Phthalic Anhydride Rau Plasticizer
CAS Nr .: 85-44-9
Cov mis mos molecular: C8H4O3
Molecular Luj: 148.12
Lub cev lub cev: rab koob dawb -zoo li crystals
Ntim: 25KG / hnab
Khoom Description
Phthalic anhydride (PA) tsis yog plasticizer ntawm nws tus kheej, tab sis nws yog ib qho tseem ceeb raw khoom nyob rau hauv zus tau tej cov phthalate ester plasticizers. Los ntawm cov tshuaj tiv thaiv esterification, PA tau hloov mus rau hauv cov tebchaw xws li dioctyl phthalate (DOP) thiab diisononyl phthalate (DINP). Cov phthalate esters no yog cov khoom siv ntxiv siv los txhim kho qhov yooj yim, kev ua tau zoo, thiab ua haujlwm ntev ntawm cov ntaub ntawv polymer, tshwj xeeb yog PVC.

Feem ntau Phthalate Ester Plasticizers
Phthalic anhydride rau plasticizerntau lawm yog siv los tsim ntau yam phthalate esters tsim los rau kev ua haujlwm sib txawv. Dioctyl phthalate (DOP), tseem hu ua DEHP, yog ib qho dav siv dav dav -lub hom phiaj plasticizer thiab sawv cev rau cov khoom ntim loj tshaj plaws vim nws qhov sib npaug thiab cov yam ntxwv ua haujlwm. Cov molecular siab dua- hnyav plasticizers xws li DINP thiab DIDP yog qhov zoo dua qhov uas yuav tsum tau txhim kho kev ruaj khov, txo qis qis, thiab ntev - lub sijhawm ua haujlwm yuav tsum tau ua. Cov qib tshwj xeeb suav nrog DBP thiab BBP feem ntau siv rau hauv cov nplaum, cov ntaub ntawv hauv pem teb, thiab cov sealants, qhov tshwj xeeb yooj yooj yim, adhesion, thiab kev tswj kev ua haujlwm tseem ceeb.
Daim ntawv ceeb toom kev noj qab haus huv & kev tswj hwm
Raws li qee yam qis -molecular- hnyav phthalates xws li DEHP tau raug cais raws li cov tshuaj tua kab mob, ntau lub tuam txhab tau hloov mus rau siab dua -molecular- hnyav phthalates lossis tsis yog - phthalate plasticizer lwm txoj. Txawm hais tias cov kev hloov pauv no, phthalic anhydride tseem yog thawj thiab feem ntau siv cov khoom pib hauv kev tsim cov yas yas.
FAQ rau ZnCl2 Catalyst
Q: Dab tsi yog lub ntsiab impurities hauv cov khoom?
A: Cov khoom lag luam tswj hwm qis qis ntawm impurities, suav nrog hlau (Fe Less dua lossis sib npaug li 0.0005%), sulfate (SO₄²⁻ Tsawg dua lossis sib npaug rau 0.001%), thiab acid-insoluble teeb meem tsawg dua lossis sib npaug li 0.02%, kom ntseeg tau tias kev ua haujlwm zoo ib yam hauv cov txheej txheem kev lag luam.
Q: Dab tsi yog cov dej noo ntawm ZnCl2 Catalyst?
A: Cov ntsiab lus noo noo yog tswj tau tsawg dua lossis sib npaug li 0.3%, uas pab tswj kev ruaj ntseg thiab ua kom ntseeg tau tias muaj kev cuam tshuam zoo hauv kev siv tshuaj lom neeg lossis metallurgical.
Q: Hom kev ntim khoom twg muaj?
A: Lub ZnCl2 Catalyst yog muab rau hauv 25 kg hnab, haum rau kev txiav txim ntau thiab optimized rau thoob ntiaj teb shipping thiab tuav.
Q: Cov khoom no puas raug cais raws li cov khoom siv phom sij rau kev thauj mus los?
A: Yog lawm, nws raug cais raws li UN 2331, Chav Kawm 8, thiab tuaj yeem xa khoom nyab xeeb thoob ntiaj teb ua raws li cov cai tswj kev phom sij.
Q: Cov khoom no puas tsim nyog ua cov khoom siv rau cov khoom siv tshuaj lom neeg?
A: Yog lawm. Nws cov purity siab thiab cov ntsiab lus tsis tshua muaj hlau ua rau nws zoo tagnrho raws li Lewis acid catalyst rau ntau yam organic synthesis tshwm sim.
