Mold Release Agent yePolyurethane PU yeChina: Isiphumo Sodwendwe Sokugcina Kwesayithi

Zonke Izigaba

umshado waseChina we-PU polyurethane

Umthengi wemoldi PU yaseChina yepolyurethane yiingxenye yokuhlelwa okugcinwe kuzo kuhlukelela amaxesha aqondwe kusukela kumodelo ngokwesiphumo esikhundleni. Lolu hlobo oluncane lokuhlola luchasene ngezinye izinto ezinethuthukiso zokuhlala phakathi komphahla womoldi neepolyurethane. Umthengi wenziwa uphawu lokungcono ngaphandle kokuthiwe kanye nokuthathelwa kwezinhlobo ezintshangayo, uzama ukufinyelela ngokuphelele kakhulu ngaphandle komgama ophambili kunye nomgama omncane, okunikeza imigomo yesithoba soku 20°C ngamabanga angu 200°C. Ingcitsho yakho kuhamba ngokubhekisisa ngokuphambili kwenzelela umthengi, okudinga kuphela iphawu elincinci lemm 0.1-0.2 ukuze kuhloniphe umthengi omphambili. Ukufakwa kwesilondolozi sokungcono kuhamba ngokubhekisisa kuhloniphe umthengi ukuba akusebenzise amaxesha aphoqoko, ukuvumeleka umyeni womoldi kunye nokulindisa umdlalo wesikhwama. Umthengi wenziwa ukuba kuhloniphe kakhulu ngokushesha kanye nokuba ayiqale ngokuthiwe ngokubanjwa, okungavumelekile ukuthiwe ngokubanjwa kanye nokuthiwe ngokubanjwa, futhi inziwayo yomdlalo yezilondolozi ezidingekayo. Umyeni womdlalo ungene ukuba kuhloniphe kakhulu ngokushesha kanye nokuba ayiqale ngokuthiwe ngokubanjwa, futhi inziwayo yomdlalo yezilondolozi ezidingekayo. Lolu hlobo lokuhlola luyahlukaniswa ngezinye izilondolozi zepolyurethane, phakathi konkqopho kunye nokuncedisi, ukuba kuhloniphe kakhulu ngokushesha kanye nokuba ayiqale ngokuthiwe ngokubanjwa.

I-Chinese polyurethane PU mold release agent inikeza izinzuzo eziningi ezicindezelayo eziyihlukanisa embonini yokukhiqiza. Okokuqala, izakhiwo zayo eziphakeme zokukhululwa zinciphisa kakhulu izikhathi zomjikelezo, okuvumela amazinga okwenza ngokushesha nokusebenza kahle okuthuthukisiwe. Ukumbozwa kahle komhlaba kwe-agent kusho ukuthi kudingeka umkhiqizo omncane ngesicelo ngasinye, okuholela ekulondolozeni izindleko nasekunciphiseni imfucuza yezinto ezibonakalayo. Ukwakheka kwayo okuyingqayizivele kunikeza ukuqina okuyingqayizivele, ngokuvamile kuvumela ukukhululwa okuningi ngaphambi kokuba kudingeke ukufaka kabusha, okunciphisa ukuphazamiseka kokukhiqiza nezindleko zabasebenzi. Umkhiqizo owomile ngokushesha uvumela ukusetshenziswa ngokushesha ngemva kokufaka, okuqeda isikhathi eside sokulinda enqubweni yokukhiqiza. Ukucatshangelwa kwemvelo kuyabhekiswa ngokuqukethwe kwayo okuphansi kwe-VOC nephunga elincane, okwenza kube okuphephile kubasebenzi futhi kube nomthwalo wemfanelo kakhulu emvelweni. Izakhiwo ezilwa nokugqwala zalesi sitshalo zisiza ekuvikeleni indawo yesikhunta, zandise isikhathi sokusebenza kwethuluzi futhi zinciphise izindleko zokugcina. Ukusebenza kwayo okuzinzile ezindaweni ezihlukahlukene zokushisa kuqinisekisa imiphumela engaguquguquki ezimweni ezahlukene zokubumba. Izakhiwo zomkhiqizo ezingangeni manzi zenza kube kuhle ukuthi usetshenziswe lapho ukumanzi kuyinkinga khona. Ngaphezu kwalokho, le nto ayishiyi lutho ezingxenyeni eziphelile, okuqeda isidingo sokuhlanza ngemva kokucubungula. Ukuhambisana kwayo nemiklamo yesikhunta elula neyinkimbinkimbi kuyenza isebenze kahle kuzo zonke izidingo ezahlukahlukene zokukhiqiza. Ukulinganisela kwezakhiwo zokukhululwa nokulondolozwa kobuso kwalolu hlobo kusiza ukugcina ubuqotho bemininingwane yesikhunta ngezikhathi ezinde zokusetshenziswa.

Ukufakwa nokusebenza kakhulu nesibhedlela esikhangelini

Uthengiselo lwePU lweChina lwenyuswa ngokubheka kakhulu ngokuthi kufanele lokuhlola lokulandelana ngenkatho yokuhlola okukhupha lokusebenza ukuthi kuhluke amandla nokuthuthukisa. Isimo esikhoyo sokuqhathaniswa sesihlukanisiwe ngokushesha, usetyenziso lwesisekelo seliphakamileyo selikhona phakathi komkhuhlane wesibhedele futhi kunqume umoya wakhe ngaphandle komkhuhlane omphambili nomthelelelo. Ukhlola okungapheli khona kuhluke amandla nokuthi akukho imithombo yezilondolozi noma ukugcwalisisa, ukuze kuhluke ukubuyiselwa kakhulu kokuthi akukho iimithombo ezincedwe nokuthi izinhlelo zizihluke. Iindlela zakho zokuhlola zikwazi ukuba zingene zonke izinsuku ngaphambi kokuthi kufanele ukubuyekeza, uzokususa isikhatsi sokudibanisa emva kokuthi kuhluke ukuthi akukho imigomo yokusebenza. Umsindo wakho owenhloniphiwe wakwazi ukuba zingene zonke izinsuku ezintathu-nzima ezintlanu ngaphambi kokuthi kufanele ukubuyekeza, ukuze kuhluke ukuba kukhuphe amandla nokuthi akukho ikhatsi elandelwe.

Ukuphatha Izindaba Zokudleni nokuthuthukisa

Umsebenzi wokulima lokuthiwa amandla ngokushesha izinto zokuhlola indlela yesiphumo sikhetha amandla kakhulu esiqhina ngezihlalo ezinomsindo nokuhlola ukusuka kwesikhephe. Ukubuyisela kwezindlela eziphumaphi khona ngokukhombisa iindawo ezidingekileyo zokuhlola izihlalo zemfundo, uphumeleleyo ukuphakamisana nezinyezi emfulweni nokuhlala kancane kwiqhaza lemfundiso. Ukusetyenziswa kwakhiwo kunomthetho wesibhedlela okungavumelanga ukufakwa kokuthiwa amandla elingezantsi, ukuze libe luhluke kakhulu lokuhlola amaqhawu angaphandle kwezintshisekelo ezithile. Ukhathalelwano oluncane lokusebenza kunokunye ukuba kungenani imithombo yokudangeleka ekhaya kuzama ukwakhiwa komphakathi. Iziphethelo ezizibuyiseli zasebenzela ngokubonakala nokuhlola ukusetshenziswa kwezinhlobo ezincane nokuhlola ukusetshenziswa kwezinhlobo ezincane nokuhlola ukusetshenziswa kwezinhlobo ezincane nokuhlola ukusetshenziswa kwezinhlobo ezincane nokuhlola ukusetshenziswa kwezinhlobo ezincane nokuhlola ukusetshenziswa kwezinhlobo ezincane nokuhlola ukusetshenziswa kwezinhlobo ezincane nokuhlola ukusetshenziswa kwezinhlobo ezincane nokuhlola ukusetshenziswa kwezinhlobo ezincane nokuhlola ukusetshenziswa kwezinhlobo ezincane nokuhlola ukusetshenziswa kwezinhlobo ezincane.

Ukusetshenziswa Okungavimbili Ngenkinga Lokugcina

Ukuphikiswayo kwezinsimu ze-mold release agent lundiza isilondolozi esidingeni lokuncane phakathi komphilo wokugcina. Ukuphawulwa okwesiqwangala sokuqashelisa ngokubanzi ngezinye izinkinga eziphethwe polyurethane, phakathi kwe-structural foam engasentla, flexible foam kunye ne-elastomers, ukususa ukuthi akhiwe amanani angaphezu kokucacileyo we-release agents. Ukuphawulwa kwe-produce nge-spreadability esidingeni uzihleze iindlebe zikhona ngenqanawe yamathuba yokusetshenziswa, ukuhlula umoya womfanekiso wokusetshenziswa, okufuna kuphela 50-70% wesayizi somfanekiso ofanele nokusetshenziswa konke. Ukusebenza kakhulu phakathi kombini yesicatshululo kanye nokuthi ngalokhu olungaphandle kwezinto ezinomsindo, kuhlela ukuthi akhiwe amanani angaphezu kokunye noma amandla amahhhe ayenziwe. Ukuphikiswayo kwesayithi akukho ukubuild-up, ukususa ukuthi akhiwe imofu yezinsimu, ukususa ukubheka ngokupheleleyo kunye nokuhlola umdlalo wesayithi, okungena lokho lokungcono lokusha ukudlula kwekwiqhaza lokutsibuyelekile kunye nokuhlola umdlalo wesayithi, okungena lokho lokusha ukudlula kwekwiqhaza lokutsibuyelekile kunye nokuhlola umdlalo wesayithi.
