Hur rostskyddar man bilen undertill?
Man får ju hissa upp, försöka skrapa bort den rost som finns (bara
ytrost i mitt fall).
Sen ska man väl spraya på avfettningsmedel och spola rent med högtryck.
Vad gör man sen? Vilka produkter är bra och lämpliga för en
hobby-mekaniker i en GDS-hall?
Naturligtvis gäller sunt förnuft med högtrycket men finns de nån del som
är känslig på undersidan?

Rå linolja funkar bra. Miljövänligt också. Blir det något över kan du
använda det som salladsdressing :-)

Jajja men!!! RÅ LINOLJA är JÄTTEBRA som rostskydd.
//Claes.
Linolja har en täckande ej rostskyddande funktion samma som rostskyddsmassa.
Därför skall en tunnflytande rostskyddsmedel som innehåller inhibitorer
användas innan ett täckande lager av rostskyddsmassa läggs på. Om man
tillsätter inhibitorer till linoljan så gissa jag att den blir lika
effektiv. Känner ej till om detta finns att köpa separat. Speciellt effektiv
är dinotrortofenol, vilket ett företag byggdes upp kring nämligen AstraDinol
numera Dinol
Ett utklipp:
There are many ways to describe Dinol. One is how a surgeon's idea
developed into a world wide company in a completely different business.
But, as is often the case, it began several years before that.
Around 1937, a former consultant at Sahlgrenska Hospital in Gothenburg,
Professor and surgeon Sven Johansson, began experimenting in his spare time
to try and improve the resistance to corrosion of stainless steel. He noted
that stainless steel surgical instruments which had been submerged in
disinfection liquid began to corrode. Sven Johansson started to investigate
if adding various water-soluble chemicals could stop the process. Previous
experience had shown that some substances worked, but he was the first to
try with others such as dinitro-ortho compounds. Sven Johansson applied
for a patent in some 25 countries and then turned to Astra as a partner.
Astra, Tika, Tikamin and Hässle
Astra acquired Tika in Stockholm in 1939 and three years later, in 1942,
Tika registered a subsidiary, AB Tikamin, to "buy and sell fixed and
portable goods". In the same year, Astra acquired from pharmacist Paul G.
Nordström in Hässleholm his "factories for pharmaceuticals and water" and AB
Hässle was registered as a pharmaceutical company.
The company in Hässleholm was restructured in 1944 to AB Hässle-Paul
Nordström's factories and later to Hässle-Tika. From 1944 to 1946 Professor
Sven Johansson's development work was taken over by Hässle in Hässleholm to
try and produce a more effective corrosion inhibitor that were soluble in
organic solvents.
Astra set up AB Tikamin in 1947 as a company for the production of
anti-corrosion materials as well as for domestic, cosmetic and body care
products with its factory in Eslöv.
It was then that the Dinitrol trademark was dusted off, reintroduced and
launched as the"anti-corrosion material Dinitrol".
In the first place the only customers were in mechanical industries with a
wide variety of anti-corrosion materials for different applications as well
as rust remover, rut loosener, crack indicator, paints etc.
The factory in Eslöv soon became too small and when Astra also wanted to
transfer the manufacture of Swix ski wax, cellulose sponges and several
other successful products to Tikamin at the same time as Hässle's
manufacture of pharmaceuticals in Hässleholm was to be move to Södertälje
and its administration and development to Gothenburg. The municipality of
Hässleholm was foresighted enough to offer Astra a suitable plot for the new
factory. The old one was in the middle of the town on Vattugatan.
In 1952 a real Astra-man, Sven Lindh, was commissioned to supervise the
building and moving of the company and factory in Eslöv to Hässleholm. he
had wandered the so-called "long road" within Astra, from positions in
Södertälje, Buenos Aires and New York to the MD's chair at Tikamin. After
less than a year, in July 1953, production was underway in Hässleholm
without any interruptions. Hässle-Tika moved to Gothenburg in 1954.
Tikamin now had upwards of 100 products together with subcontracted
production of Astra's subsidiary Wallco such as Swix ski was, cellulose
sponge, K2r stain paste and various cosmetics.
THE INDUSTRIAL MARKET:
Sales of Dinitrol products were initially through agents such as Carl Edhall
in Malmö, Olof Söderberg in Gothenburg, Holger Andreasson in Örebro and
Ramströms in Härnösand. The company also had three traveling salesmen.
Dinol's staff was also engaged as consultants and gave lectures on
corrosion. Major customers at the time included Götaverket, Kockum, Swedish
Rail, the Defense Suppliers, ASEA, Sandviken's Ironworks, Uddeholm companies
and many more.
1955 saw the start of significant sales of body work oil to Svenska
Stålpressnings AB in Olofström for protecting the bodywork of Volvos during
transport to Gothenburg. These deliveries formed around 80 per cent of the
company sales for several years. Major testing of products for this
purpose was carried out every few years to compare them with competitors'
products. Some 10 bodies were treated with each product, sprayed with water
by Olofström's fire brigade to simulate rain and were then judged on arrival
in Gothenburg for their corrosion protection properties and ease of removal.
These tests, and above all the business were so important that, apart from
being present for the actual spraying and inspection in Gothenburg, it was
ensured there was no interference during transport. Guards were posted at
the stations where the train made longer stops to prevent sabotage to the
bodies. Deliveries of the product continued until 1967 while bodies were
manufactured at Olofström.
In January, 1961, Dinitrol 112 was launched. This product was much sought
after and would take up the challenge from the worst competitor. It was
initially made under license from Daubert Chem Co., USA and opened a large
market for us. In the same year, the "crocodile" was launched in Swedish
corrosion protection. A series of advertisements warned of cracking in the
corrosion protection film and likened the pattern formed with the skin of a
crocodile. Changes in recipies were based on developments carried out among
others at Astra's chemical laboratory in Malmö.
VEHICLE CORROSION PROTECTION
The problem with severe corrosion on vehicles first appeared with the change
from the strong frame structure to hollow members of sheet metal. This
change was primarily carried out to reduce vehicle weight. An aggressive
corrosion climate was thus created on the insides of the members and above
all obviously reduced the tolerance for material loss.
Furthermore, corrosive rust in the spot welds constituted a traffic hazard.
A Tikamin advertisement in 1947 proposed painting vehicles with Dinitrol for
the first time. During the latter half of the fifties, the so-called ML
method was launched based on the cooperation between the Swedish Automobile
Association, Motormännen (M), Sven Laurin (L) who was technical manager for
the Association's station in Gothenburg and supplier of corrosion protection
materials, Tikamin.
By the end of the fifties, more than 1000 vehicles had been involved in
developing the ML method.
Dinitrol's breakthrough as a general treatment for protection vehicles
against corrosion came in 1959.
A Ford buyer insisted that his car be sprayed with oil. The Ford agents in
Gothenburg, Viklunds, were put in contact with Sven Laurin. it was the
beginning of Viklund's vehicle corrosion protection treatment and the method
was presented in the first edition in 1960 of Motor.
During the first years of the sixties, Helge Persson, Dinol's "professor of
corrosion protection", developed spraying schedules for different cars,
instructions, tools, machines and products. Tikamin began training the
staff of leading petrol stations in corrosion protection to sell the
products and not least to establish a systematic corrosion protection
business under the name of the ML method on ML stations.
