融雪有关诗句,例如:“雪花飞暖融香颊。颊香融暖飞花雪。”
出自:《菩萨蛮》
宋·苏轼
雪花飞暖融香颊。颊香融暖飞花雪。欺雪任单衣。衣单任雪欺。别时梅子结。结子梅时别。归不恨开迟。迟开恨不归。
作者简介:苏轼(1037-1101),北宋文学家、书画家、美食家。字子瞻,号东坡居士。
“氯盐类”融雪剂的融雪原理是:“氯盐类”融雪剂溶于水(雪)后,其冰点在零度下,如,氯化钠(食盐主要成分)溶于水后冰点在-10℃,氯化钙在-20℃左右,醋酸类可达-30℃左右。
盐水的凝固点比水的凝固点低,因此在雪水中溶解了盐之后就难以再形成冰块。此外,融雪剂溶于水后,水中离子浓度上升,使水的液相蒸气压下降,但冰的固态蒸气压不变。为达到冰水混和物固液蒸气压等的状态,冰便融化了。这一原理也能很好地解释了盐水不易结冰的道理。简单地说,就是融雪剂降低了雪的熔点,使其更容易融化。我们知道,水是一种特殊的物质,即结冰后密度变小(一般物质固态下的密度大于液态下的密度),因此,压强越大,冰的熔点越低。常常见到,车轮碾过的地方雪往往易于融化就是这个道理。积雪的路面上洒上融雪剂后,再经车辆的碾压就更易使雪融化。综上可见,洒上融雪剂后就有利于除雪.可以用煤渣或热水。
煤渣可以吸收阳光加快溶解速度(冰雪是白色的,只反射阳光,不吸收阳光)。通常煤渣认为是黑色的,吸收能量效果好。
利用热水或者热融雪剂溶液,将其喷洒在院子路上,不仅利用热液体的热能,同时利用和发挥融雪剂降低冰点的作用,使得积雪能快速消融。
①【成分】融雪盐是指氯化钠(NaCl)、氯化钙(CaCl2)、氯化镁(MgCl2)、氯化钾(KCl)等,一种或几种溶于水(雪)后,其冰点在零度下。
②【原理】盐水的凝固点比水的凝固点低,因此在雪水中溶解了盐之后就难以再形成冰块。

西安天道化工有限公司 13891988646 029-86259515 以“氯盐”为主要成分的无机融雪剂,如氯化钠、氯化钙、氯化镁、氯化钾等,通称作‘化冰盐’。
其优点是价格便宜,仅相当于有机类融雪剂的1/10,但它对大型公共基础设施的腐蚀是很严重的。我们常见的融雪剂就属于这类.融雪盐的原理:
1、盐的溶解使含盐雪水的凝固点降低,因此在雪水中溶解了盐之后就难以再形成冰块。
2、其原因是,融雪盐溶于水后,水中离子浓度增大,使水的液相蒸气压下降,但冰的固态蒸气压不变。为达到冰水混合物平衡共存时固液相蒸气压相等的状态,冰便融化。故洒上融雪盐可以除冰雪。 融雪盐的成份是NaCl,和雪接触后,它是要溶解的,这里有个溶解平衡,平衡向着,盐完全溶解的方向进行,这样,雪就在溶化,为盐提供溶解质水。

食盐可以融雪。
这要从盐的化学成分说起。盐的成分是氯化钾,雪的成分是水。氯化钾是极溶于水的化学物质。氯化钾溶于水后生成氯化钾水溶液,其中含有钾离子和氯离子。水要结冰时,有氯离子和钾离子存在时,氯离子和钾离子会破坏水的结晶网状结构,使水不能结冰。也就是说,盐能使雪不结冰。再说,盐的代价便宜,并且没有污染。因此,下雪时,经常给路面撒盐,防止雪水结冰。
一般下雪路面上使用的是融雪盐,融雪盐是指氯化钠、氯化钙、氯化镁、氯化钾等,溶于水(雪)后,其冰点在零度下。盐水的凝固点比水的凝固点低,因此在雪水中溶解了盐之后就难以再形成冰块。
融雪盐理化特性:
①可溶性.
容易溶解在水中,常见的物理现象。
②吸潮性.
融雪盐的表面通常被一层薄膜状的饱和盐溶液所包围,当这层薄膜溶液的蒸气压低于空气中水蒸气分压时,融雪盐就吸附空气中的水分而潮解;反之,当高于空气中水蒸气分压时则呈现干燥状态.当然,这只是在融雪盐被暴露在空气中才有的现象,密闭在包装袋中与周围空气隔绝的融雪盐是不会潮解的。
③冰点低
实验表明,如果融雪盐溶液里含有20%的盐分,它的冰点就会降低到-16℃。
资料扩展:
融雪剂主要分为两大类,一类是以醋酸钾为主要成分的有机融雪剂,虽然这一类融雪剂融雪效果好,没有什么腐蚀损害,但它的价格太高,一般只适用于机场等地。而另一类则是氯盐类融雪剂,包括氯化钠、氯化钙、氯化镁、氯化钾等,通称作‘化冰盐’。它的优点是便宜,价格仅相当于有机类融雪剂的1/10,但它对大型公共基础设施的腐蚀是很严重的。
氯盐类融雪剂的除雪作用有两点,除了盐类的溶解吸热以外,还有一个作用就是盐水的凝固点较低,因此在雪水中溶解了盐之后就难以再形成冰块,从而有利于排雪。
雪融剂溶于水后,水中离子浓度上升,使水的液相蒸气压下降,但冰的固态蒸气压不变.为达到冰水混和物固液蒸气压等的状态,冰便溶化了。这一原理也很好的解释了盐水不易结冰的道理。
潍坊坤阳化工有限公司年产5万吨融雪剂,融雪剂原料易得,价格低廉,其成份主要是醋酸钾和氯盐,并以这两种进行分类。融雪剂通过降低冰雪融化温度融化道路上的积雪,便于道路疏通,播撒处效果明显,但其具有危害性,研究发现,融雪剂残留物可腐蚀路面和汽车橡胶轮胎。
目前北方在常冬下仍采用沙土和铲雪车为主,融雪剂为辅的方式清除路面冰雪。

"Chloric salt kind " the slushy principle of slushy agent is: "Chloric salt kind " slushy agent dissolve at water (snow) hind, its freezing point falls in zero, be like, sodium chloride (salt bases) dissolve is in at the freezing point after water - 10 ℃ , chloridize calcium is in - 20 ℃ left and right sides, acetic acid kind can amount to - 30 ℃ left and right sides.
Briny freezing point is lower than the freezing point of water, because this dissolved in slush,ice cube is formed again hard after salt. In addition, slushy agent dissolve after water, ionic chroma rises in water, make the fluid photograph vapour pressure of water drops, solid state vapour pressure of Dan Bing is constant. The condition that waits to achieve vapour pressure of fluid of solid of content of mix up glacial water, ice melted. This one principle also can explain the reason that brine freezes not easily well. Say simply, it is the melting point that slushy agent dropped snow, make its melt more easily. We know, water is a kind of special material, decrescent of the density after freezing namely (the density that the density below general material solid state is more than liquid state to fall) , accordingly, intensity of pressure is greater, glacial melting point is lower. Often see, the local snow that the wheel has ground often melts easily is this truth. Asperse on the road surface of firn on after slushy agent, again of classics car grind pressure make Xue Rong is changed more easily. See on put together, asperse on be helpful for dividing snow after slushy agent.Can use cindery or hot water.
Cindery and OK absorb sunshine to accelerate deliquescent rate (ice and snow is white, reflex sunshine only, do not absorb sunlight) . Normally cindery consider as black, it is good to absorb energy effect.
Use hot water to perhaps heat up slushy agent solution, spray its go up in courtyard road, use hot liquid heat energy not only, be used at the same time and develop slushy agent to reduce the effect of freezing point, make firn can fast melt.
① [composition] slushy salt is to point to sodium chloride (NaCl) , chloridize is calcic (CaCl2) , magnesium chloride (MgCl2) , potassium chloride (KCl) , one plant or a few kinds of dissolve at water (snow) hind, its freezing point falls in zero.
② [principle] briny freezing point is lower than the freezing point of water, because this dissolved in slush,ice cube is formed again hard after salt.

13891988646 029-86259515 of limited company of chemical industry of Xi'an weather channel with " chloric salt " the inorganic and slushy agent that is bases, wait like calcium of sodium chloride, chloridize, magnesium chloride, potassium chloride, appellative make ' the salt that melt ice ' .
Its advantage is low-cost, be equivalent to only organic the 1/10 of kind of slushy agent, but it is right of large and public infrastructure corroding is very serious. Our common slushy agent belongs to this kind.The principle of slushy salt:
1, of salt deliquescent the freezing point that makes contain saline slush is reduced, because this dissolved in slush,ice cube is formed again hard after salt.
2, its reason is, slushy salt dissolve after water, ionic chroma increases in water, make the fluid photograph vapour pressure of water drops, solid state vapour pressure of Dan Bing is constant. The status with equal vapour pressure of photograph of fluid of the solid when coexisting evenly to achieve mixture glacial water, ice melts. Reason is aspersed on slushy salt can divide ice and snow. The component of slushy salt is NaCl, after be being contacted with snow, it should dissolve, here has a deliquescent balance, side with evenly, the direction that salt dissolves completely undertakes, such, snow is in dissolve, provide solvency water for salt.

Salt is OK and slushy.
This should become defend oneself to rise from saline chemistry. Saline composition is potassium chloride, the composition of snow is water. Potassium chloride is extremely dissolve the chemical material at water. Potassium chloride dissolve makes potassium chloride aqueous solution after water, contain potassium ion and chloric ion among them. When water should freeze, when chloric ion and potassium ion exist, chloric ion and potassium ion can destroy the crystal and reticulate structure of water, make water cannot freeze. That is to say, salt can make snow not frozen. Besides, saline cost is cheap, and do not have pollution. Accordingly, when snowing, often spill salt to road surface, prevent slush to freeze.
Snow commonly what use on road surface is slushy salt, slushy salt is to point to calcium of sodium chloride, chloridize, magnesium chloride, potassium chloride to wait, dissolve at water (snow) hind, its freezing point falls in zero. Briny freezing point is lower than the freezing point of water, because this dissolved in slush,ice cube is formed again hard after salt.
Slushy salt manage changes character:
① dissolubility.
Dissolve easily in water, common physical phenomenon.
② sucks wet sex.
The surface of slushy salt is surrounded by the place of saturated salt solution of a filmy shape normally, the vapour pressure when this filmy solution is divided under the vapor in air when pressing, slushy salt is divided with respect to the water in adsorptive air and deliquescence; Conversely, present dry position when cent presses the vapor in prep above air. Of course, this just is exposed to be in air in slushy salt ability some phenomenon, airtight in wrapping bagging with all round the slushy salt with completely cut off air is won't of deliquescence.
③ freezing point is low
The experiment makes clear, if the salinity of 20% is contained in slushy salt solution, its freezing point can be reduced - 16 ℃ .
The data is patulous:
Main component is slushy agent two kinds big, one kind is the organic and slushy agent that is bases with acetic acid Potassium, although this kind of slushy agent is slushy the effect is good, corrode without what damage, but its price is too high, apply to airport and other places only commonly. And another kind is chloric salt kind slushy agent, include calcium of sodium chloride, chloridize, magnesium chloride, potassium chloride to wait, appellative make ' the salt that melt ice ' . Its advantage is cheap, the price is equivalent to only organic the 1/10 of kind of slushy agent, but it is right of large and public infrastructure corroding is very serious.
Chloric salt kind the action dividing snow of slushy agent has at 2 o'clock, besides salt kind beyond deliquescent absorption of heat, the freezing point that still having an effect is brine is inferior, because this dissolved in slush,ice cube is formed again hard after salt, be helpful for discharging snow thereby.
Dissolve of agent of snow be in harmony after water, ionic chroma rises in water, make the fluid photograph vapour pressure of water drops, solid state vapour pressure of Dan Bing is constant. The condition that waits to achieve vapour pressure of fluid of solid of content of mix up glacial water, ice was dissolved. The explained brine freezes not easily reason with this one very good also principle.
Limited company of chemical industry of female this world produces per year Wei lane 50 thousand tons of slushy agents, slushy agent raw material is easy, the price is low, its component basically is acetic acid Potassium and chloric salt, undertake classified with these two kinds. Slushy agent melts through reducing ice and snow temperature melts the firn on road, facilitating road dredge, spread place effect apparent, but its have harm sex, consider to discover, slushy agent hangover can corrode road surface and car balata tire.
At present north still uses sandy soil and shovel snow car to give priority to below Chang Dong, slushy agent is complementary means is cleared road surface ice and snow.
