Kugadziriswa kweHTPB, CTBN uye DDI (Dimeryl Diisocyanate)

Chii HTTPB ?

HTTPB inozivikanwawo se polybutadiene yakagumiswa nehydroxyl (CAS Nhamba 69102-90-5), irabha itsva yemvura (resin), HTPB ine mapoka ehyroxyl anopindura. Inogona kuita nechinhu chinobatanidza cheni, chinhu chinobatanidza tembiricha yemumba kana tembiricha yepamusoro kuti igadzire chimiro che3D network chekugadzirisa zvinhu zvine hunhu hwakanaka hwemakanika.

Hunhu hwekushanda kweHTPB ndehwekuti: Hydrophobicity, Reactive hyroxyl groups, Low glass transition temperature, Low color - high clearness viscous liquid, Resistance to hydrolysis,

Kudzivirira tembiricha yakaderera, Kupinda kwemvura shoma, Kuramba maasidhi emvura uye mabhesi, Kuramba kupfeka kwakasimba, Kunamatira kwakanaka kune akasiyana-siyana ma substrates, Hunhu hwemagetsi hunochengetedza kupisa, Hunhu hwakanaka hwemakanika hunoita kuti ishandiswe zvakanyanya mu:

- Kuputira

- Zvinonamira

- Zvinofambisa

- Zvinhu zvePolyurethane (PU)

- Zvisungo

- Zvisimbiso

- Zvinhu zvemagetsi zvinodzivirira kupisa

- Zvigadzirwa zverabha

- Zvivako zvemota nendege

- Zvinhu zvekuvaka (zvinodzivirira mvura, zvinodzivirira ngura, zvinodzivirira kupisa)

- Kuisa muhari uye kufukidza

- Kugadziriswa kwePolymer

- nedzimwe nzira dzakawanda dzekushandisa.

Chii CTBN ?

CTBN vanozivawo se copolymer yebutadiene-acrylonitrile yakagumiswa nekabhoksili ( CAS Nhamba 25265-19-4 kana 68891-46-3), boka re carboxyl seboka raro rinoshanda, rinogona kushandiswa zvakanyanya munzvimbo dzendege uye dzemaindasitiri. Nekuda kweboka rinoshanda rakagumiswa ne carboxyl, rinogona kuita ne epoxy resin kuwedzera kusimba kwayo.

Zvinhu zviri muCBTN ndeizvi: Zvinowedzera kusimba uye kuchinjika kwema thermoset resins, Zvinovandudza kunamira kune substrates dzakaoma kubatana nadzo, Zvinowedzera kuramba kukanganiswa uye kutsemuka, Zvinovandudza kugara kwenguva refu (kuramba kuneta), Zvinowedzera hunhu hwemakanika husina kupisa zvakanyanya, nezvimwewo zvinoita kuti ishandiswe zvakanyanya mu:

1. Zvinonamira, zvinosunga, zvinovhara, zvinopfapfaidza, zvinoisa muhari (nzvimbo yendege, mota, zvemagetsi/zvemagetsi, zvemaindasitiri, zvemugungwa uye zvekuvaka..)

2. Kuputira (mushonga, hupfu, mvura)

3. CTBN isimba re epoxy resin, uye inogadzirisa kuchinjika kwakanaka kwema resin e thermosetting akadai se epoxy, phenolic, unsaturated polyester uye ma resin anonzwa chiedza.

Chii AIHWA ?

AIHWA vanozivawo se Dimeryl Diisocyanate CAS Nhamba 68239-06-5, DDI imhando yakasiyana ye aliphatic diisocyanate inogona kushandiswa kugadzira ma polymer ane makemikari ane active hydrogen. Imusanganiswa wecheni refu une musana we 36-carbon dimer fatty acid. Chimiro chikuru checheni chinopa DDI kuchinjika kwakanyanya, kuramba mvura uye kuchetura kushoma kune mamwe aliphatic isocyanates. DDI imvura ine viscosity yakaderera inonyungudika nyore nyore mu solvents zhinji dze polar kana dzisiri polar. Nekuti i aliphatic isocyanate, ine hunhu hwekuti haisi yero. Ine mabhenefiti akawanda echepfu shoma, iri nyore kushandisa, inonyungudika mu solvents dzakawanda, nguva yekudzora inodzorwa uye kushoma kwemvura. Imhando yakajairika ye green biorenewable special isocyanate, iyo inogona kushandiswa zvakanyanya mukupedzisa machira, elastomers, adhesives uye sealants, coatings, inks nedzimwe nzvimbo dzemauto nedzehurumende.

Tagadzirisa kugadzirwa kweHTPB, CTBN neDDI (Dimeryl Diisocyanate) kuti tivandudze mashandiro avo, uye tiwedzere kukwikwidzana mumitengo zvichienzaniswa nePoly BD R45 HTLO, Huntsman 1300X13 (Hypro 1300X13 CTBN).
