Nowadays, many places will use vacuum cleaners instead of artificial cleaning, such as shopping malls, hotels, tourist attractions, parks, airports, factories, office parks and other places. We often see workers sweep sweeping roads back and forth with the sweeper. The road to the place is clean and dusty. It can be said that this is a very practical tool car. So, how to buy a vacuum cleaner ? The automatic vacuum cleaner has obvious advantages. First, it can reduce labor costs and improve work efficiency. It only requires one worker to drive a vacuum cleaner to replace the workload of eight cleaners; the second is to improve cleaning. Strength, general road surface, the use of dust-type sweeper vehicles can clean up the garbage, sediment, dust; third is to reduce the secondary pollution of dust, dust is often lifted into the air when artificial cleaning, and produce secondary Pollution, using a sweeper to directly absorb dust, not dust does not pollute the air. There are several key elements to buy a vacuum cleaner : 1, models, the current more common hand-push, driving vacuum cleaners two, hand-type models smaller, more suitable for smaller regional use, such as hotel corridors, shopping malls, hospitals, waiting halls; The driving style is more suitable for relatively wide open areas, such as parks, factories, airports, scenic spots, and residential roads. 2, power, generally electric (charged) and fuel type. The electric type is more environmentally friendly, energy-saving and emission-reducing, suitable for most places, and will not bring exhaust pollution. 3, parameters, vacuum cleaners main parameters include the size of the work, battery capacity, continuous working time, motor power, charger specifications, body weight, brush plate diameter, roller diameter, main brush cleaning width, maximum effective cleaning area, pollution Container volume, maximum suction height, operating noise, charging time, and more. 4, after the sale, the general product free warranty for one year, maintenance for several years to lifetime. Most manufacturers can provide different types of vacuum sweeper models for comparison, users can combine the above reference factors, according to the actual use of the environment, frequency of use, price budget and service needs, choose the right brand and product.
Optical Windows are flat, plano plano that are
often used as protective barriers for electronic sensors or detectors from
outside environments. Optical Windows should be selected based on the material
transmission or mechanical properties of the substrate which according to
customer design. Optical Windows do not cause change in the magnification of a
system. Optical Windows are offered in a variety of substrates, such as
Infrared IR windows, Germanium(Ge),Silicon(Si),N-BK7,UV Fused Silica,Barium Fluoride(BaF2),Calcium
Fluoride(CaF2),Magnesium Fluoride (MgF2), B270,Zinc Selenide (ZnSe), orand Potassium
Bromide (KBr). We could provide AR
Coating for UV, IR, and NIR.
