1, caagga nitrile
Tooska 'Solonoid' ayaa laga sameeyaa polumlerization emulsion ah ee badhanka 'Budienne iyo acrylonitrile', badiyaa waxay ka kooban yihiin polummeration polymoion heer kul ah. Waxay leedahay iska caabbinta saliida saliida, caabbinta wanaagsan, iska caabin kulayl wanaagsan iyo adhesion adag. Faa'iido darrooyinka ayaa ah iska caabbinta heerkulka hooseeya ee liidata, iska caabbinta ozone ee saboolka ah, waxqabadka korantada ee liita, iyo wax yar oo jilicsan.
Intaas waxaa sii dheer, waxay sidoo kale leedahay iska caabbinta biyaha wanaagsan, hawada hawada iyo waxqabadka adhesion wanaagsan. Waxaa si weyn loogu isticmaalaa soo saarista alaabada caagga ah ee caagga ah ee saliida leh, gaskooyin kaladuwan, garka, xirxiran, daabacaado, oo ay ku noqdeen qalab muhiim ah oo gawaarida ah, duulista, batroolka, koobiyeynta, elektiroonigga ah iyo warshadaha kale. Warshadaha kale.
NIITRIE RAP (NBR) waxay leedahay iska caabbinta saliida saliida, labaad oo keliya polesulfide caag iyo fluororrubber, oo leh caabbinta caabbinta iyo cirifka hawada. Faa'iido darrada ah ee NBR-da ayaa ah in aysan u adkaysan waayo ozone iyo udgoon oo loo yaqaan 'hydrocarbon', hayo hydrocarbon, ketone iyo xargaha solther-ka, sidaa darteed kuma haboona kharashka qalabka.
Isticmaalka ugu weyn
2, caag EPDM
EPDM waa EPDM-ka ee Ethylem oo ah Etholty, Propylene iyo Dien-ka oo aan kala go 'lahayn. Waxay ganacsiga ahayd sanadkii 1963. Dunidu waxay isticmaashay 800000 tan sanadkii. Astaamaha ugu weyn ee EPDM waa iska caabin aad u fiican, iska caabbinta ozone iyo iska caabbinta. EPDM waxaa iska leh polyolman oo leh wax qabad aad u wanaagsan. Ethylene Propylene Dieneomer (EPDM) ayaa leh saamiga ugu hooseeya ee dhammaan daaqadaha. Waxay nuugi kartaa wax badan oo buufin iyo saliid, oo saameyn yar ku yeeshaan wax qabadkeeda. Sidaa darteed, xeryahooda caagga ah ee qiimaha jaban ayaa la soo saari karaa.
Qaab dhismeedka molika iyo guryaha
Qaab dhismeedka: Etherene Propylement Terpolymer waa Terpolmyer of Ethpolmener of Ethylemene, Propylene iyo Diene-ga aan lagaraneyn. Dienes waxay leeyihiin qaab dhismeed gaar ah. Kaliya mid ka mid ah labada xiddig ayaa laga yaabaa in lagu codeeyo. Bond oo aan la-darin labajibbaaranaha ayaa inta badan loo isticmaalaa sida wakiilka iskutallaabta ah. Polymer kale oo aan fiicnayn ma aha silsilad muhiim ah, laakiin silsilad dhinaca ah. Silsiladda ugu weyn ee EPDM gabi ahaanba waa buuxsamay. Hantidan ayaa ka dhigaysa kuleylka EPDM inuu u adkaysto, iftiinka iska caabinta, oksijiinta u adkaysta, gaar ahaan ozone u adkaysta. Ethylenene Propylement Terpolyer waa aasaaska aan tooska ahayn, u adkaysata xalka loo yaqaan 'pour iyo kiimikooyin, nuugista biyaha hooseysa iyo waxqabadka xiidmaha.
Tilmaamaha: 1. Guryaha korantada; 2. Checksity; 3. Xadgudubka; 4. Cufnaanta hoose iyo buuxinta sare; 5. Cadaadiska superhaater; 6. Biyaha uumiga uumiga; 7. Ka hortag {{{7 {7 {7 {7 {7 {7 {7 {7 {7 {7- hantida gaboobaya; 8. Cadaadiska iska caabbinta.
3, fluororurubber (fkm)
Waxaa jira noocyo kala duwan oo fluorinine {{0} oo ay ku jiraan baqdin ku dhaca molecules iyadoo loo eegayo nuxurka kaladuwan ee kaladuwan, oo ah qaab dhismeedka monomer. Waqtigan xaadirka ah, fluororrober ka kooban nidaamka hexafluoride waa markii ugu horreysay ee lagu taxay magaca "fluororubber". Cadaadiska heerkulka sare ayaa ka wanaagsan caalada silicone. Waxay leedahay iska caabbinta kiimikada wanaagsan, iska caabbinta saliidaha iyo dareeraha badankood (marka laga reebo ketones iyo esters-ka), iska caabin cimilo wanaagsan iyo iska caabin cimilo oo wanaagsan, laakiin iska caabin qabow, laakiin iska caabin daran. Waxaa si weyn loogu isticmaalaa saldhigga, B iyo alaabada kale, iyo shaabadaha dhirta kiimikada, iyadoo heerkulka adeegga uu u dhexeeyo {{4}- 20 shahaadada ilaa 260 darajo. Marka uu jiro bedel heer iskiis ah u adkeysta, waxaa lagu dabaqi karaa - 40 laakiin qiimaha ma fiicna. Sare.
