Roj hmab hardness, ntsuas los ntawm Shore A nplai, plays lub luag hauj lwm txiav txim siab nyob rau hauv sealing kev ua tau zoo.Xaiv qhov raug Shore A hardness ncaj qha cuam tshuam rau tus cwj pwm compression, tiv thaiv cov dej xau, kev pab lub neej, thiab tag nrho cov sealing ntseeg tau.
Hauv tsab xov xwm no, peb piav qhia yuav ua li cas sib txawv Shore A hardness qib cuam tshuam cov roj hmab foob thiab yuav ua li cas xaiv qhov zoo tshaj plaws hardness rau cov khoom sib khi.
Nkag siab Shore A Hardness hauv Rubber Seals
Shore A hardness ntsuas cov khoom siv roj hmab tsis kam rau indentation. Rau kev sib khi daim ntaub ntawv, cov hardness feem ntau yog los ntawm 20 Shore A (mos) txog 90 Ntug A (nyuaj).
Feem ntau cov khoom siv roj hmab sealing-xws liroj hmab O-rings, roj hmab gaskets, thiabroj hmab hoses- cia siab rau kev xaiv hardness kom ua tau zoo sealing.
Shore A Hardness cuam tshuam rau Sealing Performance

Soft Rubber Seals (30–40 Ntug A)Soft Shore A roj hmab muab kev sib khi zoo heev ntawm qhov tsis tshua muaj siab thiab qhov tsis sib xws vim qhov ua tau zoo ntawm qhov chaw.
Feem ntau hauv cov roj hmab gaskets thiab qis - cov ntawv thov kev sib khi. |
Medium Hardness Roj Hmab (60-70 Ntug A)Medium Shore A roj hmab muaj qhov sib npaug zoo ntawm elasticity thiab txhua yam muaj zog, ua rau nws feem ntau siv hardness ntau rau kev siv sealing.
Cov ntawv thov ib txwm suav nrogroj hmab foob ringsthiab molded roj hmab foob. |

High Hardness Roj Hmab (80-90 Ntug A)High Shore A cov ntaub ntawv roj hmab yog tsim los rau cov ntawv thov uas qhov kev ua haujlwm siab thiab qhov ruaj khov yog qhov tseem ceeb.
High- roj hmab hardness feem ntau yog siv rau hauv cov roj hmab hoses, thaub qab rings, thiab hnyav -lub luag hauj lwm muaj sealing tshuab. |
Yuav Ua Li Cas Xaiv Txoj Cai Shore A Hardness
Thaum xaiv cov roj hmab hardness rau cov khoom sib khi, xav txog cov ntsiab lus tseem ceeb no:
- Ua haujlwm siab:Siab siab yuav tsum siab dua Shore A hardness
- Deg mob:Rough nto xav tau cov roj hmab softer
- Dynamic zog:Nruab nrab hardness yog nyiam rau txav cov ntsaws ruaj ruaj
- Media thiab kub:Yam khoom thiab hardness yuav tsum ua hauj lwm ua ke
Qhov Zoo Tshaj Plawsmuaj kev kho cov roj hmab sealing kev daws teeb meem nrog Shore A hardness xws li 20 txog 90, haum rau cov ntawv thov tshwj xeeb.
Hom Shore A Hardness rau cov khoom siv
| Yam khoom | Pom zoo Shore A | Daim ntawv thov tseem ceeb |
|---|---|---|
| Roj Hmab O-Rings | 60–70 | Hydraulic & pneumatic sealing |
| Roj Hmab Gaskets | 30–60 | Static flange sealing |
| Roj Hmab Hoses | 65–90 | Kev hloov pauv dej thiab siab |
| Moulded Rubber Parts | 50–80 | Kev cai sealing kev daws teeb meem |
