele ayagaya indwangu, kuyilapho isibopho sensimbi esiwazungezile siwohloka kancane kancane. Njengoba amadayimane amadala eba buthuntu noma ephuka, amadayimane amasha kufanele avele ngesivinini esifanayo. Uma inqubo ihlala ilinganisiwe, i-blade iyaqhubeka nokusika ngaphandle kokulahlekelwa ukuphakama kwengxenye ngokushesha okukhulu.
Uma isibopho sinzima kakhulu kunendwangu, singase singagugi ngokushesha ngokwanele ukuze siveze amadayimane amasha. Ubuso besigaba buba bushelelezi, isivinini sokusika siyehla futhi i-blade iqala ukucwebezela. Uma isibopho sithambile kakhulu, i-matrix yensimbi iyanyamalala ngaphambi kokuba amadayimane asetshenziswe ngokugcwele. I-saha ingase isaqhubekela phambili, kodwa isabelomali se-blade sizohamba ngakolunye uhlangothi.
I-asphalt idala enye inkinga eyaziwa ngokuthi undercutting. Izinhlayiya ezi-abrasive zingaguga i-core yensimbi ngqo ngaphansi kwezingxenye zedayimane, zenze buthaka ukuxhumana phakathi kwengxenye nomzimba we-blade. I-Norton itusa izivikeli ezi-undercut noma imiklamo efanayo yezingxenye zezinto ezi-abrasive, kuyilapho i-Hilti isebenzisa izingxenye ezizinikezele ezi-undercut blade yayo ye-SPX asphalt. Yingakho i -asphalt saw blade kufanele ihlolwe ngaphansi kwengxenye kanye nakulo lonke ungqimba lwedayimane olubonakalayo.
Thola Izinto Ngaphambi Kokukhetha I-Blade
Ukhonkolo Olungisiwe Noqinisiwe
Ikhonkrithi eqinisiwe akufanele iphathwe njengento eyodwa efanayo. I-aggregate ivame ukuba nethonya elikhulu ekuziphatheni kwe-blade kunamandla ekhonkrithi anyatheliswe kuthekithi lokulethwa. I-aggregate eqinile ingandisa ingozi yokugqwala lapho ibhondi iguga kancane kakhulu, kuyilapho i-aggregate ethambile noma ekhafula kakhulu inganciphisa impilo yengxenye.
Ikhonkrithi eqinisiwe yengeza insimbi endleleni yokusika. Ngakho-ke i-blade kumele ilinganiswe kokubili ikhonkrithi kanye ne-rebar, futhi isaha kumele linikeze amandla anele ukugcina isivinini sokusika esizinzile. I-blade esika kancane ayigugi njalo. I-Norton ibala i-bond eqinile kakhulu, izinto eziqinile kanye namandla omshini anganele phakathi kwezimbangela ezivamile zokugqwala. Uma i-blade idinga ukubopha ngokuphindaphindiwe, ukushintshela ku-bond ethambile ngokuvamile kunengqondo kakhulu kunokuncika kakhulu esibambweni.
Ukhonkolo Oluhlaza
Ikhonkrithi eluhlaza idinga i-blade ehlukile kanye nendlela yokusika. I-Husqvarna ithi uhlelo lwayo lwe-Soff-Cut Ultra Early Entry lungaqala ukusika amajoyinti okufinyela cishe ihora elilodwa kuya kwamabili ngemva kokukhipha i-trowelling nangaphambi kokusetha kokugcina . Ifasitela eliqondile lisaxhomeke ekuxubeni, izinga lokushisa le-slab kanye nezimo zokuqeda, kodwa ububanzi obushicilelwe buchaza ukuthi kungani ama-blade okuqala ehluka kuma-blade avamile aqinile.
Kulesi sigaba, i-samente paste isakhula ngamandla, kuyilapho isihlabathi esixegayo kanye ne-aggregate kungahlala kukhuhla kakhulu. I-blade kumele yakhe i-joint ngaphandle kokudabula imiphetho noma ukubangela ukuqhekeka kobuso. I-concrete eluhlaza ingase ibe yintsha, kodwa isivele ifundile ukwenza ukukhetha i-blade kube nzima.
I-Asphalt Ngaphezu Kokhonkolo
Ukulungiswa kwemigwaqo ngezinye izikhathi kudinga ukusika okukodwa ukuze kudlule phezu kwe-asphalt bese kuqhubeka kube yisisekelo sekhonkrithi. I-asphalt blade ezinikele ingase yehlise ijubane ngemva kokufinyelela kukhonkrithi eqinile, kuyilapho i-concrete blade ingalahlekelwa izinto ezibophayo ngokushesha kungqimba lwe-asphalt. Ezindaweni ezixubile ngezikhathi ezithile, i-asphalt-over-concrete blade evunyelwe noma esetshenziswa kabanzi inganciphisa isidingo sokushintsha i-blade.
Ukuze uthole umsebenzi wokukhiqiza omude, qhathanisa intengo ye-blade, amamitha okusika aqediwe kanye nesikhathi sokushintsha i-blade ye-blade eyodwa yezinto ezixubile ngokumelene ne-blade ezimbili ezizinikele. Ngaphandle kwalezo zibalo, ukubiza inketho eyodwa ngokuthi “ishibhile” ikakhulukazi kuwukuthi ube nethemba lokugqoka isigqoko esiqinile.
Qondanisa i-Diamond Blade ne-Concrete Saw
Uma izinto zokwakha kanye nesibopho sekukhethiwe, i-blade kumele ifaniswe nomshini. Hlola ububanzi be-blade, usayizi we-arbor, ukuhlelwa kwe-drive-pin, i-RPM ephezulu, amandla esaha kanye nokuvunyelwa okumanzi noma okomile njengohlelo olulodwa. I-blade ingase ilingane phezu kwe-arbor kodwa iqhubeke ingalungile ngesivinini somshafti, isivikelo noma amandla atholakalayo.
Ubudlelwano phakathi kobubanzi kanye ne-RPM bucacile ebangeni le-MK Diamond's MK-3000. Ukucushwa kwayo okungamasentimitha angu-20 kusebenza ku-2,580 rpm futhi kufinyelela ekujuleni kokusika okushicilelwe okungaba ngu-191 mm. Inguqulo engamasentimitha angu-26 isebenza ku-2,030 rpm futhi ifinyelela cishe ku-267 mm, kuyilapho inguqulo engamasentimitha angu-30 isebenza ku-1,680 rpm futhi incipha cishe ku-318 mm.
| Ukucushwa kwe-MK-3000 | Ububanzi be-blade | Isivinini se-blade esishicilelwe | Ukujula kokusika okushicilelwe |
|---|---|---|---|
| I-MK-3020 | 20 inches / 508 mm | 2,580 ngomzuzu | 191 mm |
| I-MK-3026 | 26 in / 660 mm | 2,030 ngomzuzu | 267 mm |
| I-MK-3030 | 30 inches / 762 mm | 1,680 ngomzuzu | 318 mm |
Lezi zibalo zisebenza ebangeni elilodwa lesaha, kodwa isifundo sobunjiniyela sibanzi: njengoba ububanzi be-blade bukhula, isivinini esifanele somgodi sivame ukushintsha. I-blade enkulu kakhulu ayikwazi ukufakwa ngokuphepha ngokuhlola imbobo ye-arbor kuphela.
Usayizi Wesitshetshe Sokusaha Sikakhonkolo Nokujula Kokusika
Irediyasi ye-blade ayifani nokujula kokusika okusebenzisekayo. I-arbor, i-flange, i-guard kanye ne-chassis kuthatha ingxenye yerediyasi, kuyilapho ukuguguleka okuvamile kwesigaba kunciphisa kakhulu. I-MK Diamond ibala ukujula kokusika okubhekiselwe cishe ku-102 mm kwe-blade engamasentimitha angu-12, u-127 mm kwe-blade engamasentimitha angu-14, u-178 mm kwe-blade engamasentimitha angu-18 kanye no-203 mm kwe-blade engamasentimitha angu-20.
| Ububanzi be-blade | Ukujula kokusika okubhekiselwe |
|---|---|
| 12 in / 305 mm | Cishe u-102 mm |
| 14 in / 356 mm | Cishe u-127 mm |
| 18 in / 457 mm | Cishe u-178 mm |
| 20 inches / 508 mm | Cishe ama-203 mm |
| 24 in / 610 mm | Cishe ama-254 mm |
Ukusikwa okudingekayo okungu-100 mm kushiya cishe u-2 mm wesilinganiso somqondo ngokumelene nenani eliyinkomba elingu-102 mm le-blade engamasentimitha angu-12. Leyo silinganiso asivumeli ukuguguleka kwe-blade, usayizi we-flange, i-guard clearance noma i-slab engalingani. Ngakho-ke ukukhetha kokugcina kumele kulandele ububanzi be-blade obuvunyelwe ngumenzi we-saw kanye nokujula kokusika okulinganiselwe.
Idatha yomshini we-ACE inikeza isibonelo esiwusizo. I-QF400 concrete road saw yamukela i-blade engu-400 mm futhi inobubanzi obukhulu bokusika obushicilelwe obungu-130 mm. Umsiki wekhonkrithi ne-asphalt we-QF500 isebenzisa i-blade engu-500 mm futhi ifinyelela ku-180 mm. Lezi zilinganiso zomshini ziwusizo kakhulu ekuthengeni kunokulinganisa ukujula kusuka kububanzi be-blade kuphela.
I-Wet vs Dry Concrete Cutting Blade
Ukusika okumanzi kusiza ukupholisa i-blade nokuthutha udoti wokusika, kodwa futhi kuyindlela yokulawula ukuchayeka. Ngaphansi kwezindinganiso ze-silika zokwakha ze-US OSHA, izinga lesenzo se-silica ekristalu ephefumulayo lingu- 25 μg/m³ , kuyilapho umkhawulo wokuchayeka ovunyelwe ungu- 50 μg/m³ . Zombili lezi zibalo zilinganiswa njengezilinganiso zesikhathi samahora ayisishiyagalombili.
Ithebula le-OSHA 1 lidinga ukuthi amasaha ahamba ngemuva asebenzise uhlelo oluhlanganisiwe lokulethwa kwamanzi oluqhubeka nokunikeza amanzi ensikeni. Umsebenzi wangaphandle owenziwa ngaphansi kwale ndlela awubhalisi isidingo esengeziwe sokuphefumula, kuyilapho umsebenzi wangaphakathi noma ovalekile udinga okungenani ukuvikelwa kokuphefumula kwe-APF 10. Le mithetho isebenza emsebenzini wokwakha wase-US ohlanganisiwe; osonkontileka kwezinye izimakethe kufanele balandele imithetho yendawo.
| Into ye-OSHA | Imfuneko eshicilelwe |
|---|---|
| Izinga lesenzo se-silica | 25 μg/m³ ngaphezu kwe-TWA yamahora angu-8 |
| Umkhawulo wokuvezwa ovunyelwe | 50 μg/m³ ngaphezu kwe-TWA yamahora angu-8 |
| Ukulawula isaha lokuhamba ngemuva | Ukulethwa kwamanzi okuhlanganisiwe okuqhubekayo ebaleni |
| Umsebenzi wangaphandle | Akukho siphefumuli esengeziwe esibhalwe ngaphansi kweThebula 1 |
| Umsebenzi wangaphakathi noma ovalekile | I-APF encane kakhulu engu-10 |
Ukusika okomile kuhlala kuwusizo lapho ukungcola kungenakulawuleka noma amanzi engatholakali, kodwa kokubili i-blade kanye ne-saw kumele kuvunyelwe ukusebenza okomile. Ukujula kokudlula, isikhathi sokusika esiqhubekayo kanye nezikhawu zokupholisa kufanele kulandele imiyalelo yemishini ekhethiwe kunomthetho wesikhathi ojwayelekile. Ilebula elimanzi kuphela liwumkhawulo wokusebenza, hhayi isiphakamiso sokuhlonipha.
Amaphutha Okukhetha I-Common Concrete Saw Blade
Amaphutha avamile afaka phakathi ukukhetha ububanzi kuphela, ukusebenzisa i-blade yekhonkrithi ngokuphindaphindiwe ku-asphalt, ukunganaki i-aggregate, ukweqa isilinganiso se-RPM somshini kanye nokucabanga ukuthi yonke i-blade yekhonkrithi ingasika ukuqina okunzima. Elinye iphutha elivamile ukukhetha i-blade enkulu ukuze kujule kakhulu ngaphandle kokuhlola ukuthi ingabe i-saw inamandla anele okugcina isivinini sokusika esifanele.
Qaphela i-blade ngesikhathi sesigaba sokuqala sokusika. Ubuso besigaba obubushelelezi, uthuli oluncane kanye nesivinini sokusika esiwayo kungabonisa ukucwebezela. Ukulahleka kwesigaba okusheshayo kusikisela ukuthi isibopho siyaphela ngokushesha kakhulu. Ukunqunywa ngaphansi kwezingxenye kukhomba ezintweni ezihuzukayo, amanzi anele noma i-blade engenasivikelo esifanele se-core. Lezi zimpawu ziwusizo kakhulu kunokulinda i-blade ukuthi ifake isikhalazo esisemthethweni.
Uhlu Lokuhlola Lokukhetha I-Concrete Saw Blade
Ngaphambi koku-oda, qinisekisa izinto eziqondile, ubudala bekhonkrithi, isimo sokuhlanganiswa, ukuqinisa, ukujula kokusika okudingekayo, imodeli yesaha, ububanzi be-blade, usayizi we-arbor, i-RPM ephezulu kanye nendlela yokusika evunyelwe. Bese uqhathanisa izindleko ze-blade ngemitha eqediwe kunentengo yokuthenga yodwa.
Khetha i-blade yokusika ukhonkolo eyenzelwe umsebenzi ojwayelekile wekhonkolo oqinisiwe noma oqinisiwe. Sebenzisa i-blade ye-asphalt enesibopho esifanele kanye nesivikelo esinqunyiwe sokunciphisa umgwaqo ohambayo. Khetha i-blade yezinto ezixubile ezivunyelwe lapho ukusika kuwela i-asphalt nokhonkolo ngokuphindaphindiwe. Isigaba se-blade sakha uhlu olufushane; izinto kanye nezincazelo zomshini zenza isinqumo sokugcina.
imibuzo ejwayelekile ukubuzwa
Ingabe i-blade yekhonkrithi ingasika i-asphalt?
Kungase kusike i-asphalt, kodwa isibopho esikhethiwe sekhonkrithi eqinile singaguga ngokushesha endleleni egandayiwe. Sebenzisa i-asphalt blade ekhethekile noma i-blend evunyiwe yezinto ezixubile emsebenzini womgwaqo ojwayelekile.
Ingabe i-asphalt blade ingasika ukhonkolo?
Ingase isike ukhonkolo othambile, kodwa ukubopha kwayo okuqinile kungagqwala kube yinhlanganisela eqinile ngoba amadayimane agugile awavezwa ngokushesha ngokwanele.
Yiliphi i-blade elidingekayo ukuze kwenziwe ukhonkolo oqinisiwe?
Sebenzisa i-blade elinganiswe ngokucacile kukhonkolo eqinisiwe bese uyifanisa ne-aggregate, ukuxhumana kwensimbi okulindelekile, amandla esaha, ububanzi kanye ne-RPM ephezulu.
Yimuphi usayizi we-blade odingekayo ukuze kunqunywe u-100 mm?
I-blade engamasentimitha angu-12 inobubanzi bokusika obuyireferensi obungaba ngu-102 mm, okushiya u-2 mm kuphela wesilinganiso somqondo. Sebenzisa ububanzi bokusika obulinganiswe ngesaha kanye nobubanzi be-blade obuvunyelwe ukwenza ukukhetha kokugcina.
Ingabe i-blade yedayimane emanzi ingasetshenziswa yomile?
Kuphela uma umenzi we-blade eyimaka kokubili ukusetshenziswa okumanzi nokomile. I-blade emanzi kuphela incike emanzini ukuze ipholise futhi isuse udoti.
