Chingwe chokhazikika-kuchokera ku ulusi kupita ku chingwe

Zopangira: polyamide, polypropylene ndi polyester.Chingwe chilichonse chimapangidwa ndi ulusi wowonda kwambiri.Zotsatirazi ndizofotokozera za ulusi waukulu womwe timagwiritsa ntchito komanso mawonekedwe ake.

Zogwiritsidwa ntchito pafupipafupi

Polyamide ndi fiber yomwe imagwiritsidwa ntchito kwambiri, yomwe imagwiritsidwa ntchito popanga zingwe zapamwamba kuchokera kuzinthu zopangidwa.Mitundu yodziwika bwino ya polyamide ndi DuPont nayiloni (PA 6.6) ndi Perlon(PA 6).Polyamide ndi yosavala, yamphamvu kwambiri komanso yotanuka kwambiri.Ikhoza kutenthedwa ndi mawonekedwe osatha-chinthuchi chimagwiritsidwa ntchito pokonza kutentha.Chifukwa chofuna kuyamwa mphamvu, chingwe champhamvu chimapangidwa ndi polyamide.Ulusi wa polyamide umagwiritsidwanso ntchito kwambiri popanga zingwe zosasunthika, ngakhale mtundu wazinthu wokhala ndi kufalikira pang'ono umasankhidwa.Kuipa kwa polyamide ndikuti imamwetsa madzi ochulukirapo, zomwe zimapangitsa kuti achepetse ngati anyowa.

Chifukwa ndi polypropylene, imakhala yopepuka kwambiri.

Polypropylene ndi yopepuka komanso yotsika mtengo.Chifukwa cha kuchepa kwake, polypropylene imagwiritsidwa ntchito kwambiri popanga zingwe zachitsulo, zomwe zimatetezedwa ndi ma polyamide sheaths.Polypropylene ndi yopepuka kwambiri kulemera kwake, yocheperako pang'onopang'ono ndipo imatha kuyandama.Ndicho chifukwa chake timachigwiritsa ntchito kupanga chingwe chathu chamtsinje.

Kugwiritsa ntchito polyester

Zingwe zosasunthika zopangidwa ndi ulusi wa poliyesitala zimagwiritsidwa ntchito makamaka pantchito zomwe zingakhudzidwe ndi ma asidi kapena mankhwala owononga.Mosiyana ndi polyamide, imakhala ndi asidi wambiri ndipo simamwa madzi.Komabe, ulusi wa poliyesitala uli ndi mphamvu zochepa zoyamwa mphamvu, zomwe zikutanthauza kuti kugwiritsidwa ntchito kwake ku PPE ndikochepa.

Kupeza mphamvu ya misozi yayikulu.

Dynema chingwe Dynema ndi chingwe chopangidwa ndi fiber chopangidwa ndi polyethylene yapamwamba kwambiri ya molekyulu.Ili ndi mphamvu zong'ambika kwambiri komanso kutalika kocheperako.Powerengedwa ndi chiŵerengero cha kulemera kwake, mphamvu yake yokhazikika ndi 15 nthawi ya chitsulo.Zinthu zake zazikulu ndizokana kuvala kwambiri, kukhazikika kwa ultraviolet komanso kulemera kopepuka.Komabe, chingwe cha Dyneema sichimapereka mphamvu zowonjezera mphamvu, zomwe zimapangitsa kuti zikhale zosayenera kwa zipangizo zodzitetezera.Chingwe cha Dyneema chimagwiritsidwa ntchito kwambiri kukoka zinthu zolemera.Nthawi zambiri amagwiritsidwa ntchito m'malo mwa zingwe zachitsulo zolemera.Pochita, malo osungunuka a chingwe cha Dyneema ndi otsika kwambiri.Izi zikutanthauza kuti ulusi wa Dynema chingwe Dynema (wokwera kwambiri molekyulu yolemera polyethylene chingwe) ukhoza kuonongeka pamene kutentha kumaposa 135 digiri Celsius.

Kutanthauzira kwangwiro kwa kudula kukaniza.

Aramid ndi chingwe champhamvu kwambiri komanso chosagwira kutentha komanso kukana kwambiri kudula.Mofanana ndi chingwe cha Dyneema, chingwe cha aramid sichipereka mphamvu zosunthika, choncho kugwiritsa ntchito PPE kumakhala kochepa.Chifukwa cha kukhudzika kwake kwambiri pakupindika ndi kutsika kwa ultraviolet kukana, ulusi wa aramid nthawi zambiri amapatsidwa ma polyamide sheath kuti aziwateteza.Timagwiritsa ntchito chingwe cha aramid kuchitapo kanthu pa chingwe cha dongosolo kuti tiyike ntchito, zomwe zimafuna kukulitsa pang'ono komanso kukana kwambiri kudula.
