Silica Fume is often used as cement or concrete admixture in the construction industry, which can fill the pores between cement particles and effectively improve its compressive and water retention properties. The main component of Silica Fume is silicon dioxide,
Odată cu utilizarea din ce în ce mai mare a fumului de micro silice în betonul de ciment, materiale refractare și alte domenii, devine treptat un amestec comun de modificare a materialelor, pentru a face modificarea materialelor mai aplicabilă proiectului, micro silica
Refractory materials are divided into two types, one is the fixed material and one is the indefinite material, the castable refers to the indefinite refractory material. We know that micro silica fume is a good refractory additive, which can improve
Deși fumul de silice este un produs secundar al topirii industriale mari, joacă un rol foarte important în multe domenii industriale, so few people in the relevant industry fields do not know it, silica fume is not only alias a lot,
În general vorbind, the silica content is a measure to test the quality of micro-silica fume. The higher the SiO2 content, the higher the performance of microsilica fume and the lower the content of other non-SiO2 impurities. Prin urmare, the methods of
There are more methods for testing the strength of commercial micro silica fume, and the commonly used methods are rebound method, ultrasonic rebound synthesis method, pull-out method, and core drilling method. Printre ei, rebound method and ultrasonic rebound synthesis method
There are different types of micro silica fume according to different classification criteria. In terms of supply form, it can be broadly divided into two categories, one is the undensified silica fume also said to be the raw silica fume,
Fum de silice, cunoscut și sub numele de fum de microsilice, este o pulbere fină colectată ca produs secundar al producției de siliciu și aliaj de ferosiliciu. The product is used in concrete to improve strength and durability. Low demand for silica fume If you have
Microsilica, or silica fume, is a by-product of the silicon and ferrosilicon alloy production. When these alloys are made, a small amount of silicon dioxide and other materials are vaporized and condensed. This results in a very fine powder ,with
Fum de silice densificat, este o prelucrare ulterioară a fumului de microsilice original pentru a obține un fum de microsilice criptat mai dens.
