Super lub teeb siab elastic Ib puag ncig-phooj ywg EVA foaming khoom npaj

Cov teeb meem tshwj xeeb yog raws li hauv qab no: ua ntej, qhov kub ntawm cov tshuaj foaming tus neeg sawv cev yuav tsum tau siab tshaj qhov kub ntawm EVA yog ze rau melting los ntawm EVA chemical foaming txheej txheem, thiab decomposition kub ntawm cov tshuaj foaming tus neeg sawv cev yog dav heev. thiab cov txheej txheem decomposition cuam tshuam nrog cov tshuaj sib npaug, yog li cov tshuaj foaming tus neeg sawv cev tseem nyob hauv ntau cov khoom siv matrix tom qab foaming tiav, kev ntsuas ntawm refining qhov kub-kub EVA nyob rau hauv lub xeev unmelted thiab nce ntxiv ntawm ib tug series ntawm pab. Cov neeg sawv cev xws li tus neeg sawv cev sib txuas, stearic acid, tus neeg sawv cev hla kev sib txuas, cov tshuaj foaming tus neeg sawv cev decomposition catalyst, plasticizer thiab cov zoo li feem ntau tau txais hauv kev lag luam los txo cov kev cuam tshuam ntawm cov residual foaming tus neeg sawv cev ntawm cov foaming kev ua tau zoo. cov khoom siv, tab sis cov kev ntsuas ncaj qha ua rau muaj qhov loj ntawm micromolecular auxiliary agents yooj yim mus rau hauv cov khoom kawg, thiab cov neeg pab cuam txuas ntxiv mus rau saum npoo ntawm cov khoom los ntawm sab hauv nrog rau kev siv ntev, kom cov kab mob ntawm daim tawv nqaij los yog lwm cov pa phem tiv tauj nrog cov khoom yog tshwm sim;Thib ob, nyob rau hauv cov txheej txheem tshuaj foaming, qhov decomposition ntawm cov tshuaj tshuab tshuab txiav txim siab tus cwj pwm foaming thiab cov tshuaj crosslinking txiav txim siab yaj rheology tus cwj pwm mus ib txhij, thiab qhov kub thiab txias haum rau decomposition ntawm cov tshuaj tshuab tshuab tsis yog qhov kub tshaj plaws haum rau. lub yaj rheology rau cell nucleation thiab kev loj hlob.Tsis tas li ntawd, cov tshuaj foaming tus neeg sawv cev thiab cov tshuaj crosslinking yog cov txheej txheem dynamic uas ua haujlwm tsis tu ncua nrog lub sijhawm, thiab qhov kub thiab txias dependence muaj zog heev.Cov txheej txheem rau kev npaj EVA ua npuas ncauj los ntawm cov tshuaj foaming txoj kev yuav tsum xav txog crosslinking thiab foaming tib lub sij hawm kom qhov optimization ntawm cell qauv yog nyuaj.

Txhawm rau daws cov teeb meem saum toj no, cov tuam txhab tsim khoom tau nquag ua haujlwm tshawb nrhiav thiab kawm.Kev sib xyaw ntawm EVA foamed khoom thiab lwm yam ntaub ntawv elastomer tau dhau los ua kev tshawb fawb kub ntawm cov khau manufacturers.
