    瓦楞紙板的硬度達(dá)標(biāo)注意事項(xiàng)!

    來(lái)源:http://www.zywygg.com 發(fā)布時(shí)間:2021-08-11

    1.  如果紙板水分過(guò)高,預(yù)熱輥溫度達(dá)不到要求,須增加鍋爐蒸汽壓力,使之供出的蒸汽達(dá)到飽和蒸汽,一般情況下蒸汽壓力應(yīng)該保持在1.1Mpa±0.2Mpa。
    1. If the moisture content of the paperboard is too high and the temperature of the preheating roller cannot meet the requirements, the boiler steam pressure must be increased to make the steam supplied reach saturated steam. Generally, the steam pressure should be maintained at 1.1MPa ± 0.2MPa.
    2.  如果水分偏低,就要調(diào)節(jié)導(dǎo)紙輥,減少預(yù)熱面積,同時(shí)要充分利用單面機(jī)上噴霧裝置(濕潤(rùn)輥),對(duì)原紙進(jìn)行噴霧,增加原紙水分,使之達(dá)到標(biāo)準(zhǔn)要求。
    2. if the moisture is low, adjust the guide roll and reduce the preheating area. At the same time, we should make full use of the spray device on the single plane (Shi Rungun) to spray the base paper and increase the moisture content of the base paper, so as to meet the standard requirements.
    3.  平板烘缸在工作時(shí),不到萬(wàn)不得已時(shí),不能停車。單面機(jī)要更換原紙前應(yīng)提速,在橋架上增加堆積量;復(fù)合機(jī)在接到信號(hào)后應(yīng)降速,待單面機(jī)完成接紙后,再行提速。若設(shè)備發(fā)生故障等必須停車時(shí),應(yīng)將輸送帶提升,以防停留在平板烘缸上紙板水分過(guò)度流失。

    3. When the flat dryer is working, it cannot stop until it is absolutely necessary. Speed up the single-sided machine before replacing the base paper and increase the stacking amount on the bridge; After receiving the signal, the speed of the compound machine shall be reduced, and the speed shall be increased after the paper receiving of the single-sided machine is completed. If the equipment fails and must be stopped, the conveyor belt shall be lifted to prevent excessive loss of paperboard moisture staying on the flat dryer.
    4.  對(duì)于單面機(jī)而言,要調(diào)節(jié)好上膠輥與刮膠輥的間隙。一般情況下,上膠輥與刮膠輥的間隙為0.2mm一0.25mm,涂膠輥與主瓦楞輥在熱機(jī)狀態(tài)下的間隙應(yīng)比所用瓦楞紙的厚度大0.02mm。
    4. For the single-sided machine, the gap between the upper rubber roller and the rubber scraping roller shall be adjusted. In general, the gap between the upper rubber roller and the rubber scraping roller is 0.2mm-0.25mm, and the gap between the rubber coating roller and the main corrugating roller under hot engine state shall be 0.02mm greater than the thickness of the corrugated paper used.
    對(duì)于雙面機(jī)而言,刮膠輥和上膠輥的間隙也為0.2mm一0.25mm,壓輥與上膠輥之間間隙應(yīng)比所通過(guò)的單面瓦楞紙板高度小0.05mm一0.1mm,且兩輥兩端間隙應(yīng)保持一致,可用塞尺測(cè)量。
    For the double-sided machine, the gap between the rubber scraping roller and the rubber feeding roller is also 0.2mm-0.25mm. The gap between the pressing roller and the rubber feeding roller shall be 0.05mm-0.1mm smaller than the height of the single-sided corrugated board passed, and the gap at both ends of the two rollers shall be consistent, which can be measured with a feeler gauge.
    為了有效控制溫度,在瓦楞紙板生產(chǎn)線上,很多地方都設(shè)置了加熱器和烘干板。通常情況下,車速在100m/min以上的瓦楞紙生產(chǎn)線,糊液的固化溫度應(yīng)為160℃~180℃。如果采用蒸汽加熱方式,則要求鍋爐飽和水蒸汽的壓力應(yīng)達(dá)到0.9MPa~1.4 MPa。而瓦楞紙生產(chǎn)線上對(duì)瓦楞紙板含水量影響比較大的設(shè)備主要是單面機(jī)組和烘干機(jī)組。針對(duì)不同情況,應(yīng)該隨時(shí)對(duì)這些部分做出相應(yīng)的調(diào)整,以便生產(chǎn)的順利進(jìn)行。
    In order to effectively control the temperature, heaters and drying boards are set up in many places on the corrugated board production line. Generally, the curing temperature of the paste solution of the corrugated paper production line with a speed of more than 100m / min shall be 160 ℃ ~ 180 ℃. If steam heating is adopted, the pressure of saturated steam of boiler shall reach 0.9mpa ~ 1.4mpa. The main equipment on the corrugated paper production line that has a great impact on the water content of corrugated board are single-sided unit and drying unit. According to different situations, these parts should be adjusted at any time to facilitate the smooth progress of production.
