Production technology is removed from office without chrome tanning automobile cushion the invention discloses one kind, is comprised the following steps：Feeding, immersion, fleshing, liming, split, deliming, softening, pickling, tanning, semi-finished product scytoblastema, finished product.This production technology can carry out the processing of finished leather to Animal Skins such as ox-hides, not only can be with pollution of the customer service heavy metal chromium to environment, reduce the cost of enterprise's sewage disposal, the leather products produced are soft simultaneously, plentiful, high resilience, elegant, grain are put down thin, bright-colored, and physical and mechanical properties is fully able to the requirement that reaches conventional chrome leather.
Description
Technical field
The present invention relates to a kind of automobile cushion to remove from office production technology, particularly a kind of to remove from office production technology without chrome tanning automobile cushion.
Background technology
Traditional tanning technology is to use chrome tanning, and fur is made blue skin, the process for allowing fur to change to leather, and this process is to use
Chrome tanning agent and leather fiber, which react, generates stable chemical constitution, reaches the purpose of post-production.With the development of the society,
Country greatly develops enterprise while does not forget the social environment of blue mountains and green waters, and this also forces us leather industry also constantly to strengthen
Technical improvement and innovation, traditional tanning technology can not be applicable the development of society, traditional tanning technology and process hides
It is not ep-type material that chemical materials used, which has many, such as contains the harmful substances such as benzene, formaldehyde, pentachlorophenol, heavy metal,
It can be absorbed by the body when being contacted with human body zero distance, human body is caused damage, can also given up with poisonous material to enterprise during process hides
Water process causes very big difficulty, is difficult sometimes that processing is clean, emitting can pollute to environment and water source, to society
Cause great harm.
The content of the invention
Production technology is removed from office without chrome tanning automobile cushion the technical problem to be solved in the present invention is to provide one kind, was both reduced at sewage
Managing difficulty reduces processing cost, reduces the pollution to environment again.
In order to solve the above-mentioned technical problem, one kind of the invention removes from office production technology, including following step without chrome tanning automobile cushion
Suddenly,
(A) feeding：Ox-hide is extracted as raw material skin；
(B) soak：Contained using rotary drum and in rotary drum into immersion liquid, the weight ratio of soak liquid and raw material skin is 2:1, protect
Warm 23-25 DEG C, hour time 20-28；
(C) fleshing：The counterdie of raw material skin is removed clean；
(D) liming：The mixed solution into liming agent, lime and vulcanized sodium is contained using rotary drum and in rotary drum, by raw material skin
It is immersed in mixed solution, hour time 20-28, makes collagenous fibres separation, loose, contraction in length, the thickness of raw material skin, elasticity
And transparency increase, swelling state is presented；
(E) split：One layer of skin is cutd open into several layers of skin using splitter, and makes the thickness of skin between 0.3-0.4mm；
(F) deliming：Using ox-hide of the method for the washing plus deliming agent processing in swelling state, minute time 25-35, go
Except intracutaneous grey alkali, and expansion is set tentatively to eliminate；
(G) soften：Softened using macerating enzyme, minute time 15-25；
(H) pickling：By the sulfuric acid of mass concentration 94% and the formic acid of mass concentration 84% and the water mixed diluting of 20 times of quality
For acid solution, ox-hide is immersed in the acid solution, minute time 170-190；
(I) tanning：Ox-hide is put into organic aldehyde and the mixed solution for synthesizing vegetable tanning agent and carries out tanning, it is white so as to obtain
Wet skin；
(J) semi-finished product scytoblastema：Wet-white leather dyes semi-finished product scytoblastema through over-pressed water, split and shaving process using pigment；
(K) finished product：Semi-finished product scytoblastema turns into finished product by arranging, spraying and cover with paint, lacquer, colour wash, etc. process
Arranging process comprises the following steps in the step K,
(K1) do soft：Dried leather is hardened using oscillator and rotary drum, area contraction etc. carries out sofening treatment；
(K2) buffing：Grain side of leather disability is moderately eliminated using buffing machine, improves leather grade；
(K3) it is embossed：Assign leather different surface details using through-feed embossing machine, meet the esthetic requirement of people；
(K4) cover with paint, lacquer, colour wash, etc.：One layer of coloured or colourless natural or conjunction is covered with paint, lacquer, colour wash, etc. on the leather dried and arranged using flush coater
Into high molecular film material.
The beneficial effects of the invention are as follows：This no chrome tanning automobile cushion leather production technology can be carried out to Animal Skins such as ox-hides
The processing of finished leather, the cost of enterprise's sewage disposal with pollution of the customer service heavy metal chromium to environment, can be not only reduced, is produced simultaneously
Come leather products are soft, plentiful, high resilience, elegant, grain are put down thin, bright-colored, and physical and mechanical properties is complete
The requirement of conventional chrome leather all can enough be reached.
Embodiment
The a kind of of the present invention removes from office production technology without chrome tanning automobile cushion, comprises the following steps,
(A) feeding：Ox-hide is extracted as raw material skin；
(B) soak：Contained using rotary drum and in rotary drum into immersion liquid, the weight ratio of soak liquid and raw material skin is 2:1, protect
24 DEG C of temperature, 24 hours time；
(C) fleshing：The counterdie of raw material skin is removed clean；
(D) liming：The mixed solution into liming agent, lime and vulcanized sodium is contained using rotary drum and in rotary drum, by raw material skin
Be immersed in mixed solution, 24 hours time, make collagenous fibres separation, loose, contraction in length, the thickness of raw material skin, elasticity and
Transparency increase, is presented swelling state；
(E) split：One layer of skin is cutd open into several layers of skin using splitter, and makes the thickness of skin between 0.3mm；
(F) deliming：Using ox-hide of the method for the washing plus deliming agent processing in swelling state, 30 minutes time, remove
Intracutaneous grey alkali, and expansion is tentatively eliminated；
