Triethylene Glycol Butyl Ether

Zosungunulira zogwira ntchito bwino komanso zosawononga chilengedwe, zomwe zimathandizira kukweza khalidwe m'mafakitale osiyanasiyana

Diethylene Glycol Butyl Ether (dzina la mankhwala: Diethylene Glycol Monobutyl Ether, dzina la Chingerezi: Diethylene Glycol Butyl Ether, chidule chake ndi DGBE) ndi chosungunulira chachilengedwe chogwira ntchito zambiri chomwe chili ndi mphamvu yosungunula bwino, kukhazikika bwino, komanso chitetezo cha chilengedwe. Ndi makhalidwe ake akuluakulu monga kutentha kwambiri, kusasinthasintha pang'ono, komanso kusungunuka m'madzi ndi mafuta, komanso ubwino wobiriwira wa poizoni wochepa komanso mpweya wochepa wa VOC, DGBE yakhala chowonjezera chachikulu m'magawo osiyanasiyana monga zokutira, inki, kuyeretsa mafakitale, zamagetsi, ndi mankhwala. Ikhoza kusintha molondola zosungunulira zachikhalidwe zomwe zimawononga kwambiri, kuthandiza mabizinesi kukwaniritsa zolinga zingapo za kukonza njira, kukonza magwiridwe antchito, komanso kukweza kutsatira malamulo.

Kuchita Bwino Kwambiri: Ubwino wamitundu yambiri, womwe umafotokoza muyezo watsopano wa magwiridwe antchito a zosungunulira

1. Kutentha kwambiri komanso kusasinthasintha kochepa, zomwe zimapangitsa kuti zomangamanga ndi kupanga zikhale zokhazikika

DGBE ili ndi kutentha kotentha kofika 230°C komanso kutentha kozizira kotsekedwa kwa 78°C, komwe kumasinthasintha pang'onopang'ono komanso mofanana. Muzochitika monga kupangidwa kwa kutentha kwambiri komanso kuphika kwa nthawi yayitali, imatha kusintha bwino liwiro la makinawo, kupewa zolakwika monga khungu la lalanje, mabowo ang'onoang'ono, ndi kuyera kwa filimu yophimba chifukwa cha kutentha kwachangu kwa zosungunulira. Nthawi yomweyo, kapangidwe ka kutentha kotentha kwambiri kamachepetsa kwambiri zoopsa zachitetezo panthawi yopanga ndi kusungira, zomwe zimagwirizana ndi zosowa zosiyanasiyana zazikulu zopangira mafakitale.

2. Mphamvu yosungunula yamagetsi yotakata, kusinthasintha kwamphamvu ku madzi ndi mafuta

Ili ndi mphamvu zabwino kwambiri zoyeretsera madzi (zonse zoyeretsera madzi ndi zoyeretsera mafuta), ndipo imatha kusungunula bwino zinthu zosiyanasiyana monga ma resin (acrylic resin, epoxy resin, alkyd resin, ndi zina zotero), nitrocellulose, mafuta, utoto, ndi mafuta amchere. Ikhoza kusakanikirana ndi madzi molingana ndi momwe imagwirira ntchito komanso imagwirizana bwino ndi zinthu zachilengedwe monga ethanol, acetone, ndi toluene. Ikhoza kusinthidwa mwachindunji popanda kusintha kwakukulu ku ma formula omwe alipo, zomwe zimachepetsa kwambiri mtengo wokonzanso formula yamakampani.

3. Zobiriwira, zotetezeka, komanso zomvera malamulo, mogwirizana ndi chitukuko cha kuteteza chilengedwe

Chopangidwa pogwiritsa ntchito njira yopangira zinthu zobiriwira, mankhwalawa ali ndi chiyero cha ≥99.5% komanso ali ndi zinthu zochepa kwambiri zodetsa. Ali ndi poizoni pang'ono, ndipo poizoni amachepetsedwa ndi oposa 75% poyerekeza ndi zosungunulira zachikhalidwe (monga ethylene glycol ethers) ndipo mpweya wa VOC umachepetsedwa ndi 90%. Chingathe kukwaniritsa mosavuta malamulo okhwima okhudza chilengedwe m'dziko ndi kunja monga GB, REACH, ndi TSCA, kuthandiza mabizinesi kudutsa zopinga zamalonda zobiriwira.

4. Kugwira ntchito bwino kwambiri polumikizirana, kukonza kukhazikika kwa dongosolo

Ili ndi ntchito zabwino zolumikizira ndi kukhazikika, zomwe zingathandize bwino kuyanjana kwa machitidwe osakanikirana, kupewa kugawikana kwa formula ndi mvula, ndikuwonjezera nthawi yosungira zinthu. Ikawonjezeredwa kuzinthu monga zotsukira ndi zokutira, imatha kusintha kwambiri mphamvu yochotsa kuipitsidwa, mtundu wa filimu, komanso kukana nyengo kwa dongosololi, ndikukwaniritsa bwino magwiridwe antchito azinthu.
