Indima Ebalulekile Yokuqhumisa I-White Fused Aluminium Sandblasting Ekwelashweni Kwensimbi Ngaphambi Kokwelashwa
Labo kithi kulo mkhakha bayazi ukuthi izingxenye zensimbi, njengabantu, zidinga ukulungiswa okuphelele ngaphambi kokuya ukuyohlangana nezivakashi. Uma zimbozwe ngamafutha, ukugqwala, nopende omdala, wonke umuntu uzonikina amakhanda. Isinyathelo sokuqala kulokhu "kulungiswa" ukwelashwa kwangaphambili, futhi ukuqhumisa isihlabathi se-aluminium esimhlophe esihlanganisiwe kungumdlali obalulekile kule nqubo. Namuhla, sizoyichaza futhi sixoxe ngokuthi le nto idlala kanjani indima yayo engenakuphikwa ekuphathweni kwensimbi kwangaphambili.
I. Akuyona Yonke “Isihlabathi” Esiyi-White Fused Aluminium: Yini Eyenza Ibe Namandla Kangaka?
Abasanda kufika embonini bangase bacabange ukuthi ukuqhuma kwesihlabathi kuwukusebenzisa isihlabathi ukushaya indawo yensimbi, yini ekhethekile ngakho? Nokho, lowo umbono ongenangqondo kakhulu. Zama ukusebenzisa isihlabathi somfula noma isihlabathi se-quartz? Lezo zinto aziqinile ngokwanele, zikhiqiza uthuli oluningi, zimbi empilweni yabasebenzi, futhi zivame ukushiya insalela ebusweni ngemva kokuqhuma. I-alumina emhlophe ehlanganisiwe ihlukile; inguchwepheshe weqiniso.
Cabanga ngakho:i-alumina emhlophe ehlanganisiweiyi-corundum yokwenziwa, imsulwa kakhulu, futhi njengoba nje igama layo lisho, imhlophe qwa. Kodwa iqine kakhulu! Ubulukhuni bayo buphakathi kwezinto ezisusa kakhulu, ilandela i-silicon carbide nedayimane. Lokhu kusho ukuthi uma ithinta izindawo zensimbi, isebenza kahle kakhulu, isika imfucumfucu exubene ngesivinini sombani.
Ngaphezu kwalokho, izinzile kakhulu ngamakhemikhali, ayinayo i-silicon yamahhala, futhi uthuli lwayo lungcono kakhulu emaphashini. Ikhiqiza izinhlayiya ezinobukhulu obufanayo, ngokungafani nezinye izinto ezisusa uthuli ezingadala ukuphela okuqinile. Okubaluleke kakhulu, ayidonsi uthuli noma ukungcola; ihlala ihlanzekile futhi ngeke ifake ukungcola ebusweni bensimbi, okuyinto ebaluleke kakhulu lapho kufakwa izembozo noma i-plating kamuva. Ngakho-ke, ukuyikhetha njengento yokuqala kunikeza ukuthula kwengqondo.
II. Indlela Yayo Enezinhlangothi Ezintathu: Ukuhlanza, Ukuhlanza, Nokuqinisa
Ukuqhuma kwe-alumina okumhlophe okuxutshwe kugxile kakhulu ezinqubweni ezintathu eziyinhloko zangaphambi kokwelashwa: ukuhlanza, ukuhluza, kanye nokuqinisa. Ake sixoxe ngazo ngayinye ngayinye.
Iphiko Lokuqala: Ukuhlanza Okuphelele, Akushiyi Nkinga Kamuva
Lokhu kuyinto eyisisekelo kakhulu, kodwa futhi edinga kakhulu. Izingxenye zensimbi ezivela emshinini wensimbi, noma ezigcinwe endaweni yokugcina impahla isikhathi eside, zinobuso obufana "nesikhwama esixubile" sangempela: isikali se-oxide (ukugqwala okuluhlaza okwesibhakabhaka noma okubomvu ngokunsundu), i-welding slag, amabala kawoyela aqinile, izembozo ezindala… Ukugeza nge-chemical acid akuyona into engenakwenzeka, kodwa akulungile emvelweni futhi kungase kudle ngisho ne-substrate. Ukugaya ngesandla ngesondo lensimbi? Lokho akusebenzanga kahle kakhulu.
Ukuqhumisa i-alumina emhlophe ehlanganisiwe akunandaba nalokho. Kuqhutshwa ukucindezela okuphezulu kwe-air compressor, izigidi zezinhlayiya ezincane ze-alumina ezimhlophe ezihlanganisiwe, njengezinhlamvu, "whoosh," zibheke endaweni yokusebenza. Lokhu akuyona nje into yokukhafula; inqubo yangempela yokukhumula ebonakalayo. Isikali se-oxide kanye ne-slag yokuwelda ayilutho ngaphandle "kwama-tiger ephepha" lapho ikhona, aqhekeke ngokushesha futhi aqhekeke. Ngemva kokufutha, bheka futhi! Umbala wensimbi wemvelo uyavezwa, uhlanzekile futhi uqinile, njenge-tofu esanda kwenziwa—umbono ojabulisayo. Lesi sinyathelo sokuqala sokuhlanza sifana nokulungiselela "ikhanvasi" ehlanzekile yezinqubo ezilandelayo.
Izembe Lesibili: Ukubhoboza Okuhle, Ukubamba Uboya
Ingabe ukuhlanza kwanele? Cha! Cabanga ngendawo yensimbi ebushelelezi, efana nesibuko; uma uyifaka upende noma uyimboza nge-powder, ingabe ukunamathela kuzoba kuhle? Kufana nokunamathisela iphephandaba engilazini—kuzowa uma uthinta kancane. Isimanga sesibili sokuqhumisa isihlabathi se-corundum esimhlophe “ukusilungisa” le ndawo ebushelelezi.
Akubhubhisi, kodwa kunalokho “izithombe eziqoshiwe.” Kudala imigodi eminingi emincane kakhulu, efanayo ebusweni bensimbi, esiyibiza ngokuthi “amaphethini e-anchor” noma “ukurhabaxa.” Ungayithathi kalula le migodi; yandisa kakhulu indawo engaphezulu, njengokunikeza isembozo “ngezandla” ezincane eziyizinkulungwane, ezisibamba ngokuqinile. Lokhu kuphumela ekwandeni kwejiyometri ekunamatheleni kwefilimu yopende kanye nongqimba lwepulasitiki, okwenza kungabi lula ukuqhekezeka noma ukuqhekeka. Lo mphumela wokurhabaxa, olinganiswa ngamathuluzi ochwepheshe “njengokurhabaxa,” yinto ingcweti enolwazi engayisho ngokushesha ngokuthinta: “Hmm, lo msebenzi wenziwe kahle, upende unamathela kahle!”
Isinyathelo Sesithathu: Ukuqinisa Okungabonakali, Ukwandisa Isikhathi Sokuphila
Lesi sinyathelo sesithathu sifana kancane “namandla angaphakathi”—angabonakali futhi awaphatheki, kodwa izinzuzo zingokoqobo. Umthelela wesivinini esikhulu wezinhlayiya ezimhlophe ze-corundum ebusweni bensimbi empeleni inqubo “yokusebenza ngokubandayo”. Kubangela ukuphambuka kwe-lattice ebusweni bensimbi, okudala ukucindezeleka okucindezelayo.
Kuyini ukucindezeleka okucindezelayo? Cabanga ngakho kanje: kufana nokubeka "i-bodysuit engabonakali" ebusweni bensimbi, okwenza isakhiwo sama-molecule sento sibe sincane futhi siqine. Lokhu kwandisa amandla okukhathala kwensimbi futhi kuthuthukisa ukumelana kwayo nokugqwala kokucindezeleka, kwandise ngempumelelo isikhathi sokuphila komsebenzi. Kwezinye izingxenye ezibalulekile, njenge-crankshafts yenjini kanye negiya lokufika lendiza, le nqubo ibaluleke kakhulu.
III. Ikhwalithi Yomsebenzi Incike Endleleni Owusebenzisa Ngayo
Imishini ngokwayo ingase ibe mihle, kodwa ukuze umsebenzi wenziwe kahle, konke kuncike endleleni oyisebenzisa ngayo. Kunezindlela eziningi zokuyisebenzisa.
Okokuqala, udinga ukukhetha i-grit efanele. I-grit emaqhubu inezinzuzo zayo, kanti i-grit encane inezinzuzo zayo. Uma ufuna ukususa ukugqwala okukhulu noma upende, udinga ukusebenzisa i-grit emaqhubu, njenge-mesh engu-20 noma engu-30, ukuze uthole amandla engeziwe. Uma ufuna kuphela ukuhlanza kahle noma iphethini ye-anchor ethambile kakhulu, udinga ukusebenzisa i-grit enciphile, njenge-mesh engu-80 noma engu-100. Awukwazi ukusebenzisa isihlabathi esifanayo kukho konke.
Okwesibili, udinga ukulawula umfutho womoya kanye ne-engeli. Uma umfutho womoya uphansi kakhulu, i-abrasive izoba mnene kakhulu futhi ibuthakathaka; uma umfutho womoya uphakeme kakhulu, ingaguqula kalula izinto zokusebenza ezincane noma iphule i-abrasive, okuholela emiphumeleni emibi. Lokhu kusebenza nase-engeli yesibhamu sokufafaza. Ekuhlanzeni okuvamile, i-engeli engama-degrees angu-45 kuya kwangu-70 ifaneleka kakhulu. Uma i-engeli incane kakhulu, kuba “njengokukhuhla umhlabathi,” okuholela emiphumeleni engalingani.
Okokugcina, indawo ezungezile kumele igcinwe yomile.I-alumina emhlophe ehlanganisiweMuhle ngazo zonke izindlela, ngaphandle kokuthi “uzwela kancane kumswakama.” Uma usumanzi, uhlangana kalula, uvale umlomo wesibhamu sokufafaza, okungabangela ukubambezeleka okukhulu. Ngakho-ke, umthombo wethu womoya kumele ufakwe isihlukanisi samanzi kawoyela, futhi ithangi lokugcina isihlabathi kumele livikelwe emswakama.
Ngakho-ke, ngicela ungacabangi nge-alumina emhlophe ehlanganisiweukuqhuma kwesihlabathinjengomsebenzi olula "wokuhlanza". Emkhakheni wokulungisa insimbi kusengaphambili, iyindlela ephelele, esebenza "njengomhlanzi," "umqophi," kanye "nokuqinisa." Ikhiqiza imiphumela ehlanzekile, efanayo, futhi enamathela kahle, futhi "iqinisa" izingxenye zensimbi, ibeka isisekelo esiphelele sezinqubo ezilandelayo njengokufafaza, ukufaka i-electroplating, kanye nokushisela. Emsebenzini wezimboni, sikholelwa ukuthi "isisekelo esibuthakathaka siholela ekungazinzini." Lokhu kulungisa kusengaphambili "kuyisisekelo" sawo wonke umsebenzi omuhle. Ukusebenzisa i-white fused alumina sandblasting kahle kungase kubonakale njengesinyathelo esengeziwe enkambisweni, kodwa empeleni konga imali eningi ekuvuseleleni nasekulungiseni kamuva. Kuyisivumelwano esifanelekile kungakhathaliseki ukuthi usibheka kanjani! Kufana "nenkabi endala" ethule kodwa ethembekile kakhulu ekulungiseni insimbi kusengaphambili, engalokothi ikudumaze lapho kubaluleke kakhulu.
