Tetrachloroethylene, yomwe imadziwikanso kutiperchloroethylene, ndi mankhwala achilengedwe okhala ndi formula ya mankhwala C2Cl4. Ndi madzi opanda mtundu, osasungunuka m'madzi ndipo amatha kusakanikirana mu ethanol, ether, chloroform ndi zinthu zina zachilengedwe. Amagwiritsidwa ntchito makamaka ngati zosungunulira zachilengedwe komanso chotsukira chouma, ndipo angagwiritsidwenso ntchito ngati zosungunulira zomatira, zosungunulira zitsulo, zotsukira utoto, zochotsa tizilombo komanso zotulutsa mafuta. Angagwiritsidwenso ntchito popanga zinthu zachilengedwe.
Kapangidwe ka mankhwala:Madzi owonekera opanda mtundu, okhala ndi fungo lofanana ndi ether. Amatha kusungunula zinthu zosiyanasiyana (monga rabara, utomoni, mafuta, aluminiyamu chloride, sulfure, ayodini, mercury chloride). Sakanizani ndi ethanol, ether, chloroform, ndi benzene. Sungunuka m'madzi okhala ndi voliyumu pafupifupi nthawi 100,000.
Ntchito ndi ntchito:
Mu mafakitale, tetrachloroethylene imagwiritsidwa ntchito kwambiri ngati zosungunulira, kupanga zinthu zachilengedwe, kuyeretsa pamwamba pa zitsulo ndi chotsukira chouma, desulfurizer, ndi njira yosamutsira kutentha. Imagwiritsidwa ntchito pachipatala ngati chotsukira nyongolotsi. Ndiwonso wothandiza popanga trichloroethylene ndi organics zomwe zili ndi fluorine. Anthu ambiri amatha kukhudzidwa ndi kuchuluka kochepa kwa tetrachloroethylene kudzera mumlengalenga, chakudya ndi madzi akumwa. Tetrafloroethylene ya mitundu yambiri ya inorganic ndi organic Chemicalbook kuphatikiza ili ndi kusungunuka kwabwino, monga sulfure, ayodini, mercury chloride, aluminiyamu trichloride, mafuta, rabara ndi resin, kusungunuka kumeneku kumagwiritsidwa ntchito kwambiri ngati chotsukira chochotsa mafuta m'chitsulo, chochotsera utoto, chotsukira chouma, chosungunulira rabara, chosungunulira inki, sopo wamadzimadzi, ubweya wapamwamba ndi chotsukira nthenga; Tetrachloroethylene imagwiritsidwanso ntchito ngati chotsukira tizilombo (piritsi la hookworm ndi ginger); Chotsukira chomaliza chokonzera nsalu.
Ntchito:Chimodzi mwa ntchito zazikulu za perchloroethylene ndi monga organic solvent ndi dry cleaner. Mphamvu ya organic composite yosungunula zinthu zachilengedwe popanda kuwononga nsalu imapangitsa kuti ikhale yoyenera kwambiri pa zovala zotsukira zouma. Ntchito zina za organic ikuphatikizapo kugwiritsa ntchito ngati solvent ya zomatira, chitsulo chochotsa mafuta, desiccant, chochotsa utoto, chothamangitsa tizilombo, ndi chochotsera mafuta. Kuphatikiza apo, ingagwiritsidwenso ntchito popanga organic, zomwe zimapangitsa kuti ikhale gawo lofunikira kwambiri mumakampani opanga mankhwala.
Perchloroethylene ili ndi zinthu zosiyanasiyana zomwe zimapangitsa kuti ikhale yogwiritsidwa ntchito bwino kwambiri m'mafakitale ambiri. Mphamvu zake zabwino zosungunulira zimapangitsa kuti ikhale yothandiza kwambiri pakusungunula mafuta, mafuta, mafuta, ndi sera. Kuphatikiza apo, imagwira ntchito bwino pochotsa zinthu zomata, zomwe zimapangitsa kuti ikhale yosungunulira bwino kwambiri. Kuwira kwake kwambiri kumapangitsanso kuti ikhale yabwino kwambiri pakugwiritsa ntchito komwe kumafuna kutentha kwambiri.
Kusinthasintha kwa Perchloroethylene kumapangitsa kuti ikhale chinthu chodziwika bwino m'makampani oyeretsa amalonda. Imagwiritsidwa ntchito ngati chosungunulira chouma, ndipo mawonekedwe ake abwino oyeretsera amachititsa kuti ikhale yoyenera kutsuka makapeti, mipando, ndi nsalu zina. Imagwiritsidwanso ntchito kuyeretsa zida zamagalimoto, mainjini, ndi makina amafakitale, zomwe zimapangitsa kuti ikhale imodzi mwa zosungunulira zomwe zimagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana.
Zitetezo zogwirira ntchito:Kugwira ntchito motsekedwa, kulimbitsa mpweya wabwino. Ogwira ntchito ayenera kuphunzitsidwa mwapadera ndikutsatira mosamala njira zogwirira ntchito. Akulimbikitsidwa kuti ogwira ntchito azivala chigoba cha gasi chodzipangira (theka la chigoba), magalasi oteteza chitetezo cha mankhwala, zovala zoteteza mpweya, ndi magolovesi oteteza mankhwala. Sungani kutali ndi moto, gwero la kutentha, musasute fodya kuntchito. Gwiritsani ntchito makina ndi zida zopumira mpweya zomwe sizingaphulike. Pewani nthunzi kuti isatuluke mumlengalenga wa kuntchito. Pewani kukhudzana ndi alkali, ufa wachitsulo wogwira ntchito, chitsulo cha alkali. Mukagwira ntchito, kunyamula ndi kutsitsa zinthu pang'ono kuyenera kuchitika kuti mupewe kuwonongeka kwa ma CD ndi ziwiya. Mukhale ndi zida zosiyanasiyana komanso kuchuluka kwa zida zozimitsira moto komanso zida zochizira mwadzidzidzi zomwe zimatuluka. Chidebe chopanda kanthu chingakhale ndi zotsalira zovulaza.
Malangizo Osungira Zinthu:Nyumba yosungiramo zinthu imakhala ndi mpweya wokwanira komanso youma pa kutentha kochepa; Sungani padera ndi ma oxidants ndi zowonjezera chakudya; Kusungirako kuyenera kuwonjezeredwa ndi chokhazikika, monga hydroquinone. Sungani m'nyumba yosungiramo zinthu yozizira komanso yopatsa mpweya. Sungani kutali ndi moto ndi kutentha. Phukusilo liyenera kutsekedwa ndipo lisakhudze mpweya. Liyenera kusungidwa padera ndi alkali, ufa wachitsulo wogwira ntchito, chitsulo cha alkali, mankhwala odyedwa, ndipo musasakanize malo osungiramo zinthu. Lili ndi mitundu yosiyanasiyana ndi kuchuluka kwa zida zozimitsira moto. Malo osungiramo zinthu ayenera kukhala ndi zida zochizira mwadzidzidzi zomwe zimatuluka ndi zinthu zoyenera zosungiramo zinthu.
Kupaka Zinthu:300kg/ng'oma
Kusunga: Sungani pamalo otsekedwa bwino, osapsa ndi kuwala, komanso chitetezeni ku chinyezi.
