"Nezamerzayku" Ukushisa: ukubuyekezwa, intengo. "Nezamerzayku" Ukushisa izinhlelo
Kwenzeka ukuthi ukusetshenziswa kwamanzi njengoba kokupholisayo akunakwenzeka. Ezimweni ezinjalo, wangisiza iza "nezamerzayku" for bafudumale. Lolu ketshezi anezinye izimfuneko nemibandela yokusebenza. It has izici kakhulu yamanzi futhi kudingeka kubhekwe lapho ukuklama uhlelo bafudumale.
aphoyintimenti
Akukho imfihlo ukuthi kwenye yezingxenye ezibaluleke kakhulu emzini womzalwane kuyinto uhlelo Ukushisa. Kuyinto kuphela ngosizo ke ungadlulisa yesithwathwa eqinile, kusukela lapho ezweni lethu aluphelele, futhi ngempela, ebusika akuyona ezingavamile. Nokho, naphezu ukuzimisela abathengi ngenyanga, kufanele unikezele ezinye lezimanga kusengaphambili. Futhi, mhlawumbe, ayingozi kakhulu babo kungenziwa simisiwe bafudumale system - lutho kulesi simo kubhekwa esiphuthumayo.
Ukuze Ukushisa uhlelo isimo esiphuthumayo akubikezeli. Kubalulekile ukwazi ukuthi lesi kungenzeka hhayi kuphela e kubhayela endlini eyodwa, kodwa futhi kubhayela ngabanye. Ngenxa yalesi sizathu, lapho ukuklama yiluphi uhlelo, kubalulekile ukuba sicabangele izimo sokuphepha ezengeziwe.
Ngokusho kochwepheshe, inkinga ezivamile owawusemzini womzalwane kuyinto ukwehluleka kubhayela, futhi, njengoba umthetho, njalo kwenzeka kungalindelekile. Ukuvimbela lezimanga enjalo, kanye ukuqeda ukwehluleka bafudumale system kanye nokupholisa kwalo okwalandela, ochwepheshe ukweluleka ukusebenzisa emelana nokubanda enhlanzini yasezindaweni uketshezi.
isakhiwo
"Nezamerzayku" Ukushisa - okufanayo emelana nokubanda enhlanzini yasezindaweni noma emelana nokubanda enhlanzini yasezindaweni. Impahla main yokushisa-yenethiwekhi - angabuyeli izinga lokushisa lehliselwa eqhweni. Ngakho kukhona ukuqina Ukwakheka selehlile. Noma yimuphi emelana nokubanda enhlanzini yasezindaweni izinhlelo otoplnyh ekhiqizwa ku isimiso esifanayo. Ngo oyiyo iqukethe okulandelayo:
- izinto (izithasiselo), obangela izici Ukwakheka;
- izinto (inhibitor) yokuvimbela ukugqwala;
- ingxenye eyinhloko esebenzayo;
- utshwala (glycol) isisekelo.
Isithako asebenzayo
Ngakho, "nezamerzayku" Ukushisa kanye utshwala kuyinto into. Ngu uqobo, glycol ayiyona ingozi, kodwa abanye izithasiselo ungakulimaza impilo. Njengoba ingaba njengesihluthulelo ikhomponethi asebenzayo emelana nokubanda enhlanzini yasezindaweni:
- Glycerin.
- Propylene glycol.
- Ethylene glycol.
Ethylene glycol
ukudluliselwa Heat uketshezi esekelwe glycol akuvunyelwe nakancane ukusebenzisa emakhaya abantu nge zokuhlala unomphela. Ukulinganiselwa ngenxa yokuthi lokhu "nezamerzayku" enobuthi kakhulu for Ukushisa kanye nabo isikhumba kungabangela ukusha. Igesi noma uketshezi angene emzimbeni kungaholela emiphumeleni engathí sina, kuhlanganise nokufa.
emelana nokubanda enhlanzini yasezindaweni
Zonke ezaziwayo ongaphakeme-ebangeni emelana nokubanda enhlanzini yasezindaweni - emelana nokubanda enhlanzini yasezindaweni umshini, okuyinto ngezinye izikhathi futhi batheleka bafudumale system - ethylene ekhiqizwa based. Nokho, uma kukhona kungenzeka kancane contact womuntu ethylene glycol, ivela ngokusetshenziswa kwayo kufanele kugwenywe ngenxa yezizathu eziningana:
- I boilers combi kwenzeka ukuxuba ne esishisayo namanzi supply wesifunda.
- Angase avuze.
- Mhlawumbe ukuhwamuka we ukunwetshwa ithangi evulekile.
Ungayisebenzisi ethylene glycol antifreezing uketshezi izinhlelo lapho heater isetshenziswa njengophawu kabili kubhayela.
propylene glycol
ukudluliselwa Heat uketshezi esekelwe propylene glycol, ngokuphelele non-enobuthi. Yiqiniso, lokhu akusho ukuthi kungaba odakiwe, kodwa uma ngephutha hit ngemithamo okuncane esikhumbeni, noma ngisho ngaphakathi, ngeke babe nezinkinga zempilo.
glycerol
Glycerin "nezamerzayku" Ukushisa (ngentengo ephansi) wathela kusukela phakathi kwekhulu lamashumi amabili futhi iye yasetshenziswa ngempumelelo kuze kube manje. Glycerin - ikhambi jikelele, futhi ngokungafani odlule ezimbili, kungaqali amathayi ezomile, kodwa kunalokho ubuyisela ke. Ngamanye amazwi, lo glyceric izenzo unamanzi irabha uwoyela nokubuyisela, okuholela asikho isidingo sokuthi bakhathazeke mayelana nesimo rubbers uphawu.
Uhlolojikelele abakhiqizi
Phakathi abathengi isiRashiya, ethandwa kakhulu "nezamerzayku" for amalahle brand indlu njenge:
- "Zezıhlabane-65Eko Igazi".
- "Stugna-N"
- "Indlu Warm".
Uma ukhetha emelana nokubanda enhlanzini yasezindaweni kubalulekile ukukhumbula ukuthi okuqukethwe yayo propylene glycol ibonisa ukuthi uketshezi crystallization nqubo ithatha indawo ezingeni lokushisa -60 ° C.

Amathiphu amazwana kusukela ochwepheshe
Yiqiniso, uketshezi - Nokho, "nezamerzayku" Ukushisa has properties ahlukahlukene, izici nezilinganiso isicelo, isimo eyinhloko yokuntuleka propensity kuya okokuqandisa. Emelana nokubanda enhlanzini yasezindaweni Ukwakheka kuchazwa izimo lokushisa lapho crystallization kwenzeka. Yiqiniso, kufanele ukhethe lokushisa ephansi, okuyinto ejwayelekile lakho zone sezulu.
bafudumale system uhlobo ubheka ukuthi yiziphi "nezamerzayku" kungaba efaneleka kakhulu ohlelweni ekhaya bafudumale. Njengoba kushiwo ngenhla, zonke antifreezes zidalwe usebenzisa izinto ezihlukahlukene. Ukwakheka ingaqukatha ethylene glycol kuyinto into enobuthi, ngakho-ke kungasetshenziswa kuphela e Ukushisa izinhlelo ohlobo avaliwe.

Emelana nokubanda enhlanzini yasezindaweni usizo ukunweba ukuphila inkonzo yonke bafudumale system, kuhlanganise radiators. Futhi okubaluleke nakakhulu, ukuthi kokupholisayo kuvimbela igesi kumiswa.
Emelana nokubanda enhlanzini yasezindaweni - inhlanganisela propylene glycol ne ukwengeza izingxenye ezihlukahlukene inhibitory. Isikhathi isilinganiso inkonzo emelana nokubanda enhlanzini yasezindaweni uneminyaka engu 4-5.
isiphetho
Quality "nezamerzayku" Ukushisa izinhlelo kufanele ahlinzeke ekusebenzeni uhlelo, ngisho nasezimweni eziphuthumayo. Ngakho-ke, ukuze ulondoloze ku ukuthengwa emelana nokubanda enhlanzini yasezindaweni okungalungile ngokuphelele. Ungagcina mhlawumbe ukuthi diluting it ngamanzi distilled, kodwa kuphela ukuthi kunjalo, uma ungenawo paniruete ukusebenza uhlelo Ukushisa ngaphansi kwezimo ezimbi kakhulu, isibonelo, izingxenye enyakatho yezwe.
