Kugwiritsa ntchito mankhwala
Izi ntchito polycarbonate utomoni, tert-butyl phenolic utomoni, epoxy utomoni kusinthidwa, xylene utomoni kusinthidwa, polyvinyl kolorayidi stabilizer, komanso ntchito ngati ultraviolet absorbent, mankhwala, mphira, utoto ndi ena odana ndi odana ndi wothandizila, mafuta mafuta antioxidant, dispersant. , lubricant, detergent, accelerant and styrene stabilizer, dye ndi penti zowonjezera ndi zothamangitsira tizilombo ta mafakitale.
Njira yopangira
Alkylation ya phenol ndi isobutene.
Makhalidwe a thupi ndi mankhwala
Mu muyezo boma, ndi woyera flake crystal, insoluble m'madzi, pang'ono sungunuka mu alkali, sungunuka Mowa, komanso sungunuka mu methanol, acetone, benzene, carbon tetrachloride, ndipo akhoza hydrogenated.Ili ndi fungo la phenol pang'ono komanso poizoni, ndipo kachulukidwe kake (114 ℃, molt state) ndi 0.908.Malo otentha 239.8oC;Kuwala kwa 97oC;Malo oyatsira ndi pafupifupi 355oC;Viscosity (cp100oC) 3.00.
Kusungirako ndi Mayendedwe
Paulendo, pewani dzuwa ndi mvula.Zida zoyendera ziyenera kukhala zoyera komanso zouma.Ayenera kusungidwa m'nyumba zosungiramo zinthu zomwe zimakhala ndi kutentha koyenera ndikupewa kuwala ndi kuuma.
Poizoni ndi Chitetezo
Mankhwalawa ndi a poizoni wa mankhwala.Ili ndi zotsatira zoyipa za maso, khungu ndi mucous nembanemba.Kukhudzana ndi khungu kungayambitse dermatitis ndi kuwotcha ngozi.Kukoka mpweya, kukhudza mphuno, maso kapena kumeza kuyenera kutumizidwa kuchipatala kuti akalandire chithandizo.Mankhwalawa ndi owopsa ndipo amatha kuwotchedwa pamoto.Kuwola kwa kutentha kumatulutsa mpweya wapoizoni;Ili ndi fungo lapadera lokwiyitsa.Mukamagwira ntchito, muyenera kuvala zida zodzitchinjiriza, magolovesi a mphira ndi zinthu zina zoteteza anthu ogwira ntchito, ndikukhala kutali ndi moto wotseguka, samalani kuti mupewe poizoni.
Zolemba Packing
Wokhala ndi filimu ya polypropylene, yokutidwa ndi thumba la pepala losagwira kuwala, kulemera kwa ukonde 25Kg / thumba.
Kugwiritsa ntchito
Amagwiritsidwa ntchito popanga mafuta osungunuka a phenolic resins, ma stabilizer opepuka ndi zonunkhira.
Chilengedwe
Chogulitsachi ndi choyera kapena choyera cholimba kutentha kutentha.Ndi yoyaka koma yosapsa.Lili ndi fungo lapadera la alkyl phenol.Amasungunuka mu mowa, esters, alkanes, ma hydrocarbon onunkhira ndi zosungunulira zina organic, monga ethanol, acetone, butyl acetate, petulo, toluene, sungunuka mu njira yamphamvu ya alkali, sungunuka pang'ono m'madzi.Izi mankhwala ali ndi makhalidwe wamba phenolic zinthu, pokhudzana ndi kuwala, kutentha, kukhudzana ndi mpweya, mtundu pang`onopang`ono kwambiri.
