Thermoplastic Polymer

I-polymer ye-thermoplastic luhlobo lweplastiki enokuthi inyibilikiswe kwaye ibunjwe kwakhona amaxesha amaninzi ngaphandle kokwenza naluphi na utshintsho olubalulekileyo lweekhemikhali. Le propati ngenxa yokuba iipholima ze-thermoplastic zenziwe ngamatyathanga amade e-repeiiyunithi zokutya ezibizwa ngokuba zii-monomers, ezibanjwa kunye ngamandla abuthathaka e-intermolecular.

Iipolymers zeThermoplastic zisetyenziswa ngokubanzi kumashishini amaninzi, kubandakanya iimoto, ulwakhiwo, ukupakishwa, kunye nokhathalelo lwempilo. Zikhethwa ngaphezu kwezinye iindidi zeeplastiki kuba kulula ukuzilungisa nokungunda, kwaye zinokuveliswa ngobuninzi ngexabiso eliphantsi.

Enye yeenzuzo eziphambili zepolymer ye-thermoplastic kukukwazi ukubunjwa kwiimilo ezinzima kunye nezakhiwo. Oku kuphunyezwa ngokufudumeza i-polymer kwiqondo lokushisa ngaphezu kwendawo yokunyibilika kwayo, okubangela ukuba amandla e-intermolecular abe buthathaka kwaye i-polymer ibe yinto eninzi yamanzi. Nje ukuba i-polymer ifikelele kwimo enqwenelekayo, inokubunjwa ibe kwimilo efunekayo kusetyenziswa iindlela ezahlukeneyo, kubandakanya ukubumba inaliti, i-extrusion, kunye nokubumba ukuvuthela.

Enye inzuzo yepolymer ye-thermoplastic kukukwazi ukuphinda isetyenziswe kwaye isetyenziswe kwakhona. Ngenxa yokuba zinokunyibilikiswa kwaye ziphinde zenziwe amatyeli amaninzi ngaphandle kotshintsho olubalulekileyo lweekhemikhali, iipolymers ze-thermoplastic zinokuphinda zisetyenziswe kwaye zisetyenziselwa ukwenza iimveliso ezintsha. Oku kunciphisa inkunkuma kunye nokugcina izibonelelo, ukwenza iipholima ze-thermoplastic zibe yindlela ehambelana nokusingqongileyo kunezinye iindidi zeplastiki.

Kukho iintlobo ezininzi ezahlukeneyo zeepolymers ze-thermoplastic, nganye ineempawu zayo kunye neempawu zayo. Ezinye zeepolymers ze-thermoplastic ezisetyenziswa ngokuqhelekileyo ziquka i-polyethylene, polypropylenei-polystyrene, kunye ne-polyvinyl chloride (PVC).

• I-Polyethylene yiplastiki ekhaphukhaphu, eguquguqukayo, kwaye ehlala ihleli esetyenziswa ngokuqhelekileyo ekupakisheni, ekwakhiweni nasekufakweni kweemoto. Iyakwazi ukumelana nokufuma kunye neekhemikhali, okwenza kube yinto efanelekileyo yokusetyenziswa kwiindawo apho ezi zinto zikhona.
• I-Polypropylene yiplastiki eyomeleleyo kwaye eqinile edla ngokusetyenziswa kwiimoto, ukupakisha, kunye nezicelo zokwakha. Inomgangatho ophezulu wokunyibilika, okwenza ukuba ikwazi ukumelana nobushushu kunye neekhemikhali.
• I-Polystyrene yiplastiki ekhaphukhaphu kwaye eqinile edla ngokusetyenziswa ukupakisha, ukugquma, kunye nempahla yabathengi. Yi-insulator efanelekileyo kwaye iyamelana nokufuma kunye neekhemikhali.
• PVC yiplastiki enemisebenzi emininzi edla ngokusetyenziswa kulwakhiwo, kukhathalelo lwempilo, nakwimpahla yabathengi. Iguquguquka, yomelele, kwaye iyamelana nokufuma kunye neekhemikhali.

Isishwankathelo, iipolymers ze-thermoplastic ziklasi zezinto zeplastiki ezinokunyibilika kwaye ziphinde zibunjwe ngokuphindaphindiweyo ngaphandle kokwenza naluphi na utshintsho olubalulekileyo lweekhemikhali. Zisetyenziswa kakhulu kumashishini amaninzi ngenxa yokulula kwazo ukusetyenzwa, ukukwazi ukubunjwa zibe ziimo ezintsonkothileyo, kunye nokuphinda zisetyenziswe. Kukho iintlobo ezininzi ezahlukeneyo zeepolymers ze-thermoplastic, nganye ineempawu zayo kunye neempawu zayo.
