Propylene carbonate ndi madzi Opanda utoto kapena achikasu pang'ono. Ndizogulitsa zogulitsa zotentha.
Tili ndi mafakitale 2, omwe ali ku Shandong ndi Jiangsu, omwe amatuluka pachaka matani 20,000 a propylene carbonate.
Pali katundu wokwanira kwa makasitomala onse, ndipo amatha kutumiza mwachangu ndi kuyitanitsa kulikonse.

* Kwa Kugwiritsa Ntchito motere
Izi zitha kugwiritsidwa ntchito ngati zosungunulira zapamwamba kwambiri zochotsera mpweya wa carbon dioxide ku mafuta a petroleum, petroleum cracking gas, mafuta akumunda gasi ndi kupanga ammonia yaiwisi gasi; m'makampani opanga nsalu, amatha kugwiritsidwa ntchito ngati chothandizira komanso chowongolera mitundu pazingwe zopangira; mu mabatire M'makampani, itha kugwiritsidwa ntchito ngati sing'anga yabwino kwambiri yamabatire a lithiamu; m'makampani a polima, atha kugwiritsidwa ntchito ngati chosungunulira ma polima.
【Gwiritsani ntchito 1】
Zopaka Zochiritsira za UV ndi Inks
【Gwiritsani ntchito 2】
Amagwiritsidwa ntchito ngati madzi osasunthika komanso osungunulira pa chromatography ya gasi, komanso amagwiritsidwa ntchito popanga ma polima apamwamba kwambiri.
【Gwiritsani ntchito 3】
Amagwiritsidwa ntchito ngati zosungunulira wamafuta, kupota zosungunulira, olefin, onunkhira hydrocarbon extractant, carbon dioxide absorber, dispersant kwa utoto sungunuka madzi ndi inki, etc.
【Gwiritsani ntchito 4】
Izi ndi zosungunulira za polar, zomwe zimagwiritsidwa ntchito ngati pulasitiki, zosungunulira zopota, utoto wosungunuka m'madzi ndi dispersant pulasitiki. Itha kugwiritsidwanso ntchito ngati chopangira mafuta osungunulira mafuta ndi ma olefin ndi ma hydrocarbon onunkhira. Propylene carbonate monga electrolyte ya batri imatha kupirira kuwala, kutentha ndi kusintha kwa mankhwala. Ilinso ndi ntchito zina mu geological mineral processing ndi analytical chemistry. Kuphatikiza apo, propylene carbonate imathanso kulowa m'malo mwa phenolic resin ngati zomatira zamatabwa, komanso kugwiritsidwa ntchito popanga dimethyl carbonate.
【Gwiritsani ntchito 5】
Propylene carbonate (108-32-7) imagwiritsidwa ntchito ngati chosungunulira chapamwamba kwambiri chochotsera mpweya woipa ku mafuta amafuta, mafuta ophwanyira mafuta, gasi wamafuta am'munda ndi gasi wopangira ammonia, komanso angagwiritsidwe ntchito ngati pulasitiki, kupota zosungunulira kapena zosungunulira. Utoto wosungunuka m'madzi, zothira utoto wa pigment, zosungunulira zamafuta ndi zotulutsa za olefin ndi ma hydrocarbon onunkhira; itha kugwiritsidwanso ntchito ngati sing'anga yabwino kwambiri yamabatire a lithiamu mumakampani a batri
【Gwiritsani ntchito 6】
Monga zosungunulira zamphamvu kwambiri, zitha kugwiritsidwa ntchito pochotsa mpweya woipa kuchokera ku mafuta a petroleum, gasi wosweka, mafuta akumunda wamafuta ndi gasi wopangira ammonia. Itha kugwiritsidwanso ntchito ngati plasticizer, zosungunulira zozungulira kapena utoto wosungunuka m'madzi, dispersant pigment, zosungunulira zamafuta ndi Extractant za olefins ndi aromatics.
* Mikhalidwe yosungira
Sungani m'nyumba yosungiramo zinthu zoziziritsa kukhosi komanso mpweya wokwanira. Khalani kutali ndi gwero la moto ndi kutentha. ziyenera kusungidwa kutali ndi oxidizer, osasunga pamodzi. Okonzeka ndi mitundu yoyenera komanso kuchuluka kwa zida zozimitsa moto. Malo osungira ayenera kukhala ndi zida zotulutsa mwadzidzidzi komanso zida zoyenera zosungira.
Mankhwalawa amadzazidwa mu ng'oma zachitsulo ndikusungidwa pamalo ozizira komanso opanda mpweya wabwino, kutali ndi komwe kuli moto. Kusungirako ndi zoyendera malinga ndi malamulo a mankhwala oyaka moto.
*Kukhazikika
1. Pewani kukhudzana ndi ma okosijeni amphamvu.
Katundu Wamankhwala: Kuwola pang'ono kumachitika pamwamba pa 200 ℃, ndipo asidi pang'ono kapena zamchere zimatha kulimbikitsa kuwonongeka. Propylene glycol carbonate imathanso kukumana ndi hydrolysis mwachangu kutentha kwa chipinda pamaso pa ma acid, makamaka maziko.
2. Kuopsa kwa mankhwalawa sikudziwika. Samalani kupewa poizoni wa phosgene panthawi yopanga. Malo ogwirira ntchito akuyenera kukhala ndi mpweya wabwino ndipo zida ziyenera kutsekedwa. Oyendetsa ayenera kuvala zida zodzitetezera.
3. Zimakhala m'masamba a fodya ochiritsidwa ndi flue ndi utsi.
