In the modern chemical and steel industries, a variety of machines and equipment are often used. These devices play a very important role, and human power is not comparable. As we all know, many materials in industrial production are corrosive, if the machine is made of pure metal, then the wear will be very large, a long time can not be used, must be replaced. This is a waste of resources and is very bad for industrial Horumar {{3 {3} sidaas darteed, dadku waxay la yimaadeen habab kala duwan oo lagu kobcinayo aashitada iyo iska caabinta kuleylka ee qalabka sida qaboobaha loo qaboojiyo {{4}
Nasiib wanaagse, oo leh horumarka joogtada ah iyo horumarka tikniyoolajiyadda, dadku waxay isku daraan waxyaabo gaar ah oo la tacaali kara aluminina, oo guud ahaan walxahaasi waa wax loo yaqaan 'acids-ka', marka lagu daro hydrofluoric acid, dhammaan noocyada Maantooyinka aashitada ah wax istcimaalaan hortooda, si toos ah u nadiifiyaan carqalad weyn oo ka jirta garoonka metallalgy, bir iyo warshado kale oo culus, si ay u helaan meel weyn oo horumarka {{2}
Hadda, dib-u-habeynta tikniyoolajiyadda qaybaha alumina-ka oo si isdaba joog ah loo wanaajiyey, oo aad u badan ayaa indhaha ku haysay si ay u xalliyaan welwelkooda {{1} inay dadku ku sugayaan inay sugaan inay sugaan alumina dhoobada dhoobada ah ee ay ka fiicnaan karaan Waxqabadka ugu sareeya, dhinacyo kale ayaa sidoo kale laga heli karaa, oo lagu dabaqi karaa dhul ballaaran oo ballaaran .
