Khoom Taw Qhia
Phthalic anhydrideyog ib qho organic compound nrog cov tshuaj formula C₈H₄O₃. Nws yog cyclic acid anhydride tsim los ntawm lub cev qhuav dej ntawm phthalic acid molecule. Nws zoo nkaus li cov hmoov dawb crystalline hmoov. Nws yog ib qho tseem ceeb raw khoom nyob rau hauv cov organic chemical industries thiab ua hauj lwm raws li ib tug tseem ceeb nruab nrab ntawm zus tau tej cov phthalate plasticizers, coatings, saccharin, dyes, thiab lwm yam organic tebchaw.

Khoom siv
Phthalic anhydridefeem ntau yog siv rau hauv kev tsim cov phthalate-based plasticizers, uas suav txog li 60% ntawm nws daim ntawv thov tag nrho. Dyes thiab pleev xim rau kwv yees li 25%, thaum unsaturated resins thiab lwm yam khoom muaj li 15%.
Kev tsim cov yas yas: PA reacts nrog cawv los tsim phthalic acid esters, xws li dibutyl phthalate (DBP) thiab dioctyl phthalate (DOP) uas paub txog lawv lub teeb xim, tsis muaj toxicity, zoo heev hluav taws xob, thiab tsis tshua muaj volatility, feem ntau yog siv los ua plasticizers nyob rau hauv lub plastics kev lag luam, tshwj xeeb tshaj yog rau polyvinyl chloride (PVC).
Synthetic Resins: Nws kuj yog siv rau hauv kev sib txuas ntawm unsaturated polyester resins thiab alkyd resins. Cov resins no tau siv dav hauv cov txheej txheem, cov nplaum, cov khoom siv fiberglass, thiab cov ntawv luam ntawv, muab cov khoom siv zoo heev thiab tshuaj lom neeg.
Dyes thiab Pigments: Raws li qhov nruab nrab tseem ceeb hauv kev tsim cov xim, nws yog siv los tsim ntau yam xim, suav nrog anthraquinone derivatives thiab phthalocyanine xiav, uas yog qhov tseem ceeb rau textiles, luam ntawv, thiab lwm yam lag luam.
Khoom ntim & Cia
1. Ntim Ntim (25kg / hnab):
20 MT / 20 FCL tsis muaj pallets
14-18 MT/20 FCL nrog pallets (nyob ntawm cov khoom los ntawm lub Hoobkas).)
Txawm tias muaj pallets los yog tsis, 20-27 MT/40 FCL (nyob ntawm qhov hnyav txwv ntawm qhov chaw nres nkoj)
2.Ntim Ntim (500kg / hnab):
Nrog pallets lossis tsis, 15 MT / 20 FCL
Nws raug nquahu kom siv 40 FCL rau kev ntim khoom loj. Qhov no tso cai rau lub thawv ntim 26 txog 27 tons MAX
FAQ
Q: Thaum xa tawm phthalic anhydride, nws puas raug cais raws li cov khoom lag luam lossis cov khoom txaus ntshai?
A: Peb cov phthalic anhydride muaj cov ntsiab lus ntawm cov txiv neej anhydride (MA) tsawg dua 0.05%, yog li nws raug cais raws li cov khoom thauj dav dav (cov khoom tsis txaus ntshai) rau kev thauj mus los thiab tsis tas yuav ntim khoom txaus ntshai. Peb muaj cov ntaub ntawv pov thawj cuam tshuam (cov ntawv pov thawj khoom tsis txaus ntshai, thiab lwm yam) muaj.
Q: Dab tsi yog qhov tseem ceeb ntawm PA OX-BASE thiab PA NP-BASE?
A: Phthalic anhydride OX-BASE feem ntau yog siv los tsim cov resins, plastics, dyes, thiab pigments. NP-BASE tsuas yog siv rau hauv kev sib txuas ntawm dyes, pigments, nrog rau qee yam tshwj xeeb resins thiab catalysts.
