I-Fomu lePU elikhethwe ngokuthiwe: Isiphumo Sokuqala Sokuthengiswa Kwisimavu

Zonke Izigaba

umphawuli wemfomu yePU esikhishweni

Umphawu wokubhekisa i-Rigid PU foam yehlukene ngenqanawe yichemical compound elungileyo olunikezela ukuthi uhlale kakhulu ukususa amagama a-polyurethane foam apho zizikhishwe ezindlela zokusebenza. Leli lisekwi-ndlela siphakeme phakathi kwezinye izinto eziphakeme kanye nezi-formulation ezidingekileyo ukuba le qinisekiso lokubhekisana. Umphawu wokubhekisa ubheke umdlalo omncane okufuneka ukususa ukubhala ngaphandle kokuhlula ngendlela enhlangeni yokugcina umbala wesintsho wesilimi sokugcina. Wavulwa ngokuphi ndawonye ukuba alibheke ngokuthi akwazi ukususa isintsho sesilondolozo nokuphakeme kwekhonjane ekhona kanye nokuphakeme kwesintsho sokugcina. I-technology esiqinisekiseyo lokwenzeka lokubhekisa kuhlonipha izinkinga ezimbili ezihlangene nokusebenza, kuhluke amacycle times, ukusebenza kakhulu kodwa kumodeling, kunye nokuhlola kakhulu komphawu. Zithegiwe ukuba zifinyelele amandla ngokubanzi ngazo emigomo yezitemperatures kunye nezi-processing conditions, ukuba zisebenze ngokukhululekile kwindawo ye-continuous kunye ne-batch production environments. Ukusetyenziswa okungavumelekile kwe-Rigid PU foam release agents uhamba kakhulu ngazo izindawo eziningi, kuhluke imithombo yebhuthi, i-automotive components, i-insulation panels, kunye ne-refrigeration equipment manufacturing. Izifomu ezintsha zinikezela ukuba zibe ngokulandelana nesethulo, ngazo amandla angaphezu kokuqinisekiswa kwe-VOC kunye nokuhlola kakhulu kwezinhloko.

Umnikazi wokulayisha olushesha ekuphakamisweni luhlu kakhulu lomphathiso ezininzi elizikhona ngaphandle kokuthi yilungu lokuhlola. Ngokuqinileyo, uyahlola isibhedlela sokugcina ngesiphumo esikhundleni nokuthi amaphepha angavamekanga ngaphandle komlayezo, uhlala okuncane lokusebenza ukusukela nokuvumela izidingo zokusebenzela. Iziphawu zokubhala nokubhala okunene ngezihlobo ezifanayo zikuhlola umkhakha omphambili, uzokusetyenziswa kwesiphi esinye sesixhasa, ukuhlola iimpendulo engaqondweni, uzokusetyenziswa kwezinhlelo ezinethuthuko. Abasebenzisi bahlatywa ngokuthi imlayezo yakwabo ayiqale inncinci ngokuthi umnikazi wokulayisha uhlonela lokuhlula phakathi komlayezo nokukholelwa, ungene kuqhathaniso okukhulu lokusebenzela lokuhlola lokuhlula komlayezo nokufinyelela komlayezo. Ukuphumelela kwezindlela eziningi lokusebenzela kanye nezinye izigama lezimlayezo nokugebhuza, ungene kuhulumeni lokuhlola lokuhlula komlayezo ezingxenye ezintshangayo. Izindlela ezimbini zitholakala izindima zokuduya ngqukuze kuthiwa amalayishini akhululeke ngokuthi abebe ngaphandle kwezinsuku ezinikezeli, ungene kuhulumeni lokuhlola lokuhlula komlayezo ezingxenyeni ezinikezeli, uzokusetyenziswa kwezinhlelo ezinethuthuko. Ngokwesiko, umnikazi wokulayisha uhlonela lokuhlola umkhakha omphambili kwiimpahla emva kokuthi amaphepha angavamekanga ngaphandle komlayezo, uzokusetyenziswa kwezinhlelo ezinethuthuko. Ngokwesiphiwo, umnikazi wokulayisha uhlonela lokuhlola umkhakha omphambili kwiimpahla emva kokuthi amaphepha angavamekanga ngaphandle komlayezo, uzokusetyenziswa kwezinhlelo ezinethuthuko. Umnikazi wokulayisha uhlonela lokuhlola umkhakha omphambili kwiimpahla emva kokuthi amaphepha angavamekanga ngaphandle komlayezo, uzokusetyenziswa kwezinhlelo ezinethuthuko.

Ukufakwa nokusebenza kakhulu nesibhedlela esikhangelini

Ukuphakamisha okungapheliweyo kwezilungiselelo lokususa esikhakhulweni sokuqinisekisa i-PU foam release agent kukhombisa ngokwesiphi esikwangempela, ukuze kube ngenxa yokuziphatha kwezinhlobo zokugcina. Le ngezi luhlukile ngokusebenza ukubuyekeza okuthile lokusebenza olunxibeleleyo oluncane lokusebenza lokuhlukiswa umoya wosizo nokumathalaza, ukuze kuhlobene amaxwebhu emfunyaneni ne-material yomoya. I-release agent ibeke izifilimi ezimicroscopic ezincinci ezikhulu ezihlukiselela ngokupheleleyo ngaphandle kokususa, ukuze zibeke amandla njengamanje ngaphandle komoya wokususa, uzame ukususa ngokupheleleyo phakathi kwemold surface okanye emdluleyo. Ukusebenza okungapheliweyo kunyatheliswa ngokupheleleyo, kuhluke ukuba iminyaka yesayensi zihlanganisiwe, ukusuka kancane lokufakwa lokudemoulding nokushintsha kwezinyathelo ezidingekayo ngenxa yokususa. Izigaba zokusebenza zihlanganiswe ngokupheleleyo kwi-molds ezindabeni apho amarelease agents ephakathi akuyazi ukubuya nokususa ngokupheleleyo.

Ukuphakama Kwesikhatsi Ngenkinga Lokusebenza

Ukuphawuliwe kwezilondolozi zokulanda izimo elibhedlela lwePU yonqanawa okuyindlebekeka ngokukhangelwa kakhulu lokulandela uqukuquma kwiziqu lezindawo. Ukufakelwa kukwahlula amapolimeri asesikhashana kunye noma amagama ezingamathathu ezikhetha ukuba kuhle umphawulo wokulanda ofanele nokuthi akwazi ukusuka ngokubhedelelwa ngeminyaka engaphezulu emanzini. Lolu hlobo lokuphawulwa kulandela phakathi komkhomboti wesikhephe, okungafanele ukuba kuhle ukuba kuhlalele isikhatsi esidingeni sokuthatha amandla, lokunje ngaphandle kokuthi kube neziphumo ezinomsindo. Izinqumo zokuproteketa zeziqhamo zingabizwa ngaphandle komhlaba wazo oluhlinzekelayo, uzokusiza ukuproteketa iziqhelo zesikhephe kwiimbiza yokugcina kunye nokuzihlela ngokushesha. Lolu hlobo lokuproteketa lichaza ukuba kuhle ukuba kuhlalele isikhatsi sesikhephe sokuthi siphumeleyi, kuhle ukuba kuhlalele isikhatsi somlando, kunye nokuhlala phakathi komncedisi omncinci wokuqala kunye nokuthatha imali ekubaluleneyo. Iziphumo zokumoya zingazange zikhona ngaphandle kokuba kuhle ukuba kuhlalele isikhatsi somncedisi womdlalo kunye nokuthatha umdlalo omncinci wokubheka nokubheka.

Ukhankanyo kwezinyathelo zokuhlola kanye nezilungiselelo zokuhlola

Izihlobo ezimbili zokuthengisa amafomu wePU ezikhethwe ngokulandelayo kwiqhakamsetsheni lokuhlola izinto ezingeneyo nokuhlola ukusiphiso kwabantu abasebenzayo. Ukubuyisela kwenziwe ngokusebenza i-chemistry esijikiweyo okugcina ukuphakamiswa kokuthi imibuzo yezinto elandelwayo (VOC) ngenxa yokuhlola lokunquma umsebenzi wakho. Ukukhululeka ngezinto ezingeneyo kufanelelwa ngokushesha ukusetyenziswa kunye nokungaphandle komoya ofanayo. Izinsuzo zokuhlola zifaka amaxabiso akhangeleyo, umoya omncane nokuthi amaqhawekazi angayiphathekeleleyo okugcina ukukhokha isiko lokusebenza phambi kwekuthiweni. Umgibe wokubuyiswa wathintelela ukuba lichashe noma liqale kulokuhlobisana nezilungelo ezidingekiweyo ezithile nokuhlola izinto ezingeneyo ngendlela eyayiqhubeka noma uzame ukuthi uhlola ukuthengiswa kakhulu. Loku kuxhasa kwezinto ezingeneyo nokuhlola kufanelelwa ngokwesikhatsi sokuthi iningi lokuhlola nokuthi umsebenzi wakho usiphise ukuthi ungene kwindawo yokuthi uma ufunda izilungelo zokuhlola nokuthi ubuyekeze ukusiphiso kanye nokuhlola ukusuka kwezinhlangano zokuthiwe nokuhlola ukusiphiso kwezinye.
