Kodi polypropylene ndi chiyani? -Katundu, Ntchito ndi Ubwino wa Polypropylene
Kodi Polypropylene (PP) ndi chiyani? Polypropylene ndi polima wa thermoplastic wopangidwa kuchokera ku polymerization ya propylene monomers ndipo ndi imodzi mwazinthu zamapulasitiki zomwe zimagwiritsidwa ntchito kwambiri padziko lonse lapansi. Chifukwa cha mawonekedwe ake apadera amankhwala ndi thupi, polypropylene imakhala ndi malo ofunikira pamafakitale, azachipatala, m'nyumba ndi m'mafakitale a chakudya. M'nkhaniyi, tiwona mozama za zinthu zofunika za polypropylene, ntchito zake zazikulu ndi ubwino wake.
Basic katundu wa polypropylene
Kodi polypropylene ndi chiyani? Pankhani ya kapangidwe ka mankhwala, polypropylene ndi polima wopangidwa ndi kuwonjezera ma polymerization a propylene monomers. Mapangidwe ake a maselo ndi ofanana kwambiri ndipo nthawi zambiri amakhala mu mawonekedwe a semi-crystalline. Kapangidwe ka symmetry ndi crystalline kameneka kamapatsa polypropylene zinthu zingapo zabwino kwambiri zakuthupi, monga malo osungunuka kwambiri, osalimba komanso kukhazikika kwamankhwala. Posungunuka wa polypropylene nthawi zambiri amakhala pakati pa 130 ° C ndi 171 ° C, zomwe zimapangitsa kuti ikhalebe yokhazikika pa kutentha kwambiri. Ndi kachulukidwe pafupifupi 0.9 g/cm³, polypropylene ndi yopepuka kuposa mapulasitiki ena ambiri wamba monga polyethylene ndipo ali ndi kukana kwa dzimbiri.
Ntchito zazikulu za polypropylene
Kodi polypropylene ndi chiyani? Kodi ntchito zake ndi ziti m'mafakitale osiyanasiyana? Chifukwa cha zinthu zake zosiyanasiyana, polypropylene imagwiritsidwa ntchito pazinthu zosiyanasiyana. M'makampani onyamula katundu, polypropylene imagwiritsidwa ntchito mochulukira pazinthu monga kunyamula chakudya, zipewa ndi mafilimu. Kukaniza kwake kwamankhwala komanso kukana chinyezi kumapangitsa kukhala koyenera kulongedza chakudya, kuonetsetsa chitetezo chazakudya komanso nthawi yashelufu. M'gawo la zipangizo zapakhomo, polypropylene imagwiritsidwa ntchito popanga mipando, zotengera ndi nsalu, mwa zina, chifukwa cha kulemera kwake komanso kulimba kwake, komanso kumasuka kwake kuyeretsa ndi kukonza. Kupitilira apo, m'makampani azachipatala, polypropylene imagwiritsidwa ntchito kupanga ma syringe, machubu oyesera ndi zida zina zachipatala zotayidwa chifukwa cha kuyanjana kwake ndi antimicrobial.
Ubwino wa Polypropylene ndi Zamtsogolo Zamtsogolo
Pankhani ya polypropylene, phindu lake lodziwika bwino limaphatikizapo kutentha ndi kukana kwa mankhwala, komanso ndalama zochepa zopangira. Polypropylene yosungunuka kwambiri imalola kuti igwiritsidwe ntchito pamatenthedwe apamwamba popanda vuto la kupotoza kapena kusungunuka. Kukaniza kwake kwamankhwala kumapangitsa kuti polypropylene ikhalebe yokhazikika komanso yosawonongeka ikakumana ndi ma acid, alkalis ndi zosungunulira za organic. Njira yopangira polypropylene yosavuta komanso yotsika mtengo yapangitsa kuti igwiritsidwe ntchito kwambiri pazinthu zosiyanasiyana pamoyo watsiku ndi tsiku.
Pamene chidziwitso cha chilengedwe chikukula, kubwezeretsedwa kwa polypropylene kwakhala mwayi waukulu. Ukadaulo wamakono umalola kubwezeredwa kwa zinthu zotayidwa za polypropylene, zomwe zimachepetsa kwambiri kuwononga zinthu komanso kuwononga chilengedwe. Chifukwa chake, chitukuko chamtsogolo cha zida za polypropylene chidzapereka chidwi kwambiri pachitetezo cha chilengedwe ndi kukhazikika, ndikupititsa patsogolo magwiridwe antchito ake ndi kuchuluka kwake kogwiritsa ntchito kudzera muukadaulo waukadaulo.
Mapeto
Kodi polypropylene material ndi chiyani? Kusanthula mwatsatanetsatane mu pepalali kukuwonetsa kuti polypropylene ndi polima ya thermoplastic yokhala ndi ntchito zambiri komanso zinthu zambiri zabwino kwambiri. Malo ake osungunuka kwambiri, kukana kwa mankhwala, kulemera kwake, ndi mtengo wotsika kumapangitsa kukhala kofunikira m'mafakitale ambiri. Ndi chitukuko cha matekinoloje ochezeka ndi chilengedwe, polypropylene ili wokonzeka kugwiritsidwa ntchito mtsogolomo. Ngati mukuyang'ana zida zapulasitiki zogwira ntchito kwambiri komanso zotsika mtengo, polypropylene ndiye njira yoyenera kuiganizira.
