Kuzo zonke iimveliso zeplastiki, ii-akhawunti ezimhlophe zenxalenye enkulu yeeplastiki, ezinjengeebhokisi ezimhlophe ezimhlophe,I-PVCimibhobho yokukhupha amanzi, iingxowa zokutya ezimhlophe njalo njalo.Kwinkqubo yokucubungula, abaninzi abavelisi bandisa ubumhlophe babo ngokongeza i-fluorescent whitening agents.Nangona kunjalo, abavelisi abaninzi baya kuhlangabezana nengxaki enjalo, eyongeza i-fluorescent whitening agents.Kutheni imveliso "yam" imhlophe Ngaba ihlala iphucula kancinci?
Namhlanje, uXiaobian uhlalutya isizathu sokuba ubumhlophe bungaphucukanga nangona i-agent emhlophe ye-fluorescent yongezwa kwiplastiki…
1. Ingaba uhlobo oluchanekileyo lwe-agent emhlophe ye-fluorescent ekhethiweyo?
Kukho iintlobo ezininzi zeemveliso zeplastiki, kwaye iimpawu zabo kunye neenkqubo zokuvelisa nazo zahlukile.Ngoko ke, iintlobo kunye neepropati ze-fluorescent whitening agents ezifunekayo ziyahluka.Umzekelo, iingxowa zokupakisha zeplastiki ezicacileyo esizibonileyo zinokuhanjiswa kokukhanya okungcono kunye neemfuno zokumelana nemozulu kwiiarhente ezimhlophe, ke kuyacetyiswa ukuba kusetyenziswe iarhente yokukhanyisa mhlophe. OB kwiimveliso zeplastiki ezicacileyo;kwiiplastiki zobunjineli, kuyacetyiswa ukuba usebenzise i-agent emhlophe ye-fluorescent OB.I-arhente emhlophe i-OB-1.
2. Umthamo wei-agent emhlophe ye-fluorescent
Nangona i-agent emhlophe ye-fluorescent ikhanya, ayisiyiyo into yokuba isixa esongeziweyo esongeziweyo, ngcono.Uphando lubonisa ukuba xa isixa se-agent emhlophe ye-fluorescent eyongeziweyo kwi-matrix yeplastiki nganye idlula ixabiso elithile, iya kwenza i-agglomeration, inciphise umphumo wobumhlophe, kwaye ibangele nokulahleka kweenwele.I-phenomenon ye-yellowing, kwiimeko ezinzima, iya kubonisa umbala we-ejenti emhlophe ngokwayo, okubangela ilahleko eninzi kuneenzuzo.
3. Impembelelo yee-pigments kwifomula yokucubungula iplastiki kwisiphumo sokwenza mhlophe
Umgaqo-nkqubo wesenzo se-fluorescent whitening agents kukuguqula ukukhanya kwe-ultraviolet ekukhanyeni okuluhlaza okubonakalayo okanye ukukhanya kwe-violet.Amacandelo anempembelelo enkulu kwi-fluorescent whitening agents zizinto ezinokuthatha ukukhanya kwe-ultraviolet, oko kukuthi i-pigments emhlophe kunye ne-ultraviolet stabilizers.Umzekelo: i-titanium dioxide kwii-pigments ezimhlophe inokufunxa amaza okukhanya angama-380nm ekukhanyeni kwe-ultraviolet, kwaye ukuba ikhona kwiimveliso zeplastiki, iya kunciphisa isiphumo sobumhlophe be-fluorescent whitening agents.Ukuba i-titanium dioxide isetyenziswe kunye ne-fluorescent whitening agent, kuyacetyiswa ukuba kusetyenziswe uhlobo lwe-anatase titanium dioxide kwaye kwandiswe ngokufanelekileyo umthamo we-agent emhlophe ekhanyayo.
Ngaba la manqaku angasentla ayisombulule ingxaki yakho xa usebenzisa izikhanyisi kwimveliso yeplastiki?Namhlanje, umhleli uya kwabelana ngezi meko zintathu zingasentla ezinokuthi zenzeke xa wongeza iiarhente ezimhlophe.Okwangoku, sineentlobo ezahlukeneyo zamalungiselelo okwenziwa mhlophe kwe-fluorescent yeemveliso zeplastiki ze-Subang, kwaye sibonelela ngeenkonzo zobugcisa kwiimfuno zakho zokwenziwa mhlophe.
Ngeminye imiba emhlophe yeplastiki, wamkelekile ukuba ufowunele i-Shandong Subang Fluorescent Technology yonxibelelwano.
