Nthawi zina ogwiritsa ntchito amatha kungofunsa momwe mankhwala olakwika amatha kutulutsidwa popanda kuphwanya. Iyi ndi katundu wina wofunika kwambiri m'mayeso opanikizika ndi nkhawa za Dumbbell monga zafotokozedwera ndi Astm ndi ISO. Ma protocol otsatirawa atha kuthandiza opanga amakumana ndi zosowa za ogwiritsa ntchito.
1. SBR
SBR Polymered ndi Emulsion nthawi -10 ° C mtunda wa 50 ° C imatha kupatsanso gawo labwino kwambiri.
2. Nr
Pakati pa magulu osiyanasiyana a NR, pulasitiki ya pulasitiki Chubrab Chubhary ali ndi vuto lalikulu kwambiri.
3. Neoprene ndi mafilimu
Mu neoprene mapangidwe, ogwiritsa ntchito atorganic okhala ndi tinthu tating'onoting'ono osati tinthu tating'onoting'ono tiyenera kugwiritsidwa ntchito kukonzanso kutalika kwa nthawi yopuma kwa tansile. Kuphatikiza apo, kusinthana kaboni yakuda kapena yolimbikitsidwa yolimbikitsidwa ndi kaboni yakuda ya carbon imatha kusintha nthawi yopuma kwa tansile.
4. Tpe ndi TPV
Mafuta a Thermoplastic ndi ma armoplactizatizatiza amatenga anisotropic, makamaka kwa jakisoni wokumba magazi pamtengo wambiri, pomwe mphamvu yayikulu ndi chimbudzi chimadalira kuwongolera.
5.. Kaboni wakuda
Kugwiritsa ntchito kaboni wakuda ndi malo otsika kwambiri ndi mawonekedwe otsika ndikuchepetsa kuchuluka kwa kaboni wakuda amatha kusintha mawonekedwe a tensile.
6. Talcum ufa
Kusinthanso kuchuluka kwa kaboni kwambiri ndi tinthu tating'ono tating'ono tating'ono talc kumatha kusintha mmwamba mphamvu ya tensile yamphamvu, koma sikuthandiza kwambiri pamphamvu yochepa ndipo imatha kuwonjezera modulus pang'ono.
7.. Sulfur Vulcanza
Ubwino Wapamwamba wa sulfure poyerekeza ndi Peroxide Vulcananization ndikuti zitha kupangitsa kuti khungu la mphira likhale ndi mphamvu yayitali kwambiri. Nthawi zambiri, makina okwera a sulufution amatha kupatsirana bwino kwambiri kuposa momwe amaphatikizira madeti otsika.
8. Gel
Zochita zopanga monga SBR nthawi zambiri imakhala ndi okhazikika. Komabe, kusakaniza ma sbr kumapanga kutentha pamwamba pa 163 ° C kumatha kupanga ma gels omasuka (omwe amatha kutsegulidwa) ndi ma gels ang'onoang'ono (omwe sangakhale osungunuka m'malo ena). Madeti onsewa amachepetsa mphamvu ya Tunsile ya Contround, kotero kutentha kosakanikirana kwa SBR kuyenera kuthandizidwa.
9. Kuphatikiza
Kuchulukitsa kumathandizanso kubalalika kwa kaboni wakuda, komwe kumathandizira kukonza mawonekedwe a Tensile kuwirikiza.
10. Zotsatira za zolemera
Kwa NBR yaiwisi ya rack, kugwiritsa ntchito mawonekedwe otsika a Moone Ourcctotion ndi kulemera kochepa kumatha kusintha nthawi yayitali yopuma. Emulsion sbr, kusungunuka sbr, Brr ndi IR ndi yoyenera pa izi.
11. Kuchuluka kwa Vulcananition
Mwambiri, digiri yotsika ya Vulcananition imatha kuyambitsa kutalika kwa chimphona.
