Ipulasitiki iyinhlanganisela ye-polymer eyenziwe nge-polyaddition noma i-polycondensation.Ukumelana kwayo nokuguquguquka kuphakathi, phakathi kwemicu nenjoloba.Yakhiwe ngama-synthetic resins kanye nezithasiselo ezinjengama-fillers, ama-plasticizers, ama-stabilizers, ama-lubricant, nama-pigments.ukwakheka.Ngenxa yezakhiwo zezinto zokwakha noma izinto zepulasitiki ezingagxotshwa ngokungafanele zibe yizimo ezihlukahlukene futhi ekugcineni zingagcina ukuma kungashintshiwe, imikhiqizo yepulasitiki ingabonakala yonke indawo ekuphileni kwethu kwansuku zonke.Ubuchwepheshe bokugaywa kabusha kwamapulasitiki nawo buvuthwe kakhulu.Oplastiki abaningi bayagaywa kabusha futhi baphinde basetshenziswe, futhi lawa mapulasitiki anemibala acutshungulwa ndawonye, ngokusatshalaliswa kwemibala engalingani, ukubukeka kabi, kanye nezinga eliphansi.Ngisho namapulasitiki amhlophe ahlanzekile asetshenziswa isikhathi esithile.Ukugaywa kabusha kungabangela ukuphuzi.Kulokhu, kuyadingeka ukwengeza i-ejenti emhlophe ye-fluorescent yepulasitiki ukuze ifane ne-hue yepulasitiki, ukwandisa ubumhlophe nokukhanya kwepulasitiki, futhi wenze ipulasitiki ibe nombala ongcono.
Yize inani le-ejenti emhlophe ye-fluorescent kumapulasitiki lincane kakhulu, libalulekile.Yiziphi izinto ezivame ukusetshenziswa ezimhlophe ze-fluorescent emkhakheni wepulasitiki?U-Xiaobian uncoma imikhiqizo yenkanyezi embalwa enezindleko eziphakeme zokusebenza kuwe namuhla.
Ipulasitikii-agent emhlophe ye-fluorescent OB, ukubukeka kwayo kuyimpushana ephuzi ekhanyayo, ifanele zonke izinhlobo zamapulasitiki, ukukhanya okuhle kokukhanya, ukumelana nesimo sezulu esihle, ukuvikelwa kwemvelo, futhi ingumkhiqizo we-agent emhlophe ye-fluorescent evunyelwe ukusetshenziswa kumabhande okufaka ukudla.I-Fluorescent whitening agent OB inokusebenza okuzinzile kakhulu kumapulasitiki, kodwa ubumhlophe bayo bungase bube kubi kakhulu.Uma unezidingo eziphakeme kakhulu kumhlophe, ngakho-ke lokhu akunconywa.
Ipulasitikii-agent emhlophe ye-fluorescent OB-1, lo mkhiqizo ungathathwa njengomkhiqizo wenkanyezi embonini yepulasitiki, ngentengo ethengekayo kanye nomphumela omuhle wokumhlophe.Ibuye ifanele imikhiqizo ehlukahlukene yepulasitiki, enenani elincane lokwengeza, ukumelana nokufuduka kanye nomphumela omuhle.Intengo yayo ishibhile uma kuqhathaniswa, futhi iwukukhetha kokuqala kwabakhiqizi abaningi bepulasitiki, kodwa emikhiqizweni ethile yepulasitiki, ukuzinza kwayo kubi futhi kulula ukufuduka.Ngakho-ke kusafanele ubuze isevisi yamakhasimende uma isebenzisa umkhiqizo wakho.
Ipulasitikii-agent emhlophe ye-fluorescent FP-127, lo mkhiqizo we-agent emhlophe ye-fluorescent kungathiwa uzalelwe ipulasitiki ye-PVC, ifanele zonke izinhlobo zemikhiqizo ye-PVC, inani elingeziwe lingu-2/10,000 kuya ku-5/10,000, futhi umphumela wokuba mhlophe uyabonakala., futhi imelana nokufuduka kumapulasitiki e-PVC.Noma ngabe uyimikhiqizo ye-PVC ethambile noma eqinile, ungakhetha i-agent emhlophe ye-fluorescent FP-127.
Ngaphezu kwalokho, amapulasitiki ezinto ezahlukene anamamodeli awo e-plastic fluorescent whitening agents.Uma ufuna ukwazi okwengeziwe, wamukelekile ukuthi ubuze futhi sizokuthinta ngokuningiliziwe.Sizoncoma uchwepheshe futhi oqondisiwei-optical brightenerumkhiqizo kuwe ngokomkhiqizo wakho.
