Fluorescent mhlophe agentuye wahlala edlala indima ye "monosodium glutamate" kwiprosesa yeplastiki.Ukongezwa kwamawaka alishumi kungenza mhlophe kwaye kukhanye iimveliso zeplastiki kunye nokuphucula ukubonakala kweeplastiki.
Kukho iindlela ezininzi zokongeza ii-agent ezimhlophe, kodwa iindlela zabo zokusetyenziswa zihlulwe kakhulu zibe ziindidi ezintathu: umhlophe owomileyo, umhlophe omanzi kunye ne-masterbatch whitening.
Ukomisa mhlophe
Iplastiki eyomileyo emhlophe kukongeza umlinganiselo othile we-fluorescent whitening agent umgubo owomileyo ngokuthe ngqo kwi-substrate yeplastiki ngaphambi kokubunjwa, xuba kunye ne-substrate yeplastiki kuqala, kwaye ukhuphe umxube xa i-extruder ifikelela kubushushu obunyibilikayo beplastiki.Nyibilika kwisikrufu ukwenza i-agent emhlophe yeplastiki isasazwe ngokulinganayo ekunyibilikeni, kwaye ekugqibeleni uphumeze igranulation okanye ukubumba ucinezelo.
Inkqubo eyomileyo yokwenziwa mhlophe kweplastiki isetyenziswa ikakhulu kwinaliti yokubumba i-PVC eqinileyo, i-polyethylene, i-polypropylene, i-ABS kunye nezinye ii-resin thermoplastic.Ii-agent ezimhlophe ze-Fluorescent ezisetyenziswa kwi-ejenti ezimhlophe ezomileyo zinexabiso eliphantsi, kodwa zineengxaki zokusasazwa kothuli olukhulu kunye nongcoliseko lokusingqongileyo.
Ukwenziwa mhlophe kwesiganeko
Ukuze kuphuculwe isiphumo sokusasazeka kobumhlophe obumanzi, ngamanye amaxesha kuyimfuneko ukongeza inani elithile le-binder kwi-agent emhlophe yeplastiki, ukwenzela ukuba i-agent emhlophe yeplastiki ikwazi ukunamathela ngakumbi kumphezulu wezinto eziphathekayo, ukuze kuncitshiswe uthuli lwayo. ukubhabha kunye nongcoliseko.
I-plastic brightener ingaphinda ihlakazwe kwisisombululo sokuncedisa kwaye ifakwe kwiibhetshi ngendlela yokusabalalisa okuncedisayo.Ngokomzekelo, ingasetyenziselwa kwi-polyvinyl chloride ethambileyo (PVC), enokuthi yenziwe ibe yi-10% ye-phthalic acid.Emva kwesisombululo seplastiki ye-dioctyl ester, yongezwa kwiibhetshi.
Kwi-whitening emanzi, ii-agent emhlophe yeplastikiludaka olusasazwe kakuhle, olunobunzima bokuncangathi ngenxa yokuba isinyibilikisi sezinto eziphilayo esingaguquguqukiyo sixutywa kwiplastiki.IHony Chemical icebisa ngokubanzi le ndlela yokwenza mhlophe kwiPVC ethambileyo.
Masterbatch mhlophe
Okwangoku, ukusetyenziswa kwe "masterbatch" kwiiplastiki kuye kwaba yindlela ebalulekileyo yombala weplastiki.Xa usebenzisa umbala we-masterbatch, nje ukuba umbala we-masterbatch kunye ne-resin zixutywe ngokulinganayo ngokulinganayo, zingasetyenziselwa ngokuthe ngqo ukubumba iimveliso zeplastiki.
Inani elincinci lokuvuselela kufuneka lenziwe kuphela ngesandla.Kwimeko yexabiso elikhulu lokucubungula, ukwenzela ukuba kuqinisekiswe ukuchithwa kwe-masterbatch, ukuvuselela oomatshini kunokusetyenziswa.Emva kokuba umbala we-masterbatch uxutywe ngomatshini kunye neplastiki ye-resin, inokuthunyelwa kumatshini wokubumba inaliti kunye nesixhobo sokubumba kwangaphambili, kwaye umbala ulungiswe kwangaphambili ngexesha elifanayo.
Imiqathango yokusetyenziswa
Okokuqala, ubungakanani be-fluorescent whitening kufuneka ilawulwe kakuhle.Isixa se-arhente emhlophe esongeziweyo asilungile kangangoko kunokwenzeka.Isixa esigqithisileyo siya kwenza iplastiki ibe tyheli.Okwesibini, isikhanyiso kunye nezinto ezikrwada kufuneka zixutywe ngokulinganayo.
Nazi iindlela ezimbalwa zokusebenzisa izikhanyisi zeplastiki, kunye nezikhethekileyo okufuneka uzikhethe ngokwemeko yakho.Ukuba unayo nayiphi na imibuzo malunga nokusetyenziswa kweizikhanyisi zeplastiki, nceda uzive ukhululekile ukushiya umyalezo kwibhodi yemiyalezo.
