APAKAH MAKSUD VULCANIZATION dalam CORSICA?
Pemvulkanan
Vulkanisasi adalah proses kimia untuk menukarkan getah asli atau polimer yang berkaitan ke dalam bahan yang lebih tahan lama melalui penambahan sulfur atau kuratif atau akseleratorik yang setara. Aditif ini mengubah suai polimer dengan membentuk silang silang antara rantai polimer individu. Bahan-bahan vulcanized kurang lengket dan mempunyai ciri-ciri mekanikal yang unggul. Walaupun pengawetan getah telah dilakukan sejak zaman prasejarah, proses pemvulkanan moden, yang dinamakan sempena Vulcan, tuhan api Rom, tidak dikembangkan hingga abad ke-19. Hari ini, pelbagai produk dibuat dengan getah tervulkan, termasuk tayar, sol kasut, hos, dan tali pinggang penghantar. Getah tervulkan keras kadang-kadang dijual di bawah nama-nama jenama ebonite atau vulcanite, dan digunakan untuk membuat artikel seperti kepingan klarinet dan saxophone, bola bowling dan poket hoki.
Definisi vulcanization dalam kamus Corsica
Takrif pengguguran dalam kamus adalah proses merawat dengan sebatian sulfur atau sulfur di bawah haba dan tekanan untuk meningkatkan keanjalan dan kekuatan atau menghasilkan bahan keras seperti vulcanit. Takrifan lain dari vulcanization adalah proses merawat dengan proses yang sama dengan pemvulkanan getah untuk memperbaiki sifat-sifat bahan.
