Iipholima kubomi bethu bemihla ngemihla: irabha zokwenziwa

Namhlanje, iipholima ziyathandwa indawo ebaluleke kakhulu kubomi lonke uluntu. Zisetyenziswa kwiindawo ezininzi ezahlukileyo zobomi bethu bemihla ngemihla: wazikhulula iimpahla, izitya, izinto zokudlala moya, imijukujelwa, izithuthi. Ke kaloku omnye kakhulu umdla yaye kubalulekile ukuba inani iipropati eyahlukileyo i irabha zokwenziwa. Formula analogu zemvelo isakhiwo rhoqo, lo gama kwangaxeshanye, synthetic - rhoqo.

Ukuze kuveliswe Iipholima yolu hlobo ngendlela engazange mveliso baqalisa ngaphambi kweMfazwe Yehlabathi II eJamani naseRashiya. Butadiene irabha-sodium "Boone" yakhululwa eJamani. Kwaye ke kuqala kufuneka bavelise ngendlela engazange mveliso eRashiya polybutadiene. Zakhe bavelisa yi indlela butadiene anionic polymerization ulwelo eziphuhliswe Lebedev S.

Emva kwemfazwe, ngenxa yokunqongophala kwiimveliso zendalo, iintlobo zokwenziwa baqalisa ukuvelisa eUnited States. Ukususela ngelo xesha ukusa kolu khutsho mini izinto ezahlukeneyo, olusekelwe irabha zokwenziwa, kwakunye nazo zonke iimveliso irabha, unxulumene imveliso ngomlinganiselo omkhulu. Automotive, aerospace kunye eyama, ubunjineli, ulwakhiwo, ubunjineli yombane, amayeza, ishishini zezihlangu, iimpahla yabathengi - akukho nanye kwezi neefektri ayisekho ngaphandle Polymer ikhethekileyo. Loo ukusetyenziswa ngokubanzi kungenxa neseti Iimpawu zomzimba kunye ngomatshini yeentlobo ezahlukeneyo irabha kunye rubbers ezisekelwe phezu kwabo.

irabha Synthetic - yinto elastomer apho luthambe semvelo, ukumelana amanzi kunye nokuthintela ubushushu zombane iimpawu. Nokusetyenziswa kwenkqubo yokuhlanganisa Iipholima yolu hlobo unako-hlulwa ibe irabha kunye ebonite.

Zonke izixhobo polymeric kule klasi zihlelwa ngokungqinelana yesicelo iintsini yenjongo ekhethekileyo kunye jikelele. irabha Synthetic injongo jikelele - yenye esibonakala ngeempawu ezintsonkothileyo zobugcisa kakhulu (bhetyebhetye, amandla, nokuqina kwayo, kunye nabanye.). rubbers injongo jikelele zisetyenziswa ngempumelelo uluhlu olubanzi iimveliso yemveliso mass, ikakhulu ngenxa amavili. Apha ziquka butadiene, butadiene-methylstyrene, rubbers isoprene, kunye isobutylene-isoprene copolymer (butyl zerabha).

irabha Synthetic kusoloko injongo eyodwa okanye ezahlukeneyo uphawu eziliqela unique leyo inika iimfuno ezikhethekileyo eliphezulu-grade ngomsebenzi wemveliso phantsi kweemeko ezinzima. Hi xikombiso, le zilahlwe Yinto eyaziwa ioli yalo phezulu nepetroli ezingatshiyo. Fluorinated - elibalaseleyo kunye gasket kunye nozinzo high thermal (200 ° C). Kwakhona eyaziwa irabha polysulfide zokwenziwa, vinylpyridine, urethanes, kunye nezinye isobutylene halogenated.

Ngaphandle kolu neyantlukwano izinto polymeric kwi isakhiwo neempawu, ukuza kuthi ga ngoku, uphuhliso liqhubeka ngale ndawo, ukuze nibe nako ukuhlangabezana neemfuno olukhula abathengi ezahlukeneyo kwiindawo ezahlukeneyo.
