Roller chains yog ib qho tseem ceeb hauv ntau yam kev lag luam thiab kev siv tshuab, suav nrog tsheb, kev tsim khoom thiab kev ua liaj ua teb. Lawv yog siv los xa hluav taws xob zoo thiab thauj khoom. Txawm li cas los xij, cov khoom siv hauv cov hlua khi tuaj yeem muaj kev cuam tshuam loj rau ib puag ncig. Kev nkag siab txog kev cuam tshuam ib puag ncig ntawm cov khoom siv rau cov hlua khi yog qhov tseem ceeb rau kev txiav txim siab paub txog lawv kev siv thiab pov tseg.
Cov khoom siv feem ntau siv rau cov menyuam chains yog steel, stainless hlau, thiab carbon steel. Los ntawm kev rho tawm cov khoom siv raw mus rau cov txheej txheem tsim khoom thiab pov tseg zaum kawg, txhua yam khoom muaj nws tus kheej ib puag ncig.
Hlau yog cov khoom siv dav tshaj plaws hauv cov hlua khi thiab feem ntau yog tsim los ntawm cov hlau ore thiab thee. Kev rho tawm ntawm cov khoom siv raw no suav nrog kev siv hluav taws xob tseem ceeb thiab kev cuam tshuam ib puag ncig. Cov txheej txheem ntawm smelting hlau ore los tsim hlau kuj tso tawm carbon dioxide thiab lwm yam tsev cog khoom gases rau hauv cov huab cua, ua rau muaj kev hloov pauv huab cua. Tsis tas li ntawd, kev tsim steel muaj kev siv ntau yam tshuaj thiab tsim cov khoom pov tseg uas tuaj yeem paug dej thiab av.
Stainless hlau yog ib qho corrosion-resistant alloy hlau uas muaj chromium, npib tsib xee thiab lwm yam khoom. Thaum cov hlau tsis muaj steel muaj kev ruaj khov thiab siv tau ntev, kev rho tawm thiab ua tiav ntawm nws cov ntaub ntawv raw, tshwj xeeb yog chromium thiab npib tsib xee, tuaj yeem muaj kev cuam tshuam ib puag ncig. Kev khawb thiab ua kom zoo ntawm cov hlau no tuaj yeem ua rau muaj kev puas tsuaj hauv vaj tse, av yaig thiab dej paug. Tsis tas li ntawd, kev tsim cov hlau tsis muaj steel yuav tsum muaj lub zog tseem ceeb, ua rau cov pa roj carbon emissions thiab cov peev txheej depletion.
Cov pa roj carbon steel yog lwm cov khoom siv uas muaj nyob rau hauv cov hlua khi thiab feem ntau yog tsim los ntawm hlau thiab carbon. Kev tsim cov pa roj carbon steel muaj kev txhawj xeeb ib puag ncig zoo ib yam li cov hlau ib txwm muaj, suav nrog kev tsim cov hlau ore thiab thee, thiab tso tawm cov pa roj hauv tsev cog khoom thaum lub sijhawm tsim khoom. Tsis tas li ntawd, cov ntsiab lus ntawm cov pa roj carbon monoxide ua rau nws muaj kev cuam tshuam rau corrosion, uas tuaj yeem ua rau hnav thiab hloov ntxov ntxov, cuam tshuam rau ib puag ncig.
Nyob rau hauv xyoo tas los no, tau muaj kev txaus siab los tshawb nrhiav lwm cov khoom siv rau cov hlua khi uas tuaj yeem txhim kho ib puag ncig kev ua haujlwm. Ib qho khoom siv zoo li no yog yas, uas muaj peev xwm txo tau qhov kev cuam tshuam ib puag ncig ntawm cov menyuam chains. Cov hlua yas tuaj yeem tsim los ntawm cov khoom siv rov ua dua tshiab, txo qhov kev xav tau ntawm cov peev txheej nkauj xwb thiab tshem tawm cov khib nyiab los ntawm qhov chaw pov tseg. Tsis tas li ntawd, cov chains yas yog lub teeb yuag, corrosion-resistant, thiab yuav tsum tau siv zog tsawg dua los tsim cov hlau chains.
Lwm qhov kev cog lus yog kev siv cov khoom siv bio-based, xws li bioplastics, hauv kev tsim cov hlua khi. Bioplastics yog muab los ntawm cov khoom siv txuas ntxiv dua tshiab xws li pob kws, qab zib los yog cellulose thiab yog lwm txoj hauv kev zoo dua rau cov khoom siv yas. Kev tsim cov bioplastics feem ntau muaj qis dua cov pa roj carbon monoxide thiab muaj kev cuam tshuam me me rau ib puag ncig dua li cov khoom siv roj av.
Tsis tas li ntawd, kev nce qib hauv cov khoom sib xyaw xws li carbon fiber reinforced polymers muab lub peev xwm los txhim kho ib puag ncig kev ua haujlwm ntawm cov menyuam chains. Cov ntaub ntawv no yog lub teeb yuag, ruaj khov thiab muaj lub zog-rau-hnyav piv, txo lub zog noj thaum lub sijhawm ua haujlwm thiab txo qis qhov xav tau kev hloov ntau zaus.
Ntxiv nrog rau kev tshawb nrhiav lwm cov ntaub ntawv, kev tsim thiab kev saib xyuas ntawm cov hlua khi kuj tseem cuam tshuam rau kev cuam tshuam ib puag ncig. Kev lubrication thiab kev saib xyuas kom zoo tuaj yeem txuas ntxiv kev pab cuam lub neej ntawm cov menyuam chains, txo qhov hloov zaus thiab cuam tshuam ib puag ncig hneev taw. Tsis tas li ntawd, kev tsim cov saw hlau zoo dua thiab ruaj khov tuaj yeem pab txuag cov peev txheej thiab txo cov khoom pov tseg.
Thaum cov saw hlau txuas mus txog qhov kawg ntawm nws lub neej muaj txiaj ntsig, kev pov tseg kom raug thiab rov ua dua tshiab yog qhov tseem ceeb los txo nws qhov cuam tshuam rau ib puag ncig. Recycling hlau chains pab txuag cov peev txheej ntuj thiab txo lub zog xav tau los ua cov saw tshiab. Tsis tas li ntawd, kev rov ua dua tshiab ntawm cov yas thiab bio-based chains tuaj yeem ua rau muaj kev lag luam ncig, tso cai rau cov ntaub ntawv rov qab siv dua thiab rov ua dua, yog li txo qhov hnyav ntawm ib puag ncig.
Hauv cov ntsiab lus, cov ntaub ntawv siv rau hauv cov menyuam cov hlua muaj qhov cuam tshuam loj rau ib puag ncig los ntawm kev rho tawm thiab kev tsim khoom mus rau qhov kawg pov tseg. Thaum cov ntaub ntawv ib txwm muaj xws li steel thiab stainless hlau tau ntev lawm cov ntaub ntawv ntawm kev xaiv rau cov menyuam saw ntau lawm, muaj kev loj hlob xav tau los tshawb nrhiav lwm cov ntaub ntawv uas tuaj yeem txhim kho ib puag ncig kev ua tau zoo. Los ntawm kev txiav txim siab txog kev cuam tshuam ib puag ncig ntawm cov khoom siv rau cov menyuam thiab siv lwm txoj hauv kev ruaj ntseg, kev lag luam tuaj yeem txo lawv cov hneev taw ecological thiab pab txhawb rau yav tom ntej ntsuab.
