Zoletsa kuwuma ofiira ndi maganizo ena

Zoletsa kuwuma ndi madzi amene yozizira koopsa m'munsi kutentha kuposa crystallization kutentha kwa madzi. Kugwiritsa ntchito madzi zimathandiza kuteteza zimagwirira kumene kungachitike pamene H2O crystallization. Zoletsa kuwuma (wofiira, wachikasu, zobiriwira, etc.) Amakhala ndi madzi ndipo ndi mowa polyhydric. Komanso, coolant anawonjezera zina zosiyanasiyana, dzimbiri zosagwira zigawo zikuluzikulu monga bwino. Izi mankhwala zina zimathandiza kuti mwatsatanetsatane chitetezo. Monga mbali ya madzimadzi mulinso utoto, lomwe kuwapatsa mtundu makamaka. Malinga ndi ndemanga a akatswiri a mtundu madzi alibe mphamvu pa ntchito yake. Malinga ndi kuchuluka, zoletsa kuwuma (wofiira ndi mitundu inayo) Mwina amapanga ethylene glycol kapena propylene glycol.

Yotsirizira ndi colorless viscous wochuluka madzi. Iwo ali ndi khalidwe kukomoka fungo. Ethylene glycol ndi poizoni yolimba, samalani pamene muzizigwiritsa. Koyera ethylene glycol atapanga pa madigiri opanda khumi ndi zitatu. kuwira mfundo zake ndi madigiri 197. Izo ziyenera ananena kuti ethylene glycol mu moyikirapo amadzimadzi njira amaundana pa kutentha otsika (ngati ntchito magawo awiri a ethylene glycol ndi gawo limodzi madzi). Otentha mfundo zoletsa kuwuma pa avareji za zana makumi awiri madigiri, ndi osachepera mfundo zake yozizira koopsa mwina madigiri makumi asanu ndi awiri pansi pa ziro. Monga ulamuliro, zoletsa kuwuma (wofiira, wachikasu, etc.) lili mu kapangidwe kake za 50-60% ethylene glycol. Pankhaniyi, ndi wofanana ndi osachepera yozizira koopsa kutentha kwa madigiri makumi atatu pansi pa ziro.

Mu kupanga zoletsa kuwuma kumakhalanso nthawi zambiri ntchito propylene glycol. Nkhanizi ndi zambiri zachilengedwe wochezeka. Pankhaniyi, ntchito ndi pafupifupi palokha maziko a. Komabe, propylene glycol ndi otetezeka ndi zochepa poizoni.

mawu "odana ndi amaundana" akhoza kwenikweni ndimene "odana ndi chisanu" kapena "ayezi". Mawu amenewa amagwiritsidwa ntchito ponena kuti zopangidwa onse coolants.

Zoletsa kuwuma kapena zoletsa kuwuma - umene uli bwino?

Tikumbukenso kumayambiriro kuti mfundo yoyamba amagwiritsidwa ntchito ponena kuti madzi kupanga zoweta. Mawu akuti "zoletsa kuwuma" lili dzina la khadi, umene udaikidwa (Organic kaphatikizidwe matekinoloje Division (CBT)). Mapeto "ol" amatanthauza mfundo za thupi mowa. Zoletsa kuwuma amatanthauza coolants mwambo kuti posachedwapa ndipo kawirikawiri kwambiri ntchito.

Monga tanenera kale, ntchito katundu wa zinthu alibe zimadalira izi ndi zoletsa kuwuma - wofiira, buluu, chikasu kapena zambiri za mtundu uliwonse. Poyamba, zakumwa onse ali wa mtundu womwewo. Zoletsa kuwuma utoto anati zina "umunthu." Akukhulupirira kuti analola kusanganikirana madzi a mtundu womwewo kwa wina ndi mzake. Tikumbukenso kuti wonyenga zinthu zambiri. The ma CD a zoletsa kuwuma wopanga nthawi zonse amapereka malangizo kwa mphamvu kusakanikirana mtundu wake ndi ena.

Pa nthawi yomweyo wina boma muyezo wakhala zithandize madzi zoweta. Izo ziyenera Komabe, kudziŵika kuti motsata mtheradi wa GOST sizitanthauza makhalidwe awo apamwamba. Mwachitsanzo, zoletsa kuwuma Russian kupanga si nthawi zonse ntchito mapangidwe yamakono ya injini. Mu nkhani iyi, European odana ndi amaundana si zogwirizana ndi Russian muyezo, kusonyeza mkulu khalidwe ntchito.
