Basebeletsi ba lihlahisoa tsa zinc alloy ba tlameha ho tseba le ho utloisisa litšobotsi tsa lisebelisoa tsena, 'me tlhahlobo le tlhaloso ea litšobotsi tsa alloy ea zinc li sebelisoa hangata.
1. Overview of Zinc Alloy
Zinc alloy e thata ebile e matla, 'me ke sebaka se loketseng bakeng sa machining, ho bopa, khatiso,
tlhahiso le lisebelisoa tsa ho kopanya. Tafole e bonts'a thepa ea li-alloys tsa zinki.
Sehlahisoa se seng le se seng sa zinc alloy se na le litšobotsi tsa sona tse ikhethang, kahoo khetha sehlahisoa se molemo ka ho fetisisa
e lumellana le litlhoko tsa hau.
Litšobotsi tsa alloy ea zinc:
● thata ebile e tiile
● High conductivity
● Ho fetisa mocheso o phahameng
● Thepa e entsoeng ka theko e tlaase
●Maemo a mararo a nepahetseng le a tsitsitseng
● Ts'ebetso e ntle ea lebota le tšesaane
● Ts'ebetso e ntle ea ho pholisa, ho bonolo ho hokela
●Sehlahisoa se felileng sa boleng bo holimo
● Anti-corrosion e matla haholo
● E sebelisana hantle le tikoloho, e ka sebelisoa hape
Index ea litšupiso: 1=index e phahameng ka ho fetisisa, 5=index ea tlaase-tlaase
Ho hanyetsa ho arohana ha mocheso o phahameng.
Bokhoni ba motsoako oa ho hanyetsa khatello e hlahisoang ke liphetoho tsa mocheso, ho atolosoa ha mocheso
le ho honyela.
B e hanyetsana le ho robeha ha serame le deformation.
Bokhoni ba li-alloys ho hanela deformation, fracture, le ho kobeha maemong a mocheso o tlase.
C machining le boleng.
Tekolo e felletseng ea ho seha, thepa ea lebili, boleng ba sehlahisoa se felileng le bophelo ba lisebelisoa.
D ts'ebetso ea electroplating le boleng.
Bokhoni ba die castings ho amohela le ho boloka plating tlasa ts'ebetso e tloaelehileng.
2. Die-cast zinki alloy
Baqapi ba karolo ea meralo ba lokela ho ela hloko thepa ea li-alloys tsa zinki
e boletsoeng ka tlase. Li-alloys tsena li hanyetsana le mongobo le ho tsosoa ho feta aluminium
lits'epe tse kopantsoeng.
