Takeaway pawimawh tak tak:

1. Acid environment = Polyester —nylon hi acid hian a tichhia a

2. Alkali environment = Nylon —polyester hi alkali hian a tichhia a

3. Precision lifts = Polyester —elongation hniam chuan control a pe a

4. Dynamic loads = Nylon —stretch sang zawk hian shock a absorb thin

5. Outdoor/wet = Polyester —UV laka invenna leh tuikhuah laka invenna

6. Blue line chu enfiah rawh —polyester slings hian tracer line blue a nei a; nylon chuan a ti lo

7. Tag chu verify fo rawh —ASME B30.9 hian sling tag-a material identification a mamawh a ni

Lishenflex hian EN 1492-1 leh ASME B30.9 standard angin polyester leh nylon flat sling pahnih a siam a, material identification chiang tak leh color-coded capacity marking a nei bawk. I chemical environment bik leh application mamawh dan azirin material thlan dan tur kaihhruaina kan pe thin.
