DIN vs Akron vs NBS vs Taber: Me pēhea te whiriwhiri i te paerewa whakamātautau mō te whakakoi rapa

Ngā Mīhini Whakamātautau: UP-1008 DIN Abrasion Tester, UP-1001 Akron Abrasion Tester, UP-1009 NBS Abrasion Tester, UP-1010 Taber Abrasion

Paerewa Kaiwhakamātautau: DIN 53516 / ISO 4649 / ASTM D1630 / ASTM D4060 Ngā Whakamahinga: Rapa, kapu hū, potae me ngā rauemi rapa

He mea nui te whakamātautau pakū hei aromatawai i te ātete kakahu o ngā rauemi rapa. Ko te DIN, ko Akron, ko NBS me ko Taber ngā tikanga whakamātautau pakū e whā e whakamahia whānuitia ana, he motuhake ngā mātāpono me ngā tono e tika ana mō ia tikanga.

DIN Abrasion (DIN 53516 / ISO 4649)Ka mirimiri tētahi tauira porotaka ki tētahi pahu kirikiri hurihuri. Ka inehia te hua mā te ngaronga rōrahi (mm³).

✅ Te mōhiotanga ā-ao, te rahi tauira iti me te whakamātautau tere

✅ He pai mō te R&D matū rapa, ngā kapu rapa, te rapa takahanga me ngā elastomers whānui

❌ Kāore i te tūtohutia mō ngā paninga mārō, ngā kiri angiangi me ngā tauira tauira nui

Te Whakakorenga o Akron (ASTM D1630)Ka mahi te tauira wira rapa whakarara i te waku hurihuri-paheke ki te wira huri hei whakatauira i te pakaru o ngā potae. Ka tuhia ngā hua hei whakahekenga taumaha mō ia 1000 hurihanga.

✅ Ka whakatauira i ngā āhuatanga hurihuri tūturu o ngā potae

✅ He pai mō ngā takahanga potae me ngā roera rapa taumaha

❌ Kāore i te tūtohutia mō ngā rau rapa angiangi me te rapa pahuka ngohengohe

Te Whakakorenga NBSKa pēhia he tauira poraka ki runga i tētahi wira huri hurihuri hei whakamātautau i te kākahu reti reti ahotea teitei.

✅ He iti te utu, he pai mō te whakataurite ā-roto i ngā rauemi hu

✅ He pai mō ngā kapu rapa mārō, me ngā taputapu QC hou mai i te wheketere

❌ Kāore e taea te whakahoki anō; kāore e pai mō te rapa ngohengohe iti-tauwehenga me te aromatawai tātai tika

Te Whakakorenga Taber (ASTM D4060)Ka whakapūmauhia he tauira papatahi, ā, ka hangaia e ngā wira hurihuri takirua ngā ara pakaru porowhita. Ka inehia te whakahekenga taumaha. Ka tautokona ngā rauemi maha. ✅ He maha ngā whakamahinga mō te rapa, te kirihou, ngā paninga me te hiako me ngā wira ka taea te whakawhiti.

✅ He pai mō ngā pepa rapa, ngā paninga rapa me ngā panera hiato

❌ Kāore i te tūtohutia mō te rapa ngohengohe tino ngāwari, ngā tauira piko me ngā matū potae (ka ngāwari te hurihanga me te hanga wera)

Whakatau Kōwhiringa

• Taia potae / roera rapa taumaha →Ākerona(ASTM D1630)
• Pūhui rapa / kapu rapa / elastomer whānui →DIN(ISO 4649 / DIN 53516) [E taunakitia ana]
• He kapu rapa mārō, he māmā noa te tirotiro →NBS
• Pepa rapa papatahi / paninga / hiato, whakamātautau maha-rauemi →Tāpa(ASTM D4060)
• Rapa pahuka ngohengohe / kiri rapa angiangi → He pai ake te DIN, karohia te Taber
