Ob leeg EPDM ua npuas ncauj thiab silicone ua npuas ncauj yog siab -cov ntaub ntawv elastic foaming, tab sis lawv txhua tus muaj lawv tus kheej tsom thiab tsim nyog rau ntau qhov chaw.
(一) Zoo sib xws
Txawm hais tias lawv cov tshuaj sib txawv, raws li cov ntaub ntawv foaming, lawv qhia qee qhov tseem ceeb sib xws:
1.Porous elastic qauv: Ob qho tib si yog tsim los ntawm cov txheej txheem tshuaj lom neeg lossis lub cev ua npuas dej thiab muaj ntau qhov me me kaw- cell los yog cov txheej txheem ntawm tes txuas ntxiv hauv, uas ua rau lawv muaj peev xwm ua tau zoo heev thiab muaj peev xwm sib khi.
2.Outstanding kub tsis kam: Piv nrog cov yas foams (xws li EVA thiab PE), ob qho tib si muaj qhov dav ntawm qhov kub thiab txias thiab tuaj yeem tuav elasticity nyob rau hauv ib puag ncig saum toj no -60℃mus rau 150 degree, thiab tuaj yeem tiv taus kub dua rau lub sijhawm luv luv.
3. Cov tshuaj tiv thaiv zoo heev thiab kev laus ua haujlwm: Ob leeg muaj kev tiv thaiv zoo rau dej, noo noo, ozone, polar chemicals (xws li cawv, tshuaj ntxuav), thiab lwm yam, thiab muaj lub neej ua haujlwm ntev.
4.Electrical rwb thaiv tsev: Cov khoom siv hauv paus nws tus kheej yog cov khoom siv hluav taws xob zoo, thiab cov cuab yeej no tau khaws cia tom qab foaming. Nws yog feem ntau siv rau hauv kev sib khi thiab daim ntaub ntawv buffering uas yuav tsum tau rwb thaiv tsev.
5.Environmentally friendly and non-toxic: High-zoo EPDM thiab silicone foam cov ntaub ntawv tuaj yeem dhau cov ntawv pov thawj cuam tshuam (xws li RoHS, REACH, UL), tsis muaj cov hlau hnyav lossis phthalates, thiab tuaj yeem siv rau hauv kev kho mob, khoom noj khoom haus thiab cov khoom siv me nyuam mos.
6.Customizability: Lub hardness, ntom, xim, foaming piv thiab nto morphology ntawm ob leeg yuav raug kho raws li yuav tsum tau.
(2) qhov sib txawv
Qhov no yog tus yuam sij rau kev xaiv cov khoom siv. Lawv qhov sib txawv tseem ceeb yog los ntawm kev hloov pauv hauv lawv cov qauv tshuaj molecular.
|
Yam ntxwv |
EPDM ua npuas ncauj |
Silicone ua npuas ncauj |
|
Tshuaj lom neeg |
Triple ethylene propylene roj hmab, carbon saw saturated roj hmab. |
Silicone roj hmab, ib qho inorganic organic polymer uas nws cov saw tseem ceeb muaj silicon -oxygen bonds (Si-O). |
|
kub kam rau ua |
Zoo heev. Feem ntau -60℃rau 150 degree. |
Zoo heev. Feem ntau -60℃~ 250 degree, tshwj xeeb silicone tuaj yeem ncav cuag ntau dua 300℃. Lub sijhawm ntev kev ruaj ntseg ntawm qhov kub siab tshaj li EPDM. |
|
Roj kuj thiab hnyav kuj |
Tsis zoo rau roj av, roj, hydrocarbon solvents thiab concentrated acids. Yooj yim rau o. |
Zoo heev. Kev tiv thaiv zoo heev rau cov uas tsis yog - cov roj polar, roj roj thiab cov kuab tshuaj feem ntau. |
|
compression txheej |
Zoo. Nws tuaj yeem ua tiav ntawm qib qis los ntawm kev ua kom zoo dua qub. |
Zoo heev. Nws muaj peev xwm tswj tau qhov tsis tshua muaj compression deformation nyob rau hauv ntau qhov kub thiab txias, uas yog, muaj peev xwm ntawm rebound rov qab tom qab ntev - lub sij hawm compression. |
|
Physiological inertia thiab tsis hnov tsw |
Zoo, tab sis ib co formulations yuav muaj ib tug me ntsis tsw. |
Zoo heev. Tsis muaj saj los yog tsw, nrog zoo heev physiological inertia, thiab zoo biocompatibility nrog tib neeg lub cev. |
|
hluav taws kub |
Nws yog flammable thiab yuav tsum tau ntxiv nrog nplaim retardant kom ua tiav cov nplaim retardant qib. |
Yug nplaim retardant. Silicone tsis hlawv hauv nplaim taws, tab sis tsuas yog carbonizes, nyob rau hauv txoj kab nrog UL94 V-0 thiab lwm cov qauv hluav taws kub retardant. |
|
tuav cov yam ntxwv |
Kev ua haujlwm yog qhov yooj yim thiab raug nqi tsawg. |
Cov khoom siv thiab cov txheej txheem yuav tsum siab dua, thiab cov khoom siv raw thiab cov nqi tsim khoom yog siab dua EPDM. |
|
Tes hnov thiab nto |
Khoom zoo, nrog kev ntxhib los mos ntawm roj hmab. |
Kev xav ntawm tes yog qhov muag heev thiab du. |
|
Gas permeability |
Nws muaj qhov cuam tshuam zoo rau dej vapor. |
Cov khoom siv silicone ua npuas dej feem ntau muaj cov cua permeability siab heev (rau dej vapor, huab cua). |
