Yintoni iNBR-PVC Blend?
Ukudibanisa iipolymers kufumene umdla omkhulu ngenxa yokuba ingasetyenziselwa ukuvelisa izinto ezintsha zepolymeric ezineempawu ezithile ezifanelekileyo kwizicelo ezikhethekileyo.Iingxube ezivela kwirubha ye-acrylonitrile butadiene (NBR) kunye ne-polyvinyl chloride (PVC) yenzelwe iimveliso ezisebenza ngokudibana namafutha.Inxalenye ye-PVC ibonelela nge-ozone eyandisiweyo, idangatye kunye nokuchasana kwemozulu, ngelixa isahlulo se-NBR sibonelela nge-abrasion elungileyo kunye nokumelana neekhemikhali kubandakanya i-oyile, i-fuel, kunye nezinye iikhompawundi ze-nonpolar.
I-elastomers ze-NBR/PVC zisetyenziswa kumashishini amaninzi nakwiimarike ezibandakanya ifanitshala, ulwakhiwo nolwakhiwo, izinto zangaphakathi zeemoto, izihlangu, iimpahla zemizi-mveliso nezasekhaya, kunye nokupakishwa kokutya.Ezinye izicelo eziphambili ziquka iisoli zezihlangu zokhuseleko, iirola zokuprinta ezithambileyo, umgangatho woshishino, iibhatyi zekheyibhile ezinemibala kunye nezigqubuthelo zemibhobho enemibala.
Umsebenzi we-NBR kwikhompawundi eguquguqukayo yePVC
Ukongezwa kwe-PVC kwi-NBR nako kwandisa umthamo wokuthwala i-pigment kwiikhompawundi ezinemibala, okubangela ukugcinwa okungcono kwemibala eqaqambileyo.Lo mdibaniso ubonisa ukuguquguquka okuphantsi kweplastiki ngenxa yokuqina kwerabha ye-nitrile kwiiplastiki zolwelo eziqhelekileyo.1
Ngokuxhomekeke kwi-PVC kunye nomxholo we-plasticizer, i-NBR-PVC idibanisa inika ukuqina, ukunyuka kwe-compression set resistance, kunye nokuguquguquka okuhle kobushushu obuphantsi.Ngokwesiqhelo, ubude bekhefu buyanda ngokwanda kwenqanaba le-NBR ngelixa amandla okuqina anyuka ngokwanda kwenqanaba lePVC.
I-PVC eguquguqukayo eyenziwe ngeplastiki kunye ne-plasticizers eqhelekileyo inokulahlekelwa i-plasticizer phantsi kweemeko ezithile kwaye ibe lukhuni kwaye ibe brittle.Ukudibana namafutha, i-NBR inciphisa ukutsalwa kweplastiki.I-PVC eguquguqukayo eguqulwayo kunye ne-NBR ilahlekelwa ubunzima obuncinci xa idibene neoli.Ke ngoko, ukugcinwa kokuguquguquka kunye nobomi benkonzo obude buqinisekisiwe.
I-Nitrile Rubber ye-NBR eluncedo
1. Ukuzingisa kwePlastiki:I-NBR inokunyusa i-PVC elasticity yemveliso kunye nokunciphisa inani leplastiki esetyenzisiweyo;ngelo xesha, ngenxa yokutsala iiplasticizers kunye nokunciphisa isantya sokufuduka kweeplasticizers.
2. Ukuchasa okugqwesileyokwioli, i-fuel, i-hydrolysis kunye neekhemikhali: I-NBR iqulethe inani elikhulu lamaqela e-CN, anokuphucula kakhulu i-oyile kunye nokuchasana kwe-solvent ye-PVC.
3. Ukuguquguquka okuhle kobushushu obuphantsi:Ayikho i-flexible kunye ne-elastic chain structure kwi-molecule ye-PVC, ngoko ke ukusebenza kwayo kwiqondo lokushisa eliphantsi kubi.Emva kokongeza i-PNBR elastomer, ukuxhathisa kwayo okuphantsi kobushushu kuyaphuculwa.
4. Ukuxhathisa okugqwesileyo kwe-Abrasion:I-NBR inokuphucula kakhulu ukuxhatshazwa kwePVC kunye nokwandisa ubomi benkonzo yeemveliso.
5. Uzinzo oluLungileyo lweDimensional:I-viscosity enyibilikayo ye-NBR/PVC izinzile kuluhlu olubanzi lweqondo lokushisa, elikhulula iimeko zokucubungula imveliso.
6. Ukuguquguquka okuhlala ixesha elide:Njenge-elastomer, i-NBR yenza i-"sea-island" isakhiwo xa ihlanganiswe ne-PVC, ephucula kakhulu ukuguquguquka kwe-PVC.
7. Ukuchukumisa irabha:Ikhompawundi yePVC ene-NBR ijongeka kwaye ichukunyiswe njengeRubha.
8. I-Insulation egqwesileyo:Ukongeza i-NBR kunokuphucula ukusebenza kwemveliso.

I-PVC ye-NBR
I-INPVC yinkampani yokuvelisa iPVC elawulwa kakuhle eyenza i-NBR PVC.Simisele ibhenchmark yomgangatho kushishino.Iingxube zethu ziyaziwa ngokubanzi ngokuhlala kwazo kunye nokuchasana neoli.Iimathiriyeli ezidityanisiweyo zikwanazo inkqubo yobuchule obuphezulu obuvumela iimveliso zethu ukuba zihlangane okanye zigqithise imilinganiselo.
Ii-NBR ze-INPVC zilungelelaniswa ngokupheleleyo kunye ne-PVC ezinokuveliswa imixube elinganayo eneempawu eziphezulu.Sineqela lolawulo lwempahla esebenzayo elivelisa olona didi lubanzi lweemveliso ze-PVC ze-NBR eziguquguqukayo ezidityaniswe nomgangatho kunye neepropati ezineempawu ezibalaseleyo ezifanelekileyo kuluhlu lwezicelo ngendlela enempumelelo.Ezi ndibaniselwano ziyilwe kwaye zenziwe ngokwezifiso emva kokuhlalutya imfuneko yemarike kunye neemfuno zabaxhasi.
