Ngwakọta kemịkalụ nke antifreezes g11, g12, g13
Ngwakọta akụrụngwa
Ndabere nke coolants (coolants) bụ distilled mmiri weere na mono- na polyhydric alcohols dị iche iche n'ike-n'ike. A na-ewebatakwa ihe mgbochi corrosion na ihe mgbakwunye fluorescent (ede) na ntinye uche. A na-eji Ethylene glycol, propylene glycol ma ọ bụ glycerin (ruo 20%) mee ihe dị ka mmanya mmanya.
- mmiri distillate
A na-eji mmiri dị nro mee ihe dị ọcha. Ma ọ bụghị ya, ọnụ ọgụgụ n'ụdị carbonate na phosphate nkwụnye ego ga-etolite na radiator grill na pipeline mgbidi.
- Ethanediol
Mmanya juru dihydric, enweghị isi na enweghị isi. Mmiri mmiri na-egbu egbu na-egbu egbu nke nwere ebe na-ekpo ọkụ nke -12 Celsius. Nwere mmetụta mmanụ mmanu. Iji nweta antifirizi a kwadebere, a na-eji ngwakọta nke 75% ethylene glycol na 25% mmiri. A na-eleghara ọdịnaya nke mgbakwunye (ihe na-erughị 1%).
- Propanediol
Ọ bụkwa propylene glycol - homologue kacha nso nke ethanediol nwere carbon carbon atọ na agbụ. Mmiri mmiri na-adịghị egbu egbu nwere ntakịrị ụtọ ilu. Mgbochi azụ ahịa nwere ike ịnwe 25%, 50%, ma ọ bụ 75% propylene glycol. N'ihi ọnụ ahịa dị elu, a na-eji ya eme ihe ugboro ugboro karịa etanediol.
Ụdị ihe mgbakwunye
Ethylene glycol antifreeze maka ụgbọ ala oxidizes n'oge ogologo oge ọrụ na-etolite glycolic, obere oge formic acid. Ya mere, a na-emepụta gburugburu acid na-adịghị mma maka ígwè. Iji wepu usoro oxidative, a na-ewebata ihe mgbakwunye mgbochi corrosion n'ime ngwa nju oyi.
- Inorganic corrosion inhibitors
Ma ọ bụ "omenala" - ngwakọta dabere na silicates, nitrate, nitrite ma ọ bụ phosphate salts. Ihe mgbakwunye dị otú ahụ na-arụ ọrụ dị ka ihe nchekwa alkaline ma na-emepụta ihe nkiri inert na elu igwe, nke na-egbochi mmetụta nke mmanya na ngwaahịa oxidation. Edebere ihe mgbochi na ihe mgbochi inorganic na aha "G11" ma nwee agba ndụ ndụ ma ọ bụ anụnụ anụnụ. A na-etinye ihe mgbochi inorganic n'ime ngwakọta nke antifirizi, ihe oyi na-eme n'ụlọ. Ndụ ọrụ bụ naanị afọ 2.
- Ihe mgbochi Organic
N'ihi obere akụrụngwa nke inorganic inhibitors, e mepụtala ihe atụ ndị na-anabata gburugburu ebe obibi na kemịkalụ, carboxylates. Nnu nke carboxylic acid anaghị echebe ebe niile na-arụ ọrụ, kama ọ bụ naanị etiti corrosion, na-ekpuchi ebe ahụ na ihe nkiri dị mkpa. Akpọrọ aha "G12". Ndụ ọrụ - ruo afọ 5. Ha na-acha uhie uhie ma ọ bụ pink.
- agwakọta
N'ọnọdụ ụfọdụ, a na-agwakọta "organics" na "inorganics" iji nweta ngwakọ antifreezes. Mmiri mmiri bụ ngwakọta nke carboxylates na inorganic salts. Ogologo oge eji eme ihe abụghị ihe karịrị afọ 3. Agba ndụ ndụ.
- Lobrid
Ngwakọta nke itinye uche n'ọnọdụ dị otú ahụ gụnyere ịnweta reagents na organic mgbochi corrosion mgbakwunye. Nke mbụ na-etolite nanofilm n'elu dum elu nke ígwè, nke ikpeazụ na-echebe ebe ndị mebiri emebi. Okwu ojiji ruru afọ 20.
nkwubi
Igwe oyi na-ebelata ebe mmiri na-ajụ oyi ma na-ebelata ọnụọgụ nke mgbasawanye. Ngwakọta kemịkalụ nke antifreeze bụ ngwakọta nke mmiri a na-ekpo ọkụ na mmanya na-egbu egbu, ma gụnyekwara ihe mgbochi corrosion na agba.
