Iyini i-NBR-PVC Blend?
Ukuhlanganiswa kwama-polymers kuzuze isithakazelo esikhulu ngenxa yokuthi kungasetshenziswa ukukhiqiza izinto ezintsha ze-polymeric ezinezakhiwo ezithile ezifanele izinhlelo zokusebenza ezithile ezikhethekile.Imixube evela ku-acrylonitrile butadiene rubber (NBR) kanye ne-polyvinyl chloride (PVC) yakhelwe imikhiqizo esebenza ngokuthintana namafutha.Ingxenye ye-PVC ihlinzeka nge-ozone eyengeziwe, ukumelana nelangabi nesimo sezulu, kuyilapho ingxenye ye-NBR inikeza ukuhuzuka okuhle nokumelana namakhemikhali okuhlanganisa uwoyela, izinto zokubasa, nezinye izinhlanganisela ezingezona ezomhlaba.
Ama-elastomer e-NBR/PVC asetshenziswa ezimbonini eziningi nasezimakethe ezihlanganisa ifenisha, isakhiwo nokwakha, izinto zangaphakathi zezimoto, izicathulo, izimpahla zezimboni nezasendlini, kanye nokupakishwa kokudla.Ezinye izinhlelo zokusebenza ezinkulu zihlanganisa amasoli ezicathulo zokuphepha, amarola ephrinta athambile, i-flooring yezimboni, amabhantshi ekhebula anombala kanye nesembozo sepayipi esinemibala.
Umsebenzi we-NBR kunhlanganisela eguquguqukayo ye-PVC
Ukwengezwa kwe-PVC ku-NBR nakho kukhulisa umthamo wokuthwala umbala kumakhompiyutha anemibala, okuholela ekugcinweni okungcono kwemibala egqamile.Le nhlanganisela iphinde ikhombise ukuguquguquka okuphansi kwe-plasticizer ngenxa yokuhlangana okuqinile kwerabha ye-nitrile kumapulasitiki oketshezi ajwayelekile.1
Ngokuya ngokuqukethwe kwe-PVC ne-plasticizer, izingxube ze-NBR-PVC zinikeza ukunwebeka, ukukhuphuka kokumelana nesethi yokucindezelwa, kanye nokuguquguquka okuhle kwezinga lokushisa eliphansi.Imvamisa, ubude ngesikhathi sekhefu buyakhula ngezinga elikhulayo le-NBR kuyilapho amandla e-tensile enyuka ngezinga elikhulayo le-PVC.
I-PVC eguquguqukayo eyenziwe ngepulasitiki ngamapulasitiki avamile ingase ilahlekelwe i-plasticizer ngaphansi kwezimo ezithile futhi ibe lukhuni futhi ibe brittle.Lapho uthintana nophethiloli, i-NBR inciphisa ukukhishwa kwe-plasticizer.I-PVC eguquguqukayo elungiswe nge-NBR ilahlekelwa isisindo esincane lapho ithintana namafutha.Ngakho-ke, ukugcinwa kokuguquguquka nempilo yesevisi ende kuyaqinisekiswa.
I-Nitrile Rubber NBR Izinzuzo
1. Ukuphikelela kwePlasticizer:I-NBR ingakhuphula ukunwebeka kwe-PVC komkhiqizo futhi inciphise inani le-plasticizer esetshenzisiwe;ngesikhathi esifanayo, ngenxa yokuheha ama-plasticizers nokunciphisa isivinini sokufuduka kwama-plasticizers.
2. Ukumelana Okuhle Kakhulukumafutha, uphethiloli, i-hydrolysis namakhemikhali: I-NBR iqukethe inani elikhulu lamaqembu e-CN, angathuthukisa kakhulu ukumelana kwamafutha kanye ne-solvent ye-PVC.
3. Ukuguquguquka Okuhle Kwezinga Lokushisa Eliphansi:Asikho isakhiwo seketanga eliguquguqukayo nesinwebekayo ku-molecule ye-PVC, ngakho-ke ukusebenza kwayo ekushiseni okuphansi kubi.Ngemva kokwengeza i-PNBR elastomer, ukumelana kwayo nezinga lokushisa eliphansi kuyathuthukiswa.
4. Ukumelana Okuhle Kakhulu Kwe-Abrasion:I-NBR ingathuthukisa kakhulu ukumelana nokugqokwa kwe-PVC futhi yandise impilo yesevisi yemikhiqizo.
5. Ukuzinza KweDimensional Okuhle:I-viscosity encibilikayo ye-NBR/PVC izinzile uma kuqhathaniswa nebanga lokushisa elibanzi, eliphumuza izimo zokucubungula zomkhiqizo.
6. Ukuvumelana nezimo okuhlala isikhathi eside:Njenge-elastomer, i-NBR yenza isakhiwo "sesiqhingi-solwandle" lapho sihlanganiswe ne-PVC, okuthuthukisa kakhulu ukuguquguquka kwe-PVC.
7. Ukuthinta Kwerabha:Inhlanganisela ye-PVC ene-NBR ibukeka futhi ithintwa njengerabha.
8. I-Insulation enhle kakhulu:Ukwengeza i-NBR kungathuthukisa ukusebenza kokumelana nomkhiqizo.
Nitrile Rubber NBR PVC Izicelo
Izicathulo, ama-gumboots
Uwoyela gaskets, izimvu zamanzi, sezulu stripping

I-PVC ye-NBR
I-INPVC yinkampani ephethwe kahle ye-PVC eyenza i-NBR PVC.Sibeke ibhentshimakhi yekhwalithi embonini.Izingxube zethu ngokuvamile zaziwa ngokuqina kwazo nokumelana nowoyela.Izinto ezihlanganisiwe ziphinde zibe namandla enqubo ephezulu okuvumela imikhiqizo yethu ukuthi ihlangabezane noma yeqe okucacisiwe.
Ama-NBR e-INPVC avumelana ngokugcwele ne-PVC engakhiqizwa imixube efanayo nezakhiwo eziphakeme.Sinethimba lokuphatha isitoko elisebenza ngempumelelo elikhiqiza izinhlobo ezibanzi kakhulu zemikhiqizo ye-PVC ye-NBR eguquguqukayo ehlanganiswe nekhwalithi nezakhiwo ezinezici ezinhle kakhulu ezifanele uhla lwezinhlelo zokusebenza ngendlela ephumelelayo.Lezi zinhlanganisela ziklanywe futhi zenziwe ngendlela oyifisayo ngemva kokuhlaziya isidingo semakethe kanye nezidingo zamakhasimende.
