I-Paste Yomthwalo Ophuthumayo PU - Izinqubo Zokunquma Umbala Ophuthumayo, Ezinconywa

Umvuzo omkhulu wobukhanya bezinkomba zocingo oluhlu lwepaste ye-fluorescent pu kuyakuhlukanisa kusiko esihle sezinkomba, ekunikeza isiphazamiso esingaholakali esikhuluma izinhloso ezenziwa ngokwezimali ezinezimo eziphambene njengomlando. Lokhu okukhulu kwabukhanya kukhishwa ngumthwalo oqondile wezinkomba ze-fluorescent ozungezileyo owasetshenziswe kulwazi lwe-paste, owadinga ubukhohlwa obungavamile balesithashe (ultraviolet) bese bewubuyisela njengobukhohlwa obubonakala, ukudala isibonelo esikhulu sobukhanya obonakala sikhanya noma kube sele kugcwele. I-paste ye-fluorescent pu color iyafika kule bukhanya ngokuthuthukile ngokuthatha izinkamba nezinkomba ze-fluorescent ezitholwe ngokucophelela, ezakhiwe ngendlela eyiqinisekisa ukuthi zifanele ne-chemistry yepolyurethane. Ngaphandle kwezinkomba ezijwayelekile zezinhlelo zangaphandle noma angaphakathi, ezingahlala zidinga futhi zibuyisela ubukhohlwa, izinkomba ze-fluorescent kule paste ziyasebenzisa ngokushesha ubukhohlwa be-ultraviolet ukuthi kube yiligheli ebonakalayo, ukudala izicongo ezibonakala ngempela ngaphezu kokwenzekayo ngokwezimali ngezinkomba ezigcwele. Lokhu kwenza izinhloso ezincintshelwe ngu-paste ye-fluorescent pu zibe zibonakala kakhulu emoyeni phakade, emva kwegcwele, kanye ngaphansi kwebhubane lokugcwalisa. Izimpendulo zempilo zaleso bukhanya obungcono zihlala zihlala kuzinye izimo eziphathelene nokuphepha kwezimali apho ukubonakala kungaba yinto yokuphila nokufa. Abasebenzi basekuthulwa baphatha izixhobo ezincintshelwe ngu-paste ye-fluorescent pu ukuze babe bonakala emazingeni amhlophe, futhi abasebenzi basezindawo zokwenza zombuso baphatha izixhobo zokuphepha eziyizihlanguzi ukuze bathintathe imisholo yezindawo zokusebenza. Umphakathi wemoto uthola le mpendulo yobukhanya kumashine echashini amaciko ephepha nokuphinda kwezixhobo zokuphepha ezingafuna ukuthatha isikhathi sokuthatha isikhathi sendiza. Abayenza izixhobo zokuthanda nokuthenga zithola ukubonakala okuphucake ukuze kwenze izinhloso ezingenhanced ukuphepha kumsebenzi waphandle, ikakhulukazi emanzini apho izicongo ezijwayelekile azikwazi ukunika ukubonakala okufanele. Ubude baleso bukhanya kuyinto enye engcono yokuthi i-paste ye-fluorescent pu inikeza. Izongeza ezinzululwayo zokuphila kulesi sizathu zihlinzeka izinkomba ze-fluorescent ukuthi kungaphuliwe, ukuthi izicongo zilindele isilinganiso sakho kuwo wonke umlando wazo. Lokhu kusho ukuthi izixhobo zokuphepha, izihlabelo, nezinhloso zokuthenga zilindele izici zakho zokubona kakhulu noma ngemuva kexesha elide lokutholwa kubukhohlwa, kumzila, kanye nobuchwepheshe.

Izikhathi ezizimele ekunqamuleni kwesiphequluli esibonakalayo se-fluorescent pu color paste sibophezela izinyathelo zokwakha ngokunika ukusebenza kakhulu ngendlela engahambelani nazo, njalo bekugcinwa ubungakanani obuphumelelayo phakathi kwezinhlobo ezahlukene zamathuba e-polyurethane. Leli fomu alikho izinkinga ezihlukene zokwenza okutholakala ngezinkuni zocingo, kufana nokudonsa, ukwahluleka kwehlulekile, nezinkinga zokulinganisa okungaba yindlela yokulahlekelwa kwebhola nezimali zendlu yesimiso. Indlela yamanzi ka-fluorescent pu color paste iyakha ukulinganisa ngokucacile kuzinzile zokuphumula nezokunquma, ihlinzekela ukunqumiselwa okucacile kwezimbala okunika iziphumo ezifanayo phakathi kwezinhlobo. Abasebenzi basebenzisa amathuba ababili bafuna ukususa izinyathelo zokwakha njengoba le fomu ifakiwa ngendlela elungile kumathuba wokwenza amathuba e-polyurethane esikhona ngaphandle kokudinga izinyathelo ezithile zokuphatha noma iziqiniseko eziningi zokuphepha okutholakala ngeziphequluli ezindonsayo. Izici ezihle zokubamba kwamanzi ka-fluorescent pu color paste zihlenza ukwahluleka ngokushesha nokugcina kabonakalayo phakathi kwezinhlobo ze-polyurethane, zilungiselela izindawo ezibhothele nezihlaza okutholakala kakhulu ngezincwadi ezingahlulanga ngendlela efanele. Lokhu kuholela kusizo oluphumelelayo lwesurfactant esifakwe kumatrix we-paste, okususa ukuguquguquka kweyinsima futhi kuthuthukise ukuxhumana okugcina phakathi kwezibonakaliso nezinhlobo ze-polyurethane. Abasebenzi besiseko bafisela umbono othandekayo owaneliswa nguformat ye-paste, bavulela ukulungiselela kwesibonakaliso ngexesha elishaya lokuqhubeka kwezinyathelo ukuze bafinyelele izidingo zokulungiselela kwesibonakaliso. Isilinganiso se-ubungakanani be-fluorescent pu color paste sifaka ezintwendini zombili, i-aromatic ne-aliphatic polyurethane systems, sibonelela abakhethi ngobunikazi obuphumelelayo xa bavela izinhlobo ezintsha noma babuyekeza izinhlobo esikhona. Lokhu kubangela ukuthi akudingeki ukuba kube nenombolo eyinhlobo yezibonakaliso, kuyakholisekisa ukuthenga futhi kususa izidingo zokugcina, njalo bekugcinwa isebenza esifanayo phakathi kwezinhlobo ezahlukene zamathuba e-polyurethane. Le fomu yepaste ibonisa ubunzima obuhle kuzinhlobo zombili, i-one-component ne-two-component polyurethane systems, ibeke isibonakaliso esicacile ngokugcina kwezinyathelo ezide zokusebenza ngaphandle kokuhlukunyuka noma ukwahlulwa. Izidingo zokubonga kakhulu zibonakala ngokushesha ngokubona isibonakaliso esifanayo esitholakele ku-fluorescent pu color paste, kususa ukwahluka phakathi kwezinhlobo zokwakha futhi kususa izilinganiso zokulahlekwa. Ifomati ye-paste iyakha ukulungiselela okucacile kwesibonakaliso usebenzisa uhlelo lwespectrophotometric, lukhokelela izinqumo ezihle zokuphatha izibonakaliso okuhlinzeka izinhlobonhlobonyane zokwakha. Lokhu kusiza kwayo kusidlandla ngokushesha emsindweni wokwakha, kususa ukudotiwa kwezinto, kanye nokuthembeka kwegazi ngokugcina isimo esifanayo sobuchwepheshe.

Ukukhazimula kwezinkomba zomusa eziphucansi kwesithuthi sokumapula kuqukethe ukugcina komusa nokusebenza okudlulisayo phakathi kwemiphakathi engcono, kepha kuyisikhashana esifanele endaweni apho umusa wokubaluleka kakhulu ekusetyenziselweni komsebenzi womsebenzi nekuqinisekisa isimo. Lokhu kukhazimula kusuka emthwethweni wempilo yokustabiliza izimpawu ezinezinhla ngaphandle kokuchithwa kwezinkomba zomusa ngokulahlekwa ngu-radiation ye-ultraviolet, izindlela zempilo, ukuqashwa kwezinkinga, nokuqhamuka kwegandlayo okuhlala kuhlala kufezekile kuzindlela zehluko. Isithuthi sakumapula sokumapula sokumapula se-fluorescent pu siqukethe izinto eziyisisekelo ezinezinhla zomusa zomusa ezingeneyo, ezingavimba iziphazamiso ze-photochemical ezenza umusa wokuhlala wokuhlolwa kwizimpawu ezijwayelekile. Ukuhlolwa kwebhinesi kubonisa ukugcina kwezinhla ezinhle emva kwemizuzu engu-1000 yokuhlola imoto, ekulinganisa ngozinsuku eziningi zokuphatha kwemoto emaqathini amabi. Lokhu kukhazimula kakhulu kusivikela izixhobo, izihlabela, nezinto ezasekhaya zibuye ziqiniseke ukuthi zizungeze izimo zokubona kubo konke isikhathi sezinsuku zabo, kube yinkinga yokuguqula nokuthintela okuthintela ngezihlabela ezindala. Ukukhazimula kwesithuthi sokumapula sokumapula sokumapula sokumapula sokumapula kuvikela ukuphatha kwingozi enezindleko efunekayo ekusungulweni kwe-polyurethane ngaphandle kokuchithwa komusa noma izici ze-fluorescence. Lokhu kukhazimula kwezinkalo kufaka phakathi izimo zokuphatha apho izimpawu ezigcinwe ziya kufezekela izigaba zempilo, izigaba ezinemfutha, noma ukubonakala ngqo kwezinkanyezi ezingayohlala kuhlanjulula izimpawu ezijwayelekile. Izici ze-chemical resistance zivikela umusa ukushiswa, ukuhamba, noma ukuxhumana nozinye izinto ezijwayelekile kusithuthi se-polyurethane, ziqinisekisa ubunjani bomusa bokuphatha nokuvikela ukuchithwa kwezinye izinto noma izahluko. Ukuhlolwa kwezimali kubonisa ukuthi isithuthi sokumapula sokumapula sokumapula sokumapula sokumapula sinquma isimo sobuso xa kusenzelwa umlilo, inkanyezi yeshabhu, izinkinga zedjondjomane, nezobomi eziyisisekelo eziyahlala kuzenzelwa kumasebe nezimali. Lokhu kukhazimula kwezinkinga kusivikela izimpawu zomusa zisebenze ngokwengeziwe emanzini, emasimini, kanye namathuba aphakathi apho izimpawu ezijwayelekile zingasindile. Ukukhazimula kwegandlayo kwe-matrix ezigcinwe ngaphandle kwesithuthi sokumapula sokumapula sokumapula sokumapula sokumapula sibonisa ukukhazimula okuningi kwe-abrasion, impact, ne-flexural fatigue ngaphandle kokuhlala nomusa noma ukuchithwa. Lokhu kukhazimula kwegandlayo kwenza izimpawu zomusa zibe yisikhashana esifanele endaweni ephathelene kakhulu njengoko: ukulahla, izixhobo zokuvikela, nezixhobo zomshini, ezingafuna ukubona nokubona kubo konke isikhathi ngaphandle kokuphazanyiswa kwegandlayo. Ukusebenza okunembile kohlelo lwesithuthi sokumapula sokumapula sokumapula sokumapula lukhazimula inani elikhulu kubasebenzisi ngokuphindekayo kwezinsuku zomsebenzi, ukuncipha kwezidingo zokuphatha, nokusebenza okuphathelene kwezimali okuvikela izidingo zokulungiswa kanye nokuphatha kwezinkinga.
