Zonke Izigaba

umshado wokufakwa kwezilondolozi lesoft foam polyurethane

Isolwazi sokukhupha kwe-mold ye-polyurethane engcwele kuyisolution ephathelene ngokuthi ihlanze izinhlayiya zepolyurethane ukusuka emakhineni okwenza izimvume. Leli gama elibalulekile ekubeni yindlela yokuhlukana phakathi kwezinhlayiya ezihlanya nezinhlangothi zemvume, ukukhokha ukudluliswa futhi uqiniseke ukuthatha izinhlayiya ngendlela efanelekile. Solwazi sokukhupha kwe-mold ye-polyurethane sebenza ngokusebenzisa izinhloso ezihlelekile zezinhlangothi, ekhiqiza isifazane esincane sokulayisha okunciphisa ukugaya nokukhokha ukudluliswa kwezinhlayiya ezithembekile nemvume. Izinhlelo zakamuva ziqukethe izintambo ezihlelekile zezinhlelo ezingcono ezibonakala kakhulu kumgudu wonke wokwenza futhi uzilondoloze amandla emvume. Isolwazi sinezici ezihle eziyisisekelo njenge-stability yesilinganiso, ukungabibi kwezinkinga, nokulayishwa ngendlela efanele. Iziphawu zalo ziqukethe ixesha elincane lokusebenza, ukungenayo kwezinkinga, nokutholakala kahle ngezinhlangothi ezahlukene ezifana nale-aluminum, i-steel, nezinhlangothi ezimbili. Solwazi sokukhupha kwe-mold ye-polyurethane sinesici esihle sokunqamula, uqinisekisa ukulayishwa kuzinhlangothi zonke futhi kuzinhlangothi ezinkulu nezinhlangothi eziningi. Izindlela zokulayisha zihlala phakathi kwezomshini zokulayisha kanye nezindlela zokulayisha ngobhusha, zihlengeza izimo ezahlukene zokwakha kanye nezidingo zokusebenza. Amasipala abasebenzisa lolu tekinoloji aqhubekeka ekwakheni izimpilo, ukwenza izihlahla, izixhobo zokupaki, kanye nezimali zokubungaza. Ifomule yaleli solwazi ikhokha izici ezithintekayo zokwakha njengezinkinga zezinhlangothi, ukukhuphazeka okungafanelekile, nokudlalwa kwemvume, ngakho-ke kanciphisa ububi bokwakha kanye nokwehlukaniswa kwezinto. Izidingo ze-envoronment zathinta ukuthuthwa kwezinhlelo ezingcono ezinengci encane kanye nezinhlelo ezivela emanzini ezibonakala kakhulu futhi zihlale ziqinisekisa izidingo ezithintekayo zokulawula. Izinyathelo zokuhlela ububi bezici ziqinisekisa ukusebenza okufanele kuzingxenye zonke, zihlengeza izinyathelo zokwakha kanye nokuthola iziphumo ezifanele.

Ukusebenza Kokuqaqa Okungcono Nokulandelana

Isisekelo sokukhupha isithebe sangaphakathi se-polyurethane singaqinisekisa ukukhupha ngokusebenza kwamandla kakhulu ngenxa yobuchwepheshe bakhe obuqondile okwenza indawo ephansi kakhulu, eyodwa phakathi kwezithebe zangaphakathi nezimvavanyo. Lokhu kubalulekile ekunikelweni kokuthola izimvavanyo ngaphandle kweziphazamiso zezinto noma izinkinga zokudibana okuhlawula kakhulu emshinelweni. Ukusebenza kwesisekelo kusisodwa kungahlelekile ukuthi kunciphise izidingo zokulahleka kwezimali nokulinganiselwa kakhulu emshinelweni wokwenza izithuthi. Ubuchwepheshe bwayo buhlanganisa amagunya ahlelekile angcono ekunikezeni ukugcinwa kanye nokhula kwezinga elijwayelekile, okusisodwa kuthinta ngendlela efanayo izimvavanyo ezinhlelekile njengabezifazane, izindlela ezihlangothini, nezinye i-overhangs. Isisekelo sokukhupha isithebe sangaphakathi se-polyurethane sikhupha ngokushesha ngemva kukaqapha kwezimali, sinquma ukusebenza okusisodwa okuthintela umsebenzi ojwayelekile ngaphandle kokulinga kwezimali noma ukuthutha kwezindleko. Lokhu kusisodwa kuyadingeka kakhulu emshinelweni enzima apho izinkolo zomshinelwa azikwazi ukumelana nokucopheleka kwezimvavanyo noma ukubuyiselwa kwesisekelo sokukhupha. Ukuqina kwesisekelo kusisodwa kuhlala kuthinta ngokujwayelekile imigomo yenthalpi, kuvumela izimo ezahlukene zokushisa futhi kungaba nokulinganiselwa kwebhafomu noma izimo zokuphila ngaphandle kokulahleka kwezindleko. Amaqashi ebhizini anethembalelo ekukhupheni okufanelekile okunciphisa ukulahlekelwa komshinelwa nakho kujwayelekile kakhulu kakhulu kodwa kubona intonga yokuguquka kwebhafomu. Ukusebenza okumnandi kwasisekelo sokukhupha isithebe sangaphakathi se-polyurethane kusisodwa kukhona okunciphisa ukusheshwa kwezimali, ukulinganiselwa kwebhafomu, nakho kude kude kwezimali zomshinelwa. Ukuzimisela kwalo kusisodwa kuthinta izindleko zomshinelwa ngokunciphisa izinto ezingalwahlwayi futhi kunciphise izindleko zokucopheleka kwezimvavanyo.

Ukuphinda Ukuphawula Kwabhokisi Nekuhlonipha Kwesikhashana

Isivimba se-mold release agent sokuphazanyiswa kwe-polyurethane kusiza ekugcineni izimoto ngokukhanya, kube yizindlela zokunakekela ubude bezinkala kwaye kuthintele izindleko zokubuyisela. Isivimba esinamandla sokuphatha sikhupha ukuthwalwa kwegesi kususelwa kwizinto ezisebenzayo eziphazanyiswa okungasiphazanya ngesimo sezandla, uhlaza, nokuguqulwa komkhawulo wezimoto. Lokhu kukhupha kubaluleke kakhulu xa kusebenziswa nezibalo eziphazanyiswa ezinezigaba, i-blowing agents, nezigaba ezinye ezinobuchwepheshe ezingasendlela izandla ezingavikelekanga. Izici zokudala ifayela zalesi sivimba zakha isivimba esinamandla sokuphatha okuthintela ukucodwa nokuhlukahluka ngemva kokuphazanya kwingxaki, ekugcineni igunya lesimoto nesimo somkhawulo wazo emva kokusebenza kude. Lesi sivimba sisetshenzisa izinhlelo zokuphatha uhlaza okunikeza ukuphatha okudingekile kumathuba ebomini enza kumthwalo womlilo nezigaba ezinobuchwepheshe kumazinga okwasebenzwa khona. Ukubaqhathaniswa kwalo nokutholakala kwamathuba athile njenge-aluminum, isteel, namathuba amaningi akhomba ukusetshenziswa kakhona kuzo zonke izidingo zokwenza ngaphandle kwezinkinga zokutholakala. Izici zakhe ezincane zokuthwala zithintela ukuthwala okuningi okungakwazi ukuguqula umkhawulo wethimoto noma kwenza izinkinga zezandla ezidlangalalene nezimanzi. Izisebenzo zokwenza zithola imphumela yokuthintele izidingo zokuphatha izimoto, kufana nokunciphisa inani lokucima, lokuphahla, nokuphinda ukulungisa izimoto. Izici zokuphatha zalesi sivimba zixhomekeka ekwenzeni ngokucophelela ngokuthi ziqinisekisa izimo ezifanayo zethimoto ukuthi ziqinisekise ukucophelela kwebhodi nesimo sezandla kumathuba aphazanyisiweyo. Lokhu kukhupha kwenza ukuthi kuthintele izindleko ngokunakekelwa kwezimoto, ukunciphisa izimali ezotholiwa kumathuba, nokunciphisa izinkinga zokusebenza kudinga ukuphatha nokubuyisela izimoto.

Ukusebenzisa Okulungileyo Nenkinga Yekhono

Isivuno sangaphandle se-polyurethane soft foam sivunelwa ngamathula ekuqashini okunjalo akusiza ekusebenzisweni kuzingcindezi zonke izimo zokwakha ngemuva kokugcina imikhuba yobuchwepheshe. Iviskosithi yayo engelekiwe futhi amathulwa esayansi ayicindezela ukuthi kube lula ukuyisebenzisa ngendlela eyahlukene njengezemithombo yespray, ukushayela, nokusebenzisa izixhobo ezihlawulayo ngokuzenzekelayo. Ifomule ishiya isikhathi esincane sokusala ngaphambi kokufaka kwesiphumo esigcweleyo. Lokhu kubalulekile kakhulu emisebenzweni yokwakha okuhlukumezayo apho izinkolo zokwakha zidinga ukuvala kwindawo ngokushesha futhi ukuphazanyiswa okuncane. Ifomule yayo engaphansi kwezwi ikhulula izimo zendlu lesiko futhi ikhuphula izidingo zokuvilima, kusiza ekukhuliseni kwezimali zasekhaya futhi zibukeke kancane. Izenzo zakhe ezingavame ukuba zihluka zifakwa kulo mphumela onjalo ngenxa yokungabi khangelelwa phakathi komsebenzi walo, kungaholelwa kuthinta ubumnandi bomsebenzi noma ukuhlanjulwa kwemisebenzi. Amathulwa okuhlanganisa nezibambiso azidingi ubufakazi obuningi noma izixhobo ezithile. Isivuno sangaphandle se-polyurethane soft foam sinesandla esihlakaniphile yokugcina indawo yakuqasha kanye nenhlaka enkulu efihla inkinga yokuphatha umtholampofu futhi kuthinta kabusha impahla. Ukucopheleka kwazo kumthwalo wamanje akukholiseki izindleko eziningi zokuguquguquka kwayo noma kuthintele ukusebenzela manje. Isilinganiso sakho sobubi sinikeza ukuphazimulwa okuncane kwezinto ezinetyevelo nezincono ezincane okuthuthukisa ukulungiswa kwebhodhi nembono yesitsalisi. Izidingo zokufundisa zilula kakhulu ngoba kunesimo esilungileyo sokusebenzisa futhi sinezimo ephumelelayo ekuvikelweni ukuthintana kwe-ophereyitha ngaphandle kokuthintana ngaphezu kwesiphumo. Umhloniphelelo wakhe wezwe ungcwaliseka ngezinto zakhe ezingavalekanga okuthinta kabusha impahla kodwa kuqinisekisa imikhuba yasendlela okudingekayo kumsebenzi owadingayo.
