Building Material Umsi malunga noxinaniso Tester
ASTM D2843 Building Material Smoke Density Tester
Iprofayili Product lokuXhotyiswa Material Umsi Ingxinano Tester
Umsi tester for ekwakheni izinto luphuhliswa Rohm Haas Company of America ulawulo lwangaphakathi. It yasungulwa ngo 1970 ngokwendlela ASTM standard D2843. isiseko theoretical component umthetho Billumber kaThixo, oko kukuthi, umsi eziveliswa ngokutshiswa kufunda nefuthe ngqo namadangatye, kwaye umthondo ukukhanya wasikhusela emva avuthayo izinto. Ireyithi agqithisileyo ngoko kusetyenziswa ukumisela ixabiso umsi ingxinano (SDR). Okwangoku, sele kudlule ngakumbi izicelo ezingaphezu koko ukufika kumgangatho GB 8624 wesizwe, kuba umsi lexinene nokuvavanywa PVC istili; kodwa ukuba uvavanyo lwentsebenzo umsi ezinoxinano izinto ngomatshini ingaphakathi.
Iimpawu Performance of Building Material Smoke Density Tester
1. cabinet Testing isale Teflon, nto leyo ukuxhathisa ukukhusele umsi okubangelwa yokutsha nokulondoloza ubomi mveliso kakhulu.
2. Ukufakelwa omhlophe-background ileta ebomvu "YOKUPHUMA" ifonti ezantsi ebhokisini. Ngenxa window ebonisa ngaphaya, abahloli uyakwazi ukwahlula imeko ecacileyo ungapheleli isampula emva koko.
3. umthombo Uvavanyo ukukhanya kwesibane zigqengezelayo, isivamvo photoelectric na lesilicon diode ukukhanya, lesilicon diode ukukhanya cosine yongqanianiso function, kwaye ifakwe umbala filter, leyo amacebo okucoca ngaphandle ukukhanya yelanga infrared ukuba amehlo abantu abakwazi ukubona, kwaye amehlo kakhulu afanayo.
4. Phantsi 276 KPA yengcinezelo inkcukacha eziphambili, uvavanyo isampulu nefuthe namadangatye, kwaye amathontsi zaye nomthelela sokukhuphela abangabancedani.
5. A xi zerhasi zisiza abangabancedani yi 138KPA, leyo combusts nangakumbi amathontsi otyhidiweyo.
6. I-software standard uvavanyo nje ukubonisa yokugqitha izinga ukukhanya Reuters 15s nganye, kodwa zoba ugqithiso test curve. Emva kovavanyo, isoftwe ingabonisa ixabiso lexinene umsi SDR, oko kukuthi, umsi ixabiso elipheleleyo.
7. Xa sokuhlola software, iingxelo uvavanyo amaqela amathathu iisampulu uvavanyo kuhlanganiswa, kunye negophe of SDR Uphuhliso umsi loxinano singa zotywa.
8. software yekhompyutha ingasetyenziswa ukuthelekisa SDR kwamaqela amathathu iziphumo zovavanyo ngexesha elinye, kwaye ngokuzenzekelayo ukugweba ukuba ingaba iziphumo zovavanyo ikwazi ukukhawulelana neemfuno iziphumo zovavanyo.
9. Data ingaba imveliso nge computer, elidityaniswe elizakushicilelwa kwaye ingxelo test okushicilelekayo, kananjalo kube lula kubasebenzisi ukuyisebenzisa.
