Zinc (Gista) Kya Hai?
Zinc aik metallic element hai jiska chemical naam Zn hai. Yeh naturally zameen ke andar paya jata hai aur duniya bhar mein use hone wali important industrial dhaaton mein se aik hai.
Zinc ko “anti-rust” metal bhi kaha jata hai, kyunke iska sab se bara kaam hota hai doosri dhaaton – khaaskar lohay – ko zang se bachana.
Zinc Ki Physical Aur Chemical Khasoosiyat
| Khasoosiyat | Tafseel |
|---|---|
| Rang | Silver ya light bluish white |
| Melting Point | 419.5°C |
| Density | Medium (7.1 g/cm³) |
| Corrosion Resistance | Bohat achhi |
| Magnetic? | Nahi |
| Reactivity | High (oxidation hoti hai hawa mein) |
Zinc halki si oxidized layer bana leta hai apni surface par, jo ise zنگ lagne se bachati hai – isi wajah se yeh protective coating ke liye bohot famous hai.
Zinc Kaisay Hasil Kiya Jata Hai?
Zinc ko zinc ore (jaise ke sphalerite) se nikal kar refine kiya jata hai. Is process mein pehlay ore ko heat aur chemical ke zariye concentrate kiya jata hai, phir smelting ya electrolysis se pure zinc hasil kiya jata hai.
Zinc ko aksar alloy form mein bhi use kiya jata hai – jaise Brass (Pital) jo copper aur zinc ka mix hota hai.
Zinc Ka Scrap Business Mein Kirdar
Zinc scrap ka business Pakistan aur duniya bhar mein grow kar raha hai. Iska sab se bara reason yeh hai ke:
- Zinc ko dobara melt kar ke asaani se reuse kiya ja sakta hai
- Yeh corrosion-resistant hai
- Bohot saare industries isay recycled form mein demand karti hain
Zinc scrap usually roofing sheets, galvanised pipes, auto parts, aur industrial machinery se milta hai.
Zinc Ka Pehchaan Kaisay Karen?
Scrap business walay log aksar zinc ko aluminium, steel, ya pital se confuse kar detay hain. Yeh rahein kuch tips:
- Rang silver ya greyish hota hai
- Magnet se chipakta nahi
- Halki se scratch karne par powder jaisa feel deta hai
- Zyada heat dene par jaldi melt hota hai (melting point kam hai)
- Awaaz sharp aur light hoti hai bajane par

Zinc Ke Aham Istemaalat
Zinc ka istemal itna widespread hai ke aap soch bhi nahi sakte ke yeh har jagah hai. Yahan kuch important use cases hain:
🛡️ 1. Galvanisation (Zنگ Se Bachao)
Sab se zyada zinc ka use hota hai steel aur iron ko galvanise karne ke liye, jisse woh zنگ se mehfooz rehtay hain. Yeh process hoti hai har tarah ke pipes, sheets, aur construction parts mein.
🧲 2. Alloys (Mix Dhaat)
Zinc ko copper ke sath mila kar Brass (Pital) banaya jata hai, jo electrical aur decorative kaamon mein use hoti hai.
🏭 3. Die Casting
Auto parts, electronics, locks aur industrial fittings ke liye zinc die casting ka use hota hai.
💊 4. Health & Nutrition
Zinc insani jism ke liye zaroori element hai. Yeh immune system, metabolism, aur wound healing mein madad karta hai. Is liye zinc vitamins tablets aur supplements mein milta hai.
🏠 5. Paints & Coatings
Zinc oxide paints aur anti-rust coatings mein use hota hai – yeh surface ko durable banata hai.
Zinc Ke Fayde – Kya Isay Nazar Andaaz Karna Ghalti Hai?
- Zنگ se bachata hai
- Recyclable hai – scrap ke liye profitable
- Lightweight hai
- Corrosion-resistant – moisture mein bhi safe
- Economical – copper ya aluminium se sasta hota hai
- Biologically Important – health ke liye bhi zaroori
