Polymers a rayuwar yau da kullum: roba roba

Yau, roba polymers zauna wani muhimmin matsayi a cikin rayuwar mutane. Suna amfani da dama daban-daban na yankunan da rayuwar yau da kullum: daga tufafi, jita-jita, toys zuwa jirgin sama, makamai masu linzami, motocin. Kuma daya daga cikin mafi ban sha'awa da kuma muhimmanci ga mai yawan musamman Properties ne wani roba roba. Formula halitta analogue yana da wani yau da kullum da tsarin, yayin da a lokaci guda, roba - sababbu.

Don samar da polymers na da irin wannan a kan wani m sikelin fara jim kadan kafin yakin duniya na II a Jamus da kuma Rasha. Butadiene roba-sodium "Boone" saki a Jamus. Kuma na farko da za a samar a kan masana'antu sikelin a Rasha polybutadiene. Ya samar da hanyar da anionic Polymerization ruwa butadiene ɓullo da Lebedev S.

Bayan da yaki, saboda rashin halitta kayayyakin, roba nau'in fara nuna a Amurka. Daga wannan lokaci zuwa wannan rana saki daban-daban kayan, tushen roba roba, kazalika da dukan roba kayayyakin, shi da dangantaka da wani babban-sikelin samar. Automotive, Aerospace da kuma jirgin sama, aikin injiniya, yi, lantarki injiniya, magani, takalma masana'antu, kayayyakin - babu wani daga wadannan masana'antu za su wanzu ba tare da wannan musamman polymer. Irin wannan tartsatsi amfani ne saboda da sa na musamman da jiki da kuma inji halaye na iri daban-daban roba da kuma rubbers dangane da su.

Roba roba - shi ne wani elastomer ga wanda muhimmi elasticity, ruwa juriya da kuma lantarki rufi Properties. Tare da yin amfani da vulcanization aiwatar polymers na da irin wannan za a iya sarrafa a cikin roba da kuma ebonite.

All polymeric kayan da wannan aji suna classified bisa ga aikace-aikace a kan gumis na musamman da kuma janar manufa. Roba roba general manufa - shi ne daya wanda aka halin hadaddun sosai fasaha Properties (sassauci, ƙarfi, karko, da sauransu.). janar nufi rubbers an samu nasarar yi amfani ga mai fadi da kewayon kayayyakin na taro samar, da farko don tayoyin. Ga hada butadiene, butadiene-methylstyrene, isoprene rubbers, kuma isobutylene-isoprene copolymer (butyl roba).

Roba roba ne ko da yaushe wata manufa ta musamman, ko da dama daban-daban daya musamman alama cewa samar da wata high-sa musamman bukatun ga samfurin yi a matsananci yanayi. Alal misali, nitrile An sani ga ta high man fetur da kuma man fetur din-resistant. Fluorinated - yake da kyau kwarai da kuma gaskets tare da high thermal kwanciyar hankali (200 ° C). Kuma aka sani da polysulfide roba roba, vinylpyridine, urethanes, da kuma sauran halogenated isobutylene.

Duk da wannan bambancin da polymeric kayan a kan tsarin da kaddarorin, to date, da cin ci gaba a cikin wannan yankin, don su iya saduwa da kullum girma bukatar daban-daban abokan ciniki a fagage daban-daban.
