I-CTBN iyi-polymer eguquguqukayo kakhulu ehlanganisa izakhiwo ze-butadiene ne-acrylonitrile. Isetshenziswa kabanzi njengesithako esiqinile kuma-resin epoxy, ama-thermoplastics nezinye izinto ukuze kuthuthukiswe ukuqina kwawo, ukumelana nomthelela kanye nokuguquguquka. Le elastomer itholakala ngezinhlobo ezahlukene zezinhlobo ezinesisindo sama-molecule ahlukene kanye nokuqukethwe kwe-carboxyl ukuze kuhlinzekwe ngezixazululo ezenziwe ngokwezifiso ngokusekelwe ezicini ezidingekayo.
Enye yezimpawu ezibalulekile ze I-CTBNiyisiguquguquki sayo esihle kakhulu sokushisa okuphansi. Ihlala iguquguquka futhi inwebeka ngisho nasezindaweni ezibandayo kakhulu, okwenza ibe yindawo ekahle kakhulu ezindaweni ezibandayo noma ezindaweni lapho kulindeleke khona ukuthi ibhekane namazinga okushisa aphansi. Lesi sici siqinisekisa ukuthi izinto eziqukethe i-CTBN zigcina ubuqotho bazo nokusebenza kwazo ngisho nangaphansi kwezimo ezinzima.
Ngaphezu kwalokho, i-CTBN inokunamathela okuhle kakhulu ezintweni ezahlukahlukene, okuhlanganisa izinsimbi, ipulasitiki kanye nezinto ezihlanganisiwe. Le mpahla yokunamathela iyenza ibe yisithako esibalulekile ekumbozeni, ezintweni zokunamathela kanye nasezivaleni, okuthuthukisa amandla azo okubopha kanye nokuphila kwenkonzo. Ukuhambisana kwe-CTBN nezinto ezahlukahlukene kuthuthukisa ukusebenza kwayo ezimbonini ezahlukene.
Ngaphezu kwalokho, i-CTBN yaziwa ngokumelana kwayo okuhle kakhulu nokushayisana. Imunca futhi isabalalise amandla okushayisana, ivimbele izinto ukuthi zingaqhekeki futhi ziphuke. Lesi sici sibaluleke kakhulu ekusetshenzisweni lapho ukumelana nokushayisana nokushayisana kubaluleke kakhulu, njengezindiza, izimoto, kanye nemishini yezemidlalo. Ngokufaka i-CTBN kulezi zinto, abakhiqizi bangaqinisekisa ukuthi imikhiqizo yabo ingakwazi ukumelana nezimo zesevisi ezinzima.
Enye indawo lapho I-CTBNI-excels ihlinzeka ngokuqina kanye nokunwebeka kuma-polymer aqinile. Ngokuhlanganisa i-CTBN nama-polymer e-thermoset njenge-epoxy resins, izinhlanganisela eziphumayo zibonisa ukuqina okuthuthukisiwe kanye nokumelana nokuqhekeka. Lesi sici siwusizo kakhulu ekukhiqizeni izingxenye ezifana nemishini esindayo, izakhi zesakhiwo kanye nezivikeli zikagesi.
Inhlanganisela eyingqayizivele yezakhiwo ezinikezwa yi-CTBN iyenza ibe yinto ewusizo emikhakheni eyahlukahlukene. Onjiniyela bezindiza basebenzisa i-CTBN kuma-seal elastomeric, ama-gasket kanye nezingxenye ezidambisa ukudlidliza. Embonini yezimoto, i-CTBN isetshenziswa kuma-impact absorbers, ama-underbody coating kanye nezingxenye zesistimu kaphethiloli.I-CTBNisetshenziswa kabanzi ekukhiqizweni kwezimpahla zemidlalo ezisebenza kahle kakhulu, okuhlanganisa amabhola egalofu, izinduku zehoki kanye nezicathulo zemidlalo.
Ngamafuphi, i-CTBN (i-carboxyl-terminated butadiene acrylonitrile) iyi-elastomer eguquguqukayo ethuthukisa izakhiwo zezinto ezibonakalayo. Ngokuguquguquka kwayo okuhle kakhulu kokushisa okuphansi, ukunamathela, ukumelana nokuqina komthelela, i-CTBN isetshenziswa kabanzi ezimbonini ezifana nezindiza, izimoto kanye nezemidlalo. Njengoba ubuchwepheshe buthuthuka kanye nesidingo sezinto zokusebenza okuphezulu sanda, i-CTBN cishe izoqhubeka nokudlala indima ebalulekile ekuthuthukiseni ukuthembeka nokuqina kwemikhiqizo eyahlukahlukene.
Singabahlinzeki abaphezulu be-CTBN eShayina, sinikeza izinhlobo ezahlukene ze-CTBN nezinye izinto ezihlobene ezifana I-HTTPB, I-ATBN, I-ATTB, njll.. okwamanje singakwazi ukucwaninga nokuthuthukisa i-CTN entsha ngokwesidingo esikhethekile samakhasimende ethu. Nanka amanye amazinga ethu e-CTN, ukuze uthole okwengeziwe sicela uxhumane nathi nge info@theoremchem.com
