Insinga za polypropylene zifite akamaro kabiri mu gukoresha sima:
1) Kurinda ko plastiki igabanuka mu byuma bya sima.
Mu gihe cyo gushyiraho no gukomera kwa sima, amazi yo hejuru ashobora gutuma plastiki igabanuka ndetse ikanacika. Kongeramo imigozi ya polypropylene kuri sima bishobora gukumira iyo migozi. Bitewe n'uburyo bworoshye bwo gukaraba bw'imigozi ya polypropylene ugereranije na sima ikomeye, kwiyongera k'ubudahangarwa bw'imigozi (gucikagurika guterwa n'ubushyuhe cyangwa umutwaro wa mekanike) bya sima ikomeye ni bike, kandi kwiyongera k'imbaraga zo gukurura no gucikagurika ntabwo ari ikintu gikomeye, ibyo bikaba bifite urwego runaka rwo kunoza ubukomere bwa sima.
2) Kongera ubushobozi bwo kurwanya ubushyuhe bwa sima ikomeye. Iyo ubushyuhe bwinshi bukoreshejwe, imigozi ya polypropylene ibanza koroha ikazima, bigatuma habaho imyenge myinshi muri sima. Amazi ahumeka bitewe n'ubushyuhe bwinshi muri sima ashobora gusohoka muri iyo myenge, bikarinda ko habaho umuvuduko mwinshi w'imbere bitewe n'ubushyuhe bw'amazi kandi bigatuma sima iturika, bityo bikanongera cyane igihe cyo kurwanya ubushyuhe n'urwego rwa sima.
Imigozi ya polypropylene ishobora kugabanywamo imigozi miremire, imigozi migufi, imyenda idafunze ya spunbond, imyenda idafunze yashongeshejwe, nibindi.
(1) Yoroheje
Ubucucike bwa fibre ya polypropylene ni 0.90-0.92 g/cm, ikaba ari yo yoroheje cyane mu migozi yose ya shimi, 20% yoroheje kurusha nayiloni, 30% yoroheje kurusha polyester, na 40% yoroheje kurusha imigozi ya viscose. Kubwibyo, irakwiriye cyane gukoreshwa nk'inyunganiramirire ku myenda y'imbeho cyangwa nk'imyenda yo kurira ku rubura, kuzamuka imisozi, n'indi myenda.
(2) Ingufu nyinshi, uburimbane bwiza, ubushobozi bwo kwangirika, no kudashwanyagurika
Polypropylene ifite imbaraga nyinshi (nk'uko bimeze mu bihe byumye n'ibitose) kandi ni ibikoresho byiza byo gukora imiyoboro y'uburobyi n'insinga; Irwanya kwangirika no gukomera, ifite imbaraga nk'iza polyester na nylon, ifite umuvuduko wo gusubira inyuma ugereranywa na nylon n'ubwoya, iri hejuru cyane y'imiyoboro ya polyester na viscose; Polypropylene ifite ubushobozi buke bwo kudahinduka, ikunda gushonga no kwangirika, irwanya udukoko, kandi ntigira ingaruka mbi; Irwanya imiti ikoreshwa mu burozi iruta imiyoboro rusange.
(3) Ifite ubushobozi bwo gukingira amashanyarazi no kubika ubushyuhe
Fibre ya polypropylene ifite ubushobozi bwo guhangana n’amashanyarazi bwinshi (7 × 10 Ω. cm) kandi ifite ubushobozi bwo gutwara ubushyuhe buke. Ugereranyije n’izindi fibre za shimi, fibre ya polypropylene ifite ubushobozi bwo gukingira amashanyarazi no kubika ubushyuhe neza, ariko ikunda gukora amashanyarazi adahindagurika mu gihe cyo kuyatunganya.
(4) Ubushobozi buke bwo kurwanya ubushyuhe n'ubusaza
Imigozi ya polypropylene ifite aho ishongesha hato (165-173 ℃) kandi ntishobora gushonga neza mu rumuri n'ubushyuhe. Kubwibyo, imigozi ya polypropylene ifite ubushobozi buke bwo kudashyuha, kudashaza, kandi ntishobora gusigwa ipasi. Ariko, ubushobozi bwo kudashaza bushobora kunozwa wongeyeho ikintu kirwanya gusaza mu gihe cyo kuzunguruka.
(5) Ubushuhe buke butuma umuntu ahora ahumetse kandi ntagire ibara ryiza
Uburyo bwo kwinjiza ubushuhe n'irangi ry'imigozi ya polypropylene ni bwo bubi cyane mu migozi ya shimi, aho hafi nta bushuhe bufata kandi ubushuhe bugasubirana bungana na 0.03%. Polypropylene nziza cyane ifata neza ifite ubushobozi bwo gukurura amazi, kandi umwuka w'amazi ushobora gukurwa mu miyoboro y'amazi iri mu migozi. Nyuma yo gukorwamo imyenda, ihumure ry'imyenda riba ryiza kurushaho, cyane cyane iyo imigozi ya polypropylene ikoze neza cyane. Bitewe n'ubwiyongere bw'ubuso, ibyuya bishobora koherezwa vuba, bigatuma uruhu rumererwa neza. Bitewe n'uko imigozi idafata ubushuhe kandi ikaba nke, imyenda ya polypropylene ifite imiterere yo koroshya kumesa no kuma vuba.
Polypropylene ifite ubushobozi buke bwo gusiga irangi, amabara yoroheje, kandi ntiyihuse cyane mu gusiga irangi. Ibikoresho bisanzwe ntibishobora kuyisiga irangi, kandi insinga nyinshi za polypropylene zifite amabara menshi zikorwa hakoreshejwe irangi ribanza guhindurwa. Irangi ry'ibikoresho fatizo n'impinduka za fibre birashobora gukoreshwa, kandi ibintu bigabanya ingano y'ibikomoka kuri lisansi bishobora kuvangwa mbere yo gushonga.
