Kuongororwa kweHTPB neCTPB
Zvinhu Zvinokosha Zvaunofanira Kuziva
- HTTPB yakanakira maapplication inoda simba uye kugara kwenguva refu, zvakaita sekushandiswa kwemuchadenga nemauto. Inopa simba rakanaka rekudzivirira makemikari uye kuchinjika mumamiriro ezvinhu akaoma.
- CTPB inobudirira zvikuru kana tembiricha yakaderera Kuchinjika uye kusimba, zvichiita kuti ive yakakodzera ma epoxies akaomarara uye ma flexible composites. Inowedzera mashandiro ezvinhu mukuchengetedza simba uye mashandisirwo epamusoro.
- Pakusarudza pakati peHTPB neCTPB, funga nezvezvinodiwa neprojekiti yako. HTPB iri nani kune mashandisirwo anoshanda zvakanyanya uye asingashandise makemikari, nepo CTPB iri sarudzo inodhura zvishoma yezvinhu zvinochinjika uye zvakasimba.
Maumbirwo emakemikari uye kuumbwa kweHTPB (Hydroxyl-terminated polybutadiene) CAS 69102-90-5; Carboxyl-terminated polybutadiene (CTPB) CAS 586976-24-1
Maumbirwo eHTTPB uye Zvinhu Zvikuru
Unowana izvozvo HTPB ine musana unochinjika nemapoka ehydroxyl kumagumo ese. Mapoka aya ehydroxyl anoita sema handles anobatsira HTPB kuita zvimwe zvinhu, kunyanya isocyanates. Kuita uku kunogadzira urethane bonds dzakasimba. HTPB inoshanda se polyol muzvigadzirwa zve polyurethane. Maumbirwo ayo anogona kuchinja zvichienderana nehuwandu hwe cis, trans, uye vinyl units mucheni. Kana ukawedzera cis units, unowana elasticity yakawanda. Ma trans units akawanda anokupa simba rakawedzerwa. Masayendisiti anoshandisa maturusi akaita seFTIR neNMR kudzidza HTPB uye kuona kuti shanduko idzi dzinokanganisa sei zvinhu zvakaita se viscosity uye girazi transition temperature.
Cherechedza: Huremu hwemamorekuru uye chimiro cheHTPB zvinogona kugadziriswa kuti zvienderane nemashandisirwo akasiyana, akadai semaglue kana rocket propellants.
Maumbirwo eCTPB uye Zvinhu Zvikuru
CTPB ine mapoka emakabhokisairi kumativi ese echeni yayo. Mapoka ecarboxyl aya anoita kuti CTPB ive yakanaka kwazvo pakugadzira ma crosslinks ane polar curing agents. Unoona kuti CTPB irabha yemvura ine simba rekudzivirira kutonhora uye flexible. Mapoka ecarboxyl anogona kuita ne epoxy resins, iyo inobatsira kusimbisa chigadzirwa chekupedzisira. CTPB inewo cis-1,4 content yakakwira, iyo inoita kuti ive flexible yakanaka pakupisa kwakaderera. Kana ichienzaniswa nezvinhu zvakafanana, CTPB ine viscosity yakaderera uye processability iri nani.
- Mapoka emakabhokisi ari muCTPB anobatsira kuti ibatane nemamwe makemikari.
- Maumbirwo eCTPB anoita kuti igare ichichinjika kunyangwe munzvimbo dzinotonhora.
- Unogona kushandisa CTPB kuti uwedzere kusimba kwema epoxy resins.
