Embodiment 1
[0022] Example 1: Use a three-layer blow molding agricultural film unit to produce an agricultural film with a width of 7 meters and a thickness of 0.08mm, and an inner layer of a light-effect hybrid film:
[0023] Common blown film processes are known. According to the anti-aging formula:
[0024] Polyethylene film 100m 2
[0025] Coupling agent 0.1-0.3g
[0026] Antistatic agent 0.1-0.2g
[0027] Silica sol 7-12g
[0028] Titanium dioxide sol 7-12g
[0029] Distilled water 200-1000g
[0030] First dissolve the titanium dioxide sol into the distilled water, and stir evenly; then dissolve the silica sol into the aforementioned solution, and stir evenly; dissolve the coupling agent and antistatic agent into the aforementioned solution, stir evenly, and then inject the compounded solution into the In the stainless steel container, use a high-pressure pump with a pressure ≥ 8 MP to inject into the rotary splitter through precise metering; spray in the film bubble through a...
Embodiment 2
[0031] Embodiment 2: Produce 7 meters wide 0.08mm thick with three-layer blow molding agricultural film unit, the outer layer prepares surface light-grafted film shed film:
[0032] Common blown film processes are known. According to the anti-aging formula:
[0033] Polyethylene film 100m 2
[0034] Cationic surfactant 0.1-0.3g
[0035] Acrylic microemulsion 1-2g
[0036] Photosensitizer 0.1-0.3g
[0037] Silica sol 7-12g
[0038] Titanium dioxide sol 7-12g
[0039] Distilled water 200-1000g
[0040]First dissolve titanium dioxide sol into distilled water, and stir evenly; then dissolve silica sol into the aforementioned solution, and stir evenly; then dissolve cationic surfactant, acrylic emulsion, and photosensitizer into the aforementioned solution, compound them together, and stir evenly. Then inject the compounded solution into the stainless steel barrel, and use a liquid pump with a pressure ≥ 10MP to inject it into the fixed splitter through precise metering; sp...
Embodiment 3
[0041] Embodiment 3: with the rolled blown film that has been sprayed, double-layer prepares blown film photocatalyst interface molecular film:
[0042] Get the photografted polyethylene film sprayed through example 2:
[0043] Polyethylene film 100m 2
[0044] Antistatic agent 0.1-0.3g
[0045] Silica sol 7-12g
[0046] Distilled water 200-1000g
[0047] Stir the silica sol with distilled water first, then compound the antistatic agent together and stir evenly. Then inject the prepared liquid into a liquid tank; place the single roll of film that has been made on the driven roller to release the film, and put the photografted film into the liquid tank through the unrolling device for soaking treatment, so that the light The surface layer of the grafted polyethylene film is dip-coated with an antistatic coating; then the film is introduced into the dryer through a guide roller, and the finished product is made by a winding or folding device. While possessing the film eff...
