Iikhoyili zentsimbi ezifakwe umbala, ezaziwa ngokuba ziikhoyili zentsimbi ezifakwe umbala, zidlala indima ebalulekileyo kushishino lwanamhlanje nolwakhiwo. Zisebenzisa amaphepha entsimbi afakwe umbala ashushu, amaphepha entsimbi e-aluminium-zinc ashushu, amaphepha entsimbi efakwe umbala, njl.njl. njengezinto ezisetyenziswayo, zinyangwa kwangaphambili kumphezulu ngendlela ephucukileyo, kubandakanya ukucocwa kweekhemikhali kunye nokuguqulwa kweekhemikhali, kwaye emva koko zifake umaleko omnye okanye ngaphezulu weekhoyili zendalo kumphezulu. Okokugqibela, ziyabhakwa kwaye zilungiswe ukuze zenziwe. Ngenxa yokuba umphezulu ugqunywe ziikhoyili zendalo zemibala eyahlukeneyo, iikhoyili zentsimbi ezinombala zibizwa ngegama lazo, kwaye zibizwa ngokuba ziikhoyili zentsimbi ezifakwe umbala.
Imbali yoPhuhliso
Amaphepha entsimbi anombala aqala eMelika phakathi kwiminyaka yoo-1930. Ekuqaleni, ayeziingceba ezincinci zentsimbi ezipeyintwe, ezazisetyenziswa kakhulu ekwenzeni iiblinds. Ngokwandiswa kobubanzi bokusetyenziswa, kunye nophuhliso lweshishini lokugquma, ii-reagents zeekhemikhali zonyango lwangaphambi konyango kunye netekhnoloji yokuzenzekela kwemizi-mveliso, iyunithi yokuqala yokugquma ebanzi yakhiwa eMelika ngo-1955, kwaye ezo ngubo zaphuhliswa ukusuka kwipeyinti yokuqala ye-alkyd resin ukuya kwiintlobo ezinokumelana nemozulu enamandla kunye nemibala engaphelelanga. Ukususela kwiminyaka yoo-1960, le teknoloji isasazeke eYurophu naseJapan kwaye yaphuhliswa ngokukhawuleza. Imbali yophuhliso lwee-coils ezinemibala eTshayina imalunga neminyaka engama-20. Umgca wokuqala wemveliso waziswa yiWuhan Iron and Steel Corporation evela kwiDavid Company e-UK ngoNovemba 1987. Yamkela itekhnoloji ye-pretreatment chemical process-two-coating and two-baking kunye ne-roller coating chemical pretreatment, enomthamo wemveliso wonyaka oyilwe we-6.4 tons. Emva koko, izixhobo zeyunithi yokugquma imibala yeBaosteel zafakwa kwimveliso ngo-1988, zaziswa zivela eWean United eMelika, ngesantya esiphezulu senkqubo seemitha ezili-146 ngomzuzu kunye nomthamo wonyaka wemveliso oyilwe weetoni ezingama-22. Ukususela ngoko, iifektri ezinkulu zentsimbi zasekhaya kunye neefektri zabucala ziye zanikela ekwakheni imigca yemveliso egquma imibala. Ishishini leekhoyili ezigquma imibala liye laphuhla ngokukhawuleza kwaye ngoku lenze uthotho lwemizi-mveliso olupheleleyo nolupheleleyo.
Iimpawu zeMveliso
1. Ukuhombisa: Iikhoyili ezinemibala zinemibala etyebileyo neyahlukeneyo, enokuhlangabezana nokufuna ubuhle kumashishini ahlukeneyo. Nokuba zintsha kwaye zintle okanye zikhanya kwaye zinomtsalane, zinokufumaneka ngokulula, zongeza ubuhle obukhethekileyo kwiimveliso nakwizakhiwo.
