Ukusetyenziswa
I-oxide ye-2,4,6-Trimethylbenzoyldiphenylphosphine isIsetyenziswa kakhulu kwii-inki zokuprinta isikrini, ii-inki zokuprinta i-lithographic, ii-inki zokuprinta i-flexographic, kunye neengubo zomthi. I-TPO inokunyangeka ngokupheleleyo kwiindawo ezimhlophe neziphezulu ze-titanium dioxide pigment. Isetyenziswa kakhulu kwiingubo ezahlukeneyo, ngenxa yokusebenza kwayo okuhle kokufunxa, ifanelekile ngakumbi kwi-inki yokuprinta isikrini, ukuprinta okuthe tyaba, i-inki yokuprinta i-flexographic, kunye neengubo zomthi. Ingubo ayityheli, isiphumo se-post polymerization siphantsi, kwaye akukho ntsalela. Ingasetyenziselwa neengubo ezibonakalayo, ngakumbi ezifanelekileyo kwiimveliso ezineemfuno zevumba eliphantsi. Xa isetyenziswa yodwa kwii-polyester ezingagcwaliyo ezine-styrene, inokusebenza okuphezulu kokuqalisa. Kwiinkqubo ze-acrylic ester, ngakumbi iinkqubo ezinemibala, zihlala zifuna ukusetyenziswa kunye nee-amines okanye ii-acrylamides, kwaye zihlanganiswe nezinye ii-photoinitiators ukuze kufezekiswe ukuphiliswa ngokupheleleyo kwenkqubo. Zifanelekile ngokukodwa ukuphiliswa kokutyheli okuphantsi, iinkqubo ezimhlophe, kunye neengqimba zefilimu ezityebileyo. Ukudibanisa i-photoinitiator TPO kunye ne-MOB240 okanye i-CBP393 kunokuphucula ukusebenza kokuphiliswa. Yeyona nto ingcono kakhulu yokunyibilikisa izityalo ze-petroleum aromatic hydrocarbon kwaye ikwasetyenziswa njenge-formylation reagent kwicandelo leekhemikhali ezintle.
Yeyona nto ingcono kakhulu yokunyibilikisa i-hydrocarbon kwizityalo ze-petroleum aromatic hydrocarbon; Isisombululo esixutyiweyo se-N-formylmorpholine kunye ne-morpholine (1:1) sisinyibilikisi sokunyibilikisa iyunithi ye-methyl ethyl ketone. Ikwasetyenziswa njenge-formylation reagent kwicandelo leekhemikhali ezintle. Isetyenziswa kakhulu kwi-inki yokuprinta isikrini, i-inki yokuprinta ye-planographic, i-inki yokuprinta ye-flexographic, i-wood coatings, i-inki yokuprinta, i-inki yokunamathisela i-UV, i-inki yokuprinta, i-UV curing adhesives, i-optical fiber coating, njl.
Ukupakishwa kunye nokuthunyelwa
20KG/Ibhokisi okanye ngokweemfuno zabathengi.
Gcina kwaye ugcine
Ixesha lokuphelelwa: Iinyanga ezingama-24 ukususela kumhla wokwenziwa kwayo kwiphakheji yokuqala engavulwanga igcinwe kwindawo epholileyo neyomileyo kude nelanga elithe ngqo, amanzi.
Indawo yokugcina umoya, Ukomisa kubushushu obuphantsi, Yahlulwe kwii-oxidants, ii-asidi.
