hydrosoluble การใช้

• 2 . in order to deeply probe into the influence of crosslinked degree on er properties and expediently characterize the structure of the supramolecular complex , six hydrosoluble - cyclodextrin polymer / 3 - hydroxy - 2 - naphthoic acid er particles were synthesized . fluorescence analysis conformed that all the polymers can form 1 : 1 type supramolecular complex with the guest
• 3 . considering the shortcomings of hydrosoluble - cyclodextrin polymer , such as easily water - absorbed properties and poor endurance in a high electric field , two - cyclodextrin - starch resin electrorheological particles ( wss - - cdp and cls - - cdp ) were synthesized by copolymerization through a mixture of - cyclodextrin and epichlorohydrin in the presence of water - soluble and water - insoluble starch , respectively . the structures of these polymers were characterized by ft - ir and raman s
• This paper mainly deals with the effect of hydrosoluble hp fibre , fibremesh and fdn on cement mortar ' s bend resistant strength and compressive strength under the same operating conditions and with different hp mixtures ; comparing fibremesh to hp , both of which have different effects on concrete ' s compressive strength , tensile strength and bend resistant strength ; and finally discussing hp ' s mechanism
• Based on this point , our aim to obtain the high performance materials should be carried out as well as the er behavior be actualized through the chemistry design . in this paper , 4 supramolecular complexes of - cyclodextrin inhydrosoluble polymer / l - ( 2 - pyridlazo ) - 2 - naphthol , 6 hydrosoluble - cyclodextrin polymer / 3 - hydroxy - 2 - naphthoic acid , 2 - cyclodextrin - starch resins and 6 supramolecular complexes of - cyclodextrin - starch copolymer / substituted salisylic acid and 3 - hydroxy - 2 - naphthoic acid er particles were prepared , respectively . the structure of these particles was characterized by ir , nmr , uv - vis , the fluorescence analysis , element analysis , and etc , respectively
• The results indicate that hp can promote the toughness and strength of cement mortar and concrete , and with the increase in hp mixture , compressive strength increases more obviously than bend resistant strength does ; with the hydrosoluble hp fibre added , the microstructure of mortar or concrete will change , the space web structure will be formed , which consists of mixed hydrates and hp films . as a result , the performance of mortar and concrete , with high strength and few apertures , can be improved
