DRK135 Falling Dart Impact Tester

I-DRK135 yokuvavanya impembelelo yedathi ewayo isetyenziselwa ukumisela ubunzima bempembelelo kunye namandla e-50% yefilimu yeplastiki okanye iiflakes phantsi kweempembelelo zomphakamo onikiweyo weedli eziwa simahla ezinobunzima obungaphantsi kwe-1mm.

Uvavanyo lwe-dart drop drop luhlala lukhetha indlela yenyathelo ekufuneka yenziwe, kwaye indlela yenyathelo yahlulwe ibe yi-dart drop impact A method kunye ne-B method.

Umahluko phakathi kwezi zibini: ububanzi bentloko ye-dart, izinto eziphathekayo kunye nokuphakama kokuhla kuyahluka. Ngokubanzi, iNdlela A ifanelekile kwizinto ezinobunzima bomonakalo we-50g～2000g. Indlela B ifanelekile kwizinto ezinobunzima bomonakalo wempembelelo ye-300g ukuya kwi-2000g.
Phakathi kwabo, indlela ye-cascade ye-GB / T 9639 kunye ne-ISO 7765 ziindlela ezilinganayo.
Indlela A: Ubukhulu bentloko yedart yi-38±1mm. Izinto eziphathekayo zentloko yedart zenziwe nge-aluminium egudileyo kwaye epholisiweyo, iplastiki ye-phenolic okanye ezinye izinto ezinobunzima obuphantsi obunobunzima obufanayo. Umphakamo wokuhla yi-0.66±0.01m.
Indlela B: Idayamitha yentloko yedathi ewayo yi-50±1mm. Izinto eziphathekayo zentloko yedart zenziwe ngentsimbi egudileyo, epholisiweyo engenasici okanye ezinye izinto ezinobunzima obufanayo. Ubude obuwayo yi-1.50 ±0.01m. Kwi-ASTM D1709, ububanzi bentloko yedart yendlela A kunye nendlela B yi-38.1±0.13mm kunye ne-50.8±0.13mm, ngokulandelanayo.

Iimbonakalo

1. Imodeli yomatshini inoveli, uyilo lokusebenza lunolwazelelelo, kwaye imigangatho yelizwe kunye nemigangatho yamazwe ngamazwe iyahambelana ngexesha elifanayo.
2. Indlela yovavanyo A, B imowudi ezimbini.
3. Idatha yovavanyo Inkqubo yovavanyo ihlakaniphile, ephucula kakhulu ukusebenza kakuhle.
4. Isampuli igxininiswe nge-pneumatically kwaye ikhululwe, okunciphisa impazamo yovavanyo kunye nexesha lokuvavanya.
5. Inkqubo yeparamitha yedatha LCD ukubonisa.

Usetyenziso

Iifilimu kunye namaphepha zifanelekile ukuvavanywa kokumelana neempembelelo zeefilimu zeplastiki, amaphepha kunye neefilimu ezidibeneyo ezinobunzima obungaphantsi kwe-1mm. Njengefilimu ye-PE ye-cling, ifilimu eyolulayo, i-PET sheet, iingxowa zokupakisha ukutya kwezakhiwo ezahlukahlukeneyo, iingxowa zokupakisha ezinzima kunye nezinye iifoyile ze-aluminium, ifilimu edibeneyo ye-aluminium-plastiki, ifanelekile kuvavanyo lokumelana nempembelelo ye-aluminium foil, ifilimu ye-aluminium-plastiki edibeneyo, iphepha, uvavanyo lwekhadibhodi Isetyenziselwa ukuvavanya ukuchasana kwempembelelo yephepha kunye nekhadibhodi.
umgangatho wobugcisa. Ekuqaleni kovavanyo, khetha kuqala indlela yokuvavanya, uqikelele ubunzima bokuqala kunye nexabiso le-Δm, kwaye wenze uvavanyo. Ukuba isampuli yokuqala iphukile, sebenzisa ubunzima Δm ukunciphisa ubunzima bomzimba obuwayo; ukuba isampuli yokuqala ayiphulwanga, sebenzisa ubunzima Δm ukwandisa Umgangatho womzimba owelayo uvavanywa ngokufanelekileyo. Ngamafutshane, ukusetyenziswa kobunzima bokunciphisa okanye ukwandisa ubunzima bomzimba owelayo kuxhomekeke ekubeni isampuli yangaphambili yonakaliswe. Emva kokuba imizekelo engama-20 ihlolwe, bala inani elipheleleyo lomonakalo N. Ukuba i-N ilingana ne-10, uvavanyo lugqityiwe; ukuba i-N ingaphantsi kwe-10, emva kokugcwalisa umboniso, qhubeka novavanyo kude kube ngu-N ulingana no-10; ukuba i-N ingaphezulu kwe-10, emva kokuzalisa kwakhona i-specimen, qhubeka novavanyo kude kube inani elipheleleyo labangonakaliswanga lilingana ne-10, kwaye ekugqibeleni umphumo wempembelelo ubalwa ngokuzenzekelayo yinkqubo. Isixhobo sihambelana ne-GB9639, i-ASTM D1709, i-JISK7124 kunye neminye imigangatho kunye nemimiselo efanelekileyo.

Ipharamitha yemveliso

Ubumbeko lwemveliso

Ubumbeko olusemgangathweni: Ubumbeko lwendlela, umshicileli omncinci.
Amacandelo okuthenga ngokuzikhethela: Ulungelelwaniso lweNdlela ye-B, isoftware yobuchwephesha, intambo yonxibelelwano.

Qaphela: Ngenxa yenkqubela phambili yezobuchwepheshe, ulwazi luya kutshintshwa ngaphandle kwesaziso. Imveliso ixhomekeke kwimveliso yokwenene kwixesha elizayo.
