Abstract
The invention discloses a kind of grease proofing processing method of moulding of plant fibres type goods, pass through brooming, fused, the processing method of absorption and sizing carrys out the processing to string, be that polyfluoro replaces sour water shape dispersion to carry out safe anti-oil tech by oil-proofing agent again, be 200-230 degree by high temperature, the sizing of high pressure 3.5-4.5KG ensure that the grease proofing of string not easily produces seepage in use in-30 DEG C of-100 DEG C of environment, its polyfluoro of work in-process replaces the use amount of the oil-proofing agent of sour water shape dispersion less, process operation is convenient, and the use safety that ensure that consumer can be disengaged by innocuous substance.
Description
Technical field
The grease proofing processing method of a kind of moulding of plant fibres type goods for paper container of food or beverage of the present invention.
Background technology
Paper products are renewable with its raw material, printing is convenient, the feature such as easy recovery and easy degraded after discarded, be widely used in packaging for foodstuff always, especially disposable food packing and Dining tool field, therefore, the health of packaging paper product, security performance more should cause the attention of government and consumers in general.Disposable paper Dining tool gos deep into huge numbers of families as very important consumer goods, as goods such as instant noodle bowl, milky tea cup, disposable water glass, disposable paper bowls.There is the existence of paper container of food or beverage in the place that nearly all needs such as bank, shop, aircraft, train, steamer, office drink water, have a meal, even in most consumer family, pottery originally, glass all replace by dixie cup, especially dixie cup guests is used, become and expressed the distinguished a kind of mode of guest, in order to ensure the health of diet, home and abroad is to the requirement specification of paper container of food or beverage also day by day strict and made relevant laws and regulations and implementation criteria.
But with regard to the safety problem of present paper container of food or beverage, show through experimental investigation: present paper container of food or beverage utilizes the next grease proofing present paper container of food or beverage of " PE " film to utilize " PE " film to carry out waterproof traditionally traditionally, its using amount of reagent is larger, operation inconvenience, it uses easy seepage in-30 DEG C of-100 DEG C of environment, and harmful substance can disengage this just to the unsafe hidden danger of diet that consumer brings.
Summary of the invention
Object of the present invention is overcome the deficiency existed in background technology, now puies forward the grease proofing processing method of moulding of plant fibres type goods.
For achieving the above object, the present invention adopts following scheme:
A grease proofing processing method for moulding of plant fibres type goods, comprises the steps: a, brooming: string is soluble in water, is stirred and makes the abundant brooming of string, make string itself be full of granular burr by waterpower driven rotary; B, fused: oil-proofing agent is fully dissolved in the solution of string, make grease proofing ion invest on the burr of the string after brooming sufficiently uniformly; C, absorption: stir, by making string be adsorbed on equably on formation mould after water suction; D, sizing: make string carry out sizing and solidifying on mould finally by high temperature, high pressure.
In order to perfect scheme, described oil-proofing agent is polyfluoro.
In order to perfect scheme, in stepb, the ratio of described oil-proofing agent and string is 0.06-0.09.
In order to perfect scheme, in step c, described string makes string be adsorbed on equably on formation mould by vacuum dehydration.
In order to perfect scheme, in steps d, described high temperature is 200-230 degree, high pressure 3.5-4.5KG.
In order to perfect scheme, in steps d, in high temperature, high pressure, carry out the mould shape of 30-50 second
The present invention's beneficial effect is compared to existing technology: wherein polyfluoro replaces sour water shape dispersion oil-proofing agent to make it grease proofing effective, and work in-process polyfluoro replaces sour water shape dispersion use amount less, process operation is convenient, and not easily produce seepage in using in-30 DEG C of-100 DEG C of environment, and the use safety that ensure that consumer can be disengaged by innocuous substance.
Accompanying drawing explanation
Fig. 1 is the flow chart of the grease proofing processing method of moulding of plant fibres type goods of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described:
With reference to figure 1, a kind of grease proofing processing method of moulding of plant fibres type goods, comprises the steps: a, brooming 100: string is soluble in water, is stirred and makes the abundant brooming of string, make string itself be full of granular burr by waterpower driven rotary; B, fused 200: be fully dissolved in the solution of string by oil-proofing agent, makes grease proofing ion invest on the burr of the string after brooming sufficiently uniformly; C, absorption 300: stir, by making string be adsorbed on equably on formation mould after water suction; D, sizing 400: make string carry out sizing and solidifying on mould finally by high temperature, high pressure.
In order to ensure its grease proofing effect, described oil-proofing agent is polyfluoro.And in stepb, the ratio of oil-proofing agent and string is 0.06-0.09, make it while arriving grease proofing effect, reduce the consumption of reagent by its component ratio.
In order to can effective high-quality sizing, in step c, described string makes string be adsorbed on equably on formation mould by vacuum dehydration.Described high temperature is 200-230 degree, the mould shape of 30-50 second is carried out in high pressure 3.5-4.5KG, ensure that the stability of its anti-oil processing ensure that it not easily produces seepage in using in-30 DEG C of-100 DEG C of environment by this machined parameters, and the use safety that ensure that consumer can be disengaged by innocuous substance.
In process operation, utilize the mutual suction-operated of zwitterion, oil-proofing agent polyfluoro is fully invested plant fibre surface, is evenly distributed in plant fibre surface in process of production.Exactly production process first by string fully " brooming " make fiber itself be full of granular burr even if string presents to open as broom, again that oil-proofing agent is fully water-soluble, grease proofing ion is made to invest on the fiber burr of " brooming " sufficiently uniformly, stir again, be spread out in equably on formation mould by making string after vacuum dehydration, be 200-230 degree finally by high temperature, string after high pressure 3.5-4.5KG makes processing solidifies on shaper, and string evenly wraps up and reaches grease proofing object by grease proofing ion.
The foregoing is only preferred embodiment of the present invention, is not restriction with the present embodiment, and all any amendments done within the spirit and principles in the present invention, equivalent replacement or improvement etc., all should be included within protection scope of the present invention.
