umshado wokubhiza polyurethane foam

Ukuphakamisha kwezilungiselelo zomoldi lwe-polyurethane foam yi-phrodyekhi yezindlela elizikhoyo olunikezela ukuthi amaphepha angasukele ngaphandle kwezilungiselelo ezimoldweni. Lolucazelo olusandiswa lokhu lulandelayo luhluke umphatho omncane phakathi komdlobheni womoldi neziphetho zomaterial, uzokubona ukuthi akukho ukwesuka kodwa uhlanganisa ukuhlawulwa lwemvelo wophrodyekhi olufanayo. Umphathisi wokuhlawula lukhishwe ukuba alenze isenzo esidingayo ngaphakathi komdlaba wesigaba lesiphephile nokuhlola ngendlela engahlukene, futhi ngenxa yalokho kukhona ukusetyenziswa kakhulu ngokubanzi kuzo zidlobo eziningi neziphetho ezinomsindo zomaterial we-polyurethane foam, ukuba kunqume kakhulu ngokusebenza kuzo izindlela eziningi zokugcina. Lokhu kulandelayo kuhluke iindlela ezininzi zokusetshenziswa, ngokushesha, ukubuyiselana okanye ukubhukuda, ngokumelene nazo zimpahla zokugcina. Iphrodyekhi emodeni luchasene ngezinye izinto ezingazange zibonakeleyo kuzo amandla azikhethekileyo ngokusebenzela ukuthi amandla amaningi ahlawuliwe ngaphambi kokuthi kuhluleke imitha yesicelo nokuthi akukho ususo wemateriyel. Lokhu kusetyenziswa ukuba alandele amandla amaningi ngokusebenzela ukuthi akukho ususo wemateriyel wemoldi, lokhu olungabonakaleyo ukuthi uhlanganisa izinsuku ezincinci eziphakamiswayo nemvelo wemphrodyekhi nokuhlola ngempahla. Amaphrodyekhi amadala amalindele nomdlalo omkhulu okanye omncane nokuba beselelwe ngokukhulu ngokusebenzela ngaphakathi komdlalo omncane okanye omkhulu, futhi kungasebenzi ngokukhulu ngokuphambili komhlabulo wenyawo uphinde uphambili kwi-200°C. Ukusethenziswa luchasene ngezinye izinto ezikhethelwe yokuthi zingaqondisisa ukusebenza ngokubanzi ngaphakathi komdlalo wesicelo, ukuba kuhlonipheka kakhulu ngokusebenzela kuzo izindlu ezintathu.

Umbono omphakathi wokufunda isililo sokuqinisekisa polyurethane esikhulu kusenzela ukuthi kuhluke amandla okuyimfihlo ongaphambili lokusebenza nokuhlola kwezinto ezikwenene. Abasebenzisi bayibhidisa ngokubanjwa imitha yezikhefu ngoba zingavamele kunye nesivumelwano esincane esifika kuzilimi, uzokususa ukunikezwa ngokushesha okanye ukulungiswa. Ukuphawula kakhulu kwezinto eziphumuleleyo kwezililo zisongezelela ukuthi umthengiso omncane ofanelekile lizigcine lelilo lokungabiko, ukuze zikholele izinto eliphephile kunye nokukhobosha kwemiphumela. Umbono wesilinganiso wesikhangeli kuhluke amandla okuyimfihlo ongaphambili lokusebenza ngokuba iindlela ezimbini ezindala zaziphumelela amandla angaphezu komthengiso, uzokususa ukusetyenziswa kwamathetho kunye nokusetyenziswa kokugcina. Iindlela yokuphuma akukho ukuphuma ukubhalela ukuthi amandla afinyelewe apho afanele ngaphandle kokubhalela noma ukusuka kwisekhelo somphakathi. Umbono wendlela yokubaluleka kuhluke amandla okuyimfihlo ongaphambili lokusebenza ngokuba iindlela ezinhlahla ezindala zaziphumelela ukuthi zikhohlwe inani lemfihlo lokusebenza ngazo ngexhasi elidingekileyo. Umbono wendlela yokubaluleka wakhiwe ngokubanjwa ngokuthi ubanjwe ngokuncane ukuthi akubhekise ukuthi amandla aziphumelele ngexhasi elidingekileyo, uzokususa ukuthi amandla akhohlwe inani lemfihlo lokusebenza ngazo ngexhasi elidingekileyo. Ukuphuma kweendlela yokubaluleka kuhluke amandla okuyimfihlo ongaphambili lokusebenza ngokuba iindlela ezimbini ezindala zaziphumelela amandla angaphezu komthengiso, uzokususa ukusetyenziswa kokugcina kunye nokusetyenziswa kokugcina. Ukuphuma kweendlela yokubaluleka kuhluke amandla okuyimfihlo ongaphambili lokusebenza ngokuba iindlela ezimbini ezindala zaziphumelela amandla angaphezu komthengiso, uzokususa ukusetyenziswa kokugcina kunye nokusetyenziswa kokugcina.

Ukuphuculeka Kwesikhatsi Esiphuthumana

Ukuphawula okubonakaleyo kwezindlela ezifanayo lomgca wokulayisha weziqhuthu lepolyurethane foam imold release agent ifanele yisisekelo somtheleli wezimolekule zokuqala, ezikhetha isiphumo sibonakali phakathi komphathisi wesikhephe nokumateriali weziqhuthu. Ukufomula okukhusela lokunikeza amakhosi kunokuyithumelela ngasemva kwindlela yokususa ukususa kwesikhephe, ukuze uhlobo lokuhambisana ngekhono lokusebenza kulandelwa kwindlela yokususa. Imgca wokulayisha wenze umthengamo omncane, omicroscopic ofanelekileyo ongenziwa ukusuka kwiimbuzo eminingi, ukuze uphawuleze ukusebenza ngokuzenzekelayo ngaphandle kokuhlola kuqaphelwe. Leliqiniso lokungaphezulu kuhlanganisa ukusebenza ngokuphi ndawonye kodwa kuhlelwa ukususa ukususa lokuncedisiwe kwezindlu nezintambo ezilayishwayo. Isichemistry esingabangako lenyushelwe ukusebenza ngokubona nomdlalo ngazo zezinye iziqhuthu ezidingeki lefoam, ukuze ibe yimpilo engakwazi ukusetyenziswa ngokubanzi kwezindlela ezidingeki zokugcina.

Ukulandelela Kwesiphiwo Sesicelo

Ukuphatha kwezinto liphathwa ngakuvumelwa ngokushesha ngenqanawe lwe technology yomold release ethi amadala. Umgca wokugcwaliswa okwesusa ukungafuneka imizuzu emagcinisweni lokusebenza, ukuze kuhamba kakhulu amacyikli zokusebenza nokuthuthukisa umthentho wokuqapheleka. Iziphiwo ezikhoyo kweproduksi zisongeza ukuthi usetyenziso osingabhedwayo sihlale sithole amandla angaphambili lokusetyenziswa, ukusuka kuhlanganisa ukusetyenziswa kwamanye amandla nokulayezela olufanelelwa ngokubonisa ukusetyenziswa kokuthola amandla. Ukusetyenziswa okusasibhedwayo komold release kusongeza ukuba akuzingene izidingo zomold esiqinileyo, okungakungena ukuthi kuhlanganise amandla asebenzayo nokuhlola lokuhlola nomold. Lolu hlobo lokusetyenziswa kusongeza ukuthi amahlaba angazange azihlabeleke, ukusuka ukuthi akuzange asetshenziswa amandla amanye nokuthi kuhlanganise amandla asebenzayo nokuhlola lokuhlola nomold. Ukusetshenziswa kweproduksi kunjalo kuhlanganise amandla amanye nokuthi kuhlanganise amandla asebenzayo nokuhlola lokuhlola nomold.

Ukuphumelela nokuhlola isibhedlela

Lokho lokuhlola imoldi yomfo yasepolyurethane lavela ngokubekwa kusukelelwa ukuvumela amandla okanyekezayo ezifanekiso zokudla nokuhlola esisodwa singezantsi ukuba akhuse inqubo yokulayishwa. Ukuphakamiswa kokuthi kuhluke i-VOC iyahamba ukufinyelela izigaba zokudla zokuxhasa ukuba zikhulume neziqhawu ezinomsindo emidvini. Ukungakhotholiweyo kwehluko lokwesibhedlela kuhlela ukukhipha nokugcina izicwangciso, uzokususa amaphrojekti asebenzelo nokuthi aziphindze amagama amancane amaphandle komoya. Ukungakhotholiweyo kwehluko lokwesibhedlela kuprotekisa noma umkhosi wakwabo nokunye unyathi, futhi ukuthi alithathe umoya omncane uphinde uhlele ukusuka kwesikhashana. Ukuphakamiswa kokuhlola lokhu lokuhlala ngokulandelakala kunikeza izigaba zokudla zokuxhasa zokwenza izimpahla zakhe zokuthatha ukuhlola ngokulandelakala ngakho athole amandla angaphambili nokuhlola ngokulandelakala ngakho apho ayihlobene ngephrojekti nokuhlola ngokulandelakala.
