Abstract
The present invention relates to adsorbing material. Technologically, the present invention features that the adsorbent comprising sodium sulfate, potassium sulfate, ammonium chloride, calcium oxide, salt, potassium chloride and one or several kinds of granular material, which is insoluble in mosquito repellant and non-reactive with mosquito repellant and has smelting point higher than 100 deg.c and homogeneous size is filled into a pipe and that the two ends of the pipe are sealed with adhesive silicate in the amount of no effect on the adsorbent. So, the core rod for electrothermal liquid mosquito repelling unit has complex structure comprising casing and adsorbing core, and altering the wall thickness of the casing can change the cross section area of the adsorbing core. The present invention is used in electrothermal liquid mosquito repelling unit.
Description
The present invention relates to a kind of sorbing material.
Core rod for liquid electrothermal mosquito dispeller (hereinafter to be referred as plug) is generally made with cellular graphite, pottery etc.(referring to volumes such as " newly organized home electrical heater complete works " Wang Wenchao, 459P, three, liquid electrothermal mosquito dispeller joint).In recent years, plastics plug such as ultra-high molecular weight polyethylene sintering plug abroad appear.(relevant technologies is seen this Gong of Ri Open special permission 1996,216264 designations " super high molecular weight Port リ エ チ レ ン System Duo Kong Quality Ti System making method " flat 7-52263 of Ji Te Open " プ ヲ ス チ ツ ク System Duo Kong Quality cylindrical body manufacturing process ".Classification B29K105/04).The plug shape is generally diameter 7～7.15mm, the cylinder of high 72～73mm.Effect is the absorption culicifuge and is volatilized.Principle is that an end inserts in the culicifuge in the soup bottle down, and the other end is inserted in the electrothermal ring up, culicifuge because of the siphonage of plug micropore by under rise to an end up, be subjected to electrothermal ring heating vaporization, the volatilization mosquito repellent.Characteristics are that an end contacts with organic solvent more than 80 ℃ up.Basic instructions for use: one, a kind of rate of volatilization of plug (unit interval volatile quantity) is certain; Two, rate of volatilization meets instructions for use.But existing plug can't satisfy, and reason is to have two hang-ups: one, stop up.Graphite, ceramic-like plug be because of micropore rate of closed hole height, and solute in the culicifuge is in case meet that closed pore stops up and after the retardance at an end up, can overheated carbonization, and aggravation is stopped up, and causes more solute carbonizations, forms vicious circle, and rate of volatilization descends until being zero thereupon.The plastics plug then contacts swelling because of an end up with organic solvent more than 80 ℃, and (see " plastics performance application manual " revised edition, Qian Zhi exert oneself compile 498P) destroyed microcellular structure, rate of volatilization is plunged to zero; Two, rate of volatilization only depends on material character such as microcellular structure rather than processing method, and the mandrel material kind is very few, so also can't not satisfy instructions for use even do not consider blocking factor.
The purpose of this invention is to provide a kind of core rod for liquid electrothermal mosquito dispeller that stops up also available processing method setting rate of volatilization that do not have.
The present invention mainly adopts sodium sulphate Na
2SO
4, potassium sulphate K
2SO
4, ammonium chloride NH
4Cl, calcium chloride CaCI
2, salt, potassium chloride (KCl) and comprising be insoluble to culicifuge, not with culicifuge generation chemical reaction, molten point＞100 ℃, particle diameter evenly, shape of particle can make a kind of or several mixtures in the bulk material in the space that formations is enough big between particle pour in the pipe as vapor, and make each long 1-5mm section of vapor two ends include the silicates of the amount that does not influence the vapor function and comprise that above-mentioned vapor is had a kind of or several mixtures in the material of cementation so that the vapor two ends bond seals.Have shell and inhale the two-part composite construction core rod for liquid electrothermal mosquito dispeller of core so just constitute.Above-mentioned vapor is regularly arranged in pipe with uniform particle diameter, natural geometry in particular because of particle produces hole between particle again, thereby make vapor form the microcellular structure of full open aperture. produce extremely strong siphonage, be insoluble to physicochemical properties such as culicifuge again because of it, make micropore not blocked.Stop up thereby obtained the incomparable nothing of existing sintering class plug, do not have the excellent effect of volatilization decay.
Another novel technical characterictic of the present invention is that cross-sectional area and the directly proportional relation of rate of volatilization according to plug is inhaled core make the plug external diameter certain, change the cross-sectional area of shell wall thickness with corresponding change suction core, just reach the purpose that changes rate of volatilization.Just available processing method is set the rate of volatilization of plug.
Did following experiment to adopting plug of the present invention.
Condition: Chinese and Western Pharma Inc. utensil one cover (120 ℃ of heating-up temperatures) (to call the A utensil in the following text) and 40ml culicifuge, Zhuan Chen company utensil one cover (126 ℃ of heating-up temperatures) (to call the B utensil in the following text) and 48ml culicifuge; Two of the utility model plugs, external diameter is 7mm, long 72mm, wherein a shell wall thickness 1.5mm inhales core diameter 4mm (to call the A rod in the following text).Another shell wall thickness 2.2mm inhales core diameter 2.6mm (to call the B rod in the following text); 25 ℃ of environmental temperatures (on average).
Process: A, B rod are inserted respectively in the culicifuge of A, B utensil, top, plug upper end is seen wetly after 6 minutes, begins heating, begins volatilization after 3 minutes.
The result: A utensil culicifuge in September 25 12:00 be 40ml, 23:00 was 0ml to October 8, rate of volatilization is 0.125ml/h, meet in section celebrate magnificent company standard; B utensil culicifuge in September 25 12:00 be 48ml, 18:00 was 0ml to October 25, rate of volatilization is 0.08ml/h, meets village minister company standard.Overall process does not have the decay of obstruction.To test the back plug and inhale core pulverizing chemical examination, the result proves that no solute is residual.
Embodiment: pour into external diameter 7mm respectively after sodium sulphate and potassium chloride mixed with 60: 40 weight ratios, wall thickness 1.5mm and external diameter 7mm compress in the earthen-ware pipe of wall thickness 2.2mm, expose the 1-2mm recess, are pressed into the 0.5g talcum powder, and vibration is infiltrated, and the baking knot is finished.Experimental result is seen above-mentioned.
