Wakambosangana nemamiriro ezvinhu aya here? Zvikamu zvesimbi zvezvigadziriso zvemwenje zvawakatenga zvinotanga kuratidza zviratidzo zvekuora pamusoro pepamusoro mushure menguva yekushandiswa. Izvi zvinonyatsoratidza kuti mhando yezvigadzirwa zvekuvhenekesa zvakadaro haisi kusvika pachiyero. Kana iwe uchida kuziva nezve chikonzero chiri shure kweizvi, saka nhasi ticharatidza kuti zvese zvine hukama ne "munyu kupfapfaidza kuyerwa"!
Chii chinonzi Salt Spray Test?
Salt Spray Test muyedzo wezvakatipoteredza unoshandiswa kuongorora kusakara kwezvigadzirwa kana simbi zvinhu. Inotevedzera nzvimbo yekupfapfaidza munyu kuti iongorore kusimba kwezvinhu pasi pemamiriro ezvinhu akadaro uye kuongorora maitiro avo uye hupenyu hurefu munzvimbo dzinoparadza.
Kuongorora Kuronga:
1. Neutral Salt Spray (NSS)
Neutral Salt Spray Test ndiyo yekutanga uye yakanyanya kushandiswa yakakwirisa corrosion test nzira. Kazhinji, inoshandisa 5% sodium chloride mvura yemunyu ine pH value yakagadziridzwa kuita kwayakarerekera (6.5-7.2) yekushandisa spray. Tembiricha yekuyedza inochengetedzwa pa35°C, uye mwero wemunyu wekuisa mhute unodiwa kuva pakati pe1-3 ml/80cm²·h, kazhinji 1-2 ml/80cm²·h.
2. Acetic Acid Salt Spray (AASS)
Acetic Acid Salt Spray Test yakagadzirwa kubva kuNeutral Salt Spray Test. Zvinosanganisira kuwedzera glacial acetic acid kune 5% sodium chloride mhinduro, kudzikisa pH kusvika kutenderera 3, zvichiita kuti mhinduro ive acidic, uye zvichizoshandura mhute yemunyu kubva kune kwayakarerekera kuita acidic. Kuora kwayo kunokurumidza kupeta katatu kupfuura kuongororwa kweNSS.
3. Copper Accelerated Acetic Acid Salt Spray (CASS)
Copper Accelerated Acetic Acid Salt Spray Test ichangobva kugadzirwa nekukurumidza munyu yekupfapfaidza corrosion test kunze kwenyika. Iyo tembiricha yekuyedza ndeye 50 ° C, ine shoma shoma yemunyu yemhangura (copper chloride) inowedzerwa kune munyu mhinduro, iyo inokurumidza kukurumidza kuora. Kuora kwayo kunosvika kasere nekukurumidza kupfuura kuyedzwa kweNSS.
4. Alternating Salt Spray (ASS)
Alternating Salt Spray Test muyedzo wakakwana wemunyu wekupfapfaidza unobatanidza kusapira munyu kupfapfaidza nekusagara kunyorova. Iyo inonyanya kushandiswa kune mhango-mhando-yakazara-muchina zvigadzirwa, inducing munyu pfapfaidzo corrosion kwete chete pamusoro pechigadzirwa asiwo nechomukati kuburikidza nekupinda kwemamiriro ehunyoro. Zvigadzirwa zvinochinjana matenderedzwa pakati pemunyu mhute uye humidity, kuongorora shanduko mumagetsi nemakanika mashandiro ezvigadzirwa zvemuchina wese.
Zvigadzirwa zvekuvhenekesa zveLiper zvakare zvakapfapfaidzwa nemunyu zvakaedzwa here?
Mhinduro ndeyokuti Hongu! Zvigadzirwa zvesimbi zveLiper zvemarambi uye zvivheneko zvinogadzirwa zvinoenderana nepasi rose. Zvichienderana neiyo IEC60068-2-52 yakajairwa, ivo vanopinda muyedzo yekukasira yecorrosion inosanganisira kuenderera mberi kwekupfapfaidza kwemaawa gumi nemaviri (yesimbi yekuisa). Mushure mekuedzwa, zvigadzirwa zvedu zvesimbi hazvifanirwe kuratidza zviratidzo zveoxidation kana ngura. Ipapo chete ndipo panogona kuedzwa zvigadzirwa zvemwenje zveLiper uye zvinokodzera.
Tinovimba kuti chinyorwa ichi chinobatsira vatengi vedu kunzwisisa kukosha kwekupfapfaidza munyu. Pakusarudza zvigadzirwa zvekuvhenekesa, zvakakosha kuti usarudze sarudzo dzemhando yepamusoro. PaLiper, zvigadzirwa zvedu zvinoedzwa zvakaomarara, zvinosanganisira bvunzo dzekupfapfaidza munyu, bvunzo dzehupenyu, bvunzo dzisina mvura, uye kubatanidza sphere bvunzo, nezvimwe.
Aya akakwana emhando cheki anovimbisa kuti vatengi veLiper vanogashira zvemhando yepamusoro, zvigadzirwa zvemwenje zvinovimbika, nekudaro zvichisimudzira hupenyu hwemutengi wedu uye kugutsikana kwese.
Senyanzvi yekugadzira mwenje, Liper ine hungwaru pakusarudza zvinhu, ichikutendera iwe kusarudza uye kushandisa zvigadzirwa zvedu nechivimbo.
