Patent JO-3693-B1 (JO)
Title: A process for production of pure phase zeolite ZSM-5 from raw kaolinite
Inventor: RASHA RAWAJFH
IPC: C01B39/18
Filed: 2017-10-16
Granted: 2020-08-27
Abstract: The invention relates to a process for the production of pure phase zeolite ZSM-5 in a good yield using high silica raw kaolinite as a source of silicon and aluminum. The process comprises heat treatment of raw kaolinite to convert to metakaolinite followed by acid/base treatment of metakaolinite. The process involves dissolution of the silica and alumina components of metakaolinite and the removal of the solid residue that does not react with either the acid or the base used. The pH of the alkaline aluminosilicate solution was adjusted from 9 to 13, and the hydrogel formed was crystallized hydrothermally in an autoclave at a temperature from 100 to 180 degree C. The process allows the production of pure phase zeolite ZSM-5 with variable SiO<sub>2</sub>-to-Al<sub>2</sub>O<sub>3</sub> ratios.

Title: Coated abrasive product having radiation curable binder
Inventor: BOETTCHER THOMAS E
IPC: B24D3/28
Filed: 1986-08-06
Granted: 1994-04-25
Abstract: This invention relates to coated abrasive products having a resinous binder which holds and supports abrasive granules on a backing sheet. 
<??>In the manufacture of coated abrasives, the make coat resinous binder and abrasive granules are first applied to the backing, then the size coat resinous binder is applied, and finally, the construction is fully cured. Generally, thermally curable binders provide coated abrasives having excellent properties, e.g. heat resistance. 
<??>With polyester or cellulose backings, however, curing temperatures are limited to about 130 DEG  C. At this temperature, cure times are long. The long cure times necessitate the use of festoon curing areas. Disadvantages of festoon curing areas include formation of defects at the suspension rods, inconsistent cure on account of temperature variations in the large festoon ovens, sagging of the binder, and shifting of abrasive granules. Furthermore festoon curing areas require large amounts of space and large amounts of energy. 
<??>This invention provides a coated abrasive product comprising abrasive granules adherently bonded to at least one major surface of a backing sheet by a radiation curable resinous binder material. The binder material can be used to form the make coat, size coat, or both coats. Alternatively, the binder material can be used in embodiments where only a single binder coat is employed. The radiation curable resinous binder material comprises a copolymer formed from a mixture comprising (1) at least one monomer selected from the group consisting of isocyanurate derivatives having at least one terminal or pendant acrylate group and isocyanate derivatives having at least one terminal or pendant acrylate group, and (2) at least one aliphatic or cycloaliphatic monomer having at least one terminal or pendant acrylate group.
