Yini i-pulp?

I-Pulp iyi-fibrous material etholakala emicu yezitshalo ngezindlela ezahlukene zokucubungula.Ingahlukaniswa ibe yi-pulp engumshini, i-pulp yamakhemikhali kanye ne-chemical mechanical pulp ngokusho kwendlela yokucubungula;ingabuye ihlukaniswe ibe yi-pulp yokhuni, i-straw pulp, i-hemp pulp, i-pulp yomhlanga, i-pulp yomoba, i-bamboo pulp, i-rag pulp nokunye ngokusho kwe-fiber eluhlaza esetshenzisiwe.Ingabuye ihlukaniswe ibe yi-pulp ecwengiwe, i-bleached pulp, i-pulp engaxutshwe, i-high-ield pulp, kanye ne-semi-chemical pulp ngokusho kokuhlanza okuhlukene.Ngokuvamile esetshenziswa ekwenzeni iphepha kanye amakhadibhodi.I-pulp ecwengisisiwe ayisetshenziselwa kuphela ukwenza iphepha elikhethekile, kodwa futhi ivame ukusetshenziswa njengempahla eluhlaza ekwenzeni okuphuma ku-cellulose njengama-cellulose esters nama-cellulose ethers.Ibuye isetshenziswe kumafayibha enziwe umuntu, amapulasitiki, ama-coatings, amafilimu, isibhamu kanye neminye imikhakha.

I-pulping evamile ibhekisela ohlelweni lokukhiqiza lokuhlukanisa izinto zokusetshenziswa kwefayibha yezitshalo zibe yi-pulp yemvelo noma e-bleached ngezindlela zamakhemikhali, izindlela zemishini noma inhlanganisela yalezi zindlela ezimbili.Inqubo evame ukusetshenziswa ukuhlikihla, ukupheka, ukuwasha, ukuhluza, ukucwecwa, ukuhlanza nokomisa izinto ezingavuthiwe zefayibha yezitshalo.Indlela entsha ye-biological pulping iye yasungulwa ezikhathini zanamuhla.Okokuqala, amabhaktheriya akhethekile (ukubola okumhlophe, ukubola okunsundu, ukubola okuthambile) kusetshenziselwa ukubola ngokuqondile isakhiwo se-lignin, bese kusetshenziswa izindlela zemishini noma zamakhemikhali ukuhlukanisa i-cellulose esele., kulandele ukuhlanza.Kule nqubo, izinto eziphilayo zibolile futhi zavula iningi le-lignin, futhi indlela yamakhemikhali isetshenziswa kuphela njengomsebenzi osizayo.Uma kuqhathaniswa nendlela yendabuko, imikhiqizo yamakhemikhali esetshenziswayo mincane, ngakho-ke uketshezi olulahliwe oluncane noma alukho lungakhishwa.Kuyindlela ye-pulping ehambisana nemvelo., Indlela ye-pulping ehlanzekile.
