Qee lub sij hawm cov neeg siv tsuas yog thov kom ntev npaum li cas lub pulcanized compound tuaj yeem rub tawm yam tsis muaj tawg. Nov yog lwm qhov tseem ceeb khoom ntiag tug cov cuab yeej hauv kev sim siab kev sim ntawm cov qauv qauv dumbbell raws li tau teev los ntawm Astm thiab ISO. Cov kev cai hauv qab no tuaj yeem pab cov kws sau ua tiav raws cov neeg siv khoom xav tau.

1. SBR

SBR polymerized los ntawm emulsion ntawm -10 ° C thiaj li 50 ° C tuaj yeem muab cov compound zoo tensile elongation.

2. NRG

Ntawm cov qib ntawm NRR, yas yas roj hmab CV60 roj hmab muaj cov tensile loj tshaj plaws.

3. Neoprene thiab fillers

Nyob rau hauv neoprene formulations, inorganic fillers nrog loj particle loj dua li qhov me me particle loj yuav tsum tau siv los txhim kho elongation ntawm lub tensile tawg. Ib qho ntxiv, hloov cov pa roj carbon daus dub nrog cov tshuaj pleev xim kub kub tuaj yeem txhim kho kev sib tsoo ntawm lub tensile.

4. TPE thiab TPV

Thermoplastic elastomers thiab thermoplastic volcanicizes zoo li yog anisotropic elastomers ntawm cov siab tensile elongation thiab tensile lub zog yog nyob ntawm cov kev taw qhia ntawm lawv cov kev lom zem.

5. Carbon Dub

Kev siv cov pa roj carbon dub nrog thaj chaw tshwj xeeb thiab cov qauv qis thiab txo cov pa roj carbon dub tuaj yeem txhim kho lub kaum tensile elongation ntawm lub compound.

6. Talcum hmoov

Hloov cov roj carbon dub nrog cov palc me me yog qhov sib xyaw ua ke, tab sis muaj cov txiaj ntsig me me rau ntawm lub zog tensile thiab tej zaum yuav ntxiv cov modulus ntawm qis hom.

7. Sulfur Vulcanization

Qhov zoo tshaj plaws kom zoo ntawm cov leej faj sib piv nrog peroxide vulcanization yog tias nws tuaj yeem ua cov roj hmab khoom muaj lub taub roj hmab muaj lub siab tshaj elongation. Feem ntau, high-sulfur vulcanization tshuab tuaj yeem tshem tawm tensile zoo dua rau lub compound ntau dua li cov tshuab tsis tshua muaj pa.

8. Gel

Cov khoom siv hluavtaws zoo li sbr feem ntau muaj stabilizers stabilizers. Txawm li cas los xij, kev sib xyaw sbr teb ntawm qhov kub tshaj 163 ° C tuaj yeem qhib cov kua txiv ntoo (uas tuaj yeem muab qhib thiab tsis yog soluble nyob rau qee cov kuab tshuaj). Ob leeg ua kom txo cov tensile elongation ntawm qhov sib txuas, yog li kev sib xyaw ua ke ntawm SBR yuav tsum tau txais kev ceev faj.

9. Sib xyaw

Sib sau ua ke txhim kho cov dispersion ntawm carbon dub, uas pab txhim kho lub tensile elongation ntawm qhov sib txuas.

10. Cov teebmeem ntawm cov roj molecular

Rau cov xyoob roj hmab nyoos, kev siv ntawm Moog Hoone viscosity thiab qhov hnyav molecular hnyav tuaj yeem txhim kho qhov kev ncua ntev ntawm lub tensile. Emulsion SBR, DUAB SBR, BR thiab IR kuj tsim nyog rau qhov no.

11. Qib ntawm vulcanization

Feem ntau, qib qis ntawm vulcanization tuaj yeem ua rau lub siab tensile elongation ntawm lub compound.
