本发明为一种木紋玻镁外墙挂板的生产工艺， 包括制木紋模板与制木纹玻镁板两 个工序， 制木紋模板的工艺流程为：
制作一张与所需制作玻镁外墙挂板的尺寸相同的木紋紋路胶片。 在制作木纹紋路 胶片时， 可按照所需制作玻镁外墙挂板的紋路， 选择与其纹路近似的原木木板， 并制 作一张与所需制作玻镁外墙挂板的尺寸相同的原木木板， 刷除掉原木木板表面的软木 质表层， 留出原木木板表面的木紋纹路， 按玻镁外墙挂板所需效果对木紋紋路的深浅 加工到位， 用数码相机照下原木木板表面的木紋纹路， 根据此纹路制作一张与所需制 作玻镁外墙挂板的尺寸相同的木纹纹路胶片。 木紋纹路也可以在电脑上直接制作， 然 后根据纹路制作一张与所需制作玻镁外墙挂板的尺寸相同的木纹纹路胶片。
制作一个轧辊， 把胶片的木紋紋路通过感光投影法复制到轧辊上， 并用电解腐蚀 液对轧辊进行腐蚀， 腐蚀掉不需要的部分， 留出木纹纹路。再对轧辊进行镀硬铬处理， 使轧辊表面硬度达到 模板的可行性硬度；
把轧辊安装到压制模板的设备上， 根据模板所需材料， 压制出各种材料的模板。 检查所压制的模板， 查看紋路是否符合玻镁外墙挂板所需的木纹紋路， 选出合格的模 板备用。
制木纹玻镁板的工艺流程为：
主要原材料的准备： 调配 mgcl2生产溶液，确认 MgO的活性和纯度，测量木屑或珍 珠岩粉的干湿度。 MgC12是玻镁外墙挂板的两种主要原料之一， 它的质量要求主要有两方面， 一是 MgC12的有效含量， MgC12 43% , 钙离子 Ca+含量 0. 7%； 另一方面是碱金属氯化 物（以 C1一计） 1. 2% , 因为 Ca+与 C1一的含量将直接影响制品的稳定性与泛霜性。
配制 mgcl2溶液时， 先把卤片（固体 mgcl2)倒入水池中， 加入自来水溶解， 加水 量根据卤水浓度的需要而定。 卤水浓度根据 MgO的活性、 木屑或珍珠岩粉的干湿度、 空气湿度和环境温度来制定。 MgO的活性、 温度越高， 木屑或珍珠岩粉的相对湿度、 含水率越低，则卤水浓度越低，反之则卤水浓度越。卤水浓度浓度范围为 20° 〜30° 。 环境温度， 空气湿度、 Mgo 的活性等发生变化都要调整卤水的浓度， 配制卤水要在卤 片下池的当天进行， 使卤片在水中完全溶解， 并调配到所需要的浓度， 调配好的卤水 温度会很高， 要等到其温度下降到 30°C以下才能使用， 所以配制卤水要在生产用卤水 前约 15小时进行。
辅助原材料的准备： 在生产流水线上安装好玻纤布滚筒和无纺布滚筒。
主要原材料的搅拌混合： 将主要原材料按照一定比例和程序进行搅拌混合， 并根 据生产时的空气湿度和环境温度确定搅拌时间的长短，湿度大和温度低则搅拌时间长。 例： 相对湿度 90%、 温度 15°C要 5分钟， 相对湿度 40%、 温度 30°C要 3分钟。 使主 要原材料充分均勾的混合， 形成符合生产要求的料浆。 生产前首先要检查打浆机和搅 拌机是否运行正常， 搅拌分为打浆和打料， 这两个过程要同时进行。
打浆： 先放入配制好的的卤水到打浆机里， 再倒入 Mg0， 立即加盖搅拌， 1〜2分 钟后停机， mgcl2溶液与 MgO的配比为： 1升 mgcl2溶液需加 l〜2Kg的 Mg0。 放下浆子 前要把软管里的一小部分卤水放到预备好的小桶里，确保放下的料浆里没有注的卤水， 然后将料浆放下。 MgO也是玻镁外墙挂板的两种主要原料之一， 采用轻烧 MgO的原料, 其 MgO含量 为 80%〜85%， 活性 MgO含量 <) 60±2%， CaO含量 <1. 5%， 烧失量为 5 %〜9% , 细度为 170目。
打料： 先将木屑或珍珠岩粉倒入搅拌机里， 机器运转 3〜5转， 再倒入 Mg0， 转动 机器， 同时加入配制好的卤水， 2分钟后再加木屑或珍珠岩粉， 一共搅拌 7〜8分钟即 可下料， 同时根据木屑或珍珠岩粉水份的髙低， 对卤水的量进行微调。 木屑或珍珠岩 粉含泥量应〈1 %， 细度在 20〜60目， 含水率应〈25%， 材料不应霉烂变质。
生产流水线的开机准备： 生产前要对机器试运行， 把皮带和料斗用水打湿， 检查 机器运行是否正常， 确定无异常后停机。 检査和调整轧辊运行是否正常， 确定无异常 后停机。 检查和调整轧辊间隙， 第一道轧辊间距为 10. 4ram， 第二道轧辊的间距为 10. 6mra, 同时把玻纤布和无纺布上架并送入轧辊， 调整玻纤布和无紡布的张力。
送模板： 把喷好脱膜 （模） 剂的木紋模板送上生产流水线。 先清除木纹模板上的 灰尘和垃圾， 然后喷脱膜剂， 喷脱膜剂要均匀， 点面俱到， 不能多喷和漏喷， 把喷好 的木紋模板送上制板机， 要求每张都要首尾相连， 不能有缝隙和重叠。
刮浆： 先在木紋模板上刮第一层桨， 然后铺玻纤布， 再在玻纤布上再刮第二层浆， 刮浆时要求在木紋模板底面不泛花的情况下愈薄愈好， 不能一块薄一块厚， 浆子厚薄 不匀， 会使板子易变形， 易断裂。 第一层浆的厚度为 0. 2〜0. 5讓， 第二层浆的厚度为 0. 1〜0. 3 腿。
原材料的混合轧制： 将主要原材料的料浆与辅助原材料在木纹模板上进行混合， 并经过生产流水线的两道轧辊进行产品轧制成形。
下料： 第二层浆上铺一层料， 一次性下料不能太多也不能过少， 下料太多会造成 缩板， 缩板过多， 板子的长度就不够， 使产品成为废品； 下料过少， 压出的板子不密 实， 容易造成缺料， 使产品厚薄不勾。 料层厚度为 6〜12mm。 铺完料后， 在料层上甫 一层玻纤布， 再在玻纤布上铺一层无紡布。 两层玻纤布和一层无纺布要整平， 不能有 绉折。
切断： 把机器上生产出来的连体板子按两块木紋模板的接缝用美工刀划开， 当机 器上的板子运行到切断区域时， 要及时切断， 板子切断后要初步修整板面， 特别是两 端， 如遇缺料要及时填补。
产品下线上架： 运行的板子在到达尾架之前， 要及时上好托架， 而且放上去的托 架不能歪斜。
一级养护： 产品上架后， 立即送入一级养护区养护。 一级养护区环境温度应保持 在 20°C〜30°C之间， 板子进入一级保养区放好后， 要进固化前的最后修整， 用刮板刮 去板面上的细小波紋和两端滴下的料桨，经过 18〜24小时的保养后，固化成型率达到 90%以上， 即可脱模。
二级养护： 将完成一级养护的产品送入二级养护区进行堆放保养， 产品堆放的髙 度不得超过 1. 2米。二级养护区环境温度应保持在 10°C〜35 °C之间，保养时间为 10〜 28天。
浸泡排卤： 将完成二级养护的产品放入排卤池， 放入清水浸泡， 8〜15小时后抽 干污水， 再次放入清水， 浸泡 8 15小时， 然后起吊放入晒场。 若采用免泡技术， 则 可不要进行泡晒排卤。
晾晒： 将产品送入晾晒区， 晾晒区环境温度应保持 20°C 4(TC之间， 并可以进行 通风排湿， 晾晒 7 9天。
切割： 将完成晾晒的产品送入切割设备， 按要求的尺寸进行切割。
喷涂底层防护漆： 将完成切割的产品进行除尘清洁后， 喷涂产品底层防护漆 （白 色)， 在环境温度 10°C 35°C之间摆放 2 6小时后， 即可进行成品检验打包。
