I-PP yenziwe ngani? Ukubheka okuningiliziwe kwezakhiwo kanye nokusetshenziswa kwe-polypropylene (PP)
Uma kuziwa ezintweni zepulasitiki, umbuzo ojwayelekile ukuthi yini i-PP eyenziwe ngayo.PP, noma i-polypropylene, i-polymer ye-thermoplastic evame kakhulu kukho kokubili ukuphila kwansuku zonke kanye nokusebenza kwezimboni. Kulesi sihloko, sizohlaziya ngokuningiliziwe izakhiwo zamakhemikhali nezomzimba zezinto ze-PP kanye nobubanzi bayo bezinhlelo zokusebenza emikhakheni ehlukene.
Yini i-PP?
I-PP (I-Polypropylene) Igama lesiShayina le-polypropylene, iyinhlaka yokwenziwa ekhiqizwa i-polymerization ye-propylene monomer. Iyingxenye yeqembu le-polyolefin lamapulasitiki futhi ingenye yepulasitiki esetshenziswa kakhulu emhlabeni. Izinto ze-polypropylene seziphenduke insika ebalulekile embonini yepulasitiki ngenxa yokusebenza kwazo okuhle kakhulu kanye nezindleko zokukhiqiza eziphansi.
Isakhiwo samakhemikhali kanye nezakhiwo ze-PP
Ngokombono wamakhemikhali, ukwakheka kwamangqamuzana e-PP kulula futhi kuqukethe ama-athomu e-carbon ne-hydrogen. I-PP inesakhiwo esiqondile esinamayunithi amaningi e-propylene ochungechungeni lwamangqamuzana, futhi lesi sakhiwo sikunikeza ukumelana okuhle kwamakhemikhali nokuzinza.PP impahla ayiqukethe amabhondi aphindwe kabili, ngakho-ke ikhombisa ukumelana okuphezulu kwe-oxidation, i-asidi ne-alkali izindawo. impahla ine-insulation kagesi enhle kakhulu kanye nokumunca umswakama ophansi, okwenza isetshenziswe kabanzi emikhakheni kagesi neye-elekthronikhi.
Izakhiwo Zomzimba ze-PP
Izakhiwo ezibonakalayo ze-polypropylene zinquma ukusetshenziswa kwayo kuhlelo olubanzi lwezinhlelo zokusebenza.PP inezinga eliphezulu lokucwebezela, okuyenza iqine kakhulu futhi iqine.PP inobukhulu obuphansi (cishe u-0.90 kuya ku-0.91 g/cm³), okungenye ephansi kakhulu phakathi kwamapulasitiki, okwenza imikhiqizo ye-PP ibe nesisindo esincane. amazinga okushisa ngaphandle kokukhubazeka.PP inezinga eliphezulu lokuncibilika (160 kuya ku-170°C), okwenza kube nokwenzeka ukulisebenzisa emazingeni okushisa aphezulu ngaphandle kokukhubazeka. ukuguquguquka. Lezi zakhiwo ezibonakalayo zenza i-PP ilungele ukupakishwa, izimpahla zasendlini kanye nezingxenye zezimoto.
Izindawo zokufaka izicelo ze-PP materials
Ngenxa yezakhiwo zayo ezinhle kakhulu, i-PP isetshenziswa ezinhlobonhlobo zezinhlelo zokusebenza. Embonini yokupakisha, i-PP ijwayele ukusetshenziselwa ukwenza izikhwama zepulasitiki, ukupakisha ukudla kanye nezigqoko zamabhodlela ngoba ayinabo ubuthi, ayinaphunga futhi igcina ukudla kusha isikhathi eside. Emkhakheni wezokwelapha, i-PP isetshenziselwa ukwenza amasirinji alahlwayo kanye ne-labware, ethandwa ngenxa yokumelana namakhemikhali awo kanye nezindawo ezinhle zokuvala inzalo, nasembonini yezimoto, lapho isetshenziselwa khona ukwenza izinsimbi zangaphakathi namabhampa, phakathi kwezinye izinto, ngenxa yokumelana nomthelela omuhle kakhulu kanye nezakhiwo ezingasindi.
Inobungane Emvelweni futhi Iyasimema
Ngokuqwashisa okwandayo kokuvikelwa kwemvelo, impahla ye-PP ihlonishwa ngenxa yokusebenziseka kwayo kabusha.Imikhiqizo ye-PP ingacutshungulwa futhi iphinde isetshenziswe ngomshini wokugaywa kabusha noma ukugaywa kabusha kwamakhemikhali, kwehliswe umthwalo endaweni ezungezile.Ukukhishwa kwekhabhoni ephansi yePP kanye nezakhiwo eziwohlokayo nakho kuyenza ibe ikhandidethi eliqinile lezinto ezisetshenziswayo ezilungele imvelo zesikhathi esizayo.
Isiphetho
Umbuzo wokuthi i-PP yenziwe ngani ungaphendulwa ngokuphelele ngesakhiwo sayo samakhemikhali, izici ezibonakalayo, kanye nohlu olubanzi lwezinhlelo zokusebenza.I-PP idlala indima ebalulekile enanini elikhulayo lezimboni njengento eyongayo, ehlala isikhathi eside, futhi ehambisana nemvelo. Uma udinga ukusebenza kahle kwezindleko kanye nokuguquguquka lapho ukhetha impahla yepulasitiki, i-PP ngokungangabazeki iyisinqumo esihle.
