Uyenza kanjani ifilimu ye-cellulose?

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 elifiswayo lokushintshwa.

Ifilimu esobala ekhiqizwe ku-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.
