Phthalic Anhydride 99.5% PA

Phthalic Anhydride 99.5% waxay keentaa tayada joogtada ah ee caagagga, resinka, iyo wax soo saarka dheeha adduunka oo dhan. CAS 85-44-9 cyclic anhydride (PA, Isobenzofuran-1,3-dione, Benzene-1,2-dicarboxylic Anhydride) waxay ku guulaysataa ≥99.5% nadiifnimada GC oo leh ≤0.1% phthalic acid iyo ≤0.05% dib-u-celinta balaastiigga dib-u-celinta.

Maaddaama ay tahay tan labaad ee ugu weyn ee dhexdhexaadka ah ee dabiiciga ah ee caalamiga ah, phthalic anhydride waxay u adeegtaa quudinta asaasiga ah ee dioctyl phthalate (DOP) iyo diisononyl phthalate (DINP) balaastikada ee farsamaynta PVC, oo ah qayb muhiim ah oo loogu talagalay alkyd iyo polyester-ka aan nadiifka ahayn ee daboolka iyo isku-dhafka, dhexdhexaadiyaha iyo isku-dhafka hore phthalimide iyo anthranilic acid ee isku-darka dawooyinka. Giraanta anhydride-ka fal-celisa wuxuu si hufan ugu furmaa aalkolada iyo aminnada hoostooda xaalado khafiif ah.

Heerarka la heli karo: Warshadaha 99.5% (dhalalay ama dhalaalay), Nadiifin sare 99.8% (<0.05% aashito), Midab-hooseeya (APHA ≤20), Heerka kulaylka u adkaysta ee esterification heerkul sare.

Baakadaha: 25kg/bac bacaha kraft bac oo leh PE liner (qaab jajab); 500kg bacaha bulk ama haamaha ISO (dhalalay, 60-70°C) ee isticmaalayaasha mugga sare leh. Barta adag ee 131 ° C; ku qabo shayga dhalaalay oo leh xariiqyo kulul iyo bambooyin.

Xakamaynta Muhiimka ah: Adag heerkulka deegaanka; boodhka ka xanaajiso oo dareensiiya habka neefsashada. Foomka dhalaalay wuxuu keenaa gubasho kulayl daran. GAARSIIN diiwaan gashan; TSCA ayaa ku taxan; Soo jeedinta California 65 (sumowga horumarka). SDS dhamaystiran oo leh ka-hortagga qaraxa boodhka, borotokoolka maaraynta dhalaalaysa, iyo kinetics-ka-saarista.

Sahayda: U dhoofinta tooska ah ee Shiinaha, India, USA, Germany, Brazil, iyo 70+ suuqyada. COA buuxa oo leh nambarka aashitada, qiimaha saponification, midabka, iyo barta qaboojinta.

Codso qiimahaaga Phthalic Anhydride 99.5% 24 saacadood gudahood — sahay dhalaalid badan ama dhalaal ah, muunado heer sare ah oo nadiif ah, iyo qalabaynta balaastiigga taageero farsamo ayaa la heli karaa.

Shirkaddayadu waxay si qoto dheer ugu hawlan tahay warshadaha kiimikada waxayna inta badan wax ka qabataa noocyo kala duwan oo alaabta ceeriin kiimikaad ah sida surfactants, kiimikooyinka ganaaxa ee saliidda, alaabta ceeriin ee aasaasiga ah, dareerayaasha organic, dhexdhexaadinta dawooyinka iyo sunta cayayaanka, wakiilada daaweynta biyaha, iyo cuntada lagu daro. Alaabooyinkeeda ayaa si weyn looga isticmaalaa warshado kala duwan.

Kiimikadayada sida aadka ah loo iibiyo waxaa ka mid ah dareerayaasha warshadaha iyo kuwa dhexdhexaadka ah ee kiimikaad, sida Alcohols, Esters, Precursors, Bacrimiyeyaasha NPK-Biyo-Milan, iyo Acid-Ester Solvents. Alaabooyinkani waxay ka kooban yihiin sahay deggan, nadiifnimo la isku halayn karo, iyo heerar tayo leh oo joogto ah. Weydiinta waa la soo dhawaynayaa.
