Description

Sulfur magnesium citrate material and application thereof
One. technical field: the invention belongs to the FRIM class, relate to the material that use in industry, agricultural, building, building materials, field such as civilian, particularly a kind of novel material sulfur magnesium citrate material.
Two. technical background: invented magnesia oxychloride cement (or claiming magnesium cement) afterwards since Frenchman's Sorel in 1867, the scientist who participates in the world this cement is studied gets more and more.People strengthened magnesium cement product with glass fibre again and got inorganic composite materials afterwards, and had produced FRIM.Since this product came out, countries in the world were to its history in existing more than 100 year of research and development, and its product is also varied, can be widely used in industry, agricultural, building materials, multiple field such as civilian.In China over nearly more than 20 years, the FRIM development rapidly, the unorganic glass steel mill various places, town and country that also spread all over the country.
Although over more than 100 year, Chinese and foreign department the scholar constantly research and develop magnesia oxychloride cement, and make encouraging progress.But its fatal shortcoming seriously hampers exploitation, the utilization of people to it again.The inherent defect of magnesia oxychloride cement has:
(1) thermal expansivity is strong, deformability is big, easy to crack
Magnesium cement is in solidification process, its volume expands, mainly be because the curing of magnesium cement is an exothermic process, generally temperature just reaches 100 ℃ in several hours or tens hours, even up to 160 ℃, in violent like this exothermic process, magnesium cement produces thermal expansion and causes the product distortion, causes warpage and cracking owing to distortion has produced stress.The swelling property of magnesium cement is even more serious in wet environment, is 10 times in the natural curing.
(2) water resisting property is poor
The water resisting property difference major cause of magnesium cement is that the crystallization point of contact of chlorine oxygen magnesium aquation phase has very high solubleness, particularly under fluviation, and the Cl of aquation phase -In the ease water inlet, chlorine oxygen magnesium aquation is disintegrated mutually, thereby causes intensity to reduce.In order to improve the water resisting property of magnesium cement, people have adopted and have added various types of additives.But up to the present,, use additive also can only partly relax the magnesium cement amplitude that intensity reduces under wet environment for the water resisting property problem of magnesium cement.But the length of time of cement is still very short, lacks permanent stability.
(3) get damp, return halogen, scum
The major cause of getting damp, return halogen, scum of magnesium cement also is that the magnesium chloride in the magnesium cement causes.The exsiccant magnesium chloride is placed in the air, and magnesium chloride will absorb moisture content and deliquescence soon, and sal epsom can hydrolysis in air, improves the water resisting property and the moistureproofness of magnesium cement, so also there is human sal epsom to make blender abroad, perhaps both mix use.But after sal epsom surpassed 3%, the magnesium solidified cement body was prone to shrinkage crack, and intensity also can reduce.Because the crack problem of magnesium cement causes the consumption of sal epsom in cement to reduce gradually behind the interpolation sal epsom, does not just re-use finally.The scum problem of magnesium cement product also is a defective of magnesium cement, influences outward appearance and quality product.People often manage to reduce the consumption of magnesium chloride brine as far as possible in actual production, get damp, return the possibility of halogen, scum with minimizing, but can influence the intensity of product simultaneously again because of the minimizing of magnesium chloride consumption.The product that every water resisting property is good returns the halogen problem and has also just solved.
(4) be corrosive, particularly not before the completely solidified, the chlorion (Cl in the bittern -) reinforcing bar there is very big corrosive nature;
At present, various countries mainly show as the research of magnesia oxychloride cement: (1) develops various additives; (2) select multiple stopping composition for use; (3) change mechanical means; (4) change technical process.Although people develop the performance that various additives and mechanical means improve magnesia oxychloride cement, all produce little effect.For example, select for use phosphoric acid or phosphoric acid salt to do additive, water repelling property is improved, but products solidifying is slow, is to open mould in 120 hours by opening moding in 24 hours.Cause the place to increase, mould increases, and the production time is elongated.Select for use vitriol to do additive, as ferrous sulfate, water resistance is improved, but curing is too fast, and product has oyster white to become the duck's egg green, and the economic worth of product is descended, and does not satisfy people to the lily requirement of product.Add urea-formaldehyde resin as waterproof additive, product is subjected to weather effect serious, causes intensity to reduce, and water repelling property is poor.Development additive, change equipment, flow process all can not fundamentally solve the intrinsic problem of magnesia oxychloride cement, and reason is that the reaction system of magnesia oxychloride cement does not change.
