Finely divided particles of II type ammonium polyphosphate (APP) which, when added to polyolefin resins, etc., afford products having a small reduction in the mechanical characteristics, a reduced particle diameter and an increased specific surface area and nevertheless, having bleed resistance and flame retardancy similar to those of conventional products, and a process for producing the particles are provided,the particles being characterized in that 80% by weight or more thereof have a particle diameter of 10 .mu.m or less and 5% aqueous solution thereof dissolved in 80.degree. C. water has 500 cps or more, and the process being a process for producing the particles by reacting ammonium phosphate with P.sub.2 O.sub.5, each in a nearly equimolar quantity, in a NH.sub.3 gas atmosphere and at an elevated temperature, comprisinga first reaction step carried out in N.sub.2 gas atmosphere without feeding NH.sub.3 gas, a second reaction step of instantaneously feeding NH.sub.3 gas or a NH.sub.3 -generating substance when hot, in 3 to 90% of the stoichiometrical quantity, and a third reaction step of slowly adding NH.sub.3 gas in a quantity or more of the remainder of the stoichiometric quantity and aging therewith, to crystallize the resulting II type APP.

For some embodiments of the present disclosure, an array substrate includes a transparent insulating substrate, a plurality of wires positioned on the transparent insulating substrate, a first insulating film positioned on the transparent insulating substrate and in between the wires, and a second insulating film positioned on the wires and on the first insulating film. By virtue of the first insulating film positioned between the wires, the wires are completely covered by the first insulating film and the second insulating film.
摘要:
In a vehicle air conditioner where air blown into a passenger compartment is heated in a heater core using cooling water for cooling a fuel cell system as a heating source, a flow amount of cooling water flowing into the heat core is controlled by a control valve based on a surplus heat quantity of the fuel cell system and a necessary heat quantity of the passenger compartment. Further, when the surplus heat quantity of the fuel cell system is smaller than the necessary heat quantity, an insufficient heat quantity is supplemented by a supplementary heater.

A duct for leading air into a vehicle compartment is divided by a partition wall into two air passages. A first air passage is capable of taking in the exterior air while a second passage is capable of taking in only the interior air. In the duct, a cooling heat-exchanger is disposed at a downstream side of a blower unit, and a heating heat-exchanger is disposed at a more downstream side of the cooling heat-exchanger. A defroster air outlet opens at a downstream side of the first air passage, a foot-side air outlet opens at a downstream side of the second air passage, and a face-side air outlet opens between the cooling heat-exchanger and the heating heat-exchanger. A face-side door for opening and closing the face-side air outlet is capable of shutting off the air inlet side of the heating heat-exchanger.
摘要:
The waste heat from a heating part mounted on a vehicle is recovered and extracted by a refrigerant for gas injection so that the heating capacity at a low ambient temperature may be effectively improved while suppressing an increase in the power consumption. At the heating time, the refrigerant is circulated in a closed circuit composed of a compressor, an indoor heat exchanger, a pressure regulator and an outdoor heat exchanger, and the refrigerant, as condensed in the indoor heat exchanger, is regulated to an intermediate pressure by a pressure regulator and introduced into a heat exchanger. In this heat exchanger, the refrigerant extracts the heat from the heating part at the side of the vehicle so that it evaporates. The refrigerant thus having evaporated is introduced through an evaporation pressure regulating valve via a gas injection passage into a gas injection port of the compressor.
摘要:
Water-insoluble ammonium polyphosphate particles are provided which include melamine-coated ammonium polyphosphate particles with the surface thereof being crosslinked by a reaction between the melamine of the melamine-coated ammonium polyphosphate particles and a crosslinking agent having a functional group capable of reacting with the active hydrogen atoms belonging to the amino group in the melamine molecule.
摘要:
An air conditioning system that can operate an air conditioner of an electric vehicle without interfering with the charging process, which utilizes a secondary battery. When operation of the vehicle is terminated and the control system determines that a frosting judgment decision is positive, the control system judges whether the charging current has dropped to a specified level or less. As soon as the charging current has dropped to or below the specified level, the excess charging current may be used for a defrosting operation. When the operation of the vehicle is stopped and the control system determines that a frosting judgment decision is negative, the control system judges whether a preliminary air conditioning switch is on. If the preliminary air conditioning switch is on, it is judged whether charging of the secondary battery is in progress. If charging is progressing, the control system determines whether the charging current has dropped to or below a specified level. As soon as the charging current has dropped to or below this specified level, preliminary air conditioning is performed to cool or warm the cabin of the vehicle during charging of the secondary battery.
