Description

A kind of Novel coating process units and its application method
Technical field
The invention belongs to coating paper production technical fields, and in particular to a kind of Novel coating process units and its user Method.
Background technique
With being continuously increased for speciality paper demand, speciality paper especially leaching membrane paper in part uses traditional production technology, Because of it not environmentally, difficult recycling and reusing the problems such as, constantly replaced by new production technology.Such as the Chinese of food packaging low grammes per square metre Fort paper mainly using traditional lamination technique because its leaching membrane layer is mostly the polymer such as PE (polyethylene), PP (polypropylene), decompose by hardly possible, The problems such as recycling is difficult, when gradually convenient by new recycling, recycling it is not necessary that high molecular material and paper are first done separating treatment, can be straight It connects and crushes the coating production technology substitution for entering papermaking refining system.
When only having water content to reach 5%-9% the body paper that no bottoming or lamination are handled, it can guarantee the normal use.Contain The problems such as water is too dry lower than 5% paper, papery embrittlement, can occur fibrous fracture after paper stress, picking influences normally to make With.Water content is then overly wet higher than 9% paper, has injustice, scollop, scallop, the problems such as seeping of spreading and sinking in influence normal use.
Traditional paper of the coating production technology processing without bottoming or lamination be broadly divided into unreel, be coated and dried, press polish, Winding, six stages of ageing.For being coated with the product of water-based system, especially lightweight paper product because water suction reason is through drying The problem of fold injustice can occur afterwards.Normally the paper after drying was all dry, and paper could become flat only after press polish It is whole.But the paper wound at this time is although smooth, but can quickly absorb moisture from air because its water content is low when using, and become Uneven and scollop, scallop, influence using.So need by ageing rewetting processing, and be aged rewetting need some months used time or Person 1 year, cycle time was long, inefficiency.
Summary of the invention
In view of the drawbacks of the prior art and insufficient, the present invention is by providing a kind of Novel coating process units and its user Method solves the backwardness of production technology, the technical problem of production cycle length in the prior art, is particularly suitable for the thin paper of 20-80gsm On.
To achieve the above object, the technical solution of the present invention is as follows:

Further, steam steam discharge cover, the row of being equipped on the steam steam discharge cover are installed above the steam showers case Gas blower and exhaust duct.
Preferably, steam showers bottom portion is also equipped with the regulating mechanism for adjusting steam discharge rate;The steam Boiler is one of commercially available oil-fired steam boiler or gas-steam boiler.
Preferably, the thermal finalization system includes the gentle dynamic pressure roller I of setting roller;The outlet end one of the steam showers case Side is equipped with deflector roll III, handles the coating paper completed through steam showers system for accepting, the coating paper passes through on setting roller It is connected after pneumatic pressure roller I pressing with chilling roller cooling system;Be also connected on the setting roller the hot die heater of oil and for Coating line realizes synchronous rotating electric machine.
Preferably, the chilling roller cooling system includes the gentle dynamic pressure roller II of chill roll, and one end of the pneumatic pressure roller I is used for It accepts and handles the coating paper completed through thermal finalization system, the other end is connected with chill roll;The chill roll is externally connected with cold water Unit is equipped with pneumatic pressure roller II on the chill roll.
Preferably, the present invention also provides the application method of the Novel coating process units, following step is specifically included It is rapid:
(a) steam showers: the coating paper through being dried is led by deflector roll I from the opening of the side bottom end of steam showers case Enter at roller II, the vapor then sprayed at the bar shaped tuyere through bottom end carries out squirting processing;
(b) thermal finalization: it is hot fixed that the coating paper handled through step (a) steam showers is carried out by deflector roll III into setting roller Type, setting roller make coating paper become smooth after the hot die heater heating of commercially available oil in such a way that pneumatic pressure roller I is pressed, Water content controlling coating paper by way of controlling the temperature of setting roller.
(c) cooling: the coating paper handled through step (b) thermal finalization is entered in chill roll by pneumatic pressure roller I, by pneumatic The mode that pressure roller II is pressed makes coating paper cool down;The temperature of chill roll is controlled by commercially available water cooler to make coating paper Reach the temperature of requirement, final paper after cooling is connected through deflector roll IV with winding section.
Preferably, in step (b), the water content controlling coating paper by way of controlling the temperature of setting roller reaches 5%-9%.
Preferably, in step (c), by the temperature of water cooler control chill roll to make coating paper reach the temperature of requirement Degree, final temperature reach 20 DEG C -30 DEG C of ambient temperature, cooling effect can be realized.
Further, the present invention also provides a kind of Novel coating production technologies, specifically includes the following steps:
(1) it unreels;
