Abstract
An acid-resisting sewing thread for a dedusting cloth bag is formed by twisting and connecting alkali-free glass fiber yarns and modified polyethylene fang oxadiazoles fiber yarns in parallel, polytef mixed solvent are coated on the surface of the twisted sewing thread through a coating processor, so that a polytef membrane with the thickness of less than or equal to 1 mm and taking polytef as the main content is coated on the surface of the sewing thread. The alkali-free glass fiber yarns are 8-strand and 80-branch alkali-free glass fiber yarns, the modified polyethylene fang oxadiazoles fiber yarns are 8-strand and 80-branch modified polyethylene fang oxadiazoles fiber yarns, and the polytef mixed solvent is a mixture of the polytef emulsion, epoxy modified silicon softening agent, silane coupling agent and water. The acid-resisting sewing thread for the dedusting cloth bag has the beneficial effects that as the alkali-free glass fiber yarns and the modified polyethylene fang oxadiazoles fiber yarns are adopted, the acid-resisting sewing thread has good fire resistance; due to the polytef membrane coated on the surface, the acid-proof and alkaline-proof performances are added, thereby meeting the requirement on manufacturing industrial dedusting cloth bags for high-temperature flue gas filtering industries.
Description
Technical field
The utility model belongs to industrial dedusting cloth bag weaving manufacturing technology field, specially refers to a kind of dust-removal cloth-bag and uses acidproof sewing line.
Background technology
In existing techniques; The process industry dust-removal cloth-bag all uses glass fibre cladded yarn line usually, be a kind of be yarn core with the glass fibre, outsourcing staple fibre and the yarn that is spun into; Have the advantage of filament of glass fiber and outsourcing staple fibre concurrently, make the resultant yarn performance surpass single fiber.Yarn core glass fibre commonly used has alkali-free glass fibre etc., outsourcing staple fibre fire-retardant fine polyvinyl chloride fibre staple fibre, fire retardant viscose short filament and nylon staple commonly used etc.Be mainly used in industrial dedusting cloth bag weaving manufacturing at present and make sewing thread.But glass fibre cladded yarn line (or lining and fabric of being woven into by composite yarn) runs into bad working environments such as soda acid or lasting superhigh temperature, and the distortion of will wearing out can't be used, and brings serious inconvenience and loss to production.
The utility model content
Glass fibre cladded yarn line is prone to aging shortcoming of being out of shape in the prior art in order to overcome, and the purpose of the utility model provides a kind of dust-removal cloth-bag and uses acidproof sewing line.
The technology side that the utility model adopted decides on a verdict and is:
A kind of dust-removal cloth-bag is used acidproof sewing line; Gather fragrant oxadiazoles silvalin parallel connection, twist and form by alkali-free glass fibre yarn, modification; The sewing line surface of twisting with the fingers; At its surface-coated polytetrafluoroethylene (PTFE) mixed solvent, making the surface of sewing line coat thickness is the main component poly tetrafluoroethylene with the polytetrafluoroethylene (PTFE) for≤1mm through the coating processor.
Described alkali-free glass fibre yarn be 8 bursts of 80 alkali-free glass fibre yarns, described modifications to gather fragrant oxadiazoles silvalin be that 8 bursts of 80 modifications gather fragrant oxadiazoles silvalin, described polytetrafluoroethylene (PTFE) mixed solvent is the intermixture of ptfe emulsion, epoxy modified silicone softener, silane coupler and water.
Described alkali-free glass fibre yarn has anti-flammability preferably, and described modification gathers fragrant oxadiazoles silvalin, is high-quality heat-resistance and flame-retardant fiber.Have good heat endurance, chemical stability and electrical insulating property as the flame-resistant high-temperature-resistant material, occupy leading role in essential fire resistance fibre field.Described polytetrafluoroethylene (PTFE) mixed solvent overlay film has acid-proof alkaline.
The beneficial effect of the utility model is: owing to adopt alkali-free glass fibre yarn and modification to gather fragrant oxadiazoles silvalin; Has anti-flammability preferably; Thereby improved the resistance to elevated temperatures of filtering material effectively; Be coated on the acid-proof alkaline that with polytetrafluoroethylene (PTFE) for main component poly tetrafluoroethylene increased product of surface thickness, satisfied needs for fume high-temperature filtration industry process industry dust-removal cloth-bag for≤1mm.
Description of drawings
Fig. 1 is the structural representation of the utility model.
In Fig. 1: 1-alkali-free glass fibre yarn, 2-modification gather fragrant oxadiazoles silvalin, 3-poly tetrafluoroethylene.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further explanation.
The following stated is merely the preferred embodiment of the utility model, does not therefore limit the protection domain of the utility model.
The utility model provides a kind of dust-removal cloth-bag to use acidproof sewing line, and in structural representation shown in Figure 1: alkali-free glass fibre yarn 1, modification gather fragrant oxadiazoles silvalin 2, poly tetrafluoroethylene 3.
Embodiment 1
1,80 alkali-free glass fibre silks of sub-thread and 80 modifications of sub-thread being gathered fragrant oxadiazoles filament moves back respectively to separate and merges into 8 strands of alkali-free glass fibre yarns 1 and 8 share reform property are gathered fragrant oxadiazoles silvalin 2;
2, more above-mentioned two kinds of 8 strands of alkali-free glass fibre yarns 1 and 8 share reform property are gathered fragrant oxadiazoles silvalin 2 and on twisting mill, carry out parallel connection, twisting, moulding, obtaining 16 strands 80, twisting with the fingers to S, the twist is the semi-finished product sewing line about 220/10cm;
3, with the speed of above-mentioned semi-finished product sewing line with 2m/min; After submergence is formed solution tank through ptfe emulsion, epoxy modified silicone softener, silane coupler and water; Be " returning " word drying oven oven dry of 3 meters again through length; Form thickness for≤1mm be main component poly tetrafluoroethylene 3 with the polytetrafluoroethylene (PTFE), through winder rolling moulding.
Claims (2)
1. a dust-removal cloth-bag is used acidproof sewing line, comprises that alkali-free glass fibre yarn, modification gather fragrant oxadiazoles silvalin, is characterized in that: the sewing line surface applies poly tetrafluoroethylene.
2. a kind of dust-removal cloth-bag according to claim 1 is used acidproof sewing line, it is characterized in that the thickness that applies poly tetrafluoroethylene is≤1mm on the sewing line surface.
