Chilichonse chomwe muyenera kudziwa za ma celluluse
Ngati mwakhala mukuyang'ana zinthu zopatsa chidwi, mwayi womwe mudamvapo za cellulose, omwe amadziwikanso kuti cellophane.
Cellophane ndi chomveka, cholocha chomwe chakhala chikuyenda kuyambira 1900s. Koma, zingakudabwitseni kudziwa kuti cellophane, kapena ma cellulose omwe ali pa cellulose, ndi zopangidwa ndi mbewu, kokhazikika, komanso zobiriwira "zobiriwira.
Kodi ma cellulose ndi chiyani?
Kuzindikira mu 1833, cellulose ndi chinthu chomwe chili mkati mwa chipinda cham'manja chazomera. Imapangidwa ndi mamolekyu a udzu wautali wa shuga, ndikupangitsa kuti ikhale polysaride (tanthauzo la sayansi) lazakudya).
Pamene ma cellulose angapo amalumikizana pamodzi, amapanga china chake chotchedwa ma microfibubrils, omwe ali osokonezeka komanso ovuta. Kukhazikika kwa microfibrils kumapangitsa kuti cellulose akhale molekyu abwino kugwiritsa ntchito ku Bioplastic.
Komanso cellulose ndiye bipolymer yabwino kwambiri padziko lonse lapansi, ndipo tinthu tawo zimakhala ndi zovuta zachilengedwe. Ngakhale pali mitundu ingapo ya cellose. Ma cellulose chakudya nthawi zambiri amakhala ma cellophane, woongoka, woonda, wa pulasitiki ngati wa pulasitiki.
Kodi ma cellulose amapangidwa bwanji?
Cellophane amapangidwa kuchokera ku cellulose yomwe yatengedwa kuchokera ku thonje, nkhuni, hemp, kapena zinthu zina zokolola zachilengedwe. Zimayamba ngati zamkati zoyera, zomwe ndi 92% -98% cellulose. Kenako, cellulose yaiwisi imadutsa njira zinayi zotsatirazi zomwe zimasinthidwa kukhala cellophane.
1. Ma cellulose amasungunuka mu alkali (mchere, mchere wa ionic wa mankhwala a alkaline) kenako okalamba kwa masiku angapo. Njira yosungunulira iyi imatchedwa kutengedwa.
2. Carbobon Dialfide amagwiritsidwa ntchito pakhungu loseketsedwa kuti apange yankho lotchedwa cellulose xanthate, kapena viscose.
3. Njira iyi imawonjezeredwa ku kusakaniza kwa sodium sulfate ndi kuchepetsa sulfuric acid. Izi zimatembenuza yankho kuti mubwezeretsere.
4. Kenako filimu yosewerera imadutsa zowiritsa zitatu. Choyamba kuchotsa sulufule, ndiye kuti muletse filimuyo, ndikuwonjezera glycerin kuti ikhale yolimba.
Zotsatira zake ndi cellophane, yomwe imagwiritsidwa ntchito mu phukusi la chakudya, makamaka kuti apange zikwama biovegrad celts kapena "zikwama Cello".
Kodi zinthu zili ndi phindu la zinthu ziti?
Ngakhale kuti njira yopangira ma cellulose ndizovuta, mapindu ake ndiodziwika.
Anthu aku America amagwiritsa ntchito matumba pafupifupi 100 biliyoni, amafuna kuti mitsuko yamafuta 12 biliyoni iliyonse chaka chilichonse. Kupitilira pamenepo, nyama zam'madzi 100,000 zimaphedwa m'matumba apulasitiki chaka chilichonse. Zimatenga zaka zoposa 20 za matumba apulasitiki okhudzana ndi ma petroleum kuti agwetse munyanja. Akatero, amapanga pulasitiki-ma pulasitiki omwe amalowa mu chakudya.
Dziko lathu likamakudziwa bwino anthu, timapitiliza kufufuza njira zina zochezeka, kusinthasintha kwa ma pulasitiki a petrolelem.
Kuphatikiza pa kukhala njira yopumira, cellulose imapereka phindu lalikulu zachilengedwe:
Kusungunuka & bio-kutengera
Chifukwa cellophane adapangidwa kuchokera ku cellulose kuchokera kuzomera, zimapangidwa ndi zinthu zokhazikika kuchokera ku zinthu za Bio, zosinthidwa.
Biodeggrad
Cellulose films ndi biodegradle. Mayeso awonetsa kuti ma cellulose omwe amapezeka pakompyuta m'masiku 28-60 ngati mankhwalawo sakudziwika ndi masiku 80-120 ngati atavala. Zimadetsanso m'madzi m'masiku 10 ngati chilibe kanthu ndipo pafupifupi mwezi ngati chikakutidwa.
Kongoka
Cellophane ndiotetezeka kuyika manyowa anu kunyumba, ndipo sizifunikira malo ogulitsa manyowa.
Malipiro a Chakudya Chakudya:
Mtengo wotsika
Celluluse kunyamula kuyambira 1912, ndipo ndi cholembera mafakitale. Poyerekeza ndi njira zina zochezera za eco-floinati yochezeka, cellophane ili ndi mtengo wotsika.
Kuletsa chinyontho
Matumba am'matumba amakana zinyezi ndi nthenga zamadzi, zimawapangitsa kukhala chisankho chabwino posonyeza ndi kusunga zakudya.
Kuzunza Mafuta
Mwachibadwa amakana mafuta ndi mafuta, kotero matumba a cellophane ndi abwino kwa zinthu zophika, mtedza, ndi zakudya zina zamatsenga.
Kutentha kosindikizidwa
Cellophane ndi kutentha. Ndi zida zoyenera, mutha kutentha msanga komanso kutentha zinthu zosungidwa m'matumba a cellophane.
Kodi tsogolo la ma cellulose ndi chiyani?
Tsogolo laCellulose FilimuKuyika kumawoneka owala. Lipoti la Mlendo wamtsogolo limalosera za kuwunika kwa cellulose kukhala ndi kuchuluka kwa pachaka kwa 48% pakati pa 2018 ndi 2028.
70% ya kukula kumeneku akuyembekezeka kuchitika mu chakudya ndi chakumwa. Ma diophagrad cellophane pakompyuta ndi matumba okhala ndi gulu lalikulu kwambiri.
Cellophane ndi phukusi la chakudya sikuti mafakitale okha pa cellulose amagwiritsidwa ntchito. Cellulose yavomerezedwa ndi FDA kuti mugwiritse ntchito:
Zowonjezera Zowonjezera
Misozi yopanda
Mankhwala osokoneza bongo
Chithandizo cha zilonda
Cellophane amawoneka nthawi zambiri mu chakudya ndi chakumwa, mankhwala opangira mankhwala, chisamaliro chaumwini, chisamaliro chanyumba, ndi magawo ogulitsa.
Kodi katundu wa cellulose ndiwoyenera bizinesi yanga?
Ngati mukugwiritsa ntchito matumba apulasitiki, mtedza, zinthu zophika, etc., matumba a cellophane ndi njira yabwino. Opangidwa ndi utoto wotchedwa Chilengedwe Fenflex ™ opangidwa kuchokera ku cellulose wochokera ku zamkati, matumba athu ndi amphamvu, omveka bwino komanso omveka bwino.
Timapereka masitayilo awiri a ma cellophale a cellophale mu mitundu yosiyanasiyana:
Matumba a cellophane
Matumba ophatikizika a celsehane
Timaperekanso chosindikizira dzanja, chifukwa chake mutha kutentha kumasindikiza matumba anu a cellophane.
Pamalo abwino, ndife odzipereka popereka matumba apamwamba, okonda ku Eco-ochezeka komanso pakompyuta yovuta. Ngati mukufuna kuphunzira zambiri za cellulose kapena zina zilizonse, chonde lemberani lero
PS itsimikizireni kuti mugula zikwama zanu za cello kuchokera ku zogulitsa zodziwika bwino monga phukusi labwino. Msika wambiri wa mabizinesi "wobiriwira" Cellops wopangidwa ndi pulasitiki.
