Shanghai Chun Ye "yakazvipira kuzvinhu zvinobatsira zvakatipoteredza muhupfumi hwezvakatipoteredza" nechinangwa chebasa.Bhizinesi rinonyanya kutarisa pamudziyo wekudzora mashandiro emaindasitiri, mudziyo wekutarisa otomatiki wemhando yemvura online, VOCs (votile organic compounds) system yekutarisa online uye TVOC online monitoring alarm system, Internet of Things data acquisition, transmission and control terminal, CEMS smoke continuous monitoring system, guruva noise online monitoring system, air monitoring nezvimwe zvigadzirwa R&D, kugadzirwa, kutengesa uye sevhisi.
Pfupiso yeChigadzirwa
Dzidziso huru yepHkuyerwa kweelectrode ndikoNernst equation. Masensa anoshandiswa mukuongorora kwepotentiometric anonzi galvanic cells. Sero regalvanic sisitimu inoshandura simba remakemikari kuita simba remagetsi. Voltage yesero iri inonzi electromotive force (EMF). Iyi electromotive force (EMF) ine masero maviri nehafu. Sero rimwe nehafu rinonzi measuring sensors, uye kugona kwavo kwakabatana nebasa reion rakati; Rimwe sero rehafu ireferensi yehafu yesero, inowanzonzi reference sensor, iyo inowanzo taurirana nemhinduro yekuyera uye yakabatana nemudziyo wekuyera.
ORP(REDOX potential) chiratidzo chakakosha muhunhu hwemvura. Kunyangwe isingakwanise kuratidza hunhu hwemvura yoga, inogona kubatanidza zvimwe zviratidzo zvehunhu hwemvura kuti iratidze nharaunda yezvakatipoteredza muhurongwa hwe aquarium.
Mumvura, chinhu chimwe nechimwe chine zvachinorevaZvivakwa zveREDOXNemashoko akareruka, tinogona kunzwisisa kuti: padanho re micro, chinhu chimwe nechimwe chakasiyana chine simba rekuderedza oxidation, uye zvinhu izvi zvine hunhu hwakasiyana hwekuderedza oxidation zvinogona kukanganisana, uye pakupedzisira zvinoumba hunhu hwakasiyana hwekuderedza oxidation. Iyo inonzi REDOX potential inoshandiswa kuratidza hunhu hwekuderedza oxidation hwezvinhu zvese zviri mumhinduro yemvuraKana mukana weREDOX wakakwira,kusimba kwe oxidation, kana simba remagetsi rakaderera, ndipo panobva simba remagetsi rakaderera. Positive potential inoratidza kuti mhinduro inoratidza oxidation, uye negative potential inoratidza kuti mhinduro yachoinoratidza kudzikira.
Kubatana kweElectrode
Kuti ubatanidze electrode yepH/ORP kune chishandiso, electrode ine tembiricha inofanirawo kubatanidza terminal yetembiricha kune chishandiso, uye kusarudza chirongwa chekuripa tembiricha chinoenderana nacho pachinhu chacho.
Dhayagiramu yekuisa
① Kuisa madziro emativi: iva nechokwadi chekuti kona yekona yekona yakakuratembiricha iri pasi pe15 degrees;
② Kuiswa kweflange yepamusoro:teerera saizi yeflangeuye kudzika kwekuisa maerekitirodhi;
③ Kuiswa kwepaipi:teerera dhayamita yepombi, mwero wekuyerera kwemvura uye kumanikidzwa kwepombi;
④Kuiswa kwekuyerera: teerera mwero wekuyerera kwemvura uye kumanikidzwa kwemvura;
⑤ Kuiswa kwemvura yakanyura:teerera kureba kwerutsigiro.
Kugadziriswa nekugadzirisa maerekitirodhi
Pakushandisa electrode, chivharo chekudzivirira electrode chinofanira kutanga chabviswa, uyegirobhu remagetsi nechikamu chemvura zvinofanirwa kunyikwa mumvura yakayerwa.
Kana zvikawanikwa kutimakristaro emunyuzvinoumbwa mumusoro we electrode uye chifukidziro chekudzivirira nekuda kwekubuda kwe electrolyte mukati me electrode kuburikidza ne dialysis film, hazvikanganisi kushandiswa kwakajairika kwe electrode, zvichiratidza kuti electrode dialysis film yakajairika, uye inogonayakagezwa nemvura.
Cherechedza kanamune mabhuru mugirobhu regirazi, unogona kubata mugumo wepamusoro weelectrode wozunza kashoma.
Kuti ive nechokwadi chekuti mhinduro inokurumidza, firimu regirazi remagetsi rinofanira kugara rakanyorova, uye mushure mekuyerwa kana kuenzaniswa, magetsi anofanira kucheneswa nemazvo uye huwandu hwakati hwemvura yekudzivirira magetsi hunofanira kudonhedzwa muchivharo chekudzivirira magetsi. Mhinduro yekuchengetera yaive 3mol/L potassium chloride solution.
Tarisa kana magumo e electrode akaoma. Kana paine mavara, pukuta nedoro risina mvura wobva wapukuta usati washandisa.
Kunyudzwa mumvura yakacheneswa kana mapuroteni kwenguva refu kunofanira kudzivirirwa, uyeKusangana nemafuta e-silicone kunofanira kudzivirirwa.
Kana electrode ikashandiswa kwenguva yakareba, girazi rayo rinogona kupenya kana kuva ne deposits, izvo zvinogonakushambidzwa ne 10% hydrochloric acid yakasanganiswa nemvuraZvinokurudzirwa kuti mushandisi achenese electrode nguva nenguva uye aigadzirise nemudziyo.
Kana electrode isingakwanise kugadziriswa uye kuyerwa zvakajairika mushure mekugadzirisa nekuchengetedza electrode uchishandisa nzira dziri pamusoro, electrode haigone kudzoreredza mhinduro yayo, ndapota tsiva electrode.
