Isingeniso

I-Propynyl-tetraethylene glycol, eyaziwa nangokuthi i-polypropynyl alcohol, i-polymer equkethe amaqembu asebenzayo we-propynyl. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-propynyl-tetrameric glycol:

Ikhwalithi:

- I-Propynyl-tetraethylene glycol iwuketshezi olungenambala ukuya kokuphuzi noma oluqinile.

- Inoncibilika kahle futhi iyancibilika kuzincibilikisi eziningi zemvelo nasemanzini.

Sebenzisa:

- Ingasetshenziswa njenge-polymer modifier, i-viscosity modifier, i-ejenti yokukhulelwa kanye ne-thickener, njll.

Indlela:

- I-Proynyl-tetraethylene glycol ingahlanganiswa ngenqubo yezinyathelo ezimbili, lapho amaqembu asebenzayo e-propynyl eqala ukungeniswa ochungechungeni lwe-polyethylene glycol kusetshenziswa i-propynylating agent, elandelwa yi-polymerization.

- Ukusabela kwe-polymerization kuvame ukwenziwa ama-catalysts ensimbi njengesiliva noma usawoti weplatinamu.

Ulwazi Lokuphepha:

- I-Propynyl-tetraethylene glycol iyavutha futhi kufanele igwenywe ukuthintana namalangabi avulekile noma izinto ezishisa kakhulu.

- Gqoka amagilavu okuvikela afanelekile namehlo ukuze ugweme ukuthintana kwesikhumba nokuhogela lapho usebenza.

- Kufanele igcinwe endaweni epholile, enomoya omuhle futhi kude nama-oxidizing agents.

- Uma usebenzisa futhi uphatha i-propynyl-tetrameric glycol, izinqubo zokusebenza eziphephile kanye nemithethonqubo efanele kufanele igcinwe.

Okwedlule: 1-ethyl-2-cyanoiminoimidazolidine (CAS#49552-13-8)

Olandelayo: 4,5-Dimethyl thiazole (CAS#3581-91-7)
