The cement mea hoʻohāhā is the core material in foam concrete. The only good cement foaming agent can make high-performance foam concrete products. Today I will share with you how to make a cement foaming agent. Mainly introduce five kinds of cement foaming agents, they are magnesium oxychloride cement foaming agent, rosin soap cement foaming agent, mea hoʻohāhā ʻōhua huamoa, concrete composite foaming agent, engineering cement foaming agent.
1. ʻO ka mea hoʻoheheʻe ʻia ʻo Rosin soap ciment: start to mix rosin and caustic soda, mix and heat; a laila hoʻoheheʻe SM superplasticizer, ʻakika citric a me ka pauka silika i ka wai, put the above two mixtures by heating and heat preservation Mix in a heating container, hoʻohui i ka wai a hui like, and mix the required amount of powder into the above-mentioned secondary mixture. Hoʻohālikelike ʻia me nā mākau e kū nei, the method of composite foaming has been used to greatly improve the quality of commodity foams. The inner wall of the bubbles formed by foaming can also form a very thin polymer crystal film with waterproof function, participate in the cement foaming agent The mortar also has a good thermal insulation function.
2 the concrete composite foaming agent: contains the following processes: 1. E hana i ka mea hoʻoheheʻe wai kūpono; 2. Make a fixed amount of foaming agent; 3. Make some compound foaming agent; 4. Write foam through foaming to the foam The concrete mixture is mixed and then cast into shape. After adding the waterproof concrete composite foaming agent prepared by the above method, the foam concrete can overcome the shortcomings of its large water absorption rate, so that the waterproof thermal insulation and thermal insulation functions are improved.
3 mea hoʻohāhā ʻōhua huamoa: made by the following methods: firstly mix cement, pauda keramika, wai, etc. e like me kekahi ratio nuipaʻa, hui like a hoʻomākaukau i ka slurry sima. The egg yolk, mea hoʻopaʻa, dispersant, mea mālama, and water are mixed according to a certain mass ratio to form a uniform and fine closed-cell foam. Take a certain volume of the foam to join the cement concrete slurry, e hui like, and then cast it into a mold for maintenance. The cement foaming agent has easily obtained materials and simple foaming technology and overcomes the disadvantages of poor stability of traditional surfactants, lack of animal and plant protein-based cement foaming agents, and high cost.
4. ʻO ka mea hoʻoheheʻe ʻana o ka magnesium oxychloride: firstly mix the appropriate bone glue and urea-formaldehyde resin and participate in 10 times of water. After the temperature reaches 75 degere, heat and smelt for about half an hour to form a glue solution, and then dodecyl benzenesulfonate Sodium, triethanolamine, etc. huikau. After the temperature reaches 75 degere, it is heated for about 5-10 minuke, and finally diluted with water to make a product. Nā hiʻohiʻona: The quality of the goods is good, the cost is low, a maʻalahi loa ke ʻano.
5. ʻO ka mea hoʻoheheʻe sima no ka ʻenekinia: Common are linear alkyl sulfate, foam stabilizer alkyl alcohol amide, fatty alcohol polyoxyethylene ether sodium sulfate, kōkua calcium chloride, a pela aku. ʻO ka ʻenehana hana e like me kēia: the ingredients are mixed and mixed evenly at room temperature. The invention can announce a white bubble with very high foaming power, kūpaʻa maikaʻi loa, and can be widely applied to the production of foamed concrete, foamed lightweight brick and bubble mixed lightweight soil, and is also suitable for earth pressure balanced shield Soil improvement in structural construction.
