The results showed that there existed variation among eucalypt families in wood physical-mechanical properties and wood chemistry. There were significant differences among E.pellita families、E.grandis families and E.urophylla譋.grandis clones in wood colors as well as between Strains and within trees.The variation of the surface wetability of wood between E.grandis families and E.urophylla譋.grandis clones were significant.Even in the same families level or clones level,there still existed the same regulation. The degree of collapse of eucalypt had a large relation in the amount of tylosis in vessel and vestured pits on the cell wall of vessel. The more rich tylosis and vestured pits in vessels,the more probability to occur collapse for eucalypt.The biggest moment collapse was probably the critical point of the drying degrade.During the fomulation of drying technology,it is necessary to adopt moderate condition to make the vessels which had formed the biggest moment collapse at the biggest moment collapse resume,especially to prevent the permanent set.At the normal temperature level,the main factors which influenced residual collapse were the contents of ray parenchyma and axial parenchyma .Nearly all the cells joined the course of forming the moment collapse and biggest moment collapse.Interval drying was fit for eucalypt plantation which was easier to make collapse.
研究表明:桉树不同家系间木材物理力学性质和化学组成存在差异;粗皮桉家系间、巨桉家系间、尾巨桉无性系间材色存在显著差异,株间、株内木材材色存在变异;桉树木材表面润湿性在巨桉家系间、尾巨桉无性系间存在着显著差异,在同一家系或同一无性系中,株间和株内也存在着相同的变化规律;桉材皱缩程度与其导管中侵填体的多少和导管壁上纹孔具有的附物多少密切相关,侵填体含物越丰富,纹孔附物越多,桉材越容易皱缩;最大瞬间皱缩是能产生更大干燥降等的临界点,在制定干燥工艺时,必须在最大瞬间皱缩发生时,采用温和条件,使已产生最大瞬间皱缩的细胞尽可能多的恢复,尤其不能使其产生永久变定;在常温条件下,影响残余皱缩的主要因子是射线薄壁细胞和轴向薄壁细胞含量;而对于瞬间皱缩和最大瞬间皱缩,几乎所有细胞都参与它们的形成过程;对于易皱缩的桉树木材,间歇干燥是最有前途的干燥方法。

The invention relates to a processing method of preventing frostbite and restarting of hydrogen electric pile, whose characteristic lies in the treating processes includes: When the electric pile turns off, the unsaturated fuel gas or the nitrogen, through the circle boast to clean the dissociate water; drying the MEA film module to keep the water content below the stipulated temperature which does not ice up; then the recycle gas through a wet exchanger to dry and the dried gas is continue used in the dry pile step; when restarting the electric pile, the recycle gas must heats then through the pile to elevate the temperature, then heats the fuel gas and the oxidant of the gas source, through the weting of the wet exchanger enters to the calefactive pile, enhances the wet step of the film module in the pile, starts the power output of the pile.
本发明涉及一种氢电堆的防冻和重新启动时的处理方法,其特征在于处理过程包括:电堆停机时,将水蒸气不饱和的燃料气体或氮气,通过循环吹扫除去电堆的游离水;干燥其中的MEA膜组件,使膜组件含水量降低到规定低温下不结冰的程度;而后再令循环气体通过一个湿交换机将循环气体干燥,以及被干燥后的循环气体继续用来干燥电堆的步骤;在电堆重新启动时,须将循环气体加热后通过电堆,使电堆升温,然后再将气源的燃料气及氧化剂加热,通过湿交换机加湿后进入已升温的电堆,提高电堆中膜组件的湿度的步骤,开始电堆的功率输出。

When infrared ray irradiates to the surface of material and radiating frequency is same as material molecular frequency, the radiating energy is strongly absorbed by the material.
红外辐射是辐射物体以电磁波的方式传播内能的过程,当红外线照射到某一物体时,如果入射的红外线频率和物体分子固有频率相一致,则物质分子就会表现出对红外线的强烈吸收,吸收的那一部分能量就转化为分子的热运动,使物体温度升高,达到加热干燥的目的。

Two-component waterborne polyurethane paint composed of acrylic dispersion and hydrophilically-modified polyisocyanate has fast dry time, good adhesion, flexibility, impact resistance, but poor water and chemical-resistance. The dry time becomes shorter with the increase of glass transition temperature and the decrease of acid value; the gloss of the film decreases with the increases of hydroxyl value, acid value and Tg of emulsion polymer; higher Tg polymer leads to harder film.
将制得的丙烯酸分散体与亲水改性多异氰酸酯组分配制水性双组分聚氨酯涂料,发现漆膜表干和实干比较快,干燥时间随玻璃化温度升高而缩短,随酸值的增加而增加;附着力、柔韧性和冲击强度比较好;光泽随分散体羟值、酸值的增加和玻璃化温度升高而降低;硬度随玻璃化温度升高而升高;较高的酸值使涂料的耐化学品性和耐水性较差,羟值在100mgKOH/g时较好,而酸值应尽可能低。
