[/prisna-wp-translate-show-hidInkqubo yokukhusela kunye nokuhlobisa umphezulu weemveliso zentsimbi, ezinokunciphisa kunye nokuphepha ukubola komphezulu wesinyithi kwaye iphinde idlale indima yokuhombisa, ibizwa ngokuba kukukhuselwa komphezulu kunye nokuhombisa iimveliso zentsimbi. Kwiimveliso zentsimbi, indlela yonyango ebanzi yokukhusela umphezulu kunye nokuhlobisa ngokuqhelekileyo yamkelwa. Zininzi iindlela zonyango ezikhethekileyo, kodwa kwiimveliso zentsimbi, ezo zisetyenziswa ngokuqhelekileyo kukutyabeka kunye ne-electroplating (i-hot plating). Ukuba zombini zisetyenziswa kunye, yeyona ilungileyo yokuqina.
1. Umaleko ongeyontsimbi okhuselayo: Faka enye okanye ngaphezulu kweekhompawundi ze-organic kunye ne-inorganic, njengepeyinti, iplastiki, irabha, i-asphalt, i-enamel, izinto ezichasene ne-asidi, i-oyile yokuthintela umhlwa, njl., kumphezulu weemveliso zentsimbi.
2. Umaleko okhuselayo wesinyithi: Umaleko wesinyithi okanye i-alloy engarulisiyo, njenge-zinc, i-tin, i-nickel, i-chromium, ubhedu, i-titanium, njl., igqunywe kumphezulu weemveliso zentsimbi. Iindlela eziqhelekileyo ziquka i-electroplating, i-spray plating, i-hot dip plating, njl., kodwa umaleko okhuselayo wesinyithi osetyenziswa kwiimveliso zentsimbi kufuneka ngokubanzi ube yi-galvanized eshushu. Ngenxa degreasing yobuchwephesha kunye nokususwa umhlwa ye workpiece epleyitiweyo phambi plating, kunye nobushushu obuphezulu ukuntywiliselwa plating kwi zinc anyibilike 440 degrees Celsius, ukutyabeka kunokugquma iziphene ezininzi kunye nezikhewu, ukuphepha ukurusa kwixesha elizayo (ingakumbi ilungele umhlwa. ukuthintela iimveliso zentsimbi zangaphandle), kwaye ube nokusebenza kakuhle kokuncamathela.
3. Uluhlu olukhuselayo lweMichiza: Uluhlu olukhuselayo olwenziwe ngamachiza kunye neendlela ze-electrochemical ukwenza ifilimu engeyiyo-metallic phezu kweemveliso zetsimbi, ezifana nobumnyama, i-blueing, unyango lwe-phosphate, njl.
Uluhlu olukhuselayo olufunyenwe ngokusebenzisa ezi ndlela zingentla zineempembelelo zokukhusela kunye nokuhlobisa. Kodwa kwiimveliso zentsimbi, uninzi lwabasebenzisi baya bebafuna ngamandla ukuba umphezulu weemveliso zentsimbi unganyangeki umhlwa kuphela, kodwa ube nokwakheka okwahlukeneyo, iziphumo ezinomacala amathathu, okanye iziphumo zobugcisa ezinje ngediliya okanye zakudala, okanye inkangeleko entle. Ngoko ke, ngesiseko soku ngasentla, kubaluleke kakhulu ukukhetha uphawu lwepeyinti kunye nobudlelwane obunamandla kunye nokuchasana nokuguga kwi-substrate evela kumawaka eentlobo zepeyinti ezithengiswa kwiimarike, kunye nendlela yokusetyenziswa efanelekileyo. Ukhetho olujoliswe kuyo kuphela lunokufezekisa umphumo ofunekayo wokuhlobisa kunye nokunciphisa umsebenzi wokulondoloza emva kweminyaka emininzi.
