Fluorescent whitening agent 31 has a strong whitening effect in synthetic washing powder and also has excellent whitening effect on materials such as cotton fabric , paper and jinglun 荧光增白剂31用在合成洗衣粉中，对洗衣粉本身的外观增白作用强，洗涤效果也好，对棉织物、纸张、棉纶也有很好的增白作用，用后可使增白物发亮。
In food industry taurine can be added to dairy products , beverage , monosodium glutamate and bean products . taurine can accelerate the differentiation and development of nerve cell , enhance immunocompetence 本品亦可用作表面活性剂、调湿剂、乳化剂、荧光增白剂、 ph缓冲剂、洗涤剂中间体和化学试剂，水产、动物养殖饲料添加剂等领域。
In addition , we designed a test : the midgut was removed from spodoptera exigua larvae and was cut longitudinally into halves , the midgut epithelia were cleaned and digested with dispase ii , the pelleted cells in grace medium with 7 % fbs supplemented with 100units / ml penicillin , 100ug / ml streptomycin were cooled and then suspended in r18 - labelled virus 实验结果表明，在幼虫的病毒接种物中添加合适浓度的荧光增白剂( 0 . 01g . ml一’ )不会改变病毒在幼虫中肠组织中的感染部位，却可以提高幼虫对病毒的敏感性，增加了病毒毒力。
Suggesting that the larvae of spodoptera exigua died more quickly when fb - 28 were added to the virus . the larvae of spodoptera exigua inoculated as newly molted fourth instars ( 40s ) and at various hours after molting ( 316s ) , we sacrificed larvae at various time intervals after inoculation to process the larvae for lacz expression in midgut by using tissue section techniques on early phase infection 此外，对于处于不同虫龄的幼虫进行病毒感染时发现：对3 ~ ( 16 )幼虫毒力生物测定时，荧光增白剂的增效作用达到50 ，但对4龄初的供试幼虫进行测定，荧光增白剂的增效作用却不很明显，仅为10 。
The foci located the basal in midgut not in control but also in test , the results showed that the addition of optical brighteners did n ' t change the spots of infection but improved the viral enhancement , in addition , infection of hemolymph cell showed that optical brightener increased sensitivity of larvae to virus , forming more foci 可见，对于处于不同时龄的供试幼虫接种病毒时，添加荧光增白剂均可提高病毒在中肠组织中的感染能力。从病毒在中肠中形成的病灶部位可以看出，实验组与对照组的病灶均靠近中肠的基底膜，荧光增白剂的加入并不能改变病毒在中肠组织的感染部位。
It has been rated aaa enterprise for years by the agricultural bank of china henan branch and honored many times by related authorities . dongyuan chemical s main products are dsd acid ( 5 , 000 ts ) , ansd acid ( 1 , 000 ts ) , dnsd acid ( 1 , 500 ts ) , 2 - methyl - 5 - nitrobenzenesulfonic acid ( 1 , 300 ta ) , basic dyes and dye intermediates 公司注册商标为“东园”牌，其中主导产品dsd酸年产能力为5000吨，年产ansd酸为1000吨，对硝基甲苯邻磺酸1300吨，二硝基酸1500吨，并生产荧光增白剂系列产品、碱性染料、直接染料及染料中间体。
Zbd model whiteness measurement meter is mainly applicable to measurement of the whiteness of colourless even surface objects and powder , such as paper , pulp , ceramics , enamel , plastics , enamel , plastics , various fiber and fabric , wheat flour , talcum powed , starch , coating and chemicals etc . it canalso measure comparatively accurately the fluorescent whiteness of the objects with fluorescentbrighterner Zbd型白度测定仪主要用于测量非彩色表面平整的物体及粉末的?白度? ,如纸张,纸浆,陶瓷,搪瓷,塑料,个种织维及其织品,面粉,滑石粉,淀粉,涂料及化工产品等,对于添加荧光增白剂的物品,本机也能比较准确的测量其?荧光白度? 。
