TH854B - Halogenate method - Google Patents

Abstract

The periodic process of halogenate, polymer material or solid metal consists of the following steps: (a) organize a closed system consisting of a tank inside with air at atmospheric pressure and with inlet and outlet, Heat exchanger And the circulating pump, all of them connected in series. (B) loaded polymer or solid metal material in this tank; (c) heated the tank and this material at the selected temperature range of approximately 37.78 ° C ( 100 degrees F) to approximately 93.33 degrees C (200 degrees F) by passing air into the heat exchanger (d) sucking air out of this system (e) adding halogen to this system in an amount (i). Exceeding the amount of halogenated polymer material halogenate required. To the desired step up to approximately 10 percent and (ii) sufficient to induce digestive pressure (partialpressure) in the system in the range of approximately 0.007 kg / sq. cm (0.1 psia) to approx. 0.21 kg / sq. cm.% (3 psia) (f) Add sufficient quantities of inert gas to the system to This causes the total pressure in the system to be approximately one atmosphere (g), maintains the temperature at the selected level by circulating the halogens / inert gas through the heat exchanger (h), making the halogens / inert mixed gas. It flows several times enough to reduce the amount of halogen to less than approximately 5 percent of the amount of halogen initially added to this system (i) extracting all the gas from the system (j). The system yields an approximation of atmospheric pressure and (k) ejects the material from the system:

Or solid metal, which consists of the following steps: (a) organize a closed system consisting of a tank with air inside at atmospheric pressure and with inlet and outlet, heat exchanger. (B) this tank is loaded with polymer or solid metal material (c) heated the tank and this material at the selected temperature range of approximately 37.78 ° C ( 100 degrees F) to approximately 93.33 degrees C (200 degrees F) by passing air into the heat exchanger (d) sucking air out of this system (e) adding halogen to this system in an amount (i). Exceeding the amount of halogenated polymer material halogenate required. To the desired stage to approximately 10 percent and (ii) sufficient to produce a partial pressure in the system in the range of approximately 0.007 kg / cm2 (0.1 psia) to approximately 0.21 kg / m2. R.S. % (3 psia) (f) Add sufficient amount of inert gas to the system to bring the total pressure in the system to approximately one atmosphere (g), maintaining the temperature at the selected level by swirling the halogens / inert gas mixture.
