        【摘 need 】 control separation quality, 一方面 need can can control stability large film 卷, 原辅材 material quality;另一方面, more need according to 实际情况 for separation process and adjustment, make separation quality can can improve/increase. different types type plastics film property can different, separation methods in 一定差异.

         纵 toward strip/profile 纹 

        纵 toward strip/profile film surface formed ring toward 肋线状 strip/profile 纹. in separation 切/复卷 process in a large amount of gas and thick degree 公差不佳 is generate toward strip/profile main/primary causes, 一旦出现程 degree relatively is heavy strip/profile very difficult remove. its causes is separation speed degree fast 导致. generally 说, in high speed lower most easy 发生纵 toward strip/profile and and other quality issues.

         错层 

        指 film 卷端面 upper has separation film phenomenon, is film in process in sliding or film wide degree 发生变化 致. 错层首先同样 and separation speed degree has 关, accelerated, decrease speed speed, for slip property good film easy generate slip formed 错层, slow speed degree 变化. film 卷卷取 紧也会 make film 发生横 toward slip 移, film 卷 松会造 formed gas 卷入, 都会造 formed film 卷端面错层, adjustment 取卷张 force.

         底皱 

        底皱仅仅发生于 film 收卷开始 一段 long degree in, performance is and strip/profile more deep, its generate multiple factors 致. in process parameters upper, different type type separation machine, process parameters setting methods, methods, value is different.

        例如: separation machine through adjustment 收卷马达 electrical pressure control 收卷张 force use machine abrasion scratch retardant force to 放卷张 force, new separation machine use electrical according to process parameters control and 放卷马达 to most combined 适 收, 放卷张 force, between parameters setting 就根本 different.

         equipment property can and film inner in property can for film separation 切收卷 quality has very large effect/influence, is combined process can improvement toward strip/profile 纹, and other quality issues. different equipment and different type type specifications film need using/adopting separation process, equipment 状况变化时也 can through process adjustment to 予弥补, process adjustment must heavy.

         another, separation 切工序 most important 原辅材 material is and large film 卷, its quality good bad effect/influence separation speed degree, but also and toward strip/profile 纹, and other issues related, need using/adopting process control, 进货检验 and most 终检验 versus combined methods add strong/high 监控, stability large film and 原辅材 material quality.

         翘边 

        翘边发生 in film 收卷 边缘位置, is thick film 边缘经收卷叠 add make 边缘部位翘起. usually causes is 切刀太钝, separation in 切口处 generate tensile phenomenon, formed rear film 卷边缘 toward outer 翻翘导致翘边, 此时应 and more 换切刀, can 避免翘边 issues 发生. tool 安装不 positive 确, speed degree fast, 卷取太紧时也 easy generate 翘边.

         暴筋 

        暴筋 is due to film thick degree 公差偏 thick 累积而 in film surface formed obvious 突起. this main/primary is film quality 导致, film quality is by separation already molding large film or by again separation formed product quality, 例如: film thick thin 公差, film 收卷状态 and other, for separation rear film table/sheet quality has important effect/influence, quality low poor film make separation 切/复卷也无 method to 令人满意 table/sheet quality.

         separation is improvement local issues can full issues, need to good product table/sheet and quality, 一方面 in separation 切时进行适当 adjustment, 另一方面必 must requirements front formed film improve/increase quality.

          long degree 不足, wide degree large  

         this is due to 收卷计数错误 or by separation film long degree 不足, and equipment 定位不 positive and other causes 引起. is meet/satisfy use need to long degree film 卷, generally lower, as can from machine upper data to long degree.

        但 is production in 往往会遇 to film and large film surface separation film and other 情况, if according to long degree 进行计算 and 配切, to separation most rear 才发现 long degree 不够而 also method 进行拼接, 则整车 product method formed is positive product, especially is wide to 1 米 above separation machine, loss more large.

         is this type of 情况 发生, according to Model/Grade, specifications, process same large film long degree and film 卷直径呈一定 for 应关系, need in upper machine rear will amount to data for 照收卷 long degree can large 致知道 film 卷 卷 long is combined requirements, if versus relatively large in 配切时 attention/notes long degree, long degree phenomenon 发生.

          film inner has 灰尘甚至 small and other material  

         film in separation process in, need by heavy new 打开然 rear again 复卷, this is outer material 进入创造 conditions. also due to many film product need and food, product and other 直接接触, therefore for requirements separation 严格, production workshop for ensure product 清洁良 good separation important.
