摘要:
A novel silver-containing tobermorite usable in place of silver-, copper- or zing-incorporating zeolites and having ethylene-adsorbing ability and antibacterial properties. Stated more particularly, a silver-containing tobermorite having a composition of [Ca.sub.5-Y/2 Ag.sub.Y+Z M.sub.x-z (Si.sub.6-x Al.sub.x O.sub.18 H.sub.2).4H.sub.2 O, 0.ltoreq.X.ltoreq.1, 0.001.ltoreq.Y.ltoreq.2, 0.ltoreq.Z.ltoreq.0.1, M is a monovalent cation] and prepared from a tobermorite [Ca.sub.5 M.sub.x (Si.sub.6-x Al.sub.x O.sub.18 H.sub.2).4H.sub.2 O, 0.ltoreq.X.ltoreq.1, M is as defined above] by exchanging Ca.sup.2+, or Ca.sup.2+ and a monovalent cation which are interlayer ions of the tobermorite for silver ion. The silver-containing tobermorite is excellent in heat resistance, water resistance and mechanical strength, and also outstanding in ethylene-adsorbing ability and antibacterial properties.
摘要:
A composition containing a function improver and an inorganic porous crystals-hydrophilic macromolecule composite wherein the hydrophilic macromolecule contains inorganic porous crystals in its inner matrix, and a product made therefrom The product, textile, nonwoven fabric, paper and laminate obtained from the composition of the present invention come to have high strength in addition to the gas adsorption capability, volatile organic solvent removing capability, noncombustibility, heat insulating property, and heavy metal and radioactive element removing capability that the inorganic porous crystals-hydrophilic macromolecule composite (A) possesses. It is also possible to improve a touch and the like, so that the composition is useful as a material having additional functions.

摘要:
An inorganic porous crystals-hydrophilic macromolecule composite comprising a hydrophilic macromolecular substrate containing the inorganic porous crystals in its inner matrix, production method thereof and use thereof. The present invention affords an inorganic porous crystals-hydrophilic macromolecule composite comprising the inorganic porous crystals held in the inner matrix of the hydrophilic macromolecular substrate. This composite is particularly superior in adsorption of metal ion, specifically silver and copper ions, and the metal-holding inorganic porous crystals-hydrophilic macromolecule composite showed noticeably strong adsorption of hydrogen sulfide and the like, so that it can be used as a deodorizer, antimicrobial material and freshness retention material for fruits and vegetables.
