Petroleumjellie

Petroleumjellie is 'n semi-vloeibare mengsel van alkielkoolwaterstowwe of versadigde koolwaterstowwe, ook genoem petrolatum, wat deur fraksionele distillasie van petroleum vervaardig word. Sy toestand is tussen vaste stof en vloeistof by kamertemperatuur, en dit het drie kleure bruin, geel en wit vir verskillende doeleindes.

Natuurlike petroleumjellie is afgelei van petroleumresidukonsentraat soos alkielkoolwaterstof swaar olie. Kunsmatige petroleumjellie word verkry uit 'n mengsel van minerale olie wat verdik is met suiwer gemaalde was of paraffien en paraffienvet. Petroleumjellie het 'n minerale olie reuk, nie 'n keroseen reuk nie. Dit kan as grondstof vir medisyne en skoonheidsmiddels gebruik word, en kan ook vir masjiensmeer gebruik word.

Die samestelling van petroleumjellie is tussen en, 'n polimeerkoolwaterstof wat uit petroleumfraksies verkry word, en die distillasietemperatuur is bo 303 ° C. Sy soortlike gewig is tussen 0,820 en 0,865, onoplosbaar in water, maar oplosbaar in petrol en denneolie.

Petroleumjellie is 'n kleurlose, reuklose, nie-fluoresserende deursigtige olierige vloeistof wat verkry word deur diep raffinering van petroleum smeerolie distillaat, met 'n druppelpunt van ongeveer 37-54 grade Celsius. Vry van enige bymiddels, vog en meganiese onsuiwerhede. Oplosbaar in eter, chloroform, petrol en benseen en ander organiese oplosmiddels. Onoplosbaar in water. Goeie chemiese stabiliteit en oksidasieweerstand, met goeie antioksidantstabiliteit, stabiliteit en ligstabiliteit.

Vaseline kan vir mediese doeleindes gebruik word: Vaseline is hoofsaaklik 'n chemies inerte koolwaterstof en het geen bakteriedodende krag nie; Maar dit is nie hidrofiel nie, sal nie geabsorbeer word nie, gesmeer op die vel kan 'n film op sy oppervlak vorm, sodat water nie maklik is om te verdamp en te verloor nie, kan die vel klam hou, bakterieë uit die lug en velkontak blokkeer, daardeur die moontlikheid van infeksie te verminder.

Benewens die gebruik as infiltrerende en vulkapasitors, kan Vaseline ook as roes- en waterafstotend gebruik word. Wanneer waterdigte film gemaak word, sal dit 'n waterdigte film produseer na herhaalde laag 2-3 keer na droog.

Elektrisiëns smeer Vaseline tussen die kabel en die aansluitboks aan om dit te smeer.

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.

Wat is hierdie produk?

Petroleum jelly is a semi-liquid mixture of alkyl hydrocarbons or saturated hydrocarbons, also called petrolatum, produced by fractional distillation of petroleum.The composition of petroleum jelly is between and, a polymer hydrocarbon obtained from petroleum fractions, and the distillation temperature is above 303 ° C. Its specific gravity is between 0.820 and 0.865, insoluble in water, but soluble in gasoline and pine oil.

Toepassing

Vaseline kan vir mediese doeleindes gebruik word: Vaseline is hoofsaaklik 'n chemies inerte koolwaterstof en het geen bakteriedodende krag nie; Maar dit is nie hidrofiel nie, sal nie geabsorbeer word nie, gesmeer op die vel kan 'n film op sy oppervlak vorm, sodat water nie maklik is om te verdamp en te verloor nie, kan die vel klam hou, bakterieë uit die lug en velkontak blokkeer, daardeur die moontlikheid van infeksie te verminder.

It can also be used for mechanical lubrication in the cosmetic, food and textile industries.

In addition to being used as infiltrating and filling capacitors, Vaseline can be used as rust and water repellent.
