Description
Fremgangsmåte ved bestrykning av papir eller lignende. Procedure for coating paper or the like.
Oppfinnelsen vedrører en fremgangsmåte ved bestrykning av papir eller lignende, hvor en underlagsbane bestrykes på vanlig måte med en vandig suspensjon som vesentlig består av ett eller flere mineralpigmenter og et klebemiddel, og at den bestrøkne overflate, mens den enda er. våt eller fuktig, presses svakt mot en oppvarmet, polert metalloverflate og deretter tørkes slik at beleggets overflate blir et nøyaktig speilbilde av den overflate som belegget tørkes mot, idet man for å forhindre klebning mellom den glansede metalloverflate av krom og bestrykningssammensetningen og papiret gjør den forkrommede metalloverflate nøytral. The invention relates to a method for coating paper or the like, where a substrate web is coated in the usual way with an aqueous suspension which essentially consists of one or more mineral pigments and an adhesive, and that the coated surface, while it is still. wet or damp, lightly pressed against a heated, polished metal surface and then dried so that the surface of the coating becomes an exact mirror image of the surface against which the coating is dried, in order to prevent adhesion between the shiny metal surface of chrome and the coating composition and the paper, making the chrome-plated metal surface neutral.
Ved fremstillingen av papir med glanset overflate går man vanligvis frem:på den måte at én underlagsbane av papir eller lignende, ved hjelp av kjente metoder, såsom avstrykerblad, valser. ,osv. , bestrykes med en vandig suspensjon som inneholder ett eller flere minérålpigmenter,' såsom kaolin, kalsiumkarbid, satinhvitt, titandiok-syd samt et bindemiddel som kasein eller stivelse eller latex, og mens den belagte flate fremdeles er våt eller fuktig, dvs; formbar, presses den lett mot én oppvarmet polert metalloverf late- i: form av en sylinder eller et endeløst belte,. hvoretter banen tørkes slik at den belagte overflate blir et nøyaktig speilbilde av den overflate som belegget tørkes mot. Papirhanen holdes i kontakt med den polerte overflate lenge nok til at banen.kan trekkes av fra denne uten å briste. In the production of paper with a glossy surface, one usually proceeds: in such a way that one base sheet of paper or the like is rolled using known methods, such as squeegee blades. , etc. , is coated with an aqueous suspension containing one or more mineral pigments, such as kaolin, calcium carbide, satin white, titanium dioxide and a binder such as casein or starch or latex, and while the coated surface is still wet or damp, ie; malleable, it is lightly pressed against one heated polished metal surface let- in: shape of a cylinder or an endless belt,. after which the web is dried so that the coated surface becomes an exact mirror image of the surface against which the coating is dried. The paper tap is kept in contact with the polished surface long enough for the web to be pulled from it without breaking.
Bindemidlets funksjon er å binde pigmentet til underlaget og nedsette beleggets tendens til å klebe til den polerte overflate. Til dette formål kan det også•tilsettes slippmidler. The binder's function is to bind the pigment to the substrate and reduce the coating's tendency to stick to the polished surface. Release agents can also be added for this purpose.
Den belagte og fremdeles fuktige, .dys," fprmbare,, papirbane blir ved hjelp av en gummibelagt valse trykket mot en polert og oppvarmet metalloverflate, som f. eks. en sylinder eller eri endeløs bane. Ved dreining av.denne: overflate- fordunster .vannet'i belegget:, og hår belegget er tilstrekkelig tørt, vil papiret ikke mer klebe til metalloverf laten og løsne av seg selv, slik at papirets overflate gjen-gir et speilbilde av metalloverflaten. Man har imidlertid iakttatt at ved anvendelsen av en forkrommet eller polert metalloverflate har et slikt fremstilt papir en tendens til ikke fullstendig å løsne fra metalloverflaten, idet enkelte beleggspartikler holdes tilbake og kleber til den forkrommede flate med derav følgende nedsatt kvalitet for papiret. The coated and still damp, mistable, paper web is pressed by means of a rubber-coated roller against a polished and heated metal surface, such as a cylinder or an endless web. When turning this: surface evaporation the water in the coating, and if the coating is sufficiently dry, the paper will no longer stick to the metal surface and will detach by itself, so that the surface of the paper reproduces a mirror image of the metal surface. However, it has been observed that when using a chrome-plated or polished metal surface, such produced paper tends not to completely detach from the metal surface, as individual coating particles are held back and adhere to the chrome-plated surface with consequent reduced quality for the paper.
Hensikten med foreliggende oppfinnelse er således å tilveiebringe en fremgangsmåte ved bestrykning av papir eller lignende som fremstilles etter den ovenfor beskrevne fremgangsmåte, hvor man unngår at beleggspartikler. blir klebende fast på en forkrommet eller polert metalloverflate. The purpose of the present invention is thus to provide a method for coating paper or the like which is produced according to the method described above, where coating particles are avoided. becomes sticky on a chrome-plated or polished metal surface.
Det har vært gjort forskjellige forsøk på å oppnå denne hensikt, men uten å oppnå et fullstendig tilfredsstillende resultat. Forutsetningen for en perfekt overflate er altså å oppnå en tilstand for den polerte metalloverflate. som ikke tillater at partikler blir sittende fast. Various attempts have been made to achieve this purpose, but without achieving a completely satisfactory result. The prerequisite for a perfect surface is thus to achieve a condition for the polished metal surface. which does not allow particles to get stuck.
Til dette formål har. man forsøkt å tilveiebringe en nøytra-lisering av den forkrommede metalloverflate, og man har der forsøkt For this purpose have. an attempt has been made to provide a neutralization of the chrome-plated metal surface, and an attempt has been made there
tilsetning av forskjellige' stoffer, såsom oppløselige oljer, benytt- addition of various substances, such as soluble oils, use
else av smøremiddelforbindelser som inneholdt fettede substanser og syntetiserte metallpartikler etc. Else of lubricant compounds which contained greasy substances and synthesized metal particles etc.
Fra U.S." gatent nr. 2.9^3.954 er det kjent en behandlings-metode som utføres i flere trinn, idet det mens fremstillingsmaskinen z står stille påføres en syreoppløsning-på kromflaten. Deretter til-settes for å unngå aktivering av den nøytrale kromflate tributyifos-fat til beleggsammensetningen. From U.S. patent no. 2.9^3.954, a treatment method is known which is carried out in several steps, in that while the production machine z is stationary, an acid solution is applied to the chrome surface. Then, to avoid activation of the neutral chrome surface, tributyphos is added barrel to the coating composition.
Ved foreliggende oppfinnelse oppnås den nøytrale tilstand With the present invention, the neutral state is achieved
for den forkrommede metalloverflate ved periodisk polering av over-flaten ved hjelp av filtskiver som er innsmurt med en pasta bestående av en blanding av kromoksyd og fettstoffer. for the chrome-plated metal surface by periodic polishing of the surface using felt discs that are smeared with a paste consisting of a mixture of chromium oxide and fatty substances.
Fordelene ved foreliggende oppfinnelse i forhold til den The advantages of the present invention in relation to it
metode som er kjent fra U.S. patent nr. 2.9^3.95^ består i at man har en enklere utførelse av selve nøytraliseringen, samtidig som det be-nyttes mindre kompliserte beleggsammensetninger på grunn av fravær av inhibiterende midler. Man unngår dessuten anvendelse av syre i pro-sessen, slik at den fare som dette medfører unngås. method known from the U.S. patent no. 2.9^3.95^ consists in having a simpler execution of the neutralization itself, while at the same time less complicated coating compositions are used due to the absence of inhibiting agents. The use of acid in the process is also avoided, so that the danger this entails is avoided.
Ved å gå frem etter fremgangsmåten ifølge foreliggende oppfinnelse kan således den nøytrale tilstand for den krombelagte overflate oppnås ved en enkel behandling som består i periodisk polering med en blanding av kromoksyd og fettstoffer, som kan utføres mens maskinen står stille. Den periodiske polering utføres etter ca. hO - 50 timers bruk, og man kan herved benytte seg av de tidspunkter hvor maskinen nødvendigvis må stoppes av andre grunner, såsom f. eks. for-andringer i fremstillingen. By proceeding according to the method according to the present invention, the neutral state for the chrome-plated surface can thus be achieved by a simple treatment consisting of periodic polishing with a mixture of chromium oxide and fatty substances, which can be carried out while the machine is stationary. The periodic polishing is carried out after approx. hO - 50 hours of use, and you can thereby make use of the times when the machine must necessarily be stopped for other reasons, such as e.g. pre-changes in the manufacture.
