Caag ka sameysan waa mid ka mid ah saddexda shey ee ugu waaweyn ee la farsameeyo waxaana si weyn loogu isticmaalaa dhinacyada kala duwan ee warshadaha, difaaca qaranka, gaadiidka iyo nolol maalmeedka.Waxqabadka sare iyo caag synthetic ah oo shaqeynaya waa shay asaasi ah oo horumarsan oo muhiim u ah horumarinta waaga cusub, sidoo kale waa kheyraad istiraatiiji ah oo muhiim u ah dalka.
Qalabka caagga ah ee gaarka ah waxay tixraacaan agabka caagga ah ee ka duwan kan caagga guud oo leh sifooyin gaar ah sida iska caabbinta heerkul sare iyo mid hooseeya, caabbinta gabowga, caabbinta caabbinta, caabbinta kiimikaad, badiyaa hydrogenated nitrile rubber (HNBR), thermoplastic vulcanizate (TPV) , Caag Silikoon ah, caag fluorine, caag fluorosilicone, caag acrylate, iwm Sababo la xiriira sifooyinka gaarka ah, qalabka caag gaar ah ayaa noqday qalabka muhiimka ah ee lagama maarmaanka u ah horumarinta xeeladaha waaweyn ee qaranka iyo beeraha soo baxaya sida hawada hawada, difaaca qaranka iyo warshadaha military. macluumaadka elektarooniga ah, tamarta, deegaanka, iyo badda.
1. caag nitrile hydrogenated (HNBR)
Rabadhka nitrile Hydrogenated waa shay caag aad u buuxa oo la helay iyada oo si door ah hydrogenating unugyada butadiene ee silsiladda caagga nitrile ujeedada hagaajinta caabbinta kulaylka iyo caabbinta gabowga ee caagga nitrile butadiene (NBR)., muuqaalkeeda ugu muhiimsan waa in loo isticmaali karo waqti dheer 150 ℃, waxayna wali sii wadi kartaa guryaha sare ee jirka iyo farsamada heerkulka sare, kaas oo si fiican u buuxin kara shuruudaha gaarka ah ee caabbinta heerkulka sare iyo caabbinta kiimikada ee alaabta baabuurta. , hawada sare, goobta saliida iyo goobo kale.Shuruudaha, oo aad iyo aad u badan oo si ballaaran loo isticmaalo, sida shaabadda saliidda baabuurta, qaybaha nidaamka shidaalka, suumanka gudbinta baabuurta, dalool sanduuqa haynta iyo pistons ee dhoobada, daabacaadda iyo rollers caag dun ah, shaabadihii hawada hawada, alaabta nuugista naxdinta, iwm.
2. Thermoplastic Vulcanizate (TPV)
vulcanizates Thermoplastic, oo loo soo gaabiyo TPVs, waa nooc gaar ah oo ah elastomers thermoplastic oo ay soo saarto "vulcanization dynamic" oo ah isku-dhafka heerkulbeegyada iyo alastomers, ie xulashada wejiga elastomerka marka la dhalaalayo isku dhafka heerkulbeegga ee iskutallaabta galmada.vulcanization isku mar ah ee wejiga cinjirka ee joogitaanka wakiilka crosslinking (laga yaabaa peroxides, diamines, sulfur accelerators, iwm) inta lagu guda jiro qaso kulaylka natiijada in a vulcanizate firfircoon matrix joogto ah oo ka kooban caag crosslinked kala firdhiyey Qaybaha wajiga, firfircoon. vulcanization waxay keentaa korodhka viscosity caag ah, kaas oo kor u rogaa wejiga oo bixiya qaab-dhismeedka multiphase ee TPV.TPV waxay leedahay labadaba waxqabadka la mid ah caagga heerkulbeegga iyo xawaaraha farsamaynta ee heerkulbeegyada, kuwaas oo inta badan lagu muujiyey waxqabadka sare / saamiga qiimaha, naqshad dabacsan, miisaan fudud, kala duwanaansho heerkul hawleed oo ballaadhan, habayn fudud, tayada badeecada iyo xasilloonida cabbirka iyo dib loo warshadayn karo, si ballaaran loo isticmaalo qaybaha baabuurta, dhismaha korontada, shaabadihii iyo beeraha kale.
3. caag silikoon ah
Caag silikoon ah waa nooc gaar ah oo caag synthetic ah kaas oo ka samaysan polysiloxane toosan oo lagu qasay buuxinyaal xoojinaya, buuxinta shaqaynaysa iyo waxyaabaha lagu daro, oo noqda elastomer shabakad u eg ka dib vulcanization ee xaaladaha kulaylinta iyo cadaadiska.Waxay leedahay iska caabin heerkul sarreeya oo hooseeya, iska caabin cimilo, caabbinta ozone, caabbinta arc, dahaarka korantada, caabbinta qoyaanka, xawliga hawada sare iyo inertia jireed.Waxay leedahay codsiyo badan oo kala duwan oo ku saabsan warshadaha casriga ah, elektiroonigga iyo korantada, baabuurta, dhismaha, caafimaadka, daryeelka shakhsi ahaaneed iyo qaybaha kale, waxayna noqotay wax aan laga maarmi karin oo horumarsan oo wax qabad sare leh oo ku saabsan hawada, difaaca iyo warshadaha milatariga, wax soo saarka caqliga leh iyo qaybaha kale. .
4. caag fluorine
Caag Fluorine waxaa loola jeedaa walxo caag ka kooban fluorine oo ay ku jiraan atamka fluorine ee atamka kaarboon ee silsiladda ugu weyn ama silsiladaha dhinaca.Sifooyinkeeda gaarka ah waxaa lagu go'aamiyaa sifooyinka qaab dhismeedka atamka fluorine.Caag Fluorine ah ayaa lagu isticmaali karaa 250°C muddo dheer, heerkulka adeega ugu badnaan wuxuu gaari karaa 300°C, halka xadka adeega ee caag-dhaqameedka EPDM iyo butyl uu yahay 150°C oo kaliya.Marka lagu daro iska caabbinta heerkulka sare, fluororubber waxay leedahay iska caabin saliid oo heer sare ah, caabbinta kiimikada, caabbinta aashitada iyo alkali, iyo waxqabadkeeda dhamaystiran ayaa ah kan ugu fiican dhammaan qalabka elastomer-ka caagga ah.Waxaa inta badan loo isticmaalaa iska caabinta saliida ee gantaalada, gantaalada, diyaaradaha, maraakiibta, baabuurta iyo baabuurta kale.Goobaha ujeedooyinka gaarka ah leh sida dhuumaha shaabadeynta iyo saliida u adkeysaneysa ayaa ah waxyaabaha lagama maarmaanka u ah dhaqaalaha qaranka iyo difaaca qaranka iyo warshadaha militariga.
5. caag acrylate ah (ACM)
Acrylate rubber (ACM) waa elastomer lagu helay kobolymerization of acrylate sida monomer-ka ugu weyn.Silsiladdeeda ugu weyn waa silsilad kaarboon oo saturated ah, kooxaheeduna waa kooxo ester polar ah.Sababtoo ah qaab-dhismeedka gaarka ah, waxay leedahay sifooyin badan oo aad u fiican, sida caabbinta kulaylka, caabbinta gabowga, caabbinta saliidda, caabbinta ozone, caabbinta UV, iwm. , caabbinta gabowga iyo caabbinta saliidda ayaa aad u fiican.in caag nitrile ah.ACM waxaa si weyn loogu isticmaalaa jawi kuleyl sare leh oo kala duwan iyo deegaan u adkaysta saliidda, waxayna noqotay wax daboolaya oo ay horumariyeen warshadaha baabuurta sanadihii la soo dhaafay.
