Tensile lub zog kev soj ntsuam ntawm cov hnab yas ntim khoom lag luam, elongation, thiab lwm yam khoom ntawm cov hnab lossis cov yeeb yaj kiab kom ntseeg tau tias lawv tawg thaum siv thiab tsheb thauj mus los. Cov qauv siv uas siv tau suav nrog ASTM D882 thiab GB / T 1040.
1. Kev npaj
Khoom siv:
Hluav Taws Xob Hluav Taws Xob (Tensile Tshuab) Nrog Clamps, Tus Hlau Ntsuas (Vernier Caliper, Tus Hlau Storier (Rau Cov Ntawv Sau Tseg (Rau Cov Ntaub Ntawv Sau Tseg
Kev Npaj Tso Tawm:
Kev txiav cov hnoos qeev los ntawm lub hnab ntim khoom lossis cov yeeb yaj kiab ua ke, tsis txhob muaj cov kab ke, luam tawm cov ntsaws ruaj ruaj (tshwj tsis yog qhov kev sim siab tshwj xeeb).
Kev txiav cov hnoos qeev rau cov qauv qhov ntev, feem ntau 15 hli dav X 200 hli dav (lossis raws li cov khoom siv tau los ntawm cov khoom siv thiab cov pob txha).
Tus naj npawb ntawm cov hnoos qeev: ntau dua lossis sib npaug rau 5 cov hnoos qeev hauv txhua qhov kev taw qhia (tshuab kev taw qhia) pom zoo.
Ib puag ncig cov xwm txheej:
Kub: 23 ± 2 Qib
Vaum: 50 ± 5% Rh
Cov zis yuav tsum yog tus tsim kho hauv qhov chaw no rau ntau dua lossis sib npaug rau 4 teev ua ntej kuaj.
2. Kev sim cov txheej txheem
Teeb cov khoom tsis muaj cov khoom:
Gauge ntev: feem ntau 100 mm
CrossHad Ceev: Cov yeeb yaj kiab nyias: 50 hli / min, cov yeeb yaj kiab tuab / hnab: 100 hli: 100 mm / min (kho tau raws li cov qauv kev cai).
Cov me nyuam installation:
Muaj ib qho kawg ntawm cov hnoos qeev mus rau sab saud thiab lwm qhov kawg rau qhov qis dua clamp, ua kom muaj cov quav dev yog qhov tseeb, dawb ntawm twist thiab wrinkles. Ceevfaj tsis txhob ua kev puas tsuaj rau lub sijhawm thaum clamping.
Kuaj Pib:
Pib lub tshuab kuaj thiab pib tensioning qhov hnoos qeev kom txog thaum nws tawg.
Cov twj paj nruag sau tseg tus ** nruj (n) {-
Tom qab kuaj, sau qhov siab tshaj plaws (FMAX) thiab elongation thaum so.
Rov ua qhov kev xeem:
Kuaj cov khoom seem uas siv cov qauv qub.
Xam cov txhais tau tias thiab qauv sib txawv rau txhua txoj kev coj.
3. Sau ntawv
Sim cov kev ntsuas ntev (MD) thiab transverse (TD) cais; Kev ua tau zoo yuav txawv.
Cais cov qauv los ntawm thaj chaw ntawm cov chaw uas muaj peev xwm ua rau lub zog kaw lub zog.
Yog tias lub hnab yog ua los ntawm cov yeeb yaj kiab sib xyaw, paub txog kev pheej hmoo ntawm kev cuam tshuam.
Yog tias cov hnoos qeev tau luam tawm lossis aluminium -}} plated ntug, cov qhab xeem yuav raug cuam tshuam thiab yuav tsum tau sau tseg.
