Kemikari yeantifreeze g11, g12, g13
Zviri mukati
Component composition
Hwaro hwezvinotonhorera (zvinotonhorera) imvura yakasvibiswa yakasanganiswa nemono- uye polyhydric alcohols muzvikamu zvakasiyana. Corrosion inhibitors uye fluorescent additives (dhayi) zvakare inounzwa mune concentrates. Ethylene glycol, propylene glycol kana glycerin (kusvika 20%) inoshandiswa sedoro.
- mvura distillate
Mvura yakacheneswa, yakapfava inoshandiswa. Zvikasadaro, kuyera muchimiro checarbonate uye phosphate deposits inoumba pane radiator grille uye madziro epombi.
- Ethanediol
Dihydric saturated doro, isina ruvara uye isina kunhuhwirira. Muchetura wemafuta ane muchetura ane chando che -12 °C. Iine zvinhu zvekuzora. Kuti uwane yakagadzirira-yakagadzirwa antifreeze, musanganiswa we75% ethylene glycol uye 25% mvura inoshandiswa. Izvo zviri mukati mezviwedzerwa hazvina hanya (zvisingasviki 1%).
- Propanediol
Iyo zvakare propylene glycol - iyo yepedyo homologue ye ethanediol ine matatu kabhoni maatomu mucheni. Mvura isina chepfu ine kakunaka kanovava. Commercial antifreeze inogona kunge iine 25%, 50%, kana 75% propylene glycol. Nekuda kwekudhura kwakanyanya, inoshandiswa zvishoma kazhinji pane ethanediol.
Mhando dzekuwedzera
Ethylene glycol antifreeze yemotokari oxidizes panguva yekushanda kwenguva refu uye inoumba glycolic, isingawanzoiti formic acid. Nokudaro, nzvimbo ine acidic isina kunaka kune simbi inogadzirwa. Kusabvisa oxidative maitiro, anti-corrosion additives anounzwa mune inotonhorera.
- Inorganic corrosion inhibitors
Kana "chinyakare" - musanganiswa wakavakirwa pane silicates, nitrate, nitrite kana phosphate munyu. Mishonga yakadaro inoita senge alkaline buffer uye inoita firimu inert pamusoro pesimbi, iyo inodzivirira mhedzisiro yedoro uye ayo oxidation zvigadzirwa. Maantifreeze ane inorganic inhibitors akanyorwa nezita rekuti "G11" uye ane ruvara rwegirinhi kana rwebhuruu. Inorganic inhibitors inosanganisirwa mukuumbwa kweantifreeze, inotonhorera inogadzirwa mudzimba. Upenyu hwebasa hunogumira kumakore maviri.
- Organic Inhibitors
Nekuda kweiyo shoma sosi yeinorganic inhibitors, yakawedzera hushamwari uye inodzivirira kemikari analogues, carboxylates, akagadzirwa. Minyu yecarboxylic acids haidziviriri nzvimbo yese yekushanda, asi chete pakati pekuora, inovhara nzvimbo yacho nefirimu yakaonda. Yakasarudzwa se "G12". Upenyu hwebasa - kusvika kumakore mashanu. Idzo dzakatsvuka kana pink muruvara.
- yakasanganiswa
Mune zvimwe zviitiko, "organics" inosanganiswa ne "inorganics" kuwana hybrid antifreezes. Iyo mvura musanganiswa we carboxylates uye inorganic munyu. Nguva yekushandiswa haisi kupfuura makore matatu. Green color.
- Lobrid
Iko kuumbwa kweiyo concentrate mune yakadaro kesi inosanganisira mineral reagents uye organic anti-corrosion additives. Iyo yekare inoumba nanofilm pamusoro pechiso chese chesimbi, iyo yekupedzisira inodzivirira nzvimbo dzakakanganiswa. Nguva yekushandiswa inosvika makore makumi maviri.
mhedziso
Iyo inotonhorera inodzikisa nzvimbo yekuomesa yemvura uye inoderedza coefficient yekuwedzera. Mushonga wemakemikari we antifreeze musanganiswa wemvura yakasvibiswa nedoro, uye inosanganisirawo corrosion inhibitors uye dhayi.
