Tuzi ko tuzatera imbere gusa iyo dushobora kwemeza ko duhangana ku giciro kimwe kandi ko dufite ireme ryiza kandi bikaba byiza icyarimwe kuriValve yo guhagarika mu Bushinwa, Ibikoresho by'imiyoboro, Isosiyete yacu imaze imyaka irenga icumi ikora ibi, imaze kugira izina ryiza mu gihugu no mu mahanga. Bityo twakira inshuti ziturutse impande zose z'isi ngo zize kuduhamagara, atari mu bucuruzi gusa, ahubwo no mu bucuti.

Imiyoboro ya PPR

Ugereranyije n'imiyoboro y'icyuma, imiyoboro ya PPR ifite ibyiza byo koroshya kuyishyiraho, kuyirinda ubushyuhe, no kurwanya ingese. Ni ibikoresho by'amazi byiza kandi bitanga amazi meza kandi ni byo bicuruzwa by'amazi bikunze kuboneka ku isoko. Imiyoboro ya PPR iboneka cyane cyane mu mabara akurikira, umweru, ibara ry'ikijuju, icyatsi kibisi n'amabara ya curry, impamvu iri tandukaniro riterwa ahanini n'amabara atandukanye yongewemo.

Uretse imiterere y'imiyoboro ya pulasitiki muri rusange nko kuba ifite uburemere bworoshye, idatwarwa n'ingese, idahindagurika, ndetse no kumara igihe kirekire, imiyoboro ya PP-R ifite imiterere y'ingenzi ikurikira:

1 Ntibihumanya kandi ntibigira isuku.
Molekile z’ibikoresho fatizo bya PP-R ni ibintu bya karuboni na hydrogen gusa, kandi nta bintu byangiza cyangwa byangiza bihari. Ni isuku kandi yizewe. Ntabwo ikoreshwa gusa ku miyoboro y’amazi akonje n’ashyushye, ahubwo inakoreshwa no mu miyoboro y’amazi meza yo kunywa.

2 Kubungabunga ubushyuhe no kuzigama ingufu.
Ubushyuhe bw'umuyoboro wa PP-R ni 0.21w/mk, ni ukuvuga 1/200 gusa cy'umuyoboro w'icyuma.

3 Ubudahangarwa bw'ubushyuhe bwiza.
Aho Vicat yorohereza umuyoboro wa PP-R ni 131.5°C. Ubushyuhe ntarengwa bwo gukora bushobora kugera kuri 95°C, bushobora kuzuza ibisabwa n'amazi ashyushye mu mategeko agenga imiyoboro y'amazi n'imiyoboro y'amazi mu nyubako.

4 Igihe kirekire cyo gukora.
Mu gihe ubushyuhe bw'imikorere bwa dogere 70°C n'umuvuduko w'imikorere (PN) wa 1.0MPa, igihe cyo gukora cy'umuyoboro wa PP-R gishobora kugera ku myaka irenga 50 (mu gihe ibikoresho by'umuyoboro bigomba kuba S3.2 na S2.5 cyangwa birenga); mu gihe cy'ubushyuhe busanzwe (20°C) igihe cyo gukora gishobora kugera ku myaka irenga 100.

5 Gushyiramo byoroshye kandi byizewe.
PP-R ifite ubushobozi bwo gusudira neza. Imiyoboro n'ibikoresho bishobora guhuzwa hakoreshejwe amashanyarazi ashyushye. Gushyiraho biroroshye kandi ingingo zizewe. Ingufu z'ingingo ziruta imbaraga z'umuyoboro ubwawo.

Ibikoresho 6 bishobora kongera gukoreshwa.
Imyanda ya PP-R isukurwa, igashwanyagurika, ikongera gukoreshwa mu gukora imiyoboro n'ibikoresho. Ingano y'ibikoresho byasubiwemo ntirenga 10% by'ingano yose kandi ntigira ingaruka ku bwiza bw'ibicuruzwa.

gushyiraho

Tuzi ko tuzatera imbere gusa iyo dushobora kwemeza ko duhangana ku giciro cyacu hamwe kandi ko dufite ubwiza bwiza, icyarimwe kandi tukabona ibiciro bihendutse ku rutonde rw'ibikenewe mu Bushinwa, igishushanyo mbonera gishya cya PPR, icyuma gihagarika amazi gifunga icyuma ...
Urutonde rw'ibiciro bihendutse rwa Valve yo guhagarika mu Bushinwa, Ibikoresho by'imiyoboro, Mu gihe cy'imyaka irenga icumi dufite uburambe muri iki gikorwa, ikigo cyacu cyamenyekanye cyane mu gihugu no mu mahanga. Bityo twakira inshuti ziturutse impande zose z'isi ngo zize kuduhamagara, atari ku bw'ubucuruzi gusa, ahubwo no ku bw'ubucuti.
