千萬不要用微波爐燒開水!

用微波爐燒開水或牛奶會爆炸嗎?

實驗者把一隻燒杯盛滿水用微波爐加熱,然後取出,用勺子舀了一勺咖啡粉,將咖啡粉連勺子一起放入水中,結果水馬上從燒杯裡噴濺出來,濺到實驗員戴著防護手套的手上。上傳這段視頻的網友提醒人們:“千萬不要用微波爐燒開水!”

因為微波爐是用來加熱食物的說法是不太恰當的,因為微波爐是利用micro-waves讓水分子產生共振,與傳統的加熱相差太大。

用瓦斯爐燒開水是利用水溫上升,讓水分子的平均動能隨著時間而擴大,動能的增加來自於水分子間彼此的碰撞所致,對著整群水分子加速,屬於緩慢碰撞,產生明顯的對流,也因此最後才有沸騰的現象。

用微波爐燒開水的過程是利用微波的能量破壞水分子間的氫鍵,但是由於氫原子與氧氣原子彼此對於電子親和力的不同,水分子之間的氫原子與氧原子又產生鍵結的現象,隨著氫鍵的破壞與重組,使得水分子不斷地在擾動,水分子重新排列的結果,放出紅外線,使得個別水分子的平均動能增加,由於是個別的現象,因此外觀上看不出有明顯的沸騰的現象。但如果外界擾動整杯水,水分子與水分子間產生碰撞,將釋放出巨大的能量,進而產生突沸之現象,不可不小心以免造成不必要的傷害。

採用特殊的三度運動空間完美均勻混合粉劑、固體、液體、或懸浮液,Inversina提供的混合比任何攪拌機還急劇進而降低混合時間。Inversina已用於各種應用,如藥物配製、粉末冶金、高性能材料、植物組織、生物科技、化學、食品、醫學、質量保證、樣品製備。

它有手動或自動模式,尺寸範圍從實驗室到生產規模種類繁多的配件,以適應各種混合過程。

The Inversina perfectly homogenizes powders, solids, liquids, or suspensions. Using special three-dimension inversion kinematics, the Inversina offers much gentler mixing and more reproducible results than any other blender at drastically reduced mixing times. The Inversina has been used in a variety of applications, such as pharmaceutical compounding, powder metallurgy, performance materials, implants and biomaterials, chemical, food, alternative medicine, and quality assurance / sample preparation. It comes in both manual or automatic models, with sizes ranging from laboratory to production scale and a large variety of accessories to fit every mixing process.

Powder Homogenizing

Our Tumbler Mixers use inversion kinematics for mixing solids and liquids.  This allows intensive, fast and very gentle mixing without segregation.  The astonishing three-dimensional motion (Paul Schatz principle) combines a figure-of-eight movement with rotation and sets the substances in a rhythmic, pulsating motion.  This technique is much more reliable than the techniques used for barrel mixers, v-blenders, double cone blenders or ribbon mixers, which have segregation zones and longer mixing and cleaning times.

Manual Mini-Inversina
