Horumarka joogtada ah ee tignoolajiyada wax-soo-saarka dunta, in badan oo ka mid ah fiilooyinka cusub ayaa noqday alaabta ceeriin ee dunta. Maanta, waxaan inta badan ku bari doonaa tignoolajiyada aqoonsiga ee fiber polyester-ka dib loo warshadeeyay.
Waxaa la fahamsan yahay in waagii hore, iyadoo ay ugu wacan tahay la'aanta hababka kormeerka iyo awood la'aanta hay'adaha imtixaannada inay soo saaraan warbixinno tayo leh, shirkaduhu kuma raaxaysan karaan siyaasadaha qaranka ee khuseeya, isla markaana waxay keeneen jahawareer ku saabsan calaamadaynta qaar ka mid ah alaabta polyesterka.
Waa maxay faybarka dib loo warshadeeyay ee polyester (PET)?
Taasi waa, polyester-ka wasakhda ah (PET) polymer iyo polyester-ka wasakhda ah (PET) agabka dunta ayaa dib loo warshadeeyay oo laga farsameeyay fiber polyetylen terephthalate.
Erayada caadiga ah, fiber polyester-ka dib loo warshadeeyay (kadib loo tixraaco polyester-ka dib loo warshadeeyay) waxaa loola jeedaa polyester-ka dib loo warshadeeyay (sida dhalada dhalada, xumbo, xariirta qashinka, saxarka qashinka, dunta qashinka, iwm.) ee lagu sameeyay hababka dib u warshadaynta. Ester fiber.
Mabda'a Aqoonsiga
Iyada oo ku saleysan farqiga lagama maarmaanka ah ee u dhexeeya habka farsamaynta ee dib-u-warshadaynta polyester-ka iyo bikradaha polyester-ka, taas oo keeneysa sifooyin kala duwan, muunada waxaa loo farsameeyaa si waafaqsan shuruudaha la cayimay waxaana lagu tijaabiyaa koromogaraafka dareeraha ah ee waxqabadka sare. Marka loo eego farqiga u dhexeeya aagga ugu sarreeya ee muunadda hoos yimaada waqtiyo kala duwan oo haynta , Si loo gaaro ujeedada aqoonsiga tayada.
Tallaabada aqoonsiga
1. Methanolysis
2. Barar-saarid
3. Ogaanshaha chromatography dareeraha waxqabadka sare
Dareeraha daawaynta ee lagu farsameeyay kuwan 1 iyo 2 ee kor ku xusan ayaa siday u kala horreeyaan la marsiiyaa ogaanshaha chromatography dareeraha waxqabadka sare.
4. Habaynta xogta iyo aqoonsiga
Polyester-ka dib loo warshadeeyay waxay keeni doontaa isbeddel ku yimaada nuxurka iyo qaybinta silsiladaha silsiladaha makromolecular heterogeneous iyo oligomers inta lagu jiro habka diyaarinta, taas oo loo isticmaali karo saldhig u ah aqoonsiga polyester-ka dib loo warshadeeyay iyo polyester bikrad ah.
Meesha ugu sarraysa ee gaarka ah iyo macluumaadka sifaha ugu sarreeya ayaa lagu muujiyey shaxda hoose.

Eeg mustaqbalka
Korodhka isticmaalka polyester-ka iyo ka warqabka dadka ee ilaalinta deegaanka, aad iyo aad ayaa fiiro gaar ah u leh dib u warshadaynta qashinka polyesterka. Isticmaalka qashinka polyester-ka si loo soo saaro fiber polyester-ka dib loo warshadeeyay waxay yarayn kartaa kharashka, yaraynta isticmaalka saliidda, iyo hagaajinta faa'iidooyinka dhaqaale, taas oo muhiimad weyn u leh horumarinta joogtada ah ee warshadaha fiber kiimikaad.
Isla mar ahaantaana, kororka tirada polyester-ka dib loo warshadeeyay, arrinta ku saabsan beddelka polyester-ka dib loo warshadeeyay iyo polyester bikrad ah ayaa soo jiidatay dareen badan oo ka imanaya warshadaha. Isbeddelka qiimaha labada ayaa sidoo kale muujinaya xiriir wanaagsan oo gaar ah, iyo ogaanshaha farqiga u dhexeeya labada Tiknoolajiyada ayaa sii kordhaya dareenka.
