Iyini Irabha Yokwenziwa?

Incazelo

Irabha yokwenziwa  yenziwa abantu, ayitholakali emvelweni. Isebenza kakhulu njengerabha yemvelo. Lezi zinto zibizwa ngokuthi ama-elastomers ngoba angakwazi ukwelula futhi abuyele esimweni sawo. Izimboni zenza ama-elastomers zisebenzisa amakhemikhali avela kuwoyela. Irabha yokwenziwa ifana kakhulu nerabha yemvelo, kodwa ingashintshwa ukuze kwenziwe imisebenzi ekhethekile.

Qaphela: Kunezinhlobo eziningi zerabha yokwenziwa, njengerabha ye-styrene-butadiene, irabha ye-butyl, nerabha ye-silicone. Uhlobo ngalunye lunamandla ngendlela yalo futhi lusetshenziselwa izinto ezahlukene.

Imboni yamakhemikhali ithi irabha yokwenziwa yinoma iyiphi i-elastomer engavuthwa futhi yenziwa ngokuhlanganisa amakhemikhali ndawonye. Leli qembu linamarubha e-acrylate, ama-butadiene-styrene copolymers, amarabha e-nitrile-butadiene, nokunye. Lawa ma-elastomer abalulekile ekwenzeni amathayi, izimvu zamanzi, amapayipi nezinye izinto eziningi.

Ukukhiqiza

Ukwenza irabha yokwenziwa kuqala ngezinto ezenziwe ngamafutha. Izimboni zisebenzisa izinto ezifana ne-naphtha, ehlangana negesi yemvelo ukwenza ama-monomer. Ama-monomers yizinto ezifana ne-butadiene, i-styrene, i-isoprene, i-chloroprene, i-acrylonitrile, i-ethylene ne-propylene. I-Polymerization inqubo ehlanganisa ama-monomers ukwenza amaketanga amade abizwa ngokuthi ama-polymers.

• Ama-elastomer amaningi anomgogodla owenziwe nge-athomu ye-carbon, kodwa irabha ye-silicone inomgogodla owenziwe nge-silicon nomoya-mpilo.

• Irabha ye-Silicone ivela ku-silicon, etholakala esihlabathini noma ku-quartz.

Ama-catalyst ahlukene namamiksi e-monomer asiza ukulawula ukuthi ama-elastomer aphuma kanjani. Ngemuva kwe-polymerization, i-material ihamba nge-vulcanization. Lesi sinyathelo sisebenzisa izinto ezifana nesibabule ukwenza irabha ibe lukhuni futhi ibe namandla. Ukushintsha ukwakheka kwamakhemikhali kuvumela amafekthri enze ama-elastomers ukuze asetshenziswe okuningi okukhethekile.

FAQ

Uyini umehluko omkhulu phakathi kwerabha yemvelo kanye neyokwenziwa?

Irabha yemvelo ivela ezihlahleni. Irabha yokwenziwa yenziwa ezimbonini ngamakhemikhali kawoyela. Irabha yokwenziwa ingashintshwa ukuze kwenziwe imisebenzi ekhethekile. Zombili izinhlobo zingakwazi ukwelula futhi zibuyele esimweni sazo. Irabha yokwenziwa ngokuvamile ihlala isikhathi eside ezindaweni eziqinile.

Iyiphi irabha yokwenziwa esebenza kangcono emathayini emoto?

Irabha ye-styrene-butadiene (SBR) ne-butadiene rubber (BR) ingcono kakhulu kumasondo emoto. Awagugi ngokushesha futhi angathatha ukushisa. Abenzi bamathayi baxuba i-SBR nerabha yemvelo ukwenza amathayi aqine futhi ahlale isikhathi eside.

Ingabe irabha yokwenziwa ingagaywa kabusha?

Yebo, izinhlobo eziningi zerabha zokwenziwa zingagaywa kabusha. I-Santoprene kulula ukuyigaya kabusha. Ukugaywa kabusha kusiza ukunciphisa udoti futhi konga izinto. Enye irabha egaywe kabusha isetshenziselwa izingxenye zemoto ezintsha, phansi, noma izinkundla zokudlala.

Kungani amanye amarabha amelana namafutha namakhemikhali kangcono kunamanye?

I-Nitrile (NBR) ne-fluorocarbon (Viton) zinezimonyo zamakhemikhali ezikhethekile. Lezi zivimba uwoyela namakhemikhali ukuthi angalimazi irabha. Yingakho zilungele izinja zamanzi, amapayipi kanye namagesi ezinjinini nasezimbonini.

Ingabe irabha ye-silicone iphephile ekudleni nasekusetshenzisweni kwezokwelapha?

Yebo, irabha ye-silicone  iphephile ekudleni nasezintweni zezokwelapha. Ayisabeli kumakhemikhali amaningi futhi ingathatha ukushisa okuphezulu. Izibhedlela zisebenzisa i-silicone ukwenza amashubhu nezimila. Abenzi bokudla bayisebenzisela omata bokubhaka namathuluzi asekhishini.
