Ramie Ramie 2009, the quality of existing problems and countermeasures – pneumat
Hemp fiber in order to protect our resources, maintaining the economic interests of both transactions, conduct and regulate market order hemp fiber, hemp fiber distribution system for the Chinese Fiber Inspection Bureau in June 2005 from the Hunan province as a public review of Ramie Ramie one of the pilot on ramie fiber products manufacturer to be purchased by Ramie Ramie implementation of inspector, notary test results as a trading settlement price both quality and quantity of the evidence.
I assume the Hunan Huasheng Board Cedar Co., Ltd. Zhuzhou, Hunan, Guangyuan Ma Industry Co., Ltd., Hunan compete in Ramie Textile Co., Ltd., Hanson County, Ziyang Textiles Co., Ltd., Ma Yuanjiang City Star Ramie Industry Co., Ltd. A total of five lean Ma tasks using enterprise inspector, through the years 2008 and 2009 Ramie Ramie inspector to compare the results on our province now that five public companies use Ramie Ramie review existing quality of analysis for one.
Ramie Ramie basic conditions of quality problems
1.2009 and 2008 compared to the total weight of the test batch and the test is insignificant, but the overall level of contracting out the number in 2009 than in 2008, an increase of 52 lots, the overall level higher proportion occurred outside the batch was 19.85 %.
2.2009 and 2008 compared to ramie Ramie of the technical indicators mean the difference between the total is greater fiber bundle strength and the residual gum. Bundle fiber strength: in 2009 than in 2008, down 0.73cN/dtex, lower the level of total level; residual gum: 2009 lower than 0.63% in 2008, the total level of high level.
3.2009 and 2008 compared to ramie Ramie inspector approved all other times the difference between the percentage is not. First slightly higher proportion in 2009 was 2.64%, but the level of contracting out the percentage of the number of 2009 high of 19.85%, primary and secondary Ramie Ramie batch number and percentage of all to 0.
4.2009 and 2008, compared to the technical indicators / level of contracting the percentage difference between the number of large oil content followed, pH, bundle fiber strength, were higher by 22.6%, 13.8%, 10.6 %; a consistent rate and the rate of 90% second line of the batch number is 0, the number three line rates approved for 2008 and 2009 the percentage difference between the smaller, respectively, 88.4% and 88.1%.
Causes of decline in the quality
1. Bundle fiber strength the main reason: The first hemp degumming process parameters, and the incorrect conditions (such as time, temperature and acid / base concentration), resulting fibers are injured, resulting in decreased strength; Second, the original Ma in the biological degumming of the fermentation process, susceptible to bacteria contamination, resulting in cellulase, to decrease breaking strength of fiber bundles; 3 is due to poor quality of raw jute, hemp shell too much, resulting in increased business in the degumming acid concentration, extended pickling and alkali cooking time, increase the frequency of copy Ma resulted in decreased fiber strength.
2. Oil content level of contracting out have increased the percentage of the number of main reasons: First, as strict process control to oil; Second, as most of the oil from hemp business elite to a mixture of vegetable oil or new oil oil (new oil to the oil with fast, efficient, low consumption, energy saving, suitable for the characteristics at room temperature for oil), but by now the national standard test method standards required for detection, oil content results are mostly in range of 0.2% ~ 0.5% difficult to reach the current national standards.
3.pH value level of contracting the percentage increase in the number of main reasons: First, wash often enough, not completely wash away the fibers of the acid, lye, and second, after dipping as degumming without acid treatment, resulting in pH values high; 3 is due by the biological degummed ramie Ramie alkaline than acidic when the powerful force when the slightly higher, so companies are not too large in order to maintain fiber strength damage, often alkaline control.
4. A consistent rate and the secondary line 90% of the approved rate of the number in 2008 and 2009 are 0, indicating the test batch Ramie Ramie not meet quality standards in the appearance of one or two requirements. Main reasons: First, in recent years, ramie weak sales market, the enthusiasm of farmers to plant hemp setback, coupled with inefficient manual stripping hemp, making harvest greatly extended, resulting in the quality of the original Ma compared with earlier years decreased; 2 Most of the enterprises in our province is ramie degumming technology is not yet mature, resulting in inconsistent quality lean anesthesia, not to mention the high quality appearance, eventually leading to crack the overall quality of anesthesia at lower levels.
