岩棉复合板出产线是把彩涂钢卷压成型后用强力粘合剂复合在较厚的内芯资料的两面,形成了一种强度高、分量轻、隔热保温、坚固耐用外形美丽的新式修建资料。降解功能及其点评

The production line of rock wool composite board is a new type of construction material with high strength, light weight, heat insulation, durability and beautiful appearance, which is made of color-coated steel coiled and formed with strong binder on both sides of thicker inner core data. Degradation Function and Its Comments
对生物降解资料的降解功能的测验现在还没有制定统一的标准,可采用包括被美国资料实验标准(ASTM)采用或预备采用的办法作为标准的办法,通过生物化学和微生物的实验手段来点评的主要办法有下列几种。
There is no unified standard for testing the degradation function of biodegradable data. The methods adopted or prepared by ASTM can be used as the standard. The main methods for evaluating the degradation function of biodegradable data by biochemical and microbiological methods are as follows.
土埋法
Soil burying method
土埋法有室外土埋法和室内土埋法两种,其微生物源主要是土壤中的微生物群,经必定时刻后,取出试样测定其失重、机械功能改变,或用电子显微镜确定其被土壤中微生物侵袭的状况。长处是能反映出自然环境条件下的生物分化功能;缺陷是实验周期长,实验结果因土质不同而不同,重复性差。
There are two kinds of soil burial methods: outdoor soil burial method and indoor soil burial method. The microbial source is mainly the microbial community in soil. After a certain time, the samples are taken out to determine their weight loss, mechanical function changes, or the microbial invasion status in soil is determined by electron microscopy. The advantage is that it can reflect the biological differentiation function under natural environment conditions; the defect is that the experimental period is long, the experimental results vary according to the soil quality, and the repeatability is poor.
陪替氏培育器定量法
Quantitative method of Petit's incubator
在容器中参加实验样品和营养琼脂,接种微生物进行培育,经必定时刻后,剖析试样的失重状况以及某些物理改变或化学改变。长处是可快速降解,在短时刻内获得实验结果,重复性好,定量性好;缺陷是不能反映自然界中的实际状况。
Participate in the experimental samples and nutrient agar in the container, inoculate microorganisms for cultivation, after a certain time, analyze the weight loss of samples and some physical or chemical changes. The advantage is that it can be degraded quickly and the experimental results can be obtained in a short time with good repeatability and quantification. The defect is that it can not reflect the actual situation in nature.
酶剖析法
Enzyme analysis
在容器中参加缓冲液和实验样品,让酶效果必定的时刻后,剖析试样的失重状况,目测霉菌的成长状况,显微镜剖析试样物理功能或化学功能的改变。长处是实验周期短,重复性好,定量性好;缺陷是不能反映自然界中的实际状况。
When the buffer solution and the experimental sample are added in the container, the weight loss of the sample is analyzed, the growth of the mould is observed, and the changes of the physical or chemical functions of the sample are analyzed under the microscope. The advantage is that the experiment cycle is short, the repeatability is good, and the quantity is good. The defect is that it can not reflect the actual situation in nature.
放射性C14示踪法
Radioactive C14 tracer method
用C14标记聚合物产品,在微生物的效果下发生CO2,用碱性溶液吸收,用滴定法测出CO2总量,再用放射性衰减率法测定C14的CO2量,用C14的CO2占发生的CO2的百分数表明微生物侵蚀的程度。长处是实验结果牢靠、明确。生物降解功能的测验能够检测样品生物降解功能的好坏。
Using C14 labeled polymer products, carbon dioxide occurs under the effect of microorganisms, is absorbed by alkaline solution, the total amount of carbon dioxide is measured by titration, and then the amount of carbon dioxide in C14 is determined by radioactivity attenuation rate. The percentage of carbon dioxide in C14 is used to indicate the degree of microbial erosion. The advantage is that the experimental results are reliable and clear. The biodegradability test can detect the biodegradability of samples.
