I-Dioctyl Sebacate

I-Dioctyl Sebacate (DOS) ephezulu iyipulasitiki ekwazi ukumelana nokubanda enegama lamakhemikhali elithi bis(2-ethylhexyl) sebacate kanye nenombolo ye-CAS 122-62-3 . Isebenza njenge-plasticizer ye-diester enhle kakhulu etholakala ku-sebacic acid ne-2-ethylhexanol, esetshenziswa kabanzi ukuthuthukisa ukuguquguquka nokuqina kuma-polymers, ikakhulukazi ngaphansi kwezimo eziphansi kakhulu zokushisa.

Iyini i-Dioctyl Sebacate?

I-Dioctyl Sebacate (DOS) iwuketshezi olungenambala ukuya kokuphuzi okuphaphathekile, olunamafutha anefomula yemolekyuli ethi C₂₆H₅₀O₄ kanye nesisindo sengqamuzana esicishe sibe ngu- 426.68 g/mol . Ifaka i-volatility ephansi, ukusebenza kahle kwe-plasticizing ephezulu, nokusebenza okuvelele kwezinga lokushisa eliphansi. Abakhiqizi bavame ukuyihlanganisa namanye ama-plasticizer afana nama-phthalates ukuze uthole izakhiwo ezilinganiselwe ezinhlelweni ezifunwayo.

Izakhiwo ezibalulekile zomzimba namakhemikhali zihlanganisa:

• Ukubukeka : Uketshezi olunamafutha olucacile, olusobala

• Ukuminyana : ~0.914 g/cm³ ku-25°C

• Iphuzu Lokuncibilika : Cishe -48°C kuya ku-55°C

• Indawo yokubilisa : ~212°C ku-1 mmHg (noma 256°C ku-0.7 kPa)

• I-Flash Point : ≥215°C

• I-Solubility : Ayincibiliki emanzini; I-soluble ku-organic solvents njenge-ethanol, i-ether, ne-acetone

• Inkomba ye-Refractive : 1.450–1.455

Lezi zici zenza i-DOS izinze ngesikhathi sokucubungula izinga lokushisa eliphezulu kuyilapho igcina ukuguquguquka okuhle kakhulu ezindaweni ezibandayo.

Izinzuzo Eziyinhloko Ze-Dioctyl Sebacate Njenge-Plasticizer

I-Dioctyl Sebacate igqama phakathi kwama-ester plasticizers ngenxa yokusebenza kwayo okuphezulu kwezicelo ezisezingeni eliphansi lokushisa:

• Ukuguquguquka Kwezinga Eliphansi Okuhle Kakhulu - Igcina ukusebenziseka kalula kanye nomthelela wokumelana kuze kufike emazingeni okushisa aphansi kakhulu, yenza ama-adipate amaningi nama-phthalate ajwayelekile asebenze kahle kakhulu.

• I-Volatility Ephansi - Yehlisa ukulahleka ngesikhathi sokucubungula kanye nokusetshenziswa kwesikhathi eside, iqinisekisa ukuzinza komkhiqizo.

• Ukusebenza kahle kwePlasticizing - Iletha ukuthambisa okusebenzayo ngemithamo ephansi, ithuthukisa ukusebenza kahle kwezindleko.

• Ukushisa Okuhle, Ukukhanya, kanye Nokumelana Nesimo Sezulu - Ihlinzeka ngokufaka ugesi okuqinile kanye nokumelana nokukhishwa ngamanzi, insipho, noma okokuhlanza.

• Ukuvumelana - Isebenza kahle nge-PVC, i-vinyl chloride copolymers, ama-cellulose resins, ama-synthetic rubber, nezinhlelo ze-polyurethane.

Uma kuqhathaniswa nezinye ezifana ne-DOA (dioctyl adipate), i-DOS ivame ukunikeza ukuzinza okungcono kwesikhathi eside kanye nokufuduka okuphansi kwezinhlelo zokusebenza zeprimiyamu.

Izicelo Eziyinhloko ze-Dioctyl Sebacate (CAS 122-62-3)

Izimboni zisebenzisa kabanzi i-Dioctyl Sebacate emikhiqizweni edinga ukusebenza kwesimo sezulu esibandayo nokuqina:

• Imikhiqizo ye-PVC ne-Polymer — Amafilimu aguquguqukayo, amashidi, isikhumba sokwenziwa, izintambo, izintambo, nemikhiqizo yangaphandle echayeke emazingeni okushisa aphansi.

• Izimoto Nezokuthutha - Izingxenye zangaphakathi, izimpawu, namapayipi adinga ukuguquguquka esimweni sezulu esibandayo.

• Ama-Synthetic Rubber nama-Elastomers - Athuthukisa ukuqina kwezinga lokushisa eliphansi kuma-gaskets, amabhande, nezimpahla ezibunjiwe.

• Ama-coatings, Adhesives, and Inks - Ithuthukisa ukunwebeka nokugeleza ezinhlelweni ze-polyurethane nezingubo ezikhethekile.

• Ama-Lubricant and Specialty Fluids - Asetshenziswa kumafutha enjini asuselwa ku-ester, uketshezi olusebenza ngogesi, futhi njengengxenye kuketshezi oluthile lwamabhuleki noma amamodeli we-aerosol.

• Okunye Ukusetshenziswa — I-Plasticizer kuziqhumane (isb, i-C-4), izimonyo (njenge-emollient noma ifilimu yangaphambili), kanye nemishini yezokwelapha edinga ukusebenza kwezinga lokushisa eliphansi.

Iphrofayili yayo engenabo ubuthi kanye nokufuduka okuphansi kuyenza ifanelekele izinhlelo zokusebenza ezizwelayo, okufaka phakathi ukwakheka okuthobelana nokuthintana nokudla.

Ukucaciswa kobuchwepheshe (Okuvamile)

• Ukuhlanzeka (Okuqukethwe kwe-Ester) : ≥99.0%–99.6%

• I-Acid Inani : ≤0.1 mg KOH/g

• Umswakama : ≤0.1%

• Umbala (Pt-Co) : ≤30

• I-Kinematic Viscosity : 11–12 mm²/s ku-40°C

Ukucaciswa ngokwezifiso kuyatholakala uma kuceliwe ukuze kuhlangatshezwane namazinga athile omkhakha.

Kungani Khetha i-Dioctyl Sebacate Yokwakhiwa Kwakho?

Kubakhiqizi abafuna ukusebenza okuthembekile kwezinga lokushisa eliphansi ngaphandle kokufaka engozini ukuzinza kokushisa noma izakhiwo zikagesi, i-Dioctyl Sebacate (DOS, CAS 122-62-3) iletha imiphumela engaguquki. Inhlanganisela yayo yokungaguquguquki okuphansi, ukusebenza kahle okuphezulu, nokuhambisana okuhle kakhulu kusiza ukukhiqiza imikhiqizo yokugcina eqinile, eguquguqukayo esebenza ngokuthembekile ezindaweni ezinokhahlo.
