Problems solved by technology

[0002] The technical problem existing in the existing PE-RT floor heating pipe is that it is not suitable to measure the water temperature in the pipe, and it is impossible to accurately control the indoor temperature. At present, the temperature display system on the market is mainly an electronic digital display thermometer, which has high installation costs and low usage. Disadvantages such as inconvenient, taking up a lot of extra space (affecting the indoor appearance), and unable to display temperature after power failure

Embodiment Construction

[0020] The present invention is described in further detail below in conjunction with embodiment.

[0021] A heat-sensitive color-changing floor heating sleeve made from the following raw materials;

[0022] 1) Thermochromic masterbatch: According to the dispersion effect of green, yellow and blue thermochromic masterbatch in heat-resistant polyethylene and the temperature sensing effect of thermochromic masterbatch, weigh 0.8- 1.1kg, 0.6-0.9kg, 0.35-0.55kg of green, yellow and blue three-color raw materials, the three-color raw materials can also be taken respectively (0.8, 0.6, 0.35) ㎏ or (1.0, 0.8, 0.40) ㎏ or (1.1 . It is SHR-100A, the low speed is 430 rpm, and the high speed is 860 rpm. Since the particle sizes of the three temperature-sensitive color-changing masterbatches are basically the same, the mutual dispersibility is poor, and the grouping phenomenon is more obvious during the dispersion process, the high-low speed mixing unit can suppress the grouping of the th...

Abstract

The invention relates to a thermochomic floor heating bushing. The thermochomic floor heating bushing has different colors when the temperature changes, that is, the bushing is green when the temperature is below 21DEG C, the bushing is laurel-green when the temperature is 21-31DEG C, the bushing is yellow when the temperature is 31-43DEG C, and the bushing is white when the temperature is higher than 43DEG C. The breakthrough of the automatic identification temperature sending and display of pipelines except a digital temperature-sensitive identification system is realized by adding a thermochomic master batch in a PE-RT production formula without changing the physical or mechanical performances of original PE-RT floor heating tubes.

Description

technical field [0001] The invention relates to a thermosensitive discoloration floor heating sleeve. Background technique [0002] The technical problem existing in the existing PE-RT floor heating pipe is that it is not suitable to measure the water temperature in the pipe, and it is impossible to accurately control the indoor temperature. At present, the temperature display system on the market is mainly an electronic digital display thermometer, which has high installation costs and low usage. It is inconvenient, takes up a lot of extra space (affecting the indoor appearance), and cannot display temperature after power failure. Contents of the invention [0003] One of the objectives of the present invention is to provide a heat-sensitive color-changing floor heating sleeve with rapid temperature sensing and temperature display, no energy consumption, environmental protection, non-toxicity and good stability. [0004] The second object of the present invention is to p...
