Kungani i-helcanization ibalulekile?

Ukuqalisa

I-Rubber Vulcanization inqubo yegumbi embonini yerabha, eguqula irabha eluhlaza ibe yinto eqinile, elastikiza elungele ukusetshenziswa okuhlukahlukene kwezicelo. Le nqubo yamakhemikhali, ehilela ukufaka isibabule noma amanye ama-curful kurabha eluhlaza, ikhulisa kakhulu izakhiwo zayo zemishini, ukumelana nokushisa, kanye nokuqina. Ukubaluleka kwe-Vulcanization akunakweqiwa ngokweqile, njengoba kunciphisa ukukhiqizwa kwemikhiqizo engenakubalwa yansuku zonke, kusuka kumathayi ezimoto kuya ezinhlakeni zezimboni. Kulabo abanentshisekelo kwizicelo ezibanzi ze Irabha , ukuqonda iqhaza le-Vuvanization kubalulekile. Le ndatshana idlulela kwisayensi, umlando, kanye nokubaluleka kwezimboni zeRubber Vulcanization, enikeza umthelela ophelele womthelela wawo ekukhiqizweni kwanamuhla.

Isayensi ngemuva kobungozi benjoloba

Kuyini ubuvimbi?

I-Vulcanization yinqubo yamakhemikhali ehilela ukungezwa kwesibabule noma ezinye izindlela ezifundwayo enjoloba eluhlaza. Le nqubo idala izixhumanisi zokuwela phakathi kwamaketanga we-polymer, okuholela ekusetshenzisweni okuningana okuthe xaxa, okuhlala isikhathi eside, kanye nokumelana nezici zezemvelo. Izinga le-Vulcanization lingalawulwa ukuze kufinyelelwe izakhiwo ezibonakalayo ezithile, okwenza kube yindlela eguquguqukayo yezinhlelo zokusebenza ezahlukahlukene zezimboni.

Ukusabela kwamakhemikhali abathintekayo

Inqubo ye-Vulcan ngokuyinhloko ifaka ukwakheka kwesiphambano se-sulfure phakathi kwamaketanga amade we-polymer enjoloba. Lezi zixhumanisi ze-cross zidalwe ngochungechunge lokuphendula kwamakhemikhali, okubandakanya ukwengeza, ukufaka esikhundleni, kanye nokuphendula okuqedisweni. Ukuba khona kwama-accelerator kanye nezishoshovu kungasheshisa kakhulu lokhu kusabela, okuvumela izinqubo ezisebenza kahle zokukhiqiza.

Izinhlobo ze-Vulcanization

Kunezinhlobo eziningi zezinqubo ze-vulcanization, ngamunye ofanelekile ngezicelo ezihlukile:

• I-Vulcanization evamile: Isebenzisa isibabule kanye nama-accelerator ukudala inethiwekhi elinganiselayo yezixhumanisi ze-cross.

• I-Peroxide Vulcanization: Isebenzisa i-organic peroxides ngezinhlelo zokusebenza ezidinga ukumelana okuphezulu.

• I-Radiation Vulcanization: Isebenzisa imisebe yamandla aphezulu ukwakha izixhumanisi zokuwela, ezivame ukusetshenziswa kwezimboni zezokwelapha nakwa-Aerospace.

Umongo womlando we-Vulcanization

Ukutholwa kwe-Vulcanization

Inqubo yokuvukelwa kwatholakala nguCharles Goodyear ngo-1839. Kwenzeke ukutholwa ngengozi kukaGoodyear lapho ephonswa ingxube yenjoloba kanye nesibabule esitofini esishisayo, okuholela ekushintsheni kwezinga lokushisa. Lokhu kuhlanekezela kuguqulwe imboni yerabha, ibeka isisekelo sezicelo zanamuhla.

Ukuziphendukela kwemvelo kwamasu we-vulcanization

Eminyakeni edlule, amasu we-Vulcanization aqhamuke ahlangabezana nezidingo zezimboni ezahlukahlukene. Ukwethulwa kwama-accelerator ekuqaleni kwekhulu lama-20 kuncishise izikhathi zokwelapha, kanti ukuthuthuka kwanamuhla kugxile ezindleleni ezinobungane nezisebenzayo, njengokuvuselela kwemisebe nokuvuselelwa kwemisebe nokuvuselelwa kwemisebe kanye nokuvuselelwa kwemisebe kanye nokuvuselelwa kwemisebe.

Izicelo zezimboni zenjoloba evulungiswazini

Imboni yezimoto

Umkhakha wezimoto ungomunye wabathengi abakhulu kakhulu benjoloba evundlekeni. Amathayi, izimpawu, ama-hoses, namabhande akhiqizwa wonke athola i-vulcanized ruble, enikeza ukuqina okudingekayo kanye nokuqina kwezicelo eziphezulu zokusebenza. Amandla okubekezelela amazinga okushisa aphezulu kanye nokucindezelwa okwenziwe ngomshini kwenza i-ruble ye-vulban ebabazekayo kulo mkhakha.

Ukwakha kanye nengqalasizinda

Ezokwakha, i-rucber evundile isetshenziselwa izinto zophahla, ulwelwesi olungenamanzi, kanye nama-vibration isolate Parts. Ukumelana kwayo kwezici zezemvelo ezifana nemisebe ye-UV ne-Ozone kuqinisekisa ukusebenza okuhlala isikhathi eside ezimeni ezinzima.

Ezokwelapha nezempilo

Imboni yezokwelapha ithembela kwinjoloba evundile yemikhiqizo efana namagilavu ​​okuhlinza, ama-catheters kanye nezimpawu. I-Biocompitive Ebonakalayo kanye nokumelana nezinqubo zokunyusa zenza ilungele izinhlelo zezokwelapha.

Izinselelo nezinkomba zesikhathi esizayo

Ukukhathazeka kwemvelo

Enye yezinselelo eziyinhloko ebhekene nomkhakha werabha umthelela wezemvelo we-Vulkan. Izindlela zendabuko zivame ukubandakanya ukusetshenziswa kwamakhemikhali anobuthi futhi akhiqize imfucuza. Abaphenyi bahlola ezinye izindlela ezizinzileyo, ezinjenge-curchives esekelwe kwi-bio kanye nobuchwepheshe bokuphinda usebenzise kabusha, ukubhekana nalokhu okukhathazayo.

Ubuchwepheshe ubuchwepheshe

Intuthuko nge-nanotechnology kanye nesayensi yezinto ezibonakalayo ibheka indlela yamasu amasha we-vulcanization. Isibonelo, ukufakwa kwama-nanoparticles kungakhulisa izakhiwo zemishini zenjoloba evundlekeni, ukuvula amathuba amasha ezicelo eziphezulu zokusebenza.

Ukugcina

I-Rubber Vulcanization inqubo eguqukayo eye yakha izimboni zanamuhla nobuchwepheshe. Ukusuka ekutholweni kwayo nguCharles Goodyear kwizicelo zayo zamanje ezezinhlelo zokusebenza zezimoto, zokwakha, kanye nezempilo, ukugqugquzela ubuvikeleli kuyaqhubeka ukuba yitshe lesitshe lesayensi. Njengoba imboni iqhubekela phambili kokusimama, izinto ezintsha kumasu wokuvuselela athembisa ukubhekana nezinselelo zemvelo ngenkathi kuthuthukisa ukusebenza kwezinto ezibonakalayo. Ngokuqonda okujulile kwendima ye Irabha ezimbonini ezahlukahlukene, ucwaningo oluqhubekayo nentuthuko kuhlala kubalulekile.
