Mafuta oziziritsa. Kodi mungapewe bwanji?
Kutsika kwakukulu kwa kutentha sikungathe koma kumakhudza oyendetsa galimoto. Magalimoto ena anaimitsidwa chifukwa cha mabatire akufa. Ena anasiya kupereka mafuta. Mafuta a dizilo amakhudzidwa makamaka ndi "kuzizira".
"Kuzizira" ndi crystallization wa paraffin mu mafuta dizilo. Lili ndi mawonekedwe a flakes kapena tinthu tating'onoting'ono tomwe timalowa mu fyuluta yamafuta, kutsekereza, kutsekereza kutuluka kwa mafuta a dizilo m'zipinda zoyaka.
Mafuta a dizilo ali amitundu iwiri - chilimwe ndi chisanu. Madeti a kupezeka kwawo amafotokozedwa mwalamulo. Mafuta oyenera amafika kwa operekera pa nthawi yoyenera. M'chilimwe, mafuta amatha kuzizira ngakhale pa 0 ° C. Mafuta osinthika omwe amapezeka pamasiteshoni kuyambira Okutobala 1 mpaka Novembala 15 amaundana pa -10 ° C, ndipo mafuta achisanu, omwe amakhala ogawa kuyambira Novembara 16 mpaka Marichi 1, atalemeretsedwa bwino, amaundana pansi -20 ° C (gulu lachisanu F), ndipo ngakhale - 32 ° С (mafuta a dizilo a gulu la arctic 2).
Komabe, zitha kuchitika kuti mafuta ofunda pang'ono amakhalabe mu thanki, omwe amatsekereza fyuluta. Kodi kuchita zinthu zikatero?
Malo omwe mafuta amaundana nthawi zambiri amakhala ovuta kuwapeza. Njira yotsimikiziridwa, ngakhale yokhalitsa, ndikuyika galimoto mu garaja yotentha. Tsoka ilo, kupukuta koteroko kumatenga nthawi yayitali. Ndikwabwino kugwiritsa ntchito zowonjezera zamafuta zomwe zimamanga madzi ndikuletsa mvula ya parafini.
Mafuta sangawonjezere ku mafuta a dizilo. Mapangidwe akale a injini ya dizilo amatha kuthana ndi izi, koma m'mainjini amakono zitha kupangitsa kuti jakisoni awonongeke kwambiri.
Komanso zogulitsa pali zowonjezera ku petulo. Amamanga madzi pansi pa thanki, kusungunula mafuta ndi kuteteza kuti asaundanenso. Komanso, musaiwale kuyendetsa ndi tanki yodzaza kwambiri m'nyengo yozizira, njirayi sikuti imateteza ku dzimbiri, komanso imapangitsa kuti injiniyo ikhale yosavuta. Mafuta akazizira, samasintha nthunzi bwino. Izi zimapangitsa kuti zikhale zovuta kuyatsa kusakaniza mu silinda, makamaka pamene kuli kochepa kwambiri.
Kuyika ndalama pafupifupi ma zloty khumi ndi awiri muzowonjezera mafuta m'nyengo yozizira ndi lingaliro labwino kwambiri. Kuwonjezera pa kusunga nthawi, dalaivala amapewa kupanikizika kowonjezereka komwe kumagwirizanitsidwa, mwachitsanzo, ndi kuyenda. Komanso, palibe chifukwa choyang'ana ma patent kuti achepetse mafuta mwachangu, zomwe zitha kukhala zodula malinga ndi zotsatira zake.
