Ndlela yo hunguta ntsengo wa rhaba leyi hlanganisaka .

Emisaveni leyi phikizanaka swinene ya bindzu ra rhaba, ntsengo wa ku hlanganisiwa i wa nkoka swinene eka ku humelela ka ikhonomi ya xiendliwa. Swi nga koteka ku tumbuluxa xivumbeko lexi hlanganisiweke lexi fikelelaka swilaveko swa muxavi hi ku ya hi matirhelo hamambirhi, kambe xi ariwa hi muxavi hikuva xi durha ngopfu.

Ku engetela kwalano, switirhisiwa swa rhaba hi xitalo swi xavisiwa hi volume kutlula ntiko (switirhisiwa leswi vumbiweke hi xitalo swina sayizi). Hikwalaho, swa twala ku pimanisa 'cost per volume' ku tlula 'cost per weight' ya rhaba.

Swiendlakalo leswi landzelaka swi nga ha hunguta ku durha ka ikhonomi ya nkatsakanyo. Xiya: Swiendlakalo leswi swa ku ringeta hi ku angarhela swi nga ha va swi nga tirhi eka mhaka yin’wana na yin’wana yo karhi. Xihlawulekisi xin’wana na xin’wana lexi hungutaka ntsengo xi ta khumba hakunene swivumbeko swin’wana, ku antswa kumbe ku biha.

1. Khaboni ya ntima/xifaniso xa pulasitiki .

Ku hlawula khaboni yale henhla ya xivumbeko xa ntima naku tirhisa mafurha ya filler yale henhla swita hlayisa modulus ya compound yiringanela loko ntsengo wuya ehansi.

2. Nhlayo ya ku tata ka khaboni ya ntima .

Anakanya hi ku hlawula ndzhawu yale hansi ya xivumbeko xale hansi na yale hansi ya ndzhawu ya le henhla ya khaboni ya ntima, hikuva khaboni leyi ya ntima ayi chipa ntsena, kambe yitlhela yiva na nhlayo yale henhla yo tata, leswinga hunguta hindlela leyinene ntsengo wa rhaba.

Hlawula ultra-low structured semi-reinforced carbon black, hikuva yinga tatiwa hi nhlayo leyikulu, leswinga hunguta kahle ntsengo wa rhaba.

Hlawula ndzhawu yale hansi yokarhi yale henhla xikan’we na khaboni yale hansi ya ntima kuva yi tata rhaba ya ntsengo wale henhla, naswona hlayisa viscosity ya rhaba yingari e henhla ngopfu, leswaku rhaba yitava yi endliwe injection kumbe ku vulcanized hi tindlela tin’wana, naswona ntsengo wuta hunguteka hiku ringanela.

3. Silica .

Eka ku tiya ka le hansi ka rolling xikan’we naku tiya kahle ka slip, silica yitala kutirhisiwa tani hi filler naswona kutirhisiwa organosilane coupling agent. Ti silane coupling agents ta durha, naswona loko nhlayo yitsongo swinene ya silane coupling agent yinga tirhisiwa naswona matirhelo ya compound ya tshama yanga cinci, ntsengo wa compound wunga hungutiwa swinene. Mukhuva lowu tolovelekeke iku tirhisa silica leyingana high surface hydroxyl content, tani hileswi yinga kamberiwa kuva yi hlanganisiwa hiku olova. Xisweswo, hi mintlawa yotala ya hydroxyl eka compound, ku laveka silane coupling agent yitsongo naswona swivumbeko swa michini leswi fanaka swa hlayisiwa loko ntsengo wuhunguteka.

4. XITLHANYI .

Eka ti compounds to basa leti taleke hi TIO2, swin’wana swa le hansi swa switatisi swo basa swa ntsengo wa le hansi (ku fana na vumba lebyi hlantswiweke hi mati, calcium carbonate, whitening agent, na swin’wana) swi nga tekeriwa enhlokweni ku siva swin’wana swa TIO2, naswona xiaki xa ha ta va na vuswikoti byo karhi byo funengeta na ku basa.

Eka ti tread compounds leti tatiweke hi silica, ku cinca swin’wana swa silica hi carbon black-silica biphasic fillers swinga tlhela swihunguta ntsengo wa compound, hikuva swinga hunguta nhlayo ya silane coupling agent, naswona switlhela swihunguta goza ra heat treatment eka endlelo ro hlanganisa.

Ku tata rhaba hi calcium carbonate swita hunguta swinene ntsengo wa rhaba. Hilaha ku fanaka, vumba byi ta hunguta swinene ntsengo wa xinamarheti.

Hambi leswi density ya talc (2.7g/cm3) yinga yikulu kutlula ya carbon black (1.8g/cm3), loko 1.5 parts (hi mass) ya talc yitirhisiwa ematshan’wini ya 1 part (hi mass) ya carbon black, ntsengo wa compound wunga hungutiwa. Ku engetela kwalano, talc powder yita engetela rivilo ra extrusion xikan’we naku antswisa vuhumelerisi, leswinga ta hunguta hindlela yoka yinga kongomanga eka ntsengo.

5. Ku hungutiwa ka density .

Switirhisiwa swa rhaba hi ntolovelo swi xavisiwa hi volumin ku nga ri hi ntiko. Loko u cinca fomula ya rhaba leswaku density yiva ehansi, loko urikarhi u hlayisa nxavo hi unit volume yinga cinci, kutani unga hunguta hindlela yoka yinga kongomanga ntsengo. Xikombiso, hi ku siva CR hi NBR, ntsengo hi yuniti ya vholumo ya mathonsi ya rhaba, ntsena loko ku cinca kun’wana eka rhaba ku nga siveli ku vuyeriwa loku ka ntsengo.

6. yi sivele ku hlanganisiwa ka magoza mambirhi hi ku hlanganisiwa loku engetelekeke.

Loko swi koteka, ku siva ku hlanganisiwa ka magoza mambirhi hi ku hlanganisiwa ka goza rin’we hi ku tirhisa tithekiniki ta vulawuri bya eneji na ku kamberiwa ka eneji ya phurosese loku tirhaka swi nga tlhela swi hunguta ku durha.

7. Swipfuneti swo lulamisa .

Ku tirhisiwa ka swipfuno swo lulamisa swi nga antswisa rivilo ra ku humesa kumbe ra calendering ra nkatsakanyo, xisweswo swi hunguta ku durha.

8. Ku hlanganisiwa ka FKM/ACM .

Ku cinca pure FKM hi peroxide-cured FKM/ACM blend (DAI-EL AG-1530) swinga endla leswaku rhaba yiva na kuhisa ko antswa xikan’we naku lwisana na mafurha.
