DRK135 Falling Dart Impact Tester

The DRK135 falling dart impact tester imagwiritsidwa ntchito kudziwa kuchuluka kwa mphamvu ndi mphamvu ya 50% ya filimu yapulasitiki kapena ma flakes mothandizidwa ndi kutalika kwa mivi yogwera yaulere yokhala ndi makulidwe osakwana 1mm.

Mayeso otsitsa dart nthawi zambiri amasankha njira yoti achite, ndipo njira yoyambira imagawidwa mu njira ya dontho la dart A ndi njira ya B.

Kusiyanitsa pakati pa ziwirizi: kutalika kwa mutu wa dart, zakuthupi ndi kutalika kwa dontho ndizosiyana. Nthawi zambiri, Njira A ndi yoyenera pazida zokhala ndi 50g ~ 2000g. Njira B ndi yoyenera pazida zokhala ndi kuwonongeka kwakukulu kwa 300g mpaka 2000g.
Pakati pawo, njira ya cascade ya GB/T 9639 ndi ISO 7765 ndi njira zofanana.
Njira A: Kutalika kwa mutu wa dart ndi 38 ± 1mm. Zida za mutu wa dart zimapangidwa ndi aluminiyamu yosalala komanso yopukutidwa, pulasitiki ya phenolic kapena zinthu zina zotsika kwambiri zolimba zolimba. Kutalika kwa dontho ndi 0.66±0.01m.
Njira B: Kutalika kwa mutu wadart wogwa ndi 50 ± 1mm. Zida za mutu wa dart zimapangidwa ndi chitsulo chosapanga dzimbiri chosalala, chopukutidwa kapena zinthu zina zolimba zofanana. Kutalika kotsika ndi 1.50 ± 0.01m. Mu ASTM D1709, kutalika kwa mutu wa dart wa njira A ndi njira B ndi 38.1±0.13mm ndi 50.8±0.13mm, motsatana.

Mawonekedwe

1. Chitsanzo cha makina ndi chatsopano, kamangidwe kake kameneka kamakhala koganizira, ndipo miyezo ya dziko ndi mayiko akunja zimagwirizana nthawi imodzi.
2. Njira yoyesera A, B wapawiri mode.
3. Data yoyesera Njira yoyesera ndi yanzeru, yomwe imapangitsa kuti ntchito ikhale yabwino kwambiri.
4. Chitsanzocho chikumangidwa pneumatically ndikumasulidwa, zomwe zimachepetsa kulakwitsa koyesera ndi nthawi yoyesera.
5. Data chizindikiro dongosolo LCD anasonyeza.

Mapulogalamu

Mafilimu ndi mapepala ndi oyenera kuyesa kukana kwa mafilimu apulasitiki, mapepala ndi mafilimu ophatikizika okhala ndi makulidwe osakwana 1mm. Monga filimu yophika ya PE, filimu yotambasula, pepala la PET, matumba onyamula zakudya amitundu yosiyanasiyana, matumba onyamula katundu ndi zojambula zina zotayidwa, filimu yopangidwa ndi aluminium-pulasitiki, yoyenera kuyesa kukana kwa zojambulazo za aluminium, filimu yopangidwa ndi aluminium-pulasitiki, pepala, mayeso a makatoni Amagwiritsidwa ntchito poyesa kukana kwa pepala ndi makatoni.
luso muyezo. Kumayambiriro kwa mayesero, choyamba sankhani njira yoyesera, yerekezerani misa yoyamba ndi Δm mtengo, ndikuyesa. Ngati chitsanzo choyamba chathyoledwa, gwiritsani ntchito kulemera kwa Δm kuchepetsa kugwa kwa thupi; ngati chitsanzo choyamba sichikusweka, gwiritsani ntchito kulemera kwa Δm kuti muwonjezere Ubwino wa thupi lakugwa umayesedwa moyenerera. Mwachidule, kugwiritsa ntchito zolemera kuti kuchepetsa kapena kuonjezera kuchuluka kwa thupi lakugwa kumadalira ngati chitsanzo chapitacho chawonongeka. Pambuyo pa zitsanzo za 20 zoyesedwa, werengerani chiwerengero chonse cha kuwonongeka N. Ngati N ndi yofanana ndi 10, mayeserowo atha; ngati N ili yochepera 10, mutatha kubwezeretsanso chitsanzocho, pitirizani kuyesa mpaka N ikufanana ndi 10; ngati N ndi yaikulu kuposa 10, mutatha kubwezeretsanso chitsanzocho, pitirizani kuyesa mpaka Chiwerengero chonse cha osawonongeka chikufanana ndi 10, ndipo pamapeto pake zotsatira zake zimawerengedwa zokha ndi dongosolo. Chidachi chikugwirizana ndi GB9639, ASTM D1709, JISK7124 ndi miyezo ndi malamulo ena oyenera.
