Polyurethane Tension Screens

Qhov no yog ib hom kev tshuaj ntsuam uas siv dav tshaj plaws, haum rau nruab nrab -cov ntxaij vab tshaus vibrating thiab cov ntxaij vab tshaus tas. Peb Polyurethane Tension Screens feature nias npoo los yog clamping grooves ntawm tag nrho plaub sab. Clamps, nias daim hlau, lossis cov npoo ntawm qhov screen ncej nias rau ntawm cov npoo, muab kev ruaj ntseg siab dua li cov qauv tensioned. Tsim los rau cov ntxaij vab tshaus nruab nrab nrog kev vibration acceleration ntawm 6G mus rau 8G, kev tshuaj ntsuam ntau yog 1 hli txog 60 hli, thiab qhov screen loj ntawm 2 mus rau 8 m². Dav siv nyob rau hauv mines, xuab zeb nroj tsuag, thiab thee ntxhua khaub ncaws.

Ua los ntawm ntshiab polyurethane (PU) nrog hardness ntawm 75A rau 94A (ASTM D2240), muab ob qho tib si elasticity thiab rigidity. Kev puas tsuaj tsawg dua lossis sib npaug ntawm 36 mm³ (DIN 53516). Kev ntsuas kub ntawm -35 ° C txog 100 ° C. Cov npoo nias yog txhawb zog, 30% mus rau 50% thicker tshaj qhov screen center, nrog ib tug nylon los yog steel reinforcement txheej. Flatness sib txawv ntawm ntug nias yog nyob rau hauv 0.5 hli ib 'meter', kom ntseeg tau tias nruj haum nrog lub vijtsam ncej. Lub qhov tuaj yeem yog square, round, lossis slotted, qhov loj ntawm 1 mm txog 60 mm. Qhov chaw qhib yog 28% mus rau 38%. Txhua pawg dhau 72-teev kev vibration tas li, tsis muaj npoo xoob lossis lub vijtsam txav.
