ʻO ka helu paila o ka antifreeze. E hoʻohālikelike me ka antifreeze

He wahi physics

ʻAʻole pololei ke kamaʻilio e pili ana i ka pae paila o ka antifreeze i nā kikoʻī o ka antifreeze, no ka mea, ʻo ka mea mua, he ʻano kemika ka antifreeze, a ʻo kāna mau ʻano thermophysical i hoʻoholo ʻia ʻaʻole wale ma ka mahana, akā ma ke kaomi pū kekahi. ʻO ka lua, ʻo ka antifreeze, ka mea i hana ʻia i ka manawa hoʻokahi no nā ʻenekini i hana ʻia ma ka home, aia nā mea hoʻohui e hōʻoiaʻiʻo ʻaʻole wale ka hana o ke kaʻa i nā haʻahaʻa haʻahaʻa, akā ʻo kona pale ʻana mai kekahi mau mea ʻino:

• ʻinoʻino;
• nā hoʻokuʻu aku;
• cavitation.

ʻO Antifreeze, ʻaʻole like me nā antifreezes, ʻaʻohe hopena lubricating, a loaʻa ka hoʻohaʻahaʻa lole ma muli o ka emi ʻana o ka mahana o nā mea neʻe o ka huakaʻi, me ka hoʻonui ʻana i koho ʻia nā āpau, a piʻi maoli ka friction coefficient.

Inā ʻoi aku ka liʻiliʻi o nā mea āpau me ka mahana i ʻae ʻia (ʻaʻole ʻoi aku ma mua o 90^ºC), a laila ʻoi aku ka paʻakikī o ke kūlana me ke kaomi ʻana i ka mīkini. No ka pale ʻana i ka ʻenekini mai ka wela nui ʻana, hoʻomake ʻia ka antifreeze i nā kaomi kiʻekiʻe, e pili pū ana i ka mahana o ka wai. No ka hapa nui o nā lama, ʻo ke kaomi maoli i loko o ka poloka cylinder ma ka liʻiliʻi loa he 1,2 ... 1,3 atm: a laila, e like me ke kānāwai Clausius, e piʻi ka nui o ka wela e pono ai no ka hoʻolapalapa wai. No laila, hiki ke 110…112 ka helu hoʻolapalapa ʻae ʻia o nā mea hoʻoluʻu^ºH.

He aha ka lae paila o ka antifreeze?

ʻO ka hoʻoulu ʻana i nā ʻenekini o ia mau mea hoʻonaninani kaulana e like me Felix A40, Motul, Alaska a me nā mea ʻē aʻe e pili ana me ka lawa ʻole o ka antifreeze, kahi hana ʻino o ka ʻōnaehana ea, ke ʻano o ka laka ea, kahi hana ʻino o ka ʻōnaehana hoʻomaha, a i ʻole ka ka hoʻohana ʻana i ka refrigerant haʻahaʻa haʻahaʻa (diluted, spent, etc.). ʻO ke kamaʻilio e pili ana i ka pae paila o ka antifreeze hiki ke hiki wale i nā mea nona nā kaʻa e ʻae i ka nui o ke kaomi coolant a me ka nui o ka nui i loko o ka ʻōnaehana hoʻomaha. ʻO kekahi mea ʻē aʻe ka hoʻohana ʻana i nā wai e like me antifreeze ma kahi o ka antifreeze (kūʻai ʻia ma nā mākeke kaʻa kānalua). Hiki i kēlā mau mea ke hoʻolapalapa, a hiki i nā mahana o 90^ºH.

Nā waiwai Thermophysical o nā antifreezes o ka hana home

I nā mīkini i hana ʻia e Lūkia, pono e hoʻohana i nā antifreezes o ka Phoenix, Sintec a me nā mea like. ʻO kā lākou palena hana penei:

1. No A40M antifreeze: -40…+108^ºH.
2. No A65M antifreeze: -65…+108^ºH.
3. No A60M antifreeze: -60…+105^ºH.
4. No ka antifreeze TL-30 Premium: -30…+108^ºH.

Ma nā wela o ka ʻenekini i ʻoi aku ka kiʻekiʻe ma mua o nā mea i hōʻike ʻia, e paila ka antifreeze.

Aia ka coefficient o ka hoʻonui volumetric o ka antifreeze i loko o 1,09 ... 1,12. Hoʻoholo ʻia nā hōʻailona ʻē aʻe e nā koi loea o GOST 28084-89.

Hoʻohālikelike ʻia ka helu hoʻolapalapa o ka antifreeze e ka waiwai kaomi:

• Ma R = 1 ma T_bale = 105^ºC;
• Ma R = 1,1 ma T_bale = 109^ºC;
• Ma R = 1,3 ma T_bale = 112^ºH.

ʻO ka mea hana nui o nā antifreezes ma ka ʻāina ʻo PKF "MIG a me Co" (Dzerzhinsk, Nizhny Novgorod region).

E hoʻopaʻa i kahi e hoʻolapalapa ai o ka antifreeze (antifreeze)
