Abathandi bemisebenzi yangaphandle emibhalweni yasensimini kufanele bathathe kanye nenani elikhulu lezinto, kusuka ezingutsheni kuya ezitsha. Ngokuyinhloko, kufanele unakekele indawo yakho yokulala kusengaphambili: lokhu, thatha itende kanye nesigqoko sokulala nawe . Kodwa akuyona into engathandeki ukuyibeka ngqo emhlabathini ukuze ugweme i-hypothermia. Ngokujwayelekile ngaphansi kwesigqoko sokulala umjaho okhethekile wokuvakasha ugxiliwe. Ngesikhathi esifanayo, akukhona nje amatshi amakhulu amakhulu okubhebhetheka esikhwameni sokulala, kodwa futhi amacu okuhlala ahlangene athengiswa.
Yenzani ama-rugs ezokuvakasha?
Izindwangu zokuvakasha zenziwe ngezinto ezihlukahlukene:
- i-polyethylene foam;
- i-polyurethane foam;
- i-microfiber;
- i-ethylene vinyl acetate.
I-inflatable tourist rug igcwele umoya. Kungenziwa kalula: noma ngepompe ehlukile (ibhukwana noma unyawo) noma ngomlomo. Noma kunjalo, inqubo enjalo ingathatha isikhathi eside kakhulu. Ukunciphisa umoya udinga ukuguqula umbhola wezokuvakasha ube yitayipi.
Ukungahambi kahle kwegumbi elingenakulinganiswa ukuthi kungaphezu kwalokho kudingekile ukuthatha ipompo, okuvame ukuthatha isikhala esiningi esikhwameni.
Kumele kukhunjulwe ukuthi ukusebenza kombhede ongathembeki kungase kukhishwe, ngakho-ke kuyadingeka ukuba ube nekithi yokulungisa nawe.
Enye ingozi ebalulekile yomkhiqizo wukuthi lapho izinga lokushisa eliphansi liyehla, ivolumu yomoya emaphepheni iyancipha. Ngakho-ke, uma ulisebenzisa ukulala ebusuku, kungase kudingekile ukuba uqale ukupompa umthamo ongathandekiyo ebusuku. Uma kungenjalo, ekuseni ungakwazi ukuvuka emgodini oboshiwe cishe olele ezweni elilodwa.
Amathebhu okuhamba ngamavama ngokuvamile ayenziwe nge-polyethylene foam. Inesakhiwo esihle sokushisa esishisayo. Le matti ine-strap elastic, engashintshwa ngamandla wezingqinamba nobude. Isihlalo sokuvakasha esinjalo sithathwa nabo emgwaqweni ngabalimi bezintaba, ama-kayakers, abadobi.
Okuthandwa kakhulu yizihambi zijabulela umbhoshongo wokuvakasha, obizwa ngokuthi i-foam ethandwa, eyenziwe nge-polyurethane foam. Ngenxa yobukhulu bayo obuhlanganisiwe kulula ukuyihambisa esimweni esisontekile, ukuyifaka emaceleni ohlangothini wesikhwama. Ngenxa yalokho, indawo ngaphakathi kwesikhwama igcinwa. I-foam mat inezinhlobo ezimbili:
- ukulayishwa okukodwa;
- i-two-layered (sonke-isizini).
Amashadi amabili angaphezu kwamanzi aphezulu futhi angapheli, angasetshenziswa ngisho nasezingeni eliphansi lokushisa. Ngenkathi umbhede owodwa ungakhelwe kuphela ngesimo sezulu esifudumele, awunamathela kancane futhi ungalimaza kakhulu. Umgudu wokuvakasha ohlotshiswe ngomfanekiso utholakala ngentengo engabizi, isisindo esincane. Kodwa-ke, kungabizwa ngokuthi umgudu wokusetshenziswa okukodwa, ngoba ngenxa yokusetshenziswa kwayo okusebenzayo ezimweni ezimbi zezulu, ifilimu ye-aluminium ingaqedwa.
Ukugcwaliswa komgudu wokuvakasha kungenziwa nge-microfiber. Lo mti unamagagasi amabili:
- ngenxa yentengo yalo;
- for deflation.
Ikati ngokuvamile ihamba nekhava elingenamanzi yomgudu wokuvakasha, ongasetshenziselwa futhi njengomlenze.
I-ethylene vinyl acetate (i-EVA) ayinalo kuphela izakhiwo zokushisa ezishisayo, kodwa futhi izici zanda ukuqina, ngaphandle kokulahlekelwa ukuma kwayo ngaphansi kwethonya lokushisa okuphansi. Le matti inezinamba eziningi zokungabikho:
- Isisindo esinzima: ezinye zithokozi zinesisindo esingaphezu kweyodwa;
- kwifomu elihlungwe likhulu;
- ngenxa yesenzo sezinga lokushisa eliphakeme (isibonelo, lapho kuvezwa ilanga isikhathi eside) kungase kufezeke.
Yimuphi umgudu wokuvakasha ongcono?
Okuthandwa kakhulu phakathi kwezokuvakasha kuyigumbi lokuvakasha elizimele, elenziwe nge-polyurethane. Iqukethe isisindo esincane nokulinganisa okulingene, ngenkathi igcina izindawo eziphezulu zokushisa okushisa. Njengoba igaxa ngokuzenzekelayo, kulula futhi kulula ukuyisebenzisa emvelweni.
Impendulo eyinhloko yalombhoyi i-valve epholile, engakapheli isikhathi.
Kanti futhi ukuhamba ngezinyawo kuyinto efanelekayo ukulandelela izivakashi mat, okuyinto unesisindo esikhulayo futhi ukugqoka, ithatha isikhala kancane futhi ine ukuthungela okuhle thermal.
Indlela yokukhetha umthamo wokuvakasha we-polyurethane ozithandayo?
Uma ukhetha ibhola, kufanele uqaphele imingcele elandelayo:
- isisindo;
- ukulinganisa;
- inani lezinto ezisetshenzisiwe (kwezinye izinhlobo, ungabona ngokushesha izingxenye ezimbili zama-isomaterials);
- Umbala: abanye abakhiqizi bakhiqiza amakhadi ikakhulukazi ezinganeni.
Umgudu wokuvakasha uyimfanelo ebalulekile yimuphi uhambo lokuhamba. Ngakho-ke, kufanele akhethwe ngokucophelela ngokucophelela.
