Ulwazi oluncinci lwe-InterWeighing:
Ukususela kwi-1995, i-China Weighing Instrument Association iququzelele iziganeko ze-20 ze-InterWeighing e-Beijing, e-Chengdu, e-Shanghai, e-Hangzhou, e-Qingdao, e-Changsha, e-Nanjing, e-Guangdong Dongguan nase-Wuhan. Uninzi lwabavelisi abaziwayo bathathe inxaxheba kwezi ziganeko njengababonisi. Iingcali ezininzi kunye nabathengi abavela e-Asiya, eYurophu, eMelika, e-Oceania nase-Afrika batyelele le miboniso. Le miboniso iye yazuza isidima esihle nto leyo ekhuthaza ngakumbi utshintshiselwano lwamazwe ngamazwe kunye nentsebenziswano kumacandelo ovavanyo lwezoqoqosho nobuchwepheshe.
Emva kweminyaka yokulima ngononophelo, isikali kunye nefuthe le-InterWeighing ziye zakhula ngokuthe ngcembe. Namhlanje, i-InterWeighing ibe ngowona mboniso mkhulu kunye nowona mgangatho uphezulu wesixhobo sokulinganisa ubuchwephesha ehlabathini. Umnyhadala wonyaka we-InterWeighing uye waba ngowona msitho mkhulu wonyaka woshishino kwihlabathi. I-InterWeighing yomelezile utshintshiselwano lwezoqoqosho kunye nobuchwepheshe kunye nentsebenziswano phakathi kwezangqa zeshishini lokukala lamazwe ngamazwe, kwaye ikhuthaze ngokuluncedo uphuhliso lorhwebo lwemveliso yokulinganisa yehlabathi. Ukongeza kubunzima bemali behlabathi bowama-2009 bekukho ukuhla okuncinci, ukuthunyelwa kwemveliso yaseTshayina kumazwe angaphandle ngonyaka konyuka ngesantya sokukhula esihle. Kwi-2018, ngokwezibalo ze-China Customs, ukuthunyelwa ngaphandle kweemveliso zokulinganisa kuye kwafikelela kwi-USD1.398 billion; inyuke nge-5.2% kunowama-2017.
Isizathu sokuba iintsimbi zentsimbi zinganyangeki kwi-corrosion
UJiajia uthathe inxaxheba kumboniso weshishini we-INTERWEIGHING ngo-2020 kwakhona.
Ngenxa yobhubhani, nangona abahlobo abaninzi bamazwe ngamazwe bengazange bakwazi ukuthatha inxaxheba kumsitho wonyaka woshishino, sisadlulisa ulwazi lwalo mboniso kuye wonke umthengi nge-Intanethi, kuquka ubugcisa obutsha, iimveliso ezintsha, kunye neendlela zophuhliso lweshishini.
Ixesha elikhethekileyo likwasizisele amathuba amaninzi okunxibelelana nabanikezeli bemizi-mveliso abafanayo. Funda malunga nobuchwepheshe obutsha kunye nophuhliso kushishino. Kuxoxwe ngentsingiselo yemveliso yexesha elizayo kunye nophuhliso kunye nabo kunye. Phantsi kommandla omtsha wentengiso, iimveliso ziya kuphucuka ngakumbi nangakumbi, nto leyo eya kuba luncedo ngakumbi kushishino lobuchule bokwenza iimveliso kunye nophando lweemveliso ezikumgangatho ophezulu kwiimarike ezahlukeneyo. Ngaphantsi kwesiseko sokugxila kumava omthengi, siya kwenza iimveliso kakuhle kunye neenkcukacha. Zombini ngokubhekiselele ekusebenzeni, ukhuseleko kunye nomgangatho ungcono.
Izisindo zensimbi ezingenasici zineempawu zokumelana ne-corrosion, okunciphisa impazamo yobunzima kwinkqubo yokusetyenziswa. Ke kutheni insimbi engenasici ineempawu zokumelana nokugqwala? Iingcali zeentsimbi zensimbi ezingenasici ziya kukuchazela.
Njengoko kukhankanyiwe kwi-junior high school chemistry textbook, zonke isinyithi zisabela ngokwekhemikhali kunye neoksijini emoyeni ukuze zenze ifilimu ye-oxide kumphezulu wento. Ioksidi eyenziwe kumphezulu wekhabhoni yentsimbi eqhelekileyo ifumana i-oxidation reaction, kwaye ke umhlwa uyandiswa kancinci kancinci, kwaye ekugqibeleni kwenziwa umngxuma wesinyithi. Kufanele kwenziwe njani oku? Ngokuqhelekileyo, indlela wonke umntu ayisebenzisayo kukusebenzisa ipeyinti okanye i-oxide-resistant metal yokukhusela i-electroplating, ukuze i-oxide kwindawo yesinyithi ingabi lula ukutshatyalaliswa. Ukuxhatshazwa kwe-corrosion yensimbi engenasici kubangelwa ubukhulu becala kubukho be-trace element, oko kukuthi, i-chromium, ekwayenye yamacandelo ensimbi.
Xa umxholo we-chromium ufikelela kwi-11.7%, ukuxhatshazwa kwe-corrosion yensimbi engenasici kwanda kakhulu, okuphucula ukuxhathisa kwe-corrosion. Akunjalo kuphela umxholo we-chromium owandisiweyo, i-oxidation eyenziwe yi-chromium kunye nentsimbi ibambelela kwi-metal surface, enokumelana nokubola kunye nokukhusela i-oxidation. . Ngokuqhelekileyo, umbala wendalo wentsimbi ungabonwa nge-oxide yensimbi, kwaye i-stainless steel surface yindawo ekhethekileyo. Ngaphezu koko, nokuba umphezulu wonakele, intsimbi evezwe emoyeni iya kwenza ifilimu ekhuselayo enemigangatho emibini kunye ne-atmosfera, eyaziwa ngokuba yifilimu ye-secondary passivation film, eqhubeka ikhuselwa okwesibini, ngaloo ndlela ifezekisa injongo ukumelana nomhlwa.
Wamkelekile kuzo zonke iinkalo zobomi kwi-Yantai Jiajia Instrument ukuze uthenge iintsimbi zentsimbi engenasici, kuba ziyingcali kwaye zithembekile.
