Qalabka wax lagu xiro ee xannibaadda sare ayaa si degdeg ah loo sameeyay waxaana si ballaaran loogu isticmaalay warshadaha baakadaha gaar ahaan warshadaha baakadaha cuntada.Waxay door ka ciyaartaa ilaalinta tayada cuntada, dhawrista cusub, ilaalinta dhadhanka iyo kordhinta nolosha shelf.Waxaa jira teknoolojiyad kala duwan oo loogu talagalay ilaalinta cuntada, sida baakadaha faakuumka, baakadaha barokaca gaaska, xirida baakadaha deoxidizer, baakadaha qalajinta cuntada, baakadaha buuxinta aseptic, baakadaha karinta, baakadaha buuxinta kulaylka dareeraha ah iyo wixii la mid ah.Qaar badan oo ka mid ah teknoolojiyaddan baakadaha, alaabada baakadaha caagga ah ee xannibaadda wanaagsan waa in la isticmaalo.
Walxaha filimada caqabada sare ee caadiga ah waa sida soo socota:
1. Qalabka PVDC (Polyvinylidene Chloride)
Polyvinylidene chloride (PVDC) xabagta, oo inta badan loo isticmaalo sida walxo isku dhafan ama walxo monomer ah iyo filim la sii daayay, ayaa ah alaabta ugu badan ee la isticmaalo baakadaha xannibaadaha.Isticmaalka filimka dahaarka leh ee PVDC ayaa si gaar ah u weyn.Filimka dahaarka leh ee PVDC waa isticmaalka polypropylene (OPP), polyetylen terephthalate (PET) oo ah walxaha aasaasiga ah.Sababtoo ah heerkulka jilcinta sare ee PVDC saafiga ah, milanka PVDC wuxuu ku dhow yahay heerkulkiisa kala-goynta, iyo miscibility ee caagagga guud waa liidata, qaabaynta kuleylku way adag tahay oo ay adagtahay in si toos ah loo mariyo.Isticmaalka dhabta ah ee filimka PVDC inta badan waa copolymer of vinylidene chloride (VDC) iyo vinyl chloride (VC), iyo sidoo kale acrylic methylene (MA) copolymerization oo ka samaysan filim gaar ah oo caqabad ku ah.
2. Alaabta Baakadaha nylon
Qalabka baakadaha nylon ka hor - isticmaal toos ah "nylon 6".Laakiin cidhiidhiga hawada "nylon 6" maaha mid ku habboon.Nayloon (MXD6) oo laga sameeyay polycondensation m-dimethylamine iyo adipic acid ayaa 10 jeer ka badan hawo-mareenka "nylon 6", iyadoo sidoo kale leh daahfurnaan wanaagsan iyo iska caabin dalool.Inta badan waxaa loo isticmaalaa filimka baakadaha xayndaabka sare shuruudaha xannibaadaha sare ee baakadaha dabacsan ee cuntada.Waxa kale oo ay FDA u ogolaatay nadaafadda cuntada.Muuqaalkeeda ugu weyn ee filim ahaan waa in xannibaadda aysan ku dhicin kor u kaca qoyaanka.Yurub dhexdeeda, MXD6 naylon waxaa si weyn loogu isticmaalaa beddelka filimada PVDC sababo la xiriira ilaalinta deegaanka ee caanka ah.
3. Qalabka EVOH
EVOH waa walaxda ugu badan ee la isticmaalo xannibaadyada sare.
Noocyada filimka ee walxahan marka lagu daro nooca aan fiicneyn, waxaa jira nooc laba-jibbaaran, nooca uumiga aluminium, nooca dhejiska iyo wixii la mid ah.Laba-dariiqa fidinta iyo kulaylka - alaabada u adkaysata baakadaha aseptic.
4. Filimka Dahaarka ah ee oksaydhisku
PVDC, oo si weyn loogu isticmaalo baakadaha xannibaadda sare, waxay u janjeertaa in lagu beddelo baakadaha kale sababtoo ah qashinka ayaa soo saari doona HCl marka la gubo.Tusaale ahaan, waxa loogu yeero filimka dahaarka ah ee la sameeyay ka dib markii la daboolay SiOX (silicon oxide) ee filimka substrates kale ayaa la siiyay fiiro gaar ah, marka lagu daro filimka silikoon oxide, waxaa jira filimka uumiga aluminium.Waxqabadka gaas-ku-dhuuban ee dahaarka ayaa la mid ah kan daboolka silikoon oxide ee lagu helay hab isku mid ah.
Sannadihii ugu dambeeyay, isku-dhafka lakabka badan, isku-dhafka, koolymerization-ka iyo tignoolajiyada uumiga ayaa si degdeg ah u horumaray.Qalabka baakadaha sare sida vinyl vinyl glycol copolymer (EVOH), chloride polyvinylidene (PVDC), polyamide (PA), polyetylene terephthalate (PET) walxaha isku dhafan ee isku dhafan iyo filimka uumiga silikoon oxide ayaa la sii horumariyay, gaar ahaan alaabooyinka soo socda ayaa aad u badan. indho-qabasho: Qalabka baakadaha MXD6 polyamide;Polyethylene glycol naphthalate (PEN);Filimka uumiga Silicon oxide, iwm.
