Silicone O-ring Hardness Xaiv

Kev siv silicone O-rings plays lub luag haujlwm tseem ceeb hauv ntau qhov kev lag luam. Txawm hais tias nws yog cov khoom me me lossis cov khoom siv loj loj, silicone O-rings tsis yooj yim pom, tab sis lawv tsis tuaj yeem tsis quav ntsej. Qhov chaw plays lub luag haujlwm tseem ceeb heev.

Thaum siv silicone O-rings, vim muaj ntau hom khoom xaiv los ntawm, kev xaiv ntawm hardness yog qhov tseem ceeb heev. Piv txwv li, lub nplhaib sib khi ntawm lub twj tso kua dej twj tso kua mis hauv lub chaw nres tsheb fais fab nrog lub zog ntawm 70 (Shore) feem ntau tev tawm los yog txiav tawm tom qab. Tom qab ntawd siv lub nplhaib sib khi nrog lub hardness ntawm 85 txog 90 (Shore) thiab cov nyhuv zoo tagnrho.

Yog hais tias qhov hardness ntawm silicone O-ring tsis haum rau lub installation cheeb tsam, teeb meem yuav tshwm sim. Yog tias qhov hardness tsawg dhau, nws yuav yooj yim ua rau tev, kev puas tsuaj, extrusion thiab txawm tias tawg tawg; Yog hais tias lub hardness siab dhau lawm, installation yuav tsis yooj yim.

Feem ntau cov hardness ntawm silicone O-rings yog 40 mus rau 90 IRHD, tab sis nyob rau hauv kev siv, 60 IRHD yog feem ntau tsim nyog.

Tsuas yog los ntawm kev xaiv qhov tsim nyog silicone O-ring thiab siv nws nyob rau hauv txoj hauj lwm zoo tuaj yeem ua rau cov nyhuv ntawm silicone O-ring yuav tsum tau ua thiab xyuas kom zoo ntawm tag nrho cov khoom hauv daim ntawv thov. Qhov no kuj yog ib qho tseem ceeb shortcut rau txoj kev loj hlob rau cov lag luam. Nws tuaj yeem ua cov lus pom zoo raws li cov neeg siv khoom xav tau, uas tsis tsuas yog qhia txog kev tshaj lij, tab sis kuj muab cov lus qhia zoo rau cov neeg siv khoom.
