In this paper,tensile,elasticity,crimp and boiling-water shrinkage properties of five kinds of fibers,PTT,PTT/PET,PTT/PEBT,high-shrinkage PET and PA fibers,were compared.
文章系统对比分析了PTT、PTT/PET、PTT/PBT、高收缩PET及PA 5种纤维的拉伸性、回弹性、卷曲性及沸水收缩性。
Three ways of sterilization have been adopted:microwave sterilization; high-temperature sterilization and boil water sterilization.
分别采用微波杀菌、高温杀菌和沸水杀菌方式,并在感官、理化、微生物和食品物性方面对杀菌效果进行比较。
The paper introduces how to examine aniois content in the boiled water standed for night by ion chromatography with chemical suppression.
介绍了用抑制型离子色谱法测定隔夜沸水中F-,Cl-,NO2-,H2PO4-,NO3-的含量的方法:流动相为4mmol/L Na2CO3与3mmol/L NaHCO3的混合溶液,流动相流速为1。
The composition,boiling water resistance,steam resistance and other physical properties of a silicone modified urushiol resin corrosion protective paint have been described.
介绍了以有机硅改性漆酚树脂为基料的防腐涂料的构成,及其耐沸水性、耐水蒸汽性及其他理化性能。
74 MPa,the increase ofboiling water resistance was obvious when the mass fraction of melamine was between 43% and 65%,but the increaseof boiling water resistance and wet shearing strength for MUF was non obvious when the mass fr.
74 MPa,耐沸水性明显提高;但是,当w(三聚氰胺)>65%时,该MUF树脂的湿强度增长极其缓慢,其耐沸水性提高并不明显;通过引入复合改性剂和适量的水,可使该MUF树脂的游离甲醛含量降低50%、成本降低10%~15%、固含量基本不变、胶合强度和耐沸水性均有所提高且适用期良好。
