Ndi zoyera zamtundu wanji zomwe zimagwiritsidwa ntchito pazinthu zapulasitiki zotayidwa?

Mapulasitiki otayidwa ndi omwe timawatcha kuti zinthu zobwezerezedwanso, koma kunena pang'ono, magwiridwe antchito ndi mawonekedwe a zinyalala zamapulasitiki sizowoneka bwino ngati zida zatsopano ndi zida zowunikidwanso.Koma sizinthu zonse zapulasitiki zomwe zimafunikira magwiridwe antchito otere.

Malinga ndi zomwe zimafunikira pakupanga zinthu zapulasitiki, mapulasitiki otayidwa amatha kubwezeredwa ndi kugwiritsidwanso ntchito ndikusunga zinthu malinga ngati gawo limodzi la chinthu china likonzedwa kuti lipange zinthu zapulasitiki zofananira.

Mtengo wa zinyalala pulasitiki ndi wotsika mtengo kwambiri, ndipo khalidwe lake silidzakhala vuto.Komabe, chifukwa cha zinthu zosiyanasiyana zachilengedwe komanso zochita za anthu, mapulasitiki otayirira amakhala ndi imvi komanso achikasu kwambiri.Zopangidwa popanda chithandizo zimakhala ndi mawonekedwe achikasu chakuda komanso kukana kwanyengo, zomwe zimakhudza kwambiri malonda.

Pofuna kuthetsa mavuto azinthu zopangidwa ndi mapulasitiki a zinyalala, monga mtundu wachikasu wakuda ndi kukana kwa nyengo, opanga ambiri amasankha kuwonjezera zowonjezera zosiyanasiyana kuti apititse patsogolo khalidwe la mankhwala.

Mwa iwo, fluorescent whitening wothandizira ndi wofunikira kwambiri pakukonzanso zinyalala zamapulasitiki.Pambuyo powonjezera zinthu zapulasitiki zotayidwa ndi fluorescent whitening agent, kuyera ndi kuwala kwazinthuzo zasinthidwa kwambiri.Chifukwa chiyani choyezera choyera cha fulorosenti chokha chomwe chingapangitse pulasitiki yonyansa kuoneka yatsopano?Chifukwa fulorosenti whitening wothandizira wapadera fulorosenti ntchito amatha kuyamwa ultraviolet kuwala kwachilengedwe, ndiyeno kusandulika buluu-violet fluorescence ndi kutulutsa.Buluu ndi chikasu ndi mitundu yogwirizana.Pamene mafunde a kuwala opangidwa ndi awiriwa ali ofanana, kuwala kwa buluu ndi kuwala kwachikasu kusakanikirana kumatulutsa kuwala koyera, kotero kuti chowunikira choyera cha fulorosenti chikhoza kupanga mankhwala achikasu ndi oyera.Kuwala kwa Ultraviolet sikuwoneka ndi maso.Ikasinthidwa kukhala kuwala kwa buluu, imawonjezera kuchuluka kwa chiwonetsero cha chinthucho, motero imakhala ndi zotsatira zowala.

Chifukwa chake, popeza chowunikira choyera cha fulorosenti chikhoza kukhala ndi kuyera ndi kuwunikira, kodi mtundu uliwonse wa zoyera za fulorosenti ndizoyenera kugwiritsidwa ntchito m'mapulasitiki a zinyalala?Pali mitundu yambiri yowunikira fulorosenti.Kwa zinthu zomwe zili ndi zinthu zosiyanasiyana, mtundu wolondola wowunikira ungagwiritsidwe ntchito kuti chowunikira cha fulorosenti chikhale ndi zotsatira zake zabwino.

Palinso mitundu yambiri ya zoyera za fulorosenti zomwe zimagwiritsidwa ntchito popanga zinthu zapulasitiki zonyansa pamsika.Mapulasitiki a zinyalala wamba amagwiritsa ntchito fulorosenti whitening wothandizira OB-1, muzochitika zapadera 127 kapena fulorosenti whitening wothandizira OB adzagwiritsidwa ntchito.Ndiye kodi mitundu itatu ya mapulasitiki a zinyalala ndi yotani?1. Mtengo wa optical brightener OB-1 uli pafupi ndi anthu.Kuyera ndi kwabwino, ndipo kuwonjezera pang'ono kudzakhala ndi kuyera bwino.Choyipa chake ndikuti guluu lofewa liyenera kugwiritsidwa ntchito mosamala kwambiri.2. Chowunikira cha FP-127 chimapanga kuperewera kwa OB-1 mu PVC zofewa zapulasitiki, ndipo ndizoyenera kwambiri za PVC zofewa zapulasitiki.3. Ngati ndi pulasitiki yowonekera kapena pulasitiki yapadera, ganizirani kugwiritsa ntchito OB, chifukwa OB ili ndi mgwirizano wabwino, kukana kwa nyengo yabwino, ndi ntchito zambiri.
