Txheej Txheem Cej Luam Khoom

Phthalic Anhydride (PA) yog ib yam khoom siv organic tseem ceeb, feem ntau yog tsim los ntawm kev oxidation ntawm ortho-xylene lossis naphthalene. Nws zoo li cov khoom dawb crystalline nrog me ntsis tsw ntxhiab khaus. PA yog siv dav hauv kev tsim cov plasticizers, unsaturated polyester resins, alkyd resins, dyes, thiab pigments, ua rau nws yog ib qho tseem ceeb hauv kev lag luam tshuaj lom neeg.

Cov Nta Tseem Ceeb

• Kev Ua Haujlwm Siab:PA muaj cov pab pawg anhydride, uas yooj yim cuam tshuam nrog cov cawv, amines, thiab lwm yam sib xyaw ua ke los tsim cov esters lossis amides.
• Kev yaj zoo:Yaj hauv dej kub, cawv, ethers, thiab lwm yam organic solvents.
• Kev Ruaj Ntseg:Ruaj khov nyob rau hauv cov xwm txheej qhuav tab sis hydrolyzes qeeb rau phthalic acid nyob rau hauv lub xub ntiag ntawm dej.
• Kev siv tau ntau yam:Siv rau hauv kev tsim ntau yam khoom siv tshuaj, ua rau nws muaj ntau yam zoo.

Cov ntawv thov

1. Cov khoom yas:Siv los tsim cov phthalate esters (piv txwv li, DOP, DBP), uas siv dav hauv cov khoom PVC los txhim kho kev ywj pheej thiab kev ua haujlwm.
2. Cov Resins Polyester Tsis Muaj Kev Ruaj Ntseg:Siv rau hauv kev tsim cov fiberglass, coatings, thiab adhesives, muab cov khoom siv kho tshuab zoo heev thiab tshuaj lom neeg tsis kam.
3. Cov roj alkyd:Siv rau hauv cov xim pleev, cov tshuaj pleev xim, thiab cov kua roj vanish, muab kev nplaum zoo thiab ci ntsa iab.
4. Cov Xim thiab Cov Xim:Ua haujlwm ua ib qho nruab nrab hauv kev tsim cov anthraquinone dyes thiab pigments.
5. Lwm Cov Ntawv Thov:Siv rau hauv kev tsim cov tshuaj intermediates, tshuaj tua kab, thiab tshuaj tsw qab.

Ntim Khoom & Cia Khoom

• Ntim:Muaj nyob rau hauv 25 kg/hnab, 500 kg/hnab, lossis ton hnab. Cov kev xaiv ntim khoom raws li qhov xav tau muaj.
• Kev Khaws Cia:Khaws cia rau qhov chaw txias, qhuav, thiab muaj cua nkag tau zoo. Tsis txhob cia kom raug dej noo. Qhov kub thiab txias uas pom zoo kom khaws cia: 15-25 ℃.

Kev Nyab Xeeb & Kev Xav Txog Ib puag ncig

• Kev khaus:PA ua rau khaus tawv nqaij, qhov muag, thiab lub cev ua pa. Yuav tsum hnav cov khoom siv tiv thaiv zoo (piv txwv li, hnab looj tes, tsom iav, thiab lub tshuab ua pa) thaum tuav.
• Kev kub hnyiab:Yooj yim hlawv tab sis tsis yooj yim hlawv. Khaws cia kom deb ntawm cov nplaim taws qhib thiab qhov kub siab.
• Kev Cuam Tshuam Ib puag ncig:Pov tseg cov khoom pov tseg raws li cov cai ib puag ncig hauv zos kom tiv thaiv kev ua qias tuaj.
