Ifilimu ye-celluloseukupakisha kuyisixazululo se-bio-compostable sephakheji esakhiwe ngokhuni noma ukotini, kokubili okuvundiswa kalula.Ngaphandle kokupakishwa kwefilimu ye-cellulose kwandisa impilo yeshalofu yemikhiqizo emisha ngokulawula okuqukethwe komswakama.
Isetshenziswa kanjani i-cellulose emaphaketheni?
I-Cellophane iyifilimu noma ishidi elincanyana, elisobala, nelibolayo ngokuphelele elakhiwe nge-cellulose evuselelwe.I-Cellophane iwusizo ekufakweni kokudla ngenxa yokungafinyeleli kwayo kancane emoyeni, emafutheni, emafutheni, emabhaktheriya nasemanzini.Ngakho-ke, isetshenziswe njengempahla yokupakisha ukudla cishe iminyaka eyikhulu.
Yenziwa kanjani ifilimu ye-cellulose acetate?
I-Cellulose acetate ngokuvamile yenziwa kusuka ku-pulp yokhuni ngokuphendula nge-acetic acid ne-acetic anhydride phambi kwe-sulfuric acid ukwenza i-cellulose triacetate.I-triacetate ibe seyenziwe i-hydrolyzed kancane ibe yizinga elifunekayo lokushintshwa.
Ifilimu esobala eyenziwe nge-pulp.Amafilimu e-cellulosezenziwe nge-cellulose.(I-Cellulose: Into eyinhloko yezindonga zamaseli ezitshalo) Inani le-calorific elikhiqizwa ngokusha liphansi futhi akukho ukungcoliswa kwesibili okwenzeka ngegesi yokuvutha.
Uyenza kanjani ipulasitiki ye-cellulose?
Amapulasitiki e-cellulose akhiqizwa kusetshenziswa izihlahla ze-softwood njengezinto eziyisisekelo zokusetshenziswa.Amagxolo esihlahla ayahlukaniswa futhi angasetshenziswa njengomthombo wamandla ekukhiqizeni.Ukuhlukanisa i-cellulose fiber esihlahleni, isihlahla siyaphekwa noma sishiswe ku-digester.
Uma usebhizinisini lamafilimu angaboli, ungase ulithande
