Ukusetshenziswa
I-Pentaerythritol isetshenziswa kakhulu embonini yokuhlanganisa. Ingasetshenziswa ukukhiqiza izembozo ze-alkyd resin, ezingathuthukisa ubulukhuni, ukucwebezela kanye nokuqina kwefilimu yokuhlanganisa. Isetshenziswa futhi njengento eluhlaza yama-ester e-rosin adingekayo opende, ama-varnish kanye noyinki wokunyathelisa, futhi ingasetshenziswa ukwenza uwoyela wokomisa, izembozo ezishayo kanye nezinto zokugcoba zezindiza. Ngaphezu kwalokho, isetshenziswa nasekukhiqizweni kwemithi, izibulala-zinambuzane neminye imikhiqizo. I-molecule ye-pentaerythritol iqukethe amaqembu amane alinganayo e-hydroxymethyl futhi inezinga eliphezulu lokulingana. Ngakho-ke, ivame ukusetshenziswa njengento eluhlaza yokulungiselela amakhemikhali e-polyfunctional. I-nitrification yayo ingakhiqiza i-pentaerythritol tetranitrate, okuyi-explosive enamandla; i-esterification ingathola i-pentaerythritol triacrylate, esetshenziswa njengesembozo. Ingasetshenziswa futhi njenge-flame retardant yezinamathiseli. Uma ihlanganiswa ne-ammonium polyphosphate, kungatholakala i-intumescent flame retardant. Iphinde isetshenziswe njenge-ejenti yokuxhumanisa i-polyurethane ukuze inikeze amaketanga ahlanganisiwe ku-polyurethane.
Ukupakisha Nokuthumela
Ukupakisha: 25/kg,Izikhwama zepulasitiki ezilukiwe noma zephepha eliyi-kraft noma ngokwezidingo zamakhasimende.
Ukuthunyelwa: kungokwamakhemikhali avamile futhi kungalethwa ngesitimela, ulwandle kanye nomoya.
Gcina futhi ugcine
Isikhathi sokuphila: Izinyanga ezingama-24 kusukela ngosuku lokwenziwa kwento epakishweni lokuqala elingavulwanga, igcinwe endaweni epholile neyomile kude nokukhanya kwelanga okuqondile, amanzi.
Indawo yokugcina izinto enomoya, Ukomisa okuphansi kwezinga lokushisa, Ihlukaniswe nama-oxidants, ama-acid.
