Ndlela yo hunguta ku durha ka ku hlanganisa rhaba

Emisaveni leyi phikizanaka swinene ya bindzu ra rhaba, ntsengo wa compounding i wa nkoka swinene eka ku humelela ka ikhonomi ya xitirhisiwa. Swinga koteka ku tumbuluxa xivumbeko xa compound lexi fikelelaka swilaveko swa muxavi hi tlhelo ra matirhelo hivumbirhi bya swona, kambe xi ariwa hi muxavi hikuva xi durha ngopfu.

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

Swiendlakalo leswi landzelaka swi nga hunguta ku durha ka ikhonomi ya xivandla. 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 hakunene xi ta khumba tindhawu tin’wana, ku antswa kumbe ku biha.

1. Khaboni ya ntima/xitirhisiwa xo endla pulasitiki

Ku hlawula carbon black ya xivumbeko xale henhla xikan’we naku tirhisa oyili ya filler yale henhla swita hlayisa modulus ya compound yinga cinci loko ntsengo wuri karhi wu ya ehansi.

2. Nhlayo ya ku tata ya khaboni ya ntima

Anakanya hiku hlawula xivumbeko xale hansi na ndzhawu yale hansi yokarhi yale henhla ya carbon black, hikuva carbon black leyi ayi chipa ntsena, kambe yitlhela yiva na nhlayo yale henhla yo tata, leswinga hungutaka kahle ntsengo wa rhaba.

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

Hlawula ndzhawu yale hansi yokarhi yale henhla xikan’we na carbon black leyinga na xivumbeko xale hansi ku tata rhaba ya ntsengo wale henhla, naswona hlayisa viscosity ya rhaba yingari e henhla ngopfu, leswaku rhaba yinga endliwa injection molded kumbe vulcanized hi tindlela tin’wana, naswona ntsengo wuta hunguteka hiku ringanela.

3. Silika ya xirhendzevutani

Eka ku tiya ka le hansi ka ku rhendzeleka na ku tiya ka kahle ka slip, silica yitala kutirhisiwa tani hi filler naswona kutirhisiwa organosilane coupling agent. Ti silane coupling agents ta durha, naswona loko nhlayo yintsongo swinene ya silane coupling agent yinga tirhisiwa naswona matirhelo ya compound yanga cinci, ntsengo wa compound wunga hungutiwa swinene. Mukhuva lowu tolovelekeke iku tirhisa silica leyingana nhlayo yale henhla ya hydroxyl yale henhla, tani hileswi swikamberiweke kuva yi hlanganisiwa hiku olova. Xisweswo, hi mintlawa yotala ya hydroxyl eka compound, silane coupling agent yitsongo ya laveka naswona swivumbeko leswi fanaka swa michini swa hlayisiwa loko ntsengo wuhungutiwile.

4. Xigwitsirisi

Eka ti compounds to basa leti taleke hi TIO2, ti fillers tin’wana to basa ta ntsengo wale hansi (kufana na vumba lebyi hlantswiweke hi mati, calcium carbonate, whitening agent, na swin’wana) tinga tekiwa kuva ti siva yin’wana ya TIO2, naswona compound yahari na vuswikoti byokarhi byo funengeta xikan’we naku basa.

Eka ti silica filled tread compounds, ku cinca yin’wana ya 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 vutshunguri bya kuhisa eka maendlelo yo hlanganisa.

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

Hambi leswi density ya talc (2.7g/cm3) yinga yikulu kutlula ya carbon black (1.8g/cm3), loko kutirhisiwa 1.5 wa swiphemu (hi ntiko) swa talc 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, leswingata hunguta ntsengo lowunga kongomangiki.

5. Ku hungutiwa ka density

Swilo leswi endliweke hi rhaba hi ntolovelo swi xavisiwa hi mpimo ku nga ri hi ntiko. Loko u cinca formula ya rhaba kuva yi endla leswaku density yiva ehansi, loko urikarhi u hlayisa ntsengo hi unit volume wunga cinci, kutani unga hunguta ntsengo lowu nga kongomangiki. Xikombiso, hi ku cinca CR hi NBR, ntsengo hi yuniti ya vholumo ya rhaba ya hunguteka, ntsena loko ku cinca kun’wana eka rhaba ku nga tlheriseli endzhaku ku vuyeriwa loku ka ntsengo.

6. yi sivele ku hlanganisiwa ka magoza mambirhi hi ku hlanganisiwa ka swiengeteri.

Loko swi koteka, ku cinca ku hlanganisiwa ka magoza mambirhi hi ku hlanganisiwa ka magoza man’we hi ku tirhisa tithekiniki ta vulawuri bya eneji na ku kamberiwa ka eneji ya phurosese leyi tirhaka na swona swi nga hunguta ku durha.

7. Swipfuno swo lulamisa

Ku tirhisiwa ka swipfuno swo lulamisa swinga antswisa rivilo ra extrusion kumbe calendering ya compound, xisweswo swihunguta ku durha.

8. Ku hlanganisiwa ka FKM/ACM

Ku cinca FKM yo basa hi peroxide-cured FKM/ACM blend (Dai-El AG-1530) swinga endla leswaku rhaba yiva na kuhisa na mafurha yo antswa.
