The present invention provide a water content measurement method for a hydrogen fluoride-containing compound represented by the general formula: XF路nHF (where X is either one of K, NH4, Na and Li; and n is a rational number greater than 0), including the steps of causing thermal ...
It has been shown that people of all ages can benefit from the topical and systemic effects of water fluoridation. However, the increase in consumption of bottled water, either to substitute for or supplement consumption of water from public sources, has implications for safe fluoride supplementation...
5. Apply in water sources, aquarium, hydroponics, spas, swimming pools and other water systems. 6. Electrode probe can be replaced - Replaceable BNC pH sensor probe. Product Specification Instrument Level: Grade 0.01 PH Measuring range:
The invention relates to a terpolymer of tetrafluoroethylene (TFE) monomer, polyvinylidene fluoride (PVDF) monomer and hexafluoropropylene (HFP) monomer for forming an ultrafiltration or microfiltration membrane, method of forming said m... Muller, Heinz-joachim,D Mullette 被引量: 17发表: 2004年 ...

Due to higher flexibility and lower mass with sufficient thermal resistance, polyvinylidene fluoride fibers with a diameter of 0.15 mm are preferred to metallic fibers with even lower diameter. The fiber is coated with a thermosensitive layer (Figure 8(a)) consisting of a polymer paste with 2% ...
it is necessary to conduct extensive research to determine if there are any potential side effects on the human body if graphene or silver particles are accidentally released from the sensor structure and inhaled by the subject. Mahbub et al. suggested a patch of Polyvinylidene-Fluoride film (piez...
[21] used a water-pressure sensor to measure static stress in the tire–ground contact area. Cheli [22] used a thin polyvinylidene fluoride (PVDF) piezoelectric film as a sensor to dynamically measure contact stress, and many other scholars used the pressure plate method to study contact ...
(Fat, Oil and Grease) in waste water released from both domestic and industrial premises. NMR is also used to measure fluorine during industrial processes, e.g. aluminium smelting, in order to maximise yield whilst also minimising the emission of toxic fluoride gases. More generally, NMR ...
Instrument for measuring humidity in climatic chambers The considered miniature adsorption humidity sensor on barium fluoride basis has been developed for a study of humidity structures in cases in which requir... 被引量: 0发表: 1987年 A LOOP CURRENT DRIVING MEASURING INSTRUMENT OF TEMPRATURE AND ...
