Uma othile asesha 'i-wax ehamba phambili yokusakazwa kwe-wax elahlekile', ngokuvamile unethemba lempendulo elula, enosayizi owodwa olingana-konke. Lowo umbono oyiphutha wokuqala. Ayikho neyodwa ingcina 'engcono kakhulu'; kumayelana nengcina efanele yomsebenzi othile—iphethini yakho eyinkimbinkimbi, ingxubevange oyithelayo, isimo sezulu sesitolo sakho, ngisho nomjikelezo wakho wokutubeka. Ngibone abaningi abasanda kufika be-oda i-'premium' wax esekelwe ku-specs kuphela, kuphela bagcine sebenamaphethini aqhekekile noma izinsalela zomlotha ezimbi. Inketho yangempela ivela ekuqondeni ukuhwebelana.
Izimfanelo Eziyinhloko: Lokho Okufunayo Empeleni
Khohlwa amalebula ajwayelekile. Uhlola ukuhlanganisa. Izakhiwo eziyinhloko ukuzinza kwe-dimensional (akufanele igoqe ngobusuku obubodwa), okuqukethwe komlotha ophansi (okubalulekile emigodini ehlanzekile kuma-alloys ashisa kakhulu), kanye nezakhiwo ezinhle zokuqopha/zomshini uma ulungisa noma umodela ngokuqondile. I-wax eqinile kakhulu ingaba brittle futhi kube nzima ukuyifaka; eyodwa ethambile kakhulu izowa egobolondweni noma ibole ngaphansi kwesisindo sayo emhlanganweni wesihlahla. Ngivame ukuzibeka ngokwezigaba ngohlelo lokusebenza lokuqala: umjovo, ukumodela/ukuchibiyela, kanye nokudipha.
Ngomjovo, izinga lokugeleza nokufinyela liyikho konke. I-wax idinga ukugcwalisa isikhunta ngokuphelele bese incipha ngokubikezela ukuthi isuke kuyo ukuze isuswe kalula. Ngibe nemiphumela emihle ngezingxube ezithile eziguquliwe zikapharafini-microcrystalline. Banikeza ibhalansi enhle. Ingcina yezinyosi emsulwa, evame ukwenziwa ibe yothando, ivamise ukuthamba kakhulu futhi iyaguquguquka emisebenzini eminingi yokukhiqiza, nakuba ithandeka kwezinye izingcezu zobuciko lapho ukusebenza kwezandla kubaluleke kakhulu.
Okuqukethwe komlotha akuxoxiswana ngakho mayelana nokusakazwa okunembayo, ikakhulukazi ku-aerospace noma izinhlelo zokusebenza zezokwelapha lapho noma iyiphi insalela ingadala ukufakwa. Amanye ama-wax asuselwa ku-polymer okwenziwa aqhosha ngomlotha ocishe ube nguziro, okuyinto enhle, kodwa angaba yiphupho elibi ukuwasusa ezintweni zokusebenza uma efika endaweni okungafanele afinyelele kuyo. Kuyisenzo sokulinganisa njalo.
Umjovo vs. Owenziwe Ngesandla: Isilwane Esihlukile Sisonke
I-wax oyisebenzisa emshinini wokujova othomathikhi iyisilwane esihlukile kunebhulokhi oyiqophayo noma ishidi oligcobhozayo. Ama-wax omshini aklanyelwe amazinga okushisa athile nezingcindezi. Esitolo sami sangaphambilini, sasebenzisa umjovo oluhlaza okotshani oqinile ophakathi nendawo ovela kumnikezeli omkhulu wemisebenzi yethu eminingi yensimbi engagqwali. Yayithembekile. Kodwa lapho sithatha umsebenzi odinga izingxenye ezincane kakhulu zengxenye ye-turbine, yehluleka—yaphola ngokushesha futhi yakha imigqa yokugeleza. Sishintshele ekwakhiweni okuthambile, okune-viscosity ephansi enezinga lokushisa eliphezulu lomjovo, okuxazulule inkinga yokugcwalisa kodwa kwase kudingwa ukuthi siphathe amaphethini ngokunakekela okukhulu phakathi nokuhlanganisa. Lonke ushintsho luyahamba.
Ngomsebenzi wezandla, njengokuphetshwa imithungo noma izici zokwakha, ngigcina izinhlobo ezimbili ebhentshini: 'i-wax enamathelayo' enamathelayo, ethambileyo yokuhlanganisa ngokushesha kanye 'ne-wax yamathuluzi' eqina kakhulu, ebaziwe kakhulu yokugcwalisa nokulolonga. I-wax enamathelayo empeleni iyiglue elawulwayo. I-wax yamathuluzi idinga ukuba lukhuni ngokwanele ukuze ibambe unqenqema oluhlanzekile uma uyiklwebha kodwa ithambe ngokwanele ukuze yenziwe bushelelezi ngommese ofudumele. Ngithola okwami kubahlinzeki abambalwa abakhethekile; uhlobo oluqondile lubalulekile ngaphansi kokungaguquguquki kwalo kusuka kuqoqo kuye kwinqwaba.
Ukuhlolwa Komhlaba Wangempela: Ukushiswa Yilapho Iqiniso Liziveza Khona
Ungakwazi ukuthanda i-wax ebhentshini, kodwa ihhavini elivuthayo liyijaji lokugcina. Ukuncibilika okuhlanzekile, okuphelele kungumgomo. Amanye ama-wax, ikakhulukazi lawo anokuqukethwe okuphezulu kokugcwalisa, angashiya insalela enenkani, evimbe ukugeleza kwe-slurry kungqimba lwegobolondo elilandelayo noma, okubi nakakhulu, kushiye amaphutha ekhabhoni ensimbi yokugcina. Lokhu ngakufunda kabuhlungu kusenesikhathi. Besisebenzisa i-wax eshibhile, eyenhloso evamile ekufakweni kwensimbi ye-carbon. Ama-castings ayelokhu ephuma nge-surface pitting. Ngemva kokunquma ukuthi akukho zinkinga ze-slurry nensimbi, sakulandelela emuva ekusaleni kwe-wax ekubunjweni. Kushintshelwe kungcina enomlotha omncane, futhi inkinga yashabalala. Izindleko ngekhilogremu beziphezulu, kodwa izinga le-scrap lehla.
Ukwenza ngcono umjikelezo wokushiswa kuhlanganiswe nengcina yakho. Amashejuli avamile we-ramp-and-hold kumanuwali esithandweni asanda kuqala. Ngenhlanganisela entsha ye-wax, sihlala siqhuba amagobolondo ambalwa okuhlola ngama-thermocouples ukuze sibone ukuthi iziphatha kanjani. Ingabe inweba kakhulu ngesikhathi sokufudumala kokuqala, ibeka engcupheni ukuqhekeka kwegobolondo? Ingabe ishintshashintsha ngokugcwele ngezinga lokushisa eliqondiwe? Lokhu kushuna okwenziwa ngesandla yinto ongayitholi kumininingwane.
Izinto Ezibalulekile: Kungani I-alloy Yakho Ithonya Ukukhetha Kwakho Kwe-wax
Leli yiphuzu elivame ukunganakwa. Ingxubevange oyisakazayo isho okungaphezu nje kwe-refractory yegobolondo. Ukuthela i-superalloy esekelwe ku-nickel ephezulu? Udinga i-wax enomlotha ophansi kakhulu ngoba lezo zikhunta zishiswa emazingeni okushisa aphezulu, futhi noma iyiphi insalela izobhaka ku-ceramic. Kuma-alloy wezinga lokushisa eliphansi njengethusi noma i-aluminium, unokukhululeka okwengeziwe, futhi izici ezifana nezindleko nokusebenziseka kalula zingase zize kuqala.
Izinkampani eziphatha inhlobonhlobo yezinto zokwakha, njenge I-Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), esebenza kusukela kunsimbi ewukhonkolo kuya ku-cobalt nama-alloys ane-nickel, cishe igcina umtapo omncane wama-wax. Awukwazi ukusebenzisa ukwakheka okufanayo kwe-wax ku-iron manifold elula kanye nokufakelwa okunembayo kokuhlinzwa. Iminyaka yabo engamashumi amathathu ukubunjwa kwegobolondo futhi ukutshala imali bekungabachaya ezinseleleni ezingenakubalwa ezihlobene nengcina. Ukukhetha kuba yingxenye yenqubo yobunjiniyela engxenyeni ngayinye. Ngingabheja ochwepheshe babo banemibono eqinile yokuthi iyiphi i-wax esebenza kangcono kumasistimu abo amagobolondo kanye nemikhuba yokutubeka, ulwazi olwakhiwe ngokubona izinkulungwane zesikhunta sidlula esithandweni somlilo.
Ukucatshangelwa Okusebenzayo Ngale Kweshidi Ledatha
Isitoreji nokuphatha kukhulu. Ama-wax azwela ukushisa. Iphalethi elishiywe esitsheni semikhumbi esishisayo lingaba isiphithiphithi esihlanganisiwe. Okwethu sikubeka ekamelweni elilawulwa yisimo sezulu. Ngisho nangaleso sikhathi, umswakama wonyaka ungathinta ingaphezulu lamaphethini ngesikhathi sokuhlangana, okudinga ukulungiswa enqubweni ye-dewaxing. Yilezi zimo ezivamile, zesitezi sesitolo ezichaza 'okungcono kakhulu' kunanoma yikuphi ukuhlolwa kwelebhu.
Bese kuba khona ukuthembeka komphakeli. Ingabe ukuhlanganisa kuyahambisana kusuka ku-oda kuye kwelinye? Ingabe usekelo lobuchwepheshe luwusizo uma unenkinga? Nginamathele kumhlinzeki hhayi ngoba i-wax yakhe ibiphakeme ngokumangalisayo, kodwa ngenxa yokuthi umkhiqizo wabo wawubikezelwe futhi ummeli wakhe angangixazulula inkinga ngocingo. Kushejuli yokukhiqiza, ukubikezela ngokuvamile kubaluleke kakhulu kunenzuzo yokusebenza kancane evela ku-wax 'engcono kakhulu' engahloliwe.
Ngakho, iseluleko sami? Qala ngomjovo we-wax ohlonishwayo, osezingeni lomkhakha womsebenzi wakho oyinhloko. Gcina i-wax yemodeli ethembekile esandleni. Bese, ukuhlola. Oda amaqoqo amancane ezinhlobo ezahlukene ukuze uthole imigijimo yokuhlola. Bhala imiphumela—hhayi nje ukulingisa, kodwa indlela okuziphathe ngayo esinyathelweni ngasinye. 'I-wax ehamba phambili' yileyo enyamalalayo ohlelweni lwakho, ikushiye ungenalutho ongacabanga ngakho ngaphandle kwegobolondo eliphelele elilungele insimbi. Yilokho umgomo. Kuncane ngomkhiqizo futhi kumayelana nokuzuza isimo lapho okokusebenza kuyeka ukuguquguquka. Kulapho-ke owazi khona ukuthi umtholile owafanelana naye.
