Polymers in our nolol maalmeedka: caag synthetic

Maanta, polymers dardaro mashquulin meel aad u muhiim ah nolosha aadanaha oo dhan. Waxay waxaa loo isticmaalaa meelo badan oo kala duwan oo ka mid ah nolol maalmeedka, dharka, suxuunta, alaabta lagu ciyaaro in diyaaradaha, gantaalada, baabuurta. Oo mid ka mid ah ugu xiisaha badan oo muhiim u ah tiro ka mid ah sifooyin u gaar ah waa caag ah synthetic. Formula analoogga dabiiciga ah uu leeyahay qaab-dhismeedka si joogto ah, halka isku mar ah, isku dardaro - aan joogto ahayn.

Si loo soo saaro polymers noocan ah heer warshadeed yar ka bilaabeen ka hor dagaalkii labaad ee adduunka ee Germany iyo Russia. Butadiene caag-sodium "Boone" daayay in Germany. Oo kii hore si loo soo saaray heer warshadeed ee Russia polybutadiene. Uu soo saaray habka of butadiene dareere polymerization anionic horumariyo Lebedev S.

dagaalka, ay sabab u la'aan alaabta dabiiciga ah ka dib markii, noocyada dardaro bilaabeen in ay soo saaraan oo dalka Mareykanka ah. Xilligaas wixii ka war maanta ka mid ah maaddooyinka kala duwan, caag synthetic ku salaysan, iyo sidoo kale dhammaan waxyaabaha caag, taas oo la xiriirta wax soo saarka oo baaxad weyn oo ah. Automotive, aerospace iyo duulista, injineernimada, dhismaha, injineernimada korontada, daawo, warshadaha kabaha, alaabta macaamiisha - midkoodna warshadaha kuwan ma jiri karaan oo aan polymer this gaar ah. isticmaalka baahsan noocan oo kale ah waxaa sabab u ah set gaarka ah ee astaamaha jirka iyo farsamo ee noocyada kala duwan ee caag iyo masaxado ku salaysan iyaga on.

caag dardaro - waa elastomer ah oo guryaha barti soo jireenka ah, iska caabin biyaha iyo korontada madhxiya. Iyadoo la isticmaalayo mid ah polymers habka vulcanization noocan ah loo hawl gelin caag iyo ebonite karo.

All qalabka polymeric of class this waxaa loo kala saaraa sida uu codsiga on ciridka ujeedada gaarka ah iyo guud. Ujeedada guud caag dardaro - waa mid ka mid kaas oo ah waxa lagu gartaa guryaha adag sare farsamo (dabacsanaan, xoog, cimri, iyo kuwa kale.). masaxado Ujeedada guud waxaa si guul leh loo isticmaalo tiro balaadhan oo ah wax soo saarka ee wax soo saarka mass, ugu horayn loogu talagalay taayirrada. Halkan ka mid ah butadiene, butadiene-methylstyrene, masaxado isoprene, iyo acetate isobutylene-isoprene (caag butyl).

caag dardaro had iyo jeer waa ujeeddo gaar ah ama kala duwan ka mid ah feature gaar ah oo bixiya a shuruudo gaar ah qaab wax soo saarka yihiin xaalado adag oo fasal sare. Tusaale ahaan, nitrile ah Waxaa la og yahay in ay saliid sare oo shidaal u adkaysta. Fluorinated - waa heer sare ah oo gaskets la xasiloonida kaamerada sare (200 ° C). Sidoo kale loo yaqaan caag polysulfide dardaro, vinylpyridine, urethanes, iyo isobutylene kale halogenated.

Inkastoo ay kala duwan this qalabka polymeric on qaabka iyo guryaha, taariikhda, horumarinta sii aagga this, si ay u awoodaan si ay u daboolaan baahida sii kordhaysa ee macaamiisha kala duwan meelaha kala duwan.
