Iimpawu ze-CTBN kunye neendawo zokusetyenziswa
I-CTBN I-Epoxy Esetyenziselwa Iingubo Eziphezulu Nezincamathelisi
I-CTBN (i-Carboxyl-Terminated Butadiene Nitrile) yipolymer eguquguqukayo esetyenziswa kakhulu ekuqulunqweni kweengubo ze-epoxy kunye nee-adhesives ezisebenza kakuhle.
Le nto ikhethekileyo inika uluhlu lweempawu eziluncedo, nto leyo eyenza ukuba ibe lukhetho olufanelekileyo kwizicelo ezifuna ukuqina okugqwesileyo, ukuguquguquka, kunye nokumelana neekhemikhali.
Xa zidityaniswe nee-epoxy resins, i-CTBN iphucula ukusebenza ngokubanzi kweefomyula ezivelayo, nto leyo eyenza zifaneleke kwiintlobo ngeentlobo zemizi-mveliso ezifuna kakhulu.
izicelo zorhwebo.
Enye yezona nzuzo ziphambili zokusebenzisa I-CTBN (irabha ye-nitrile butadiene epheliswe yi-carboxy) i-epoxy kukukwazi kwayo ukuphucula ukuqina kunye nokumelana nempembelelo kweengubo kunye
izincamathelisi. Ukufakwa kwe-CTBN kwiifomyula ze-epoxy kunokuphucula kakhulu amandla azo okumelana noxinzelelo loomatshini, oku kuzenze zilungele ukusetyenziswa kwiindawo apho ukukrala kunye nempembelelo zixhaphakileyo. Oku kwenza ukuba i-epoxy ye-CTBN ukhetho oluhle kakhulu kwiingubo zokukhusela ezisetyenziswa kumashishini afana neenqwelo-moya, iimoto, kunye nezolwandle,
apho ukuqina nokuqina kubalulekile.
Ngaphezu koko, Irabha ye-CTBN inika ukuguquguquka okugqwesileyo, okubaluleke kakhulu kwizicelo ezibandakanya ukuhamba kwe-substrate okanye ukujikeleza kobushushu.
Iingubo ze-epoxy eziguqulwe yi-CTBN kunye nee-adhesives zivumela ukuba zigcine ukuthembeka kwazo kunye nokunamathela kwazo nokuba ziphantsi kwamaqondo obushushu ahlukeneyo kunye noxinzelelo loomatshini.
Oku kuzenza zilungele ukusetyenziswa kwiindawo apho izinto zokugquma okanye izincamathelisi zemveli zinokungasebenzi kakuhle, njengakwizakhiwo, kwiziseko zophuhliso, nakwizinto ze-elektroniki.
Ukongeza kwiipropati zayo zoomatshini, i-polymer ye-CTBN ikwabonelela ngokumelana okubalaseleyo kweekhemikhali. Ubukho bamaqela e-nitrile kwi-polymer ye-CTBN bunika isiphumo esihle kakhulu
ukumelana neekhemikhali ezahlukeneyo, kuquka izinyibilikisi, amafutha, kunye nee-asidi. Oku kwenza ukuba i-epoxy coating kunye ne-glues ze-CTBN zilungele ukusetyenziswa kwiindawo apho kuchaphazeleka khona
Iikhemikhali ezinobungozi ziyinto exhalabisayo, njengezityalo zokucubungula iikhemikhali, izibonelelo zeoyile negesi, kunye nemisebenzi yokuvelisa imizi-mveliso.
Ngaphezu koko, iifomyula ze-CTBN zibonisa ukunamathela okuhle kwiindawo ezahlukeneyo, kubandakanya iintsimbi, iiplastiki, kunye nee-composites. Oku kuvumela ukudalwa kweebhondi eziqinileyo nezihlala ixesha elide phakathi kwezinto ezahlukeneyo, okwenza Ikhemikhali ye-CTBN izincamathelisi zilukhetho oluhle kakhulu kwizicelo zokubopha izakhiwo kumashishini afana nokwakha, ezothutho,
kunye nezixhobo ze-elektroniki.
Ukuguquguquka kwe-CTBN kufikelela ekulungelelanisweni kwayo neendidi ezahlukeneyo zezinto zokunyanga kunye nezongezo, okuvumela iifomyula ukuba zilungelelanise iimpawu zepeyinti yokugqibela kunye nezincamathelisi.
ukuhlangabezana neemfuno ezithile zokusebenza. Olu kuguquguquka lwenza kube lula ukuphuhliswa kwezisombululo ezenzelwe wena ngokweemfuno ezahlukeneyo, ukusuka kwiingubo ezinganyangekiyo ngumhlwa
kwizincamathelisi ezimelana neempembelelo.
Ukuqukumbela, i-CTBN inika indibaniselwano enomtsalane yokuqina, ukuguquguquka, ukumelana neekhemikhali, kunye nokunamathela, nto leyo eyenza ukuba ibe lukhetho oluhle kakhulu kwiingubo ezisebenza kakuhle.
kunye nezincamathelisi. Amandla ayo okuphucula iimpawu zoomatshini kunye neekhemikhali ze-epoxy formulations enza ukuba ibe sisixhobo esibalulekileyo sokujongana neemfuno ezifunekayo ze
amashishini ahlukeneyo. Njengoko uphando nophuhliso kwisayensi yepolymer luqhubeka luhambela phambili, kulindeleke ukuba i-epoxy ye-CTBN idlale indima ebaluleke ngakumbi kuphuhliso
izisombululo zokuncamathelisa ezintsha nezizinzileyo.
Sinikezela I-CTBN ngeenguqulelo ezahlukeneyo ezinje, ukusebenza kufana nokwe-HUNSTMAN 1300X13.
