Foshan materase fektheri lokela ho utloisisa latelang 5 melao-motheo ea ha a khetha materase

Mongoli: Synwin– Moetsi oa Materase

Khetha materase lokela ho utloisisa latelang 5 melao-motheo ea. (1) Sheba lintlha tsa sehlahisoa Letšoao la semmuso la sehlahisoa le na le lebitso la sehlahisoa, lets'oao le ngolisitsoeng, lebitso la khamphani kapa moetsi, aterese ea feme, nomoro ea mohala kapa fekse, hape e na le setifikeiti sa tumellano le karete ea mokoloto. Botumo bo botle ba brand ke tiisetso ea boleng ba materase.

(2) Sheba boima. Boemong ba ho robala le ho robala ka lehlakore, hlahloba hore na ho na le likheo pakeng tsa molala, letheka le letheka ho ea liropeng le pakeng tsa ho kobeha ha 'mele le materase. Haeba ho se na lekhalo, ho paka hore materase a amana le molala oa motho. , Likhahla tsa tlhaho tsa mokokotlo, letheka, letheka le maoto li tsitsitse haholo 'me li le bonolo ebile li le thata. Ho phaella moo, o lokela ho nahana ka phapang pakeng tsa bolelele le boima ba 'mele. Batho ba bobebe ba robala libetheng tse bonolo, mahetla le letheka li kenngoe hanyane ka har'a materase, 'me mokokotlo o tlase o tšehelitsoe ka botlalo.

Boima bo boima bo loketse ho robala holim'a materase a thata. Matla a thepa ea materase a lokela ho etsa hore karolo e 'ngoe le e' ngoe ea 'mele e ikutloe e phutholohile, haholo-holo molala le letheka li lokela ho tšehetsoa hantle. (3) Sheba elasticity E le hore u tsebe hore na elasticity ea materase e ntle, u ka sebelisa mangole ho hlahloba holim'a bethe, kapa u lule fatše k'honeng ea bethe ho bona hore na materase a hatelitsoeng a ka khutlela ka potlako sebopeho sa eona sa pele. Bethe e ntle e nang le elasticity e ntle Thepa e ka khutlisetsoa boemong ba eona ba pele hang ka mor'a ho hatelloa. (4) Ho itšetlehile ka thepa, ho ea ka boemo ba leholimo ba sebaka seo, khetha sebaka se loketseng sa moea, conductivity ea mocheso le materase a nang le mongobo.

Tsela e ka tšeptjoang ea ho khetholla thepa ke ho robala le ho thinyetsa ka ho le letšehali le ka ho le letona ho bona hore na materase a na le molumo o sa tloaelehang, ho se leka-lekane, ho sisinyeha ha bohale le ho sisinyeha ha lesela. (5) Botenya ba materase bo lokela ho ba 18-23 c, ho itšetlehile ka ponahalo. Botenya bona bo ke ke ba fana ka tšehetso e ntle feela, empa hape le ho boloka phefumoloho e ntle.
