EPS泡沫板是一種優(yōu)良的包裝材料,如電視機(jī)、冰箱、空調(diào)、玻璃器皿、陶瓷等商品,離不開泡沫包裝作為緩沖包裝。 EPS泡沫板是由聚苯乙烯樹脂和發(fā)泡材料加熱發(fā)泡后制成的輕質(zhì)材料。 EPS具有泡沫輕、導(dǎo)熱系數(shù)低、吸水率低、耐水性低、耐老化等優(yōu)點。是蔬菜保鮮、保溫盒保鮮等的容器,EPS泡沫板簡單回收再利用。它是一個綠色包裝。
EPS foam board is a good packaging material, such as TV, refrigerator, air conditioner, glassware, ceramics and so on. Cannot do without foam packaging as cushion packaging. EPS foam board is made of polystyrene resin and foamed material after heating and foaming. EPS has the advantages of light foam, low thermal conductivity, low water absorption, low water resistance and aging resistance. It is a container for keeping fresh vegetables and keeping fresh boxes. EPS foam board is simply recycled and reused. It's a green package.
EPS是一種有機(jī)碳?xì)浠衔?。一般的EPS制品除了發(fā)泡后呈多孔狀態(tài),含有殘留石油氣外,都是易燃的。它們可以被火點燃并在燃燒時發(fā)光。即使它們離開火焰,它們也會繼續(xù)燃燒,伴隨著煙霧和熔滴。自燃和外燃溫度分別為490℃和296℃。沒有阻燃劑的普通EPS泡沫被歸類為“易燃”。遇火燃燒,火焰迅速蔓延至整個表面。如果存在足夠的氧氣并且排放了煙霧,EPS 將完全燃燒。因此,在儲存和使用過程中要注意,特別是不要遇到明火,要嚴(yán)格隔離其他火源,注意原料倉庫等生產(chǎn)場所的通風(fēng)。 EPS燃燒時,可用所有消防器材滅火,也可用水滅火。
EPS is an organic hydrocarbon. The general EPS products are flammable except that they are porous after foaming and contain residual petroleum gas. They can be ignited by fire and glow as they burn. Even if they leave the flame, they will continue to burn, accompanied by smoke and droplets. The temperature of spontaneous combustion and external combustion are 490 ℃ and 296 ℃ respectively. The ordinary EPS foam without flame retardant is classified as "flammable". In case of fire, the flame spreads rapidly to the whole surface. If there is enough oxygen and smoke is emitted, the EPS will burn completely. Therefore, in the process of storage and use, we should pay attention, especially not to encounter open fire, strictly isolate other fire sources, and pay attention to the ventilation of raw material warehouse and other production places. When EPS burns, it can be put out with all fire fighting equipment or water.
在防火中要考慮的另一個因素是熱量的釋放。 EPS的燃燒值為40436KJ/kg,這并不一定意味著EPS泡沫燃燒時會釋放大量熱量。在這種情況下,主要因素是燃燒速度。
Another factor to be considered in fire prevention is the release of heat. The burning value of EPS is 40436KJ/kg, which does not necessarily mean that the EPS foam will release a lot of heat when it burns. In this case, the main factor is the burning rate.
由于它們是輕量級物品,當(dāng)EPS用作隔熱和包裝材料時,它不會釋放大量熱量以支持火災(zāi)中的燃燒。
Because they are lightweight, when EPS is used as insulation and packaging material, it does not release a lot of heat to support combustion in a fire.
EPS泡沫的著火性能(除材料本身的性能外)還取決于許多因素,包括幾何性質(zhì)、表面積、與其他物品的近似程度、火源、復(fù)合結(jié)構(gòu)、火源的性質(zhì)和能量,面對火源的時間,以及熱處理和通風(fēng)。
The ignition performance of EPS foam (except for the properties of the material itself) also depends on many factors, including geometric properties, surface area, approximation to other articles, fire source, composite structure, nature and energy of fire source, time of facing fire sources, heat treatment and ventilation.
在評估 EPS 泡沫使用中涉及的火災(zāi)危險時,應(yīng)考慮所有這些因素。表面覆蓋、分層和與其他材料復(fù)合可以改變產(chǎn)品的耐火性。
All these factors should be considered when assessing the fire hazards involved in the use of EPS foam. Surface covering, lamination and compounding with other materials can change the fire resistance of products.
EPS產(chǎn)品用于建筑、造船、冷藏車等領(lǐng)域時,必須提出一定的阻燃要求。阻燃EPS原料由于加入了有機(jī)鹵化物等阻燃劑,大大改變了其燃燒性能,擴(kuò)大了EPS的應(yīng)用范圍。
When EPS products are used in construction, shipbuilding, refrigerated vehicles and other fields, certain flame retardant requirements must be put forward. Due to the addition of flame retardants such as organic halides, the combustion performance of flame retardant EPS is greatly changed, and the application scope of EPS is expanded.
雖然長時間暴露在火焰中可能會被點燃,但火焰蔓延到其整個表面的速度非常緩慢。當(dāng)外部火焰移開時,EPS泡沫不會繼續(xù)燃燒,也不會留下任何余輝。這表明EPS泡沫不會完全燃燒,除非直接受到其他更易燃物質(zhì)的影響。。
Although it may be ignited when exposed to the flame for a long time, the flame spreads to the whole surface very slowly. When the external flame moves away, the EPS foam will not continue to burn and will not leave any afterglow. This indicates that the EPS foam will not burn completely unless it is directly affected by other more flammable substances.
