Bending-resistant steaming pad

Abstract: The invention discloses a bending-resistant steaming pad The bending-resistant steaming pad comprises modified sisal hemp fiber cloth and a mixed silica gel layer wrapping the surface of the modified sisal hemp fiber cloth The mixture silica gel layer is prepared from, by weight, 80-120 parts of polydimethylsiloxane, 10-20 parts of gaseous phase silicon dioxide, 5-7 parts of epoxy soybean oil, 1-3 parts of tea tree oil, 001-005 part of platinum catalyst and 2-4 parts of paraffin oil In the preparation process of the modified sisal hemp fiber cloth, a sodium hydroxide aqueous solution is obtained, temperature is adjusted, sisal hemp fiber cloth is added, soaked and washed with water to remove sodium hydroxide, and a material A is obtained after drying; glycolide and methylbenzene are evenly mixed, in the nitrogen atmosphere, temperature is adjusted, the material A is added, soaking and temperature raising are conducted, stannous octoate is added dropwise, reflux and cooling are conducted, the material An obtained after reflux is obtained and washed, and the modified sisal hemp fiber cloth is obtained after air drying The bending-resistant steaming pad is resistant to high temperature, resistant to bacteria, good in bending resistance and high in impact resistance

Preparation method and application of hyperbranched biphenyls liquid crystal grafting sisal hemp microcrystal

Abstract: The invention discloses a preparation method and an application of a hyperbranched biphenyls liquid crystal grafting sisal hemp microcrystal. The preparation method comprises the steps of carrying out surface modification on sisal hemp microcrystal by utilizing a silane coupling agent, dispersing the modified sisal hemp microcrystal into N-methyl pyrrolidinone, adding 3,5-diaminobenzoic acid, pyridine and triphenyl phosphate, reacting for 3 to 5 hours at the temperature of 90 to 120 DEG C under the protection of N2, cooling to the room temperature, then pouring the obtained product from the former step into a methyl alcohol solution, precipitating, filtering, washing, drying in a vacuum drying oven to constant weight, dissolving in N-methyl pyrrolidinone, adding an organic tin catalyst, adding methylbenzene-2,4-diisocyanate under the protection of N2, reacting for 5 to 7 hours at the temperature of 80 to 100 DEG C, then adding 4,4'-bi(beta-hydroxyethoxy) biphenyl, reacting for 10 to 12 hours, cooling to the room temperature, filtering and washing, and drying in the vacuum drying oven to constant weight, thereby obtaining the hyperbranched biphenyls liquid crystal grafting sisal hemp microcrystal which is applied to a modified epoxy resin composite material. The method is simple in process, convenient to operate, easy to disperse, good in directivity and capable of remarkably improving the performance of the composite material.

Residue-juice separation production line for sisal hemp leaves

Abstract: The invention discloses a residue-juice separation production line for sisal hemp leaves. The residue-juice separation production line comprises a residue squeezing machine which is connected with a discharging port of a sisal hemp leaf fiber extractor through a leaf pulp scrap conveying belt, and the leaf pulp scrap conveying belt conveys leaf pulp obtained after fiber extraction by the sisal hemp leaf fiber extractor into a feeding pipe of the residue squeezing machine; the leaf pulp scrap conveying belt is sequentially provided with a residue fishing roller and a fiber smashing device in the conveying direction of leaf pulp; a juice collection groove is formed below the sisal hemp leaf fiber extractor and the conveying belt, and sisal hemp juice generated in the fiber extraction processof the sisal hemp leaf fiber extractor, sisal hemp juice dropping in the process that the conveying belt conveys the sisal hemp leaf pulp and sisal hemp juice squeezed out by the residue squeezing machine fall into the juice collection groove separately. As is seen from the structures, the residue-juice separation production line for the sisal hemp leaves makes residues of the sisal hemp leaf pulp separated from the juice of the sisal hemp leaf pulp through the working procedures of residue fishing, fiber smashing, residue squeezing and the like on the leaf pulp scraps after fiber extraction,the residue and juice are recycled after being collected separately, and the utilization rate of the sisal hemp leaves is increased accordingly.
