Cov yam ntxwv yooj yim thiab cov haujlwm tseem ceeb ntawm ob -Cov khoom siv Silicone Sealant

Ob -cov khoom siv silicone sealant yog sib xyaw ntawm cov khoom A (cov nplaum nplaum) thiab cov khoom B (kho tus neeg sawv cev) uas kho tom qab sib tov. Nws cov haujlwm tseem ceeb tuaj yeem raug sau tseg raws li hauv qab no:

1. High-Lub zog Bonding: Bond lub zog rau cov ntaub ntawv xws li iav, hlau, thiab pob zeb tuaj yeem ncav cuag 1.5-2.5 MPa (raws li GB/T 14683-2017), deb tshaj li 0.8-1.2 MPa ntawm cov khoom siv ib leeg, ua rau nws tsim nyog rau kev sib koom ua ke.

2. Kev ruaj ntseg nyob rau hauv ib puag ncig huab cua: Nrog rau qhov kub ntawm -60℃mus rau 200℃thiab lub neej kev pab ntau tshaj 20 xyoo nyob rau hauv UV raug (ASTM C794 cov ntaub ntawv xeem), nws yog haum rau daim ntaub ntawv xws li sab nraum zoov kab hlau rhuav phab ntsa thiab choj expansion pob qij txha.

3. Dynamic Displacement Compensation: Nrog ib qho elastic rov qab tus nqi siab dua los yog sib npaug li 90% (ISO 9047 tus qauv), nws tuaj yeem tiv taus ± 50% kev sib koom ua ke, hais txog kev tawg los ntawm thermal expansion thiab contraction hauv cov tsev.

4. Tshuaj tiv thaiv inertness: Resistant rau acid, alkali thiab ntsev tsuag corrosion, feem ntau yog siv rau pipeline sealing nyob rau hauv tshuaj nroj tsuag los yog kev tiv thaiv ntawm marine khoom.
