Igwebu Lokuvikela Lokuvikela Isitoreji Sezibhamu Nokuthumela

Ukugcinwa kwesibhamu okusebenzayo nokuthunyelwa kuncike ezintweni ezimbili ezibalulekile: ukukhetha okubalulekile okuyigwebu nokumatanisa nekesi langaphandle eliqinile. Zombili izingxenye zidlala indima ebalulekile ekuvikelweni futhi zingenziwa ngendlela oyifisayo ukuze kuthuthukiswe ukuphepha ngesikhathi sokulondoloza nezokuthutha.

Ukukhetha igwebu elifanele icala lesibhamu kuncike ekutheni icala lizosetshenziswa kanjani—kungaba elokugcina isikhathi eside, ezokuthutha, noma kokubili. Lapho uhlola izinketho zegwebu, kubalulekile ukucabangela ukuvikelwa komthelela osheshayo kuphela kodwa nokulondolozwa kwesikhathi eside ukuze kuqinisekiswe ukuthi isibhamu sihlala sivikelekile futhi sivikelekile ngokuhamba kwesikhathi.

Izinketho Zegwebu Zamacala Ezibhamu

Izinto ezimbili eziyinhloko zegwebu zivame ukusetshenziswa emacaleni ezibhamu ukuze zithunyelwe futhi zigcinwe: i-polyurethane ne-polyethylene.

I-Polyurethane iyigwebu elithambile, elivulekile-cell elaziwa ngokuhle kakhulu ukumunca nokumunca ukushaqeka. Kulula ukwenza nokusika ngokwezifiso, okuvumela ukulingana okunembile ngaphakathi kwamakesi ezibhamu aklanyelwe. I-Ester-based polyurethane ivame ukuthandwa ngenxa yamandla ayo aqinile aqinile kanye nendawo engaqhumi, esiza ukuvikela ukuphela kwesibhamu ngesikhathi sokuthutha.

Kodwa-ke, i-polyurethane-ikakhulukazi izinhlobo ezisekelwe ester-ingawohloka ngokuhamba kwesikhathi. Isengozini enkulu yomswakama, uwoyela, izinto zokuthambisa, nezihlanzi zamakhemikhali ezivame ukusetshenziswa ekulungiseni izibhamu. Ngenxa yalokhu, igwebu le-polyurethane ngokuvamile lifaneleka kangcono ukuthunyelwa kwemikhumbi yesikhashana kunokugcina izibhamu zesikhathi eside.

I-polyethylene, ngokuphambene, i-foam-cell evaliwe enesakhiwo esiqinile. Inikeza ukumelana okuqinile kumswakama noketshezi, okwenza kube ukukhetha okuhlala isikhathi eside ukuze kugcinwe isikhathi eside. Igwebu le-polyethylene alibhiliki kalula lapho livezwa amafutha noma izinto zokuhlanza futhi linikeza ukumelana namabala okuphakeme uma kuqhathaniswa ne-polyurethane. Ukuqina kwayo okuphezulu nakho kuyenza ikufanelekele ukusekela izibhamu ezinzima emakesini afakwe ngokwezifiso.

Igwebu Elihlanganisiwe

Amashidi e-polyfoam ahlanganisiwe—ngokuvamile aziwa ngokuthi i-egg-crate foam—ayizinto ezithambile, ezinamaseli avulekile avame ukusetshenziselwa ukuvala izivalo zamakesi ezibhamu. Indawo yazo ebhaliwe isiza ukugudluza kanye nokuzinzisa okuqukethwe ngesikhathi sokulondoloza nokuhamba.

Igwebu elihlanganisiwe liyinketho esebenzayo yakho kokubili ukuthunyelwa nokugcinwa, ikakhulukazi uma ikesi lihloselwe ukuphatha izinhlobo ezahlukene zezibhamu. Nakuba izimo eziningi zokwenza ngokwezifiso zifaka okufakwayo okusikwe ngokunemba okudizayinelwe isibhamu esithile kanye nezingxenye zaso, le ndlela ikhawulela ikesi ekucushweni okukodwa. Ngokuphambene, igwebu elihlanganisiwe linikeza ukwesekwa okuvumelana nezimo ngaphandle kokusikwa ngokwezifiso, okuvumela ikesi elifanayo ukuthi lifake izibhamu ezihlukahlukene njengoba kudingeka.
