Vazelina

Vazelin je polutekuća smjesa alkilnih ugljikovodika ili zasićenih ugljikovodika, koja se također naziva petrolatum, proizvedena frakcijskom destilacijom nafte. Njegovo stanje je između krutog i tekućeg na sobnoj temperaturi, a ima tri boje smeđu, žutu i bijelu za različite namjene.

Prirodni vazelin dobiva se iz koncentrata naftnih ostataka kao što je alkil ugljikovodik teško ulje. Umjetni vazelin dobiva se iz mješavine mineralnog ulja zgusnutog čistim mljevenim voskom ili parafinom i parafinske masti. Vazelin ima miris mineralnog ulja, a ne miris kerozina. Može se koristiti kao sirovina za lijekove i kozmetiku, a može se koristiti i za podmazivanje strojeva.

Prikaz proizvoda

Sastav vazelina je između i, polimernog ugljikovodika dobivenog iz naftnih frakcija, a temperatura destilacije je iznad 303 ° C. Njegova specifična težina je između 0,820 i 0,865, netopljiv u vodi, ali topiv u benzinu i borovom ulju.

Vazelin je bezbojna, bezmirisna, nefluorescentna prozirna uljasta tekućina dobivena dubokim rafiniranjem destilata naftnog ulja za podmazivanje, s točkom kapanja od oko 37-54 stupnja Celzijusa. Bez ikakvih aditiva, vlage i mehaničkih nečistoća. Topljiv u eteru, kloroformu, benzinu i benzenu i drugim organskim otapalima. Netopljivo u vodi. Dobra kemijska stabilnost i otpornost na oksidaciju, s dobrom antioksidativnom stabilnošću, stabilnošću i postojanošću na svjetlost.

Vaseline can be used for medical purposes: Vaseline is primarily a chemically inert hydrocarbon and has no bactericidal power; But it is not hydrophilic, will not be absorbed, smeared on the skin can form a film on its surface, so that water is not easy to evaporate and lose, can keep the skin moist, block bacteria from the air and skin contact, thereby reducing the possibility of infection.

In addition to being used as infiltrating and filling capacitors, Vaseline can be used as rust and water repellent. When making waterproof film, it will produce a waterproof film after repeated coating 2-3 times after drying.

Electricians apply Vaseline between the cable and the junction box to lubricate it.

It is also used for lubrication of light machinery and precision instruments, mechanical lubrication of makeup, food industry and textile industry.

Petroleum jelly can also be used in many furniture, machinery, etc., to prevent rust, lubrication, repair cracks, etc.

Apply between two direct contact frosted glassware to prevent the glass from biting each other and becoming stuck. Most commonly, glass plugs in burets are coated with a thin layer of vaseline to increase twisting lubrication and seal gaps. To insert the glass tube into the hole of the rubber plug, apply some petroleum jelly to increase the lubrication and make the tube easier to insert.

In addition to the above, thinly applied to the camera lens may create a soft focus hazy effect.
