Ingcaciso yeMveliso:
I-Dibutyl phthalate (DBP) yeyona plastiser isetyenziswa ngokuqhelekileyo kwi-PVC, enokwenza ukuba iimveliso zibe nokuthamba okuhle kodwa ukuqina okuphantsi.Ukuzinza, ukumelana nokuguquguquka, ukubambelela kunye nokuxhathisa kwamanzi kungcono kunezinye iiplastiki.I-Dibutyl phthalate isetyenziswa ngokuqhelekileyo njenge-additive in adhesives kunye nee-inki zokuprinta.Iyanyibilika kwiintlobo ngeentlobo zezinyibilikisi eziphilayo, ezifana notywala, i-ether kunye ne-benzene.DBP ikwasetyenziswa njenge-ectoparasiticide.
I-Dibutyl phthalate (DBP) yi-plasticiser egqwesileyo, yeyona mveliso inkulu kunye nokusetyenziswa kweplastiki eklasini, yinjongo-jikelele.Inonyibiliko olulungileyo kwiintlobo ezininzi zeereyini kwaye isetyenziswa njengeplasitiki ephambili enombala okhanyayo, ubutyhefu obuphantsi, iipropathi ezilungileyo zombane, ukuguquguquka okuphantsi, ivumba eliphantsi kunye nokumelana nobushushu obuphantsi.
Isicelo seMveliso:
1.Le mveliso i-plasticiser, ayinayo ityhefu.
2.Isetyenziswa ikakhulu njengePVC plasticiser, enokwenza iimveliso zibe nokuguquguquka okuhle.Ngenxa yokungabizi kwayo kunye nokuqhubekeka kakuhle, isetyenziswa kakhulu eTshayina, iphantse ilingane neDOP.Nangona kunjalo, ukuguquguquka kwayo kunye nokutsalwa kwamanzi kukhulu, ngoko ke ukuqina kweemveliso kubi, kwaye ukusetyenziswa kwayo kufuneka kuthintelwe ngokuthe ngcembe.
3.Le mveliso yi-plasticiser egqwesileyo ye-nitrocellulose, enobuchule obunamandla be-gelation.Isetyenziswe kwi-nitrocellulose coating, inefuthe elihle kakhulu lokuthambisa, ukuzinza kunye nokunamathela.Isenokusetyenziswa njenge-polyvinyl acetate, i-alkyd resin, i-ethyl cellulose, irabha yendalo kunye neyokwenziwa, kunye neglasi ephilayo kunye neplastiki.
