Yini i-polypropylene? -Ipropeties, izinhlelo zokusebenza nezinzuzo ze-polypropylene
Yini i-polypropylene (PP)? I-Polypropylene iyi-polymer ye-thermoplastic eyenziwe nge-polymerication of propelene monomers futhi ingenye yezinto zokwakha zepulasitiki ezisetshenziswa kakhulu emhlabeni. Ngenxa yezakhiwo zayo ezihlukile zamakhemikhali nezingokomzimba, i-polypropylene ithatha izicelo ezibalulekile ezisetshenzisweni zezimboni, ezokwelashwa, zasendlini nasekudla. Kulesi sihloko, sibheka ukujula kwezakhiwo eziyisisekelo ze-polypropylene, izinhlelo zayo eziphambili nezinzuzo zalo.
Izici eziyisisekelo zePolypropylene
Yini i-polypropylene? Ngokwesakhiwo samakhemikhali, i-polypropylene yi-polymer eyakhiwa yi-polymerication yesengezo ye-propelene monomers. Isakhiwo saso samangqamuzana sinama-symmetric kakhulu futhi sivame ukuba khona ngendlela ye-semi-crystalline. Lesi sakhiwo se-symmetry ne-crystalline sinikeza i-polypropylene inani lezakhiwo ezinhle kakhulu zenyama, njengephuzu eliphakeme elincibilikayo, ukuqina okuphansi kanye nokuqina okuhle kwamakhemikhali. Iphoyinti likancibilika likaPolypropylene livame phakathi kuka-130 ° C no-171 ° C, okuvumela ukuthi lihlale lizinze ngokukhulumela amazinga okushisa aphezulu. Ngokuqina kwe-0.9 g / cm³, i-polypropylene ilula kunezinye iziprisidi eziningi ezivamile njenge-polyethylene futhi inokuphikiswa okuhle kakhulu kokugqwala.
Izicelo ezibalulekile ze-polypropylene
Yini i-polypropylene? Yini izinhlelo zayo ezimbonini ezahlukahlukene? Ngenxa yezakhiwo zayo ezahlukahlukene, i-polypropylene isetshenziswa ezinhlobonhlobo zezicelo. Embonini yokupakisha, i-polypropylene isetshenziswa ngamanani amakhulu emikhiqizo efana nokupakishwa kokudla, ama-cap namafilimu. Ukumelana kwayo kwamakhemikhali nokumelana kwawo komswakama kwenza kube kuhle ukufakwa kokudla, ukuqinisekisa ukuphepha kokudla kanye nempilo eshalofly. Emkhakheni weFoyFings yasekhaya, i-polypropylene isetshenziselwa ukwenza ifenisha, iziqukathi nezindwangu, phakathi kwezinye izinto, ngenxa yesisindo sayo sokukhanya nokuqina kwayo, kanye nokuhlanzeka kwayo. Ngaphezu kwalokho, embonini yezokunakekelwa kwempilo, i-polypropylene isetshenziselwa ukukhiqiza ama-syringes, amashubhu wokuhlola namanye amadivaysi ezokwelapha alahlekile ngenxa yokuthambekela kwawo okuhle kanye nezakhiwo ze-antimicrobial.
Izinzuzo ze-polypropylene kanye nentuthuko yesikhathi esizayo
Uma kukhulunywa nge-polypropylene, izinzuzo zayo ezivelele kunazo zonke zifaka ukumelana nokushisa namakhemikhali, kanye nezindleko zokukhiqiza eziphansi. Iphoyinti eliphakeme lePolypropylene Liyayivumela ukuthi isetshenziswe emazingeni okushisa aphezulu ngaphandle kwezinkinga zokuhlanekezela noma ukuncibilika. Ukumelana kwayo okuhle kwamakhemikhali kuvumela i-polypropylene ukuze ihlale iqinile futhi hhayi i-corlode lapho ivezwa ama-acid, ama-alkali kanye ne-organic solvents. Inqubo yokukhiqiza ye-polypropylene elula futhi ephansi futhi iholele ekusetshenzisweni kwayo okubanzi emikhiqizweni ehlukahlukene empilweni yansuku zonke.
Njengoba ukuqwashisa ngezemvelo kukhula, ukufakwa kabusha kwe-polypropylene's kube yinzuzo enkulu. Ubuchwepheshe besimanje buvumela ukuphindwa kabusha kwezinto zokwakha imfucuza, okunciphisa kakhulu imfucuza yezinsizakusebenza nokungcoliswa kwemvelo. Ngakho-ke, ukuthuthukiswa kwesikhathi esizayo kwe-polypropylene izinto kuzokunaka kakhulu ukuvikelwa kwemvelo nokusimama, futhi kuphinde kuthuthukise ukusebenza kwayo kanye nokubuyiselwa kwayo kohlelo lokusebenza ngobuchwepheshe obusha.
Ukugcina
Yiziphi izinto ze-polypropylene? Ukuhlaziywa okuningiliziwe kuleli phepha kukhombisa ukuthi i-polypropylene iyi-polymer ye-thermoplastic enezinhlobonhlobo zezicelo nezakhiwo eziningi ezinhle kakhulu. Iphoyinti layo eliphakeme eliphakeme, ukumelana kwamakhemikhali, isisindo esikhanyayo, nezindleko eziphansi kwenza kubaluleke kwizimboni eziningi. Ngokuthuthukiswa kobuchwepheshe obunobuhlakani bemvelo, i-polypropylene ilungele izinhlelo zokusebenza ezithembisa ngokwengeziwe ngokuzayo. Uma ufuna ukusebenza kweplastiki okuphezulu futhi okungabizi, i-polypropylene ngokuqinisekile inketho okufanele icatshangelwe.
