Chii chinonzi polypropylene? -Properties, zvikumbiro uye zvakanaka zve polypropylene
Chii chinonzi polypropylene (pp)? Polypropylene is a thermplastic polymer yakagadzirwa kubva phermerisation yeProlleniti Menomers uye ndeimwe yemidziyo yepurasitiki zvakanyanya pasi. Nekuda kweiyo yakasarudzika yemakemikari uye yemuviri zvivakwa, polypropylene inogara chinzvimbo chakakosha mumagariro, zvekurapa, imba uye zvekudya zvekudya zvekudya. Munyaya ino, isu tinotarisa zvakadzama zvinhu zvakakosha zvePolypropylene, mainini mainonyorera uye zvakanaka zvawo.
Basic Pfuma yePolypropylene
Chii chinonzi polypropylene? Panyaya yemakemikari chimiro, polypropylene iPolymer yakaumbwa nekuwedzera Polymerisation yeProlleny Monomers. Yayo moleky chimiro inoenderana zvakanyanya uye kazhinji inowanikwa mune imwe hafu-crystalline fomu. Iyi symmetry uye crystalline chimiro chinopa polypropylene nhamba yakanakisa yemuviri, senge nzvimbo yakanyanya yekunyungudika, yakaderera mhepo uye yakaderera makemikari kugadzikana kwemakemikari. Pollypropyley inonyunguduka inonyungudika kazhinji pakati pe150 ° C na181 ° C, inobvumira kuti irambe iri morphologically yakagadzikana pakupisa kwakanyanya. Nekuwedzera kweanenge 0.9 g / cm³, cm³, polypropylene yakareruka kupfuura mamwe maPlassics mazhinji akadai saPolyethyle uye ane zvakanakisa kurwisa.
Key application yePolypropylene
Chii chinonzi polypropylene? Ndezvipi zvinoshandiswa zvaro mumaindasitiri akasiyana? Nekuda kwezvinhu zvaro zvakasiyana siyana, polypropylene inoshandiswa mune dzakasiyana siyana dzekushandisa. Mune indasitiri yokutakura, polypropylene inoshandiswa mune yakakura huwandu hwezvigadzirwa zvakadai sekudya kwekudya, macaps uye mafirimu. Kupesana kwayo kwemakemikari uye kurwisa kunyengedza kunoita kuti ive yakakodzera pakudya kwekudya, ichivimbisa kuchengetedzwa kwekudya uye hupenyu hwesherufu. Mumba mamiririri emidziyo, polypropyle inoshandiswa kugadzira fenicha, midziyo uye manyoro, pakati pezvimwe zvinhu, nekuda kwehuremu hwayo uye kusimba kwayo kwekuchenesa nekugadzirisa. Kupfuurirazve, muindasitiri yehutano, polypropylene inoshandiswa kuburitsa syringes, tubes tubes uye zvimwe zvinoshandiswa zvekurapa nekuda kwezvinhu zvakanaka zvehukadzi uye antimicrobial zvivakwa.
Polypropylene inobatsira uye zviitiko zvenguva yemberi
Kana zvasvika kune izvo polypropylene iri, zvakanakira zvakanakira zvinosanganisira kupisa uye makemikari kuramba, pamwe nemitengo yakaderera yekugadzira. Pollypropylene yakakwira yekunyungudika point inobvumira kuti ishandiswe pakudziya kwakanyanya pasina matambudziko ekukanganisa kana kunyungudika. Kwayo yakanaka yemakemikari kurwisa inobvumira polypropylene kuramba yakagadzikana uye kwete corrode kana yakavezwa kuAkiids, alkalis uye organic sol sol. Pollypropylene's isiriyo uye yakaderera-mutengo-mutengo wekugadzira zvakakonzera kushandiswa kwayo kwakapararira mune dzakasiyana siyana zvigadzirwa muhupenyu hwezuva nezuva hupenyu.
Sezvo kuziva kwezvakatipoteredza kunokura, kurongeka kwemuchato kwave kuita kwakakosha mukana. Tekinoroji yemazuva ano inobvumidza kudzokororwa kwetambisa pombi polypropylene zvigadzirwa, izvo zvinoderedza zvakanyanya kutambisa zviwanikwa uye kusvibiswa kwezvakatipoteredza. Naizvozvo, kusimudzira ramangwana kwezvinhu zvePolypropylene kuchaisa zvakanyanya kuchengetedzwa kwezvakatipoteredza uye nekuchengetedza, uye kuwedzera kusimudzira maitiro ayo uye chiitiko chekushandisa kuburikidza nehunyanzvi hwekugadzira tekinoroji.
Mhedziso
Chii chinonzi polypropylene zvinyorwa? Kuongororwa kwakadzama mune ino pepa kunoratidza kuti polypropylene in the thermoplastic polymer ine huwandu hwakawanda hwekushandisa uye zvakawanda zvakanaka zvivakwa. Pfungwa dzaro dzakareba dzekunyungudika, kurwisa kwemakemikari, kurema kwechiedza, uye mutengo wakaderera unoita kuti zviite zvakakosha mumaindasitiri akawanda. Nekuvandudzwa kwematongerwo enyika ane hushamwari, polypropylene anogadzirira kunyange zvakanyanya kuvimbisa zvinoshandiswa mune ramangwana. Kana iwe uchitsvaga yakakwira-plast-plast-yepurasitiki zvinhu, polypropylene zvirokwazvo isarudzo yakakodzera kufunga nezvayo.
