纖維素—上海甄準(zhǔn)

纖維素—上海甄準(zhǔn)

堿纖維素被不同的醚化劑取代而得到不同的纖維素醚。按取代基的電離性能,纖維素醚可分為離子型(如羧甲基纖維素)和非離子型(如甲基纖維素)兩大類。按取代基的種類,纖維素醚可分為單醚(如甲基纖維素)和混合醚(如羥丙基甲基纖維素)。按可溶解性不同,可分為水溶性(如羥乙基纖維素)和有機(jī)溶劑溶解性(如乙基纖維素)等。

干混砂漿主要用水溶性纖維素,水溶性纖維素又分為速溶型和經(jīng)過(guò)表面處理的延遲溶解型。

上海甄準(zhǔn)生物提供α-纖維素、羥丙基甲基纖維素、羥丙基纖維素、羥乙基纖維素、三醋酸纖維素、硝酸纖維素、乙基纖維素和乙酸丁酸纖維素。
