Shore Durometer yog dab tsi thiabNtug Hardness?
Lub Shore Durometer yog ib qho khoom siv uas siv tau los ntsuas qhov hardness ntawm cov khoom tsis yog xim hlau, xws li yas, roj hmab, elastomers, foams thiab lwm yam khoom zoo sib xws. Lub Shore durometer muaj npe tom qab nws tus neeg tsim khoom, Albert F. Shore, uas tau tsim nws hauv xyoo 1920.
Lub ntug dej hiav txwv Durometer ntsuas cov khoom tiv thaiv mus tas li deformation los ntawm nias ib qho tshwj xeeb zoo li indenter tiv thaiv qhov chaw ntawm cov khoom. Lub Shore durometer yog siv los ntsuas qhov hardness ntawm cov khoom ntawm tus lej ntsuas, hu ua Shore hardness scale.
SHORE HARDNESS Scales
Muaj ob peb lub Shore hardness scales siv nyob rau hauv kev lag luam los ntsuas qhov hardness ntawm ntau hom ntawm non-metallic cov ntaub ntawv. Ob qhov kev ntsuas feem ntau yog Shore A nplai thiab Shore D nplai.
SHORE A SIJ HAWM
Shore A nplai yog siv los ntsuas qhov tawv ntawm cov khoom muag, hloov tau yooj yim, xws li roj hmab, elastomers, thiab foams. Lub Shore A nplai muaj kev kawm tiav los ntawm 0 mus rau 100 hardness units.
SHORE B SCALE
Siv los ntsuas qhov hardness ntawm cov ntaub ntawv mos xws li siv quav ciab thiab xab npum.
SHORE C SCALE
Siv los ntsuas qhov nyuaj ntawm cov ntaub ntawv nyuaj xws li cov yas tawv thiab epoxy resins.
SHORE D SCALE
Siv los ntsuas qhov hardness ntawm cov ntaub ntawv nyuaj xws li yas thiab thermoplastic elastomers.
SHORE UA SCALE
siv los ntsuas qhov hardness ntawm cov ntaub ntawv nyuaj heev xws li fiberglass reinforced plastics.
SHORE LUB SIJ HAWM
siv los ntsuas qhov hardness ntawm cov ntaub ntawv mos heev xws li npuas roj hmab.
Txhawm rau siv Shore durometer, lub indenter yog muab tso rau ntawm qhov chaw ntawm cov khoom yuav tsum tau ntsuas, lub zog tas li yog siv, thiab qhov tob ntawm qhov tshwm sim indentation yog ntsuas. Qhov tob ntawm qhov indentation yog siv los txiav txim siab qhov hardness ntawm cov khoom ntawm qhov sib thooj Shore scale.
Lub Shore A durometer feem ntau yog siv nyob rau hauv kev lag luam caster kev lag luam los ntsuas qhov hardness ntawm cov ntaub ntawv los ntawm cov log thiab casters. Hardness yog ib qho tseem ceeb uas yuav tsum tau xav txog thaum xaiv lub log los yog caster, vim nws cuam tshuam rau lub peev xwm ntawm lub log los yog caster los txhawb nqa, yob smoothly, thiab tiv thaiv hauv pem teb.
SHORE HARDOMETER ntawm lub log thiab cov log tsheb
Muaj log thiab casters siv ntau yam kev siv hauv kev lag luam sib txawv, los ntawm kev xa khoom mus rau kev tsim khoom. Kev ntsuas Shore A thiab D durometer yog ib txoj hauv kev los ntsuas qhov nyuaj ntawm cov log thiab cov casters thiab txiav txim siab lawv lub peev xwm los tiv thaiv cov khoom thiab tiv thaiv kev puas tsuaj.
Cov log thiab cov casters nrog qhov loj dua ntawm ntug dej hiav txwv yog qhov nyuaj thiab tsis tshua muaj deformable, ua rau lawv zoo tagnrho rau cov ntawv thov uas yuav tsum muaj peev xwm thauj khoom ntau dua thiab ua kom puas. Cov log thiab cov casters nrog me me rau ntawm ntug dej hiav txwv yog softer thiab deformable dua, uas ua rau lawv haum rau cov kev siv uas muaj peev xwm ntau dua cushioning thiab load tiv thaiv.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias kev ntsuas Shore durometer tsis yog qhov kev txiav txim siab nkaus xwb thaum xaiv cov log tsheb thiab cov casters. Lwm yam tseem ceeb muaj xws li qhov loj me, mounting hom, load peev xwm, thiab compatibility nrog rau saum npoo lawv yuav siv rau.
