Shore Hardness ACD Hloov thiab Qhov Sib Txawv
Ntug Hardness Concept
Lub Shore scleroscope hardness (Shore), thawj zaug tau thov los ntawm tus kws tshawb fawb Askiv Albert F. Shore, feem ntau hu ua HS thiab ua tus qauv rau kev ntsuas cov khoom hardness. Lub Shore hardness tester yog tsim rau kev txiav txim siab ntawm Shore hardness tus nqi ntawm ob qho tib si ferrous thiab non-ferrous hlau, nrog rau cov hardness tus nqi sawv cev rau qhov ntev ntawm elastic deformation tshwm sim los ntawm cov hlau. Lo lus no nquag siv hauv kev lag luam roj hmab thiab yas.
Txoj Kev Kuaj
Lub Shore hardness tester yog muab tso rau hauv cov khoom yuav tsum tau ntsuas, tus pointer ntawm lub dial yog txuas nrog ib rab koob los ntawm lub caij nplooj ntoos hlav, thiab rab koob tau muab tso rau hauv qhov chaw ntawm cov khoom yuav tsum ntsuas, thiab tus nqi tso tawm ntawm lub dial yog. tus nqi hardness
Classification thiab Scope of Application of Hardness Tester
Cov qauv siv feem ntau ntawm hardness testers suav nrog Shore A, C, thiab D hom. Txhua tus qauv muaj nws cov kev siv tshwj xeeb: Hom Shore A feem ntau yog siv los kuaj qhov tawv ntawm cov ntaub ntawv yas thiab hluavtaws roj hmab; Lub Shore Type C yog tsim los rau kev txiav txim siab hardness ntawm microporous cov ntaub ntawv uas muaj ua npuas ncauj ua los ntawm roj hmab thiab yas nrog ib tug compression tus nqi ntawm ntau tshaj 0.5kg / c㎡ ntawm 50%, tab sis kuj yuav siv tau rau lwm yam ntaub ntawv uas zoo sib xws; Thaum lub Shore D hom yog tsim rau kev sim hardness ntawm cov roj hmab tawv, tawv resin, acrylic, iav, thermoplastic, luam ntawv phaj, fibers, thiab lwm yam high-hardness cov ntaub ntawv.
Sib piv Table of Shore Hardness A, C, thiab D
Qhov kev txiav txim ACD yuav tsum raug coj mus rau hauv kev txiav txim siab thaum xa mus rau daim duab.
Kev hloov pauv ntawm Shore A Hardness thiab D Hardness
Cov lus saum toj no qhia tau hais tias cov khoom siv nrog Shore hardness qis dua 90A yog ntsuas los ntawm kev ntsuas A, thaum cov ntaub ntawv uas muaj hardness siab dua 90A yog ntsuas los ntawm lub rooj D. Nws yuav tsum tau muab sau tseg tias txoj kev ntsuas rau Shore A thiab Shore D hardness txawv, ua rau tsuas yog kwv yees kev hloov pauv kev sib raug zoo ntawm ob qhov teev. Cov qauv kev hloov pauv yog raws li hauv qab no:
1) D = A – 50;
2) AB = 0.173D + 86.58.
Raws li pom los ntawm cov lus hais saum toj no, qhov kev hloov dua siab tshiab no tsuas yog kwv yees xwb; Yog li ntawd, nws raug nquahu kom xaiv cov hom hardness tester uas tsim nyog raws li qhov yuav tsum tau ua rau kev sim tiag tiag.
