Minkarhi yin’wana vatirhisi va nga ha kombela ntsena leswaku xiaki xa vulcanized xi nga kokiwa nkarhi wo tanihi kwihi handle ko tshoveka. Leyi i nhundzu yin’wana ya nkoka ya swilo eka ku kamberiwa ka ntshikelelo-ntshikelelo wa swikombiso swa dumbbell swa ntolovelo tanihilaha swi boxiweke hakona hi ASTM na ISO. Tiphurotokholo leti landzelaka ti nga pfuna vaendli va tifomula ku fikelela swilaveko swa vatirhisi.

1. SBR .

SBR polymerized hi emulsion eka -10 °C ematshan’wini ya 50 °C yinga nyika compound ku leha ka tensile ku antswa.

2. NR .

Exikarhi ka tigiredi to hambana ta NR, rhaba ya rhaba ya ntumbuluko leyi endliweke hi pulasitiki ya CV60 yi na ku leha ka le henhla ka tensile.

3. Neoprene na swilo swo tata .

Eka ti neoprene formulations, ti inorganic fillers letingana vukulu bya ti particle letikulu kutlula vukulu bya ti particle letintsongo tifanele kutirhisiwa ku antswisa ku leha ka tensile break. Ku engetela kwalaho, ku siva khaboni ya ntima leyi tiyisiweke kumbe leyi tiyisisiweke hi semi-reinforced hi khaboni leyi nga ni ku pandzeka loku hisaka swi nga antswisa ku leha ka ku wisa ka ku tsana.

4. TPE na TPV .

Ti elastomers ta thermoplastic na ti thermoplastic vulcanizates titala kuva ti anisotropic, ngopfu ngopfu eka ti injection molded elastomers eka ti shear rates tale henhla, laha tensile elongation na tensile strength swiya hi tlhelo ra ku khuluka ka tona ka processing.

5. Khaboni ya ntima .

Ku tirhisiwa ka carbon black leyingana ndzhawu yale hansi yale henhla na xivumbeko xale hansi xikan’we naku hunguta nhlayo ya ku tatiwa ka carbon black swinga antswisa ku leha ka tensile ka compound.

6. phoyizeni ya talcum .

Ku cinca nhlayo leyi fanaka ya carbon black hi small particle size talc swinga antswisa tensile elongation ya compound, kambe swina mbuyelo wutsongo eka matimba ya tensile naswona swinga engetela modulus eka strain yale hansi.

7. Ku vulcan ka sulphur .

Nchumu lowu humelelaka swinene wa sulfur loko wu pimanyisiwa na peroxide vulcanization ikunga endla leswaku nchumu wa rhaba wuva na elongation yale henhla ya tensile. Hiku angarhela, ti high-sulfur vulcanization systems tinga nyika elongation yo antswa ya tensile eka compound kutlula ti low-sulfur vulcanization systems.

8. GEL .

Swinamarheti swa synthetic swofana na SBR hi xitalo swina ti stabilizers. Hambiswiritano, ku hlanganisa ti compounds ta SBR eka mahiselo yale henhla ka 163°C swinga humesa ti gels letinga olova (letinga rhendzeriwaka hi ti gels letintsongo) xikan’we na ti compact gels (letinga rhendzeleki ti pfuleka naswona tinga nyawuli eka ti solvents tokarhi). Ti gels leti hatimbirhi ti hunguta tensile elongation ya compound, hikokwalaho mahiselo yo hlanganisa ya SBR yafanele ku tshunguriwa hi vukheta.

9. Ku hlanganisa .

Ku hlanganisiwa swiantswisa ku hangalaka ka carbon black, leswi pfunetaka ku antswisa ku leha ka tensile ka compound.

10. Vuyelo bya ntiko wa molekhuli .

Eka NBR raw rubber, kutirhisiwa ka low mooney viscosity xikan’we na ntiko wale hansi wa molecule swinga antswisa ku leha ka tensile break. Emulsion SBR, dissolved SBR, BR na IR na swona swi lulamerile eka leswi.

11. Digiri ya Vulcanization .

Hiku angarhela, xiyimo xale hansi xa vulcanization xinga endla leswaku kuva na ku leha lokukulu ka tensile ka compound.
