Taw qhia
Yog tias koj ua haujlwm nrog cov roj hmab foob, cov khoom siv yas, lossis cov khoom siv molded, koj yuav pom cov ntsiab lus zoo liNtug A 70los yogNtug Dej D 60ntawm kev kos duab. Tab sis cov lej no txhais li cas tiag? Thiab qhov tseem ceeb tshaj - qhov twg yog qhov zoo rau koj daim ntawv thov?
To taub qhov txawv ntawmShore A thiab Shore D hardness nplaiyog qhov tseem ceeb thaum xaiv cov ntaub ntawv raukev cai roj hmab sealing khoom, industrial gaskets, O-rings, thiab molded Cheebtsam.
Ntawm Xiamen Jinshun Sealing Technology Co., Ltd., peb tau tsim precision roj hmab sealing khoom txij thaum 2002. Raws li ISO 9001: 2015 tau ntawv pov thawj kev cai roj hmab sealing khoom chaw tsim tshuaj paus, hardness xaiv yog ib qho tseem ceeb tshaj plaws uas peb ntsuam xyuas thaum lub sij hawm cov khoom engineering thiab OEM / ODM kev loj hlob.
Phau ntawv qhia no piav qhia txog Shore hardness nyob rau hauv cov ntsiab lus siv tau - tsis muaj qhov nyuaj txoj kev xav, tsuas yog cov lus teb meej los pab engineers thiab pab pawg neeg yuav khoom txiav txim siab.

- Yuav Ua Li Cas Xaiv Txoj Cai Hardness rau Koj Qhov Haujlwm
Shore hardness (tseem hu ua durometer hardness) ntsuas cov khoom tsis kam rau indentation. Hauv cov ntsiab lus yooj yim, nws qhia koj tias cov khoom muag muag lossis tawv npaum li cas.
Tus lej siab dua, cov khoom siv nyuaj dua.
Qhov kev xeem yog tus qauv, tso cai rau cov tuam txhab lag luam thoob ntiaj teb los sib piv cov ntaub ntawv tsis tu ncua. Shore hardness yog qhov tseem ceeb tshwj xeeb rau:
- Roj hmab O-rings
- Silicone gaskets
- EPDM foob
- Cov vaj tse yas
- Moulded elastomer qhov chaw
Rau kev cai roj hmab sealing khoom, hardness ncaj qha cuam tshuam kev sealing kev ua tau zoo, compression set, durability, thiab hnav tsis kam.
Ib qho cuab yeej hu ua adurometerpresses ib tug hlau indenter rau hauv cov khoom nto nyob rau hauv ib tug tswj lub caij nplooj ntoos hlav quab yuam.
Tus nqi hardness nyob ntawm:
- Cov duab ntawm lub indenter
- Siv lub caij nplooj ntoos hlav quab yuam
- Qhov tob ntawm kev nkag mus
Sib txawv Shore scales siv cov kev sim sib txawv kom haum rau cov ntaub ntawv mos lossis tawv.
Shore A yog siv raucov ntaub ntawv mos thiab yoog raws, feem ntau elastomers thiab roj hmab tebchaw.
Cov yam ntxwv technical ntawm Shore A
| Parameter | Ntug A |
|---|---|
| Hom khoom | Roj hmab, elastomers, hloov tau polymers |
| Indenter Shape | Blunt 35℃cone |
| Caij nplooj ntoos hlav Force | 822 g (8.05 N) |
| Hom kab mob | 10A – 90A |
| Cov khoom siv | O-rings, gaskets, log tsheb, silicone seals |
Piv txwv Hardness References (Shore A)
| Ntug A Tus Nqi | Xav sib piv |
|---|---|
| 20A | Cov gel zoo heev -zoo li roj hmab |
| 40A | Mos roj hmab band |
| 60A | Standard automotive foob |
| 70A | Hom kev lag luam O-ring |
| 90A | Roj hmab log nyuaj |
Feem ntauroj hmab sealing khoompoob ntawm 40A thiab 80A.
Ntawm Jinshun, qhov tshwj xeeb tshaj plaws rau kev cai O-rings yog70 Nkoj A, ntsuas qhov yooj thiab sealing lub zog.
Shore D ntsuashard plastics thiab rigid polymers.
Cov yam ntxwv technical ntawm Shore D
| Parameter | Ntug Dej D |
|---|---|
| Hom khoom | Hard plastics, nruj polymers |
| Indenter Shape | Ntses 30℃cone |
| Caij nplooj ntoos hlav Force | 4536 g (44.5 N) |
| Hom kab mob | 10D – 90D |
| Cov khoom siv | Plastic vaj tse, kaus mom hlau, txiav boards |
Shore D siv zog ntau dua thiab siv lub ntsej muag ntse dua los ntsuas cov ntaub ntawv nyuaj kom raug.
| Feature | Ntug A | Ntug Dej D |
|---|---|---|
| Hom khoom | Cov roj hmab mos & elastomers | Hard plastics & rigid polymers |
| Yooj yim | Kev hloov pauv siab | Tsawg yooj |
| Indenter | Blunt | Ntsej muag |
| Caij nplooj ntoos hlav Force | qis | Siab dua |
| Tej kev siv | Cov ntsaws ruaj ruaj, gaskets, log tsheb | Cov qauv yas qhov chaw |
| Siv hauv Rubber Sealing | Yog (primary scale) | Tsis tshua muaj |
Hauv daim ntawv thov sealing, Shore A yog ntau dua. Ntug D feem ntau yog siv thaum rigidity thiab structural stability teeb meem ntau dua elasticity.
Hardness ncaj qha influences:
1. Compression Performance
Mos dhau → foob yuav extrude nyob rau hauv siab
Nyuaj dhau → tsis txaus sealing tiv thaiv mating nto
2. Hnav tsis kam
Lub hardness siab dua txhim kho kev puas tsuaj tab sis txo qhov yooj.
3. Kev ua haujlwm kub
Hardness yuav hloov nyob rau hauv huab cua kub los yog txias. Xaiv qhov sib xyaw kom raug ua kom muaj txiaj ntsig zoo ib yam.
4. Kev Pabcuam Lub Neej
Kev xaiv hardness kom zoo txo deformation, tawg, thiab to.
Piv txwv li:
Cov ntsaws ruaj ruaj feem ntau siv 60-70 Ntug A
Siab -siab hydraulic seals yuav xav tau 80–90 Shore A
Cov khoom siv kho mob silicone mos tuaj yeem siv 30-50 Shore A
Raws li kev cai roj hmab sealing khoom chaw tsim tshuaj paus, peb ib txwm pom zoo hardness raws li siab, kub, thiab tshuaj raug.
Shore A Applications
Feem ntau hauv:
- Automotive sealing systems
- Dej pom RO membrane seals
- Khoom noj khoom haus- qib silicone gaskets
- Medical elastomer Cheebtsam
- Electronic enclosure seals
Shore D Applications
Siv hauv:
- Hard yas enclosures
- Cov khoom siv tshuab ua qauv
- Lub kaus mom hlau
- Kev lag luam yas iav
Rau roj hmab O-rings, Y- seals, thiab silicone gaskets, Shore A tseem yog tus qauv.
Q1: Shore A thiab Shore D qhov tseem ceeb puas tuaj yeem sib piv ncaj qha?
Tsis yog. Lawv siv cov indenters sib txawv thiab lub caij nplooj ntoos hlav quab yuam. A 70A tsis zoo li 70D.
Q2: Dab tsi yog qhov nyuaj tshaj plaws rau O-rings?
Feem ntau cov kev lag luam O-rings siv 70 Shore A. Txawm li cas los xij, kev sib raug zoo thiab kev tshaj tawm yuav xav tau 60A lossis 90A.
Q3: Puas yog qhov nyuaj dua txhais tau tias zoo dua?
Tsis tas li. Hardness yuav tsum sib haum rau daim ntawv thov. Overly hard seals tuaj yeem xau tau yooj yim li cov muag muag heev.
Q4: Lub hardness puas tuaj yeem kho tau?
Yog lawm. Raws li kev cai roj hmab sealing khoom chaw tsim tshuaj paus, peb tsim tebchaw nyob rau hauv ib tug dav Shore A ntau yam (15A-90A).
Q5: Puas yog qhov kub thiab txias cuam tshuam rau hardness?
Yog lawm. Elastomers soften nyob rau hauv qhov kub thiab txias nyob rau hauv lub txias txias. Kev xaiv cov khoom tsim nyog them nyiaj rau tus cwj pwm no.
9. Xaus: Xaiv txoj cai Shore Hardness
Shore A thiab Shore D tsis sib tw cov nplais - lawv ua haujlwm rau cov khoom sib txawv.
Rau cov ntsaws ruaj ruaj, O-rings, silicone gaskets, thiab elastomer Cheebtsam,Ntug A feem ntau yog qhov ntsuas qhov tseeb. Shore D siv rau cov yas tsis zoo.
Xaiv qhov zoo hardness kom paub meej:
- Txhim khu kev sealing
- Extended khoom lifespan
- Txhim kho kev nyab xeeb
- Txo tus nqi tu
Hardness tsis yog tus lej ntawm daim duab xwb. Nws ncaj qha cuam tshuam cov khoom ua haujlwm.
