1,2-Propyleneglycol Diacetate Propylene Glycol Diacetate PGDA CAS 623-84-7
Propylene Glycol Diacetate (PGDA, CAS 623-84-7), oo sidoo kale loogu yeero 1,2-Propanediol diacetate, waa dareere diester ah oo aan midab lahayn oo deegaanka u fiican oo karkaraya oo leh ur yar oo ester ah. Nadiif ah ≥99.0%. Waxay leedahay heer uumi-bax dhexdhexaad ah iyo dabacsanaan aad u fiican oo loogu talagalay resins-ka acrylic, PU, alkyd iyo nitrocellulose. Iyada oo ah beddel wanaagsan oo loogu talagalay cyclohexanone, isophorone, PMA iyo DBE, waxaa si weyn loogu isticmaalaa dahaarka baabuurta, dahaarka gariiradda, khad maaskaro alxan PCB, dhejisyo ku salaysan biyaha, nadiifinta saxda ah ee elektaroonigga ah iyo warshadda macdanta sida adkeyaha ester-ka dabiiciga ah. Waxaa loo soo diraa xamuul guud. Muddada kaydinta: 12 bilood ka dib kaydinta qabow ee la xiray.

1. Deegaanka kaydinta: Ku kaydi bakhaar xiran, qabow, qalalan oo hawo fiican leh; heerkulka kaydinta ee lagu taliyay waa ≤ 30℃, waana in laga fogaadaa qorraxda tooska ah.
2. Kaydinta go'doominta: Ka fogow ololka furan iyo ilaha kulaylka heerkulka sare leh; ha ku kaydin oksaydhyo xooggan, asiidhyo xooggan iyo alkaliyo xooggan si looga hortago falcelinta.
3. Shuruudaha Baakadaha: Ku kaydi foostooyinkii asalka ahaa ee la shaabadeeyey si looga hortago uumiga iyo qoyaanka soo galaya; adkee daboolka foosto si looga fogaado daadashada.
4. Shuruudaha is dulsaarka tuulmooyinka: Dhig 220kg oo foosto bir ah / foosto balaastig ah oo ku rid baalasheeda, si adag u xidh si looga hortago in la rogo; hubi in dabaqa bakhaarka si habboon looga ilaaliyo biyaha.
5. Muddada kaydinta: Iyada oo aan la furin oo aan waxyeelloobin, cimriga kaydinta ee xaaladaha kaydinta ee kor ku xusan waa 12 bilood. Isticmaal badeecada sida ugu dhakhsaha badan ka dib marka la furo si aad u yarayso uumiga iyo nuugista biyaha.
