DIN vs Akron vs NBS vs Taber: Momwe Mungasankhire Muyezo Woyesera wa Rubber Abrasion

Makina Oyesera: Choyesera cha UP-1008 DIN Abrasion, Choyesa cha UP-1001 Akron Abrasion, Choyesa cha UP-1009 NBS Abrasion, Choyesa cha UP-1010 Taber Abrasion

Miyezo Yoyesera: DIN 53516 / ISO 4649 / ASTM D1630 / ASTM D4060 Ntchito: Rabala, nsapato, matayala ndi zipangizo zotanuka

Kuyesa kwa abrasion ndikofunikira kuti muwone ngati zipangizo za rabara sizikutha. DIN, Akron, NBS ndi Taber ndi njira zinayi zoyesera abrasion zomwe zimagwiritsidwa ntchito kwambiri, iliyonse ili ndi mfundo zapadera komanso kugwiritsa ntchito koyenera.

DIN Abrasion (DIN 53516 / ISO 4649)Chitsanzo chozungulira chimakanda pa ng'oma ya sandpaper yozungulira. Zotsatira zake zimayesedwa ndi kutayika kwa voliyumu (mm³).

✅ Kuzindikirika padziko lonse lapansi, kukula kochepa kwa zitsanzo komanso kuyesa mwachangu

✅ Yabwino kwambiri pa kafukufuku ndi chitukuko cha rabara, zofunda za rabara, rabara yonyamulidwa ndi ma elastomer ambiri

❌ Sikoyenera kugwiritsa ntchito zophimba zolimba, zikopa zoonda komanso zitsanzo zazikulu zokhala ndi mapatani

Kutupa kwa Akron (ASTM D1630)Chitsanzo cha gudumu la rabara lopendekeka chimachita kukangana kozungulira motsutsana ndi gudumu lopukusira kuti chiyerekezere kuwonongeka kwa tayala. Zotsatira zake zimalembedwa ngati kuchepetsa thupi pa 1000 revolutions.

✅ Imatsanzira momwe matayala amayendera

✅ Yabwino kwambiri pa matayala ndi ma roller a rabara olemera

❌ Sikoyenera kugwiritsa ntchito mapepala a rabara owonda komanso rabara yofewa ya thovu

Kuphulika kwa NBSChitsanzo cha buloko chimakanikizidwa pa gudumu lopukutira lozungulira kuti chiyesedwe kuti chikhale chotsika kwambiri.

✅ Mtengo wotsika, woyenera kufananiza mkati mwa nsapato

✅ Yabwino kwambiri pazitsulo zolimba za rabara komanso QC yomwe ikubwera ku fakitale

❌ Kusabwerezabwereza bwino; sikuli koyenera kuyesedwa bwino ndi rabara yofewa yokhala ndi modulus yochepa

Kutupa kwa Taber (ASTM D4060)Chitsanzo chosalala chimakhazikika, pomwe mawilo awiri ozungulira ozungulira amapanga njira zozungulira zotayirira. Kuchepetsa thupi kumayesedwa. Chimathandizira zinthu zosiyanasiyana. ✅ Chimagwiritsidwa ntchito popanga rabara, pulasitiki, zokutira ndi chikopa chokhala ndi mawilo osinthika

✅ Zabwino kwambiri pa mapepala a rabara, zokutira za rabara ndi mapanelo ophatikizika

❌ Sikoyenera kugwiritsa ntchito pa mphira wofewa wotanuka kwambiri, zitsanzo zokhota komanso zinthu zina zophatikizana ndi matayala (zomwe zimatha kusintha mawonekedwe ndi kutentha kwambiri)

Chisankho Chosankha

• Chopondera matayala / chopukutira cha rabara cholemera →Akron(ASTM D1630)
• Rabala lopangidwa / chidendene cha rabala / elastomer wamba →DIN(ISO 4649 / DIN 53516) [Yolangizidwa]
• Chidendene cholimba cha rabara, kuyang'ana kosavuta kolowera →NBS
• Pepala lathyathyathya la rabara / chophimba / chophatikizika, mayeso azinthu zambiri →Taber(ASTM D4060)
• Rabala yofewa ya thovu / khungu lopyapyala la rabala → DIN ndi yabwino, pewani Taber
