Matumba apulasitiki, omwe kale ankaonedwa kuti ndi achilendo m'zaka za m'ma 1970, lero ndi chinthu chopezeka paliponse padziko lonse lapansi. Matumba apulasitiki amapangidwa mothamanga kwambiri mpaka 1 thililiyoni imodzi chaka chilichonse. Makampani masauzande ambiri apulasitiki padziko lonse lapansi amapanga matani amatumba apulasitiki omwe amagwiritsidwa ntchito kwambiri pogula chifukwa cha kuphweka kwawo, kutsika mtengo, komanso kusavuta.
Zinyalala zamatumba apulasitiki zimapanga kuipitsa m'njira zosiyanasiyana. Zambiri zosiyanasiyana zikuwonetsa kuti matumba apulasitiki amawononga chilengedwe ndikuwononga thanzi la anthu ndi nyama m'matauni ndi kumidzi. Nkhani imodzi ndi kutayika kwa kukongola kwachilengedwe komanso kogwirizana ndi zinyalala zapulasitiki ndi kufa kwa nyama zakutchire ndi zakutchire. Izi zitha kukhala chifukwa cha kusasamalira bwino zinyalala komanso/kapena kusamvetsetsa za kuonongeka kwa matumba apulasitiki.
Kudera nkhawa kwambiri za momwe matumba apulasitiki amakhudzira chilengedwe ndi ulimi kwapangitsa kuti maboma angapo aletse izi. Ndikofunikira kwambiri kuchepetsa zovuta za zinyalala zamatumba apulasitiki chifukwa katundu wamsika amanyamulidwa m'mapepala, thonje, ndi madengu a komweko. Zamadzimadzi zimasungidwa muzitsulo za ceramic ndi galasi. Anthu ayenera kuphunzitsidwa kuti asagwiritse ntchito matumba apulasitiki m’malo mwa nsalu, ulusi wachilengedwe, ndi matumba a cellophane.
Tsopano timagwiritsa ntchito cellophane m'njira zambiri - kusunga chakudya, kusungirako, kupereka mphatso, ndi kunyamula katundu. Ndi bwino kugonjetsedwa ndi mabakiteriya kapena tizilombo tambiri, mpweya, chinyezi, ngakhale kutentha. Izi zimapangitsa kukhala njira yopitira pakuyika.
Cellophane ndi filimu yopyapyala, yowonekera komanso yonyezimira yopangidwa ndi cellulose yosinthidwanso. Amapangidwa kuchokera ku shredded matabwa zamkati, zomwe zimathandizidwa ndi caustic soda. Otchedwa viscose kenako extruded mu kusamba kuchepetsedwa sulfuric acid ndi sodium sulphate regenerate mapadi. Kenako amatsukidwa, kutsukidwa, kuyeretsedwa ndi pulasitiki ndi glycerin kuti filimuyo isawonongeke. Nthawi zambiri zokutira monga PVDC zimagwiritsidwa ntchito kumbali zonse za filimuyo kuti apereke chinyezi chabwino ndi chotchinga mpweya komanso kuti filimuyo ikhale yotentha.
Cellophane yokutidwa ndi mpweya wochepa, kukana mafuta, mafuta ndi madzi, zomwe zimapangitsa kuti zikhale zoyenera kunyamula chakudya. Imaperekanso chotchinga cha chinyezi chochepa ndipo imasindikizidwa ndi mawonekedwe ochiritsira komanso njira zosindikizira za offset.
Cellophane imatha kubwezeretsedwanso ndipo imatha kuwonongeka m'malo opangira manyowa amnyumba, ndipo imawonongeka pakangopita milungu ingapo.
Kodi ubwino wa cellophane ndi chiyani?
1.Kuyika bwino kwazinthu zazakudya kuli m'gulu la thumba la cellophane lomwe limagwiritsa ntchito. Monga avomerezedwa ndi FDA, mutha kusunga zinthu zodyedwa zomwe zili mmenemo.
Amasunga zakudya zatsopano kwa nthawi yayitali atatsekedwa ndi kutentha. Izi zimawerengedwa ngati phindu la matumba a cellophane chifukwa amawonjezera moyo wa alumali wazinthu powaletsa kumadzi, dothi, ndi fumbi.
2.Ngati muli ndi sitolo yodzikongoletsera, muyenera kuyitanitsa matumba a cellophane mochulukira chifukwa adzakuthandizani!Matumba omveka bwinowa ndi abwino kwambiri kusunga zinthu zazing'ono zodzikongoletsera m'sitolo yanu. Iwo amawateteza ku dothi ndi fumbi tinthu tating'onoting'ono ndi kulola kuwonetsera wapamwamba wa zinthu kwa makasitomala.
Matumba a 3.Cellophane ndi abwino kuti agwiritsidwe ntchito posungirako zomangira, mtedza, mabawuti, ndi zida zina. Mutha kupanga mapaketi ang'onoang'ono pakukula kulikonse ndi gulu la zida kuti muzitha kuzipeza mosavuta pakafunika.
4.Ubwino wina wa matumba a cellophane ndikuti mutha kusunga nyuzipepala ndi zolemba zina m'menemo kuti zisakhale pamadzi. Ngakhale matumba a nyuzipepala odzipatulira amapezekanso ku Bags Direct USA, pakagwa mwadzidzidzi, matumba a cellophane amakhala ngati chisankho chabwino.
5.Kukhala wopepuka ndi phindu lina la matumba a cellophane omwe samapita mosadziwika! Ndi izi, amakhala ndi malo ochepa m'malo anu osungira. Malo ogulitsa akufufuza zinthu zonyamula katundu zomwe ndizopepuka komanso zimakhala ndi malo ochepa, chifukwa chake, matumba a cellophane amakwaniritsa zolinga zonse za eni sitolo.
6.Kupezeka pamtengo wotsika mtengo kumagweranso pansi pa mapindu a matumba a cellophane. Ku Bags Direct USA, mutha kugwiritsa ntchito matumba omveka bwino awa mochulukira pamitengo yabwino kwambiri! Simuyenera kuda nkhawa ndi mtengo wamatumba a cellophane ku USA; ngati mukufuna kuyitanitsa pagulu, ingodinani ulalo womwe wapatsidwa ndikuyitanitsa nthawi yomweyo!
Kuipa Kwa Matumba Apulasitiki
Zinyalala zamapulasitiki zimayika pachiwopsezo thanzi la anthu ndi nyama chifukwa zimatayidwa padziko lonse lapansi, zomwe zimatengera malo ochulukirapo ndikutulutsa mpweya woipa wa methane ndi mpweya woipa, komanso utsi wowopsa kwambiri.
Chifukwa chakuti matumba apulasitiki amatenga nthawi yaitali kuti awonongeke, amawononga chilengedwe. Matumba apulasitiki owumitsidwa ndi dzuwa amapanga mamolekyu owopsa, ndipo kuwawotcha kumatulutsa zinthu zapoizoni mumpweya, zomwe zimayambitsa kuipitsa.
Nthawi zambiri nyama zimalakwitsa kuti matumbawo ndi chakudya ndipo zimadya ndipo zimatha kukodwa mumatumba apulasitiki ndikumira. Pulasitiki
Zikuchulukirachulukira ponseponse m'zachilengedwe zam'madzi, zomwe zimafuna kuti kuipitsidwe mwachangu m'malo okhala m'madzi am'madzi ndi am'madzi am'madzi kwadziwika posachedwa ngati vuto lapadziko lonse lapansi.
Pulasitiki ya m'mphepete mwa nyanja yotsekeredwa imawononga zombo, mphamvu, usodzi, ndi ulimi wam'madzi. Matumba apulasitiki m'nyanja ndi vuto lalikulu la chilengedwe padziko lonse lapansi. Kuchuluka kwa kuipitsidwa kochokera ku makina opangira kapena zowononga zoyendetsedwa ndi mpweya. Zinthu zomwe zimatuluka m'matumba apulasitiki zalumikizidwa ndi kuchuluka kwa kawopsedwe.
Matumba apulasitiki amawopseza moyo wapamadzi komanso waulimi. Zotsatira zake, matumba apulasitiki awononga mosadziwa zinthu zofunika zapadziko lapansi, kuphatikiza mafuta. Zokolola za chilengedwe ndi zaulimi zili pachiwopsezo. Matumba apulasitiki osafunikira m'minda amawononga ulimi, zomwe zimayambitsa kuwonongeka kwa chilengedwe.
Matumba apulasitiki ayenera kuletsedwa padziko lonse lapansi ndikusinthidwa ndi njira zina zowola pazifukwa zonsezi ndipo matumba a cellophane ndi njira ina yoyenera kukhala yosunga zachilengedwe.
Ubwino Wogwiritsa Ntchito Zikwama za Cellophane
Ngakhale kupanga mapaketi a cellulose ndizovuta, matumba a cellulose amakhala ndi maubwino angapo pamatumba apulasitiki. Kupatula kukhala cholowa m'malo mwa pulasitiki, cellophane ili ndi maubwino angapo achilengedwe.
- Cellophane ndi chinthu chokhazikika chomwe chimapangidwa kuchokera ku bio-based, zongowonjezwdwanso chifukwa chimapangidwa kuchokera ku cellulose yochokera ku zomera.Makanema a cellulose amatha kuwonongeka.
- Mapaketi opangidwa ndi cellulose osaphimbidwa amawonongeka pakati pa masiku 28-60, pomwe zokutira zimatenga masiku 80-120. Amawononga m'madzi m'masiku 10, ndipo ngati atakutidwa, amatenga mwezi umodzi.
- Cellophane ikhoza kupangidwa ndi kompositi kunyumba ndipo safuna malo ogulitsa.
- Cellophane ndi yotsika mtengo poyerekeza ndi njira zina zapulasitiki zowononga chilengedwe, zomwe zimapangidwa ndi makampani opanga mapepala.
- Matumba a cellophane a biodegradable amakhala ndi chinyezi komanso nthunzi yamadzi.
- Matumba a cellophane ndi njira yabwino kwambiri yosungiramo zakudya. Matumbawa ndi abwino kwa zowotcha, mtedza, ndi zinthu zina zamafuta.
- Matumba a cellophane amatha kusindikizidwa pogwiritsa ntchito mfuti yotentha. Mutha kutentha, kutseka ndi kuteteza zakudya m'matumba a cellophane mwachangu komanso moyenera ndi zida zoyenera.
Kuwonongeka kwa Thumba la Cellophane pa Chilengedwe
Cellophane, yomwe imadziwikanso kuti cellulose, ndi utomoni wopangidwa ndi maunyolo aatali a glucose omwe amawola kukhala shuga wosavuta. M'nthaka, mamolekyuwa amatha kuyamwa. Tizilombo tating'onoting'ono ta m'nthaka timathyola maunyolowa chifukwa chodya cellulose.
Mwachidule, cellulose amawola kukhala mamolekyu a shuga omwe tizilombo tating'onoting'ono ta m'nthaka timangodya ndi kugayidwa. Zotsatira zake, kuwonongeka kwa matumba a cello sikukhudza chilengedwe kapena zamoyo zosiyanasiyana.
Njira yowola ya aerobic imeneyi imapanga, komabe, imatulutsa mpweya woipa, womwe ukhoza kubwezeretsedwanso ndipo sukhala ngati chinthu chotayika. Mpweya woipa wa carbon dioxide ndi mpweya woipa umene umapangitsa kuti dziko litenthe.
