Phthalic anhydride (PA) CAS TSIS .: 85-44-9

Cov lus piav qhia luv luv:

Khoom Txheej Txheem

Phthal anhydride (PA) yog qhov tseem ceeb organic tshuaj raw khoom, feem ntau tsim los ntawm oxidation ntawm ortho-xylene lossis naphtalene lossis naphtalene lossis naphthalene. Nws zoo li yog tus dawb crystalline khoom nrog ib tug me ntsis khib nyiab tsw. PA yog dav siv nyob rau hauv kev tsim cov tshuab yas, unsaturated polyester resins, alkyde polyester, thiab pigments, ua rau nws yog qhov tseem ceeb hauv nruab nrab hauv kev lag luam tshuaj.

Cov Nta Tseem Ceeb

• Cov siab reactivity:Pa muaj cov pab pawg uas muaj cov rog, uas yooj yim hnov ​​noj nrog cawv, amines, thiab lwm yam sib xyaw ua ke los ua cov khoom siv tshuab hluav taws xob lossis chaw nyob.
• Zoo solubility:Soluble hauv dej kub, dej cawv, neeg muaj neeg ua phem, thiab lwm yam kuab tshuaj organic.
• Stability:Ruaj khov nyob rau hauv cov kev mob qhuav tab sis hydrolyzes maj mam mus rau phthalic acid nyob rau hauv lub xub ntiag dej.
• Versatility:Siv nyob rau hauv cov synthesis ntawm ntau cov khoom siv tshuaj lom neeg, ua rau nws muaj ntau yam.

Cov Ntawv Thov

1. Yas hli:Siv los tsim cov philalate esters (piv txwv li, dop, dbp), uas yog siv dav hauv PVC cov khoom lag luam los txhim kho kom tau yooj yim thiab ua kom tiav.
2. Unsaturated polyester resins:Siv hauv cov khoom siv ntawm cov fiberglass, txheej, thiab cov nplaum, muab cov tshuaj kho kom zoo nkauj thiab cov tshuaj tiv thaiv.
3. Alkyd Resins:Siv cov xim tha xim, txheej, thiab cov varnishes, muab cov adhesion zoo thiab ci.
4. Dyes thiab cov xim:Ua haujlwm rau hauv nruab nrab hauv synthesis ntawm anthraquinone dyes thiab pigments.
5. Lwm Yam Kev Siv:Siv nyob rau hauv kev tsim cov kws tshuaj nruab nrab, tshuaj tua kab, thiab tsw qab.

Ntim & Cia

• Ntim:Muaj nyob rau hauv 25 kg / hnab, 500 kg / hnab, lossis tuj lub hnab. Muaj cov kev xaiv lag luam muaj nyob rau thaum thov.
• Cia:Khaws rau hauv qhov chaw txias, qhuav, thiab muaj cua zoo. Zam kev sib cuag nrog noo noo. Pom zoo cia khoom kub: 15-25 ℃.

Kev Nyab Xeeb & Kev Txiav Txim Siab

• Voos:Pa yog khaus rau daim tawv nqaij, ob lub qhov muag, thiab ua pa. Cov cuab yeej tiv thaiv kom raug (xws li hnab looj tes, goggles, ua pa) yuav tsum hnav thaum tuav.
• Flammability:Combustible tab sis tsis tau muaj nplaim taws heev. Tseg kom deb ntawm cov nplaim taws thiab qhov kub.
• Cuam tshuam ib puag ncig:Muab cov ntaub pua pov tseg raws li kev cai ib puag ncig hauv zos kom tiv thaiv kev ua qias tuaj.
