1. Isixazululo sokushintsha umbalatape yethusi
(1) Lawula ukugcwala kwesisombululo se-asidi ngesikhathi sokukhetha.Endabeni yokugeza ungqimba lwe-oxide ebusweni bomugqa wethusi ohlanganisiwe, ukugxila kwe-asidi ephezulu akwenzi mqondo.Ngokuphambene nalokho, uma ukugxilisa ingqondo kuphezulu kakhulu, i-asidi esele enamathele ebusweni bomucu wethusi akulula ukuwasha, futhi ukungcoliswa kwamanzi okuhlanza kuyashesha, okuholela ekugxilweni okuphezulu ngokweqile kwe-asidi esele emanzini okuhlanza, okwenza umugqa wethusi emva kokuhlanza uthambekele ekushintsheni umbala.Ngakho-ke, lapho kunqunywa ukugxila kwesisombululo se-pickling, izimiso ezilandelayo kufanele zilandelwe: ngesisekelo sokuthi ungqimba lwe-oxide ebusweni bomugqa wethusi lungahlanzwa, ukugxila kufanele kuncishiswe ngangokunokwenzeka.
(2) Lawula ukuhamba kwamanzi ahlanzekile.Lawula ukuqhutshwa kwamanzi ahlanzekile, okungukuthi, lawula okuqukethwe kwezinto eziyingozi njengama-ion chloride emanzini ahlanzekile.Ngokuvamile, kuphephe kakhudlwana ukulawula ukuhanjiswa okungaphansi kuka-50uS/cm.
(3) Lawula ukuhamba kwamanzi okuhlanza ashisayo kanye ne-ejenti edlulayo.Ukwanda kwe-conductivity yamanzi okuhlanza ashisayo kanye ne-passivator ngokuyinhloko kuvela ku-asidi esele elethwa ibhande lethusi eligijima.Ngakho-ke, ngaphansi kwesimo sokuqinisekisa ikhwalithi yamanzi ahlanzekile asetshenziselwa ukuhlanza, i-conductivity ilawulwa, okungukuthi, inani le-asidi elisele lilawulwa.Ngokusho kokuhlolwa okuningi, kuphephile ukulawula ukuqhutshwa kwamanzi okuhlanza ashisayo kanye ne-passivator ibe ngaphansi kuka-200uS/cm, ngokulandelana.
(4) Qiniseka ukuthi umucu wethusi womile.Ukuvalwa kwengxenye kwenziwa endaweni ephumayo yokubophela isithando somlilo, futhi okokukhipha umswakama kanye ne-air conditioner kusetshenziswa kudivayisi yokuvala yasendaweni ukuze kulawulwe umswakama nezinga lokushisa ngesikhathi sokugoqa umugqa wethusi phakathi kwebanga elithile.
(5) I-passivation usebenzisa i-ejenti edlulayo.I-ejenti edlulayo esetshenziswa efektri yethu yilena: i-benzotriazole, okuyi-BTA (ifomula yamangqamuzana: C6H5N3) njenge-ejenti edlulayo.Ukuzijwayeza kufakazele ukuthi kuyindlela elula, eyongayo futhi esebenzayo.Uma i-copper tape idlula isisombululo se-BTA, ifilimu ye-oxide ebusweni isabela ne-BTA ukuze yakhe inkimbinkimbi eqinile, evikela i-substrate yethusi.
2. Isixazululo se-copper strip shear indentation
Ukuze uvimbele ukuhlehla konqenqema lokugunda, kudingekile ngokuyinhloko ukukhetha umehluko onengqondo phakathi kobubanzi bangaphandle bommese oyindilinga kanye nendandatho yokucwenga yerabha ngokuvumelana nobukhulu nobulukhuni bomucu;ubulukhuni bendandatho yokucwecwa kwerabha buhlangabezana nezidingo zomucu ozosikwa;Uma ububanzi be-strip buncane, ubukhulu bommese oyindilinga kufanele bukhethwe ngokunengqondo futhi ububanzi bendandatho ye-rubber peeling kufanele bunyuswe.
