Macluumaadka Alaabta

Rubber Nitrile waxaa inta badan loo isticmaalaa soo saarista alaabada caag u adkaysata saliidda

shaabadihii NBR, oo sidoo kale loo yaqaan shaabadihii Nitrile. NBR waxaa laga sameeyay butadiene iyo acrylonitrile iyadoo la adeegsanayo emulsion polymerization. NBR waxaa inta badan soo saara habka polymerization emulsion heerkulka hooseeya, kaas oo leh caabbinta saliid aad u fiican, caabbinta abrasion sare, caabbinta kulaylka wanaagsan iyo xoog koollada adag. Khasaareheedu waa iska caabin heerkul hooseeya oo liita, caabbinta ozone liidata, sifooyinka dahaarka liidata, dabacsanaanta wax yar ka hooseeya. Rabadhka Nitrile waxaa inta badan loo isticmaalaa soo saarista alaabada caag u adkaysata saliidda. Waxaa loo soo gaabiyaa NBR, waa caag synthetic ah oo lagu sameeyay kobolymerization butadiene iyo acrylonitrile. Waa caag synthetic ah oo leh iska caabin saliideed oo wanaagsan (gaar ahaan saliidda alkane) iyo iska caabinta gabowga. Maadada akrilonitrile (%) ee NBR waa 42-46, 36-41, 31-35, 25-30, 18-24 iyo wixii la mid ah. Inta badan maadada acrylonitrile, ayaa si fiican u caabbinta saliidda, laakiin caabbinta qabowgu hoos ayey u dhacdaa. Waxaa lagu isticmaali karaa hawada 120 ℃ ama saliid at 150 ℃ muddo dheer. Intaa waxaa dheer, waxay leedahay iska caabin wanaagsan oo biyo ah, xajin iyo sifooyin isku xiran oo aad u fiican. Si ballaaran loo isticmaalo wax soo saarka noocyo kala duwan oo saliid ah oo caag ah, noocyo kala duwan oo gaasaska u adkaysta saliidda, gaskets, daasadaha, baakadaha dabacsan, tuubada dabacsan, daabacaadda iyo rinjiyeynta caag, qalabka caag cable, iwm

Xirmooyinka NBR waxay leeyihiin iska caabin saliid oo heer sare ah. monomers NBR waxaa loo qaybin karaa saddex qaab-dhismeedka silsiladaha kala duwan: cis, trans iyo 1,2-yaki. Qaab dhismeedka NBR ee caadiga ah waa qiyaastii 78% trans. Sababtoo ah joogitaanka kooxaha cyano ee qaabka silsiladda kelli ee NBR, iska caabbinta saliidda (tusaale ahaan saliidaha macdanta, shidaalka dareeraha ah, saliidaha xoolaha iyo khudradda iyo dareerayaasha) waxay ka sarreeyaan caag dabiici ah, neoprene iyo styrene butadiene caag. Marka la barbardhigo caagadaha kale, NBR waxay leedahay heerkul adeeg oo ballaaran, heerkulka adeegga muddada-dheer waa 120oC, isla mar ahaantaana, NBR waxay leedahay iska caabin heerkul hooseeya oo wanaagsan, heerkulka kala-guurka dhalada ugu hooseeya wuxuu gaari karaa -55 ℃.

Macluumaadka shirkadda

Waxyaalaha ay shirkadu soo dajiso ama dhoofiso waxa ka mid ah.

（ 1 ） Catalysts and Auxiliaries ： Katalistuhu waa qaybta firfircoon ee runtii u shaqeysa sida kicinta oo yaraynaysa tamarta firfircoonida ee falcelinta. Waxyaalaha lagu daro, dhinaca kale, waa qaybo kaabayaal ah, ama wax-ku-darka qaab-dhismeedka ama qalabka elektarooniga ah, kuwaas oo hagaajin kara xasiloonida kicinta, halka kuwa elektaroonigga ah ay wax ka bedeli karaan sifooyinka elektaroonigga ah ee kicinta .

( 2 ) Polymers: Polymerization waa habka ay unugyada soo noqnoqda ee ka samaysan polymer ay isku xiran yihiin curaarta covalent. Polymers waxay ka jiri karaan dawlado kala duwan iyadoo ku xiran marxaladda, qaabka iyo habaynta silsiladahooda molecular. Labada dawladood ee ugu waaweyn waa amorphous iyo crystalline. Polymers inta badan waxay ku jiraan qaab semi-crystalline ah kaas oo wejiyada amorphous iyo crystalline ay wada nool yihiin.
