Ubunzulu obahlukeneyo bokuSebenza kwePhepha leBamboo

Ngokweendlela ezahlukeneyo zokucubungula, i-pulp yephepha le-bamboo inokwahlulwahlulwa ibe ziindidi ezahlukeneyo, ikakhulu kuquka i-Unbleached Pulp, i-Semi-bleached Pulp, i-Bleached Pulp kunye ne-Refined Pulp, njl. I-Unbleached Pulp ikwaziwa njenge-unbleached pulp.

1. Intlama Engatyhefwanga

Iphepha le-bamboo elingaxutywanga, elaziwa ngokuba yi-pulp engaxutywanga, libhekisa kwi-pulp efunyenwe ngqo kwi-bamboo okanye kwezinye izinto eziluhlaza zefayibha yezityalo emva konyango lokuqala ngeendlela zeekhemikhali okanye zemishini, ngaphandle kokuyixuba. Olu hlobo lwe-pulp lugcina umbala wendalo wezinto eziluhlaza, ngokuqhelekileyo ukusuka kumthubi okhanyayo ukuya kumdaka omnyama, kwaye luqulathe umlinganiselo ophezulu we-lignin kunye nezinye izinto ezingezizo iiselilulo. Iindleko zemveliso ye-pulp yemibala yendalo ziphantsi kakhulu, kwaye isetyenziswa kakhulu kwiindawo ezingadingi mhlophe ophezulu wephepha, njengephepha lokupakisha, ikhadibhodi, inxalenye yephepha lenkcubeko njalo njalo. Inzuzo yayo kukugcina iimpawu zendalo zezinto eziluhlaza, ezilungele ukusetyenziswa ngokuzinzileyo kwezixhobo.

2. I-Pulp exutywe kancinci

Iphepha le-bamboo elinombala oluhlaza okwesibhakabhaka (i-Pulp) luhlobo lwe-pulp ephakathi kwe-pulp yendalo kunye ne-pulp enombala oluhlaza okwesibhakabhaka. Idlula kwinkqubo yoku-bleach engaphelelanga, kodwa inqanaba loku-bleach alikho nzulu njengele-pulp enombala oluhlaza okwesibhakabhaka, ngoko ke umbala uphakathi kombala wendalo kunye nomhlophe ococekileyo, kwaye usenokuba nombala othile otyheli. Ngokulawula ubungakanani be-bleach kunye nexesha loku-bleach ngexesha lokuveliswa kwe-pulp enombala oluhlaza okwesibhakabhaka, kunokwenzeka ukuqinisekisa inqanaba elithile lobumhlophe ngelixa kwangaxeshanye kunciphisa iindleko zemveliso kunye nempembelelo yokusingqongileyo. Olu hlobo lwe-pulp lufanelekile kwiimeko apho kukho iimfuno ezithile zobumhlophe bephepha kodwa kungabi bumhlophe kakhulu, njengeentlobo ezithile zephepha lokubhala, iphepha lokuprinta, njl.

3. I-Bleached Pulp

I-bleached paper bamboo pulp yi-bleached pulp epheleleyo, umbala wayo usondele kumhlophe omsulwa, i-high whiteness index. Inkqubo ye-bleach idla ngokusebenzisa iindlela zeekhemikhali, ezinje ngokusebenzisa i-chlorine, i-hypochlorite, i-chlorine dioxide okanye i-hydrogen peroxide kunye nezinye izinto ze-bleach, ukuze kususwe i-lignin kunye nezinye izinto ezinemibala kwi-pulp. I-bleached pulp inobunyulu befayibha ephezulu, iipropati ezilungileyo zomzimba kunye nozinzo lweekhemikhali, kwaye yeyona nto iphambili yokwenza iphepha lenkcubeko elikumgangatho ophezulu, iphepha elikhethekileyo kunye nephepha lasekhaya. Ngenxa yobumhlophe bayo obuphezulu kunye nokusebenza kakuhle kokucubungula, i-bleached pulp ithatha indawo ebalulekileyo kushishino lwephepha.

4. I-Pulp yephepha elicociweyo

I-Refined Pulp idla ngokubhekisa kwi-pulp efunyenwe ngesiseko se-bleached pulp, enyangwa ngakumbi ngeendlela zomzimba okanye zeekhemikhali ukuphucula ubunyulu kunye neempawu zefayibha ye-pulp. Le nkqubo, enokubandakanya amanyathelo anje ngokusila kakuhle, ukuhluza kunye nokuhlamba, yenzelwe ukususa iifayibha ezincinci, ukungcola kunye neekhemikhali ezingaphendulwanga ngokupheleleyo kwi-pulp nokwenza iifayibha zisasazeke kwaye zithambile, ngaloo ndlela ziphucula ukuguda, ukukhanya kunye namandla ephepha. I-pulp ecociweyo ifanelekile ngokukodwa kwimveliso yeemveliso zephepha ezinexabiso eliphezulu, ezifana nephepha lokuprinta elikumgangatho ophezulu, iphepha lobugcisa, iphepha eligqunyiweyo, njl.njl., ezineemfuno eziphezulu zokuqina kwephepha, ukufana kunye nokuguquguquka kokuprinta.
