I-ZWS-0200 Compression Stress Relaxation Tester

Ifaneleka ngokukhethekile ucwaningo lwesicelo semikhiqizo yenjoloba njengezinto zokuvala uphawu. Ivumelana ne-GB1685 “Ukunqunywa Kwe-Compression Stress Relaxation of Vulcanized Rubber at Normal Temperature and High Temperature”, i-GB/ T 13643 “Ukunqunywa kokuphumuza ukucindezeleka kokucindezela kwerabha evuthulukile noma isampula yendandatho yerabha ye-thermoplastic” namanye amazinga. Ithuluzi lokuphumula lokucindezeleka elicindezelayo linesakhiwo esilula, ukusebenza okulula, ukuboniswa kwedijithali kwevelu yamandla acindezelayo, enembile futhi enokwethenjelwa, futhi inezinhlobonhlobo zezinhlelo zokusebenza.

Amapharamitha womkhiqizo:
1. Isilinganiso samandla enzwa/ibanga lokubonisa: 2500
2. Phoqelela ukunemba kwesilinganiso: 1% (0.5%)
3. Ukunikezwa kwamandla: AC220V±10%, 50Hz
4. Ubukhulu: 300×174×600 (mm)
5. Isisindo: cishe 35kg

Indlela yokusebenza:
1. Khetha umkhawulo ofanelekile ngokwezidingo zokuhlola bese uwulungisa ngamabhawodi ama-3.
2. Xhuma izintambo ezimbili ukusuka kuphaneli engemuva yebhokisi lesibonisi ledijithali kuya ku-indenter kanye nezikulufu zetheminali ku-backing plate. Qaphela: Ngokuvamile, lezi zintambo ezimbili akufanele zixhunywe ku-rack, inzwa, njll.
3. Vula amandla, vula inkinobho yamandla, ukukhanya kwenkomba yamandla kuvuliwe, futhi kungasetshenziswa ngemva kokufudumala imizuzu engu-5-10.
4. Uma kudingekile ukusetha kabusha, ukukhipha amandla, cindezela bese ubamba inkinobho ethi "sula".
5. Hlanza ngokucophelela indawo yokusebenza ye-fixture, bese ukhetha umkhawulo ngokuya ngohlobo lwesampula. Sebenzisa inkomba yokudayela ukuze ulinganise ubude bendawo emaphakathi yesampula. Faka isampula endaweni ukuze isampula kanye nenduku yensimbi kube ku-eksisi efanayo. I-clamp iqiniswa nge-nati ukuze iminyanise isampula kuzinga lokuminyanisa elishiwo.
6. Ngemva kwemizuzu engu-30+2, faka i-clamp ensimbini yokuphumuza, donsa isibambo ukuze uphakamise ipuleti elisusekayo, futhi i-indenter ithinta induku yensimbi, kodwa ngalesi sikhathi ingxenye eyisicaba yenduku yensimbi isathintana nengaphezulu. ipuleti lokucindezela le-clamp, futhi izintambo ezimbili zisendleleni. Isimo, ukukhanya kwenkomba yokuxhumana kuvaliwe, ipuleti eligudlukayo liyaqhubeka nokukhuphuka, isampula liyacindezelwa, ingxenye yendiza yenduku yensimbi ihlukaniswa nepuleti elicindezelayo elingaphezulu le-fixture, izintambo ezimbili zinqanyuliwe, ukukhanya kwenkomba yokuxhumana kuvuliwe, futhi inani lamandla abonisiwe liyarekhodwa ngalesi sikhathi.
7. Hambisa isibambo ukuze wehlise ipuleti elisusekayo, bese ucindezela inkinobho ethi “Zero” ukuze ukale amanye amasampuli amabili ngendlela efanayo (ngokwendinganiso.)
8. Ngemva kokuqedwa kokulinganisa, faka isampula elicindezelwe (nezinsimbi) ku-incubator yokushisa engashintshi. Uma ukusebenza kokuphumula kokucindezeleka kokucindezelwa kwesampula ku-liquid medium kukalwa, kufanele kwenziwe esitsheni esivaliwe.
9. Ngemva kokuyibeka ku-incubator isikhathi esithile, khipha into noma isitsha, uyipholise amahora angu-2, bese uyifaka kumitha yokuphumuza, futhi ulinganise amandla okucindezela esampula ngayinye ngemva kokuphumula, indlela. kuyafana no-4.6. Bala isici sokuphumula sokucindezeleka kanye namaphesenti.
10. Ngemva kokuphela kokuhlolwa, vala amandla, khipha ipulaki yamandla, futhi ugcobe isigxivizo sokuhlola, i-limiter nezinye izingxenye ngamafutha e-anti-rust ukuze ugcine.
