Description

On-line method is produced the process units of New-type long-acting drip functional greenhouse film

Relate to the field

The utility model belongs to the continuous process units of on-line method, specifically, is the process units that a kind of on-line method is produced New-type long-acting drip functional greenhouse film.

Background technology

By consulting pertinent literature, external as Japan adopts the method development and production long-acting anti-dropping functional membrane of outer spray stream dropping liquid, and the prescription of its drip liquid carried out the patent registration, only external application pattern is introduced in the document, comprise multiple modes such as dip-coating, showering, roller coat, the production technology of Japan adopts " two-step method ", promptly carries out the blowing of film earlier, and then carries out surface treatment, coating, oven dry.The volume type.

The surface treatment of domestic because super wide cut macromolecular material and in large tracts of land, at a high speed, achieve no breakthrough on the continuous paint-on technique, and can satisfy industrial special equipment and also fail to succeed in developing, thereby, add the function additive method in generally adopting and produce the drip functional membrane, the drip lasting period only has 4～6 months.Domestic the spary coating type drip agent is studied, its product is to build the method that the secondary spraying is adopted in the back, technological operation complexity in the canopy chamber, specification requirement is higher, the quality instability, and the drip lasting period also only have about 6 months, and fog is big in the canopy, has a strong impact on crop growth.

Technology contents

The purpose of this utility model be to provide a kind of drip lasting period can 〉=612 months and effectively solve the process units that on-line method that on-line method sprays problems such as production Technology difficulty is outward produced New-type long-acting drip functional greenhouse film.

The utility model is achieved in that and comprises nip rolls 1, collapser 2, hopper 3, extruder 4, mouthful mould 5, air blast 6, deflector roll 7, corona treatment 8, coating groove 9, drier 10, winder 11, hopper 3, extruder 4, mouthful mould 5, air blast 6 connect successively, there is nip rolls 1 end of deflector roll 7, nip rolls has collapser 21 time, on the connecting line of deflector roll 7 corona treatment 8, coating groove 9, winder 11 is arranged successively.

Advantage of the present utility model is: functional membrane has pliability and ageing-resistant performance, can cover continuously more than 12 months; The electric discharge surface treatment technology is adopted in the surface treatment of plastics, and handling width is 5 meters, and surface tension 40～44 dyne, electric spark treating apparatus are the treatment facility of present domestic maximum; Coating method adopts the dip-coating technology, to guarantee the drip lasting effect; By film surface is dried, guarantee the enough bonding strengths that has between the coat of film surface and the film, to guarantee the drip lasting effect; This technology is the on-line method continuous production processes, by speed ring closed-loop path design to extruded velocity, hauling speed, electric spark processing speed, second traction speed, draw off rate, avoided plastic sheeting generation stretching being influenced product quality, guaranteed the product quality of functional membrane owing to velocity gradient changes.

Accompanying drawing 2 is the production technology flow chart.

Concrete enforcement

As shown in Figure 1, mainly form by nip rolls 1, collapser 2, hopper 3, extruder 4, mouthful mould 5, air blast 6, deflector roll 7, corona treatment 8, coating groove 9, drier 10, winder 11 etc., hopper 3, extruder 4, mouthful mould 5, air blast 6 connect successively, there is nip rolls 1 end of deflector roll 7, nip rolls has collapser 21 time, on the connecting line of deflector roll 7 corona treatment 8, coating groove 9, winder 11 is arranged successively.

As shown in Figure 2, the utility model is in film factory of company of orchidization HTC, rely on former three layers of composite membrane unit to design and produce second traction equipment and transfer roller device, electric spark treatment facility, impregnating equipment, drying plant voluntarily, realized technological process and technology that " on-line method " produces New-type long-acting drip functional greenhouse film.

Second traction equipment and transfer roller device, the film of extruder through once pulling out is sent to the electric spark treatment facility through transfer roller again, film is through applying behind air knife control coating thickness through dipping tank after the surface treatment again, be sent to drying unit and carry out the oven dry of film surface coating liquid, be sent to taking-up equipment through second traction again, finish a complete set of technical process.In order to ensure in process of production film transmit stablize, avoid film produces fold, side seam is pressed and, once traction, electric spark processing speed, second traction adopt the design of speed ring closed-loop path.

The New-type long-acting drip functional membrane product that adopts the utility model technology development trial production on August 15,1 day to 2000 February in 1999 in the Jiangsu Province Agriculture Science Institute, detain the canopy experiment on August 25,15 days to 2000 February in 1999 respectively in Gansu Province's agricultural technology extension master station agricultural experiment base, antidrip phase 〉=18 month.And again respectively at having carried out demonstration test in Xigu District agrotechnical station Zhang Jiatai township, Lanzhou in November, 2000, by on March 20th, 2002, used 16 months, the drip effect is still remarkable, and it is obvious to subtract fog effect, and temperature is than using other plastics cladding materials can improve 2～3 ℃ of temperature in the greenhouse.
