Ukunciphisa Ukunyakaza: Izindlela Zokugcina Okudala Kwezivakashi Zeemfazwana Ye-PU

Ukwenza izinhlanzi zepolyurethane iMIKHIQIZO kudinga ukulungiswa kwesayensi ekususweni ukuze kube yimali phakathi kwezikhungo nezinhloso ezimiselwe. Isimo sesizathu sePU foam release coatings sibangelwa ngqo kumsebenzi wokwakha, ubunzima bezinto, nokugcina kwezimali zokwakha. Ukuqonda izahluko ezifundamental ngothando lwesizathu nokunciphisa ukuthutha kusinika umsebenzi othile emva kwezikhathi ezide zokwakha ngemuva kokugcina ubunzima obuhle kusayensi sezinhlanzi.

Imisebenzi yasezindustri iyadinga izinqumo zokukhupha ezingcono kakhulu ukusebenza ngaphandle kokuthwala isimo esizungezileyo kumatyulwa wamakholwa. Izibhamu zesibhamu se-PU ephethwe ngendlela ethile sengqondo zisetyenziswa ukunciphisa ukuthwaleka kodwa kuzinikezela izici ezifanelekileyo zokwahlukaniswa. Lezi zibhamu ezithile kumele zilungiselele izici zokukhupha nezici ezincane zokudala umnyango, ukuqinisekisa izikhathi ezide phakathi kwemisebenzi yokucula amakholwa.

Imigwaqo yesayensi eyisisekelo iyadinga izisombululo ezingcono kakhulu ekulandelweni iindlela ezahlukene zokwakha ngelishwa kuzinikezela iziphumo ezifanelekileyo. Ukukhetha kwezibhamu ze-PU ephethwe ngendlela ethile kufuneka kubhekane nokulinganisa okuningi kwingcamango ye-foam, izinto zomgca, amatempeli athola kuyo, namaxesha we-cycles. Izinqumo zezimali ezinezimo ezihle zinika inkululeko enkulu kanye nokuncipha kwezidingo zokuhlengahlenga ngaphandle kokuba yinto efana naleyo.

Uhlelo Lwezidlavu Nezimo Zokusebenza

Izinqumo Ze-Silicone

Amakhemikhali akwazelayo okususwa kwe-PU anesilicone ahlola ukutholakala kwezinkinga nezokugcinwa kwezinkumbulo ngokuhlanza kwizimo ezahlukene. Lezi zinhlelo zenza izimpapama eziphezulu ezingaphansi ukuze zivikile ukuthunywa kwebhobho ngasempini ikakhulukazi ingcwalisa.

Tekinoloji za ukubeka izinkuni ebonisa isimo sezinkuni kanye nokuphila okusemva. Izikhombisa zokushintsha kwembala zibhala xa kudingeka ukubeka kabusha, ekuthintela konke okungcono futhi kungavikeli ukupheleka kusuku olukhulu. Amagunya akhethekile ayethulwa ngempilo ethembekile wokuthuthukisa izinto ngenkathi ikhona inkabi yasimiso.

Izinqubo Zokuhlola Nokulawula Ikhwalithi

Ukulungiswa Kwezinkabi Zokuthulaswa

Amathuluzi aphephile yokuhlola izinkabi zokuthulaswa ze-PU foam azilungiselela amapharamitha amaningi angokulungiswa kanye nokuthulaswa, ubomi bomgodi wokugcina, kanye nokuphila kwezinkabi. Amathuluzi esivivinywayo ekulungiseni kakhulu ayehlola izici ezifanayo zokulinganisa nokulinganisa okufanelekile phakathi kwezinhlobo ezahlukene zezinkabi. Izinhilo zokuhlola evela ku-laboratory zihlandla imizamo yezimali ukuze ziqinisekise inkabi yezinkabi.

Izindlela zokulinganisa ngokuxhumeleka zilinganisa izimo zokukhupha ngasimiso yezixhobo zokulinganisa indlela enamacala kanye nezibalo ezivalemileyo. Ulinganiso lwesilinganiso sesihlangothi sisebenzisa ukulinganisa kwizimo zokugcinwa kwamaphrofayela esigxina. Izilingano eziyekelwayo zicinga ubungakanani bokusebenza ngeminyaka emihlanu phakathi kwezimo ezahlukeneyo.

Izindlela Zokuhlola Ukulawula

Izindlela eziphucwayo zokunquma zihlanganisa izindawo zokulawula futhi zicinga impikiswano yawo kumsebenzi wamaphrofayela okukhupha we-PU. Ize nezindlela zokunquma kusona isiqaleko sokulinganisa umkhiqizo wamaphrofayela futhi zithole izinto ezingenakho. Ukhlwebuka ngokomjikelozo kubonisa izinguquko zesilinganiso nendlela yokulawula.

Izinhilo zokuhlaziywa kwegcinelelo kuyadinga ukuhlanganiswa kwezinhawu zamagugu nezinhilo zokuthembeka. Izinhilo zokuchazwa kwesithamo kuyamelela ukuthembeka kwezinhilo ngeminyaka yakhala. Ukubalwa okuphelele kwebumbane kumenza kube yimali ukuthuthukisa izinqumo ezihlola ukulungiswa nokulungiswa kwezinhilo zokucima.

Imibuzo Evame Ukubuzwa

Kutheni kufanele kube khona isikhathi esizayo sokugcina amagugu e-PUR yokuthembeka ngemuva kwenxa

Isikhathi sokugcina futhi amagugu e-PUR ayisethetha emva kwenxa siyaphila kumazinga amathathu njengehlo lo-magugu, uhlo lwamagugu, isimo sezulu, nendiza yenza. Izigaba ezibomvu eziphelele ze-silicone zangele izikhathi ezingu-50-200 ngaphambi kokuthi kudingekile ukugcinwa futhi, ngelixa izigaba ezivela ku-wax kudinga ukubuyekezwa ngasikhathi esingu-10-50. Ukuhlola kahle kwezikhathi zokuthembeka nokulinganiso kwezehlo kusiza ekubaleni isikhathi esifanelekile sokugcina futhi kulolu hlelo lokusebenza.

Yini eyenzela ukuthi kube khona ukuthi amagugu agcine amakhiqizi ngaphandle kokusebenzisa amagugu akhona akhona?

Ukudala kwezindlela kutholakala ngamathuba amaningi akwenzeka njengokuthi kugcinwe kakhulu, ukulungiswa okungaphethelene kwesandla, okulahlekile amaphutha wesibayi , noma izimpendulo ezingavumeleki. Izigaba zemvula ngaphandle kwemeko efakiwe kuzokhula umsindo wokulungiswa nokudala kwamabhodha. Izindlela zokugcina, izibonelo eziqashelwa kakhulu, nezibonelo zokulinganisa zikuphela izinkinga zonke phakathi kokugcinwa kwezindlela eziqinile.

Kungani ungahlanganisa izinhlobo ezihlukene zeziphumo PU foam release coatings noma uzilaye ukuze kube neminyaka engaphezulu

Akukholelwe ukuthi uhlanganise izinhlobo ezihlukene zeziphumo PU foam release coatings ngoba kungaba nokulingana okungalungile okungakwazi ukuqhiphisa umbono futhi kwenze izinkinga. Kodwa, abafana bethembeka abanye bavela nezinhlobonhlobo ezivumeleki ezibekwe ngokulandelana. Hlola izicelo zomlando noma zaziso, futhi uqaphele ukulingana kwazo kabefore ekunyanisana neziphumo ezahlukene zokulunga, ukuze uhlangane nomphumela ongcono futhi ungavikele izinkinga.

Kufuneka zenze njani iziqinisekiso zokuphepha xa usenza imisindo ye-PU foam release coatings emidini yezindiza

Iziqinisekiso zokuphepha zokusebenzisa imisindo ye-PU foam release coatings iyasebenza ukulungiswa kwentliziyo, izixhobo zobomi olufanelekileyo, nezibophelo zokusebenzisa. Ukulungiswa kwezulu kusenela ukuthatha imithwalo yesimo noma izinto ezihlukileyo ze-mist. Ukuphepha kwezimpofu nokubeka izigcobo ezingalunganga kuzo kuziphatha okuthintekayo. Izinqumo zokuphazamiseka kwesimame kuthinta izindlela zokuthiwa isimame xa kusebenziswa imisindo engaphaya kwegesi. Ukwando lujulile kusenela ukusebenzisa ngendlela efanelekileyo nokuphendula ngempatho ngemva kokwenzeka kweziphazamiso.
