Iindidi zePulp zePhepha ngokwemathiriyeli ekrwada

Kwishishini lephepha, ukhetho lwemathiriyeli ekrwada lubaluleke kakhulu kumgangatho wemveliso, iindleko zemveliso kunye nefuthe lokusingqongileyo. Umzi-mveliso wephepha uneentlobo ngeentlobo zemathiriyeli ekrwada, ingakumbi ebandakanya intlama yeplanga, i-pulp ye-bamboo, i-pulp yengca, i-pulp ye-hemp, i-cotton pulp kunye ne-pulp ye-waste paper.

1. Intlaka yeenkuni

I-Wood pulp yenye yezona zinto zixhaphakileyo ekrwada yokwenza iphepha, kwaye yenziwe ngomthi (intlobo ngeentlobo zeentlobo ezibandakanya i-eucalyptus) ngeendlela zekhemikhali okanye zoomatshini. Intlama yomthi ngokweendlela zayo ezahlukeneyo zokucofa, inokwahlulwa kwakhona ibe yintlama yekhemikhali (efana nepulp yesulphate, ipulp yesulphite) kunye nepulp yomatshini (efana nokusila ilitye lokusila intlama yeplanga, ukugawula okushushu komatshini). Iphepha le-wood pulp lineenzuzo zamandla aphezulu, ukuqina okulungileyo, ukufunxa inki eyomeleleyo, njl.

2. I-pulp ye-bamboo

I-bamboo pulp yenziwe nge-bamboo njengemathiriyeli ekrwada yepulp yephepha. I-bamboo inomjikelo omfutshane wokukhula, amandla okuvuselela amandla, yimathiriyeli ekrwada ehambelana nokusingqongileyo yokwenza iphepha. Iphepha le-bamboo pulp linobumhlophe obuphezulu, ukunyanzeliswa komoya okulungileyo, ukuqina okulungileyo kunye nezinye iimpawu, ezifanelekileyo ukuveliswa kwephepha lenkcubeko, iphepha eliphilayo kunye nenxalenye yephepha lokupakisha. Ngokwandiswa kolwazi lokusingqongileyo, imfuno yentengiso yephepha le-bamboo pulp iyakhula.

3. I-Grass pulp I-Grass pulp yenziwe ngeentlobo ngeentlobo zezityalo ezinezityalo (ezifana neengcongolo, i-wheatgrass, i-bagasse, njl.njl.) njengemathiriyeli ekrwada. Ezi zityalo zizityebi kwizibonelelo kunye neendleko eziphantsi, kodwa inkqubo ye-pulping inzima kakhulu kwaye idinga ukunqoba imingeni yeentsinga ezimfutshane kunye nokungcola okuphezulu. Iphepha le-Grass pulp lisetyenziselwa ukuveliswa kwephepha lokupakisha eliphantsi, iphepha langasese njalo njalo.

4. I-pulp ye-hemp

I-pulp ye-Hemp yenziwe ngeflakisi, ijute kunye nezinye izityalo ze-hemp njengemathiriyeli ekrwada yepulp. Iintsinga zesityalo se-Hemp ezinde, zomelele, zenziwe ngephepha le-hemp elinokumelana kakuhle nokukrazuka kunye nokuqina, ngakumbi ilungele ukuveliswa kwephepha lokupakisha lodidi oluphezulu, iphepha lemali yebhanki kunye nelinye iphepha elikhethekileyo lemizi-mveliso.

5. Intlama yomqhaphu

I-pulp yomqhaphu yenziwe ngomqhaphu njengemathiriyeli ekrwada ye-pulp. Imicu yecotton inde, ithambile kwaye ifunxa i-inki, inika i-cotton pulp paper ukuthungwa okuphezulu kunye nokusebenza kokubhala, ngoko isoloko isetyenziselwa ukwenza i-calligraphy ephezulu kunye nephepha lokupeyinta, iphepha lobugcisa kunye nephepha elithile elikhethekileyo.

6. Inkunkuma yePulp

I-pulp yenkunkuma, njengoko igama libonisa, yenziwe kwiphepha lenkunkuma elisetyenzisiweyo, emva kwe-deinking, ukuhlanjululwa kunye nezinye iinkqubo zonyango. Ukurisayikilishwa kwenkunkuma yenkunkuma ayigcini nje kuphela ubutyebi bendalo, kodwa ikwanciphisa ukukhutshwa kwenkunkuma, okuyindlela ebalulekileyo yokuphumeza uphuhliso oluzinzileyo lweshishini lephepha. I-pulp yenkunkuma ingasetyenziselwa ukuvelisa iintlobo ezininzi zamaphepha, kubandakanywa ibhokisi yebhokisi, ibhodi engwevu, ibhodi emhlophe ephantsi engwevu, ibhodi emhlophe esezantsi emhlophe, iphepha leendaba, iphepha lenkcubeko elihambelana nokusingqongileyo, iphepha lemizi-mveliso elisetyenzisiweyo, kunye nephepha lasekhaya.
