Nzira yekudzikisa sei mari yekubatanidza rabha
Munyika inokwikwidza zvikuru yeindasitiri yerabha, mutengo wekubatanidza wakakosha pakubudirira kwehupfumi hwechigadzirwa. Zvinogoneka kugadzira musanganiswa wemukomboni unoenderana nezvinodiwa nemutengi maererano nemaitiro ese ari maviri, asi unorambwa nemutengi nekuti unodhura zvakanyanya.
Pamusoro pezvo, zvigadzirwa zverabha zvinowanzotengeswa nehuwandu kwete nehuremu (zvigadzirwa zvakaumbwa zvinowanzo hukuru). Naizvozvo, zvine musoro kuenzanisa 'mutengo pavhoriyamu' pane 'mutengo pahuremu' hwerabha.
Mamiriro ezvinhu anotevera anogona kuderedza mutengo wehupfumi wekomboni. Cherechedzo: Aya maratidziro akajairwa anogona kusashanda kune yega yega kesi. Chero chero shanduko inoderedza mutengo inozokanganisa zvimwe zvivakwa, zvirinani kana zvakanyanya.
1. Carbon dema/plasticizer
Kusarudza yakakwira dhizaini kabhoni dema uye kushandisa yakakwira yekuzadza mafuta kunochengeta modulus yekomboni nguva dzose apo mutengo uchidzika.
2. Carbon dema yekuzadza huwandu
Funga kusarudza yakaderera yakarongeka uye yakaderera chaiyo nzvimbo kabhoni dema, nekuti iyi kabhoni dema haina kudhura chete, asiwo ine yakakwira yekuzadza huwandu, iyo inogona kunyatso kudzikisa mutengo werabha.
Sarudza ultra-low structured semi-reinforced carbon black, nokuti inogona kuzadzwa muhuwandu hukuru, iyo inogona kuderedza zvakanyanya mutengo werabha.
Sarudza yakaderera yakananga nzvimbo uye yakaderera yakarongeka kabhoni nhema kuzadza yakakwira mutengo rabha, uye chengetedza viscosity yerabha isiri yakanyanya kukwirira, kuitira kuti rabha rigone kuumbwa kana kupiswa nedzimwe nzira, uye mutengo unodzikiswa zvine mwero.
3. Sirika
Kune yakaderera rolling kuramba uye yakanaka kutsvedza kuramba, silica inowanzoshandiswa sekuzadza uye organosilane coupling agent inoshandiswa. Silane coupling agents inodhura, uye kana shoma shoma ye silane coupling agent inogona kushandiswa uye kushanda kwekomboni kunoramba kusina kuchinja, mutengo wekomboni unogona kuderedzwa zvikuru. Tsika yakajairika ndeye kushandisa silica ine yakakwira yepamusoro hydroxyl yemukati, sezvayakadzidzwa kuti ibatanidzwe nyore nyore. Nekudaro, neakawanda hydroxyl mapoka mukomboni, shoma silane coupling agent inodiwa uye yakafanana mechanical zvivakwa zvinochengetwa nepo mutengo uchideredzwa.
4. Filler
MuTIO2-yakazadzwa machena macompounds, mamwe machena anodhura-akaderera (akadai sevhu rakashambidzwa nemvura, calcium carbonate, whitening agent, etc.) inogona kutariswa kutsiva imwe yeTIO2, uye iyo komputa icharamba iine imwe yekuvhara kugona uye kuchena.
Mune silica yakazadzwa kutsika makomisheni, kutsiva mamwe silica nekabhoni nhema-silica biphasic mafirita anogona zvakare kuderedza mutengo wekomboni, nekuti inogona kuderedza huwandu hweiyo silane coupling agent, uye zvakare kuderedza nhanho yekurapa kupisa mukusanganisa maitiro.
Kuzadza rubber ne calcium carbonate kuchaderedza zvakanyanya mari yerubha. Saizvozvowo, ivhu richaderedza zvakanyanya mari yekunamatira.
Kunyange zvazvo kuwanda kwetalc (2.7g / cm3) yakakura kudarika iyo yekabhoni dema (1.8g / cm3), kana 1.5 zvikamu (nehuwandu) hwetalc inoshandiswa panzvimbo ye 1 chikamu (nehuwandu) hwekabhoni dema, mutengo wekomboni unogona kuderedzwa. Uye zvakare, iyo talc poda ichawedzera iyo extrusion kumhanya uye kuvandudza kuburitsa, izvo zvinozoderedza zvisina kunanga mutengo.
5. Density kuderedza
Zvigadzirwa zverabha zvinowanzotengwa nehuwandu kwete nekurema. Kana iwe ukashandura fomura yerabha kuti density yadzike, uchichengeta mutengo pavhoriyamu yega yega isina kuchinjika, saka unogona kudzikisa mutengo zvisina kunanga. Semuyenzaniso, nekutsiva CR neNBR, mutengo pachikamu chevhoriyamu yerabha inodonha, chero zvimwe shanduko murabha isingadzikisi mutengo uyu.
6. yakatsiva nhanho mbiri-musanganiswa nekuwedzera musanganiswa.
Kana zvichibvira, kutsiva nhanho mbiri-inosanganiswa ne-imwe-nhanho yekubatanidza kuburikidza nemaitiro ekudzora simba uye inoshanda maitiro ekuyedza simba anogona zvakare kuderedza mutengo.
7. Zvishandiso zvekugadzirisa
Iko kushandiswa kwezvibatsiro zvekugadzirisa zvinogona kuvandudza extrusion kana calendering kumhanya kwekomboni, nokudaro kuderedza mari.
8. FKM/ACM kusanganisa
Kutsiva yakachena FKM neperoxide-yakarapwa FKM/ACM musanganiswa (Dai-El AG-1530) inogona kuita kuti rabha rive nekupisa kuri nani uye kuramba kwemafuta.
