Tilmaamaha iyo shaxda waxqabadka ee Rubber Nitrile

Sharaxaad faahfaahsan oo ku saabsan sifooyinka caagga nitrile

Rabadhka Nitrile waa copolymer of butadiene iyo acrylonitrile, iyo isku darka acrylonitrile ka kooban yahay saamayn weyn oo ku sifooyinkiisa farsamada, sifooyinka koollada, iyo caabbinta kulaylka.Marka la eego sifooyinka butadiene iyo acrylonitrile monomers, butadiene waxa uu leeyahay polarity daciif ah, halka acrylonitrile uu leeyahay polarity ka xoog badan.Sidaa darteed, nuxurka acrylonitrile badan ee silsiladda ugu weyn ee caagga nitrile, ayaa ka sii daraya dabacsanaanta silsiladda ugu weyn.Heerkulka jaban ee heerkulka hooseeya, ayaa ka sii daraya waxqabadka iska caabbinta heerkulka hooseeya;Dhanka kale, acrylonitrile waxay leedahay caabbinta kulaylka wanaagsan sababtoo ah inta lagu jiro habka kuleylka, acrylonitrile ee caagga nitrile wuxuu dhalin karaa walxo alkohol ah si loo xakameeyo hoos u dhaca kuleylka.Sidaa darteed, caabbinta kulaylka caagga nitrile waxay kordhisaa kororka maadada acrylonitrile;Dhanka kale, sababta oo ah qodobka polarity ee acrylonitrile, kordhinta maadada acrylonitrile waxay hagaajin kartaa xoogga koollada ee caag nitrile.Sidaa darteed, aad bay muhiim u tahay in la tijaabiyo waxa ku jira acrylonitrile xidhan ee ku jira caag nitrile ah.

Maaddada acrylonitrile waxay saameyn weyn ku leedahay waxqabadka NBR.Maaddada acrylonitrile ee caagga guud ee acrylonitrile nitrile waa inta u dhaxaysa 15% iyo 50%.Haddii maadada acrylonitrile ay kor u kacdo in ka badan 60%, way adkaan doontaa, oo la mid ah maqaar, oo ma yeelan doonto hanti caag ah.

1. Oil caabbinta iyo caabbinta dareeraha: Nitrile caag saliideed caag caadi ah.Caag Nitrile ah ayaa aad uga adkeysi badan saliidaha ku saleysan batroolka, benzene, iyo dareerayaasha kale ee aan polar-ka ahayn marka loo eego caagga dabiiciga ah, caagga styrene butadiene, rubber butyl, iyo caagyada kale ee aan cirifka ahayn, laakiin sidoo kale way ka fiican tahay caag koloriin leh.Si kastaba ha noqotee, caagga nitrile wuxuu leeyahay caabbinta liidata ee saliidaha polar iyo dareerayaasha (sida ethanol), laakiin caabbinta liidata ee caagga aan cirridka ahayn.

2. Sifooyinka waxqabadka jirka: Nitrile rubber waa qaab-dhismeed random ah oo ka kooban nitrile copolymers oo aan ku kicin xiisad.Sidaa darteed, sifooyinka jireed iyo farsamada ee caagga nitrile saafiga ah ee vulcanized ah waxay la mid yihiin kuwa caagga nitrile ee styrene, oo aad uga hooseeya caagga dabiiciga ah.Ka dib marka lagu daro buuxinta xoojinaya sida kaarboon madow iyo resin phenolic, xoogga xajinta caagga nitrile vulcanized waxay gaari kartaa heerka caagga dabiiciga ah, badiyaa agagaarka 24.50mpa.Marka maaddada polarity ee NBR ay korodho, dabacsanaanta silsiladda makromolecular ayaa hoos u dhacda, xoogga atomigga ee u dhexeeya molecules ayaa kordha, bonds double hoos u dhaca, iyo silsiladda macromolecular aan saturated, taasoo keentay in taxane ah oo isbedel waxqabadka.Marka nuxurka ACN uu u dhexeeyo 35% iyo 40%, waa barta muhiimka ah ee qallafsanaanta, barti, iyo engegnaanta 75 ℃.Haddii caabbinta saliiddu ay buuxiso shuruudaha, noocyo leh ACN ka yar 40% waa in la isticmaalo inta ugu badan ee suurtogalka ah.Balaastinimada caagga nitrile waa ka yar yahay caagga dabiiciga ah iyo caagga butadiene ee styrene.Laatignimada NBR waxay si dhow ula xiriirtaa heerkulka.Marka la barbar dhigo NBR, suurtagalnimada heerkulka iyo kororka barti waa weyn tahay.Sidaa darteed, caag nitrile ah ayaa aad ugu habboon wax soo saarka shoogga oo leh caabbinta saliidda sare.Astaamaha barti ee caag nitrile ah oo isbeddelaya iyada oo la isku xidho acrylonitrile

3. Neefsashada: Nitrile-ka caagga ah waxa uu leeyahay cidhiidhi hawo fiican marka loo eego caagga dabiiciga ah iyo styrene butadiene, laakiin uma fiicna sida caagga polysulfide, kaas oo la mid ah caagga butyl-ka.

4. Waxqabadka heerkulka hooseeya: caag Nitrile ah ayaa leh wax qabad heerkul hoose oo liita ee caagga guud.Waxqabadka heerkulka hooseeya wuxuu la xiriiraa nuxurka acrylonitrile, iyo heerkulka kala-guurka muraayadda wuxuu kordhiyaa kororka maadada acrylonitrile.Waxay yarayn kartaa heerkulka kala-guurka dhalada ee caagga nitrile waxayna hagaajin kartaa waxqabadkeeda heerkulka hooseeya.

6Adiga oo dooranaya caanaha ku habboon, alaabada caagga nitrile waxaa loo isticmaali karaa si joogto ah 120 ℃;Waxay u adkeysan kartaa saliid kulul at 150 ℃;Ka dib markii lagu qooyay saliid at 191 ℃ 70 saacadood, weli waxay leedahay awood ay ku laabato.6. Ozone caabbinta: Nitrile caabbinta ozone-ka ayaa liidata waxaana guud ahaan lagu wanaajiyaa iyada oo lagu daro walxaha u adkaysta ozone.Si kastaba ha ahaatee, alaabooyinka la soo xidhiidha saliidda marka la isticmaalayo waxay u nugul yihiin inay ka saaraan wakiilka u adkaysta ozone waxayna luminayaan caabbinta ozone.Marka lagu daro PVC, saameyntu waa mid muhiim ah.

7. Biyo caabbinta: caag Nitrile ah ayaa iska caabbinta biyaha ka fiican leh.Mar kasta oo ay ka kooban tahay acrylonitrile, ayaa ka sii wanaagsan iska caabbinta biyaha.

8. Waxqabadka dahaadhka korontada: Rabadhka Nitrile waxa uu leeyahay wax-qabad koronto oo liidata, taas oo ay ugu wacan tahay polarity-kiisa.Waxay ka tirsan tahay caag semiconductor ah oo aan loo isticmaalin sida walxaha dahaarka.

9. Iska caabinta gabowga: NBR oo aan lahayn wakiilada gabowga ayaa leh iska caabbinta gabowga oo aad u liidata, halka NBR oo leh wakiilada gabowga ka hortagga gabowga ay ka fiican tahay caabbinta dabiiciga ah.Ka dib gabowga oksaydhiyeyaasha kulaylka ah, xoogga jilicsanaanta caagga dabiiciga ah ayaa si weyn hoos ugu dhacaya, laakiin hoos u dhaca caagga nitrile dhab ahaantii aad ayuu u yar yahay.

Iska caabbinta kulaylka caagga nitrile waxay la mid tahay caabbinta gabowga.Marka L0000H da'da 100 ℃, dhererkeedu wuxuu weli dhaafi karaa 100%.Alaabooyinka caagga ah ee Nitrile waxaa la isticmaali karaa waqti gaaban 130 ° C waxaana lagu isticmaali karaa heerkul sare iyada oo aan lahayn ogsijiin.Sidaa darteed, caag nitrile ah ayaa iska caabbinta kulaylka ka wanaagsan kan dabiiciga ah iyo caagga butadiene ee styrene.Xitaa in ka badan caag chloroprene.Rabadhka Nitrile wuxuu leeyahay cimilo isku mid ah iyo iska caabbinta ozone sida caagga dabiiciga ah, laakiin wax yar ayuu ka hooseeyaa caagga dabiiciga ah.Ku darista chloride polyvinyl caag nitrile ah waxay wanaajin kartaa caabbinta cimilada iyo caabbinta ozone.

10. Iska caabbinta shucaaca:

Rabadhka Nitrile waxa kale oo laga yaabaa in uu waxyeelo gaadho shucaaca nukliyeerka, taas oo keenta korodhka adkaanta iyo hoos u dhaca dhererka.Si kastaba ha ahaatee, marka la barbardhigo caagadaha kale ee synthetic, NBR aad ayuu u saameeyaa shucaaca, iyo NBR oo leh maadada acrylonitrile ee 33% -38% waxay leedahay iska caabin wanaagsan oo shucaac ah.Shucaaca nukliyeerka ka dib, awoodda xajinta ee NBR oo leh maaddo sare oo acrylonitrile ah ayaa lagu kordhin karaa 140%.Tani waa sababta oo ah NBR oo leh maaddo akrylonitrile hoose ah ayaa hoos u dhigi doonta shucaaca hoostiisa, halka NBR oo leh maaddo acrylonitrile sare leh ay mari doonto falcelin iskuxiran oo hoos yimaada shucaaca nukliyeerka.
