I-DRK135 I-Falling Dart Impact Tester

Isihloli somthelela we-DRK135 esiwayo sisetshenziselwa ukunquma isisindo somthelela namandla angu-50% wefilimu yepulasitiki noma ama-flakes ngaphansi komthelela wobude obunikeziwe bemicibisholo ewa mahhala enogqinsi olungaphansi kuka-1mm.

Ukuhlolwa kokuwa kwe-dart kuvame ukukhetha indlela yesinyathelo okufanele yenziwe, futhi indlela yesinyathelo ihlukaniswa ngendlela ye-dart drop impact A kanye nendlela engu-B.

Umehluko phakathi kwalokhu okubili: ububanzi bekhanda le-dart, impahla kanye nokuphakama kokudonsa kuhlukile. Ngokuvamile, Indlela A ifanele izinto ezinomonakalo wesisindo esingu-50g～2000g. Indlela B ifanele izinto ezinomthelela wesisindo esingama-300g kuya ku-2000g.
Phakathi kwazo, indlela ye-cascade ye-GB/T 9639 ne-ISO 7765 yizindlela ezilinganayo.
Indlela A: Ububanzi bekhanda lomcibisholo ngu-38±1mm. Impahla yekhanda le-dart yenziwe nge-aluminium ebushelelezi nephucuziwe, ipulasitiki ye-phenolic noma ezinye izinto ezisezingeni eliphansi ezinobunzima obufanayo. Ukuphakama kokwehla kungu-0.66±0.01m.
Indlela B: Ububanzi bekhanda lomcibisholo eliwayo ngu-50±1mm. Impahla yekhanda lomcibisholo yenziwe ngensimbi engenasici ebushelelezi, epholishiwe noma ezinye izinto ezinobulukhuni obufanayo. Ukuphakama okuwayo kungu-1.50 ±0.01m. Ku-ASTM D1709, ububanzi bekhanda lomcibisholo wendlela A nendlela B ingu-38.1±0.13mm kanye no-50.8±0.13mm, ngokulandelana.

Izici

1. Imodeli yomshini iyinoveli, umklamo wokusebenza uyacabangela, futhi izindinganiso zikazwelonke nezindinganiso zamazwe ngamazwe ziyahambisana ngesikhathi esifanayo.
2. Indlela yokuhlola A, B imodi ekabili.
3. Idatha yokuhlola Inqubo yokuhlola ihlakaniphile, ethuthukisa kakhulu ukusebenza kahle komsebenzi.
4. Isampula iqiniswa ngokomoya futhi yakhululwa, okunciphisa iphutha lokuhlola nesikhathi sokuhlola.
5. Isibonisi se-LCD sepharamitha yedatha.

Izinhlelo zokusebenza

Amafilimu namashidi afanele ukuhlolwa kokumelana nomthelela wamafilimu epulasitiki, amashidi namafilimu ayinhlanganisela anogqinsi olungaphansi kuka-1mm. Njengefilimu yokunamathela ye-PE, ifilimu elula, ishidi le-PET, izikhwama zokupakisha zokudla zezakhiwo ezihlukahlukene, izikhwama ezisindayo zokupakisha nezinye i-aluminium foil, ifilimu eyinhlanganisela ye-aluminium-plastic, efanelekile ukuhlolwa kokumelana nomthelela we-aluminium foil, ifilimu eyinhlanganisela ye-aluminium-plastic, iphepha, ukuhlolwa kwekhadibhodi Isetshenziselwa ukuhlola ukumelana nomthelela wephepha nekhadibhodi.
izinga lobuchwepheshe. Ekuqaleni kokuhlolwa, qala ngokukhetha indlela yokuhlola, linganisela isisindo sokuqala kanye nevelu engu-Δm, bese wenza ukuhlola. Uma isampula yokuqala iphukile, sebenzisa isisindo Δm ukunciphisa isisindo somzimba esiwayo; uma isampula yokuqala ingaphukile, sebenzisa isisindo Δm ukwandisa Ikhwalithi yomzimba owelayo ihlolwe ngokufanele. Ngamafuphi, ukusetshenziswa kwezisindo ukunciphisa noma ukwandisa isisindo somzimba owelayo kuncike ekutheni isampula yangaphambilini yonakalisiwe. Ngemva kokuhlolwa kwezibonelo ezingu-20, bala inani eliphelele lomonakalo N. Uma i-N ilingana no-10, ukuhlolwa kuqediwe; uma u-N engaphansi kuka-10, ngemva kokugcwalisa isifanekiso, qhubeka nokuhlola kuze kufike u-N elingana no-10; uma i-N ingaphezu kuka-10, ngemva kokugcwalisa isifanekiso, qhubeka nokuhlola kuze kube Ingqikithi yenani labangalimele lilingana no-10, futhi ekugcineni umphumela womthelela ubalwa ngokuzenzakalelayo uhlelo. Ithuluzi lihambisana ne-GB9639, ASTM D1709, JISK7124 namanye amazinga nemithethonqubo efanele.

Ipharamitha yomkhiqizo

Ukucushwa komkhiqizo

Ukucushwa okujwayelekile: Ukucushwa kwendlela, iphrinta encane.
Izingxenye zokuthenga ozikhethela zona: Ukumiswa kwendlela B, isofthiwe yobungcweti, ikhebula lokuxhumana.

Qaphela: Ngenxa yenqubekelaphambili yezobuchwepheshe, ulwazi luzoshintshwa ngaphandle kwesaziso. Umkhiqizo ungaphansi komkhiqizo wangempela esikhathini esizayo.
