Kwenzekani Lapho Isihlalo Sihlangana Nobuchwepheshe Be-Vacuum — Ubunjiniyela Bezinto Zokwakha Obusekelwe Ezihlalo Ezicindezelweyo

Izithengi eziningi zezihlalo azicabangi nge-chemistry ye-foam lapho zithenga isofa. Kodwa kubakhiqizi bezihlalo ezicindezelwe, i-foam density ayiyona imininingwane - kuyimibuzo ebalulekile. Ukucindezela isofa eyenziwe nge-foam formulation engalungile, izofika emnyango weklayenti ibukeka njengebhaluni eliphumputhukile.

Ubuchwepheshe obenza ukucindezela kube nokwenzeka akuyona i-vacuum pump uqobo. Kuyi-high-resilience (HR) polyurethane foam engamelana nokucindezelwa cishe kwesihlanu somthamo wayo wokuqala futhi isalokhu ibuyisa isimo sayo esiklanyelwe phakathi namahora angu-24-48 ngemuva kokukhipha.Abakhiqizi abahamba phambili bacacisa i-foam density phakathi kuka-30 no-50 kg/m³. Ngaphansi kwalo mkhawulo, ukusebenza kokubuyela emuva kuyadegrad. Ngaphezu kwawo, i-foam iba nzima ukucindezela ngokulinganayo, idale ukwehluleka kokupakisha.

Inqubo yokucindezela nge-vacuum iyahlukahluka ngokwekhono lomkhiqizi. Abanye basebenzisa imishini yokugoqa ehlanganisa isofa ibe yindilinga eqinile ngaphambi kokuyivala. Abanye basebenzisa izinhlelo zokucindezela ezicaba ezinefilimu ye-PE — i-polyethylene sheeting enikeza amandla okudonsa ukubamba izilinganiso zokucindezela zokunciphisa ivolumu ngo-50–70% ngaphandle kokudabuka ngesikhathi sokuthunyelwa.Ikhwalithi yefilimu ibaluleke kakhulu. Ifilimu ye-PE esezingeni eliphansi iyadabuka ngaphansi kokucindezela okuqhubekayo okuvela ngaphandle kwe-foam ekhulayo, ikakhulukazi ezimweni zokuthumela ezimanzi. Ukubeka uphawu okumelana nomswakama kanye nemiyalelo yokubuyisa okufakwe ekuphaketheni kuyizidingo ezingezansi kunoma yimuphi umphakeli othumela kwamanye amazwe.

Kunokushintshana okungaxoxwa kakhulu ngakho: ukuthungwa kwendwangu. Ukucindezela kungashiya imibimbi ezintweni ezithile zokuhlala, ikakhulukazi izindwangu eziqinile nezikhumba ezingezona ezangempela ezisezingeni eliphansi. Amafektri alawula lokhu kahle asebenzisa izinqubo zokwelapha izindwangu ngaphambi kwesikhathi nezinqubo zokucindezela ezilawulwayo. Lezo ezingakwenzi zithola ukubuyiswa. Kubathengi bangaphandle, lokhu kusho ukuqinisekisa izitifiketi ze-foam — i-ISO 9001 ne-BSCI ziyizimpawu eziyisisekelo — nokucela izibonelo zamavidiyo okubuyiselwa kokucindezela ngaphambi kokuzibophezela ekukhiqizeni.
