Amatempurhara Angaphezulu: Ubuchwepheshe Bezulu, Ukuphazamisa, NeSabelo Esingaphambilini

Ubunzima Bekhosi Lokuqina Ngokuzula NeMoto Yokuhlukunyezwa Yezigaba ZeDiamond

Xa izinkeleni ziyekwa kuzo ngaphezulu kwezi-40 degrees Celsius, i-steel cores phakathi kwezincamathelo ze-diamond ziqaqa kakhulu ngoba zinezikhashana ephakeme kakhulu zokuthutha. Oku kubangela ukuthutha okuphakade phakathi kwesimo sekore nasezincamathelweni ze-diamond ezothunywa kulo. Izidingo ziwuthathe ngokwengeziwa uma isimo sokudluliswa akuthuthi ngokulinganayo ne-steel core. Lokhu kungahluke kukhanya kakhulu futhi kubangela izinxenye zihlale njalo xa kususwa imisebenzi yokususa. Ngemva kwalokho isimo sikhanya kakhulu futhi kube yilokho ukuthi ikore yonke ihlanjululwe, ibangela incamathelo ithube ngendlela ayikholo ngayo kodwa ayisuse amazwi alandelayo. Sibona izibonelo eziningi emasitshalweni wasekuleshumi kumgca othile lapho izincamathelo zilahlekelwa ama-30% wezobuchwepheshe bazo ngokuthi kuphela kuyizinkinga zokushisa. Futhi, yini engiyifundisa? Lezinkinga zingaba kakhulu xa izinkeleni ziyekwa kuzo ngokugcwele.

Umbono Wokubona: Ukuphazamiseka Kwezindlela Zomqoka Ngemizuzwana 37% ephindwe kabili ku-42°C emakhaya Aphuma ePhoenix

Izivikelo zasekuleleni ezenzelwa ePhoenix zange zibonisa ukuthi izindlela ziqhubeka ngemizuzwana engu-37% ngapha kokuqhubeka kwazo ngenhloso yezimo eziphileneyo ezingu-25 izigaba. Umumbi wokuthi? Ukuhlupheka kwenziwa phakathi kuka ngemuva njengalokho izindlela iqhubeka iyahleha nokushisa nakunciphisa uma ikhishiza ikhombolo, okukhuphuka okudlulisayo okugcina konke kusuka ekugcineni kwanoma ziziphi izigaba zodiamond. Abasebenzi babona ukuthi kube nzima kakhulu ukulungiselela izinye izifanekiso ezikhuphuka ngaleso sikhathi seJulay esihluphekileyo—ngu-5 amaxesha ngaphezu kokuchaza—kunendlela ethile. Lezo zbono zasebhobheni zilindelela kangcono nezinto abamodeli engeza abazalise kudinga ngokushesha kwebhola. Okuthi sibona lapha kukuthi kanjani ishisa esiphambile singagcine izinkinga eziphansi ukuze kwenze izinkinga ezinkulu emuva.

Izimo Ezincane Zempililo: Ukuguqulwa Kwemfudlana, Ishisha Lempililo, Nenkohlaka Yekhishizo

Ukugcina Kwegolide YeseSteel Ngapha Ngesi 0°C Kunye Nokunyuswa Kwesishicelo Kusuka

Xa izinkalima zibuka ngezansi kwe-frozen, iingcinga ze-steel zizithola kwinto ebizwa ngokuba yi-ductile-to-brittle transition eyikwakho ukuba yahlulele ukukhulula kwazo ngaphandle kokuphindaphindiwe kabini okanye kangakanani njengo-40%. Le mikhumbi embandayo ethile esixhomeke khona siphazamiswa kakhulu xa ikhabha libe libusika ngoba umlilo uphinde uphinde kube luhlu, kuvela kulo minzobo yokugquma apho amaphutha aqala. Iimvavanyo ezidlulwa ziye zibanza le nto—amacaciso ayahlanjulwa kakhulu xa izixhobo zokugcina ziphatshelwa emathuba aphezulu kwezulu. Ngemva kwe-minus 15 degrees Celsius kunokungaphezulu komphathi obomnyama olandelayo oko-20 degrees, amacaciso ahlanjulwa phindaphinda kabini ngokulinganiselwa nedatha yendawo yesiseko. Kwiindlela eziphucwayo ekuhlabeni kwisifundwana seminyaka, lokhu kuthetha ukuba kumathuba afanelekanga angaphantsi. Abasebenzi bafunda ukuba kufuneka bacine ngokuncinane kwaye bakhangele izixhobo ngokuvikeleyo—ngobomi nothuso lwamazwi athile anqwalusele ukuba izixhobo zizakuvala.

Ukuphazanyiswa Kwesilingo Kwe-Thermal Kwezinkinga Kwezinkinga Ezinkulu Kusika Esibophephile

Xa kusebenza kusika esibophephile, amanzi okulahlahlala kwezinkinga zokugcina kuthinta kakhulu ngokuphazanyiswa kwezinkinga. Izinxenye ezikhuni zezilingo zihlukana ngokushesha xa zifinyelela amanzi okulahlahlala amaphakade amaphakade, okwakhiwa izikhungo kumongo. Iziraporo zokudala kubonisa ukuthi ngaphakathi kuka-78 kuka-100 kwezinkinga kusika esibophephile ngezansi kwe-5°C kuthinta ngaleso sikhungo. Ngokufanayo, amanzi okulahlahlala akhala ngokugunyaziwa kusika esibophephile, kuthinta kube ngama-30% angaphethelene ngokulahlela kakhulu. Lokhu kuthinta kakhulu kakhulu, okwakha izinkinga eziningi kumzimba wamadini. Ezinye izinkampani zizama ukusebenzisa amanzi okulahlahlala anqotedwa nge-glycol noma ukuguquka kwezinkinga zokugcina zomlilo ngokuvamile, kodwa lezi zindlela zihamba ngokusheshayo ngama-15-20% kusika sezintaba ngokubonakala kwezimali.

Imiphikiswano Yosika Kwezinkinga Zokuxhuma: Ukuxhuma Kwe-Resin Ngema-Metal Ngokungafani Kwezinsuku

Ukuxhunywa Kwe-Resin Kusika Esikhulu Kune-35°C Kwanjalo Ukuphazanyiswa Kwamadini

Xa izinkeleni ziyekwa ngaphezulu kusuku kwe-35 degrees Celsius, izinqamulo ze-resin ziqaqamisa futhi zilahle umthelelo wazo kuzinkinga ze-diamond grit. Imatriksi ye-polymer ihlukahluka futhi isebenzisela, okusho ukuthi izindilinga zihlala ngokushesha kakhulu kunalokho kufanelekile. Sikhuluma ngaproximately 40% ngokushesha kokuhlala kumasebe amakhaza kangcono kunalokho kumele kube khona lapho izinto ziqukethe ubude bendawo. Kutheni okulandelayo? Ukuncipha okungafanelekile nokwanda kwesimilo esivamile kusukela ekuhlukeni. Lokhu kudinga kakhulu kwenza into yonke ibe yinkinga entabaneni ngoba kuyashisa phansi lezo zinqamulo ngokwengeziwe. Uma umuntu ufuna izixhobo zakhe zibe namandla ngezinsuku zomhla ngaphandle kokubuyiselwa kuphela, izigameko zokugcina kumele zibe nzima futhi izindlela zokulibala kumele zibuyekezwe. Izinhlelo zokushisha zifuna ukwenza okubi noma kuphela ukwandisa isilinganiso se-coolant sizobenza isiphumo esikhulu ekugcinweni komlando wezixhobo ngezinsuku ezintabaneni.

Ukuqina Okuningi Kwe-Metal Bond Ngaphansi kuka -10°C Nokuphazanyiswa Kwesimo Se-Abrasive

Xa izinkaluba zibuka ngezansi kwe-10 degrees Celsius, izinqumulo zomgwa ziyaphakama kakhulu okungavumeli inkathi yokudonsa ngokuvamile futhi kugcine amakhristali akha e-diamond angafike. Oku kubukeka njengoba kwenziwa yiglazing, okusho ukuthi kudala umfanekiso ohlelekile owawusindiswa ngokudonsa. Izivikelo zibonisa ukuthi izilinganiso zokudonsa zingabuka kabusha 30 phesenti xa kusebenziswa kulezimo ezibusazisa. Ingenhla engunye ivela kulesi qiniso sokuthi isakhiwo esihlanzekile sikhathaza izixhumanisi ukuze zibe nomdla wakho wezinkinga nezigaba uma ziqeda into eyodwa. Ngaleso sikhathi, kufanele abasebenzisi bamncane kakhulu izilinganiso zabathaka bazo kwiinyanga zezulu futhi babuyekele ekutheni izinqumulo ezakhiwe ngokuthunyelwe kumaqondo afana nokukhula okwesibopho ukuze bakwazi ukubusa izinto ngemigaqo etholakalayo futhi bafumane ubude bezinsuku bezizinqumulo zabo.

Amehluko Wokusingatha Kwesibili: Ukuphazanyika Kwegunya kanye Nezinkinga Zokuguquguquka Kwesahluko

Ubude bezinsuku bethemperetsha bakhulisa indima ekhulu ngendlela amathuluzi ahlenzela kanjani kanye nezinhlayiya zihlinzeka kanjani phakathi kwemisebenzi yaphandle. Xa izigaba zethemperetsha ziye phezulu, izinhlelo ezithuthwa ngamanzi zilahlekelwa ubunzima ngokukhupha, okusabalalisa ukushumayela kwethemperetsha kabusha nge-30% emkhathini ongqongqo. Lokhu kungakwamiswa imiphumela engcono lapho iblade ziyashisa kangaka futhi ziqale ukuvuleka izindiamond eziguguzelela nge-700 degrees Celsius. Ekugcineni, izintambo ezahlukene zihlinzeka ngendlela eyahlukene ngenkathi izigaba zethemperetsha zishintsana. Ikonkreti njengoko ibecala igugu, ikhula ngama-15% angaphansi kwe-5 degrees Celsius. Kodwa isafalti ingcine inhliziyo enye, iyobala kakhulu xaxa izigaba zethemperetsha zifinyelela e-35 degrees noma phezulu. Lezi zinguquko zezinhlayiya zihlaziywa ngokudondolozeni indlela yokucutshuna kuzo. Izinhlayiya ezinobuchwepheshe zibangela ukuthi amathuluzi athintwayo acindeze kakhulu, ngelixa izihlangothi ezizinzile zibangela ukuthenjelwa kakhulu kumakhasimende ococweni. Kulabo bonke abasebenza emhlabeni, ukulandela lezi zimbono zethemperetsha kanye nokulungisa amanzi ococweni ngokulinganayo komkhathi kuyisidingo uma bafuna ukugcina imiphumo embulungwini yokucutshuna kanye nokunyusa ubude beqembu labo.
