Ukuthuthukiswa Kokukhiqiza kwe-HTPB, CTBN kanye ne-DDI (Dimeryl Diisocyanate)
Kuyini I-HTTPB ?
I-HTTPB obeye aziwe njengo i-polybutadiene eqediwe yi-hydroxyl (Inombolo ye-CAS 69102-90-5), iyirabha entsha ewuketshezi (i-resin), Ama-HTPB anamaqembu e-hyroxyl asabelayo. Ingasabela nge-ejenti yokwandisa uchungechunge, i-ejenti yokuxhumanisa ekushiseni kwegumbi noma ekushiseni okuphezulu ukuze ikhiqize isakhiwo senethiwekhi ye-3D sokuqukethwe kokupholisa okunezakhiwo ezinhle kakhulu zemishini.
Izakhiwo zokusebenza ze-HTPB njenge: Ukungathandi amanzi, Amaqembu e-hyroxyl asebenzayo, Izinga lokushisa eliphansi lokuguquka kwengilazi, Umbala ophansi - uketshezi oluqinile olucacile, Ukumelana ne-hydrolysis,
Ukumelana nokushisa okuphansi, Ukuvuleka komswakama okuphansi, Ukumelana nama-asidi amanzi kanye nezisekelo, Ukumelana nokuguguleka okunamandla, Ukunamathela okuhle kakhulu ezinhlotsheni ezahlukene ze-substrate, Izakhiwo zokuvimbela ugesi, Izakhiwo ezinhle kakhulu zemishini zenza ukuthi isetshenziswe kabanzi ku:
- Ukugqoka
- Izinamathiseli
- Ama-propellant
- Izinto ze-Polyurethane (PU)
- Izihlanganisi
- Izinto zokuvala
- Izinto zokuvikela ugesi
- Imikhiqizo yerabha
- Izinto zokwakha ezimotweni nasezindizeni
- Izinto zokwakha (ezingangeni manzi, ezilwa nokugqwala, ezivikela ukushisa)
- Ukufaka izimbiza kanye nokufaka i-capsulation
- Ukuguqulwa kwePolymer
- nezinye izinhlobo eziningi zokusetshenziswa.
Kuyini I-CTBN ?
I-CTBN futhi wazi njengo i-copolymer ye-butadiene-acrylonitrile eqediwe yi-carboxyl ( Inombolo ye-CAS 25265-19-4 noma 68891-46-3), iqembu le-carboxyl njengeqembu lalo lomsebenzi, lingasetshenziswa ngokuvamile ezindizeni nasezindaweni zezimboni zomphakathi. Ngenxa yeqembu elisebenzayo eliqediwe yi-carboxyl, likwazi ukusabela nge-epoxy resin ukuthuthukisa ukuqina.
Izici ze-CTBN njenge: Kuthuthukisa ukuqina nokuguquguquka kwama-resin e-thermoset, Kuthuthukisa ukunamathela kuma-substrate okunzima ukuwabopha, Kwandisa ukumelana nokuqhekeka, Kuthuthukisa ukuqina (ukumelana nokukhathala), Kwandisa izakhiwo zemishini ezisezingeni eliphansi lokushisa, njll. kwenza ukuthi isetshenziswe kabanzi ku:
1. Izinto zokunamathisela, ukubopha, ukuvala, ukufutha, ukufaka izimbiza (izindiza, izimoto, ugesi/izinto zikagesi, izimboni, ezolwandle kanye nezokwakha..)
2. Izimbozo (isisombululo, impuphu, amanzi)
3. I-CTBN iwukuqina kwe-epoxy resin, futhi iyisiguquli esihle kakhulu sokuguquguquka kwama-resin okusetha ukushisa njenge-epoxy, i-phenolic, i-polyester engagcwali kanye nama-resin azwela ukukhanya.
Kuyini CHA ?
CHA futhi wazi njengo I-Dimeryl Diisocyanate CAS No. 68239-06-5, i-DDI iyi-aliphatic diisocyanate ehlukile engasetshenziswa ukulungiselela ama-polymer anamakhemikhali aqukethe i-hydrogen esebenzayo. Iyinhlanganisela yeketanga elide enomgogodla we-36-carbon dimer fatty acid. Isakhiwo seketanga eliyinhloko sinikeza i-DDI ukuguquguquka okuphezulu, ukumelana namanzi kanye nobuthi obuphansi kwamanye ama-aliphatic isocyanates. I-DDI iwuketshezi olune-viscosity ephansi oluncibilika kalula kuma-solvent amaningi e-polar noma angewona ama-polar. Ngenxa yokuthi iyi-aliphatic isocyanate, inezici zokungaphuzi. Inezinzuzo eziningi zobuthi obuphansi, kulula ukuyisebenzisa, incibilika kuma-solvent amaningi, isikhathi sokusabela esilawulekayo kanye nokuzwela kwamanzi okuphansi. Iyinhlobo ejwayelekile ye-isocyanate ekhethekile eluhlaza evuselelekayo, engasetshenziswa kabanzi ekuqedeni indwangu, ama-elastomers, ama-adhesive nama-sealant, ama-coating, ama-ink kanye neminye imikhakha yezempi neyezomphakathi.
Sithuthukise ukukhiqizwa kwe-HTPB, CTBN kanye ne-DDI (Dimeryl Diisocyanate) ukuze sithuthukise ukusebenza kwazo, futhi senze amanani ancintisana kakhulu uma kuqhathaniswa ne-Poly BD R45 HTLO, Huntsman 1300X13 (Hypro 1300X13 CTBN).
