Ithimba locwaningo nentuthuko e-AMETEK Specialty Metal Products (SMP) - elizinze e-Eighty Four, PA, US, libe nesithakazelo emandleni avelayo epulasitiki.Ibhizinisi litshale isikhathi nezinsiza ekuguquleni izimpushana zalo ezinengxubevange ephezulu kanye nensimbi engagqwali zibe izithasiselo ezifanele noma izinto zokugcwalisa ukuze zisetshenziswe ezinhlelweni ezimbalwa, okuhlanganisa izinhlanganisela zepulasitiki ezitholakalayo zokukhiqiza ukudla kanye nokukhiqizwa kwemithi kanye namapulasitiki anobunjiniyela besizukulwane esilandelayo.
Njengoba ukuphatha ukudla kuba yinkimbinkimbi ngokwengeziwe ukuze kuhlangatshezwane nesidingo somphakathi sokuhlanzeka, izithasiselo ezingena kumapulasitiki kulezi zicelo kumele zenze ezingeni elikhulayo.Okulindelekile kwezithasiselo zepulasitiki ukuthi umkhiqizo manje usuzoxutshwa kalula futhi umiswe epulasitikini noma ezintweni ze-epoxy ezisetshenziselwa ukwenza izingxenye zokugcina noma ezinenani elingenasici.Izingxenye zokugcina kufanele zikhiqizwe ngemibala enembile kanye namabanga epulasitiki ukuze zifane nophawu olukhona ngaphambili, imibala eyingozi, noma imihlahlandlela yokuphepha kokudla kuyilapho ngesikhathi esifanayo kunikelwa izakhiwo ezikhuphuke kakhulu.Isibonelo, amapulasitiki aluhlaza okwesibhakabhaka atholakalayo akhiqizwa ngezithako eziphakeme zensimbi manje avamile ezindaweni zokukhiqiza ukudla neziphuzo futhi avumela ukuhlonza izingcezu zepulasitiki ezincane.
UBrad Richards, uMphathi Womkhiqizo we-AMETEK SMP Eighty Four, uyachaza ngokuqhubekayo: “Ukuletha izimpushana zethu zensimbi engagqwali eziklanyelwe ngokukhethekile njengezithasiselo ezitholakalayo zamapulasitiki kunikeza izinzuzo eziningi.Ukungcola kokudla nesiphuzo kuyancishiswa njengoba izingcezu zepulasitiki ezingabonakali noma zizwakale ngaphakathi kwento manje sezibonakala kalula emishinini ye-X-ray noma ngokutholwa kazibuthe.Lokhu kukhulisa kakhulu ikhwalithi yabakhiqizi ngokunikeza amandla abalulekile okunciphisa ukungcola nokunamathela emithethweni eqinile yezimboni mayelana nekhwalithi yokudla nesiphuzo, ukuphepha, nokuphatha.”
Le mithetho ihlanganisa imithetho eqinile e-UK, Europe, nase-US I-US FDA Food Safety Modernization Act (FSMA) kanye nomthetho womkhandlu waseYurophu EU 10/2011, isibonelo, zombili zidinga ukuqaliswa kwezilawuli ezivimbela ukungcoliswa kwepulasitiki kwemikhiqizo yokudla.Lokhu kuye kwaholela ekuthuthukisweni kobuchwepheshe bokubona ngamasistimu e-X-ray, kodwa futhi nasekuthuthukisweni kokubonwa kazibuthe kanye ne-X-ray yamapulasitiki ngokwawo uma kuqhathaniswa nokudla nemikhiqizo yesiphuzo.Isicelo esivamile esivela kulo mthetho ukusetshenziswa kwezithasiselo zensimbi engagqwali ezenziwe nge-athomu yamanzi kumapulasitiki, njengoba akhiqizwa i-AMETEK SMP futhi echazwe ngu-Richards ngenhla, ukwandisa kakhulu ukuhluka kwe-X-ray nokuvumela ukutholakala kalula kwepulasitiki.
Izithasiselo zensimbi zinikeza izinzuzo zezinye izingxenye zepulasitiki ezenziwe ngobunjiniyela kanye nama-polymer compounders futhi.Lokhu kufaka phakathi ukudambisa ukudlidliza, okuphumela ekuhlanganiseni okubalulekile okunokunwebeka, ukuminyana, kanye nezakhiwo zokuncishiswa kokudlidliza ezingashintshwa zonke kububanzi obubanzi.Ezinye izinhlanganisela zezithasiselo zethu zensimbi nazo zingakhuphula ukuqhutshwa kukagesi kwento yonke, kudale ukwanda kwezakhiwo ezilwa ne-anti-static noma ze-conductive ekulayishweni okuphezulu.
Kubandakanya izinhlayiya zensimbi eziqinile ezintweni ezaziwa njengezinhlanganisela ze-polymer matrix kuholela emkhiqizweni onamandla onikeza ukumelana nokugqokwa okungcono nokuphila okusebenzisekayo okwandisiwe.
URichards uyachaza ngokuqhubekayo: “Ukufakwa kwezithasiselo zethu zensimbi kunikeza umfutho kulawo makhasimende enza amapulasitiki amaningi obunjiniyela bezobuchwepheshe.Ukwenyuka kokuqina, ukuhuzuka, kanye nezakhiwo ezimelana nokuguguleka kuzenza zibe nezinto ezihlukahlukene kakhulu futhi zilungele ukusetshenziswa okubanzi.Singakwazi ukwandisa conductivity ezishisayo kanye kagesi futhi kalula ukuguqula ukuminyana impahla.Singakwazi futhi ukwenza izingxenye zepulasitiki ezikwazi ukushisisa ngokufakwa, okuyindawo eyingqayizivele nefunwayo njengoba ivumela ukushisisa okusheshayo nokufana okufanayo kwezingxenye ngazinye.”
I-AMETEK SMP ikhiqiza izimpushana zensimbi kusukela ku-300 no-400 ochungechungeni lwezinsimbi ezingenasici ngebanga lokucolisekileyo (~30 µm) nosayizi abamahhadla (~100 µm) njengezithasiselo nezigcwalisi zezinhlanganisela ze-polymer.Ama-alloys angokwezifiso namasayizi angenziwa efanelana nezicaciso eziqondile zekhasimende zezidingo ezihlukene zokukhiqiza.Amamaki amane ahlukene ezimpushana zensimbi engagqwali ye-AMETEK SMP sezivamile: 316L, 304L, 430L, kanye nama-alloys angu-410L.Konke kuklanywe ngokukhethekile ngezigaba zosayizi onembile ukuze kuhlanganiswe kangcono nezithasiselo ze-polymer.
Izimpushana zensimbi ezisezingeni eliphakeme zenziwe yi-AMETEK SMP iminyaka engama-50.Izinsiza ezithuthukisiwe, ezihlanganisa ubuchwepheshe be-atomization yamanzi anomfutho ophezulu, zenza ibhizinisi linikeze amazinga aphezulu okwenza ngokwezifiso.Onjiniyela be-AMETEK SMP kanye nama-metallurgists basebenza namakhasimende ukubonisana ngezincomo zomkhiqizo nokukhetha kwezinto ezibonakalayo.Amakhasimende angakhetha ingxubevange okuyiyonayona, usayizi wezinhlayiyana, kanye nokuma ukuze kuqinisekiswe umphumela onembe kakhulu ukuze kuhlangatshezwane nezidingo zekhwalithi ezifunwa kakhulu zomkhakha wokudla, owekhemisi, wezokuvikela nowezimoto.
