Ulwazi oluncane lwe-InterWeighing:
Kusukela ngo-1995, i-China Weighing Instrument Association ihlele imicimbi engu-20 ye-InterWeighing e-Beijing, e-Chengdu, e-Shanghai, e-Hangzhou, e-Qingdao, e-Changsha, e-Nanjing, e-Guangdong Dongguan nase-Wuhan. Inqwaba yabakhiqizi abaziwayo babambe iqhaza kule micimbi njengababonisi. Ochwepheshe abaningi nabathengi abavela e-Asia, Europe, America, Oceania nase-Afrika bavakashele le mibukiso. Le mibukiso izuze idumela elihle okuqhubeka nokugqugquzela ukuhwebelana kwamazwe ngamazwe kanye nokusebenzisana emikhakheni yokukala umnotho nobuchwepheshe.
Ngemuva kweminyaka yokutshala ngokucophelela, isikali nomthelela we-InterWeighing ukhula kancane kancane. Namuhla, i-InterWeighing isiphenduke umbukiso wethuluzi lokukala elisezingeni eliphezulu kakhulu emhlabeni wonke futhi eliphakeme kunawo wonke. Umcimbi waminyaka yonke we-InterWeighing usuphenduke umcimbi omkhulu waminyaka yonke wezimboni emhlabeni. I-InterWeighing iqinise ukuhwebelana kwezomnotho nezobuchwepheshe kanye nokusebenzisana phakathi kwemibuthano yamazwe omhlaba yokukala isisindo, futhi ikhuthaze ngokusizayo ukuthuthukiswa kohwebo lwemikhiqizo enesisindo emhlabeni wonke. Ngaphezu kokuba senkingeni yezimali emhlabeni wonke ngo-2009 kwaba nokwehla kancane, ukuthunyelwa kwemikhiqizo ekalayo eChina minyaka yonke kukhuphuka ngezinga lokukhula elihle. Ngo-2018, ngokwezibalo ze-China Customs, ukuthunyelwa kwemikhiqizo enesisindo kufinyelele ku-USD1.398 billion; inyuke ngo-5.2% kunowezi-2017.
Isizathu esenza izinsimbi zensimbi engagqwali zimelane nokugqwala
UJiajia uphinde wabamba iqhaza embukisweni wezimboni we-INTERWEIGHING ngo-2020 futhi.
Ngenxa yalolu bhubhane, nakuba abangane abaningi bamazwe ngamazwe abakwazanga ukubamba iqhaza emcimbini waminyaka yonke wezimboni, sisadlulisela ulwazi lombukiso kuwo wonke amakhasimende nge-inthanethi, okuhlanganisa nobuchwepheshe obusha, imikhiqizo emisha, kanye nezitayela zokuthuthukiswa kwezimboni.
Isikhathi esikhethekile siphinde sasilethela amathuba engeziwe okuxhumana nabaphakeli abafanayo bezimboni. Funda mayelana nobuchwepheshe obusha kanye nentuthuko embonini. Kuxoxwe ngethrendi yomkhiqizo wesikhathi esizayo kanye nentuthuko nabo ndawonye. Ngaphansi kwesimo semakethe esisha, imikhiqizo izothuthukiswa kakhulu, okuzovumela amabhizinisi ukwenza kahle imikhiqizo kanye nokucwaninga ngemikhiqizo esezingeni eliphezulu yezimakethe ezahlukene. Ngaphansi kwesisekelo sokugxila ekuhlangenwe nakho kwamakhasimende, sizokwenza imikhiqizo ibe kahle futhi inemininingwane. Kokubili mayelana nokusebenza, ukuphepha kanye nekhwalithi kungcono.
Izinsimbi zensimbi ezingenasici zinezici zokumelana nokugqwala, okunciphisa iphutha lezisindo ngesikhathi sokusebenzisa. Khona-ke kungani insimbi engagqwali inezici zokumelana nokugqwala okwengeziwe? Ochwepheshe bezinsimbi zensimbi engagqwali bazokuchazela.
Njengoba kushiwo encwadini yekhemistri yesikole samabanga aphezulu, zonke izinsimbi zisabela ngamakhemikhali nomoya-mpilo osemkhathini ukuze zenze ifilimu ye-oxide ebusweni bento. I-oxide eyakhiwe phezu kwe-carbon steel evamile ibhekana nokusabela kwe-oxidation, bese ukugqwala kukhuliswa kancane kancane, futhi ekugcineni kwakheka imbobo yensimbi. Kufanele kwenziwe kanjani lokhu? Ngokuvamile, indlela wonke umuntu ayisebenzisayo ukusebenzisa upende noma insimbi engamelana ne-oxide ukuze kuvikelwe i-electroplating, ukuze i-oxide engaphezulu kwensimbi ingabi lula ukucekelwa phansi. Ukumelana nokugqwala kwensimbi engagqwali kubangelwa kakhulu ukuba khona kwe-trace element, okungukuthi, i-chromium, engenye yezingxenye zensimbi.
Lapho okuqukethwe kwe-chromium kufinyelela ku-11.7%, ukumelana nokugqwala kwensimbi engagqwali kukhuphuka kakhulu, okuthuthukisa ukumelana nokugqwala. Akukhona nje kuphela ukuthi okuqukethwe kwe-chromium kunyukile, i-oxidation eyakhiwe i-chromium nensimbi inamathela endaweni yensimbi, engamelana nokugqwala futhi ivimbele i-oxidation. . Ngokuvamile, umbala wemvelo wendawo yensimbi ungabonakala nge-oxide yensimbi, futhi indawo yensimbi engagqwali iyindawo eyingqayizivele. Ngaphezu kwalokho, ngisho noma indawo engaphezulu ilimele, insimbi evezwe emoyeni izokwakha ifilimu yokuzivikela enezendlalelo ezimbili nomkhathi, owaziwa nangokuthi ifilimu yesibili yokudlula, eqhubeka nokuvikelwa okwesibili, ngaleyo ndlela ifeze injongo ukumelana nokugqwala.
Siyakwamukela yonke imikhakha yempilo ku-Yantai Jiajia Instrument ukuze uthenge izisindo zensimbi engagqwali, ngoba ziwuchwepheshe futhi zithembekile.
