"Nezamerzayku" kwa Kutentha: ndemanga, mtengo. "Nezamerzayku" kachitidwe Kutentha

Zimachitika kuti ntchito madzi monga coolant sizingatheke. Zikatero, kupulumutsa abwera "nezamerzayku" kwa magetsi. Timadzi ali amafuna kuti zinthu opaleshoni. Iwo ali ndi makhalidwe kwambiri ya madzi, amene ayenera kuganizira pamene angagwiritse dongosolo magetsi.

kusankhidwa

Osati chinsinsi chimene mmodzi wa zigawo zikuluzikulu zofunika kwambiri za m'nyumba ndi dongosolo magetsi. Popanda thandizo la izo mungasinthe frosts amphamvu, amene dziko lathu si angwiro, ndipo ndithudi, m'nyengo yozizira si kawirikawiri. Komabe, ngakhale kuti mtima wa ogula chisanu, muyenera kupereka ena zodabwitsa pasadakhale. Ndipo, mwinamwake, ndi owopsa kwa iwo akhoza zii Kutentha dongosolo - osati kanthu kuti chikhalidwe ichi imatengedwa pangozi.

Pakuti zinthu Kutentha dongosolo mwadzidzidzi Kodi sizikumuonekera bwino. Nkofunika kudziwa kuti angagwe osati kukatentha nyumba chapakati, komanso kukatentha payekha. Pachifukwa ichi, pamene angagwiritse dongosolo lililonse, m'pofunika tione mmene zinthu za chitetezo zina.

Malinga ndi akatswiri, vuto ambiri m'nyumba ndi kulephera kwa kukatentha, ndipo monga ulamuliro, nthawi zonse zimachitika mosayembekezeka. Pofuna kupewa zodabwitsa zimenezi, komanso kuthetsa kulephera kwa dongosolo Kutentha ndi kuzirala ake wotsatira, akatswiri amalangiza ntchito zoletsa kuwuma madzimadzi.

kapangidwe

"Nezamerzayku" kwa Kutentha - yemweyo zoletsa kuwuma kapena zoletsa kuwuma. Chuma chachikulu cha kutentha-chonyamulira - Musatembenukire kutentha ndi adatchithisira mu ayezi. Choncho pali thickening wa zikuchokera utakhazikika. zoletsa kuwuma kachitidwe otoplnyh chopangidwa pa mfundo yomweyo. Mu dongosolo lake lili zotsatirazi:

• zinthu (zina), amene makhalidwe a zikuchokera;
• zinthu (zoletsa) pofuna kupewa dzimbiri;
• zoyambitsa yogwira chigawo;
• mowa (glycol) maziko.

Chofunika yogwira

Motero, "nezamerzayku" chifukwa Kutentha ndi mowa ndi zinthu. Ndi lokha glycol si zoipa, koma ena zina zingasokoneze thanzi. Monga akhoza kuchita ngati yogwira chigawo zoletsa kuwuma:

• Glycerin.
• Propylene glycol.
• Ethylene glycol.

ethylene glycol

Kutentha kutengerapo madzimadzi zochokera glycol ndi koletsedwa ntchito ku nyumba za anthu ndi kukhazikikamo. Zofooka chifukwa chakuti "nezamerzayku" poizoni kwambiri Kutentha ndi pokhudzana ndi khungu zingachititse amayaka. mpweya kapena madzi kuti ndisapalamule thupi ndi zotsatira zoipa kwambiri, kuphatikizapo imfa.

zoletsa kuwuma

Onse amene akudziwika otsika kalasi zoletsa kuwuma - zoletsa kuwuma makina, zomwe ndi nthawi zina anazitsanulira mwa dongosolo Kutentha - opangidwa ethylene m'Baibulo. Komabe, ngati pali kuthekera pang'ono kukhudzana anthu ndi ethylene glycol, ndi ntchito yake ayenera kuzipewa pa zifukwa zotsatirazi:

1. The boilers combi akupezeka Kusakaniza ndi madzi dera otentha.
2. Mwina kutayikira.
3. Mwina evaporation wa thanki kuwonjezeka lotseguka.

Musagwiritse ntchito ethylene glycol antifreezing madzi kachitidwe komwe chotenthetsera ntchito ngati awiri kukatentha.

propylene glycol

madzimadzi kutentha kutengerapo zochokera propylene glycol, kwathunthu sanali poizoni. Ndithudi, izi sizitanthauza kuti zikhoza kukhala woledzera, koma ngati inu mwangozi anagunda mu Mlingo kochepa kwa khungu, kapena ngakhale mkati, sadzakhala ndi matenda.

glycerol

Glycerin "nezamerzayku" kwa Kutentha (mtengo wotsika) anatsanulira pakati pa zaka mazana makumi awiri ndi lakhala likugwiritsidwa ntchito bwinobwino deti. Glycerin - mankhwala chonse, mosiyana ndi m'mbuyomo awiri, izo siziri matayala youma, koma abwezeretsa icho. Mu mawu ena, glyceric zochita madzimadzi pa mphira monga lubricant kubwezeretsa, chifukwa mulibe nkhawa mmene rubbers kusindikiza.

opanga mwachidule

Pakati ogula Russian, wotchuka kwambiri "nezamerzayku" chifukwa Kutentha nyumba zopangidwa monga:

• "Hot-65Eko Magazi".
• "Stugna-N"
• "Ofunda House".

Posankha zoletsa kuwuma zofunika kukumbukira kuti okhutira yake propylene glycol limasonyeza kuti madzi crystallization ndondomeko kukuchitika kutentha -60 ° C.

Nezamerzayku kwa Kutentha: mtengo ndi zizindikiro luso

Nsonga ndi ndemanga akatswiri

Kumene, madzi - "nezamerzayku" kwa Kutentha ali katundu osiyanasiyana, makhalidwe ndi mavoti ntchito Komabe, chikhalidwe yaikulu ndi kupanda propensity kwa yozizira koopsa. Zoletsa kuwuma zikuchokera kumatanthauza zinthu kutentha pa zomwe crystallization amapezeka. Kumene, ayenera kusankha m'munsi kutentha, amene Ndi mmene kwa zone anu nyengo.

Kutentha dongosolo mtundu Mzimuyo amene "nezamerzayku" adzakhala yoyenera kwambiri dongosolo kunyumba magetsi. Monga tanena antifreezes onse analengedwa ntchito zinthu zosiyanasiyana. The zikuchokera anyamula ethylene glycol ndi mankhwala oopsa choncho akhoza kugwiritsidwa ntchito mu kachitidwe Kutentha kwa chatsekedwa mtundu. Zoletsa kuwuma zochokera propylene glycol, malinga ndi akatswiri, ndi zochepa poizoni.

Zoletsa kuwuma thandizo kutalikitsa moyo utumiki wa dziko lonse Kutentha, kuphatikizapo radiators. Ndipo Chofunika, zimenezi coolant chindiletsa mpweya mapangidwe.

Zoletsa kuwuma - chisakanizo cha propylene glycol ndi Kuwonjezera zosiyanasiyana zigawo zikuluzikulu ochepetsera. Wapakati nthawi ya utumiki wa zoletsa kuwuma ndi zaka 4-5.

Pomaliza

Quality "nezamerzayku" kachitidwe Kutentha ayenera kupereka uyende dongosolo, ngakhale pangozi. Choncho, kuti apulumutse pa ogulidwa ndi zoletsa kuwuma zosayenera kwathunthu. Mungathe kusunga mwina pa diluting izo ndi madzi otchezedwa, koma choncho, ngati mulibe paniruete ntchito dongosolo Kutentha pansi kwambiri zinthu, mwachitsanzo, mu mbali kumpoto kwa dzikolo.
