Ukusetshenziswa
I-Pentaerythritol isetshenziswa kabanzi embonini yokumboza ukukhiqizwa kwama-alkyd resins.Lawa ma-resin ayingxenye ebalulekile yezingubo eziningi, ezinikeza ukuqina, ukunamathela kanye nokumelana nokugqwala.Ngaphezu kwalokho, i-pentaerythritol iphinde isetshenziswe kabanzi ekuhlanganisweni kwezithako ezithuthukisiwe ukuze inikeze ukusebenza okuphezulu nokuvikelwa okuhlala isikhathi eside kwemishini nezimoto.
Ngaphezu kwalokho, i-pentaerythritol iyisithako esibalulekile ekukhiqizeni ama-plasticizer nama-surfactants.Ama-Plasticizers athuthukisa ukuguquguquka nokuqina kwamapulasitiki, awenze abe yingxenye ebalulekile yezinhlelo zokusebenza ezahlukahlukene.Ngakolunye uhlangothi, izakhiwo ze-emulsifying kanye nezigwebu zama-surfactants zibalulekile futhi zisetshenziswa ezimbonini ezinjengokunakekelwa komuntu siqu, ukuhlanza kanye nezolimo.
Ngaphandle kwendima yayo ekusetshenzisweni okuhlukahlukene kwezimboni, i-pentaerythritol iphinde isetshenziswe ekuhlanganiseni izidakamizwa neziqhumane.Izakhiwo zayo zamakhemikhali eziyingqayizivele ziyenza ibe isithako esifanelekile ekwenziweni kwemithi, okusiza ekwandiseni ukusebenza kahle nokuzinza kwezinqubo ezithile.Ukwengeza, izakhiwo ezivuthayo ze-pentaerythritol ziyenza ibe isithako esibalulekile ekwenziweni kweziqhumane, okwandisa ukuzinza namandla alezi zinto.
Sekukonke, i-pentaerythritol iyinhlanganisela ebaluleke kakhulu ye-organic ehlinzeka ngezicelo ezimbalwa ezimbonini ezahlukahlukene.Ukuguquguquka kwayo kanye namakhemikhali ayingqayizivele ayenza ibe isithako esithandwayo ekwakhiweni kwama-alkyd resins, izinto zokugcoba ezithuthukisiwe, ama-plasticizers, ama-surfactants, imithi kanye neziqhumane.Ngefomu layo le-crystalline powder elimhlophe, lifakwa kalula ezinkambisweni ezihlukahlukene, linikeza ukusebenza okuhle kakhulu nokuthembeka.Themba i-pentaerythritol ukuze ikhuphule imikhiqizo yakho futhi ithuthukise ukusebenza kwayo.
