Abstract
The invention relates to a molded coal ignition exciter and the producing method. The raw material includes formaldehyde, carbamide, catalyst, liquid fuel, surface activator, plant stalk powder, curing agent and water. It includes the following steps: using formaldehyde and carbamide to make urine aldehyde resin solution, taking emulsification to urine aldehyde resin solution and kerosene under surface activator to form liliquoid, sealing to form the product. The invention has simple technology and is safe and convenient.
Description
Technical field
The present invention relates to the to ignite composition of usefulness specifically belongs to a kind of moulded coal starting mix and production method thereof.
Background technology
Using moulded coal in a large number from energy-conservation and environmental angle analysis is the preferred plan of rationally utilizing coal at present, but moulded coal point of ignition height, ash content is big, and it is very difficult to ignite, and the moulded coal that ignites needs more timber, and is time-consuming bothersome, also uneconomical.Bibliographical information is mostly made the solid matches for the black network tropine [CN86106573], oils, wax class, the ethanol that add high heating value, realize can the ignite purpose of moulded coal of a match, but the cost height is only applicable to restaurant, tourism, field work.Also utilize waste slag of alcohol, furfuraldehyde waste slag, papermaking wastewater are made starting mix, but calorific value is low, and raw material is limited, and product has the shortcomings such as peculiar smell of making us uncomfortable because of containing organism such as furfural.
Application number is that 00114273.9 Chinese patent discloses a kind of coal of igniting, its making method is formed ignition dopes with in trisulfurated phosphorus, white phosphorus, red phosphorus, the thiophosphoric anhydride one or more, and to have an igniting quick, easy to use, but form sulfurous gas in the combustion processes, acidic oxides such as Vanadium Pentoxide in FLAKES cause environmental pollution.
Application number is that 91106079.0 Chinese patent discloses a kind of shaped coal fire-leading piece, with liquefied gas residue at the peptizer aluminum napthenate, detonation suppressor diatomite exists down, obtain shell with material moulding such as hexamethylenetetramine, thin wood powders and make shaped coal fire-leading piece, this starting mix uses hexamethylenetetramine to carry out comparatively difficulty of Physical Processing moulding, and cost is higher.And form a certain amount of brine waste when in the manufacture craft process, producing aluminum napthenate, cause secondary environmental pollution.
Summary of the invention
The purpose of this invention is to provide a kind of calorific value height, easily light, ignite conveniently, safe and reliable, free from extraneous odour, free of contamination starting mix and production method thereof.
A kind of moulded coal starting mix provided by the invention, feed composition is counted by weight and is comprised: 37% formalin 18～22, urea 9～11, catalyzer 0.08～0.12, liquid fuel 50～70, tensio-active agent 0.2～0.5, plant straw powder 2～3, solidifying agent 1～2, water 5.5～6.5.
The production method of moulded coal starting mix in turn includes the following steps:
(1) formalin is added in the reactor, stir and add catalyzer down, the urea that adds total amount 1/2 earlier, under 50～60 ℃ of temperature, reacted 25～40 minutes, 2/3 the urea that adds residual content again 65～75 ℃ of reactions 40～50 minutes down, adds remaining urea again, continue reaction 10～20 minutes, make the aqueous solution of Precondensed UreaFormaldehyde Resin;
(2) solution that tensio-active agent and water are made into adds in the aqueous solution of Precondensed UreaFormaldehyde Resin, rotating speed with 1600～1800 rev/mins under the room temperature stirred 5～15 minutes, add liquid fuel and plant straw powder, stirred once more 25～35 minutes, add solidifying agent again, continue to be stirred to formation heavy-gravity liliquoid;
(3) liliquoid is packed into have the packing bag of air, sealing makes product.
Described catalyzer is a basic catalyst, can be potassium hydroxide or sodium hydroxide, or their mixture.
Described liquid fuel can be one or more in kerosene, diesel oil, gasoline and the alcohol.
Described plant straw powder can substitute with the meal that wood chip or corn cob meal, grain husk powder or orange peel are made, and granularity should be less than 60 orders.
Described tensio-active agent can be sodium alkyl benzene sulfonate or OP-10.
Described solidifying agent can be an ammonium chloride, or the mixture of sulfuric acid and ammonium chloride, or the mixture of phosphoric acid and ammonium chloride.
Moulded coal starting mix of the present invention, every gram thermal value reaches more than 10,000 kilocalories, and the Kindling sheet combustion processes of 10 grammes per square metres can reach 10 minutes, and the very hot oven phase can reach 8 minutes, and the moulded coal that can ignite fully can realize wiping the purpose that standardized branch match is conveniently lighted.Operational path is simple, and constant product quality is easy to industrialization, does not produce pollution, and product can be used for igniting of moulded coal and other combustiblesubstances, and is safe in utilization, convenient.
