1, hordhaca filimka polyester-ka

Filimka Polyester-ka waxaa sidoo kale loo yaqaannaa filimka polyester-ka (PET) (filim iftiin, filim polyester ah, warqad xasaasi ah, filim polyester ah, filim tin benzene, cellophane, filim sii daayo), waa terephthalate polyetylen ah sida alaabta ceeriin, isticmaalka habka extrusion galay filim qaro weyn, ka dibna fidin laba jiho ah oo ka samaysan walxo filim.

Filimka polyester-ka ee gudaha (filim polyester-ka, filimka ilaalinta deegaanka, filimka PET, filimka opal iyo alaabada kale ee daabacaadda iyo baakadaha), oo si ballaaran loo isticmaalo fiber galaas ah oo la xoojiyay warshadaha caaga ah, warshadaha qalabka dhismaha, warshadaha daabacaadda, daawada iyo caafimaadka.

Waqtigan xaadirka ah, Shiinuhu wuxuu si guul leh u sameeyay filim qalloocan PET, kaas oo aan sun ahayn, midab lahayn, hufan, qoyaan u adkaysta, neefta, jilicsan, xoog leh, dufan acid-alkali ah iyo dareeraha u adkaysta, oo aan ka baqin heerkulka sare iyo hoose.Ma yahay wax aan sun ahayn, oo daah-furan oo dib loo warshadayn karo, oo inta badan loo isticmaalo cabitaanno kala duwan, biyaha macdanta iyo baakadaha filimada, ayaa hadda si weyn looga isticmaalaa adduunka mid ka mid ah alaabta baakadaha.

Filimka Mylar waa nooc ka mid ah filim caag ah oo polymer ah, sababtoo ah sifooyin dhammaystiran oo heer sare ah oo aad iyo aad u badan oo ay jecel yihiin macaamiisha intooda badan.Maadaama heerka wax soo saarka Shiinaha iyo heerka farsamada uusan weli dabooli karin baahida suuqa, qaar ayaa weli u baahan inay ku tiirsanaadaan soo dejinta.

2, hantida filimka polyesterka

PET waa polymer sare, oo ka dhalata fuuq-baxa ethylene terephthalate.Glycol terephthalate waxaa lagu helaa esterification of terephthalic acid iyo glycol.PET waa caddaan caano ah ama huruud khafiif ah, polymer crystalline aad u sarreeya oo leh siman, dhalaal badan.

PET waxay leedahay sifooyin aad u fiican (iska caabin kulaylka, caabbinta kiimikada).Xoog iyo adayg, dahaarka korantada, badbaadada, iwm), raqiis ah, si ballaaran loo isticmaalo sida fiber, filim, balaastikada injineernimada, dhalooyinka polyesterka iyo wixii la mid ah.

PET waxay leedahay sifooyin jidheed iyo farsamo aad u wanaagsan oo heerkul balaadhan ah, heerkulka isticmaalka muddada dheer ilaa 120 ℃, dahaarka korantada aad u fiican, xitaa heerkulka sare iyo soo noqnoqda sare, sifooyinka korontadu wali waa wanaagsan yihiin, laakiin caabbinta korona liidata, sunta ka hortagga , Cimilada iska caabinta, xasilloonida caabbinta kiimikada, gurguurta, caabbinta daalka, iska caabinta khilaafka, xasilloonida cabbirka ayaa aad u wanaagsan.Nuugista biyaha hooseeya, caabbinta asiidhyada daciifka ah iyo dareerayaasha organic, laakiin aan kulaylka u adkeysi lahayn dhexgalka biyaha, ma caabbinta alkali.

Caadi ahaan PET waa mid aan midab lahayn, filim dhalaalaya (qaybaha wax lagu daro ayaa hadda lagu dari karaa si ay u yeeshaan midab), sifooyin farsamo oo aad u fiican, qallafsanaan sare, qallafsanaan iyo adkaan, iska caabin dalool, iska caabin khilaaf, heerkulka sare iyo iska caabinta heerkulka hooseeya, caabbinta kiimikada, saliid iska caabin, cidhiidhi hawo iyo ilaalinta udgoonka, waa mid ka mid ah waxyaabaha sida caadiga ah loo isticmaalo ka-hortagga dhexgalka filimada substrates, laakiin caabbinta korona ma wanaagsana.
