Iifilimu zePVC ezithambileyoZisetyenziswa kakhulu ekupakisheni, kwizinto zokuhombisa, nakwizicelo zeefilimu ezikhuselayo, ezithandwa ngabavelisi ngenxa yokuguquguquka kwazo okubalaseleyo, ukucaca okuphezulu kokukhanya, kunye nemveliso yobuninzi engabizi kakhulu. Nangona kukho iindlela zokusebenza ezisemgangathweni zokucubungula, iifektri ezininzi ziyasokola ngenxa yeziphene zomgangatho eziphindaphindayo ngexesha lemveliso kunye nokugcinwa kweendawo zokugcina izinto ixesha elide, kubandakanya ukufiphala komphezulu, ukuna kwempuphu emhlophe, kunye nokunamathela komphezulu okuqhubekayo. Ezi ngxaki zincinci kodwa zinzima ziyayiphazamisa indlela ifilimu ebonakala ngayo kunye nokuguda komphezulu, okuhlala kukhokelela kumgangatho ongaguqukiyo webhetshi, izikhalazo zabathengi, kunye nenkunkuma yemveliso engeyomfuneko.
Uninzi lweengcali zemveliso zihlala zithi ezi ntsilelo zibangelwa ziiplastiki ezingasebenzi kakuhle okanye useto lobushushu olungafanelekanga. Nangona kunjalo, ukuphinda-phinda ukulungisa iifomyula kwindawo kunye nokuqinisekiswa kwemizi-mveliso kuqinisekisa ukuba ukungangqinelani phakathi kweziqinisi eziqhelekileyo kunye neenkqubo zeplastiki yeyona nto iphambili. Nokuba kukho iiplastiki zezinga eliphezulu kunye neeparameters zokucubungula ezichanekileyo, iziqinisi ezingahambelani kakuhle zibangela ukwahlukana kwesigaba okuqhubekayo kunye nokufuduka kokongeza.
Kutheni Kukho Ukuna Nokugquma Kwiindawo Zefilimu Ezithambileyo ZePVC
Ngokungafaniyo neemveliso zePVC eziqinileyo, iifilimu zePVC ezithambileyo nezicacileyo zixhomekeke kwiiplastiki zolwelo ezinemithwalo ephezulu ukuze zifezekise ubume obuguquguqukayo kunye nokuhanjiswa kokukhanya okugqwesileyo. Ukuze kugcinwe ukusebenza okuzinzileyo kwexesha elide, yonke inkqubo yefomula ifuna ukungafani okufanayo kunye nokuhlanganiswa kweemolekyuli okulinganayo phakathi kwezongezo kunye nezinto ezisisiseko. Iziqinisi zemveli ezihlanganisiweyo eziqinileyo kunye neziqinisi ze-calcium-zinc eziqhelekileyo zibonisa ukunyibilika okuncinci kweemolekyuli kwiindawo zeplastiki yolwelo, nto leyo ebenza babe sengozini yokusasazeka okungalinganiyo ngexesha lokuxuba kunye nokucubungula.
Ngexesha lokukhupha nokuvelisa iikhalenda kubushushu obuphezulu, izinto ezizinzisa ukungahambelani azikwazi ukudibana ngokupheleleyo neeplastiki, nto leyo eshiya ii-micro-particles ezingazinzanga zibambeke ngaphakathi kwi-matrix yefilimu. Ngokuhamba kwexesha, okanye phantsi kweemeko zokugcina ubushushu nomswakama ezitshintshatshintshayo, ezi zongezo zingazinzanga zihamba kancinci ziye kumphezulu wefilimu. Iintsalela ezifudukayo zenza umaleko wenkungu ofipheleyo onciphisa ukucaca kokukhanya, iidiphozithi ezimhlophe zomgubo ezonakalisa ukufana komphezulu, kunye neentsalela ezinamathelayo ezithintela iinkqubo zokucubungula emva kokwenziwa ezifana ne-lamination, ukuprinta, kunye nokubopha.
Iifilimu zePVC ezicacileyo zinovelwano ngakumbi kwiziphene ezinjalo zokuhambelana kunezinye iindlela ezinemibala okanye ezi-matte. Ngaphandle kwemibala okanye ii-matte coatings zokufihla iziphene ezincinci, nokuba ukufuduka okuncinci kwezongezo kunokubangela ukuwohloka komgangatho okubonakalayo. Ngenxa yesi sizathu, ukwenza ngcono i-stabilizer kunye ne-plasticizer kuhambelana linyathelo eliyimfuneko lokuqinisekisa ukuveliswa kwefilimu yePVC ethambileyo necacileyo efanelekileyo nekumgangatho ophezulu.
Indlela Ukungahambelani kweStabilizer Plasticizer Okonakalisa Ngayo Umgangatho weFilimu yePVC
Ifomula ye-PVC ethambileyo eqinileyo isebenza njengenkqubo elungeleleneyo: iiplastiki zinika ukuguquguquka kunye nokuguquguquka, ngelixa iziqinisi zicinezela ukuwohloka kobushushu kunye nokwaluphala ngexesha lokucubungula kunye nobomi benkonzo. Iziqinisi eziqinileyo eziqhelekileyo kunye neziqinisi ezihlanganisiweyo ezingabizi kakhulu azinawo umsebenzi owaneleyo weemolekyuli kunye nokusebenza kokusasazwa ukuze zihambelane neeplastiki ezisebenzayo kakhulu, ziphula ibhalansi yefomyula yangaphakathi.
Uhlengahlengiso oluncinci kubushushu bokucubungula, ixesha lokuxukuxa, okanye umthamo weplastiki unokugquma iingxaki zomphezulu okwethutyana. Olu hlengahlengiso olungaphezulu alunakuphelisa umngcipheko wokwahlulwa kwesigaba esisisiseko, oko kuthetha ukuba inkungu kunye nemvula ziya kuvela kwakhona ngexesha lokugcina ixesha elide kunye nokusetyenziswa kokugqibela, nto leyo ebangela umgangatho ongaqinisekanga webhetshi. Ukutshintsha iziqinisi eziqinileyo ezingahambelaniyo neenkqubo zozinzisi zolwelo ezihambelanayo kakhulu yindlela ethembekileyo yokuvala uzinzo lwefomula kunye nokuthintela ukungaphumeleli komgangatho okuphindaphindiweyo.
Ii-Liquid BaZn kunye nee-KZn Stabilizers: Izisombululo eziLungileyo zeeFilimu ze-PVC ezicacileyo
Iingcalii-BaZn engamanzi (i-barium zinc)kwayeIziqinisi ze-KZn (potassium zinc)Zenzelwe ngokukodwa ukuveliswa kwefilimu ethambileyo ye-PVC ecacileyo kakhulu, zisombulula ngokugqibeleleyo iingxaki zokuhambelana kweziqinisi zemveli. Ezine-fluidity ephezulu kunye nokusasazwa kweemolekyuli, eziizinto zokuqinisa ulweloxuba ngokufanayo nazo zonke iintlobo zeplastiki eziqhelekileyo kumjikelo omfutshane wokuxuba, zenze inkqubo yefomula ezinzileyo kakhulu, ehambelanayo engenalo ulwahlulo olungalinganiyo.
Kwiimeko zokuvelisa ngobuninzi, iziqinisi ze-BaZn kunye ne-KZn zibonelela ngeenzuzo ezintathu ezahlukeneyo zokwenza ifilimu ye-PVC ecacileyo.
