History of Paper Pulp

admin — Sat, 25 Jul 2009 03:23:59 +0000

Using wood to make paper is a fairly recent innovation. In the 1800s, fiber crops such as linen fibres were the primary material source, and paper was a relatively expensive commodity. The use of wood to make pulp for paper began with the development of mechanical pulping in Germany by F.G. Keller in the 1840s, and by the Canadian inventor Charles Fenerty in Nova Scotia. Chemical processes quickly followed, first with J. Roth’s use of sulfurous acid to treat wood, followed by B. Tilghman’s US patent on the use of calcium bisulfite, Ca(HSO3)2, to pulp wood in 1867.

Almost a decade later the first commercial sulfite pulp mill was built in Sweden. It used magnesium as the counter ion and was based on work by Carl Daniel Ekman. By 1900 sulfite pulping had become the dominant means of producing wood pulp, surpassing mechanical pulping methods. The competing chemical pulping process, the sulfate or kraft process was developed by Carl F. Dahl in 1879 and the first kraft mill started (in Sweden) in 1890.

The invention of the recovery boiler by G.H. Tomlinson in the early 1930s allowed kraft mills to recycle almost all of their pulping chemicals. This, along with the ability of the kraft process to accept a wider variety of types of wood and produce stronger fibers made the kraft process the dominant pulping process starting in the 1940s.

Global production of wood pulp in 2006 was 160 million tonnes (175 million tons). In the previous year, 57 million tonnes (63 million tons) of market pulp (not made into paper in the same facility) was sold, with Canada being the largest source at 21% of the total, followed by the US at 16%. Chemical pulp made up 93% of market pulp.

Kraft process

admin — Sat, 18 Jul 2009 04:00:07 +0000

The kraft process (also known as kraft pulping or sulfate process) describes a technology for conversion of wood into wood pulp consisting of almost pure cellulose fibers. The process entails treatment of wood chips with a mixture of sodium hydroxide and sodium sulfide that break the bonds that link lignin to the cellulose. The process name is derived from German kraft, meaning strength/power; both capitalized and lowercase names (Kraft process and kraft process) appear in the literature, but “kraft” is most commonly used in the pulp and paper industry.

Industrial papermaking

admin — Thu, 04 Jun 2009 02:39:27 +0000

A modern paper mill is divided into several sections, roughly corresponding to the processes involved in making hand-made paper. Pulp is refined and mixed in water with other additives to make a pulp slurry, the headbox of the papermachine (Fourdrinier machine) distributes the slurry onto a moving continuous screen, water drains from the slurry (by gravity or under vacuum), the wet paper sheet goes through presses and driers and is finally rolled into large rolls, often weighing several tons.

Another type of papermachine makes use of a cylinder mold that rotates while partially immersed in a vat of dilute pulp. The pulp is picked up by the wire and covers the mold as it rises out of the vat. A couch roller is pressed against the mold to smooth out the pulp, and picks the wet sheet off of the mold

Papermaking

Papermaking is the process of making paper, a substance which is used ubiquitously today for writing and packaging.

In papermaking a dilute suspension of fibers in water is drained through a screen, so that a mat of randomly interwoven fibers is laid down. Water is removed from this mat of fibers by pressing and drying to make paper. Most paper is made from wood pulp, but other fiber sources such as cotton and textiles may be used.

What is paper?

The word paper is derives from the word papyrus and is a substance composed interlaced into a compact web, which can then be macerated into pulp, dried and pressed.
Today, paper includes a wide range of products with very different applications: communication, cultural, educational, artistic, hygenic, sanitary as well as for storage and transportaion of all kinds of goods. It is almost impossible to imagine a life without paper.

Base Paper vs Converting

admin — Sat, 08 Mar 2008 01:53:26 +0000

As you can see, in this website we have 2 main categories, base paper and converting. What is the difference you say?
Well. here goes… Ekamas Fortuna uses scrap or waste paper as the base material for base paper. These scrap or waste paper are processed to make Kraft liner, B Kraft, Medium liner, Chipboard, Coreboard, etc.. It has a different thickness, smoothness and color. Customers will receive their orders in rolls or perhaps sheet
While base paper itself is the base material for converting/converted paper. Through a certain process, it is transformed into different shape such as paper cone, seamless paper core/tube or even shopping bag. It’s more flexible in size and thickness, it depends on the customer’s specifications. You see? If you have any question, don’t hesitate to contact us. Ekamas Fortuna welcomes You…

What is paper core?

Paper core is a hollow cylindrical object that paper, thread or fabrics are wound around to form a roll. They are made of thick sturdy cardboard. The thickness of its walls will vary according to the type and amount of product that will be wound on it. Ekamas Fortuna, also produced paper core with vary thickness and size according to specifications provided by customer. Please contact us for further details of our products

Kraft Paper

Have you ever wonder what kraft paper is? Well, kraft paper is paper produces by the Kraft process from wood pulp. It is strong and relatively coarse. Kraft paper is usually a brown color but can be bleached to produce white paper. It is used for paper grocery bags, multiwall sacks, envelopes and other packaging (source:wikipedia)

What about us ? Well, beside kraft liner, ekamas fortuna also produced medium liner 125g/m2, 150g/m2, 200g/m2

You could set your “about page” to be the entry point or maybe your site’s colophon. You might even do something a bit more dynamic and set a custom page that shows a list of the latest comments, posts, categories and archives.
