Uyenza njani ifilimu yeselula?

Ifilimu yeselfowuniUkupakisha sisisombululo sokupakishwa kwe-bio-rattage eyenziwe ukusuka kwiinkuni okanye umqhaphu, zombini ezinokuthi zilungelelaniswe ngokulula. Ngaphandle kokupakishwa kwefilimu kudlulisa ubomi beshesi yemveliso entsha yokuvelisa umxholo wokufuma.

Isetyenziswa njani i-sellulose yokupakisha?

I-Cellophane ingumntu onqabileyo, obonakalayo, kunye nefilimu enokwenziwa ngokupheleleyo okanye ishiti eyenziwe kwi-selsulose ehlaziyiweyo. UCellophane uluncedo ekupakikweni ukutya ngenxa yokuqhutywa komhlaba okuphantsi, ioyile, iigrisi, kunye namanzi. Ibize, ke ngoko, isetyenziswe njengento yokutya yokutya phantse inkulungwane.

Yenziwe njani ifilimu ye-sellwase?

I-Selsulose i-Selsutate idla ngokwenziwa kwi-pulp ye-pulp ngokusabela kwi-acetic acid kunye ne-acetic adhydride phambi kwe-sulfuric acid ukuba ibe yi-sulcelose ye-sulfuric. I-triacetate ke ye-hydrolyzed ye-hydrolyzed ukuya kwinqanaba elifunekayo lokufaka endaweni.

Ifilimu ebonakalayo eyenziwe kwi-pulp.Iifilimu zeLwimizenziwa kwi-sellulose. (I-sellyulose: Into ephambili yeendonga zeseli zezityalo) Ixabiso le-calolorifi eliveliswe ngokudibana liphantsi kwaye akukho longcoliseko lwenqanaba lenzeka ngegesi.

Uyenza njani iplastiki yeselcelose?

I-selsulose plastics zenziwa zisebenzisa imithi yefowuni njengezinto ezisisiseko. Iinkolelo zomthi zahlulwe kwaye zinokusetyenziswa njengomthombo wamandla kwimveliso. Ukuya kwi-fiber ye-sellsate fiber evela emthini, umthi uphekwe okanye ushushu kwi-digerster.
