Erish nuqtasi nima?
Erish nuqtasi - bu standart atmosfera bosimida moddaning qattiq holatdan suyuqlikka o'tish harorati. Moddaning erish nuqtasiga qizdirilganda, tartibli qattiq strukturadan tartibsiz suyuqlik strukturasiga o'zgaradi. Erish nuqtasi qat'iy belgilangan haroratdir, Odatda sof moddalar uchun o'ziga xos qiymat. Biroq, murakkab aralashmalar yoki qotishmalar uchun, alyuminiy qotishmalari kabi, bir qator erish nuqtalari bo'lishi mumkin.
Alyuminiyning erish nuqtasi nima?
Alyuminiyning erish nuqtasi nima? Alyuminiyning erish nuqtasi qattiq alyuminiy etarlicha yuqori haroratgacha qizdirilganda qattiqdan suyuqlikka o'tishni boshlaydigan haroratni anglatadi.. Alyuminiyning erish nuqtasida, alyuminiyning tuzilishi mahkam o'ralgan panjaradan erkin harakatlanuvchi suyuqlikka o'zgaradi. Alyuminiyning erish nuqtasi moddaning xususiyatlarining muhim ko'rsatkichi bo'lib, alyuminiy materiallarini qayta ishlash va ishlatish uchun juda muhimdir.

Alyuminiyni eritish qiyin?
Alyuminiy qotishmasining erish nuqtasi ma'lumotlar jadvalidan, alyuminiy uchun erish nuqtasi boshqa oddiy metallar bilan solishtirganda nisbatan past erish nuqtasiga ega ekanligini bilish mumkin. Shuning uchun, sof jismoniy xususiyatlar nuqtai nazaridan, alyuminiy nisbatan oson eritiladi.
Biroq, alyuminiy isitish vaqtida oksidli qatlam hosil qilishi mumkin, va alyuminiy oksidi erish nuqtasi mavjudligi alyuminiyning erish nuqtasini oshiradi, erishini qiyinlashtiradi. Shuning uchun, alyuminiyni eritish jarayonida, odatda oksid qatlamini yo'q qilish yoki kamaytirish uchun choralar ko'rish kerak, himoya gaz yoki erituvchi vositadan foydalanish kabi.
