Iinkqubo ze-Foam: I-Polyether, i-MDI (i-Isocyanate), i-Oli yeSilicone, i-Catalysts & More!

Ukhe uzibuze ukuba yenziwa njani loo miqamelo mihle, oomatrasi obutofotofo kunye neecushion zesofa? I-foam enika ezi zinto zibalulekileyo ze-snug uhlobo lwazo kunye nokuthamba sesinye isithako esibonakalayo kuyilo lwazo. I-Polyether MDI silicone oyile catalyst njl uhlobo lweyona nkqubo yogwebu iphambili emhlabeni idale isiphithiphithi kwimarike ngenxa yezizathu ezininzi ezifana nozinzo, ukhuseleko kunye nokomelela esiya kubona ngakumbi kwiinkcukacha ezithe vetshe.

Izibonelelo zePolyether, i-MDI, i-Oli yeSilicone, iCatalyst kunye nokunye

I-polyether, i-oyile ye-silicone, i-MDI kunye ne-catalyst ngamacandelo ahlukeneyo enkqubo yogwebu enenzuzo ezininzi xa kuthelekiswa nezinye iinkqubo. Kulungile kwabaqalayo, ukuzinza kwayo okumangalisayo kuthetha ukuba i-foam ihlala ixesha elide kwaye ihlala isenza kumthamo omkhulu. Okwesibini, inkangeleko yokhuseleko lwayo iyancomeka njengoko ingenazo izinto ezifana neeCFCs kunye neeHCFC eziyingozi kwindalo esingqongileyo okanye ebantwini Okokugqibela, ukuziqhelanisa nokulungelelana kwayo kugqame njengoko kuchaziwe kwindlela enokusetyenziswa ngayo kumashishini amaninzi ukusuka kwifanitshala kunye neebhedi ukuya kwiimoto/ ishishini lezothutho nangaphaya.

Ngoku sungula izinto ezintsha kwiPolyether, MDI kunye neSilicone Oli kunye neCatalyst.openConnection

I-polyether, i-MDI, i-oyile ye-silicone, i-catalyst kunye nenkqubo ye-foam iyingqayizivele kwindlela edibanisa ngayo iipolymers ezininzi / i-polyols / i-surfactants ukuze ifake iimpawu ezichanekileyo ze-foaming I-polyether polyols, umzekelo, isetyenziselwa ukuqinisekisa ukuba i-foam ithambile kwaye iphefumula; I-MDI iyenza icinezeleke ngakumbi kodwa kube nzima ukuyikhubaza xa ithelekiswa neoyile ye-silicone enceda ekugqibeleni ukunyusa ukuqina nokuzinza kwayo. I-catalyst isitshixo sokukhawulezisa le ndlela yokusabela, ukulawula ubukhulu be-foam kunye nesakhiwo seseli sokuqinisekisa ukuxinana okuthembekileyo okufanayo.

I-Polyether eKhuselekileyo, i-MDI, i-Oli yeSilicone, iCatalyst kunye nokunye.

Kuphuhliso lwale nkqubo amagwebu, ukhuseleko ibisoloko enye inkxalabo yethu phezulu njengoko siye sasebenza kunye polyethers njl, MDI kakhulu kunye neoli abicah ngokusebenzisa catalysts zonke kwiifom zabo eziyingozi ngakumbi. Le nkqubo yenzelwe ukuba i-eco-friendly ngaphandle kokukhupha izinto ezikhutshwayo ezinobungozi ngexesha lokuvelisa okanye emva kokusetyenziswa. Ukongeza, ayisebenzisi imichiza eyingozi efana neeCFCs kunye neeHCFC ezaziwa ngokuphelisa i-ozone layer - ekhokelela ngokwesiqhelo kubangela iingxaki zokuphefumla. Ukuzinikela okunjalo kukhuseleko kwenza inkqubo ye-foam ibe yindlela ezinzileyo nenoxanduva lwezicelo ezahlukeneyo.

I-Polyether, i-MDI / i-Silicone i-Oli / i-Catalyst: I-Versatility echazwe

Le nkqubo ye-PU, equka i-polyether resin, i-MDI isocyanates kunye neoli ye-silicone ukongeza kwii-catalysts ze-crosslinker zobunzima be-foam enzima ikhusela ezinye iindawo ezinamandla njengefenitshala / ibhedi kunye nokupakishwa; kodwa nalapho uxinaniso okanye ukomelela kuzisa inzuzo le minqamlezo yokufikelela ibanzi nokusetyenziswa kweemoto. Lolona khetho lufanelekileyo lokukhusela, ukuthintela isandi, ukugquma kunye nokutywinwa (ngenxa yokuzinza + ukhuseleko + nokuguquguquka). Ugwebu lunokwahluka ngokobuninzi (ubunzima), ukuqina, kunye nobukhulu ukubonelela ngemfuno ethile okanye ukuva okunqwenelekayo. Ukongezelela, ukuphatha okulula kunye nokusika, okufanelekileyo kwiinketho zokunyusa njl njl ukwenza kube luncedo kungekuphela kwinqanaba lokuvelisa kodwa kunye nabasebenzisi bokugqibela.

Ukusetyenziswa kwePolyether, i-MDI kunye ne-silicone i-oyile catalyst - indlela yokuKhokela

Amanyathelo ekufuneka uwalandele ukwenza ugwebu ngokusebenzisa i-polyether, i-MDI, ioli ye-silicone, i-catalyst kunye nezinye izithako eziseleyo. Le polymer ixutywe kumlinganiselo omncinci we-stoichiometric ochanekileyo, i-polyol, i-surfactant kunye neoli ye-silicone kunye ne-catalyst ukuvelisa i-foam phantsi kwemeko elawulwayo. Indibaniselwano yezi elementi yenza ugwebu oluthi ke lusete kwaye lubunjwe ngokwemilo ethile kunye nobukhulu. Ugwebu lufanelekile ukuba lusetyenziswe lukrwada kuso nasiphi na isicelo, okanye lungasetyenzwa ngakumbi kusetyenziswa namelfaneletion.

Iinkonzo ezifana nePolyether, MDI, Ioli yeSilicone, iCatalyst kunye nokunye okunoMgangatho

I-polyether, i-MDI, ioli ye-silicone kunye nabavelisi be-catalyst yenkqubo ye-foam bonke babonelela ngenkxaso efanelekileyo yobugcisa kunye ne-QA ethembekileyo. Banikezela ngeenkcazo zemveliso eneenkcukacha, amaphepha edatha yobugcisa, kunye nolwazi lokhuseleko ukuze baqinisekise ukusetyenziswa okukhuselekileyo kwenkqubo ye-foam. Iipropati ezenziwe ngokwezifiso ze-foam, ukuhlangabezana nemveliso ethile kunye neemfuno zabasebenzisi Yintoni Esinokuyenza Kuwe? Iimvavanyo ezingqongqo zolawulo lomgangatho kunye nokutshekishwa ukusuka kuvavanyo lomzimba, iikhemikhali ukuya kwiimvavanyo zokusebenza ziphunyezwa ukuqinisekisa ukuba i-foam idlula kwimigangatho echaziweyo kunye neenkcukacha.

Ngoko, kwaye isishwankathelo: ubomi obuninzi be-polyether, i-MDI, ioli ye-silicone ... i-catalysts ... kunye nokunye!

Inkqubo entsha ye-foam esekelwe kwi-silicon equkethe i-polyether, i-MDI okanye i-soybean-based surfactants ye-oyile kunye ne-hybrid catalysts ivela njengeyona ndlela inokuthenjwa, ekhuselekileyo kunye neendlela ezininzi zokusetyenziswa kwe-PU ye-foam yexesha elizayo. Sisisombululo esifanelekileyo kuye nawuphi na umenzi okanye umsebenzisi wokugqibela onqwenela ukusebenza, ukusekwa kunye nobuhlobo bomsebenzisi wexabiso eliphantsi lokuPhathwa kwezinto ezikhethiweyo. Le nkqubo yogwebu ibicinga ngemakethi, kunye nabasebenzisi bayo, kunye nendlela yabo entsha yokuyivelisa kunye bachaza ukuba yeyiphi na isiqinisekiso somgangatho kunye nokhetho olunikezelwayo. Ngexesha elizayo xa uphumlisa intloko yakho kumqamelo ovuthuzayo okanye uzinzise kumqamelo otofotofo wesofa egcwele kakhulu, cinga ukuba inokuba yenziwe yaphila ngepolyether, MDI (methylene diphenyl isocyanate), ioyile yesilicone kunye nearhente enogwebu.
