The invention relates to the technical field of mobile phone film sticking devices, in particular to a simple mobile phone film sticking device. The technical problem to be solved by the present invention is that it is inconvenient to carry out cleaning and film sticking at the same time in the existing mobile phone film sticking device. In order to solve the above technical problems, the present invention provides a simple mobile phone film applicator, which includes a support plate, a seesaw is connected to one side of the support plate, and clip bars are fixedly connected to both sides of the top of the support plate, and The opposite sides of the two clips are provided with notches, and the top of the clips is provided with a moving groove communicating with the notch, and a moving shaft is inserted in the moving groove, and the bottom end of the moving shaft is fixedly connected with a Tablet. In this invention, the adhesive ring on the roller is placed on the screen of the mobile phone, the film is inserted into the notch between the two clips, the supporting plate is pulled, and the film is pushed. At this time, the film is closely behind the adhesive ring. After one place of the adhesive ring is cleaned, the adhesive layer of the adhesive film is just glued on because the adhesive film is in a tilted state.

The invention discloses a method for slenderizing and permanently shaping uncolored wool. The method adopts the scheme comprising the following steps of carding, preprocessing, twisting, slenderizing, shaping, untwisting, oxidizing, washing, drying and winding the uncolored wool with the fineness of 14.5 to 27.5mum in the form of wool tops to obtain the permanently shaped wool with the fineness of 12.5 to 22.5mum. The method has the advantages of simple process and high production efficiency, the obtained slenderized wool has silky luster and hand feeling, the fineness, the dispersion rate and the short-haired rate of the wool are equivalent to those of ordinary wool with the same fineness, and the fiber strength of the wool is improved by 20% in comparison with that of the ordinary wool with the same fineness.

The invention discloses a biomodification method of lactic acid fiber with good spinnability, which is prepared by the following method: adding various raw materials into a high-speed mixer, and dispersing at high speed to obtain a modified polylactic acid mixture; uniformly mixing The modified polylactic acid mixture is melt blended and extruded through a twin-screw extruder to obtain a modified polylactic acid masterbatch, and vacuum dried; the modified polylactic acid functional masterbatch chips and vacuum dried ordinary polylactic acid chips are put into high-speed mixing The mixture is evenly mixed in the machine, and the mixture is spun on a melt spinning machine through circular spinneret holes to obtain modified polylactic acid fibers, and then undergoes microbial modification and strictly controls the fermentation parameters. Different from ordinary constant temperature fermentation, certain instantaneous heat treatment is adopted. The purpose of shortening the fermentation time and obtaining an unexpected modification effect can be achieved.

The invention discloses a stone surface protective nano-coating, which comprises the following formula (parts by weight): 24-26 nanometer silicon dioxide; 24-26 butanol; 4.5-5.5 butyl acetate; 4.5; ethyl carbamate 2.5~3.5; methyl methacrylate 1.5~2.5; acrylic acid 14.5~15.5; butyl acrylate 5.5~6.5; hydroxyethyl acrylate 6.5~7.5; Ethylene glycol monobutyl ether 3.5~4.5. The invention also discloses a process for preparing the stone surface protective nano coating. The coating can be applied to the surface protection of various stone products such as building interior and exterior walls, stone floors, stone guardrails, and stone countertops. At room temperature, it can penetrate deeply into the surface of the stone, forming a dense, transparent, hard protective film on the surface of the stone, preventing various diseases of the stone, and improving the fullness, color saturation, texture, permeability and surface of the stone itself. Hardness and has the ability of easy cleaning and stain resistance.

The invention provides a reactive dyeing method for pearl viscose fibers. The reactive dyeing method mainly comprises the following steps of: dyeing, wherein reactive dyes, sodium carbonate and sodium sulfate are added in water to form dye liquor, pearl viscose fiber fabric is put into the dye liquor after the dye liquor is heated to be at a temperature ranging from 50 DEG C to 60 DEG C, the liquor ratio equals to (25-30):1, the pH of the dye liquor equals to 6 to 7.5, and then the dye liquor is heated continually to reach a temperature ranging from 70 DEG C to 100 DEG C and is kept at the temperature for 80 minutes to 100 minutes, thereby dyeing the fabric; washing the dyed fabric till the fabric is neutral; and drying the fabric. According to the dyeing method, the composition and component proportion of the dye liquor are optimized, the parameters of the dyeing process are adjusted, the dyeing is easy, and the dye-uptake and color fastness of the pearl viscose fibers are improved.

The invention provides natural bamboo fiber shirt fabric which has silky gloss, good feel and drapability, and is rich in graceful feeling, antibiosis, moisture-adsorption and ventilating. Warps and wefts of the fabric are both natural fiber / bamboo viscose blended yarns, the blending ratio of the warps and the wefts is 1:1, the warp density is 512 / 10cm, and the weft density is 338.5 / 10cm. A manufacture method of the natural bamboo fiber shirt fabric comprises the following steps: a, blending: opening picking, carding cotton, drawing out, roving and spun yarn; b, drum yarn dying: tube loosening, pretreatment, dying, dehydration and drying, wherein the pretreatment comprises bleaching and enzyme treatment; during bleaching: soda ash is 1-3g / L, hydrogen peroxide is 1-2g / L, the temperature is 95 DEG C, the time is 35-45min; and during the enzyme treatment, HontonezymePA is 1-1.5g / L, pH value is 4.5-5.5, the bath ratio is 1:15, and the time is 25-35min; and during dying, the drum yarn density is 0.33-0.35g / cm<3>, and MegafixB type reactive dying is adopted; c, weaving: winding, warp pulp connection, drawing in or warp tying and weaving; and d, after treatment: singeing, desizing, sizing and preshrinking.

A method of forming a composite door is disclosed. The method comprises: mixing together a thermoplastic polymer with an organic fibrous material in a ratio such that the organic fibrous material constitutes 40 to 60 percent by weight of the mixture; extruding the mixture under heat and pressure to create a thin sheet form; cutting the sheet to a predetermined size; removing material from at least one surface of the sheet to create a homogeneous appearance devoid of obvious fibrous particles; thermoforming the sheet to impart to the at least one surface an exterior three dimensional door surface to create a thin door facing; and assembling two of the thermoformed thin door facings, a peripheral frame and a core material into a door.
