Iyadoo horumarka joogtada ah ee tiknoolajiyada wax soo saarka dharka uu socdo, fiilooyin cusub oo badan ayaa noqday walxo ceeriin ah oo loogu talagalay dharka. Maanta, waxaan inta badan ku soo bandhigi doonaa tiknoolajiyada aqoonsiga fiilooyinka polyester-ka ee dib loo warshadeeyay.
Waxaa la fahansan yahay in waagii hore, iyadoo ay ugu wacan tahay la'aanta hababka kormeerka iyo awood la'aanta hay'adaha baaritaanka inay soo saaraan warbixinno tayo leh, shirkaduhu ma aysan ku raaxaysan karin siyaasadaha qaranka ee khuseeya, isla markaana ay jahawareer ku abuurtay calaamadaynta qaar ka mid ah alaabada polyester-ka.
Waa maxay faybarka polyester-ka dib loo warshadeeyay (PET)?
Taas macnaheedu waa, walxaha dharka ee polyester-ka qashinka ah (PET) iyo polyester-ka qashinka ah (PET) ayaa dib loo warshadeeyaa oo loo farsameeyaa faybar polyethylene terephthalate ah.
Marka loo eego dadka caadiga ah, faybarka polyester-ka ee dib loo warshadeeyay (oo hadda loogu yeero polyester-ka dib loo warshadeeyay) waxa loola jeedaa polyester-ka dib loo warshadeeyay (sida jajabyada dhalada, xumbo, xariir qashin ah, saxarka qashinka, dharka qashinka ah, iwm.) oo ay sameeyeen hababka dib-u-warshadaynta. Faybarka Ester.
Mabda'a Aqoonsiga
Iyada oo ku saleysan farqiga muhiimka ah ee u dhexeeya habka farsamaynta ee polyester-ka dib loo warshadeeyay iyo polyester-ka bikrada ah, kaas oo keena astaamo kala duwan, muunadda waxaa loo farsameeyaa iyadoo loo eegayo xaaladaha la cayimay waxaana lagu tijaabiyaa chromatograph dareere ah oo waxqabad sare leh. Sida waafaqsan farqiga u dhexeeya aagga ugu sarreeya ee muunadda iyadoo la raacayo waqtiyada kaydinta kala duwan, Si loo gaaro ujeeddada aqoonsiga tayada.
Tallaabada Aqoonsiga
1. Metanolysis
2. Barar-Soo-saarid
3. Ogaanshaha koromatografiga dareeraha ah ee waxqabadka sare leh
Dareeraha daaweynta ee lagu farsameeyay 1 iyo 2 ee kor ku xusan waxaa si kala duwan loogu sameeyaa ogaanshaha koromatografiga dareeraha ee waxqabadka sare leh.
4. Habaynta iyo aqoonsiga xogta
Polyester-ka dib loo warshadeeyay wuxuu sababi doonaa isbeddelo ku yimaada nuxurka iyo qaybinta isku xirka silsiladda isku dhafan ee macromolecular iyo oligomers inta lagu jiro habka diyaarinta, kuwaas oo loo isticmaali karo saldhig ahaan si loo aqoonsado polyester-ka dib loo warshadeeyay iyo polyester-ka bikrada ah.
Macluumaadka ugu sarreeya goobta gaarka ah iyo astaamaha ugu sarreeya waxaa lagu muujiyey jadwalka hoose.

Mustaqbalka eeg
Iyadoo ay sii kordheyso isticmaalka polyester-ka iyo wacyigelinta dadku ee ku aaddan ilaalinta deegaanka, waxaa sii kordhaya fiiro gaar ah loo yeelanayaa dib-u-warshadaynta qashinka polyester-ka. Isticmaalka qashinka polyester-ka si loo soo saaro faybar polyester-ka dib loo warshadeeyay wuxuu yareyn karaa kharashyada, yareyn karaa isticmaalka saliidda, wuxuuna wanaajin karaa faa'iidooyinka dhaqaale, taas oo muhiimad weyn u leh horumarka waara ee warshadaha kiimikada ee fiber-ka.
Isla markaana, iyadoo ay sii kordhayaan tirada polyester-ka dib loo warshadeeyay, arrinta beddelka polyester-ka dib loo warshadeeyay iyo polyester-ka bikrada ah ayaa soo jiidatay dareen badan oo ka imanaya warshadaha. Isbeddelka qiimaha ee labada ayaa sidoo kale muujinaya isku xirnaan wanaagsan, ogaanshaha farqiga u dhexeeya labada tiknoolajiyaduna waxay sii kordhinaysaa dareenka.
