Ukuphela kukusebenzisa iindlela ezithile zokunciphisa ukukhazimla komgangatho wokugquma.
1. umgaqo wokuphela
Idityaniswe nendlela yeglosi yomphezulu wefilimu kunye nezinto ezichaphazela iglosi, abantu bakholelwa ukuba ukuphela kukusebenzisa iindlela ezahlukeneyo ukutshabalalisa ukugudiseka kwefilimu, ukwandisa uburhabaxa obuncinci befilimu, kunye nokunciphisa ukubonakaliswa komphezulu wefilimu. ekukhanyeni.Inokwahlulwa ngokuphela komzimba kunye nokuphela kweekhemikhali.Umgaqo wokudibanisa ngokomzimba kukuba: yongeza i-agent yokudibanisa ukuze wenze ubuso bokutya bulingane kwinkqubo yokwenza ifilimu, ukwandisa ukusabalalisa ukukhanya kunye nokunciphisa ukubonakaliswa.Ukuphela kweekhemikhali kukufumana iglosi ephantsi ngokwazisa izinto ezithile ezifunxa ukukhanya okanye amaqela anje ngepolypropylene izinto ezihlonyelwe kwiingubo zeUV.
2. indlela yokuphela
I-arhente yokukhwelana, kwishishini lanamhlanje lokugquma i-UV, abantu ngokubanzi basebenzisa indlela yokongeza i-arhente yokukhwelana.Kukho ikakhulu ezi ndidi zilandelayo:
(1) Isepha yentsimbi
Isepha yesinyithi luhlobo lwe-agent yokulinganisa esetyenziswa rhoqo ngabantu bokuqala.Ubukhulu becala ezinye zentsimbi stearate, ezifana aluminiyam stearate, zinc stearate, calcium stearate, magnesium stearate njalo njalo.IAluminiyam stearate yeyona isetyenziswa kakhulu.Umgaqo wokuphela kwesepha yensimbi isekelwe ekungahambelani kwayo kunye namacandelo okugubungela.Inqunyanyiswe kwi-coating kunye namasuntswana amahle kakhulu, asasazwa kumphezulu wengubo xa ifilimu isenziwa, okubangela uburhabaxa obuncinci kumphezulu wengubo kunye nokunciphisa ukubonakaliswa kokukhanya kumphezulu wokugquma ukufezekisa. injongo yokuphela.
(2) Umthwebeba
I-Wax yi-arhente yokumata yangaphambili nesetyenziswa ngokubanzi, eye-organic suspension agent.Emva kokwakhiwa kokugquma, kunye ne-volatilization ye-solvent, i-wax kwifilimu yokugubungela ihlulwe kwaye inqunyanyiswe phezu kwefilimu yokugquma ngeekristale ezintle, zenza umgca wokukhanya okusasazayo kunye nokudlala indima yokucima.Njenge-agent matting, i-wax ilula ukuyisebenzisa, kwaye inokunika ifilimu imvakalelo emihle yesandla, ukuxhathisa amanzi, ukufuma kunye nokuxhathisa ubushushu, kunye nokuxhathisa amabala.Nangona kunjalo, emva kokuba uluhlu lwe-wax lwenziwe kumgangatho wefilimu, luya kuthintela kwakhona i-volatilization ye-solvent kunye nokungena kwe-oksijini, okuchaphazela ukomisa nokuphinda kufakwe ifilimu.Indlela yophuhliso kwixesha elizayo kukudibanisa i-polymer wax kunye ne-silica ukufumana eyona mpembelelo ibalaseleyo yokutshabalala.
(3) Izohlwayo zokusebenza
Ii-pigments ezibonakalayo, ezifana ne-diatomite, i-kaolin kunye ne-silica evuthayo, zizohlwayo ezisebenzayo ezisetyenziswa ngokukodwa njengeejenti zokulinganisa.Zizezi arhente zokukhwelana ezizaliswe yi-inorganic.Xa ifilimu yomile, amasuntswana awo amancinane enza umphezulu orhabaxa kwifilim ukuze anciphise ukukhanya okukhazimlayo aze abonakale ngathi yiMat.Impembelelo yokudibanisa yolu hlobo lwe-agent edibeneyo ithintelwe yimiba emininzi.Ukuthatha i-silica njengomzekelo, xa isetyenziswe njenge-agent agent, umphumo wayo wokulinganisa uya kuchaphazeleka kwizinto ezifana nomthamo we-pore, ubukhulu be-particle size kunye nokusabalalisa ubungakanani be-particle, ubukhulu befilimu eyomileyo kunye nokuba i-particle surface iphathwe.Iimvavanyo zibonisa ukuba ukusebenza kokuphela kwe-silica dioksidi kunye nomthamo omkhulu wepore, ukusabalalisa ubungakanani be-particle efanayo kunye nobukhulu be-particle kunye nobukhulu befilimu eyomileyo bungcono.
Ukongeza kwezi ntlobo zintathu zingasentla ze-agent esetyenziswa ngokuqhelekileyo, ezinye ioyile ezomileyo, ezifana ne-oyile ye-tung, zisenokusetyenziswa njengee-agent zokudibanisa kwiingubo ze-UV.Ikakhulu isebenzisa i-reactivity ephezulu ye-conjugated double bond ye-oyile ye-tung ukwenza i-bottom yefilimu ibe ne-oxidation eyahlukeneyo kunye nesantya sokudibanisa, ukwenzela ukuba umphezulu wefilimu ungalingani ukuphumeza umphumo.
