Wax kasta oo aad u baahan tahay inaad ka ogaato Baakadaha Cellulose
Haddii aad fiirineysay walxaha baakadaha u wanaagsan deegaanka, waxaa suurtogal ah inaad maqashay cellulose, oo sidoo kale loo yaqaan cellophane.
Cellophane waa shay cad oo qallafsan oo jiray ilaa horraantii 1900-yadii.Laakiin, way ku yaabin kartaa inaad barato in cellophane, ama baakadaha filimka cellulose, ay ku saleysan yihiin dhirta, la kariyo, iyo badeecad dhab ah "cagaaran".
Waa maxay baakada cellulose?
La helay 1833, cellulose waa walax ku dhex taal gidaarada unugyada dhirta.Waxay ka kooban tahay silsilad dheer oo unugyo gulukoos ah, taasoo ka dhigaysa polysaccharide (ereyga sayniska ee karbohaydrayt).
Marka dhowr silsiladood oo cellulose ah oo isku xidhan hydrogen, waxay sameeyaan wax loo yaqaan microfibrils, kuwaas oo ah kuwo aan la aqbali karin oo adag.Qallafsanaanta microfibrils-kan ayaa ka dhigaysa cellulose molecule aad u fiican oo loo isticmaalo wax soo saarka bioplastic.
Intaa waxaa dheer, cellulose waa bioopolymerka ugu badan ee adduunka oo dhan, iyo qaybo ka mid ah ayaa leh saamaynta ugu yar ee deegaanka.Inkasta oo ay jiraan noocyo kala duwan oo cellulose ah.Baakadaha cuntada cellulose caadi ahaan waa cellophane, cad, dhuuban, walxo balaastik ah oo la mid ah noolaha.
Sidee loo sameeyaa baakadaha filimada cellulose?
Cellophane waxaa laga sameeyay cellulose-ka laga soo qaado suufka, alwaax, hemp, ama ilo kale oo dabiici ah oo si joogto ah loo goostay.Waxay ku bilaabataa sida saxarka kala dirida cad, kaas oo ah 92%-98% cellulose.Kadibna, saxarka cellulose ceeriin wuxuu maraa afarta tallaabo ee soo socota si loogu beddelo cellophane.
1. cellulose-ku waxa lagu milmaa alkali (asaasiga ah, milixda ionic ee kiimikooyinka birta alkaline) ka dibna da'da dhowr maalmood.Nidaamkan kala dirida waxa loo yaqaana mercerization.
2. Kaarboon disulfide waxa lagu mariyaa saxarka meerisaysan si loo abuuro xal loo yaqaan cellulose xanthate, ama viscose.
3. Xalkan ayaa markaa lagu daraa isku dar ah sodium sulfate iyo milo sulfuric acid.Tani waxay xalku dib ugu noqotaa cellulose.
4. Kadibna, filimka cellulose wuxuu maraa saddex kale oo dhaqid ah.Marka hore in la saaro baaruudka, ka dibna si aad u nadiifiso filimka, iyo ugu dambeyntii ku dar glycerin si aad u adkeyso.
Natiijada ugu dambeysa waa cellophane, oo loo isticmaalo warshadaha baakadaha cuntada, ugu horreyn si loo abuuro bacaha cellophane biodegradable ama "bacaha cello".
Waa maxay faa'iidooyinka alaabta cellulose?
Iyadoo habka abuurista baakadaha cellulose uu yahay mid adag, faa'iidooyinku waa cad yihiin.
Dadka Maraykanku waxay isticmaalaan 100 bilyan oo bac ah sannadkii, kuwaas oo u baahan 12 bilyan oo barmiil oo saliid ah sannadkiiba.Intaa waxaa dheer, 100,000 oo xayawaan badeed ah ayaa lagu dilo bac sanad kasta.Waxay qaadataa in ka badan 20 sano in bacaha batroolka ku salaysan ay hoos u dhacaan badda dhexdeeda.Markay sameeyaan, waxay abuuraan balaastiig yaryar oo sii dhex gala silsiladda cuntada.
Marka ay bulshadeenu u korto dareenka deegaanka, waxaan sii wadeynaa raadinta bey'ada-saaxiibtinimo, noole-bedelka balaastiig-ku-saleysan batroolka.
Marka laga reebo inay noqoto beddelka caagga ah, baakadaha filimka cellulose wuxuu soo bandhigayaa faa'iidooyin badan oo deegaanka ah:
Waarta & noole ku salaysan
Sababtoo ah cellophane waxaa laga abuuray cellulose laga soo goostay dhirta, waa badeeco waara oo laga soo qaatay bio-based, kheyraad dib loo cusboonaysiin karo.
noolayn kara
Baakadaha filimka cellulose waa biodegradable.Tijaabooyinku waxay muujiyeen in baakadaha cellulose-ka-biodegrades ee 28-60 maalmood haddii alaabtu ay tahay mid aan dahaadhnayn iyo 80-120 maalmood haddii la dahaadhay.Waxa kale oo ay hoos u dhigtaa biyaha 10 maalmood gudahood haddii aanay dahaarka lahayn iyo haddii ay dahaarkaan ku dhawaad bil.
La kasban karo
Cellophane sidoo kale waa badbaado in lagu rido qashinkaaga qashinka guriga, uma baahna xarun ganacsi oo bacrin ah.
Baakadaha cuntada ayaa faa'iido leh:
Qiime jaban
Baakadaha Cellulose waxa ay jirtay ilaa 1912, waana wax ka soo baxay warshadaha waraaqaha.Marka la barbar dhigo beddelka balaastiga kale ee deegaanka-saaxiibtinimo, cellophane waxay leedahay qiime jaban.
Qoyaanka u adkaysta
Bacaha cellophane-ka biodegradable waxay iska caabiyaan qoyaanka iyo uumiga biyaha, taasoo ka dhigaysa doorasho aad u wanaagsan soo bandhigida iyo kaydinta alaabta cuntada.
Saliid u adkaysta
Waxay si dabiici ah u diidaan saliidaha iyo dufanka, markaa bacaha cellophane waxay ku fiican yihiin alaabta la dubay, lawska, iyo cuntooyinka kale ee dufanka leh.
Kulayl la xidhi karo
Cellophane waa kulayl la dabooli karo.Qalabka saxda ah, waxaad si dhakhso ah oo fudud u kululayn kartaa oo aad u ilaalin kartaa cuntooyinka lagu kaydiyo bacaha cellophane.
Waa maxay mustaqbalka baakadaha cellulose?
Mustaqbalka eefilimka cellulosebaakadu waxay u muuqataa mid dhalaalaya.Warbixinta Aragtida Suuqa Mustaqbalka ayaa saadaalisay in baakadaha cellulose ay yeelan doonaan kobaca sanadlaha ah ee isku dhafan ee 4.9% inta u dhaxaysa 2018 iyo 2028.
Boqolkiiba 70 kobacaas ayaa la filayaa inuu ka dhaco qaybta cuntada iyo cabitaanka.Filimka baakadaha cellophane-ka biodegradable iyo bacaha ayaa ah qaybta korriinka ee ugu sarreeya ee la filayo.
Baakadaha Cellophane iyo cuntada maaha kuwa kaliya ee la isticmaalo cellulose.Cellulose waxaa u ogolaatay FDA si loogu isticmaalo:
Cuntada lagu daro
Ilmo macmal ah
Daawada buuxinta
Daaweynta dhaawaca
Cellophane waxaa badanaa lagu arkaa warshadaha cuntada iyo cabitaanka, daawooyinka, daryeelka shakhsi ahaaneed, daryeelka guriga, iyo qaybaha tafaariiqda.
Baakadaha cellulose ma ku habboon yihiin ganacsigayga?
Haddii aad hadda u isticmaasho bacaha balaastikada ah nacnaca, lawska, alaabta la dubay, iwm., bacaha baakadaha cellophane ayaa ah bedel qumman.Laga sameeyay xabagta la yiraahdo NatureFlex™ oo laga sameeyay cellulose laga soo qaatay saxarka alwaax, bacahayagu waa kuwo xoog badan, cad oo cad oo la shahaadaysan karo.
Waxaan bixinaa laba nooc oo bacaha cellophane-ka biodegradable ah oo cabbirro kala duwan leh:
Bacaha cellophane fidsan
Bacaha cellophane-ga la shiiday
Waxa kale oo aanu bixinaa qalabka gacanta lagu xidho, si aad si dhakhso ah u kululayn karto bacahaaga cellophane.
Baakadaha Bilawga Wanaagsan, waxa naga go'an inaanu bixino bacaha cellophane tayo sare leh, jawi saaxiibtinimo leh iyo baakado la burburin karo.Haddii aad xiisaynayso inaad wax badan ka ogaato baakadaha filimada cellulose ama wax ka mid ah alaabadayada kale, fadlan nala soo xidhiidh maanta
PS Hubi inaad ka soo iibsatid bacaha cello alaab-qeybiyeyaal sumcad leh sida Baakaynta Bilawga Wanaagsan.Ganacsiyo badan ayaa suuq geynaya bacaha cello "cagaaran" ee laga sameeyay caaga polypropylene.
