Polypropylene y'ubwoko butatu, cyangwa copolymer idakoraumuyoboro wa polypropylene, byitwa PPR mu magambo ahinnye. Iki gikoresho gikoresha ubushyuhe bwo gusudira, gifite ibikoresho byihariye byo gusudira no gukata, kandi gifite pulasitiki nyinshi. Igiciro nacyo kirahagije. Iyo hongeweho urwego rwo gukingira, imikorere y'ubushyuhe irarushaho kuba myiza kandi urukuta rw'imiyoboro, usibye aho insinga z'imbere n'inyuma zihurira, narwo ruragenda neza cyane.

Ubusanzwe ikoreshwa mu miyoboro yabanje gushyingurwa mu myobo miremire cyangwa mu nkuta zirimo.Umuyoboro wa PPRImara igihe kingana n'imyaka 50, ihendutse, ikora neza, irinda ubushyuhe kandi irinda ubushyuhe, irinda ingese, yoroshye kandi idakwirakwira ku rukuta rw'imbere, ifite umutekano kandi yizewe mu miyoboro y'amazi. Kugira ngo sisitemu ikomeze umutekano, hakenewe ibikoresho bigezweho n'abakozi babishoboye mu bwubatsi, bufite ikoranabuhanga rihanitse.

Amabara yoroshye kandi asa—aho kuba ay’amabara ahindagurika aboneka mu yindi miyoboro y’amazi—atangaUmuyoboro w'amazi wa PP-Ribara ryiza cyane. (Abaguzi bakunze gutekereza ko ibara ry'umweru ari ryo ryiza cyane ku miyoboro ya PP-R, ariko ibara si ryo rigena ubwiza; ubwiza bw'imiyoboro y'amazi ya PP-R butandukanye n'ubw'imiyoboro ya PP-R, kandi ibara ry'umuyoboro w'amazi ntaho rihuriye na ryo (hari n'andi mabara yongewemo hamwe na masterbatch y'amabara). Ibara iryo ari ryo ryose rishobora gukorwa igihe cyose masterbatch y'amabara ihari, kandi ntabwo izangiza cyangwa ngo igire ingaruka ku bwiza bwa PP. R rero, ntacyo bitwaye ibara ry'umuyoboro w'amazi.

Muri rusange, ibikoresho fatizo bya PP-R gusa ni byo bishobora gukoreshwa mu gukora ibicuruzwa byera. Urugero, mu gihe ibindi bicuruzwa by'amabara bitunganywa n'ibikoresho byakoreshejwe, imyanda, n'ibikoresho byo mu mfuruka, ibara ry'ibicuruzwa bivangwa no kongeramo ibikoresho byakoreshejwe, imyanda, n'ibikoresho byo mu mfuruka ntabwo ryoroshye kandi ringana. Ibara ry'ibicuruzwa ntirizahinduka bitewe n'ibikoresho byakoreshejwe, nibindi. Imbere n'inyuma by'ibicuruzwa bigomba kuba bidafite inenge kandi birambuye; inenge nk'uduheri tw'umwuka, uduce duto duto, imiyoboro, n'ibindi bihumanya ntibyemewe.

Ibikoresho by'ibanze byose byo gukoresha imiyoboro myiza y'amazi ya PP-R ni PP-R. (nta nyongeramusaruro). Igaragara neza, ifite ubuso bworoshye n'umukingo woroshye. Imiyoboro ya PP-R y'inyito yumva yoroshye. Muri rusange, uduce duto duto dukunda kubamo imyanda; polypropylene ni yo gice cy'ingenzi cy'imiyoboro ya PP-R. Imiyoboro mibi ihumura neza, mu gihe imiyoboro myiza yo ntabwo ihumura neza. Akenshi, polyethylene aho kuba polypropylene irahuzwa.

Ubushyuhe busanzwe bwo gusudira ku miyoboro ya PP-R buri hagati ya dogere selisiyusi 260 na 290. Ubwiza bw'ubushyuhe buzarushaho kugaragara neza kuri ubu bushyuhe. Igicuruzwa gishobora kwinjira mu mutwe w'icyuma cyo gusudira byoroshye mu gihe cyo gusudira niba ibipimo byo gusudira ari ibisanzwe. Byongeye kandi, utubuto two mu gice cy'igicuruzwa tuba dusa n'amazi, bigaragaza ko kitakozwe n'ibikoresho fatizo bya PP-R nyabyo.

Iki gicuruzwa kandi ntigikozwe mu bikoresho fatizo bya PP-R nyabyo niba utubuto two gukurura ubushyuhe dushobora gukonja no gukomera vuba (ubusanzwe mu masegonda 10). Ibi biterwa nuko PP-R ifite ubushobozi bwo kubika ubushyuhe cyane, bivuze ko umuvuduko wayo wo gukonja uzagenda buhoro mu buryo busanzwe.
Reba niba imiyoboro yashushanyijweho kandi niba umurambararo w'imbere w'umuyoboro waragoramye. Umurambararo w'imbere w'umuyoboro mwiza wa PP-R ntushobora gukururwa, kandi ntugondagurika byoroshye.
