Polypropylene Twisted Fibers yog cov khoom siv fiber ntau ua los ntawm polypropylene raws li cov txheej txheem sib tw, ua kom tiav ntawm kev kho mob saum npoo av. Qhov no tus txheej txheem ntau lawm tau xaus polypropylene pibers nrog cov khoom siv lub cev thiab tshuaj lom neeg tseem ceeb rau kev txhim kho cov pob zeb thiab lwm yam kev kho vaj tse. Lub sijhawm ua kom sib haum thiab sib ntswg cov txheej txheem ua kom muaj zog ntawm polypropylene fibers, thaum cov kev kho mob saum npoo av tau zoo ua kom tiav ntawm cov fibers thiab xis mas matrix. Qhov no kom ntseeg tau tias cov fibers kaw ntom nti ua ke nrog cov pob zeb ua ke, txhim kho qhov ruaj ntseg tag nrho thiab ruaj khov ntawm cov qauv.
Polypropylene Twisted fibers muaj cov accid thiab alkali corrosion, ua rau kom muaj kev ruaj khov ua tau zoo nyob rau hauv cov chaw tuag tsis ruaj khov. Qhov no ua rau lawv haum rau siv nyob rau hauv ntau cov ntawv teev tshwj xeeb, xws li hauv kev lag luam tshuaj lom neeg, kev kho kom tiav, thiab mining. Txawm hais tias muaj zog rau cov muaj zog acids, alkalis, los yog cov av noo thiab lwm yam kev ua haujlwm ntawm cov khoom siv tsis taus lossis ua haujlwm ntev ntev ntawm cov qauv ua lag luam.
Thaum kev tsim kho, kev siv polypropylene twisted fibers yog ncaj qha. Lawv tuaj yeem yooj yim sib xyaw nrog cov pob zeb ua thiab lwm yam khoom uas tsis muaj kev puas tsuaj rau cov khoom siv sib xyaw. Cov neeg siv khoom siv tsuas yog yuav tsum tau ntxiv cov fibers nrog rau aggregates rau hauv cov tov khoom, tom qab ntawd ntxiv dej thiab sib xyaw ua ke ua ke.
