Crop straw contains a large amount of starch. Extracting the starch, not only can be used as a feed, but also can make wine, make vinegar, and sugar.
Using corn stalks to make starch first peel off the hard skin of corn stalks, cut the mites without worms into thin slices, soak them in clear water for 12 hours and then cook them in a large pot. When the hazelnuts are boiled, stir them into a paste, add appropriate amount of water to dilute and then sieve carefully. After that, the filtered slurry is placed in a fine cloth bag and squeezed or hanged to obtain wet starch.
Use bean pods to make starch to remove impurities from the sediment, and then wash off the dust with water. After that, soak it in clean water for 8-10 hours, remove it and put it into the pot for cooking. Add 10 parts of raw material per unit of soda. The proportion of kilograms is added to soda ash. When the bonfire is cooked until the pods are sticky, the pods are removed, crushed, then placed in clean water and mixed with a fine sieve. The filtered slurry is placed in a bag and squeezed to form a wet starch.
Making starch with straw or wheat straw First wash the straw or wheat straw with water, chop it and put it in a wok for cooking. Add 29 kg of boiling water and 0.12 kg of soda ash per 100 kg. After cooking for 45 minutes, remove it, put it in cold water, remove it and crush it. The finer the better. After that, the pulverized raw materials are returned to the original solution, stirred for 10-20 minutes, filtered with a fine sieve, and the filtered juice is poured into a large tank for clarification. After 12 hours, the upper layer of waste liquid with impurities is removed, and the lower layer is removed. The concentrated liquid is put into a cloth bag and squeezed to form a wet starch.
Multi-spectral grade of zinc sulfide has low absorption and scatter properties over its broad transmission range of 0.4 - 12μm. Zinc Sulfide Multispectral is a chemically vapor deposited material which is commonly used in thermal imaging. With its excellent transmission properties in the visible and infrared, Zinc Sulfide Multispectral is the material of choice for systems that have both visible and mid-wave or long-wave infrared sensors. It is slightly harder and more chemically resistant than zinc selenide.
We consistently offer various high quality optical components according to the customer's requirements use other infrared materials. Such as prisms,Spherical Lens, aspherial lens,Ball lens,Optical Windows,Achromatic Lens,cylinder lens etc.
