性能特點(diǎn)：熒光增白劑FBCW是一種目前被認(rèn)為是洗滌劑用的優(yōu)良熒光增白劑。由于這種增白劑分子中引入嗎啉基團(tuán)，使其許多性能得到改善。例如耐酸性能增加,耐過硼酸鹽性能也很好,適用于纖維素纖維、聚酰胺纖維及織物的增白。熒光增白劑FBCW的電離性表現(xiàn)為陰離子性質(zhì),熒光色調(diào)為青光。熒光增白劑FBCW的耐氯漂性能較好，優(yōu)于VBL和31＃，使用最佳染浴的PH＝7～10，其耐曬牢度為4級。FBCW用于洗衣粉中最大特點(diǎn)是：配合量高，積累洗滌白度高，能滿足洗滌劑工業(yè)任何配合量的要求。適用范圍：1、適用于洗滌劑，配入合成洗衣粉、肥皂、香皂中，能使其外觀潔白悅目，晶瑩豐滿。2、用于棉纖維、尼龍等織物增白；對人造纖維、聚酰胺、維尼綸有優(yōu)良的增白效果；對蛋白纖維、氨基塑料也有良好的增白作用。使用方法：熒光增白劑FBCW在水中的溶解度比增白劑VBL和31＃低，可用熱水調(diào)成10%左右的懸濁液使用。配成溶液時，宜隨配隨用，溶液應(yīng)避免陽光直射。熒光增白劑FBCW在洗衣粉中用量為0.08-0.4%；在印染行業(yè)用量為0.1-0.3%。包裝：用鐵桶或紙桶內(nèi)襯塑料袋，每桶凈重20kg或25kg。運(yùn)輸：熒光增白劑FBCW產(chǎn)品運(yùn)輸時應(yīng)避免碰撞和曝曬。貯存：應(yīng)貯存于陰涼、干燥、通風(fēng)的庫房內(nèi)，貯存期兩年。FLUORESCENT BRIGHTENER FBCWC.I.71 CAS：16090-02-1STRUCTURE:FORMULA: C40H38N12O8S2Na2MOLECULAR WEIGHT: 924.93 (As International relative Atom Mass 1997)Max UV ABSORPTION WAVELENGHTH: 350nmEXCUTIVE STANDARD: HG/T 3675-2007SEPCIFICATIONS:

PROPERTY:Optical Brightener FBCW is regarded as one of the perfect agent used in detergent industry. Owing to introducing the morpholine group into the molecular, The properties such as acid and perborate resistence be improved. It can be used in the whitening of cellulose fiber, polyamide fiber and fabrics, showing nionic characters and has optical blue color. It has better resistence to chloride bleaching than VBL and 31#, the most favorable dyeing bath pH value is 7-10. Its sunlight fastness is 4 grade. The most advantage used in detergent industry is its high matching capacity, high accumulated washing whitening effect. So it can meet the requirments of various matching capacity in detergent industry.APPLICATION:1. Used in detergent industry, for the synthetic detergent, toilet soap and soap.2. Used in the fabric of cotton fiber, nylon, etc, taking on excellent whitening effect on artificial fiber, polyamide, vinylon, also has goodwhitening effect on casein fiber, polyamide plastic.PROCEDURE:Optical brightener FBCW has less solubility than VBL and 31#, it can be soluble in hot water and form about 10% solution. The solution should be used immediatly when it is ready and avoid sunlight. The dosage used is 0.1-0.5% in detergent industry and 0.1-0.3% in dyeing industry.PACKAGE: Packed in cardboard bucket or cardboand box after being packed in plastic bag first.Net Weight per bucket is 20kg or 25kg.TRANSPORTATION: Should avoid sunlight and crash.STORAGE: Should be stored in cool,dry and ventilate place, and storage time should not exceed 2 years.
