Yini i-PP eyenziwe ngayo? Ukubheka okuningiliziwe kwezakhiwo kanye nezicelo zePolypropylene (PP)
Uma kukhulunywa ngezinto zokwenziwa zepulasitiki, umbuzo ojwayelekile yilokho okwenziwe yi-PP okwenziwe nge-plow Kulesi sihloko, sizokuhlaziya ngokuningiliziwe izakhiwo zamakhemikhali nezingokwenyama zezinto ze-PP kanye nezinhlobo zawo ezahlukahlukene zezicelo ezisezinkambu ezahlukene.
Yini i-PP?
I-PP (polypropylene) Igama lesiChinese ye-polypropylene, liyi-resin yokwenziwa ekhiqizwa yi-polymerication of propelene monomer. Kungokweqembu le-polyoleFem lamapulasitiki futhi kungenye yezimpawu ezisetshenziswa kakhulu emhlabeni. Izinto ze-polypropylene seziyinsika ebalulekile yomkhakha we-plastics ngenxa yokusebenza kwazo okuhle nezindleko eziphansi zokukhiqiza.
Ukwakheka kwamakhemikhali nezakhiwo ze-PP
Ngombono wamakhemikhali, isakhiwo samangqamuzana se-PP silula futhi siqukethe i-athomu ye-carbon ne-hydrogen i-atoms.pp inesakhiwo esihle samakhemikhali kanye nokuqina kwe-alkalo Okukwenzayo kusetshenziswe kabanzi kugesi nakwe-elekthronikhi okuqukethwe kunesithako esihle kakhulu sikagesi kanye nokutholwa komswakama okuphansi, okwenza kusetshenziswe kabanzi kumasimu kagesi nakwe-elekthronikhi.
Izakhiwo ezibonakalayo ze-PP
Izakhiwo ezibonakalayo ze-polypropylene zinquma ukusetshenziswa kwazo ezinhlotsheni eziningi ze-prestic.pp zinesilinganiso esiphakeme kakhulu, esinamandla ama-g / cm Amazinga okushisa aphezulu ngaphandle kokuba deformed.pp anendawo ephezulu yokuncibilika (160 kuye ku-170 ° C), okwenza ukuthi kwenzeke ukuyisebenzisa emazingeni okushisa aphezulu ngaphandle kokulimala. deformation. Lezi zakhiwo ezibonakalayo zenza i-PP ilungele ukufakwa, izimpahla zasendlini nezingxenye zezimoto.
Izindawo zohlelo lokusebenza lwe-PP izinto
Ngenxa yezakhiwo zayo ezinhle kakhulu, i-PP isetshenziswa ezinhlobonhlobo zezicelo. Embonini yokupakisha, i-PP isetshenziselwa kakhulu ukwenza izikhwama zepulasitiki, ukufakwa kokudla kanye namabhodlela amakhebhu ngoba akuyona ingozi, i-odorless futhi igcina ukudla kusha isikhathi eside. Emkhakheni wezokwelapha, i-PP isetshenziselwa ukwenza ama-syringes alahliweyo kanye ne-labware, ethandwa ngokumelana nayo kwamakhemikhali kanye nezimpahla zezimoto, lapho isetshenziselwa ukumelana nezinto zayo ezinhle kakhulu, ngenxa yezakhiwo ezingasindi.
Imvelo inobungane futhi iyasimeme
Ngokuqwashisa ngokwanda kokuvikelwa kwemvelo, impahla ye-PP ibaluleke kakhulu ukuthi imikhiqizo yayo yokuphinda isebenze kabusha.pp ingavuselelwa kabusha futhi iphinde isetshenziswe kabusha ngokuvuselelwa kabusha kwemishini ye-Cark.
Ukugcina
Umbuzo wokuthi i-PP eyenziwe ngayo ingaphendulwa ngokuqinile ngesakhiwo sayo samakhemikhali, impahla ebonakalayo, kanye nohlu olubanzi lwezicelo.PP ludlala indima enkulu ngenani elikhulayo lezimboni njengezinto eziqinile zezomnotho, ezihlala isikhathi emvelo. Uma udinga ukusebenza kwezindleko kanye nokuguquguquka lapho ukhetha izinto zepulasitiki, ngokungangabazeki i-PP ngokungangabazeki kuyindlela efanelekile.
