Criathar móilíneach

  • Saghas
  • Is criostal microporous sileacáit é criathar móilíneach (ar a dtugtar zeolite sintéiseach freisin). It is a basic skeleton structure composed of silicon aluminate, with metal cations (such as Na +, K +, Ca2 +, etc.) to balance the excess negative charge in the crystal. Tá an cineál criathar móilíneach roinnte den chuid is mó i gcineál, cineál x agus y de réir a struchtúir chriostal.

Clóscríobh criathar amolecular

 1

Is é an príomh -chomhpháirt de chriathar móilíneach Cineál A ná aluminate sileacain. The main crystal hole is octaring structure.The aperture of the main crystal aperture is 4Å(1Å=10-10m), known as type 4A (also known as type A) molecular sieve; Exchange the Ca2 + for the Na + in the 4A molecular sieve, forming an aperture of 5A, namely a 5A type (aka calcium A) molecular sieve;K+ for a 4A molecular sieve, forming an aperture of 3A, namely a 3A (aka potassium A) molecular sieve.

Cineál X criathar móilíneach

The main component of X molecular sieve is silicon aluminate, the main crystal hole is twelve element ring structure.Different crystal structure form a molecular sieve crystal with a aperture of 9-10 A, called 13X (also known as sodium X type) molecular sieve;Ca2 + exchanged for Na + in a 13X molecular sieve, forming a molecular sieve crystal with a aperture of 8-9 A, ar a dtugtar criathar móilíneach 10x (ar a dtugtar cailciam x) freisin.
