做重庆伸缩遮阳蓬应该如何正确选择膜材呢?

来源:未知时间:2017-04-12
膜材的准确选定用于修建济南伸缩遮阳蓬的膜材,依涂层材不一样大致可分为PVC膜与PTEF膜,膜材的准确选定应思考其修建的规模大小、用处、形式,运用年限及核算等归纳要素后决议。
Accurately select the membrane material for membrane material to build the Ji'nan retractable awning, according to different coating materials can be divided into PVC membrane and PTEF membrane, the membrane material should be selected accurately on the construction of the size, form, use, use period and accounting elements after induction resolution.

PVC膜材在资料及加工上都比PTFE膜廉价,且具有材质柔软,易施工的长处。但在强度、经用年限、防火性等性能上较PTFE膜差。PVC膜材是由聚脂纤维织物加上PVC涂层(聚氯乙烯)而成,通常修建用的膜材,是在PVC涂层材的外表处理上,涂以数micron厚的压克力树脂(acrylic),以改进防污性。但是,经过数年以后就会变色、污损、劣化。通常PVC膜的经用年限,依运用环境不一样在5~8年。为了改进PVC膜材的耐侯性,这些年已研宣布以氟素系树脂于PVC涂层材的外表处理上做涂层,以改进其耐侯性及防污性的膜材。
PVC membrane material in the material and processing are cheaper than the PTFE film, and has the advantages of soft material, easy construction. But in the strength, the use of years, such as the performance of fire resistance than the PTFE film. PVC membrane is made of polyester fabric with PVC coating (PVC) and film material for the building, usually, is in the appearance of PVC coating material, coated with acrylic resin micron thickness (acrylic), to improve the antifouling properties. However, after a few years later will discoloration defiled degradation. Usually PVC film by the number of years, according to the use of the environment is not the same as in 5~8. In order to improve the corrosion resistance of PVC membrane material, these years have been announced to do research of fluorine coating surface treatment in PVC resin coating material, to improve its corrosion resistance and anti fouling of membrane material.
PVDF
PVDF
PVDF是二氟化树脂(Polyvinylidene Fluoride)的略称,在PVC膜外表处理上加以PVDF树脂涂层的资料称为PVDF膜。PVDF膜与通常的PVC膜对比,经用年限改进至7~10年左右。
PVDF is two (Polyvinylidene Fluoride) of the fluoride resin, PVDF resin coating in appearance on PVC film material called PVDF film. PVDF film with the usual PVC film contrast, after the use of improved to about 7~10 years.
PVF
PVF
PVF是一氟化树脂(Polyvinyl Fluoride)的略称。PVF膜材是在PVC膜的外表处理上以PVF树脂做薄膜状薄片(laminate)加工,比PVDF膜的耐久性更佳,更具有防沾污的长处。但由于加工性、施工性与防火性都欠安,所以运用用处受到限制。
PVF is a fluorinated resin (Polyvinyl Fluoride) the abbreviation. PVF membrane is in the appearance of processing PVC film on PVF resin film sheet (laminate) processing, than the PVDF film durability is better, more anti contamination strengths. But due to the processing and construction of fire and are not good, so the use of restricted use.

PTFE膜是在超细玻璃纤维织物上,涂以聚四氟乙烯树脂而成的资料。PTFE膜最大的特微即是耐久性、防火性与防污性高。但PTFE膜与PVC膜对比,资料费与加工费高,且柔软性低,在施工上为防止玻璃纤维被折断,须有专用治工具与施工技能。
PTFE film is a kind of superfine glass fiber fabric coated with PTFE resin. PTFE membrane is the most special micro durability, fire resistance and high pollution resistance. However, PTFE film and PVC film contrast, data and processing costs high, and low flexibility, in order to prevent the construction of glass fiber to be broken, there must be special treatment tools and construction skills.
耐久性:涂层材的PTFE对酸、硷等化学物质及紫外线十分安靖,不易发生变色或破裂。玻璃纤维在经长期运用后,不会导致强 度劣化或张力减低。膜材色彩通常为白色、透光率高,耐久性在25年以上。
Durability: coating materials for PTFE acid, alkali and other chemical substances and UV is very quiet, not easy to change color or rupture. Glass fiber after long-term use, will not lead to strength deterioration or tension reduction. The color of the film material is usually white, high transmittance and durability for more than 25 years.
防污性:因涂层材为聚四氟乙烯树脂,外表摩擦系数低,所以不易污染,可藉由雨水洗净。
Antifouling: because the coating material is PTFE resin, the surface friction coefficient is low, so it is not easy to pollute, can be washed by rain.
防火性:PTFE膜契合近一切国家的防火资料实验合格的特性,可代替其它的房顶资料做平等的运用用处。
Fire resistance: PTFE film fit nearly all of the country's fire resistance test of the characteristics of qualified, can be used in place of other roofing materials do equal use.
