Umahluko phakathi kwe-foam yeseli evulekileyo nevaliweyo

Yintoni i-foam yeseli evulekileyo kunye ne-foam yeseli evaliweyo?
I-foam yeseli evulekileyo kunye ne-foam yeseli evaliweyo zizo zombini iintlobo zezinto ezinogwebu. Zineendlela ezahlukeneyo ze-pores eziphefumulayo, ngoko ke iipropati zabo zomzimba kunye nezicelo zikwahluke.Vula i-foam yeseliibhekisela kwinani le-pores, i-pores inokudibaniswa, kwaye umoya ungangena kwaye uphume kwizinto eziphathekayo ze-foam; kwaye i-foam yeseli evaliweyo ayikho kwi-foam; kukho imingxuma, ngoko umoya awuyi kungena kwaye uphume kwi-foam.

Umahluko kwiiPropati zoMzi
1. Ukufunxwa kwamanzi
I-foam ye-open-cell ayinayo i-pores evaliweyo, ekhokelela ekufunxeni kwamanzi anamandla kwaye iyenze ingafaneleki ukufunxa umswakama. Ngakolunye uhlangothi, i-foam evaliweyo i-foam ayinayo i-pores kwaye ayifuni amanzi, ngoko ingasetyenziselwa ukuthintela amanzi.
2. Ukuxinana
Ubuninzi be-foam yeseli evulekileyo buphantsi ngokubanzi kune-foam yeseli evaliweyo, kwaye ngenxa yobukho bomoya kwizinto eziphathekayo, ukuqina kwe-foam evulekileyo yomelele kunoko.i-foam yeseli evaliweyo.
3. Ukufikeleleka
Ngenxa yemingxuma yayo yokungena umoya, ukunyanzeliswa kwe-foam evulekileyo ye-foam ingcono kune-foam evaliweyo, engasebenziyo kwintsimi yokugquma isandi, kwaye ngaloo ndlela inokusetyenziswa kuphela kwintsimi yeemfuno ezithile zokugcinwa kobushushu okanye Ukupholisa.

Umahluko kwisicelo
Ngenxa yeempawu ezahlukeneyo zomzimba, i-foam evulekileyo kunye ne-foam evaliweyo iyahluka kwiinkalo zesicelo.
1. Vula i-foam yeseli
Ukusetyenziswa kwe-foam ye-open-cell kubanzi, ngakumbi kwintsimi yokufakelwa kwe-thermal okanye ukupholisa, njengesixhobo sokufakelwa kwe-thermal, ukubumba ukuvelisa, kunye nezinye iindawo.
2. I-foam yeseli evaliweyo
Amagwebu eeseli ezivaliweyozisetyenziswa rhoqo kunamagwebu eeseli ezivulekileyo kuba ziyakwazi ukumelana namanzi kunogwebu lweseli evulekileyo. Ngenxa yobuchule bayo bokungabi namanzi, i-foam evaliweyo isetyenziselwa izixhobo zemidlalo yamanzi, izixhobo zemidlalo yamanzi, kunye nokukhusela amanzi kunye nezixhobo zokusindisa ubomi.

Umahluko phakathi kwe-foam ye-open-cell kunye ne-foam-cell evaliweyo kukuba iipropati zabo zomzimba kunye nezicelo ziyahluka.Vula i-foam yeseliisetyenziswe kwintsimi ye-thermal insulation kunye nokupholisa, ngelixa i-foam evaliweyo isetyenziswa kwibala lemidlalo yamanzi, ukhuseleko kunye nokusindisa ubomi.
