Mafuta "Kalosha". Katundu ndi ntchito

makhalidwe a

Mtundu uwu wa nefras umagwiritsidwa ntchito kwambiri m'makampani, ngakhale kuti pang'onopang'ono umachotsedwa ntchito ndi zosungunulira zochepa za carcinogenic komanso zosayaka.

Makhalidwe apamwamba kwambiri:

1. Kutentha kodziwotcha_- 190 ... 250 ° C.
2. Chemical zikuchokera - organic hydrocarbon mankhwala, chiwerengero cha maatomu mpweya umene ranges kuchokera 9 mpaka 14.
3. Mtundu - wachikasu wopepuka kapena (nthawi zambiri) - wopanda mtundu.
4. Chiwerengero cha octane ndi pafupifupi 52.
5. Zowonjezera palibe.
6. Zonyansa: kukhalapo kwa mankhwala a sulfure kumaloledwa, chiwerengero chonse (mwa mawu a sulfide) sichiposa 0,5.
7. Kachulukidwe - 700…750 kg/m³.

Zizindikiro zina za mafuta a Kalosh zimasiyana, malingana ndi makampani omwe amagwiritsira ntchito. Chodziwika bwino ndi chakuti ma alkanes omwe amaphatikizidwa mu mankhwala a nefras onse ali pafupi ndi cycloparaffins ya mafuta osakanizidwa. Zotsatira zake, ukadaulo waukulu wopangira mafuta a Kalosh ndikugawa pang'onopang'ono.

Zotsatira zamafuta amafuta zimagwiritsidwa ntchito kusungunula inki zosindikizira, mankhwala ophera tizilombo, mankhwala ophera tizilombo, zokutira, phula lamadzimadzi ndi zinthu zina zakuthupi, kuphatikiza mphira. Amagwiritsidwanso ntchito kuyeretsa zida zomangira makina komanso zopangira zitsulo kuti zisamaipitsidwe pokonza (zomwe zimapangitsa kuti mankhwalawa akhale ofanana ndi mafuta ena amafuta, makamaka mafuta a B-70). Musagwiritse ntchito mankhwalawa pa kutentha kozungulira 30⁰C.

Brands ndi zofunika chitetezo

Nefras amapanga magiredi awiri: C2 80/120 ndi C3 80/120, zomwe zimasiyana kokha muukadaulo wopanga ndi kuyeretsa. Makamaka, popanga C2 80/120, petulo yomwe idasinthidwa kothandizira imagwiritsidwa ntchito ngati zida zomaliza zomaliza, komanso C3 80/120, petulo yomwe imapezedwa mwachindunji ndi distillation imagwiritsidwa ntchito. Kwa nefras C2 80/120 ya kalasi yoyamba, kachulukidwe kake ndi kochepa.

Chisamaliro chapadera chimaperekedwa ku malamulo ogwiritsira ntchito bwino mitundu ya mafuta omwe akufunsidwa. Tiyenera kukumbukira kuti kung'anima kwa zinthu zoterezi ndi kochepa kwambiri, ndipo kokha -17 kwa crucible yotseguka.⁰C. Mukamagwiritsa ntchito, kuphulika kwa chinthucho kuyeneranso kuganiziridwa. GOST 443-76 imatanthawuza chizindikiro ichi ngati chowopsa kale pamene ndende ya nefras mu nthunzi ya mpweya ndi yoposa 1,7%. Kuchuluka kwa nthunzi ya petulo mumlengalenga wa chipindacho sikungakhale kopitilira 100 mg/m²³.

Nthawi zambiri pamakhala chisokonezo muzofunikira zaukadaulo zamafuta osungunulira chifukwa cha kusiyana kwa miyezo yomwe imatsogolera opanga. Choncho, nefras (kuphatikizapo ambiri Nefras C2 80/120) amapangidwa mogwirizana ndi GOST 443-76, ndi mafuta "Kalosh" amapangidwa malinga specifications mwachionekere n'zochepa kwambiri. Komabe, molingana ndi chilinganizo ndi katundu, ichi ndi chinthu chofanana, chosiyana kokha pamlingo woyenga (kwa mafuta a Kalosh, digiri iyi ndi yotsika). Choncho, kuchokera kumalingaliro enieni, mafuta a Br-2, mafuta a Kalosh ndi Nefras C2 80/120 ndi chinthu chimodzi.

Ntchito

Kutengera kuchuluka kwa zinthu zake, mafuta a Kalosh amatengedwa ngati mafuta osungunulira, koma malo ake ogwiritsira ntchito mabasi ndi okulirapo:

• Zoyatsira mafuta.
• Kuyeretsa matanki ndi malo osungiramo zomera zodulira mafuta oxy.
• Kukonzekera nsalu zopaka utoto.
• Degreasing zipangizo zamagetsi pamaso soldering.
• Kuyeretsa zodzikongoletsera.
• Sitovu zothira mafuta ndi zida zina zotenthetsera ntchito zokopa alendo.

Mafuta a Kalosh sayenera kudziwika kwathunthu ndi mafuta a Br-2. Amapangidwa kuchokera kuzinthu zosiyanasiyana zopangira ndikuyesedwa zomwe zili m'zigawozo ndi njira zosiyanasiyana, makamaka pamene wopanga amayambitsa zowonjezera zowonjezera muzolemba zazikulu. Kuphatikiza apo, ma nefra onse opangidwa molingana ndi zofunikira zaukadaulo za GOST 443-76 amasiyanitsidwa ndi chizindikiro chokhazikika cha nambala yawo ya octane, yomwe siili yofananira ndi mitundu ina yomwe takambirana m'nkhaniyi.

Mitengo yazinthuzi imatsimikiziridwa ndi kuyika kwa katunduyo. Kwa mafuta a Kalosha, omwe amaikidwa m'chidebe cha malita 0,5, mtengo wake umachokera ku 100 ... 150 rubles, pakuyika mu zitini za malita 10 - 700 ... rub/kg.

Gasoline Galosh zomwe zingagwiritsidwe ntchito.
