Ulwazi oluncane lwe-InterWeighing:
Kusukela ngo-1995, i-China Weighing Instrument Association ihlele imicimbi engu-20 ye-InterWeighing eBeijing, eChengdu, eShanghai, eHangzhou, eQingdao, eChangsha, eNanjing, eGuangdong Dongguan naseWuhan. Abakhiqizi abaningi abadumile bahlanganyele kule micimbi njengababonisi. Ochwepheshe abaningi nabathengi abavela e-Asia, eYurophu, eMelika, e-Oceania nase-Afrika bavakashele le mibukiso. Le mibukiso yathola idumela elihle elikhuthaza kakhulu ukushintshana kwamazwe ngamazwe kanye nokusebenzisana emikhakheni yokulinganisa umnotho kanye nobuchwepheshe.
Ngemva kweminyaka eminingi yokulima ngokucophelela, ubukhulu kanye nethonya le-InterWeighing kuye kwanda kancane kancane. Namuhla, i-InterWeighing isibe umbukiso wezinsimbi zokulinganisa zobungcweti omkhulu kunayo yonke emhlabeni futhi osezingeni eliphezulu emhlabeni jikelele. Umcimbi waminyaka yonke we-InterWeighing usube ngumcimbi wemboni omkhulu kunayo yonke emhlabeni. I-InterWeighing iqinise ukushintshana kwezomnotho kanye nobuchwepheshe kanye nokubambisana phakathi kwezimboni zokulinganisa zamazwe ngamazwe, futhi isize ekukhuthazeni intuthuko yokuhweba ngemikhiqizo yokulinganisa emhlabeni jikelele. Ngaphezu kokuba enkingeni yezezimali yomhlaba wonke ka-2009 kube nokwehla okuncane, ukuthunyelwa kwemikhiqizo yokulinganisa minyaka yonke eShayina kwanda ngesivinini sokukhula esihle. Ngo-2018, ngokusho kwezibalo ze-China Customs, ukuthunyelwa kwemikhiqizo yokulinganisa kufinyelele ku-USD1.398 billion; kukhuphuke ngo-5.2% kuno-2017.
Isizathu sokuthi izisindo zensimbi engagqwali zingamelani nokugqwala
UJiajia waphinde wabamba iqhaza embukisweni wemboni ye-INTERWEIGHING ngo-2020.
Ngenxa yalolu bhubhane, nakuba abangani abaningi bamazwe ngamazwe bengakwazi ukuhlanganyela emcimbini waminyaka yonke wemboni, sisadlulisela ulwazi lombukiso kuwo wonke amakhasimende nge-inthanethi, okuhlanganisa ubuchwepheshe obusha, imikhiqizo emisha, kanye nezitayela zokuthuthukiswa kwemboni.
Isikhathi esikhethekile sisilethele namathuba engeziwe okuxhumana nabahlinzeki bezimboni abafanayo. Funda ngobuchwepheshe obusha kanye nentuthuko embonini. Sixoxe ngomkhuba wesikhathi esizayo kanye nentuthuko nabo ndawonye. Ngaphansi kwendawo entsha yemakethe, imikhiqizo izothuthukiswa kakhulu, okuzoba ngcono kakhulu ekwakhiweni kwemikhiqizo okuhle kwamabhizinisi nokucwaninga ngemikhiqizo ephezulu kakhulu yezimakethe ezahlukene. Ngaphansi kwesisekelo sokugxila kokuhlangenwe nakho kwamakhasimende, sizokwenza imikhiqizo ibe mihle futhi ibe nemininingwane. Kokubili maqondana nokusebenza, ukuphepha kanye nekhwalithi kungcono.
Izisindo zensimbi engagqwali zinezici zokumelana nokugqwala, okunciphisa iphutha lezisindo enkambisweni yokusetshenziswa. Pho kungani insimbi engagqwali inezici zokumelana nokugqwala okwengeziwe? Ochwepheshe bezisindo zensimbi engagqwali bazochaza kuwe.
Njengoba kushiwo encwadini yesayensi yamakhemikhali yesikole samabanga aphezulu, zonke izinsimbi zisabela ngamakhemikhali nomoya-mpilo emoyeni ukuze zakhe ifilimu ye-oxide ebusweni bento. I-oxide eyakhiwe ebusweni bensimbi yekhabhoni evamile ibhekana nokusabela kwe-oxidation, bese ukugqwala kwandiswa kancane kancane, bese ekugcineni kwakheka imbobo yensimbi. Lokhu kufanele kwenziwe kanjani? Ngokuvamile, indlela wonke umuntu ayisebenzisayo ukusebenzisa upende noma insimbi engamelani ne-oxide ukuvikela i-electroplating, ukuze i-oxide ebusweni bensimbi ingabi lula ukubhujiswa. Ukumelana nokugqwala kwensimbi engagqwali kubangelwa kakhulu ukuba khona kwe-trace element, okungukuthi, i-chromium, nayo engenye yezingxenye zensimbi.
Uma okuqukethwe kwe-chromium kufinyelela ku-11.7%, ukumelana nokugqwala kwensimbi engagqwali kuyanda kakhulu, okuthuthukisa ukumelana nokugqwala. Akukhona nje kuphela ukuthi okuqukethwe kwe-chromium kuyanda, kodwa futhi ukugqwala okwakhiwa yi-chromium nensimbi kunamathela ebusweni bensimbi, okungamelana nokugqwala futhi kuvimbele ukugqwala. Ngokuvamile, umbala wemvelo wobuso bensimbi ungabonakala nge-oxide yensimbi, kanti ubuso bensimbi engagqwali buyindawo eyingqayizivele. Ngaphezu kwalokho, noma ngabe ubuso bonakalisiwe, insimbi evezwe emoyeni izokwakha ifilimu yokuvikela enezingqimba ezimbili enomoya, owaziwa nangokuthi ifilimu yesibili yokudlula, eqhubeka nokuvikelwa okwesibili, ngaleyo ndlela kufezwe injongo yokumelana nokugqwala.
Siyakwamukela zonke izindlela zokuphila eYantai Jiajia Instrument ukuze uthenge izisindo zensimbi engagqwali, ngoba zinobungcweti futhi zithembekile.
