Incazelo Yomkhiqizo:
I-Dibutyl phthalate (DBP) iyipulasitiki esetshenziswa kakhulu ye-PVC, engenza imikhiqizo ibe nokuthambile okuhle kodwa ukuqina okungekuhle. Ukuzinza, ukumelana nokuguquguquka, ukunamathela kanye nokumelana namanzi kungcono kunamanye amapulasitiki. I-Dibutyl phthalate ijwayele ukusetshenziswa njengesengezo kuma-adhesive nakuyinki wokuphrinta. Incibilika ezinhlobonhlobo zezincibilikisi eziphilayo, njengotshwala, i-ether kanye ne-benzene.I-DBP iphinde isetshenziswe njenge-ectoparasiticide.
I-Dibutyl phthalate (DBP) iyi-plasticiser enhle kakhulu, ingumkhiqizo omkhulu kanye nokusetshenziswa kwamapulasitiki ekilasini, inhloso ejwayelekile. Inoncibilika kahle ezinhlotsheni eziningi zama-resin futhi isetshenziswa njenge-plasticiser eyinhloko enombala okhanyayo, ubuthi obuphansi, izakhiwo ezinhle zikagesi, ukuguquguquka okuphansi, iphunga eliphansi kanye nokumelana nokushisa okuphansi.
Isicelo somkhiqizo:
1.Lo mkhiqizo uyi-plasticiser, awunabuthi.
I-2.Isetshenziswa kakhulu njenge-PVC plasticiser, engenza imikhiqizo ibe nokuguquguquka okuhle. Ngenxa yokushibhile kwayo kanye nokucutshungulwa kahle kwayo, isetshenziswa kabanzi eShayina, icishe ilingane ne-DOP. Kodwa-ke, ukuguquguquka kwayo kanye nokukhipha amanzi kukhulu, ngakho-ke ukuqina kwemikhiqizo kumpofu, futhi ukusetshenziswa kwayo kufanele kuvinjelwe kancane kancane.
3.Lo mkhiqizo uyi-plasticiser enhle kakhulu ye-nitrocellulose, enekhono eliqinile le-gelation. Isetshenziswa ku-nitrocellulose enamathela, inomphumela omuhle kakhulu wokuthambisa, ukuzinza nokunamathela. Ingasetshenziswa futhi njenge-polyvinyl acetate, i-alkyd resin, i-ethyl cellulose, irabha yemvelo neyokwenziwa, kanye nengilazi ye-organic kanye ne-plasticiser.
