I-Trimethylolpropane/TMP Cas77-99-6

Incazelo emfushane:

I-Trimethylolpropane, eyaziwa nangokuthi i-TMP, iyinhlanganisela ye-organic ene-chemical formula C6H14O3.Kuyikristale emhlophe eqinile encibilika kakhulu emanzini futhi inokuqina okuhle kakhulu kwe-thermal namakhemikhali.I-TMP ikhiqizwa kakhulu yi-esterification ye-formaldehyde ne-intermediate compound trimethylolpropionaldehyde (TMPA).Le nhlanganisela eguquguqukayo inezici ezihlukile eziyenza ibaluleke kakhulu ezimbonini ezahlukahlukene.

Isicelo

- Izingubo zokunamathisela nezokunamathela: I-TMP iyisithako esibalulekile ekukhiqizeni izimbotshana ezisezingeni eliphezulu nezinamatheliso.Izakhiwo zayo ezinhle kakhulu zokwenza ifilimu, ukumelana nokuphuzi, nokuhambisana nezinhlobonhlobo zama-resin kuyenza ilungele lezi zinhlelo zokusebenza.

- Amagwebu e-polyurethane (PU): I-TMP iyisithako esibalulekile se-polyol ekukhiqizeni amagwebu e-PU yefenisha, izinto zangaphakathi zezimoto kanye nokufakwa kwe-insulation.Isiza ukunikeza ukuzinza kwegwebu eliphakeme, ukumelana nomlilo nokuqina.

- Izithambisi zokwenziwa: Ngenxa yokuqina kwayo kwamakhemikhali kanye nezakhiwo zokugcoba, i-TMP isetshenziswa kabanzi ekukhiqizeni izithambisi zokwenziwa, iqinisekisa ukusebenza kahle nempilo ende yemishini.

- Ama-Alkyd resins: I-TMP iyingxenye ebalulekile yezinhlayiya ze-alkyd zokwenziwa, ezisetshenziswa kabanzi ekukhiqizeni ama-coatings, ama-varnishes namapende.Ikhono layo lokuthuthukisa ukuqina, ukugcinwa kwe-gloss kanye nezindawo zokomisa kuyenza ibe isithako esibalulekile kulezi zinhlelo zokusebenza.

Ekuphetheni

Kafushane, i-trimethylolpropane (TMP) iyinhlanganisela eguquguqukayo nebalulekile edlala indima ebalulekile ezimbonini ezihlukahlukene ezifana nezingubo zokumboza, izinto zokunamathisela, amagwebu e-polyurethane, okothambisa kanye nama-alkyd resins.Izakhiwo zayo ezinhle kakhulu kanye nohlu olubanzi lwezinhlelo zokusebenza kwenza i-TMP ibe isithako esibalulekile emikhiqizweni eminingi.

Njengomphakeli onokwethenjelwa, siqinisekisa izinga eliphezulu kakhulu nokuvumelana kwe-Trimethylolpropane, okukwenza ukwazi ukuzuza imiphumela engcono kakhulu.Sicela uzizwe ukhululekile ukusithinta ukuze uthole ulwazi olwengeziwe noma ufake i-oda.Sibheke ngabomvu ukukuhlinzeka nge-TMP esezingeni eliphezulu futhi sihlangabezane nazo zonke izidingo zakho zamakhemikhali.
