The ingredients contained in the medical stone (according to the analysis of Dr. Yi Fushou, Pharmacy):
(1) ferrous oxide 1.29%; (2) iron oxide 1.40%; (3) anhydrous phosphorus (phosphoric anhydride) 0.26%; (4) manganese oxide 0.02%; (5) magnesium 3.55%; (6) potassium 3.19 %; (7) adsorbed water 1.10%; (8) calcium oxide 2.00%; (9) sodium 3.16%; (10) titanium 0.30%; (11) combined water 0.90% (+). Moreover, the medical stone does not contain radioactivity. (The Department of Radiology of the University of Pharmaceutical Sciences.)
Arsenic containing heavy metals on the problem, according to Japanese Pharmacopoeia prescriptions former state test subject purity natural aluminum silicate, which according to Japanese Pharmacopoeia eighth prescription pharmacy arsenic test method, GUTZIT test method, the result is: heavy metal 40 ppm or less and arsenic 4 ppm or less are all below the allowable value.
It can of course be said that the composition of the medical stone is non-toxic and is acceptable as an internal medicine.
Gasketed plate heat exchangers, also known as gasketed plate-and-frame heat exchangers (GPHEs), provide efficient heat transfer in compact equipment with a small footprint - much smaller and more efficient than shell-and-tube heat exchangers.
Plate heat exchangers are designed to optimize heat transfer, because the corrugated plates provide by far the greatest surface area through which the heat can be drawn from one gas or liquid to the Other.
The units also have a flexible design and are easy to service and maintain.
Gasketed plate heat exchangers benefits:
Precision heat transfer - closer approach temperature, true counter current flow, 80-90% less hold-up volume
Low overall cost - low capital investment, reduced installation costs, limited maintenance and operating costs
Maximum reliability - less fouling, stress, wear and corrosion
Environmentally responsible - minimum energy consumption for maximum process effect, reduced cleaning
Easy to expand capacity - simply add or remove plates on the existing frame
The product range is extremely wide and is used in duties for heating, cooling, heat recovery, evaporation and condensation in industries ranging from HVAC, refrigeration, engine cooling, dairy and food to heavier processes like chemical processing, oil production and power generation.
Gasketed plate heat exchangers may be the industry standard for general heating and cooling duties, but the technology inside a GPHE is far from standard. All plate heat exchangers are NOT created equal, and we've seen the consequences of choosing heat exchangers purely based on cost. We understand cost is important, but in most circumstances the costs to repair or replace units, as well as the inefficiencies of undersized units, far outweigh the upfront capital cost savings.
Types of gasketed plate heat exchangers
Industrial - an extremely versatile range of heat exchangers for use in all types of industries
AlfaQ AHRI certified - similar to Industrial GPHEs, but are AHRI certified for HVAC applications
Industrial semi-welded - used in refrigeration when gaskets are not suitable for one of the media and when higher design pressures are needed
WideGap - used for applications involving fibrous liquids, highly viscous fluids, and fluids containing coarse particles
AlfaVap evaporators - tailor-made, rising film plate surface evaporator
AlfaCond condensers - a compact, plate surface vacuum condenser
Diabon - graphite Heat Exchanger used for tough corrosive media
