Introduction

 

Hotline thermal conductivity meter   Description:

First, sum up
the law of hot line that one kind measures the law (not a law of steady state) dynamically. Principle its to measure along sample length direction burying underground in sample centre line shape Wen Sheng for a fixed period of time of heat source. Measure the temperature of hot line and vary with time through the electric thermocouple that is welded on the mid point of hot line. Temperature of line this change to examine into material heat conduction function of coefficient. The instrument consults the standard: GB/5990-86 " fire-resistant products heat conduction coefficient test method (the law of hot line) that setting insulates against heat "; GB/T17106-1997 " refractory material heat conduction coefficient experiment method (parallel law) "; GB/T10297-1998 " determination (the law of hot line) of nonmetal solid material heat conduction coefficient ",etc.. This instrument mainly tests setting insulates against heat fire-resistant products, nonmetallic materials heat conduction coefficient at different temperature such as the material powdered. Apply to large and medium universities and colleges extensively, R&D institution, quality testing department and material for producing factory analyze that measures.
Second, main technical feature; 1, The coefficient of heat conduction tests the range: 0.015-1.7w/m• k; 2, Accuracy: ± 3%; 3, Can finish, cross line law, parallel law, realize test of controlled state to experiment temperature, test 1200 ℃ of temperature at most; 4, The sample size is required: 230*114*65(mm) ; 5, Can connect to the location machine, realize the computer tests, and realizes automatically the data are printed and exported;

 

DRX-II型導(dǎo)熱系數(shù)測定儀(熱線法)  說明:
   
     該導(dǎo)熱系數(shù)測定儀主要用于測量導(dǎo)熱系數(shù)在0.010-25W/M.K之間,溫度在1250,1400,1600℃的材料,包括定形隔熱耐火制品、氧化鎂與氧化鋁磚塊、陶瓷等非金屬材料,測試原理采用平行熱線法??捎脕頊y量各種不同類型材料的熱導(dǎo)率、熱擴散率以及熱熔,適用樣品類型:固體、粉末、顆粒狀材料。 符合GB5990-86《定形隔熱耐火制品導(dǎo)熱系數(shù)試驗方法(熱線法)》。GB/T 10297-1998《非金屬固體材料導(dǎo)熱系數(shù)的測定(熱線法)》,GB/T 17106-1997《熱耐材料導(dǎo)熱系數(shù)試驗方法(平行熱線法)》。儀器配有計算機系統(tǒng)大大簡化了操作,快速、準確。
