Indlela yokusebenza komlawuli we-foam

I-foaming regulator sisixhobo esisetyenziswa kakhulu ngamakhemikhali, esidlala indima ebalulekileyo kwizicelo ezininzi zoshishino, ingakumbi ekwenziweni kweplastiki ye-foam kunye nezinye izinto eziqulethe amaqamza. Ezi zilandelayo zezona ndlela ziphambili zokusebenza kwe-foaming regulators:
Nciphisa uxinzelelo lomphezulu wolwelo
Izilawuli ze-foam zihlala zi-surfactants ezinokunciphisa kakhulu uxinzelelo lomphezulu wolwelo. Olu phawu lwenza kube lula ukuba ulwelo lwenze amaqamza azinzileyo. Xa izilawuli ze-foam zongezwa kulwelo, zenza ifilimu encinci kumphezulu wolwelo ethintela iimolekyuli zomoya ukuba zingangeni ngaphakathi kolwelo. Xa ulwelo luxutywa okanye lushukunyiswa ngamandla angaphandle, umoya uya kubanjwa kulwelo, wenze i-foam 1.
Yenza igesi
Ezinye iintlobo zezilawuli zokukhupha amagwebu, ingakumbi ii-arhente zokukhupha amagwebu eekhemikhali, zivelisa iigesi ngeempendulo zeekhemikhali. Ezi gesi zenza amaqamza kulwelo, nto leyo evelisa amagwebu. Ukusetyenziswa kwe-arhente yokukhupha amagwebu eekhemikhali kufuna ulawulo oluchanekileyo, kuba igesi egqithisileyo inokubangela ukungazinzi okanye ukuqhekeka kwegwebu.
Ukufutha ngokwasemzimbeni
Ukongeza, ezinye ii-foam regulators zingenisa igesi kulwelo ngeendlela ezibonakalayo, ezinje ngokuxukuxa okanye ukucheba ngesantya esiphezulu, ukuze kwenziwe i-foam. Le ndlela idla ngokufuna izixhobo kunye neendlela ezikhethekileyo ukuqinisekisa ukuba igesi inokusasazwa ngokulinganayo kulwelo.
Phucula ulwakhiwo lweseli kunye noxinano lwefoam
Kwimveliso yezinto ze-polymer foam, abalawuli be-foam banokuphucula kakhulu ulwakhiwo lweseli kunye noxinano lwe-foam. Ngokulungisa uhlobo kunye nobungakanani bomlawuli we-foam, inqanaba lokwandiswa kunye nolwakhiwo lweseli ye-foam ye-polymer zinokulawulwa ngokuchanekileyo, ukuze kufezekiswe ukusebenza okufunekayo. Umzekelo, i-meta polyanhydride inokulungisa ulwakhiwo kunye nobungakanani beseli ye-low-density foam, ngelixa i-phenolic resin inokulawula ukwandiswa kwe-polymer kunye nolwakhiwo lwe-foam2.
Phucula amandla okunyibilika kunye nokuhamba kakuhle kwamanzi
Enye yeenjongo zokongeza iipolymers ezinobunzima obukhulu kakhulu kwiimveliso zefoam zePVC kukuphucula amandla okunyibilika kwezinto zefoam zePVC, ukuthintela ukudibana kwamaqamza, kunye nokufumana iimveliso ezinefoam efanayo. Kwangaxeshanye, oku kuqinisekisa ukuba i-melt inokuguquguquka okuhle ukuze ifumane iimveliso ezibukeka kakuhle.
isiphelo
Abalawuli be-foam basebenza ngeendlela ezahlukeneyo, kuquka ukunciphisa uxinzelelo lomphezulu wolwelo, ukuvelisa igesi, ukushukuma komzimba, kunye nokuphucula ulwakhiwo lweseli kunye noxinano lwe-foam. Ezi ndlela zisebenza kunye ukwenza abalawuli be-foam badlale indima ebalulekileyo ekuvelisweni kweendawo ezahlukeneyo, ezinje ngokutya, izinto zokuthambisa, iikhemikhali zemihla ngemihla kunye nezixhobo ze-polymer foam. Nangona kunjalo, xa kusetyenziswa abalawuli be-foam, kufuneka kuqwalaselwe nempembelelo yabo kwindalo esingqongileyo, ukhuseleko, kunye neendleko ukuze kufezekiswe uphuhliso oluzinzileyo.
