1. Yintoni iphepha le-PVC eliqinileyo?
Igama elipheleleyo lephepha eliqinileyo le-PVC yiphepha eliqinileyo le-polyvinyl chloride. Iphepha le-PVC eliqinileyo liyi-polymer eyenziwe nge-vinyl chloride njengezinto eziluhlaza, kunye neziqinisi, izinto zokuthambisa kunye nezizalisi ezongeziweyo. Ine-antioxidant ephezulu kakhulu, i-asidi enamandla kunye nokumelana nokunciphisa, amandla aphezulu, uzinzo oluhle kakhulu kunye nokungatsha, kwaye inokumelana nokugqwala okubangelwa kukutshintsha kwemozulu. Amaphepha aqinileyo e-PVC aqhelekileyo aquka amaphepha e-PVC acacileyo, amaphepha amhlophe e-PVC, amaphepha amnyama e-PVC, amaphepha e-PVC anemibala, amaphepha e-PVC angwevu, njl.
2. Yintoni inzuzo yephepha le-PVC eliqinileyo?
Iiphepha zePVC eziqinileyo zinezibonelelo ezininzi ezifana nokumelana nokugqwala, ukungatshi, ukugquma, kunye nokumelana nokuxinana kwe-oxidation. Ukongeza, zinokuphinda zicutshungulwe kwaye zibe neendleko eziphantsi zemveliso. Ngenxa yokusetyenziswa kwazo okubanzi kunye namaxabiso afikelelekayo, zihlala ziyinxalenye yemarike yeephepha zeplastiki. Okwangoku, itekhnoloji yokuphucula kunye noyilo lwelizwe lethu lweephepha zePVC ifikelele kwinqanaba eliphambili lamazwe ngamazwe.
3. Zisetyenziselwa ntoni iiphepha zePVC?
Iiphepha zePVC zinokuguquguquka kakhulu, kwaye kukho iintlobo ezahlukeneyo zeephepha zePVC, ezifana neephepha zePVC ezicacileyo, iiphepha zePVC eziqandisiweyo, iiphepha zePVC eziluhlaza, ii-PVC sheet rolls, njl. Ngenxa yokusebenza kakuhle kokucubungula, iindleko eziphantsi zokuvelisa, ukumelana nokugqwala kunye nobushushu. Iiphepha zePVC zisetyenziswa kakhulu kwaye zisetyenziselwa kakhulu ukuvelisa: Iikhava zokubopha zePVC, amakhadi ePVC, iifilimu eziqinileyo zePVC, iiphepha zePVC eziqinileyo, njl.
4. Zithini iingxaki zephepha lePVC?
Iphepha lePVC likwayiplastiki esetyenziswa kakhulu. Liyi-resin eyenziwe yi-polyvinyl chloride resin, i-plasticizer, kunye ne-antioxidant. Ayinabungozi ngokwayo. Kodwa izinto ezincedisayo eziphambili ezifana ne-plasticizers kunye ne-antioxidants ziyingozi. Ii-plasticizers kwi-PVC sheet plastiki zemihla ngemihla zisebenzisa kakhulu i-dibutyl terephthalate kunye ne-dioctyl phthalate. Ezi khemikhali ziyingozi. I-antioxidant lead stearate esetyenziswa kwiPVC nayo iyingozi. Iiphepha zePVC ezinetyuwa ye-lead antioxidants ziya kuthintela i-lead xa zidibana nezinyibilikisi ezifana ne-ethanol kunye ne-ether. Iiphepha zePVC ezine-lead zisetyenziselwa ukupakisha ukutya. Xa zidibana nezinti zentlama eqhotsiweyo, iikeyiki eziqhotsiweyo, iintlanzi eziqhotsiweyo, iimveliso zenyama ephekiweyo, ii-pastries kunye ne-snacks, njl.njl., iimolekyuli ze-lead ziya kusasazeka ziye kwioyile. Ke ngoko, iingxowa zeplastiki zePVC azinakusetyenziselwa ukugcina ukutya, ngakumbi ioyile yokutya. Ukongeza, iimveliso zeplastiki zepolyvinyl chloride ziya kubola kancinci igesi yehydrogen chloride kumaqondo obushushu aphezulu, afana nama-50°C, ayingozi emzimbeni womntu.
5. Ingaba ukutya kwephepha lePVC kukhuselekile?
Iphepha le-PVC linokuba likhuselekile ekutyeni, kodwa kuphela xa lenziwe kusetyenziswa izixhobo ze-PVC ezikumgangatho wokutya kunye nezongezo ezihambelanayo. Amaphepha e-PVC akumgangatho wokutya awabi natyhefu, akanavumba, kwaye afanelekile ekudibaneni ngokuthe ngqo okanye ngokuthe ngqo kokutya, kuxhomekeke kwifom kunye nokusetyenziswa kwawo.
Amaphepha e-PVC akhuselekileyo ekutyeni asetyenziswa kakhulu ekupakisheni ukutya, ekupakisheni iiblister, kwiifilimu zokuncamathela, kwiitreyi zokutya, nakwiikhava zokukhusela. Anika ukumelana okuhle kweekhemikhali, ukucaca, kunye neempawu zokuthintela, okwenza ukuba afaneleke kwizicelo ezininzi ezinxulumene nokutya.
Nangona kunjalo, ayizizo zonke iiphepha ze-PVC ezikhuselekileyo ekutyeni. Amaphepha e-PVC akumgangatho wezoshishino anokuba neeplastiki okanye izongezo ezingavunyelwanga ukuba zidibane nokutya. Ukuqinisekisa ukhuseleko, soloko uqinisekisa ukuba iphepha le-PVC liyahlangabezana nemigaqo yoqhagamshelwano lokutya ye-FDA, EU (EC), kwaye ucele iziqinisekiso zokhuseleko lwezinto ezivela kumenzi.
6.Ingaba i-PVC Sheet Flame ayisebenzi kakuhle?
Ewe, iphepha le-PVC liyakwazi ukuthintela amalangatye ngokwendalo xa lithelekiswa nezinye izinto ezininzi zeplastiki. Ngenxa yokuba liphezulu kwi-chlorine, i-PVC iyazicima ngokwayo xa umthombo welangatye langaphandle ususiwe, nto leyo enciphisa kakhulu ukusasazeka komlilo.
Amaphepha e-PVC asetyenziswa rhoqo kwiindawo apho ukhuseleko lomlilo lubalulekile, njengezinto zokwakha, iiphaneli zodonga, ubushushu bombane, imiqondiso, kunye neendawo zokuvala zoshishino. Kwiimeko ezininzi, amaphepha e-PVC anokufikelela kwimigangatho yamazwe ngamazwe yokuthintela amalangatye efana ne-UL94 V-0 / V-1 okanye efanayo, kuxhomekeke kwifom.
Kwiiprojekthi ezineemfuno ezingqongqo zokhuseleko lomlilo, amaphepha e-PVC athintela amalangatye anokusebenza okuphuculweyo anokwenziwa ngokwezifiso ukuze ahlangabezane neekhowudi ezithile zokwakha kunye nemigangatho yokumelana nomlilo.
