Ruzivo rudiki rweInterWeighing:
Kubva muna 1995, China Weighing Instrument Association yakaronga zviitiko makumi maviri zveInterWeighing muBeijing, Chengdu, Shanghai, Hangzhou, Qingdao, Changsha, Nanjing, Guangdong Dongguan neWuhan. Vagadziri vakawanda vanozivikanwa vakapinda muzviitiko izvi sevaratidziri. Nyanzvi dzakawanda nevatengi vanobva kuAsia, Europe, America, Oceania neAfrica vakashanyira zviratidziro izvi. Zviratidziro izvi zvakawana mukurumbira wakanaka izvo zvinosimudzira kudyidzana kwenyika dzakawanda pamwe nekushandira pamwe muminda yekuyera hupfumi netekinoroji.
Mushure memakore ekurima nekungwarira, kukura uye pesvedzero yeInterWeighing yave ichikura zvishoma nezvishoma. Nhasi, InterWeighing yave kuratidzwa kwezvishandiso zvekuyera zvehunyanzvi zvemhando yepamusoro uye zvepamusoro-soro pasi rose. Chiitiko chegore negore cheInterWeighing chave chiitiko chikuru chegore negore cheindasitiri pasi rose. InterWeighing yakasimbisa kuchinjana kwehupfumi netekinoroji uye kushandira pamwe pakati pemaindasitiri ekuyera epasi rose, uye yakabatsira kukurudzira kuvandudzwa kwekutengeserana kwezvigadzirwa zvekuyera zvepasi rose. Kuwedzera pakuva mudambudziko remari repasi rose ra2009 paive nekuderera kudiki, kutengeswa kwezvigadzirwa zvekuyera zvepagore neChina kunowedzera nekukura kwakanaka. Muna 2018, zvichienderana nehuwandu hweChina Customs, kutengeswa kwezvinhu zvekuyera kunze kwenyika kwasvika USD1.398 bhiriyoni; kwakawedzera ne5.2% kupfuura 2017.
Chikonzero nei zviremerera zvesimbi isina ngura zvisingapindi ngura
Jiajia akapindawo muchirongwa cheINTERWEIGHING muna 2020 zvakare.
Nekuda kwedenda iri, kunyangwe shamwari zhinji dzepasi rose dzisina kukwanisa kutora chikamu muchiitiko chegore negore cheindasitiri, takaenderera mberi nekupa ruzivo rwechiratidziro kune mutengi wese kuburikidza neInternet, kusanganisira matekinoroji matsva, zvigadzirwa zvitsva, uye mafambiro ekuvandudza indasitiri.
Nguva yakakosha iyi yakatiunzirawo mikana yakawanda yekutaurirana nevatengesi vemaindasitiri vamwe chete. Dzidza nezve matekinoroji matsva nekuvandudzwa muindasitiri. Takakurukura nezvemafambiro ezvigadzirwa zvemangwana pamwe chete navo. Pasi pemamiriro matsva emusika, zvigadzirwa zvicharamba zvichinyatsogadziriswa, izvo zvichabatsira mabhizinesi kugadzira zvigadzirwa zvakanaka uye kutsvaga zvigadzirwa zvepamusoro-soro zvemisika yakasiyana. Tichitarisa pane ruzivo rwevatengi, tichaita kuti zvigadzirwa zvive zvakanaka uye zvakadzama. Zvese zviri zviviri maererano nekushanda, kuchengetedzeka uye mhando zviri nani.
Zviremu zvesimbi isina ngura zvine hunhu hwekudzivirira ngura, izvo zvinoderedza kukanganisa kwezviremu pakushandiswa. Saka sei simbi isina ngura iine hunhu hwekudzivirira ngura zvakanyanya? Nyanzvi dzezviremu zvesimbi isina ngura dzichakutsanangurira.
Sezvambotaurwa mubhuku rekemesitiri rechikoro chesekondari, simbi dzese dzinoita makemikari pamwe chete neokisijeni mumhepo kuti dzigadzire oxide film pamusoro pechinhu chacho. Okisijeni inoumbwa pamusoro pesimbi yakajairwa inobatwa ne oxidation reaction, uye ngura inowedzerwa zvishoma nezvishoma, uye pakupedzisira gomba resimbi rinoumbwa. Izvi zvinofanira kuitwa sei? Kazhinji, nzira inoshandiswa nemunhu wese ndeyekushandisa pendi kana simbi isingapindi oxide kudzivirira electroplating, kuitira kuti oxide iri pamusoro pesimbi isaparadzwe nyore. Kuramba ngura kwesimbi isingapindi ngura kunokonzerwa nekuvapo kwechinhu chinoratidza trace element, kureva chromium, iyo iriwo chimwe chezvinhu zvesimbi.
Kana huwandu hwechromium hwasvika 11.7%, kuramba ngura kwesimbi isingatsvi kunowedzera zvakanyanya, izvo zvinovandudza kuramba ngura. Hazvisi chete kuti huwandu hwechromium hunowedzerwa, asi kuoxidation kunoumbwa nechromium nesimbi kunonamatira pamusoro pesimbi, izvo zvinogona kuramba ngura uye kudzivirira kuoxidation. Kazhinji, ruvara rwechisikigo rwesimbi runogona kuonekwa kuburikidza nesimbi inonzi oxide, uye pamusoro pesimbi isingatsvi chinhu chakasiyana. Uyezve, kunyangwe pamusoro pakakuvara, simbi inoburitswa mumhepo inoumba firimu rekudzivirira rine mativi maviri rine mhepo, inozivikanwawo sefirimu rechipiri repassivation, iro rinoramba richidzivirirwa kechipiri, nokudaro richizadzisa chinangwa chekudzivirira ngura.
Tinokugamuchirai mose kuYantai Jiajia Instrument kuti mutenge zviremerera zvesimbi isingatsvi, nekuti zvine hunyanzvi uye zvinovimbika.
