Khoom Taw Qhia
Cov kev tsheb nqaj hlau khawm hluav taws xob yog cov qauv tseem ceeb uas txuas nrog cov kev sib tw thiab cov phiaj xwm tseem ceeb yog los hloov cov kev sib tw, thiab kev hloov kho qhov kub thiab txias ntawm cov ciav hlau .
Lub ncoo yog qhov tseem ceeb ntawm cov khoom tseem ceeb uas "txuas rau sab saud thiab qis dua"
Cov tub ntxhais lub zog ntawm kev tsheb ciav hlau:
- Buffering thiab poob siab nqus:Thaum lub tsheb ciav hlau khiav, qhov kev cuam tshuam ntau zaus thiab kev co ntawm lub log thiabHlau Ntsia Hlauyog nqus los ntawm txoj kev ywj pheej ntawm cov ntaub qhwv (xws li cov ntaub ntawv roj hmab), thiab txo cov suab nrov ntawm kev khiav ntawm ib puag ncig ib puag ncig .
- Tus mob khaub thuas sib kis tau:Ntsug lub siab thiab lateral thrust borne los ntawm cov ntsia hlau tawg, kom muaj kev sib tw ntawm cov kev ua haujlwm hauv zos, thiab txuas ntxiv lub neej ntawm cov txheej txheem zuag qhia tag nrho .
- Kho kom nce qib:Thaum txoj kev khiav muaj qhov siab me ntsis vim tias hloov cov ntaub qhwv uas muaj peev xwm hloov kho kom zoo nkauj (xws li hloov cov kab sib txuas, thiab kom muaj kev nyab xeeb thiab muaj kev nyab xeeb.
- Rwb thaiv tsev kev sib cais:Hauv cov ntaub ntawv hluav taws xob hluav taws xob, cov ntaub ntawv siv insulating cov ntaub ntawv los thaiv cov kab ke ntawm corroding steels (siv rau kev tsheb ciav hlau muab tso rau thiab cov phiajcim xa) {}}
- Haum rau deformation:Thaum cov kev tsheb ciav hlau nthuav dav thiab kev sib cog lus nrog kev hloov pauv thiab muaj kev ntxhov siab ntau yam tshwm sim los ntawm kev sib txuas lus tsis txaus ntseeg, tab sis kuj tsis yog ua kom muaj kev ntxhov siab ntau dhau los ntawm kev sib tsoo thiab ua rau kev tsheb ciav hlau ntau dhau los ntawm kev sib tsoo thiab ua rau cov tsheb ciav hlau ntau dhau los thiab ua rau cov tsheb ciav hlau tsis txaus ntseeg thiab ua rau cov tsheb ciav hlau tsis txaus ntseeg thiab ua rau cov tsheb ciav hlau ntau dhau los ntawm kev sib tsoo thiab ua rau cov tsheb ciav hlau ntau dhau los ntawm kev sib tsoo thiab ua rau cov tsheb ciav hlau tsis txaus ntseeg thiab ua rau cov tsheb ciav hlau ntau dhau los ntawm kev sib tsoo thiab ua rau cov tsheb ciav hlau ntau dhau los thiab ua rau cov tsheb ciav hlau tsis txaus ntseeg
Wj -8 ywj
Tus wj -8 ywj Pa yog ib qho tseem ceeb ntawm lubWJ -8} fastening system. Nws tau txais ntau yam kev tsim kho tau zoo, nws yog qhov ua haujlwm loj tshaj plaws rau kev sib tw rau cov ciav hlau nyuaj siab
Cov yam ntxwv tseem ceeb ntawm kev ua tau zoo ntawm polyurethane kev co thiab lub suab nrov txo wj {1} ywj ntaub:
- Khoom muaj pes tsawg leeg:Ua los ntawm kev ua tau zoo polyurethane kev coRation-damping thiab suab nrov-txo cov khoom siv tiv thaiv thiab muaj txiaj ntsig zoo
- Qhov hnyav kis:Ua kom muaj kev sib tw ncaj ncaj thiab toj siab .} tsawg dua ntawm.
- Txo txo qis:Zoo heev ntawm kev nqus jolts . nws zoo txiav cia suab nrov thiab taug qab.
- Kev sib haum:Txig tailored rau wj -8 ceev ceev system {}} qhov no ua kom muaj zog blending .
Tus WJ -8 Elastic ncoo ci rau cov xwm txheej thiab kav ntev ntawm cov kev tsheb ciav hlau tsis zoo lossis cov khoom thauj khoom hnyav.

Khoom Siv Kev Ua Tau
Wj {-8 polyurethane ElastoRicer Pad yog polytetrahydrofmethans (MDI) -pased Prepolymer . siv nyob rau hauv lubWJ -8} fastening systemRau kev tsheb ciav hlau siab, nws ua haujlwm rau faib cov tsheb ciav hlau, polyurethane elastomic cov pob hluav taws xob {} {} ceev ceev ceev cov ntaub ntawv * xav tau a dynamic-to-static stiffness ratio of less than 1.35. By introducing naphthalene diisocyanate (NDI) into the elastomeric pad, this ratio can be reduced to below 1.15, resulting in superior resilience performance.
