Caag Nitrile ah waxaa lagu soo saaraa emulsion polymerization of butadiene iyo acrylonitrile.Caag Nitrile ah waxaa inta badan soo saara polymerization emulsion heerkulka hooseeya.Waxay leedahay iska caabin saliid oo heer sare ah, caabbinta xirashada sare, caabbinta kulaylka wanaagsan iyo adhesion xooggan..Khasaareheedu waa iska caabin heerkul hooseeya oo liita, caabbinta ozone liidata, sifooyinka korantada oo liita, iyo barti wax yar ka hooseeya.Rabadhka Nitrile waxaa inta badan loo isticmaalaa soo saarista alaabada caag u adkaysata saliidda.1) Hordhac Waxa kale oo loo yaqaan NBR.Caag synthetic ah oo ay soo saartay kobolymerization ee butadiene iyo acrylonitrile.Waa caag synthetic ah oo leh iska caabin saliideed oo wanaagsan (gaar ahaan saliidda alkane) iyo iska caabinta gabowga.Waxaa jira shan nooc oo ka kooban acrylonitrile (%) oo ku jira caagga nitrile: 42-46, 36-41, 31-35, 25-30, iyo 18-24.Inta badan maadada acrylonitrile, ayaa si fiican u caabbinta saliidda, laakiin iska caabbinta qabow ayaa hoos u dhigi doonta si waafaqsan.Waxa loo isticmaali karaa muddo dheer hawada 120°C ama saliidda 150°C.Intaa waxaa dheer, waxay sidoo kale leedahay iska caabin wanaagsan oo biyo ah, cidhiidhi hawo iyo waxqabadka isku xirnaanta oo aad u fiican.Si ballaaran loo isticmaalo soo saarista alaabooyin caag saliid u adkeysanaya oo kala duwan, gaasaska saliidda u adkeysa ee kala duwan, gaasaska, gacmaha, baakadaha dabacsan, tuubooyinka jilicsan, daabacaadda iyo rinjiyeynta caagagga, agabka caagga ah, iwm, waxayna noqdaan kuwo aan looga maarmin warshadaha sida baabuurta. , duulista, batroolka, iyo koobiyaynta walxaha laastikada.
1. Waxqabadka Nitrile caag waxa kale oo loo yaqaan caag butadiene-acrylonitrile, oo loo yaqaan NBR, oo leh celcelis miisaan kelli ah oo ku saabsan 700,000.Cad-cad ilaa iftiin jaale ah oo weyn ama budo leh, cufnaanta qaraabo 0.95-1.0.Rabadhka Nitrile wuxuu leeyahay iska caabin saliideed oo heer sare ah, ka labaad oo kaliya caag polysulfide ah iyo caagga fluorine, wuxuuna leeyahay iska caabin aad u fiican iyo cidhiidhi hawo.Khasaarada caagga nitrile waa in aysan u adkaysan karin ozone iyo caraf udgoon, hydrocarbons halogenated, ketones iyo ester dareerayaasha, sidaas darteed kuma haboona qalabka dahaadhka.Iska caabbinta kulaylku way ka fiican tahay kan styrene-butadiene caagga ah iyo neoprene, waxayna ku shaqeyn kartaa 120 ° C muddo dheer.Cidhiidhiga hawadu waa ka labaad oo kaliya ka butyl caag ah.Waxqabadka caagga nitrile waxaa saameeya waxa ku jira acrylonitrile.Marka maaddada acrylonitrile ay korodho, xoogga jilicsanaanta, caabbinta kulaylka, caabbinta saliidda, cidhiidhiga hawada iyo adkaanta ayaa kordha, laakiin barti iyo caabbinta qabow ayaa hoos u dhacda.Caag Nitrile ah ayaa leh iska caabbinta ozone liidata iyo guryaha dahaarka korantada, laakiin iska caabbinta biyaha wanaagsan.
Isticmaalka ugu muhiimsan ee Nitrile-ka waxaa inta badan loo isticmaalaa in lagu sameeyo wax soo saar saliida adkaysi u leh, sida tuubooyinka saliida u adkaysta, cajaladaha, caagagga diaphragms iyo bacaha saliidda ee waaweyn, iwm. giraanta, shaabadadaha saliidda, koobabka maqaarka, diaphragms, valves , gogosha, tuubada caagga ah, shaabadda, xumbo, iwm, ayaa sidoo kale loo isticmaalaa in lagu sameeyo go'yaal caag ah iyo qaybo u adkaysta.
3 Talooyin lagu hagaajinayo waxqabadka caabbinta saliidda nitrile: Iyadoo la kordhinayo nuxurka acrylonitrile, caabbinta saliidda waa la wanaajin karaa, laakiin iska caabbinta qabow ayaa hoos u dhigi doonta si waafaqsan.Waxa loo isticmaali karaa muddo dheer hawada 120°C ama saliidda 150°C.Intaa waxaa dheer, waxay sidoo kale leedahay iska caabin wanaagsan oo biyo ah, cidhiidhi hawada iyo waxqabadka isku xirnaanta ee wanaagsan.Si ballaaran loo isticmaalo soo saarista alaabooyin caag saliid u adkeysanaya oo kala duwan, gaasaska saliidda u adkeysa ee kala duwan, gaasaska, gacmaha, baakadaha dabacsan, tuubooyinka jilicsan, daabacaadda iyo rinjiyeynta caagagga, agabka caagga ah, iwm, waxayna noqdaan kuwo aan looga maarmin warshadaha sida baabuurta. , duulista, batroolka, iyo koobiyaynta walxaha laastikada.Iska caabin qabow oo la hagaajiyay iyo iska caabbinta heerkulka hooseeya: Nitrile caabbinta qabowgu way liidataa, caabbinta qabowguna way ka sii daraysaa korodhka maadada acrylonitrile.Adigoo isticmaalaya caag nitrile ah oo leh waxyaabo kala duwan oo acrylonitrile ah iyo hagaajinta isku-dhafka walxaha kala duwan ee ka-hortagga gabowga, wakiilada xoojinta iyo caagagga, caanaha caagga ah ee qabowga leh ee caabbinta saliidda wanaagsan iyo caabbinta daalka ayaa la heli karaa.
