Ko antifreeze G12 uye G13 inogona kusanganiswa here?
Zviri mukati
Antifreeze G12 uye G13. Chii chakasiyana?
Iyo yakawanda yakawanda yezvinwiwa zvakagadzirirwa kushandiswa mumasisitimu emazuva ano ekutonhodza mota ane zvinhu zvitatu:
- basic dihydric alcohol (ethylene glycol kana propylene glycol);
- mvura yakadzika;
- pasuru yezvinowedzera (anti-corrosion, inodzivirira, anti-foam, nezvimwewo).
Mvura uye dihydric doro zvinoumba zvinopfuura 85% yehuwandu hwekutonhodza huwandu. Iyo yasara 15% inobva kune zvinowedzera.
Kirasi G12 antifreezes, zvinoenderana neyakagadzika kupatsanurwa, ine matatu makirasi: G12, G12 + uye G12 ++. Nheyo yeese kirasi G12 zvinwiwa zvakafanana: ethylene glycol uye distilled mvura. Misiyano iri mukuwedzera.
G12 antifreeze ine carboxylate (organic) additives. Ivo vanoshanda chete kudzivirira foci yekuora uye havaite inoenderera inodzivirira firimu, sepakirasi G11 inotonhorera (kana yemumba antifreeze). G12+ uye G12++ zvinwiwa zvine zvakawanda zvakasiyana. Iwo ane ese ari maviri organic uye inorganic additives inokwanisa kugadzira firimu rekudzivirira pameso eiyo inotonhorera sisitimu, asi yakanyanya kutetepa pane iyo yekirasi G11 inotonhorera.
G13 antifreeze ine base ye propylene glycol uye distilled mvura. Ndiko kuti, doro rakatsiviwa, izvo zvinovimbisa kushorwa kwekuumbwa kwechando. Propylene glycol haina muchetura uye haina makemikari ane hutsinye kupfuura ethylene glycol. Zvisinei, mutengo wekugadzirwa kwayo wakapetwa kakawanda kupfuura we ethylene glycol. Panyaya yemaitiro ekuita, maererano nebasa mumotokari inotonhorera system, musiyano pakati pezvinwiwa izvi mudiki. Zvinowedzerwa mukirasi G13 antifreezes zvakasanganiswa, zvakafanana mumhando uye huwandu kune G12 ++ inotonhorera.
G12 uye G13 antifreeze inogona kusanganiswa here?
Iko hakuna mhinduro chaiyo kumubvunzo wekuti zvinokwanisika kusanganisa antifreeze makirasi G12 uye G13. Zvakawanda zvinoenderana nekugadzirwa kweiyo inotonhorera system uye chiyero chekusanganisa zvinwiwa. Funga nyaya dzinoverengeka dzekusanganisa G12 uye G13 antifreezes.
- Muchirongwa umo G12 antifreeze kana imwe yemamwe madiki akazadzwa mukati, G20 antifreeze inowedzerwa zvakanyanya (kupfuura 13%). Kusanganiswa kwakadaro kunogamuchirwa, asi hakukurudzirwi. Kana yakasanganiswa, zvinwiwa zvedoro hazvizodyidzana. Mvura inowanikwa nekusanganisa antifreezes G12 uye G13 inoshandura zvishoma nzvimbo yechando, asi ichi chichava shanduko shoma. Asi zvinowedzera zvinogona kupinda mukukonana. Kuedza kwevanofarira mune izvi kwakapera nemhedzisiro yakasiyana, isingafungidzike. Mune zvimwe zviitiko, iyo precipitate haina kuoneka kunyange mushure menguva refu uye mushure mekupisa. Mune zvimwe zviitiko, kana uchishandisa zvakasiyana siyana zvezvinwiwa kubva kune vakasiyana vagadziri, inooneka turbidity yakaonekwa mumusanganiswa unoguma.
- Mune sisitimu yakagadzirirwa G13 antifreeze, huwandu hwakakosha (kupfuura 20% yehuwandu hwevhoriyamu) inowedzerwa kukirasi G12 inotonhorera. Izvi hazvigoni kuitwa. Mune dzidziso, masisitimu akagadzirirwa G13 antifreeze haafanire kugadzirwa nezvinhu zvine kudzivirirwa kwakanyanya kubva kukurwisa kemikari, sezvaidiwa kune masisitimu eG12 antifreeze. Propylene glycol ine yakaderera makemikari aggression. Uye kana mugadziri wemotokari akashandisa mukana uyu uye akaita chero zvinhu kubva kune zvisiri zvechinyakare zvinhu, zvino hutsinye ethylene glycol inogona kukurumidza kuparadza zvinhu zvisina kugadzikana kune zvazvinoita.
- Nhamba shoma yeG12 antifreeze inowedzerwa kune system ine G13 antifreeze (kana zvinopesana). Izvi hazvikurudzirwe, asi zvinogoneka kana pasina imwe nzira yekubuda nayo. Ikoko hakuzovi nemhedzisiro yakaoma, uye chero zvakadaro, iyi isarudzo inogamuchirwa pane kutyaira nekushaikwa kwekutonhorera muhurongwa.
Unogona kutsiva zvachose G12 antifreeze neG13. Asi zvisati zvaitika, zviri nani kutsvaira iyo inotonhorera system. Panzvimbo yeG13, haugone kuzadza G12.
