Thaum cov engineers qhia txog cov khoom siv roj hmab, cov lus nug feem ntau lawv nug yog: "Nws yuav nyuaj npaum li cas?" Hauv ntiaj teb kev sib khi,Hardnesstsis yog qhov kev xav tsis zoo xwb- nws yog qhov tseem ceeb ntawm kev ua haujlwm tsis zoo uas txiav txim siab seb lub kaw lus puas yuav xau lossis kav ntev.
Shore A Hardness yog dab tsi?
Hardness nyob rau hauv elastomers feem ntau yog ntsuas nyob rau hauvNtug A scalesiv lub tshuab hu ua durometer. Kev ntsuas ntsuas qhov tsis kam ntawm cov roj hmab mus rau qhov indentation ntawm tus qauv steel koob.
Qhov ntsuas qhov sib txawv ntawm 0 mus rau 100. Rau kev ua lag luam sealing, feem ntau koj yuav ntsib cov ntaub ntawv ntawm40 (mos zoo li mem hluav lwv)thiab90 (nyuaj zoo li lub pob bowling). Cov qauv kev lag luam rau feem ntau O-rings thiab gaskets yog70 Nkoj A, muab kev sib npaug sib npaug ntawm kev hloov pauv thiab lub zog.
Kev Lag Luam Kev Lag Luam - tawm: Soft vs. Hard
Xaiv qhov tseeb hardness yog qhov sib npaug me me. Yog tias koj xaiv tsis raug, koj yuav muaj kev pheej hmoo ntawm kev sib khi tsis zoo ntawm qhov tsis tshua muaj siab lossis muaj kev puas tsuaj loj ntawm kev kub ntxhov.
- Softer Materials (40-60 Ntug A):Cov no yoog tau yooj yim dua rau cov hlau tsis sib xws. Lawv yuav tsum tau qis compression quab yuam los tsim ib lub foob, ua rau lawv zoo tagnrho rau cov mos yas vaj tse los yog tsawg- daim ntawv thov siab.
- Cov ntaub ntawv nyuaj (80-90 Ntug A):Cov no muab superiorExtrusion Resistance. Nyob rau hauv siab - hydraulic tshuab, lub foob mos yuav "squeezed" rau hauv cov khoom kho vajtse tshem tawm qhov khoob zoo li cov tshuaj txhuam hniav, ua rau nws tawg. Cov ntaub ntawv nyuaj dua no deformation.
Hardness thiab Dynamic Friction
Hauv daim ntawv thov dynamic (qhov twg lub foob txav tawm ntawm lub ncej), hardness cuam tshuam rau "kev sib txhuam tawm." Softer seals muaj thaj tsam loj dua, uas tuaj yeem ua rau muaj kev sib txhuam thiab hnav. Cov ntsaws ruaj ruaj muaj qhov sib tiv me me, muaj peev xwm txo tau kev sib txhuam tab sis yuav tsum tau ua kom zoo dua qhov saum npoo ntawm cov khoom siv hlau los tiv thaiv kev xau.
📐 Precision Hardness rau koj daim ntawv thov:Peb muab 100% durometer pov thawj ntawm tag nrho cov khoom tseem ceeb. Tshawb xyuas peb cov kev xaiv khoom:
- Kev cai Moulded Elastomer Parts: Muaj nyob rau hauv tag nrho cov hardness ntawm 30 txog 95 Shore A.
- Precision Rubber Balls: Optimized hardness rau check-valve thiab tu daim ntawv thov.
Qhov tseem ceeb ntawm Kev Ntsuas Kev Ntsuas
Nws yog ib qho tseem ceeb kom nco ntsoov tias roj hmab hardness tsis tshua muaj ib tus lej. Kev lag luam tus qauv kam rau ua yog feem ntau+/- 5 cov ntsiab lus. Kub kuj plays lub luag hauj lwm; roj hmab yuav nyuaj dua thaum nws tau txias thiab softer thaum nws heats. batch zoo ib yam-rau-batch hardness yog lub cim ntawm lub siab- cov chaw tsim khoom zoo xws li Xiamen Best Seal.
