Ndi mafuta ati omwe ali abwino kwambiri pamatcheni a njinga zamapiri?

1. Ndi mafuta ati oti musankhe:
Ngati muli ndi bajeti yaying'ono, sankhani mafuta amchere, koma moyo wake umakhala wautali kuposa wamafuta opangira.Ngati muyang'ana pa mtengo wonse, kuphatikizapo kupewa dzimbiri la unyolo ndi dzimbiri, ndikuwonjezeranso maola a munthu, ndiye kuti ndizotsika mtengo kugula mafuta opangira.Sungani ntchito.
Mafuta opangira unyolo pamsika amatha kugawidwa m'mitundu iwiri: 1. esters ndi 2. mafuta a silicone.
Tiyeni tikambirane za mtundu woyamba: Ubwino waukulu wa ester ndikuti umakhala wabwino kwambiri ndipo umatha kulowa mwachangu mumpata pakati pa bushing center ndi mbale yam'mbali ya unyolo (kumbukirani, kusuntha kwa unyolo kumayambitsidwa ndi kuvala pakati bushing center ndi mbale yam'mbali inde, chomwe chimafunika kwambiri kudzoza ndi mkati, osati pamwamba pa unyolo, ndikungoteteza kuti dzimbiri mafuta a unyolo kachiwiri).
Tiyeni tikambirane chachiwiri: Ubwino waukulu wa silikoni mafuta ndi kuti ali bwino madzi kukana, koma permeability ake ndi osauka.Filimu yamafuta ndiyosavuta kusweka, zomwe zimapangitsa kuti mafuta azikhala ochepa komanso kuvala kwambiri pamaketani.Chifukwa chake, mafuta a silicone amakhala othandiza kwambiri akagwiritsidwa ntchito pamalo otsetsereka.
Pomaliza, nthawi zambiri, ma esters ali ndi zotsatira zabwino zolowera m'maketani ndipo ndi oyenera kwambiri ngati mafuta a unyolo kuposa mafuta a silikoni, omwe sangagwirizane ndi dothi.Onse ali ndi zabwino ndi zoyipa zawo, zimatengera zomwe zimagwirizana ndi anzanu.

2. Zofunikira zamafuta pakutumiza kwa njinga:
1: Ali ndi mwayi wodutsa
2: Iyenera kukhala ndi zomatira zabwino kwambiri
3: Kuchita bwino kwambiri kwamafuta
4: Kukhazikika kwabwino kwa okosijeni
5: Imakhala ndi chiwopsezo chochepa kwambiri cha kutaya madzi
6: Khalani ndi luso lolimbana ndi zotsatira zakunja
7: Lili ndi makhalidwe osakhala ndi kuipitsidwa
