Q:How to clean and maintain limestone stone?
General stone with water soak for a few hours or days, with a brush or loofah the moss, repeated washing with water rinse water, until satisfied. Can add when necessary to remove the dirt and smell of weak acids such as oxalic acid is hard, then scrub, but be careful not to hurt the skin of stone. New collection of strange stones, if stained with more dirt, dirt, water can be washed clean, but must not be artificially polished, not to be carved. A polish or polish, has lost the most important characteristics and attributes. Another stone daily maintenance better with a clean cotton cloth dipped in clean water, not oil wax, after a considerable period of time that oxidation will make oil wax into the stone, surface damage, greatly reduce the value of the collection. For the maintenance of strange stones, now mainly use Vaseline, baby oil and other oils to maintain the stones, so that moisture. This method is easy to learn and economical. The oil can also maintain the luster of stone and avoid drying or weathering of stone.
Q:Made of lime preserved eggs to eat for a long time is harmful to health
Many people in the daily life are very fond of eating preserved eggs, lean meat porridge, cold preserved eggs, proper food is indeed very delicious, but if excessive consumption, then the harm to the human body is very serious. Many people do not know that preserved eggs will also affect human health, experts remind eggs this food, no harm, but not excessive consumption. This is due to the process of pickling preserved egg is very complex, usually with tea, lime mud wrapped, so in the production process will use a large amount of catechin, tannic acid and sodium hydroxide, these substances will invade the body protein in eggs.
Q:Lime itself is not water resistant, but some well constructed lime soil has a certain water resistance. What do you think may be the reason?
The calcium hydroxide in contact with the air will also react with carbon dioxide in water and air, and the surface of the membrane will organize the water to enter. Therefore, lime dust will have better strength and water resistance
Q:What does plaster plaster on the wall mean? 18+2?
The plastering is divided into three layers. The first floor and the second layer are 18mm thick, and the last layer 2mm belongs to the surface layer. But now the site is generally wiped two times ash, the thickness reached 20mm on the OK, and even more directly wiped 20mm thick.
Q:When preparing cement lime mixture mortar, the lime paste used in masonry engineering is still available after dehydration and hardening?
In the preparation of cement lime mixture mortar, should be used in accordance with the quality standards of quicklime. In order to ensure the quality of the mortar, it is necessary to make the lime into lime paste before use. Lump lime cured into lime paste, should use the filter pore size is less than 3mm * 3mm, the curing time of not less than 7d; the ground quick lime powder, the curing time should not be less than 2D, to ensure the full maturation of lime. In order to ensure the quality of lime paste, measures should be taken to prevent lime paste from drying, freezing and polluting. Prohibit the use of dehydration hardened lime paste.
Q:What is the compressive strength of limestone? Thank you
To 2.7t/m3, the compressive strength, vertical bedding direction generally 60 ~ 140MPa, parallel bedding direction generally 50 ~ 120MPa, loose coefficient generally 1.5 ~ 1.6.
Q:What are the differences between lime and cement in production and use?
Calcium oxide is mixed with water to produce [slaked lime], which produces a strength hardening environment that is carbon dioxide in the air and is reacted with carbon dioxide to form calcium carbonate. But we all know that the strength of calcium carbonate is not high, so the lime is mainly used for decorative materials, or to fill the gap tiles.
Q:What's the difference between cement mortar and cement mortar? Just the difference between adding lime?
The cement mortar is composed of cement and sand mixture + + water, sometimes adding a certain amount of additives (such as waterproof agent, antifreeze, early strength agent, mainly used as what) this mixture strength in above the same proportion of cases the highest intensity. Generally used for exterior wall pasted wall, wall light etc.;
Q:Is the desiccant lime or slaked lime?Why can't ammonia be dried with concentrated sulphuric acid?
A drying agent is a lime. It can hydrate with hydrated lime and can dry. And slaked lime has no effect. It does not react with water
Q:Water lime can be used as disinfectant
The lime white lumps or powder, the main composition of calcium oxide, calcium hydroxide and water can produce heat, commonly known as slaked lime, strong alkalescence, moisture absorption is very strong. Lime can kill various pathogenic bacteria, but ineffective against spores, mainly used for disinfection of walls, floor, septic tanks and sewage ditch.
We can produce quality limestone 6 million tons (CaCO3>=97%,stable), active calcium oxide 1.50 million tons, light calcium carbonate 100 thousand tons and calcium hydroxide 100 thousand tons every year. And our products has been exported to Asia, Africa, Australia, America, etc.. and we sincerely hope to cooperate with the clients from all over world. Hope we would gain together in the future!
