针式打印机断针的原因及维护

引起打印机断针的原因很多,概括起来有以下几个方面。 1. 使用了劣质色带盒和色带。在打印过程中,因劣质色带盒的盒盖与盒体结合不紧。很容易从动齿轮脱离原位,与主齿轮咬台不紧,使色带松弛。如果使用的色带质量差,色带油墨会沿着打印针导孔进人打印头针缝并固化,使打印头出针阻力增大,容易引起断针或压坏打印针平行槽,更严重时会使打印针驱动芯片或色带电机及驱动芯片烧毁。 2. 色带安装不合理。转动时打印头两面的色带反向、

数字热转印打码的技术优势

数字热转印打码机主要由打印头、打印色带及控制器组成。打印头通常每毫米包含8至12个点或每英寸200～300个点（DPI），这些点可迅速地连续开关，从而将油墨从色带转印到薄膜上，以打印影像。由于采用数字化手段，打码机可“实时”打印，并可以非常迅速地为间歇及连续包装更改批号及日期信息。     

基于GemDialogue色卡研究光源对绿松石颜色的影响

本文基于CIE 1976 L~*a~*b~*均匀色空间,在D_(65)光源、F_2光源和A光源下采用便携式测色仪对GemDialogue色卡中与天然绿松石颜色相匹配的952组色带进行颜色测试,并通过CIE DE2000色差公式对"绿松石颜色"色带进行颜色指数分析。结果表明,D_(65)光源下"绿松石颜色"的明度值更高、彩度值居中,更贴近于人眼在日光下的颜色感知;F_2光源由于紫区存在高能辐射,与D_(65)光源相比,其绿—蓝系列色带的彩度值略低,而蓝—紫系列色带的彩度值较高;A光源由于红区高能辐射,与D_(65)光源相比中高彩度色带的彩度值更高,且对蓝色色带的彩度强化更显著,同时红色调对绿色、蓝色的中和作用导致整体"绿松石颜色"色调范围的减小。

Effect of Inoculation of Pectinolytic Mixed Bacterial Culture on Improvement of Ribbon Retting of Jute and Kenaf

Abstract

Jute and kenaf are among the annually renewable fibre crops mainly grown over tropical and subtropical Asian countries. They are possibly the world's largest source of lignocellulosic bast fibre which is extracted from plants by a natural microbial process known as retting. But acute shortage of water for retting and the environmental pollution created from conventional system of retting has demanded for new method of retting.

The new method of retting launched has been recognized as ribbon retting. In ribbon retting barks are removed from jute and kenaf plants mechanically or manually in the form of ribbon. The ribbons are coiled and then allowed for retting in water with or without using a microbial inoculum. Ribbon retting has the following advantages over conventional retting: (1) It requires lesser volume of water, (2) it is faster, (3) it produces lesser environmental pollution, and (4) it produces improved quality fibre. Addition of efficient pectinolytic microbial inoculum may further boost up or improve the ribbon retting process.

From the present study it is understood that inoculation of a specific mixed bacterial culture in combination with 0.5% urea as N-supplement caused faster ribbon retting of jute and kenaf. Ribbon retting conducted in cement retting tank was faster than that in polythene tank. The mixed bacterial culture in combination with urea produced stronger, finer and brighter coloured jute and kenaf fibre in comparison to uninoculated control. One hundred twenty-day-old plant was found most suitable for ribbon retting. Ribbon retted fibre with pectinolytic mixed bacterial culture in combination with urea obtained higher grade in comparison to uninoculated control. Such ribbon retted fibres produced standard and regular quality yarn.

EFFECT OF FROZEN STORAGE ON THE FUNCTIONAL PROPERTY OF RIBBON FISH (TRICHIURUS SAVALA) CUVIER

The ribbon fish (Trichiurus savala) is an important marine fish caught along the coast of Orissa, India amounting to 9.2% of total marine fish catch. The possibility of using frozen ribbon fish to make surimi was investigated. At 1 month interval, fish were thawed under controlled conditions and gels were then made from minces of the flesh. Both puncture and torsion tests showed that the quality of gels declined by 30% after 30 days of storage and thereafter nonsignificant reduction up to 100 days storage of frozen ribbon fish at − 20C. This decline was correlated by a decrease in pH and an increase in formaldehyde concentration in the frozen flesh. The data suggest that a land-based surimi plant could not be operated outside the harvesting season to any appreciable extent using frozen ribbon fish stored at − 20C.

PRACTICAL APPLICATIONS

Ribbon fish ( Trichiurus savala ) is a commercially important fish and is caught all over the state of Orissa, India. Because this fish gets spoiled fast, idea was generated in using frozen fish to produce surimi, which would increase production flexibility and thus allow a land-based surimi plant outside the harvesting season. The result of the present experiment shows that thestorage of headed and gutted ribbon fish at −20C resulted in a significant loss of gel-forming properties of the flesh with time and this loss would be too fast to allow use of storage ribbon fish for making surimi over an extended period in a commercial operation. Possibly, storage at lower temperature than used in the present study is necessary to maintain gel-forming ability and the advantage so obtained would have to be balanced against the increased capital and operational costs of storage at these lower temperatures.
