Description
Technical field
Invention is related to petroleum chemical engineering oil storage tank equipment volatilization prevention technical field of structures, specially a kind of to be used for oil storage tank
Sandwich fiberglass in floating plate and production method.
Background technology
Interior floating plate is that one kind is lifted with storage tank liquid surface-floated, reduces medium volatilization, subtracts low-loss energy-saving environmental protection device, be
A kind of safeguard measure that is common both at home and abroad and effectively reducing oil product volatilization.The structure and material of currently used inner floating roof of stock tank
Matter, according to national standard and professional standard《Vertical cylinder steel welding storage oil tank design codes》GB50341-2014 and《Petrochemical industry is vertical
Formula cylinder steel welding tank designs specification》SH3046-92；Float-type and compartment-type structure type, material can be divided usually to have carbon
Three kinds of steel, aluminum and stainless steel.Structure and the material selection of inner floating roof of stock tank should follow the following aspects：(1), weight
Gently, good and facilitate installation by the uniform unsinkability of buoyancy；(2), intensity is high, is generated stress deformation by uneven buoyancy and resisted dynamic
State load-carrying ability is strong；(3), rigidity is big, small by sagging deflection deformation is acted on down from heavy load；(4), thermal conductivity is low, has certain
Heat insulating function is to reduce oil product volatile quantity；(5), resistance to chemical corrosion is good, and there is longer service life and later period maintenance to support
Shield is few；(6), processing and fabricating is simple and working security is high；(7), it transports and easy for installation, engineering comprehensive cost is relatively low.
But at present in the more steel of engineer application and stainless steel compartment-type and aluminum float-type floating plate no matter from adding
All there is larger deficiency in work, installation, service life and comprehensive cost etc.；Floating plate is due to from great in steel, processing peace
It fills difficulty greatly and service life is most short, stop using substantially at present；Result of Aluminium Internal Float Valve Tray provides buoyancy using floating drum, is easy by buoyancy
Uneven to cause unsinkability poor, own wt is greatly and rigid deficiency causes whole sagging deflections big, aluminium resistance to chemical corrosion
It is poor with anti-aging property, therefore its service life only has 8 years and later maintenance is more, comprehensive cost is high；Floating plate uses in stainless steel
Compartment-type structure, from great, insufficient rigidity deformation is big, the difficult safety of processing installation is poor, 12 years service lifes but later maintenance
More, comprehensive cost is high；Petrochemical equipment engineers and technicians are the oil storage tank for changing common traditional material and labyrinth
The drawbacks described above of interior floating plate and a large amount of theoretical and experimental test of insufficient progress, but since the material property of traditional material itself causes
Make that conventional steel, the use of floating plate is constantly subjected to restrict and query in aluminum and stainless steel.
To change the structure and manufacturing technology level of the state of the art of floating plate and promotion inner floating roof of stock tank in traditional material,
The invention release it is a kind of using polypropylene cellular board and glass-reinforced plastic material design and manufacture, it is unification simple in structure, light-weight, strong
Floating plate in the honeycomb sandwich construction fiberglass that degree is high, rigidity is big, thermal conductivity is low and resistance to chemical corrosion is good, it is intended to push oil storage
The update and processing mounting technique level progress of floating plate structure and material in tank.

70mm, when because region limitation overlap joint do not need then in time cut suitable width felt repaired；
S5, polypropylene cellular board bonding
1. kickboard layer and lower covering complete and after it is fully cured, rough place are polished flat, if
The place for having polishing excessive is then impregnated with epoxy-modified vinylite filling-in with alkali-free glass fiber chopped strand mat；
2. cleaning out polypropylene cellular board bonding construction area, whole one layer of epoxy-modified vinylite dosage of brushing is 1
Polypropylene cellular board, is then pressed onto in the laying of bottom by ㎏/㎡；
3. polypropylene cellular board bottom surface must not have flow empty phenomena, complete for the bottom surface and lower covering laying that ensure polypropylene cellular board
Full connected need to use weight to be compressed in polypropylene cellular board upper surface until bottom resin layers are solid for 10~15kg/ sand buckets
Change；
4. after the completion of the bonding solidification of polypropylene cellular board bottom surface, polypropylene honeycomb plate top surface is cleaned out, it is excessive between cellular board
Gap cellulor plate slice fill up, pay attention to thering is the face-up of non-woven fabrics when filling up, to ensure cellular board and upper covering
Laying has good interface；
5. smearing one layer of epoxy-modified vinylite in the top surface of polypropylene cellular board, dosage is 1 ㎏/㎡, and resin must fill
The non-woven fabrics of the saturating honeycomb plate top surface of sub-dip；
6. checking the seam crossing of polypropylene cellular board, the need of fissure of displacement larger part cut fritter polypropylene cellular board plug and block up and pour into ring
Oxygen modified vinyl resin is filled up, if seam crossing both sides drop is larger, the chamfering that need to polish blend compounds mud transition, to avoid laying
The air in seaming position gap is occurred a large amount of bubbles by heating in epoxy-modified vinylite solidification process afterwards, owns
Seam is all made of the alkali-free glass fiber chopped strand mat that a slice width degree is 50mm and infiltrates epoxy modified vinyl resin progress pre edge seal
Processing；
S6, upper covering (24) make
1. cleaning out polypropylene honeycomb plate top surface, then it is uniformly coated with one layer of epoxy-modified vinylite；
2. being laid with alkali-free glass fibre surface felt and alkali-free glass fiber chopped strand mat in the following order：
A, 2 layers of alkali-free glass fiber chopped strand mat are laid with；
B, it is laid with 1 layer of alkali-free glass fibre surface felt；
Wherein, one layer of epoxy-modified second must be brushed by being often laid with one layer of alkali-free glass fibre face felt and alkali-free glass fiber chopped strand mat
Ene based resins to ensure that fibrous material is thoroughly impregnated resin, while using pressure roller row's bubble；
S7, upper epidermis (25) make
1. upper covering checks its surface after making laying solidification, need to polish burr and bubble if there are burr or bubble
Fall, infiltrates epoxy modified vinyl resin reparation using alkali-free glass fiber chopped strand mat after cleaning up；
2. allocating upper epidermis makes the mixture brushed, the mixing quality ratio of graphite powder, fire retardant and epoxy-modified vinyl tree
It is 20：12：100, mixing time is no less than 15 minutes；
3. one layer of mixture is uniformly brushed whole, mixture must not be poured in printed regions by when brushing uses hair roller coating brush again,
It must be with row is equably brushed on upper covering laying surface again after hair roller dipping mixture；
S8, kickboard (2) and side guard (26)) from the bottom to top superposition lamination making is molded on construction formwork successively, while applying
It is infiltrated using alkali-free glass fiber surface felt and alkali-free glass fiber chopped mat with guide post (3), exhaust pipe (5) and manhole (6) in work template
Hybrid epoxidized one volume layer of modified vinyl resin of graphite powder makes.
9. the production method of floating plate, feature in a kind of sandwich fiberglass for oil storage tank as claimed in claim 9
It is：The specification of the I-beam is width 80 × 200 × length of height 6000mm, the specification of the template for length 2440 ×
Fire prevention overlay coating is done in width 1220 × thickness 15mm, upper surface, ensures template surface smoothness, template thickness deviation no more than
±0.5mm。
