PP ikozwe niki? Reba birambuye kumiterere nibisabwa bya polypropilene (PP)
Iyo bigeze ku bikoresho bya pulasitike, ikibazo rusange nicyo PP ikozwe.PP, cyangwa polypropilene, ni polymer ya termoplastique yiganje cyane mubuzima bwa buri munsi ndetse no mubikorwa byinganda. Muri iyi ngingo, tuzasesengura mu buryo burambuye imiti n’imiterere yibikoresho bya PP hamwe nuburyo bugari bukoreshwa mubice bitandukanye.
PP ni iki?
PP (Polypropilene) Izina ryigishinwa kuri polypropilene, ni resinike ya sintetike ikorwa na polymerisation ya propylene monomer. Ni iyitsinda rya polyolefin ya plastike kandi ni imwe muri plastiki zikoreshwa cyane kwisi. Ibikoresho bya polypropilene byabaye inkingi yingenzi yinganda za plastiki kubera imikorere myiza yazo nigiciro gito cyumusaruro.
Imiterere yimiti nimiterere ya PP
Dufatiye ku miti, imiterere ya molekuline ya PP iroroshye kandi igizwe na atome ya karubone na hydrogène.PP ifite imiterere yumurongo ufite ibice byinshi bya propylene mumurongo wa molekile, kandi iyi miterere itanga imiti irwanya imiti kandi ihamye. ikoreshwa cyane mumashanyarazi na elegitoroniki.
Ibintu bifatika bya PP
Imiterere yumubiri wa polypropilene igena imikoreshereze yayo muburyo butandukanye.PP ifite urwego rwo hejuru rwa kristu, ituma rukomera kandi rukomeye.PP ifite ubucucike buke (hafi 0,90 kugeza 0,91 g / cm³), ikaba ari imwe murwego rwo hasi muri plastiki, bigatuma ibicuruzwa bya PP byoroha cyane. 170 ° C), ituma bishoboka kuyikoresha mubushyuhe bwo hejuru utarinze guhinduka. Guhindura. Iyi miterere yumubiri ituma PP iba ​​nziza mugupakira, ibicuruzwa byo murugo nibice byimodoka.
Ahantu ho gusaba ibikoresho bya PP
Bitewe nibyiza byayo, PP ikoreshwa muburyo butandukanye bwa porogaramu. Mu nganda zipakira, PP isanzwe ikoreshwa mugukora imifuka ya pulasitike, gupakira ibiryo hamwe nudupapuro twa icupa kuko ntabwo ari uburozi, impumuro nziza kandi ituma ibiryo bishya mugihe kirekire. Mu rwego rw’ubuvuzi, PP ikoreshwa mu gukora siringi ikoreshwa hamwe na laboratoire, itoneshwa n’imiti irwanya imiti ndetse n’imiterere myiza ya sterisizasiya, ndetse no mu nganda z’imodoka, aho ikoreshwa mu gukora imitambiko yimbere na bamperi, hamwe n’ibindi, kubera ingaruka zayo nziza zo guhangana n’imiterere yoroheje.
Ibidukikije byangiza ibidukikije kandi birambye
Hamwe no kurushaho gukangurira kurengera ibidukikije, ibikoresho bya PP bihabwa agaciro kubwo kongera gukoreshwa.Ibicuruzwa bya PP birashobora gusubirwamo kandi bigakoreshwa hifashishijwe uburyo bwo gutunganya imashini cyangwa gutunganya imiti, kugabanya umutwaro ku bidukikije.
Umwanzuro
Ikibazo cyibyo PP ikozwe gishobora gusubizwa byimazeyo binyuze mumiterere yimiti, imiterere yumubiri, hamwe nibikorwa byinshi.PP igira uruhare runini mubikorwa byiyongera byinganda nkibikoresho byubukungu, biramba, kandi bitangiza ibidukikije. Niba ukeneye ikiguzi-cyiza kandi gihindagurika mugihe uhisemo ibikoresho bya plastiki, PP ntagushidikanya guhitamo neza.
