Umehluko phakathi kwegwebu leseli elivuliwe nelivaliwe

Iyini igwebu leseli elivulekile kanye negwebu lamaseli avaliwe?
Igwebu le-Open-cell kanye ne-closed-cell foam yizo zombili izinhlobo ze-foam material. Zinezinhlobo ezahlukene zezimbotshana eziphefumulayo, ngakho izakhiwo zazo ezingokomzimba kanye nezicelo nazo zihlukile.Igwebu elivulekile leseliibhekisela enanini lama-pores, ama-pores angaxhunywa, futhi umoya ungangena futhi uphume ezintweni ze-foam; futhi i-foam yeseli evaliwe ayikho ku-foam; kunezimbobo, ngakho-ke umoya ngeke ungene futhi uphume egwebu.

Umehluko Ezimpahleni Zomzimba
1. Ukumuncwa kwamanzi
Igwebu elivulekile leseli alinawo ama-pores avaliwe, okuholela ekumunceni okunamandla kwamanzi futhi akwenze kungafaneleki ukumuncwa umswakama. Ngakolunye uhlangothi, igwebu elivaliwe-cell alinawo ama-pores futhi alimumbi amanzi, ngakho-ke lingasetshenziswa ekuvimbeleni amanzi.
2. Ukuminyana
Ukuminyana kwegwebu lamaseli avulekile ngokuvamile kuphansi kunegwebu lamaseli avaliwe, futhi ngenxa yokuba khona komoya endabeni, ukunwebeka kwegwebu leseli elivulekile kunamandla kunaleloigwebu lamaseli avaliwe.
3. Ukuvumeleka
Ngenxa yezimbobo zayo zokungenisa umoya, ukuvuthwa kwegwebu elivulekile-cell kungcono kunokwegwebu elivaliwe-cell, elingasebenzi emkhakheni we-insulation sound, futhi ngaleyo ndlela ingasetshenziswa kuphela emkhakheni wezinye izidingo zokulondoloza ukushisa noma ukupholisa.

Umehluko ekusetshenzisweni
Ngenxa yezakhiwo ezihlukene zomzimba, igwebu elivulekile leseli kanye negwebu lamaseli avaliwe ahlukile emikhakheni yohlelo lokusebenza.
1. Vula igwebu leseli
Ukusetshenziswa kwegwebu le-open-cell kubanzi uma kuqhathaniswa, ikakhulukazi emkhakheni we-thermal insulation noma ukupholisa, njengemishini yokufaka ukushisa okushisayo, ukubumba ukukhiqiza, neminye imikhakha.
2. Igwebu leseli elivaliwe
Amagwebu eseli elivaliwezisetshenziswa kaningi kunamagwebu amaseli avulekile ngenxa yokuthi amelana kakhulu namanzi kunamagwebu amaseli avulekile. Ngenxa yekhono layo lokungangeni manzi, igwebu elivaliwe lisetshenziswa emishinini yezemidlalo yamanzi, emishinini yemidlalo yamanzi, nokunye ukuvikela amanzi kanye nemishini esindisa ukuphila.

Umehluko phakathi kwegwebu le-open-cell kanye ne-closed-cell foam ukuthi izakhiwo zabo ezingokomzimba nezinhlelo zokusebenza ziyehluka.Igwebu elivulekile leseliisetshenziswa emkhakheni we-thermal insulation kanye nokupholisa, kuyilapho i-foam-cell evaliwe isetshenziswa emkhakheni wezemidlalo yamanzi, ukuvikela, nokusindisa ukuphila.
