Qhov kev ntsuam xyuas ntawm lub zog tsim kua muag yog ua los ntawm kev sim kua muag, thiab cov qauv ntawm cov kua muag kuaj yog cov ris tsho, Delft, crescent thiab lub kaum sab xis. Kev npaj ntawm cov qauv zoo ib yam li cov qauv tensile, nrog rau cov ntsiab lus hauv qab no tau sau tseg.
(1) Thaum txiav cov qauv, cov kev taw qhia ntawm lub bisector ntawm lub kua muag lub kaum sab xis ntawm lub cutter (tuag kev taw qhia) yog raws li cov kev taw qhia dov.
(2) Tus naj npawb ntawm cov qauv yuav tsum tsis pub tsawg tshaj 5.
(3) Siv lub ntsuas tuab tuab nrog qhov tseeb ntawm 0.01mm los ntsuas qhov tuab ntawm tsis pub tsawg tshaj 3 lub ntsiab lus hauv thaj tsam ntawm cov qauv, thiab coj tus nqi nruab nrab raws li qhov tuab ntawm cov qauv. Tus nqi thickness yuav tsis txawv ntawm 2 feem pua ntawm cov nqi noj. Thaum muab piv rau ntau pawg ntawm cov qauv, qhov nruab nrab thickness ntawm txhua pawg ntawm cov qauv yuav tsum nyob rau hauv 7.5 feem pua ntawm qhov nruab nrab thickness ntawm txhua pawg ntawm cov qauv.
Cov kauj ruam rau kev sim kua muag lub zog yog raws li nram no:
(1) Tshawb xyuas cov cuab yeej thiab cov cuab yeej, npaj cov cuab yeej thiab cov cuab yeej, cov cuab yeej cuam tshuam, thiab ntxuav ib puag ncig;
(2) Pib lub tshuab thiab teeb tsa qhov tsis sib xws (xws li ceev, hom, thiab lwm yam);
(3) Clamp tus qauv mus rau ib qho tob hauv lub sab sauv thiab qis grippers thiab ua kom nws tag nrho thiab sib npaug clamped nyob rau hauv ib qho chaw sib luag. Thaum ua tiav qhov kev sim ntawm txoj cai-lub kaum sab xis lossis crescent- cov qauv zoo li tus qauv, kho cov kab ntev ntawm cov qauv nrog cov kev taw qhia tensile thiab clamp nws mus rau sab sauv thiab qis grippers rau qhov tob, yog li kom txaus thiab txawm tias clamping nyob rau hauv txoj hauj lwm sib npaug;
(4) Tom qab muab cov qauv tso rau ntawm lub clamping ntawm lub tshuab ntsuas tensile, kho lub tshuab tensile (xws li siv lub tshuab tensile lub computer, pib lub software los xaiv txoj kev xeem, teeb tsa qhov parameter input loj, thiab lwm yam), pib lub software. kuaj tshuab, thiab kho qhov ntsuas ntawm qhov ceev ceev. Cov qauv yog ncab kom txog rau thaum cov qauv kua muag, thiab cov nqi siab tshaj plaws tau sau tseg.
Calculation of tear strength: T(SZ)=F/d; in the formula, "F" is the force when the sample is torn (the force value should be calculated according to the provisions in GB/T12833, take the median, unit: N) , "d" is the thickness of the sample (mm or cm), T is the tear strength (N/MM or N/cm).
Yam tsawg kawg yog 5 tus qauv yuav tsum muaj rau txhua tus qauv xeem, thiab cov txiaj ntsig kev xeem tau qhia los ntawm qhov nruab nrab, qhov siab tshaj plaws thiab qhov tsawg kawg nkaus ntawm cov qauv hauv txhua qhov kev taw qhia, thiab cov ntaub ntawv raug rau tag nrho cov lej. Tus nqi ib leeg thiab tus nqi nruab nrab ntawm txhua tus qauv yuav tsum tsis txhob ntau tshaj 15 feem pua, thiab tus naj npawb ntawm cov qauv yuav tsum tsis pub tsawg dua 3 tom qab xaiv.
