Propargyl-PEG5-alcohol (CAS#87450-10-0)

Mawu Oyamba

Propynyl-tetraethylene glycol, yomwe imadziwikanso kuti polypropynyl alcohol, ndi polima yomwe ili ndi magulu ogwira ntchito a propynyl. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha propynyl-tetrameric glycol:

Ubwino:

- Propynyl-tetraethylene glycol ndi madzi opanda mtundu mpaka achikasu kapena olimba.

- Ili ndi kusungunuka kwabwino ndipo imasungunuka m'madzi ambiri osungunulira ndi madzi.

Gwiritsani ntchito:

- Itha kugwiritsidwa ntchito ngati polima modifier, viscosity modifier, impregnation wothandizila ndi thickener, etc.

Njira:

- Proynyl-tetraethylene glycol imatha kupangidwa munjira ziwiri, pomwe magulu ogwira ntchito a propynyl amayamba kulowetsedwa mu unyolo wa polyethylene glycol pogwiritsa ntchito propynylating agent, kenako ndi polymerization.

- Ma polymerization amakhudzidwa nthawi zambiri ndi zopangira zitsulo monga mchere wa siliva kapena platinamu.

Zambiri Zachitetezo:

- Propynyl-tetraethylene glycol ndi yoyaka ndipo iyenera kupewedwa kuti isakhudzidwe ndi malawi otseguka kapena zinthu zotentha kwambiri.

- Valani magolovesi oteteza ndi maso kuti mupewe kukhudzana ndi khungu komanso pokoka mpweya mukamagwira ntchito.

- Iyenera kusungidwa pamalo ozizira, mpweya wabwino komanso kutali ndi oxidizing agents.

- Mukamagwiritsa ntchito ndikugwiritsa ntchito propynyl-tetrameric glycol, njira zogwirira ntchito zotetezeka ndi malamulo oyenera ziyenera kuwonedwa.
