100g-600g yopumira yopumira ya polypropylene yaifupi fiber singano kukhomeredwa sanali nsalu geotextile

Pankhani yopanga nsalu zopanda nsalu, poliyesitala (PET) ndi polypropylene (PP) akadali zida zazikulu zopangira, zomwe zimawerengera zoposa 95% yazinthu zonse zopangira ulusi zomwe zimagwiritsidwa ntchito munsalu zosalukidwa. Geotextile yopangidwa ndi ulusi wa polypropylene kudzera mu kubaya singano ndi polypropylene geotextile, yomwe imadziwikanso kuti polypropylene geotextile kapena polypropylene nsalu. Polypropylene yochepa CHIKWANGWANI singano kukhomerera nonwoven geotextiles anawagawa mu mitundu iwiri: polypropylene lalifupi CHIKWANGWANI geotextiles ndi polypropylene yaitali CHIKWANGWANI geotextiles.

Makhalidwe a polypropylene short fiber singano kukhomeredwa nonwoven geotextile monga:

(1) Mphamvu zabwino. Mphamvuyi ndi yotsika pang'ono kwa PET, koma yamphamvu kuposa ulusi wamba, yokhala ndi kutalika kwa 35% mpaka 60%; Mphamvu yamphamvu imafunika, ndi kuphulika kwa 35% mpaka 60%;

(2) Kutanuka bwino. Kuchira kwake nthawi yomweyo kumakhala bwino kuposa PET fiber, koma ndi koipa kuposa PET fiber pansi pa kupsinjika kwa nthawi yaitali; Koma pansi pa zovuta za nthawi yaitali, zimakhala zoipa kuposa PET fibers;

(3) Kusagwira bwino kutentha. Malo ake ochepetsetsa ali pakati pa 130 ℃ ndi 160 ℃, ndipo malo ake osungunuka ali pakati pa 165 ℃ ndi 173 ℃. Kutsika kwake kwa kutentha kumayambira 165 ℃ mpaka 173 ℃ pa kutentha kwa 130 ℃ mumlengalenga. Kutsika kwake kwamafuta kumakhala kofanana ndi PET pambuyo pa mphindi 30 pa kutentha kwa 130 ℃ mumlengalenga, ndipo kutsika kwake kumakhala kofanana ndi PET pambuyo pa mphindi 30 pa kutentha pafupifupi 215%;

(4) Kukana kuvala bwino. Chifukwa cha kusinthasintha kwake komanso ntchito yake yosweka, imakhala ndi kukana kwamphamvu kwambiri;

(5) Wopepuka. Kukoka kwapadera kwa singano ya polypropylene yaifupi yokhomeredwa nonwoven geotextile ndi 0191g/cm3 yokha, yomwe ndi yochepera 66% ya PET;

(6) Hydrophobicity yabwino. Polypropylene yochepa CHIKWANGWANI singano kukhomerera nonwoven geotextile ali ndi chinyezi pafupifupi ziro, pafupifupi palibe mayamwidwe madzi, ndi kubwezeretsa chinyezi 0105%, amene pafupifupi 8 kutsika kuposa PET;

(7) Kuchita bwino kwapakati pakuyamwa. Polypropylene lalifupi fiber singano kukhomerera nonwoven geotextile palokha imakhala ndi chinyezi chochepa kwambiri (pafupifupi ziro), ndipo imakhala ndi ntchito yabwino yoyamwitsa, yomwe imatha kusamutsa madzi motsatira nsonga ya fiber kupita kumtunda;
(8) Kulephera kukana kuwala. Singano yaufupi ya polypropylene yomwe imakhomeredwa ndi nonwoven geotextiles imakhala ndi kukana kwa UV ndipo sachedwa kukalamba ndikuwola ndi kuwala kwa dzuwa;
(9) Kukana mankhwala. Ili ndi kukana bwino kwa acidity ndi alkalinity, ndipo magwiridwe ake ndi apamwamba kuposa a ulusi wa PET.
