Kev faib tawm thiab kev ua tau zoo ntawm cov khau ncaws pob khau:
(1) Roj hmab
Nws yog siv rau lub outsole ntawm ntau yam khau kis las; Qhov zoo: zoo hnav tsis kam, tsis plam, elastic, tsis yooj yim tawg, zoo softness, zoo extensibility, ruaj khov shrinkage, zoo hardness thiab zoo yooj. Disadvantages: hnyav hnyav, yooj yim rau nto qaub ncaug (ib qho teeb meem zoo), tsis yooj yim rau corrode (cov teeb meem tiv thaiv ib puag ncig).
(2) PUV
Cov khoom siv hluavtaws polyurethane siab molecular, feem ntau siv nyob rau hauv nruab nrab ntawm cov khau ncaws pob thiab ntaus pob tesniv, thiab tseem tuaj yeem siv ncaj qha rau hauv lub outsole ntawm cov khau xws li khau. Qhov zoo: siab ceev, siab hardness, hnav tsis kam, zoo elasticity, zoo oxidation kuj, yooj yim rau corrode, environmentally friendly, thiab tsis yooj yim rau wrinkle. Disadvantages: muaj zog nqus dej, yooj yim rau daj, yooj yim tawg, tsis zoo elongation, tsis dej resistant, perishable nyob rau hauv qab.
(3) EVA
Vinyl acetate copolymer, khoom siv polymer. Feem ntau siv nyob rau hauv jogging, taug kev, xws li khau, ko taw kev cob qhia khau midsole. Qhov zoo: lub teeb, zoo elasticity, zoo yoog raws, tsis yooj yim rau wrinkle, muaj xim zoo nkauj, haum rau ntau yam huab cua. Roj hmab. EVA yog cov khoom ua npuas ncauj hauv qab. Nws ua nyuaj thiab tiaj tom qab ntev. Roj hmab yuav tsis. Ntau hnav-resistant. Nws yuav tsum yog roj hmab. Roj hmab yog hnav-tiv taus, thiab kev sib txhuam tsis yog nplua. Nws nyob ntsiag to thaum taug kev. Ob txhais taw kuj xis. Qhov zoo ntawm EVA yog tias nws lub teeb heev, tab sis nws yog nplua heev tom qab hnav nws rau lub sijhawm ntev. . Hnav-resistant lossis roj hmab, EVA ua npuas ncauj khoom yog sib dua.
