Abstract
The production method of coconut fibre as raw material for making paper pulp includes the following steps: stripping coconut to take out coir fibre ball, over-drying, crushing and pulverizing, then placing the pulverized coir fibre in the extracting tank, adding polar solvent and soaking coir fibre, circulation cleaning at normal temp. and normal pressure for 3-5 min., dewaxing, then removing solvent, taking out coir fibre, and drying the dewaxed coir fibre to obtain the invented raw material for making paper pulp. Said invention can fully utilize waste coir fibre to make paper pulp, does not pollute environment, but also can produce food-level paper pulp.
Description
The present invention relates to paper pulp raw material, particularly a kind of manufacture method of utilizing coir fibre to make paper pulp raw material.
Existing paper making raw material generally adopts timber, bark, bamboo, bagasse, reed, straw, straw etc., and wherein raw material such as timber, bark is strengthened the protection environment, kept ecological balance because of need, and its utilization of resources has been restricted; Raw material that also has such as straw, straw, bagasse, owing to may be subjected to the pollution of agricultural chemicals, chemical fertilizer, so should not be made into the food-grade paper pulp raw material.
Yet people just reach its maturity to the comprehensive utilization of coconut, and Coconut Juice, coconut meat are wholefoods, can be made into coconut milk, shredded coconut meat, food flavor etc., and coconut fruit stone duricrust can utilize the production active carbon.Having coconut palm shell outer fiber only still underuses, have only minimum part coir fibre to be useed as monofilament and be used to make sofa, most coir fibres are discarded by people, also need change expense great amount of manpower and material resources and financial resources and be handled, generally carry out burning disposal, can cause environmental pollution thus.
The purpose of this invention is to provide a kind of manufacture method of utilizing coir fibre to make paper pulp raw material, make full use of discarded coir fibre and make paper pulp, neither produce environmental pollution, can be used as food-grade paper pulp again.
Technical scheme of the present invention is as follows:
A kind of manufacture method of utilizing coir fibre to make paper pulp raw material, it comprises following three processed processes:
(1) decorticating processing: peel off down the coir fibre ball from coconut husk, put into the drying tunnel oven dry, heating-up temperature is 100 ℃～110 ℃, and be 15～25 minutes heat time heating time, takes out the coir fibre ball then, through the breaker grating, pulverizes through pulverizer again;
(2) extraction dewaxing: coir fibre is positioned in the extraction tank, adds polar solvent, make solvent submergence coir fibre, wash cycles is 3～5 minutes at normal temperatures and pressures, makes coir fibre remove sodium laurate oil, and promptly solvent is got rid of in dewaxing subsequently, takes out coir fibre;
(3) oven dry is handled: the coir fibre after will dewaxing is put into the drying tunnel oven dry, and heating-up temperature is 100 ℃～110 ℃, and be 15～25 minutes heat time heating time, takes out the coir fibre after drying then, as paper pulp raw material.
The present invention makes full use of discarded coir fibre and makes paper pulp, and the comprehensive utilization complete to coconut contributes, to save national resources, turn waste into wealth, environmental protection and regional poverty alleviation etc. have positive meaning.Implement the made paper pulp of the present invention and can be used as the food-grade paper pulp raw material, be widely used in packaging material and papery articles for use such as disposable paper tableware.
By the paper pulp that method of the present invention is made, its fibre strength is good, and flexible can be mixed with other classification paper pulp, to produce multi-purpose paper product.Because the coir fibre that utilized is cheap, its pulping cost is far below traditional pulping cost, thereby has very strong competitiveness.
Below in conjunction with embodiment the present invention is elaborated.
A kind of manufacture method of utilizing coir fibre to make paper pulp raw material, need carry out following three processed processes:
First step: decorticating processing.
Peel off down the coir fibre ball from coconut husk, because of fibre ball contains moisture, so need put into the drying tunnel oven dry, heating-up temperature is 100 ℃～110 ℃, and the best is 105 ℃, ± 2 ℃; Be 15～25 minutes heat time heating time, and the best is 20 minutes, ± 2 minutes.Take out the coir fibre ball then,, send into pulverizer again and pulverize through the breaker grating.
Second step: extraction dewaxing.
Coir fibre after pulverizing is positioned in the extraction tank, adds polar solvent, make solvent submergence coir fibre, wash cycles is 3～5 minutes at normal temperatures and pressures, makes coir fibre remove sodium laurate oil, just dewaxing.Get rid of solvent subsequently, take out coir fibre.
Polar solvent in the above-mentioned adding extraction tank is a kind of benzinum, or a kind of tetrachloro-ethylene, or a kind of trichloro-ethylene, also can be trichloroethanes.
Third step: oven dry is handled.
Coir fibre after the dewaxing is put into drying tunnel dry, heating-up temperature is 100 ℃～110 ℃, and the best is 105 ℃, ± 2 ℃; Be 15～25 minutes heat time heating time, and the best is 20 minutes, ± 2 minutes.Take out the coir fibre after drying then, promptly can be used as paper pulp raw material, send to papermaking.
