Kupukuta pamwamba pa machubu a galvanized square ndi njira yoyeretsera yotengera mankhwala a alkali.Chifukwa chosavuta kugwiritsa ntchito, mtengo wotsika komanso kupezeka kosavuta kwa zida, zimagwiritsidwa ntchito kwambiri.Chifukwa njira yotsuka ya alkali imadalira saponification, emulsification ndi zotsatira zina, zomwe zili pamwambazi sizingakwaniritsidwe ndi alkali imodzi.
Kawirikawiri, zinthu zosiyanasiyana zimagwiritsidwa ntchito, ndipo nthawi zina zowonjezera zowonjezera ndi zina zothandizira ziyenera kuwonjezeredwa.The alkalinity imatsimikizira kuchuluka kwa saponification reaction, ndipo alkalinity yayikulu imachepetsa kusamvana kwapakati pakati pa banga lamafuta ndi yankho, kupangitsa banga lamafuta kukhala losavuta kutulutsa.Komanso, yotsalira kuyeretsa wothandizila padziko kanasonkhezereka lalikulu chubu akhoza kuchotsedwa ndi kutsuka madzi pambuyo kutsuka zamchere.
Ndi njira yomwe imagwiritsidwa ntchito kwambiri pochotsa mafuta kuti agwiritse ntchito surfactant yokhala ndi kupsinjika pang'ono pamwamba, permeability yabwino komanso kunyowa, komanso kuthekera kolimba kwa emulsification.Kupyolera mu emulsification zotsatira za surfactant, ndi mawonekedwe nkhope chigoba ndi mphamvu zina aumbike pa mawonekedwe mafuta-madzi, amene amasintha mawonekedwe mawonekedwe ndi mtengo wa Wuxi kanasonkhezereka lalikulu chubu, kuti particles mafuta omwazika mu njira amadzimadzi kupanga. ndi emulsion.Kapena banga lamafuta lomwe silingasungunuke m'madzi pa chubu lamakabati amatha kusungunuka mu surfactant micelle kudzera pakusungunuka kwa surfactant, kuti asamutsire banga lamafuta ku njira yamadzi.
Galvanized square chubu ndi mtundu wa chubu chopepuka chachitsulo chokhala ndi mipanda chokhala ndi gawo lalikulu, chomwe chimatchedwanso chigawo chozizira.Ndi mtundu wachitsulo chachigawo chokhala ndi gawo lalikulu, chomwe chimapangidwa ndi chitsulo cha Q235 chotenthetsera kapena chozizira kapena mbale yophimbidwa ngati maziko pambuyo popindika ndikuzipanga kenako kuwotcherera kwanthawi yayitali.Kuwonjezera khoma thickening, ngodya gawo ndi m'mphepete kuwongoka kwa otentha-anagulung'undisa owonjezera wandiweyani khoma lalikulu chubu kufika kapena kuposa mlingo wa kukana welded ozizira anapanga lalikulu chubu.
Ubwino wakupindika kwenikweni ndikubwerera pang'ono, kupanga kolondola, ndi mawonekedwe olondola okha.R ya mkati mwa angle kupanga ndi yolondola kwambiri.Ubwino wopindika wopanda kanthu ndikuti utali wam'mbali ukhoza kupindika pomwe kupindika kwenikweni sikungachitike, monga kupindika molumikizana ndi kumaliza m'mphepete / m'mbali mwa machubu akulu akulu.Kupindika kwa dzenje kungathenso kupindika mbali yamkati ndi R<0.2t popanda kuphwanya khoma la chitoliro.
Kuwonongeka kwa kupindika kwenikweni ndikokhazikika/kuwonda.
Kupindika kwenikweni kumapangitsa kuti malo opindikawo atambasulidwe, ndipo mphamvu yotambasula idzafupikitsa kutalika kwa mzere wopindika;Chitsulo pa bend yolimba chidzakhala chochepa chifukwa cha kutambasula.
Cholakwika chopindika chopanda kanthu ndikuti pamene mbali yakumtunda / mbali ikupindika nthawi imodzi yopanda kanthu, chifukwa mpukutu wapamwamba ndi mpukutu wapansi umatulutsa kupanikizika palimodzi, chubu cha galvanized square chilipo, ndipo mphamvu yopanga ndiyosavuta kupitilira mfundo yofunika. , kupanga m'mbali zosakhazikika concave, lalikulu m'mimba mwake kanasonkhezereka lalikulu chubu, komanso zimakhudza ntchito khola unit ndi kupanga khalidwe.Izi ndi zinanso mbali ya dzenje mapindikidwe a kanasonkhezereka lalikulu machubu.
