PC板的内应力构成于挤出成型及冷却定型的过程中,而在PC板的外形基本上没发作任何改动的放置或许运用过程中,将经历一个应力松懈效果,有些的消除可一些内应力。可是只是经历有限的松懈的PC板很难彻底消除这些应力,再其内留有应力,假定在运用过程中不注意增大外在的应力,将会发作面层的有些变形而且接近于外表而从此处于现易破点(纤细的开裂、裂纹)。因而,咱们在运用中有必要防止那些不正确的或许过火的外部应力
PC board of internal stress in the process of extrusion and cooling to finalize the design, and the appearance of the PC board basically didn't attack the placement of any changes may use in the process, will experience a stress lax effect, some eliminate to some internal stress. But only limited experience lax PC board is very difficult to eliminate the stress, stress, which have assumed in use do not pay attention to during the process of increasing external stress, surface will attack and close to the appearance of some deformation and from then on is now easy to break point (fine crack, crack). Therefore, we in the use of it is necessary to prevent the incorrect perhaps far external stress
致使PC板材开裂的要素有许多，主要和板材的方案、选材、施工等方面的联络比较大。假定方案不合理，选材不正确，或许是在施工的过程中没有做好一些很细节的方面，都会致使PC板材开裂。
Led to many PC plank crack elements, the main sheet and the methods, materials, construction and other aspects of the contact is larger. Assume that plan is not reasonable, select material is not correct, may be in the process of construction was not well done some very details, will cause the PC board crack.
假定PC板材放置的环境过火湿润或许单调都会有欠好的影响，过于湿润会发作胀大，过于单调又会发作缩短，这么最简略致使PC板材开裂了，关于这些疑问，咱们处理的办法有：
Assume that humid environment of the PC board placed far maybe monotonous will have owe good, too wet will attack swell, too monotonous and can shorten, so the brief that PC plate cracking, about these questions, let's processing method are:
能够运用机械的办法，强行PC板材呈现胀大或许缩短；
Able to use mechanical approach, forced swell may shorten the PC board presented;
在木材加工的过程中，能够改动加工的办法，防止呈现开裂的景象；
In the process of wood processing, can change the processing method, prevent craze of rendering;
在PC板材的两头和外表涂上防水涂料，这么能够下降木材外表的蒸腾湿度，削减木材开裂的程度；
At the two ends of the PC board coated with waterproof coating and appearance, so can lower transpiration humidity appearance of wood, cut wood craze degree;
对木材进行高温处理，削减开裂的概率；
Heat treatment of wood, cut down the probability of cracking;
运用防水剂，这么能够做好防水处理，就不会呈现开裂的状况了。
Using the waterproofing agent, so can good waterproof processing, will not be presented the status of the cracking.
