Glass reinforced plastics twines lay aside canister to produce craft and good integral performance specially to wait for an industry to having broad market in 2 chemical industry, anticorrosive, water with its. As a result of all sorts of reasons, canister of lay aside of glass reinforced plastics is put in the quality problem with particular move in use process, among them the commonnest is leakage of lay aside canister. Article union production is actual, according to the machine program of canister of lay aside of glass reinforced plastics, the reason of a few respects that twines leakage of lay aside canister with respect to glass reinforced plastics undertakes analytic discussion, in order to achieve control and the occurrence that reduce leakage, raise the goal of product quality.
Of 1 raw material choose
The select material that glass reinforced plastics twines lay aside canister must appropriate, select material should hold to quality the principle of price of preferential, give attention to two or morethings. The structure of coal tub wall that twines lay aside canister in the glass reinforced plastics in actual production is liner layer, intensity layer and outside layer commonly. Because each motive is different, choose in material go up to have each different, liner layer is contacted with medium directly, its material choice is right, the leakage that twines lay aside canister to control is having crucial effect. Medium of acidity of keep in storage chooses vinyl colophony normally, be like MFE, 1, MFE, 2. Alkalescent medium uses reserve double phenolic A colophony, be like 197# colophony. Canister of requirement lay aside is able to bear or endure water suggests to be like,be used 189# colophony. Alkali resistance of canister of requirement lay aside, be able to bear or endure water is used without alkaline Bo fine, acid-proof in using alkaline Bo fine, liner uses the face felt, short cut felt to increase jointly, so that increase the amount that contain gum, enhance impervious ability. Intensity layer basically satisfies the intensity of lay aside canister and stiffness requirement. Select material should mature place chooses colophony matrix must with twine the fine that use Bo to have good wellability, so that form compact structural layer; Outside face and outside ambient are contacted directly, by be able to bear or endure ageing requirement select material.
2 glass reinforced plastics twine the design of lay aside canister
Glass reinforced plastics twines the design of lay aside canister to basically include: Time of drawing of patterns of design of mechanical structure design, lay up technology, solidify is reasonable and affirmatory wait. The mechanical structure design of lay aside canister should ensure the intensity of lay aside canister and stiffness satisfy use requirement, make the deflection of lay aside canister is inside formulary limits. Designing main basis is, what the stress that place of layer of structure of lay aside canister suffers is less than structural layer is allowable stress, namely δ ＜ [δ ] ; The Xiaoyu of meet an emergency of structural layer is allowable meet an emergency, namely] of ε <[ε . The winding pattern that determines layer of structure of lay aside canister with this both and twine number of plies. Mechanical structure design is very important. If the design is unreasonable, lay aside canister suffers force to be out of shape bring about lay aside canister local be proud crackle, structural layer is destroyed will bring about leakage of lay aside canister directly. Lay up craft designs canister of main basis lay aside mechanical structure design decides structure of specific lay up and production fulfil plan, the result technology that designs mechanical structure is changed.
