Raws li GB/T 1179-2017 thiab GB/T 3428 tus qauv, qhov kev xeem tsim nyog ntawm steel-cored aluminium stranded hlau yuav tsum muaj kev pov thawj ntawm cov khoom tseem ceeb xws li cov qauv qhov ntev, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, thiab cov txheej txheem galvanized kom ntseeg tau tias nws ua tau raws li kev tsim thiab kev ua haujlwm.
Ob qho qauv no ua ke ua lub hauv paus tseem ceeb rau kev txiav txim siab zoo ntawm cov hlau -cored aluminium stranded hlau: GB / T 1179-2017 qhia tag nrho cov kev mob thiab kev sim rau tus neeg xyuas pib, thaum GB / T 3428 tsom rau kev ua tau zoo ntawm galvanized steel hlau, tshwj xeeb tshaj yog muab cov txheej txheem tshwj xeeb rau tensile zog, zinc txheej.
Cov txheej txheem kev xeem tseem ceeb thiab cov qauv tsim nyog yog raws li hauv qab no:
Kev soj ntsuam ntawm tus qauv Dimension
Ntsuas tag nrho cov kab sab nraud ntawm cov hlua khi, txoj kab uas hla ntawm txhuas ib lub xaim thiab cov tub ntxhais hlau, lub suab piv, thiab cov kev taw qhia stranding (feem ntau yog txheej txheej sab nraud yog txoj cai - tes Z - kev taw qhia).
Siv lub ntsuas micrometer lossis laser txoj kab uas hla los xyuas kom meej tias qhov sib txawv ntawm qhov sib txawv nyob hauv ± 1% ntawm tus nqi nominal. Kev sib raug zoo yuav tsum tau zam kom tsis txhob "lantern-zoo li" lossis xoob strand tshwm sim.
Mechanical Performance Testing (Core Ntsuas: Tag Nrho Tensile Strength (RTS))
Tensile xeem yog ua nyob rau hauv ib tug universal xeem tshuab, nrog rau loading tus nqi tswj ntawm 10 thiab 30 mm / min.
Kev lees txais: Qhov ntsuas tag nrho lub zog tensile (RTS) yuav tsum tsis txhob qis dua 95% ntawm tus nqi nominal, thiab yuav tsum tsis txhob muaj kev poob qis lossis kev puas tsuaj kawg ua ntej tawg.
Qhov chaw tawg yuav tsum tau sau tseg. Yog tias qhov tawg ntawm qhov chaw nyob hauv 1 cm ntawm qhov sib dhos thiab tsis ua raws li tus qauv tus nqi, nws tuaj yeem rov kuaj dua (ntau tshaj 3 zaug).
Ib txhij, qhov kev ntxhov siab, elastic modulus, thiab elongation ntawm so ntawm 1% elongation yog ntsuas rau sag thiab nro tsim.
Kev Ntsuas Hluav Taws Xob
Lub DC tsis kam ntawm 20℃yog ntsuas siv plaub-terminal micro-ohmmeter kom tshem tawm qhov cuam tshuam ntawm kev tiv thaiv.
Kev lees txais: Qhov ntsuas ntsuas tus nqi yuav tsum tsis pub tshaj 102% ntawm tus qauv teev tus nqi, thiab peb qhov -theem imbalance tus nqi yuav tsum tswj tsis pub dhau 2%.
Infrared thermal imaging tuaj yeem siv los ntsuas kev ua haujlwm kub nce tus yam ntxwv, tsis ncaj qha cuam tshuam txog kev ua haujlwm zoo.
Galvanized Txheej Kev Tshuaj Xyuas Zoo (raws li GB / T 3428)
Zinc Layer Adhesion Test: Tightly qhwv cov hlau xaim nyob ib ncig ntawm ib puag ncig ntawm txoj kab uas hla uas tau teev tseg rau 8 lem, tom qab ntawd tshem tawm thiab rov qhwv, xyuas kom tawg lossis tev.
Zinc Txheej Qhov Ntsuas Qhov Ntsuas: Siv cov txheej txheem tooj liab sulfate etching, xav tau Class A lossis Class B corrosion resistance, nrog tsawg kawg 4 etching cycles.
Cov zinc txheej loj ntawm ib chav tsev yuav tsum siab dua los yog sib npaug rau 86g/m² kom ntseeg tau ntev - lub sij hawm corrosion kuj.
Surface thiab txheej txheem tshuaj xyuas
Pom pom qhov chaw ntawm aluminium hlau thiab steel tub ntxhais rau smoothness, tawg, burrs, oxidation, los yog roj stains.
Lub stranding yuav tsum yog uniform thiab nruj, tsis muaj misalignment los yog xoob strands. Cov pob qij txha yuav tsum sib npaug nrog qhov sib nrug ntau dua 15mm.
Lwm Cov Kev Xeem Tshwj Xeeb (raws li xav tau)
Winding Test: Tshawb xyuas qhov toughness ntawm ib lub xaim nyob rau hauv rov qab khoov kom tsis txhob tawg thaum lub sij hawm tsim kho.
Kev qaug zog thiab nkag mus kuaj: Simulate cua vibration thiab ntev - lub sij hawm thauj khoom los ntsuas lub neej kev pabcuam, yuav tsum muaj qhov tawg tsawg dua lossis sib npaug li 0.5% tom qab ib lab cycles.
