一、真空绝热板(VIP)简介:
真空绝热板(VIP板)是英文Vacuum Insulation Panel的简称,是真空保温材料中的一种,是由填充芯材与真空保护表层复合而成,它有效地避免空气对流引起的热传递,因此导热系数可大幅度降低,小于0.003w/m.k,并且不含有任何ODS材料,具有环保和高效节能的特性,是目前世界上最先进的高效保温材料。
二、真空绝热板(VIP)应用:
国内近几年开始制造并采用VIP改良冰箱隔热层,整个冰箱制造业似乎刮起了一阵VIP应用试验的大风潮,再反观国外一些发达国家对VIP的研究和使用已经有十多年的历史,以及二十世纪中国制造业的崛起与国家节能政策的颁布实施,VIP这种超强新型的保温材料正被商家所关注,市场前景广阔。
VIP主要用于保温绝热,如家用冰箱、游艇冰箱、迷你冰箱、车载冰箱、深冷冰柜、电热水器、自动贩卖机、冷冻箱、冷藏集装箱、建筑墙体保温和LNG储运等。
VIP板在冷藏设备中的应用
◆冰箱采用VIP隔热:可以节能10%~30%,并且增加有效容积20%-30%。尽管现在VIP的价格还偏高,但用户使用冰箱7~10年节约的电费,已相当于冰箱采用VIP隔热增加的费用。采用VIP隔热,除了经济意义外,还有冰箱重量轻,体积小的优点。冰箱门和冷冻箱的上开门,要求质轻、壁薄,采用VIP隔热有较大的技术经济意义。
◆以蓄冷材料维持低温的冷藏箱:用PU或PF保温时,保温期只有1~2天;采用VIP隔热材料后,保温期延长至4~5天,使原来必须空运的物品,可以改用卡车运输或者火车运输,大幅度降低了运输费用。
◆冷藏保温箱:在内装保温物品相同的情况下(1) 用PU泡沫时,外形尺寸57cm×50cm×50cm,保温层厚度3.8 cm,内装21.8 kg冷却剂,保温期120 h;(2) 用VIP隔热时,外形尺寸33cm×46cm×28cm,保温层厚度2.5cm,内装7 kg 冷却剂,保温期200 h。采用VIP新材料后,保温箱体积减少70%,冷却剂减少68%,而保温期则延长66%。减少了运费,提高了运距,经济效果明显。
三、真空绝热板(VIP)优势:
同其它材料相比,VIP以其极低的导热系数,在保温技术要求相同时有保温层厚度薄、体积小、重量轻的优点,适用于节能要求较高的产品,有较大技术经济意义。
四、真空绝热板(VIP)状况:
目前国内研发真空绝热板的企业屈指可数,国内的vip真空隔热板质量与国外也有些差距,但是凭借着中国制造的低成本和低碳经济的备受关注,使我们在市场上也有一席之地。
五、真空绝热板(VIP)芯材区分:
目前vip真空绝热板区分粉体芯材和玻纤芯材,粉体芯材则采取纳米级气象二氧化硅为材料的真空绝热板,在应用中无环境污染,生产制作和使用中对人体无任何危害,而玻纤芯材的真空绝热板在应用中则有局限性
A, vacuum insulation panel (VIP) introduction:
Vacuum Insulation panels (VIP) in English Vacuum Insulation Panel
for short, is one of the Vacuum thermal Insulation material, by filling the
composite core material and Vacuum protection surface layer, and it effectively
avoid caused air convection heat transfer, thus can greatly reduce the thermal
conductivity, is less than 0.003 w/m.k, and does not contain any ODS material,
has the characteristics of environmental protection and high efficiency and
energy saving, is currently the world's most advanced and efficient heat
preservation material.
Second, the vacuum insulation panel (VIP) application:
Domestic in recent years began to make and use VIP improved
refrigerator heat insulation layer, the refrigerator industry seems to be
revealed a great agitation, VIP application test again in some developed
countries abroad research and use of VIP has ten years of history, as well as
in the twentieth century the rise of China's manufacturing industry with the
promulgation and implementation of the national energy conservation policy VIP
this super new thermal insulation material is attention by merchants, wide
prospect of market.
VIP is mainly used for thermal insulation, such as household
refrigerator, yacht refrigerator, mini refrigerator, car refrigerator,
cryogenic freezer, electric water heater, vending machines, freezers, cold
storage container, building wall thermal insulation and LNG storage and
transportation, etc.
VIP plate in the application of refrigeration equipment
VIP is adopted for the refrigerator heat insulation: can energy
saving 10% ~ 30%, and increase the effective volume by 20% - 20%.Though the VIP
price is still high, but the user use the refrigerator 7 ~ 10 years to save
electricity, is equivalent to the refrigerator using VIP insulating increased
costs.The VIP insulation, besides economic significance, and the refrigerator
light weight, the advantages of small volume.The refrigerator door and cooler
on the door and asked for qualitative light, thin wall, adopt the VIP
insulation has great technical and economic significance.
To maintain the low temperature cooler cool storage material: with
PU or PF insulation, heat preservation period only 1 ~ 2 days;After using VIP
insulating materials, heat preservation period extended to 4 ~ 5 days, which
must be air freight items, you can switch to trucking or train transportation,
greatly reduce the transportation cost.
Refrigerated incubator:, install thermal insulation items (1)
under the condition of same with PU foam, shape size 57 cm by 50 cm by 50 cm,
thermal insulation layer thickness of 3.8 cm, built-in 21.8 kg, coolant heat
preservation period of 120 h.(2) using VIP insulation, shape size 46 cm x 28
cm, 33 cm x insulation layer thickness of 2.5 cm, within 7 kg coolant, heat
preservation period of 200 h.After using VIP new materials, heat preservation box
volume decreased by 70% and 68% less coolant, and heat preservation period is
extended by 66%.Reduced the freight, the distance was improved, and economic
effect is obvious.
Three, vacuum insulation panel (VIP) :
Compared with other materials, VIP, with its extremely low
coefficient of thermal conductivity of insulation layer thickness in the same
thermal insulation technology requirements are thin, the advantages of small
volume, light weight, suitable for energy saving products, high demand has great
technical and economic significance.
Four, the condition of vacuum insulation panel (VIP) :
There is few domestic research and development of vacuum
insulation panel enterprises, internal and overseas VIP vacuum insulation board
quality have some gap, but with made in China, much attention has been paid to
low cost and low carbon economy that we also have a place in the market.
Five, the vacuum insulation panel (VIP) core material to
distinguish:
Current VIP vacuum insulation board to distinguish the powder core
material and glass fiber core material, nanoscale meteorological silica powder
core material is taken as the material of vacuum insulation panel, no
environmental pollution in the application, production and use of no harm to
human body, and glass fiber core material of vacuum insulation panel has
limitations in application
