Enwere ike ịgwakọta antifirizi G11 na G12?

Antifrize G11 na G12. Kedu ihe dị iche?

A na-eme ka ọnụ ọgụgụ ka ukwuu nke coolants (coolants) maka ụgbọ ala ndị nkịtị na-adabere na mmanya dihydric, ethylene ma ọ bụ propylene glycols, na mmiri distilled. Mmiri na mmanya na-eme ka ihe karịrị 90% nke mkpochapụ. Ọzọkwa, oke nke ihe abụọ a nwere ike ịdịgasị iche dabere na okpomọkụ oyi chọrọ nke coolant. Ihe mgbakwunye na-eji ihe ndị fọdụrụ na antifirizi.

G11 antifreeze, dị ka ihe fọrọ nke nta ka ọ bụrụ ụlọ obibi Tosol zuru ezu, nwekwara ethylene glycol na mmiri. Ihe mgbochi ndị a na-eji ogige inorganic, phosphates dị iche iche, borates, silicates na ihe ndị ọzọ dị ka ihe mgbakwunye. Ogige inorganic na-eme n'ihu usoro: n'ime awa ole na ole mgbe ejuputa na usoro ahụ, ha na-emepụta ihe nkiri nchebe na mgbidi nke sekit niile jụrụ oyi. Ihe nkiri ahụ na-ewepụ mmetụta ike nke mmanya na mmiri. Otú ọ dị, n'ihi oyi akwa ọzọ dị n'etiti jaket jụrụ oyi na oyi na-ekpo ọkụ, nkwụsị ọkụ na-ebelata. Ọzọkwa, ndụ ọrụ nke klas G11 antifreezes na inorganic mgbakwunye bụ mkpụmkpụ na nkezi 3 afọ maka àgwà ngwaahịa.

A na-emepụta ọgwụ mgbochi G12 site na ngwakọta nke mmiri na ethylene glycol. Otú ọ dị, ihe mgbakwunye na ya bụ organic. Ya bụ, isi ihe na-echebe megide ethylene glycol aggression na G12 antifreeze bụ carboxylic acid. Ihe mgbakwunye carboxylate Organic anaghị etolite ihe nkiri dị n'otu, nke mere na ike nke iwepụ okpomọkụ adịghị ada. Ngwakọta Carboxylate na-eme ihe ziri ezi, naanị na saịtị corrosion ka ha pụtachara. Nke a na-ebelata ntakịrị ihe nchebe, ma ọ dịghị emetụta thermodynamic Njirimara nke mmiri mmiri. N'otu oge ahụ, antifreezes dị otú ahụ na-eje ozi maka ihe dị ka afọ 5.

G12+ na G12++ antifreezes nwere ihe mgbakwunye organic na inorganic. N'otu oge ahụ, enwere ihe mgbakwunye inorganic ole na ole na-emepụta oyi akwa na-ekpo ọkụ na oyi ndị a. Ya mere, G12 + na G12 ++ antifreezes anaghị egbochi ikpochapụ okpomọkụ ma n'otu oge ahụ nwere ogo abụọ nke nchebe.

Enwere ike ịgwakọta antifreezes G11 na G12?

Ị nwere ike ịgwakọta G11 na G12 antifreezes na atọ.

1. Kama G11 antifreeze akwadoro, ị nwere ike jupụta n'efu na klaasị G12 ++, yana ịgwakọta coolants abụọ a n'ụzọ ọ bụla. Antifreeze G12 ++ bụ ihe zuru ụwa ọnụ, ma ọ bụrụ na ọ na-agbanwe ụdị ọrụ nke usoro jụrụ oyi, ọ bụ ihe na-abaghị uru. N'otu oge ahụ, ihe nchebe nke klas nke coolant a dị elu, na ngwugwu mgbakwunye bara ụba ga-echebekwa usoro ọ bụla site na corrosion.
2. Kama G11 antifreeze, ị nwere ike dejupụta G12 + maka otu ihe ahụ akọwara na paragraf mbụ. Otú ọ dị, na nke a, enwere ike inwe ntakịrị mbelata na akụrụngwa nke ihe ndị dị n'otu n'otu nke sistemu igwe jụrụ oyi.
3. Ị nwere ike ịgbakwunye ibe gị n'enweghị nsogbu na obere nha, ruo 10%, ụdị antifreeze G11 na G12 (gụnyere mgbanwe ha niile). Nke bụ eziokwu bụ na ihe mgbakwunye nke coolants ndị a adịghị agbaji ma ghara ịgbasa n'oge mkparịta ụka, ma ọ bụ naanị na ọnọdụ na mmiri mmiri dị na mbụ nke dị elu ma mee ya dịka ụkpụrụ.

A na-ahapụ ya, mana akwadoghị ya, ka ọ jupụta na klaasị G11 coolant kama G12 antifrize. Enweghị ihe mgbakwunye inorganic nwere ike ibelata nchebe nke ihe ndị na-emepụta roba na ígwè ma belata ndụ nke ihe ndị dị n'otu n'otu nke usoro ahụ.

Ọ gaghị ekwe omume imeju klaasị coolant G12 yana G11 antifreeze achọrọ. Nke a ga-emetụta mmetụta na-adịghị mma nke ikpo ọkụ ọkụ na ọbụna nwere ike iduga na-esi ísì nke moto.
