Ukuphuculwa kweMveliso ye-HTPB, CTBN kunye ne-DDI (Dimeryl Diisocyanate)

Yintoni i I-HTTPB ?

I-HTTPB kwaziwa njenge i-polybutadiene epheliswe yi-hydroxyl (iNombolo ye-CAS 69102-90-5), yirabha entsha engamanzi (i-resin), I-HTPB inamaqela e-hyroxyl asabelayo. Ingasabela nge-arhente yokwandisa ityathanga, i-arhente yokudibanisa kubushushu begumbi okanye kubushushu obuphezulu ukuvelisa isakhiwo senethiwekhi ye-3D yomxholo wokuphilisa oneempawu ezintle kakhulu zoomatshini.

Iimpawu zokusebenza ze-HTPB zezi: Ukungabandakanywa kwamanzi, Amaqela e-hyroxyl asebenzayo, Ubushushu obuphantsi bokuguquka kweglasi, Umbala ophantsi - ulwelo olucacileyo oluphezulu, Ukumelana ne-hydrolysis,

Ukumelana nobushushu obuphantsi, Ukufuma okuphantsi, Ukumelana nee-asidi zamanzi kunye neziseko, Ukumelana nokuguguleka okunamandla, Ukunamathela okugqwesileyo kwiintlobo ngeentlobo zezixhobo, Iimpawu zokuthintela umbane, Iimpawu ezibalaseleyo zoomatshini zenza ukuba isetyenziswe kakhulu kwi:

- Iingubo

- Izincamathelisi

- Izinto ezibangela uqhushululu

- Izinto zePolyurethane (PU)

- Izibophelelo

- Izinto zokutywina

- Izixhobo zokukhusela umbane

- Iimveliso zerabha

- Izinto zokwakha kwiimoto nakwiinqwelomoya

- Izixhobo zokwakha (ezingangeni manzi, ezilwa nokugqwala, ezithintela ubushushu)

- Ukufaka izimbiza kunye nokufaka ii-capsules

- Ukuguqulwa kwePolymer

- kunye nezinye iindlela ezininzi zokusebenzisa.

Yintoni i I-CTBN ?

I-CTBN ndikwazi nokuba i-copolymer ye-butadiene-acrylonitrile epheliswe yi-carboxyl ( Inombolo ye-CAS 25265-19-4 okanye 68891-46-3), iqela le-carboxyl njengeqela lalo lomsebenzi, lingasetyenziswa ngokubanzi kwiindawo zeenqwelo moya nakwiindawo zoshishino. Ngenxa yeqela elisebenzayo elipheliswe yi-carboxyl, liyakwazi ukusabela nge-epoxy resin ukuphucula ukuqina.

Iimpawu ze-CTBN zezi: Yomeleza ukuqina kunye nokuguquguquka kwee-thermoset resins, Yonyusa ukunamathela kwi-substrates ezinzima ukunamathela kuzo, Yonyusa ukumelana nokuqhekeka, Yonyusa ukuqina (ukumelana nokudinwa), Yonyusa iimpawu zoomatshini ezikumgangatho ophantsi, njl.njl. yenza ukuba isetyenziswe kakhulu kwi:

1. Izinto zokuncamathelisa, ukubopha, ukutywina, ukutshiza, ukugalela kwiimbiza (i-aerospace, iimoto, umbane/i-elektroniki, imboni, ulwandle kunye nezicelo zokwakha..)

2. Iingubo (isicombululo, umgubo, amanzi ahambayo)

3. I-CTBN bubulukhuni be-epoxy resin, kwaye yindlela egqwesileyo yokuguqula ukuguquguquka kwee-thermosetting resin ezifana ne-epoxy, i-phenolic, i-unsaturated polyester kunye nee-photosensitive resins.

Yintoni i HAYI ?

HAYI ndikwazi nokuba Dimeryl Diisocyanate CAS No. 68239-06-5, I-DDI yi-aliphatic diisocyanate eyahlukileyo enokusetyenziselwa ukulungiselela iipolymers ezineekhompawundi eziqulethe i-hydrogen esebenzayo. Yikhompawundi ende ene-36-carbon dimer fatty acid backbone. Ulwakhiwo oluphambili lwekhompawundi lunika i-DDI ukuguquguquka okuphezulu, ukumelana namanzi kunye nobuthi obuphantsi kwezinye ii-aliphatic isocyanates. I-DDI lulwelo olune-viscosity ephantsi olunyibilikayo lula kwii-solvents ezininzi ze-polar okanye ezingezizo ze-polar. Ngenxa yokuba yi-aliphatic isocyanate, ineempawu zokungatyheli. Inezibonelelo ezininzi zobuthi obuphantsi, kulula ukuyisebenzisa, ukunyibilika kwii-solvents ezininzi, ixesha lokuphendula elilawulekayo kunye nobuthathaka obuphantsi bamanzi. Luhlobo oluqhelekileyo lwe-isocyanate ekhethekileyo eluhlaza evuselelekayo, enokusetyenziswa kakhulu ekugqityweni kwelaphu, ii-elastomers, izincamathelisi kunye nezitywina, ii-coating, ii-inki kunye neminye imimandla yomkhosi kunye neyoluntu.

Siphucule imveliso ye-HTPB, CTBN kunye ne-DDI (Dimeryl Diisocyanate) ukuze siphucule ukusebenza kwazo, kwaye senze amaxabiso akhuphisana ngakumbi xa kuthelekiswa ne-Poly BD R45 HTLO, Huntsman 1300X13 (Hypro 1300X13 CTBN).
