Ka wai kaʻa dot-4. ʻO wai ka maikaʻi?
Hoʻohui a me nā hiʻohiʻona o ka wai kaʻa DOT-4
ʻO DOT-4 he 98% polyglycols. ʻO ke koena 2% he mea hoʻohui.
He mea nui ka hoʻomaopopo ʻana aia kahi maʻamau e hoʻoponopono i ka hoʻohui ʻana o nā wai hoʻomaha. Hana ʻia kēia maʻamau a mālama ʻia e ka US Department of Transportation. A ʻo kēlā me kēia wai, me ka ʻole o ka mea hana, ma ke kumumanaʻo pono e hoʻokō me nā ʻano i kuhikuhi ʻia i ka maʻamau, inā pili ia i ka ʻohana DOT. I ka hoʻomaʻamaʻa ʻana, ʻaneʻane like kēia, ma ka liʻiliʻi loa no nā hōʻailona kaulana.
Nui nā hiʻohiʻona i hoʻoponopono ʻia. ʻO ka mua, ʻo ia ke kumu. ʻO ka DOT-4 brake fluid base he mau waiʻona paʻakikī, nā polyglycols i kapa ʻia. He maikaʻi ka lubricity o kēia mau waiʻona, ʻaʻole hiki ke hoʻopili ʻia, e hoʻomau i ka hana a hiki i -42 ° C ma ka awelika, a e hoʻolapalapa i kahi mahana ʻaʻole i emi ma lalo o +230 ° C. Eia kekahi, ʻo nā waiʻona āpau o ka pūʻulu glycol e hōʻike ʻia e ka hygroscopicity - ka hiki ke komo i ka wai mai ke kaiapuni a hoʻoheheʻe i ka wai i kona nui me ka ʻole o ka sediment.
ʻO ka lua, he pūʻolo o nā mea hoʻohui. Hoʻonui nā mea hoʻohui i nā waiwai hana o ka wai. Hoʻoponopono pū ʻia ke ʻano o nā additives. A ma nā huaʻōlelo qualitative a me quantitative.
ʻO ia ke ʻano inā kūʻai ʻoe i ka wai kaʻa i kapa ʻia ʻo DOT-4, a laila e hōʻoiaʻiʻo ʻia e loaʻa ka palena liʻiliʻi o kēlā mau ʻāpana e hōʻoia i kāna hana i loko o nā palena i hōʻike ʻia e ka maʻamau.
Eia nō naʻe, ʻae ka hoʻoponopono i ka hoʻohui ʻana i nā ʻāpana ʻaoʻao ʻekolu a i ʻole ka hoʻonui ʻana i ka hapa (ʻaʻole i ka emi ʻana), hiki ke hoʻololi i kekahi o nā ʻano o ka wai kaʻa. ʻO ka maʻamau no ka maikaʻi. No ka laʻana, hoʻemi lākou i ka viscosity haʻahaʻa haʻahaʻa, hoʻonui i ka helu hoʻolapalapa, a i ʻole e hoʻohaʻahaʻa i ka wai i ke kaʻina hana o ka hoʻomoʻa ʻana i ka wai mai ka lewa.
ʻO nā mea hana ke nānā wale
Hoʻopiha ʻia ka mākeke hou me nā hāʻawi o DOT-4 class brake fluid. E nānā kākou i kekahi mau huahana kaulana i ka piʻi ʻana o ke kumu kūʻai, e hoʻomaka ana me ka liʻiliʻi loa.
- ʻO Dzerzhinsky DOT-4. He 220-250 rubles no ka lita. ʻAʻole e hoʻolapalapa a hiki i +260 ° C. Hoʻomanawanui maikaʻi ʻo ia i nā wela maikaʻi ʻole, ma ka liʻiliʻi e kūpono i ka maʻamau. Eia nō naʻe, ʻaʻole i loko o kāna haku nā mea ʻē aʻe e kūʻē i ka absorption o ka wai mai ke kaiapuni. Pono e hoʻololi pono ma hope o 2 mau makahiki, me ka nānā ʻole i ka ikaika o ka hoʻohana ʻana i ke kaʻa. Kūpono no nā hiʻohiʻona VAZ maʻamau, nā kaʻa haole kahiko a i ʻole nā kaʻa ʻē aʻe me nā pahu pahu. Hiki ke hoʻohana ʻia i nā kaʻa hou, akā he mea nui e hahai i ka papa hana pani.
- ʻO Syntec Super DOT4. ʻO kahi koho makamae ʻē aʻe. ʻO ke kumukūʻai ma kahi o 300 rubles no 1 lita. ʻAʻole e hoʻolapalapa a hiki i +260 ° C, ʻaʻole e maloʻo a hiki i -40 ° C. Makemake ʻia e hoʻonui i kēia wai i ka ʻōnaehana ma hope o 2 mau makahiki o ka hoʻohana ʻana. Ua hōʻike maikaʻi ʻia i nā VAZ kahiko, e like me Granta a me Priora.
- TRW Wai Paʻa DOT ʻO ka wai mai kahi mea hana kaulana i nā mea waiwai a me ke kūlana kiʻekiʻe a me nā ʻōnaehana braking. ʻO ke kumukūʻai ma kahi o 400-500 rubles no 1 lita. Loaʻa nā manaʻo maikaʻi ma ka pūnaewele mai nā mea nona nā kaʻa.
- ʻO Bosch DOT4. ʻAʻole pono ka mea hana i ka hoʻolaha. ʻO ke kumukūʻai no 1 lita ma kahi o 500 rubles. ʻOiai nā hiʻohiʻona haʻahaʻa haʻahaʻa i haʻi ʻia (ʻo + 230 ° C wale nō ka paila, ʻo ia hoʻi, ma ka pae haʻahaʻa i ʻae ʻia), ʻike ʻia ia e kona ʻano paʻa. Hoʻomaopopo ka poʻe kaʻa ʻoiai ma hope o 3 mau makahiki o ka hana, i ka nānā ʻana i ka wai no ka ʻike wai, ʻaʻole kākau mau ka mea hoʻāʻo iā ia me he mea hiki ʻole ke hoʻohana ʻia, akā ke ʻōlelo nei i kahi pani.
- Pentosin Super DOT 4 hoʻohui. ʻO ka wai me nā hiʻohiʻona haʻahaʻa haʻahaʻa a kiʻekiʻe. He kūpono no ka hoʻohana ʻana i nā kaʻa haole me nā disc brakes. Ma kahi kūlana "maloʻo", ʻaʻole ia e paila a hiki i +260 ° C.
- Aila-Synthesis FELIX DOT4. ʻO ka huahana kūloko mai ka māhele kumu kūʻai waena. Ua hōʻoia ʻo ia iā ia iho ma nā kaʻa kūloko a ma nā kaʻa haole. Hoʻohana maikaʻi ʻia ia i nā ʻōnaehana brake o nā kaʻa Iapana, e like me Mitsubishi Lancer 9 a me Honda Accord 7. Wahi a nā hopena o nā hoʻokolohua kūʻokoʻa, ua hōʻoia piha ʻo FELIX DOT4 i nā ʻano i haʻi ʻia e ka mea hana.
- ʻO ka wai kaʻaahi Castrol DOT ʻO ka wai me ka wai wela haʻahaʻa kiʻekiʻe a me ke kūpaʻa paila maikaʻi. ʻO ka awelika o 600-700 rubles no ka lita. ʻO ka brand i kēia hihia ke kamaʻilio eloquently nona iho. Loaʻa ka hapa nui o nā loiloi maikaʻi wale nō ma ka pūnaewele.
- VAG DOT 4. ʻO ka wai hōʻailona no nā kaʻa o ka hopohopo VAG. Ma waho aʻe o ke kumukūʻai (e pili ana i 800 rubles no 1 lita), ʻaʻohe ona drawbacks.
Ke koho ʻana i kahi wai kaʻa, pono ʻoe e alakaʻi ʻia e kekahi mau lula. ʻO ka mea mua, mai kūʻai aku i nā wai o nā hōʻailona hiki ʻole ke hoʻomaopopo ʻia, ʻoi aku ka maikaʻi o nā mea i ʻoi aku ka maikaʻi ma mua o ke kumu kūʻai haʻahaʻa loa no kahi huahana mai nā mea hana ʻoi aku ka maikaʻi. ʻO ka lua, e hoʻāʻo e ʻike i ka wai a ka mea hana kaʻa e paipai ai. ʻO ka pinepine, he hana hoʻolaha wale nō kēia. Eia naʻe, inā ʻōlelo ʻia kahi wai e ka mea hana kaʻa, a laila 100% kūpono ia me kāu ʻōnaehana brake.
A ʻo ka mea nui loa: mai poina e hoʻololi i ka wai hoʻomaha ma mua o 3 mau makahiki o ka hana. ʻO nā koho kumukūʻai ma hope o 3 mau makahiki e hōʻiliʻili i ka nui o ka wai i loko o kā lākou leo, hiki ke alakaʻi i ka hoʻolapalapa koke ʻana o ka wai i loko o ka ʻōnaehana a hoʻopau a hapa ʻole paha o nā kaʻa.
