Kev tuav pov hwm kev ua haujlwm khau yuav tsum tau them nyiaj tshwj xeeb rau kev hnav khaub ncaws ntawm cov neeg ua haujlwm. Cov ntaub ntawv sib txawv ntawm kev poob siab tuaj yeem siv los ua kom muaj kev sib txawv ntawm kev poob siab:
1. EVA tam sim no yog cov khoom siv dav siv ntau tshaj plaws rau kev tsim cov khau kev tuav pov hwm kev ua haujlwm, feem ntau yog siv hauv midsole. Cov khoom tseem ceeb yog vinyl acetate vinegar, ethylene n-butyl acrylate polymer, thiab lwm yam, thiab tsim elastomer tom qab foaming. Kho tus neeg sawv cev tshuab muab cov khoom sib txawv hardness thiab elasticity. Cov muab tub lim feem ntau yog titanium dawb hmoov, zinc oxide, calcium carbonate, thiab lwm yam, thiab cov nyiaj ntau dhau ua rau cov txheej txheem compression loj thiab me me elasticity. Ntxiv PE tuaj yeem ua rau muaj qhov nro thiab tearing quab yuam, tab sis qhov elasticity tsis zoo thiab nws yooj yim rau lo rau kev tswj.
2, PU polyurethane tuaj yeem siv rau midsole thiab outsole ntawm cov khau ua haujlwm. Yog vim li cas vim li cas polyurethane siv yog vim nws muaj kev hnav tsis kam, zoo elasticity thiab lub teeb yuag. Tsis zoo rub tom qab foaming, tiv taus kev laus.
3, roj hmab feem ntau yog siv nyob rau hauv outsole ntawm kev tuav pov hwm cov neeg ua haujlwm khau, yog vim li cas vim li cas xaiv roj hmab rau poob siab absorbing cov ntaub ntawv, feem ntau yog vim lub elasticity zoo ntawm npuas roj hmab, yog ib tug tshwj xeeb shock-absorbing roj hmab. Nyob rau hauv dav dav-lub hom phiaj roj hmab, butyl roj hmab thiab nitrile roj hmab muaj ib tug loj damping coefficient; styrene-butadiene roj hmab, neoprene, silicone roj hmab, urethane roj hmab, thiab ethylene-propylene roj hmab muaj nruab nrab damping coefficients; natural roj hmab thiab butadiene roj hmab muaj qhov qis tshaj damping coefficient. Txawm hais tias cov roj hmab ntuj muaj qhov tsawg tshaj plaws damping coefficient, nws muaj kev ua tau zoo, kev qaug zog zoo, tsis tshua muaj cua sov, me me creep thiab zoo adhesion rau hlau. Yog li ntawd, ntuj roj hmab yog dav siv nyob rau hauv shock absorbing roj hmab. Yog tias nws yuav tsum tau tiv taus qhov kub thiab txias, nws tuaj yeem siv ua ke nrog cis-butadiene roj hmab; Thaum nws yuav tsum tau tiv thaiv kev laus, nws tuaj yeem siv ua ke nrog chloroprene roj hmab; Thaum cov roj yuav tsum tau ua, nws tuaj yeem siv ua ke nrog cov roj hmab butyl nrog cov ntsiab lus acrylonitrile tsawg, thiab nws yuav tsum muaj qhov kub thiab txias tsis zoo. , feem ntau siv silicone roj hmab. Cov roj hmab ntuj feem ntau yuav tsum tau ua kom qis qis; butyl roj hmab tuaj yeem siv tau thaum yuav tsum tau ua kom damping siab. Qee cov roj hmab uas muaj cua sov zoo, xws li fluororubber, acrylate roj hmab, EPDM roj hmab, silicone roj hmab, hydrogenated nitrile roj hmab, chlorosulfonated polyethylene, copolychlorohydrin roj hmab, vim lawv qhov siab deformation qaug zog thiab kev ntseeg siab nrog cov hlau sib txuas tsis zoo, yog li nws tsis tsim nyog. rau shock absorbing roj hmab.
