Girofu inzvimbo inoshandiswa yechando. Asi pane mamwe mazuva kune mazaya akadaro zvokuti kunyange mitsva inotonhora haina kuchengetedza maoko edu kubva kunotonhora. Ndicho chikonzero chigadzirwa chacho chakasikwa, chakadai sechanza chinopisa. Nezvayo, tichataura. Warmer is of two types - petrol and salt. Rudzi rwekupedzisira runowanzoshandiswa muupenyu hwezuva nezuva, somuenzaniso, nekumirira kwemarefu kwekutakura kwevanhu panzvimbo. Asi rimwe remhepo rinopisa moto rinowanzodiwa mumamiriro ezvinhu akaipisisa, kufamba-famba uye kubata hove.
Ruoko Dzokugadzirisa Ruoko
Kunze kwekunze, munyu wechuru ndiwo mutsara wemhando dzakasiyana-siyana (nyeredzi, crescent, moyo, rectangle, nezvimwewo), mukati maro mune geri-semvura yakasvikika uye shingairi shingaira. Nheyo yekushanda kwechigadzirwa chakadai chechigadzirwa chechigadziro chinochengetedzwa chinobva pamagumisiro ekudziya kwechiedza pane kristalllization ye salts ye-supersaturated solutions, kazhinji kacho sterodium acetate. Kana tikakotamisa muchengeti, sarudzo mu pad inotanga kumira. Muchiitiko ichi, kupisa kunosunungurwa, uye kupisa padhi pachayo kunopisa kunotonhora kunopfuura 50 ° C kwemaawa matatu kusvika mana. Mushure mekushandisa, iyo inopisa inofanira kuderedzwa mumvura inotonhora kwemaminitsi gumi nemashanu, ndokubviswa, yakaomeswa uye zvakare kushandiswa.
Sezvaunogona kuona, zvakakosha zvikuru zvemunyu zvinopisa zvinopisa zvinosanganisira nyore uye kugadzirisa zvakare kushandiswa, pamwe nekudhura.
Petrol hand warmer
Gasoline, kana kuti chinokanganisa, bhodhoro remvura inotonhora rinoyeuchidza kuonekwa kwaro senyaya yefodya ine simbi yesimbi yakakura yefoni. Chinhu ichocho chinosanganisira:
- tangi, iyo inofanira kuzadzwa nehupfumi (kazhinji kacho yekotoni) yakabatanidzwa nezvinhu zvinopisa (kazhinji mafuta);
- mesh chinokonzera kubva pakateti;
- yakagadzirirwa pamusoro pevhavha nehombodo.
Nheyo ye petroolin heater inobva pakusunungurwa kwehuni panguva yekusvibiswa kweporosi yemhepo inenge isingafadzi. Kutengesa miti inopinda mumakomba evhavha uye inopisa maoko ako. Tanga iyo inoshandisa moto inotonhora nekutsvaira chinokonzera kwemasekondi gumi neminomwe nemurazvo wechiedza kana gasi rinopisa. Kuti udzidzire maoko mazaya anodikanwa, apfeka moto unopisa chifukidzo chairo nekuda kwechingave chisina kupisa. Pakati pezvigadzirwa zvakabudiswa, Zippo ruoko rwunotonhora, chitubu chakakurumbira cheAmerica, nekunzwisiswa kwehutano uye kuchengetedzwa kunonyanya kuve pachena. Uyewo chigadzirwa chikuru chekudziya maoko uye Korean Kovea yakasimba.
Izvo zvakakosha zveuyu rudzi rwehuni-mvura inopisa dzinosanganisira nguva yebasa (kusvika maawa makumi maviri nemaviri) uye kukwanisa kwebasa (kwete maoko chete anotonhora).
