农村用房真石漆主要还是看重耐老化和耐水性及耐洗刷性

(1)耐老化


(1) resistance to aging


将两块玻璃或瓷砖并列放在一同,将不一样漆(A、B、C)比照刷在上边,等枯燥1小时后,把其中一块玻璃放在200oC温度的烘箱内烘2小时,再取出冷却后比照黄变状况,黄变后严峻的标明质量差,耐老化也相应差些。抗阳光辐射性能的好坏通常来说:


The two pieces of glass or ceramic tile tied together, will not be the same boring paint (a, B, c) CF brush on top, 1 hour after, the among them a piece of glass placed in 200oC temperature inside the oven baked for 2 hours, and then remove the cooling after the contrast yellowing condition, Huang bianhou severe indicate poor quality, resistance to aging accordingly. The performance of anti - sun radiation is usually good or bad:


①硅丙、纯丙抗黄变显着优于苯丙漆,苯丙漆优于醋丙漆及普通涂料。


The silicon acrylic and acrylic anti yellow Bianxian is superior to that of styrene acrylic paint, styrene acrylic paint is better than vinegar C paint and ordinary paint.


②即使是不一样厂家的苯丙漆,黄变也会有些差异,这是配方技术上的差异。

Even if it is not the same as the manufacturer of styrene acrylic paint, yellow will also be some differences, which is the difference in the recipe technology.


(2)耐洗刷性及耐水性


(2) washing resistance and water resistance


①从刷样外观看:有光漆的耐洗刷性都大于哑光漆,所以高级外墙漆涂料通常都是半哑光(或蛋壳光),(有光漆因反光太大,对施工平整度请求高及漂亮因素致使未能遍及选用)。有光漆的耐洗刷性通常超越2000次,有些乃至超越20000次。所以用刷子刷已很难比照高光漆之间的差异。


From the brush like outside to watch: gloss paint of abrasion are more than matte paint, so senior paint for exterior wall coatings are usually semi matte (or shell), (gloss paint for reflective too big, to level the construction requirements and beautiful factors resulting in failure to throughout the selection). Gloss paint resistance is usually more than 2000 times, and some even more than 20000 times. So it is difficult to use a brush to contrast the difference between high gloss paint.


②有光或半哑光漆耐水性的比照:可以刷漆膜(均匀抹涂)于玻璃上,干后浸入清水中比照,调查起泡、起皮、掉落程度。起泡越多越快,则耐水性亦越差。


Light or semi matte paint on the water resistance of CF: can brush paint film (evenly coated) on glass, contrast to the dry after immersion in water, sparkling survey, skin, fall degree. The more the bubble, the worse the water resistance.


③同样是两种哑光漆,其耐水性的不同也能差异:


The same is two kinds of matte paint, the water resistance of different differences:


a、将两种漆膜用清水淋一下,无变化的较优异;有发湿和发暗的欠好,是中低档漆;会发软潮化的最差,可能是不合格品。


A, the two film with water pouring, no change is excellent; wet hair and dark hair owe good is in low-grade paint; weak tide of the worst may be substandard products.


b、用指甲刻划一下两种干漆膜,硬的质量好,树脂粘结剂多,耐水性优;软的则差,本钱也低。


B, with a nail scratching about two kinds of dry film, hard good quality, resin binder, water resistance is excellent; soft is poor, the cost is low.
