I-Thermoplastic Polymer

I-polymer ye-thermoplastic wuhlobo lwepulasitiki olungancibilika futhi lubunjwe kabusha izikhathi eziningi ngaphandle koshintsho olukhulu lwamakhemikhali. Lesi sakhiwo singenxa yokuthi ama-polymers we-thermoplastic akhiwe ngamaketanga amade we-repeamayunithi okulinganisa abizwa ngokuthi ama-monomers, ahlanganiswe ndawonye amandla abuthakathaka e-intermolecular.

Ama-polymers we-Thermoplastic asetshenziswa kabanzi ezimbonini eziningi, kufaka phakathi ezezimoto, ezokwakha, zokupakisha, nokunakekelwa kwezempilo. Zikhethwa kunezinye izinhlobo zamapulasitiki ngoba kulula ukucutshungulwa futhi zibunjwe, futhi zingakhiqizwa ngobuningi ngenani eliphansi kakhulu.

Enye yezinzuzo eziyinhloko ze-polymer ye-thermoplastic yikhono layo lokubunjwa libe yizimo eziyinkimbinkimbi nezakhiwo. Lokhu kufezwa ngokushisisa i-polymer ezingeni lokushisa elingaphezu kwendawo yayo yokuncibilika, okwenza amandla e-intermolecular abe buthaka futhi i-polymer ibe uketshezi kakhulu. Uma i-polymer isifinyelele ukuvumelana okufiswayo, ingabunjwa ibe yisimo esifiswayo kusetshenziswa izindlela ezahlukahlukene, okuhlanganisa ukubumba komjovo, i-extrusion, kanye nokubunjwa kokushaywa.

Enye inzuzo ye-polymer ye-thermoplastic yikhono layo lokuphinda lisetshenziswe futhi lisetshenziswe kabusha. Ngenxa yokuthi angancibilika futhi abunjwe kabusha izikhathi eziningi ngaphandle koshintsho olukhulu lwamakhemikhali, ama-polymers we-thermoplastic angaphinda asetshenziswe futhi asetshenziselwe ukwenza imikhiqizo emisha. Lokhu kunciphisa imfucuza futhi konga izinsiza, okwenza ama-polymer ashisayo abe inketho evumelana nemvelo kunezinye izinhlobo zamapulasitiki.

Kunezinhlobo eziningi ezahlukene zama-polymers we-thermoplastic, ngayinye enezici zayo nezici ezihlukile. Amanye ama-polymers asetshenziswa kakhulu e-thermoplastic afaka i-polyethylene, i-polypropylenei-polystyrene, i-polyvinyl chloride (PVC).

• I-Polyethylene iyipulasitiki engasindi, eguquguqukayo, futhi ehlala isikhathi eside evame ukusetshenziswa ekufakweni, ekwakheni nasezintweni zezimoto. Iyakwazi ukumelana nomswakama kanye namakhemikhali, okwenza ilungele ukusetshenziswa ezindaweni lapho lezi zici zikhona.
• I-Polypropylene iyipulasitiki eqinile futhi eqinile evame ukusetshenziswa ezimotweni, ekupakisheni, nasezintweni zokwakha. Inezinga eliphezulu lokuncibilika, okuyenza imelane nokushisa namakhemikhali.
• I-Polystyrene iyipulasitiki engasindi futhi eqinile evame ukusetshenziswa ekupakisheni, ekufakeni izinto nasezimpahleni zabathengi. Kuyi-insulator enhle futhi imelana nomswakama kanye namakhemikhali.
• PVC ipulasitiki enemisebenzi eminingi evame ukusetshenziswa ekwakheni, ekunakekelweni kwezempilo, nasezimpahleni zabathengi. Iyavumelana nezimo, ihlala isikhathi eside, futhi imelana nomswakama kanye namakhemikhali.

Kafushane, ama-polymer e-thermoplastic ayikilasi lezinto zepulasitiki ezingancibilika futhi zibunjwe kabusha izikhathi eziningi ngaphandle koshintsho olukhulu lwamakhemikhali. Asetshenziswa kakhulu ezimbonini eziningi ngenxa yokusebenziseka kalula, amandla okubunjwa abe yizimo eziyinkimbinkimbi, kanye nokusetshenziswa kabusha. Kunezinhlobo eziningi ezahlukene zama-polymers we-thermoplastic, ngayinye enezici zayo nezici ezihlukile.
