Xa umntu ekhangela 'eyona wax ilungileyo yokuphosa iwax elahlekileyo', bahlala benethemba lempendulo elula, enobungakanani obunye. Leyo yimbono yokuqala ephosakeleyo. Akukho nanye 'ingcono' wax; imalunga newax efanelekileyo yomsebenzi othile-ipateni yakho entsokothileyo, ingxubevange oyigalelayo, imozulu yevenkile yakho, kunye nomjikelo wakho wokudinwa. Ndibone abantu abaninzi abafikayo be-odola i-wax 'yepremiyamu' esekwe kwi-specs kuphela, kuphela ukuba baphele beneepateni eziqhekekileyo okanye intsalela yothuthu olubi. Olona khetho luvela ekuqondeni urhwebo.
IiMpawu ezingundoqo: Eyona nto uyifunayo
Zilibale iilebhile zegeneric. Uvavanya umxube. Iipropati eziphambili zizinzo lwe-dimensional (akufuneki ukuba lujike ubusuku bonke), umxholo wothuthu oluphantsi (olubalulekileyo kwimingxuma ecocekileyo kwi-alloys ye-high-temp), kunye neempawu ezintle zokukrola / zomatshini ukuba wenza ukulungiswa okanye ukulinganisa ngokuthe ngqo. Iwax eqine kakhulu inokuba brittle kwaye kube nzima ukuyisango; enye ethambileyo kakhulu iya kuwela kwiqokobhe okanye ikhubazeke phantsi kobunzima bayo kwindibano yomthi. Ndidla ngokuzihlela ngokwenkqubo ephambili: inaliti, umfuziselo/ukufakela, kunye nokudipha.
Isitofu, ukuhamba kunye nesantya sokuncipha yiyo yonke into. Iwax kufuneka igcwalise ukungunda ngokupheleleyo kwaye emva koko icuthe ngokuqikelelwa kude kuyo ukuze isuswe lula. Ndineziphumo ezilungileyo ngemixube ethile elungisiweyo yeparafini-microcrystalline. Banikezela ngokulinganisela okulungileyo. Iinyosi esulungekileyo, ehlala ithandeka, ithambile kwaye iyaguquguquka kuninzi lomsebenzi wemveliso, nangona ithandeka kumaqhekeza athile obugcisa apho ukusebenza kwezandla kubaluleke kakhulu.
Umxholo womlotha awunakuxoxisana malunga nokuchithwa okuchanekileyo, ngakumbi kwi-aerospace okanye izicelo zonyango apho nayiphi na intsalela inokudala ukubandakanywa. Ezinye ii-wax ezenziwe nge-polymer-based wax ziqhayisa ngokusondeleyo-zero uthuthu, nto leyo emnandi, kodwa inokuba liphupha lokususa kwisixhobo ukuba bafika kwindawo abangafanelanga ukuba baye kuyo. Sisenzo esisoloko silungelelanisa.
Isitofu vs. Isilo esakhiwe ngesandla: Irhamncwa elahlukileyo lilonke
Umthwebeba owusebenzisa kumatshini wokutofa ngokuzenzekelayo sisilwanyana esahlukileyo kwibhloko oyiqingqayo okanye ishiti olithi nkxu. Iiwax zoomatshini zenzelwe amaqondo obushushu athile kunye noxinzelelo. Kwivenkile yam yangaphambili, sasebenzisa inaliti eluhlaza ephakathi-lukhuni evela kumthengisi omkhulu womsebenzi wethu wentsimbi engenasici. Yayithembekile. Kodwa xa sithatha umsebenzi ofuna amacandelo abhityileyo kakhulu ecandelo leinjini yomoya, ayiphumelelanga—yaphola ngokukhawuleza yaza yadala imigca ebalekayo. Siye satshintshela kwisimo esithambileyo, esisezantsi se-viscosity kunye nobushushu obuphezulu benaliti, obusombulule umba wokuzalisa kodwa emva koko kwafuna ukuba siphathe iipateni ngononophelo olukhulu ngakumbi ngexesha lokuhlanganisa. Lonke utshintsho luyakhula.
Kumsebenzi wezandla, njengokuchwetheza i-seams okanye izinto zokwakha, ndigcina iindidi ezimbini ebhentshini: incangathi, 'i-wax encamathelayo' yokudibanisa ngokukhawuleza kunye 'newax yesixhobo' esiqingqiwe ngakumbi sokuzalisa kunye nokubumba. Iwax encangathi ngokuyimfuneko yiglu elawulwayo. I-wax yesixhobo kufuneka ibenzima ngokwaneleyo ukuze ibambe i-edge ekrwada xa uyikhuhla kodwa ithambe ngokwaneleyo ukuze igudiswe ngemela eshushu. Ndifumana eyam kubaboneleli abakhethekileyo abambalwa; eyona nto ibalulekileyo ibhrendi ibalulekile ngaphantsi kokungaguquguquki kwayo ukusuka kwibhetshi ukuya kwibhetshi.
Uvavanyo lwehlabathi lokwenyani: Ukutshiswa kulapho iNyaniso izityhila khona
Uyakwazi ukuthanda i-wax kwibhentshi, kodwa i-oven evuthayo ngumgwebi wokugqibela. Ukunyibilika okucocekileyo, okupheleleyo yinjongo. Ezinye iiwax, ngakumbi ezo zinomxholo ophezulu wokuzalisa, zinokushiya inkani, intsalela ye-tarry ethintela ukuhamba kodaka kwiqokobhe elilandelayo okanye, ngakumbi, ishiya iziphene zekhabhoni kwintsimbi yokugqibela. Oku ndakufunda kabuhlungu kwasekuqaleni. Besisebenzisa iwax efikelelekayo, eyenjongo gabalala ukulungiselela izifakelo zentsimbi yekhabhoni. Iicastings zahlala ziphuma kunye ne-surface pitting. Emva kokulawula udaka kunye nemiba yesinyithi, siyilandelele emva kwintsalela yewax encibilika ekubumbeni. Utshintshele kwi-wax enothuthu oluphantsi, kwaye ingxaki yaphela. Iindleko ngekhilogram beziphezulu, kodwa izinga lokulahlwa lehla.
Ukongezelelwa komjikelo wokutshiswa kubotshelelwe kwiwax yakho. Iishedyuli eziqhelekileyo ze-ramp-and-hold kwi-furnace manuals ziqala iindawo zokuqala. Ngomxube omtsha we-wax, sihlala siqhuba iigobolondo ezimbalwa zovavanyo kunye ne-thermocouples ukuze sibone indlela eziphatha ngayo. Ngaba iyanda kakhulu ngexesha lokuqala lokufudumala, ibeka umngcipheko wokuqhekeka kweqokobhe? Ngaba iguquka ngokupheleleyo ngobushushu obujoliswe kuko? Olu lungelelwaniso lwezandla yinto ongayifumaniyo kwidatabase.
Izinto eziphathekayo: Kutheni i-alloy yakho ichaphazela ukhetho lwakho lwe-wax
Le yingongoma edla ngokutyeshelwa. Ingxubevange oyiphosayo iyalela ngaphezulu kwerefractory yeqokobhe. Ukugalela i-nickel-based superalloy yobushushu obuphezulu? Udinga i-wax enomxholo ophantsi kakhulu wothuthu kuba ezo zibumba zitshiswa kumaqondo obushushu agqithisileyo, kwaye nayiphi na intsalela iya kubhaka kwi-ceramic. Kwiialloyi zobushushu obuphantsi obufana nobhedu okanye ialuminiyam, unendlela ethe chatha, kwaye izinto ezifana neendleko kunye nokulula kosetyenziso zinokuqala.
Iinkampani eziphethe uluhlu olubanzi lwezixhobo, ezifana Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), esebenza ukusuka kwintsimbi etyhidiweyo ukuya kwi-cobalt kunye ne-nickel-based alloys, mhlawumbi igcina ithala leencwadi elincinci le-wax. Awunakusebenzisa ukwakheka kwewax efanayo kwi-iron manifold elula kunye nokufakelwa koqhaqho oluchanekileyo. Iminyaka yabo engamashumi amathathu iqokobhe ngundo ukuphosa kwaye utyalo mali ngebezibeke kwimingeni emininzi enxulumene nomthwebeba. Ukhetho luba yinxalenye yobunjineli benkqubo kwicandelo ngalinye. Ndingabheja amagcisa abo anezimvo ezinamandla malunga nokuba iwax isebenza ngcono kwiinkqubo zabo zeqokobhe kunye nezenzo zokudinwa, ulwazi olwakhiwe ngokubona amawaka obumba angena kwiziko.
Iingqwalasela eziSebenzayo ngaPhaya kwePhepha leDatha
Ukugcinwa kunye nokuphatha kukhulu. Iiweksi ziyabuva ubushushu. Iphalethi eshiywe kwisikhongozeli senqanawa esishushu inokuba bubugxwayiba obudityanisiweyo. Eyethu siyigcina kwigumbi elilawulwa yimozulu. Nangona kunjalo, umswakama wonyaka unokuchaphazela umgangatho weepateni ngexesha lokuhlanganisana, okudinga uhlengahlengiso kwinkqubo yokukhupha. Zezi nyaniso ziqhelekileyo, ezikumgangatho wevenkile ezichaza 'eyona nto ibhetele' ngaphezu kwalo naluphi na uvavanyo elebhu.
Emva koko kukho ukuthembeka komthengisi. Ngaba umxube uyahambelana ukusuka kwi-oda ukuya kwi-odolo? Ngaba inkxaso yobugcisa iluncedo xa unengxaki? Ndibambene nomthengisi hayi ngenxa yokuba i-wax yabo yayiphezulu ngomlingo, kodwa ngenxa yokuba imveliso yabo yayiqikelelwa kwangaphambili kwaye i-rep yabo inokujongana nam ngefowuni. Kwishedyuli yemveliso, uqikelelo lukholisa ukuba nexabiso ngakumbi kunenzuzo yokusebenza kancinci kwiwax 'egqwesileyo' engavavanywanga.
Ngoko, ingcebiso yam? Qala ngewax ehloniphekileyo, ekumgangatho weshishini lomsebenzi wakho ophambili. Gcina i-wax yemodeli ethembekileyo esandleni. Emva koko, ulinge. Odola iibhetshi ezincinci zeentlobo ezahlukeneyo zokuqhuba uvavanyo. Bhala iziphumo-hayi nje ukuphosa, kodwa indlela eziphathe ngayo kwinqanaba ngalinye. Eyona 'wax ingcono' yileyo ithi shwaka kwinkqubo yakho, ikushiye ungenanto yokucinga ngayo ngaphandle kweqokobhe eligqibeleleyo elilungele isinyithi. Nantso injongo. Incinci malunga nemveliso kwaye ngaphezulu malunga nokuphumeza imeko apho izinto ziyayeka ukuguquguquka. Kulapho uyazi ukuba umfumene umntu odibana naye.
