<\/p>\n

I. Struktur kelalang vakum<\/h2>\n

Kelalang vakum biasanya terdiri daripada tiga bahagian: cawan dalam, cawan luar dan penutup. Cawan dalam bertanggungjawab untuk menyimpan cecair dan biasanya diperbuat daripada keluli tahan karat atau kaca, yang mempunyai prestasi penebat yang sangat baik dan ketahanan. Cawan luar digunakan untuk melindungi cawan dalam dan mengasingkannya daripada persekitaran luaran, dan biasanya diperbuat daripada plastik atau logam. Tudung digunakan untuk mengelak cawan dalam dan biasanya diperbuat daripada bahan plastik atau silikon.<\/p>\n

II. Prinsip kelalang vakum<\/h2>\n

Prestasi penebat kelalang vakum adalah berdasarkan dua prinsip: pengaliran haba dan kehilangan haba sinaran.<\/p>\n

1. Pengaliran terma<\/h3>\n

Pengaliran terma ialah pemindahan haba melalui pergerakan dalaman molekul. Dalam kelalang vakum, lapisan vakum terbentuk di antara cawan dalam dan luar, dan tiada molekul di udara yang boleh mengalirkan haba, dengan itu mengurangkan pengaliran haba. Di samping itu, cawan dalam biasanya diperbuat daripada bahan dengan kekonduksian terma yang tinggi, yang boleh menyerap dan membebaskan haba dengan cepat, dengan itu mengurangkan pemindahan haba di dalamnya.<\/p>\n

2. Kehilangan haba sinaran<\/h3>\n

Kehilangan haba sinaran merujuk kepada proses di mana objek menghantar haba ke persekitaran sekeliling melalui sinaran. Dalam kelalang vakum, dinding dalam cawan luar biasanya diperbuat daripada bahan bersalut perak atau tembaga, yang boleh memantulkan haba sinaran dan mengurangkan kehilangan haba.<\/p>\n

Menggabungkan dua prinsip di atas, kelalang vakum boleh mengurangkan kehilangan haba dengan berkesan dan mencapai penebat jangka panjang.<\/p>","protected":false},"excerpt":{"rendered":"
