Meta tiwweldja ġeomembrani, kif tikkontrolla t-temperatura biex tiżgura li ma jkunx hemm lakuni

Qabel l-iwweldjar tal-ġeomembrana, il-ġeomembrana hija maqtugħa, allinjata, imnaddfa (immesaħ bit-trab) u ttestjata qabel l-iwweldjar. TH-2 tip mulch film tal-magna tal-welding hija adottata
35mm, wisa 'tal-ġonta tal-istann wieħed l Omm. Wara li jitlesta l-iwweldjar, jitkessaħ u jissolidifika għal 20 minuta. Iż-żewġt itruf tal-weldjatura huma mblukkati b'torċi tal-iwweldjar tal-plastik DSH-II, u l-labra tas-sejbien tal-inflazzjoni tintuża għall-iskoperta tal-inflazzjoni.
Twettqu total ta '4 gruppi ta' testijiet tal-iwweldjar, u l-veloċità tal-magna tal-iwweldjar kienet 2.1, 2.5 u 3 rispettivament. 0,3. 2 m/min. It-temperatura tal-iwweldjar hija 300, 3600C. Temperatura ambjentali 24 grad - 270ċ, anemometru portabbli bi tliet tazzi DEM6, kontroll tal-veloċità tar-riħ<2m/s, welding pressure can not be displayed, no adjustment. The working conditions of the weld and the welding machine under the above environmental conditions were tested by aeration method, and the test results were qualified. According to the construction site situation and other factors, it is recommended to control it at 2. 0}3. When the wind speed is less than 2m/s and the ambient temperature is 24 ~ 300 °C, the welding temperature is between 300 ~ 360 °C.
