Gelatina de petroli

La vaselina és una mescla semilíquida d'hidrocarburs alquils o hidrocarburs saturats, també anomenada vaselina, produïda per destil·lació fraccionada del petroli. El seu estat és entre sòlid i líquid a temperatura ambient, i té tres colors de marró, groc i blanc per a diferents finalitats.

La vaselina natural es deriva del concentrat de residus de petroli com l'oli pesat d'hidrocarburs alquil. La vaselina artificial es deriva d'una barreja d'oli mineral espessit amb cera mòlta pura o greix de parafina i parafina. La vaselina té una olor d'oli mineral, no una olor de querosè. Es pot utilitzar com a matèria primera per a medicaments i cosmètics, i també es pot utilitzar per a la lubricació de màquines.

Exhibició del producte

La composició de la vaselina es troba entre i, un hidrocarbur polimèric obtingut a partir de fraccions del petroli, i la temperatura de destil·lació és superior a 303 ° C. La seva gravetat específica està entre 0,820 i 0,865, insoluble en aigua, però soluble en gasolina i oli de pi.

La vaselina és un líquid oliós transparent incolor, inodor i no fluorescent obtingut per refinació profunda del destil·lat d'oli lubricant de petroli, amb un punt de gota d'uns 37-54 graus centígrads. Lliure de qualsevol additiu, humitat i impureses mecàniques. Soluble en èter, cloroform, gasolina i benzè i altres dissolvents orgànics. Insoluble en aigua. Bona estabilitat química i resistència a l'oxidació, amb bona estabilitat antioxidant, estabilitat i estabilitat a la llum.

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.
