The crucible is discharged from the raw material, and the wet web is formed on the I mesh, and the web is further dehydrated and dried in the dry section of the paper machine. The wood typically introduces a retentate into the feedstock which increases the adsorption of particles such as fine particles and filler particles onto the cellulosic fibers so that they are retained by the fibers on the web. A wide variety of retention agents are known in the art, and examples thereof include anionic, nonionic, amphoteric and cationic organic polymers, inorganic materials, and combinations thereof, of different knives. Due to incomplete retention, the water obtained by dewatering the raw material and the wet paper web, referred to as white water, contains fine particles that are not retained on the crucible network, and the white water is usually transported in different flow circuits. In a paper machine with a dilute headbox, white water is used to dilute the material in the pre-net phase. Thereby, the high-copper fluid is diluted with a low-consistency fluid derived from white water. The headbox has a series of mixing sections or dilution lines distributed over the wide compartment of the 1278555 front box. /, ^ ^. The water system is injected into the mixing section to locally control the dilution of the raw material, and the coarse IV JT^L> 9 > becomes a variable consistency profile which is opened at a fixed volumetric flow rate.兮乂 4 ° Hai Diluted Grid Box Design provides a comparison of paper characteristics, hunting adjustment dilution f, that is, the ratio of the consistency fluid to the low consistency fluid at the fixed point of the dip net front box of II; It can be improved:: the basis weight of the paper web, and the cost uniformity in the transverse machine direction: , and obviously 'when using high-performance retention agent, the papermaking method has been experienced and the method has been produced. The paper characteristics are still not fully satisfactory and have been attributed to improper Piteh deposition control. Among the various papers in the placket, the problems caused by the accumulation of wood asphalt on the paper machine and the formation of the final paper and the main moon have been recognized. Wood asphalt generally refers to an emulsified hydrophobic organic compound. Wood asphalt can be defined as a viscous, resinous material that is released from the wood during the mashing process. Wood asphalt Φ includes viscous materials originating from coated waste paper and recycled (four) fibers, such as additives, and is often referred to as glue or glue. In papermaking, water, wood asphalt is unstable, A colloidal suspension of hydrophobic particles is present. Thus, typical papermaking process conditions, such as hydrodynamic and mechanical shear forces, as well as drastic changes in temperature and chemical environment and balance, may cause colloidal wood adchlorite particles to cohere or deposit in cellulosic suspensions. On the surface of the device. This can result in quality defects in the finished product, such as the formation of dots or holes and poor quality paper surfaces, as well as reduced equipment life, operational time, paper machine downtime, and ultimately lost paper mill profits. In paper mills with high-content process water closure, such as large white water cycles, this problem is magnified. 1278555 SUMMARY OF THE INVENTION The present invention is generally directed to a method of making paper comprising: (i) providing a primary water stream comprising cellulose fibers; (ii) introducing one or more retention components into the main water stream to form a main stream comprising one or more retentate components; (111) providing a dilution water stream; (iv) introducing a low molecular weight cationic organic polymer into the dilution water stream to form a dilution comprising a low molecular weight cationic organic polymer The water stream 'the low molecular weight cationic organic polymer has a weight average molecular weight of up to 5, 〇〇〇, 〇〇〇; (v) the dilution water containing the low molecular weight cationic organic polymer flows into the main component of A 3 with one or more retention components The water stream is formed to form a generated water stream; and then (v 1 ) the child-generated water stream is sprayed onto the crucible network and the resultant water stream is dewatered to form a web. Ben Maoming is more directed to a method of making paper on a paper machine containing a #release net front box, comprising:

Unless otherwise indicated, parts and % are: two parts by weight and % by weight. [Embodiment] The method of the present invention was carried out by using 1 different LMW cationic organic polymer as an additive for the LC raw material 24 1278555. On a paper machine using a dilution head box to produce an sc-stage, the paper is made from a cellulosic suspension. Retention agent is added to the HC raw material; first 8 kg, which is based on a dry product of dimethylamine-epichlorohydrin copolymer having a weight average molecular weight of about 10,000 per ton, and then 36 kg, It is based on a cationic polyacrylamide having a weight average molecular weight of about 4.6 million per ton. The Lc raw material is obtained by draining the raw material. 500 ml of LC material was added to a power drain tank and mixed at 1000 ppm for 15 seconds, and then the LMW cationic organic polymer material was mixed and mixed for 30 seconds. For the blank test, the feedstock was added to a power drain and mixed at 1 Torr for 45 seconds without the addition of LMW cationic organic polymer. The obtained raw material was then drained, and the filtrate was collected to pass through a 1 micron filter. The uv absorbance was measured using a 〇cean Optics S2000 UV spectrophotometer with a fast scan rate as a representation of the wood pitch content of the treated portion. At the same dry dose (about 4 kg/ton based on dry matter of LC raw material, corresponding to about 2 kg/ton based on the total dry matter volume tonnage). LMW-1 is a dimethylamine-epichlorohydrin copolymer having a weight average molecular weight of about 12 〇, 〇〇〇; LMW-2 is a ruthenium having a weight average molecular weight of about 1 〇〇〇, 〇〇〇 a base amine-epichlorohydrin copolymer; LMW-3 is a polydiallyldimethylammonium vaporate having a weight average molecular weight of about 680, 〇〇〇; and LMW-4 is a weight average molecular weight of about 18 〇〇, 聚 Poly 25 1278555 Diallyldimethylammonium hydride.
