Umehluko Phakathi Kweseli Elivaliwe Neseli-Open-Cell Spray PU Foam

I-spray polyurethane foam (SPF) i-insulation iyindlela enhle kakhulu yokugcina ikhaya lakho noma isakhiwo sezentengiselwano sivaleleke ngendlela efanele. Inikeza ukumelana nokushisa okuphakeme, ukuvala uphawu komoya, nokulawula umswakama uma kuqhathaniswa nezinto ezivamile zokufakwa ngaphakathi. Uma kukhulunywa ngokufakwa kwe-SPF, izinhlobo ezimbili ezijwayelekile amaseli avaliwe kanye ne-open-cell spray polyurethane foam. Bobabili banezici zabo eziyingqayizivele nezinzuzo, ezibenza bafanelekele izinhlelo zokusebenza ezahlukene. Kulesi sihloko, sizocubungula umehluko oyinhloko phakathi kwegwebu le-PU yeseli evaliwe neselivulekile ukuze sikusize wenze isinqumo unolwazi ngezidingo zakho zokuhlanganisa.

Isakhiwo Seseli Elivaliwe Neseli-Open-Cell Spray PU Foam

Igwebu le-polyurethane elifuthwa ngamaseli avaliwe liwumsebenzi ominyene futhi oqinile oqukethe amaseli avaleleke ngokuphelele kwamanye. Lesi sakhiwo samaseli avaliwe sinikeza igwebu izindawo ezinhle kakhulu zokuvikela futhi senza ukuthi imelane nokungenwa kwamanzi nomswakama. Ngokuphambene, igwebu le-open-cell spray polyurethane linamaseli avulekile futhi axhumene, okuholela entweni ethambile futhi evumelana nezimo. Nakuba igwebu leseli elivulekile alikwazi ukumelana namanzi njengegwebu lamaseli avaliwe, linezinto eziphakeme zokudambisa umsindo.

Uma kuziwa ekufakweni, igwebu leseli elivaliwe livamise ukusetshenziswa kuzindlalelo eziwugqinsi ngenxa yokuminyana nokuqina, kuyilapho igwebu leseli elivulekile lisetshenziswa ngezandlalelo ezizacile ukuze kuzuzwe amazinga afiswayo okufakwa ngaphakathi. Zombili izinhlobo zegwebu ziyakhula ngemva kokufaka isicelo ukuze zigcwalise imifantu, izikhala, nama-voids, zinikeze umgoqo womoya ongenazihibe osiza ukuthuthukisa ukusebenza kahle kwamandla kanye nekhwalithi yomoya wasendlini.

Izakhiwo Zokuvikela Zeseli Elivaliwe kanye ne-Open-Cell Spray PU Foam

Omunye umehluko oyinhloko phakathi kwegwebu lamaseli avaliwe kanye ne-open-cell spray polyurethane yizindawo zabo zokuvikela. Igwebu leseli elivaliwe linenani elingu-R eliphakeme ngeyintshi ngayinye uma liqhathaniswa negwebu leseli elivulekile, okulenza lisebenze kangcono ekuvimbeleni ukudluliswa kokushisa. Leli nani eliphakeme le-R lisho ukuthi igwebu lamaseli avaliwe linganikeza ukonga okukhulu kwamandla kanye nokunethezeka kokushisa ezakhiweni.

Ukwengeza, isakhiwo esiminyene segwebu elivaliwe silivumela ukuthi lengeze amandla esakhiwo ezindongeni nophahla, okulenze libe lilungele izindawo ezidinga ukwesekwa okwengeziwe. Imvelo eqinile yegwebu lamaseli avaliwe futhi iyasiza ekuvimbeleni ukuvuza komoya kanye nokungena komswakama, okudala isixazululo esiqinile nesihlala isikhathi eside.

Ngakolunye uhlangothi, igwebu le-open-cell spray polyurethane linenani eliphansi le-R ngeyintshi ngayinye kodwa liyisivikelo esihle kakhulu ngokumelene nokudluliswa komsindo. Ukwakheka kwayo okuthambile nokuguquguqukayo kuyivumela ukuthi ivumelane nokwakheka okungajwayelekile kanye namakhonsathi, okuyenza ibe inketho ekahle yokuvalela izindawo okunzima ukufinyelela kuzo. I-Open-cell Foam nayo ibiza kakhulu kunegwebu leseli elivaliwe, okwenza kube ukukhetha okudumile kumaphrojekthi aqaphela isabelomali.

Izakhiwo Zokuvimbela Umswakama Zeseli Elivaliwe kanye ne-Open-Cell Spray PU Foam

Igwebu le-polyurethane lesifutho seseli elivaliwe laziwa ngezakhiwo zalo ezinhle kakhulu zokuvimbela umswakama, okulenza libe yinketho ekahle ezindaweni ezithambekele ekungeneni emanzini, njengendawo yangaphansi nezindawo zokukhasa. Ukwakheka kwamaseli avaliwe wegwebu kuvimbela umhwamuko wamanzi ukuthi ungangeni, unciphise ingozi yokukhula kwesikhunta kanye nesikhutha.

Ngokuphambene, igwebu le-open-cell spray polyurethane i-vapor-permeable, evumela umhwamuko ukuba udlule ezintweni. Nakuba lokhu kungase kube yingozi ezindaweni ezinomswakama, kungasiza futhi ukuvimbela ukunqwabelana komswakama emigodini yodonga, kunciphise ingozi yokufingqa kanye nomonakalo ohlobene nomswakama.

Kokubili igwebu le-PU lamaseli avaliwe kanye neseli elivulekile lingasiza ukuthuthukisa ikhwalithi yomoya wasendlini ngokuvimbela ukungenwa kwezinto ezingcolile zangaphandle kanye nezinto ezingezwani nazo. Ngokwenza uphawu olungangenisi umoya, ukufakwa kwegwebu lokufafaza kungasiza ukunciphisa okusalungiswa, ukuthuthukisa ukulawulwa kwezinga lokushisa, futhi kwandise ukunethezeka okuphelele endaweni yakho yokuhlala noma yokusebenza.

Umehluko Wezindleko Phakathi Kweseli Elivaliwe kanye ne-Open-Cell Spray PU Foam

Uma kukhulunywa ngezindleko, igwebu le-polyurethane le-closed-cell spray ngokuvamile libiza kakhulu kunegwebu leseli elivulekile. Ukuminyana okuphezulu kanye nezakhiwo ezivikelayo zegwebu lamaseli avaliwe zifaka isandla endaweni yayo yentengo ephezulu, okuyenza ibe inketho yokufaka i-premium kulabo abafuna ukonga amandla esikhathi eside nokuqina.

Igwebu le-open cell spray polyurethane, ngakolunye uhlangothi, libiza kakhulu futhi linganikeza ukonga amandla okubalulekile ngokuhamba kwesikhathi. Ukuminyana kwayo okuphansi kanye nezindleko zempahla kuyenza ibe yinketho ethandwayo kuwo womabili amaphrojekthi wokufakwa kwezindlu zokuhlala kanye nezohwebo lapho izithiyo zebhajethi ziyisici.

Kubalulekile ukucabangela izinzuzo zesikhathi eside zokufakwa kwegwebu lesifutho lapho unquma phakathi kwegwebu leseli elivaliwe kanye neseli elivulekile. Nakuba igwebu lamaseli avaliwe lingadinga ukutshalwa kwezimali okuphezulu kwangaphambili, izakhiwo zalo eziphakeme zokuvikela umswakama, ukumelana nomswakama, nokusekelwa kwesakhiwo kungase kubangele izikweletu eziphansi zamandla nezindleko zokuyilungisa ngokuhamba kwesikhathi. Igwebu lamaseli avulekile, nakuba lithengeka kakhudlwana, lingadinga ukuphinda lifakwe kaningi noma ukuvikela umswakama okwengeziwe ezindaweni ezimanzi.

Isiphetho

Sengiphetha, i-polyurethane foam yamaseli avaliwe kanye ne-open-cell spray ngayinye inezinzuzo zayo eziyingqayizivele kanye nokusetshenziswa kwayo uma kuziwa ekufakeni. Igwebu lamaseli avaliwe linikeza ukusebenza kahle kwamandla okuphezulu, ukumelana nomswakama, nokusekelwa kwesakhiwo, okuyenza ibe ukukhetha okuhle kakhulu ezindaweni ezidinga ukufakwa okuphezulu nokuqina. Igwebu elivulekile leseli, ngakolunye uhlangothi, lihlinzeka nge-insulation engabizi kakhulu, ukudambisa umsindo, nokuguquguquka, okulenze lifanelekele izinhlobonhlobo zemiklamo yokuhlala neyokuhweba.

Ekugcineni, ukukhetha phakathi kwegwebu le-polyurethane ye-val-cell kanye ne-open-cell spray kuzoncika ezidingweni zakho ezithile zokuhlanganisa, imikhawulo yesabelomali, kanye nezidingo zephrojekthi. Ukubonisana nosonkontileka ochwepheshile we-insulation kungakusiza ukuthi uthole uhlobo olungcono kakhulu lwegwebu lesakhiwo sakho futhi uqinisekise ukufakwa okuphumelelayo kokufakwa kwe-insulation okuhlangabezana nezinhloso zakho zokonga amandla.

Kungakhathaliseki ukuthi ukhetha ukufaka i-foam yeseli evaliwe noma i-open-cell-cell, ungaqiniseka ukuthi utshala imali kusixazululo se-insulation sekhwalithi ephezulu, esihlala isikhathi eside esizothuthukisa ukunethezeka, ukuphepha, kanye nokusebenza kahle kwamandla kwekhaya lakho noma isakhiwo. Ngakho-ke, cabangela umehluko phakathi kwegwebu le-PU yeseli evaliwe neselivulekile bese ukhetha inketho evumelana kangcono nezidingo zakho zokufakwa ngaphakathi.
