Olee otú itughari antifreeze uche?

Kedu ihe bụ antifreeze concentrate?

Antifrize etinyere nwere naanị otu akụrụngwa na-efu: mmiri a na-ekpo ọkụ. Ihe ndị ọzọ niile (ethylene glycol, ihe mgbakwunye na agba) na-anọkarị n'uju.

A na-enwekarị mgbagwoju anya n'ụzọ na-ezighị ezi na ethylene glycol dị ọcha. Ụfọdụ ndị na-emepụta ihe na-egosi na nkwakọ ngwaahịa na e nwere naanị ethylene glycol n'ime. Agbanyeghị, nke a enweghị ike ịbụ eziokwu naanị n'ihi na ethylene glycol bụ mmiri mmiri na-enweghị agba. Na ihe fọrọ nke nta ka ọ bụrụ ihe niile etinyere na-acha agba dịka akara klaasị anabatara (G11 - green, G12 - red or yellow, wdg).

N'oge gara aga, ntụ oyi oyi na-enweghị ụcha dị na ahịa. Ma eleghị anya, ha ji ezigbo ethylene glycol mee ihe. Otú ọ dị, ọ bụ ihe na-adịghị mma iji ntinye uche dị otú ahụ maka nkwadebe nke coolant dị elu. N'ezie, na-enweghị ihe mgbakwunye, metal corrosion na mbibi nke ọkpọkọ rọba ga-abawanye ngwa ngwa. Na ndị a mejupụtara bụ naanị adabara ime ka ala-okpomọkụ Njirimara nke ugbua wụsara antifreeze.

Nke mbụ, ka anyị chọpụta kpọmkwem otu esi ejikọta uche na mmiri ka ị ghara ịwụpụ ihe mejupụtara ya ma emechaa.

1. Usoro nke ihe ị ga-etinye n'ime ya adịghị mkpa. Yana akpa nke ngwakọta ga-eme. Ọ dị mkpa idobe oke.
2. Wunye mmiri n'ime tankị mgbasawanye mbụ, wee tinye uche, n'ọnọdụ ụfọdụ ọ ga-ekwe omume, ma ọ dịghị mma. Nke mbụ, ọ bụrụ na ị na-akwadebe antifreeze ozugbo maka nnọchi zuru oke, mgbe ahụ ego ị gbakọrọ nwere ike ọ gaghị ezuru. Ma ọ bụ, n'aka nke ọzọ, ị ga-enweta ọtụtụ antifirizi. Dịka ọmụmaatụ, ị buru ụzọ wụsa lita 3 nke itinye uche, wee mee atụmatụ ịgbakwunye 3 lita mmiri. N'ihi na ha maara na ngụkọta olu nke coolant na usoro bụ 6 lita. Otú ọ dị, 3 lita nke itinye uche dabara n'enweghị nsogbu, na naanị 2,5 lita mmiri banyere. N'ihi na a ka nwere ihe mgbochi ochie na usoro ahụ, ma ọ bụ na e nwere radiator na-abụghị ọkọlọtọ, ma ọ bụ na e nwere ihe ọzọ kpatara ya. Na n'oge oyi, na okpomọkụ n'okpuru -13 Celsius C, a na-amachibido iwu iji mejupụta mmiri mmiri iche iche. Paradoxical, ma eziokwu: dị ọcha ethylene glycol (yana antifreeze concentrate) freezes na -13 Celsius.
3. Etinyekwala uche site n'otu coolant gaa na nke ọzọ. Enwere oge mgbe, n'oge ngwakọta dị otú ahụ, ụfọdụ n'ime ihe mgbakwunye ahụ na-agbarịta ụka ma malite.

Enwere oke ngwakọta atọ maka coolants:

• 1 ruo 1 - a na-enweta antifirizi nke nwere ebe na-ekpo ọkụ nke ihe dịka -35 Celsius C na ntinye;
• 40% itinye uche, 60% mmiri - ị ga-enweta coolant nke na-adịghị ifriizi ihe dị ka -25 Celsius C;
• 60% itinye uche, 40% mmiri - antifirizi nke ga-anagide okpomọkụ ruo -55 Celsius.

Iji mepụta antifrize na ihe ndị ọzọ na-ekpo ọkụ, e nwere tebụl dị n'okpuru ebe a na-egosi nnukwu ngwakọta nke nwere ike ime.
