技術說明

本發明之改質黏土複材可在細菌表面聚集，而濃度過高之改質黏土將抑制細菌生長，其可應用於農漁業、生醫產業、複合材料及改質黏土的製備。1.抗菌機制：包覆病毒、細菌、蟲卵；使其不分裂繁殖孵化。2.增進植物生長： 增加光合作用的量，使植物生長加速，且生長的體積較大。3. 增加土地利用率：使用本發明噴灑農地後，經由農友實地測試後發現，木瓜年產量增加四成，不需要輪耕，且有平衡土壤酸化之功能。4.多元應用性：由於脫層黏土與界面活性劑的複材，故可大範圍的使用在不同用途上。例如：抗菌－減少農藥用量或代替農藥、 促進生產－將土壤改質由酸性變鹼性、促進光合作用－植株且茂密、促進果實早熟－木瓜提早一個月成熟、吸附農藥－減少產品農藥殘留、防腐劑－增長農產品保留期限、豬舍之除臭－抗菌（防禽流感）及消滅蚊蠅滋生（防登革熱）等。 The present invention discloses the compositions of silicate clay and surfactant complex that comprise of nanoscale silicate platelets (NSP) and organic components comprising of surface active agents including anionic, cationic and nonionic types. The NSP is sodium form of randomized silicate platelets that derived from the exfoliation and extraction of layered silicate natural clays. The inorganic NSP is modified by organic moieties such as the common organic surfactants through ionic exchange reactions. The ionic exchange reaction between NSP and cationic surfactants such as fatty quaternary ammonium chloride or bromide salts produces NSP/cationic complexes. The charge association between NSP and cationic surfactant is strong, by measuring the surface tension. The generated complexes are active ingredients for antimicrobial, soil remedy and promoting agricultural product growth which is demonstrated by improving the fruit harvests.
