| Nzvimbo dzinonyoroveswa (kusuka, kubvisa tsvina, kupwanya ganda) | Yakakwira: mvura inogumira, 85-95% RH, kusvibiswa kwesanitizer zuva nezuva | SS304 yakaputirwa (chisimbiso chegirazi kubva pasimbi kuenda pagirazi, ndinotsanangura izvi sezvinodiwa) | Apa ndipo pandakaona zvisimbiso zve epoxy zvichikundikana mukati memwedzi gumi nemiviri. Chisimbiso chegirazi-kuva-simbi hachigone kutaurwa nezvacho mumashoko angu enzvimbo idzi. Ndakadzidza izvi zvakanditorera mari yewaranti muna 2020 - kubva pandakachinja kuenda kuzvisimbiso zve hermetic, handina kumbobvira ndawana hunyoro munzvimbo dzakanyorova. |
| Nzvimbo dzeCIP / washdown (spray yakananga yekuchenesa) | Zvakanyanya: kusangana zvakananga ne100-200 ppm NaOCl, peracetic acid, QACs; kupisa cycling ka4-6 pazuva | SS316 yakaputirwa (chisimbiso chegirazi-ku-simbi, PREN ≥ 24) | Iyi ndiyo nzvimbo yakaoma zvikuru yandinotaura pakugadzira chikafu. Molybdenum iri muSS316 inodiwa — Ndakayera kurwiswa kwepamusoro kweSS304 munzvimbo dzeCIP mushure memwedzi gumi nemisere. Ndakatsanangurawo ukobvu hwemadziro hunosvika 1.5 mm uye 316L weld filler yemakona ese akagadzirwa nemabhuraketi munzvimbo idzi. |
| Nzvimbo yegungwa/ine munyu wakawanda (miti iri mukati memakiromita mashanu kubva kugungwa) | Kuwedzera kwekushushikana kwe chloride inobuda mumhepo | SS316 yenzvimbo dzese, zvisinei nekuoma kwemaitiro | Ndinoyera chloride inoiswa mumhepo pa50-200 mg/m²/zuva panzvimbo dziri kumahombekombe muVietnam neThailand. Izvi zvinowedzera corrosion stress iyo SS304 yangu munzvimbo dziri kumahombekombe yakaratidza kuti yakabatana ne weld seams mukati memwedzi makumi maviri nemana. Kuvandudzwa kweSS316 kunowedzera inenge 15-20% pazvinhu zvekupisa, uye ndinoiona seinishuwarenzi yakachipa yandinogona kutenga maneja wezvivakwa zvemahombekombe. |
Ndinowana mubvunzo mumwe chete kubva kune maneja wese wekutenga:"Sei tisingataure SS316 kwese kwese?" Mhinduro yacho ndeyekuti mari inodzorwa. Kune vanochengeta zvinhu mufiriji nekushandisa mufiriji, SS316 haina pundutso inoyerwa - kuwedzera 15-20% pamutengo wekushanda usingashandiswe kupambadza matsananguro akawandisa.
Ndinokurudzira kuisa chivakwa chako munzvimbo nhanhatu dziri pamusoro apa uye kushandisa mari yakatarwa yemakore mashanu. Munzvimbo dzinopfuura makumi mana dzandakaisa, hybrid specification inopa aluminium foil ku20-30% yenzvimbo, SS304 ku50-60%, uye SS316 ku10-20%. Mari yakaiswa inoderera ne40-60% pasi penzira yeUniversal-SS316, ine kuvimbika kwakaenzana. Ndinoongorora specifications sechikamu chega chegapurojekiti yechinhu chekupisa chakagadzirwa nemaokoNdinobvuma — ndichatevera hurongwa humwe chete nemi uye ndichakupai mazano angu echokwadi neruzivo rwebasa runotsigira.
