efining enzymes“OCE” and “ECO” are complex enzyme preparations intended for use as refining enhancers in papermills using virgin and recyled fibers (inclusive of other lignocellulosic wastes).Choice of “OCE” or “ECO” is dependent on the paper properties required by the end-user, where “OCE ”is an enzyme preparation generally acceptable for most mills “ECO” is recommended where improved compression strength is compulsory. It is easily added to existing systems without the need of complex or specialized equipment and has a broad pH and temperature tolerance. Benefits l Elimination of the need for soda pulping. l Reduction in REFINING ENERGY. Reduction in Refining time or Amperage leading to a reduction in electrical costs. l Improvement in FIBRE YIELD. Increase in fines retention from increased fibrillation (micro-fibrillation).Helps to reduce build-up of fines in forming and press fabrics ,increasing fabric life. l Improvement in WASTEWATER QUALITY. Reduction of fines and the cleaning of white water loops. l Improvement of PAPER STRENGTH properties. Enhances paper strength by increasing inter-fiber bonding through fibrillation (micro-fibrillation). l Improvement in MACHINE RUNNABILITY. Cleaner whitewater system helps to reduce slime build up that causes sheetbreaks. l Reduction in STEAM LOADING or INCREASE IN PAPERMACHINE SPEED. Improvement in drainability leading to either the reduction of steam demand for paper drying or conversely increases in the paper machine speed. l Improvement in PAPER QUALITY. Improvement in paper formation due increased fines retention and more efficiently refined pulp. Reduction in vessel picking during printing of paper produced with hardwood virgin pulp. l Savings in RAW MATERIAL costs .Allows the use of lower quality and cheaper furnishes. l Savings in CHEMICAL costs. Reduction in consumption of retention aids and strength enhancing chemicals. GENERAL INFORMATION Properties Appearance: Tan to orange liquid (Note that color does not affect or reflect activity.) Odor: Slight fermentation odor Solubility: Miscible with water pH (at 30 ℃): 5.5±1.0 Effect of Temperature It will function from 25℃-70℃ with an optimum of 50℃-60℃. Optimum operating temperature results in higher enzymatic activity requiring less dosage of enzyme. Effect of pH It will function from a pH of 4.5-9.0 with an optimum of 7.0. Optimum operating pH results in higher enzymatic activity requiring less dosage of enzyme 生物酶由三组特效酶混合提炼而成，专门用于再生浆-板纸，效果非常明显。此产品为一种中性酵素，最佳操作条件为pH介于5.0-7.0之间；温度为28-75℃，此为一般造纸厂的操作条件。 这种聚合作用可以将浆中的细小纤维重新组合，这是OCE、ECO生物酶具有的第一大特性。当OCE、ECO生物酶加入到再生浆后，它首先遇到了那些停留在浆中的细小纤维，它以大于细小纤维无数倍的数量优势包围了这些细小纤维而使其重新聚合在一起，当这些链合体与长纤维碰撞时，就附着在长纤维上，同时由于OCE、ECO微生物体积很小，被加入到浆中后，即使与长纤维先期接触，也会被碰撞开。但当它们与细小纤维重组后形成了较大的体积时，再加上它本身所具有的粘合性，因此后期再遇到长纤维时自然地与长纤维重新组合.技术总负责王启凌.wangji66@126.com
