I-100g-600g enalithi ephefumulayo ye-polypropylene yefayibha emfushane ebhotshozwe nge-geotextile engalukiwe

Emkhakheni wokukhiqizwa kwendwangu engalukiwe, i-polyester (PET) kanye ne-polypropylene (PP) kuseyizinto zokusetshenziswa eziyinhloko, ezibalwa ngaphezu kwama-95% wesamba sezinto zokusetshenziswa kwefayibha ezisetshenziswa ezindwangu ezingalukiwe. I-geotextile eyenziwe nge-polypropylene fibers ngokusebenzisa inaliti yokubhoboza i-polypropylene geotextile, eyaziwa nangokuthi i-polypropylene geotextile noma indwangu ye-polypropylene. Inalithi ye-polypropylene i-fiber emfushane ebhontshiwe ama-geotextiles angalukiwe ahlukaniswe abe izinhlobo ezimbili: i-polypropylene i-fiber geotextiles emfushane kanye ne-polypropylene ende yefayibha geotextiles.

Izici ze-polypropylene inaliti yefayibha emfushane ebhontshiwe i-nonwoven geotextile zifaka:

(1) Amandla amahle. Amandla angaphansi kancane kune-PET, kodwa anamandla kunemicu evamile, enobude bokuphuka okungama-35% kuya ku-60%; Kudingeka amandla aqinile, ngokunwebeka kwe-fracture kusuka ku-35% kuya ku-60%;

(2) Ukunwebeka okuhle. Ukubuyiselwa kwayo okunwebekayo ngokushesha kungcono kune-PET fiber, kodwa kubi kune-PET fiber ngaphansi kwesimo sokucindezeleka isikhathi eside; Kodwa ngaphansi kwezimo zokucindezeleka zesikhathi eside, kubi kakhulu kunemicu ye-PET;

(3) Ukumelana nokushisa okungalungile. Iphuzu layo lokuthambisa liphakathi kuka-130 ℃ no-160 ℃, futhi indawo yayo yokuncibilika iphakathi kuka-165 ℃ no-173 ℃. Izinga layo lokushwabana okushisayo lisukela ku-165 ℃ ukuya ku-173 ℃ endaweni yokushisa engu-130 ℃ emkhathini. Izinga layo lokushwabana okushisayo ngokuyisisekelo liyafana ne-PET ngemva kwemizuzu engama-30 ezingeni lokushisa elingu-130 ℃ emkhathini, futhi izinga lokuncipha ngokuyisisekelo liyafana ne-PET ngemva kwemizuzu engama-30 ekushiseni okungaba ngu-215%;

(4) Ukumelana nokugqoka okuhle. Ngenxa yokuqina kwayo okuhle kanye nomsebenzi othize wokuphuka, inokumelana okuhle kakhulu nokugqoka;

(5) Elula. Amandla adonsela phansi e-polypropylene inaliti yefayibha emfushane ebhontshiwe i-nonwoven geotextile ingu-0191g/cm3 kuphela, engaphansi kuka-66% we-PET;

(6) I-hydrophobicity enhle. Inalithi ye-polypropylene ye-fiber emfushane ebhontshiwe i-nonwoven geotextile inomswakama osondele ku-zero, cishe awukho ukumuncwa kwamanzi, kanye nokutholwa komswakama okungu-0105%, okungaphansi ngokuphindwe ka-8 kune-PET;

(7) Ukusebenza kahle kwe-core suction. Inalithi ye-polypropylene ye-fiber emfushane ebhontshiwe i-nonwoven geotextile ngokwayo inokumunca umswakama ophansi kakhulu (cishe u-zero), futhi inokusebenza okuhle kokumuncwa okuyisisekelo, okungadlulisa amanzi eduze kwe-axis ye-fiber endaweni yangaphandle;
(8) Ukumelana nokukhanya okungalungile. Inalithi ye-polypropylene ye-fiber emfushane ebhontshiwe ama-geotextiles angalukiwe anokumelana kahle ne-UV futhi ajwayele ukuguga nokubola ngaphansi kokukhanya kwelanga;
(9) Ukumelana namakhemikhali. Inokumelana okuhle ne-acidity kanye ne-alkalinity, futhi ukusebenza kwayo kuphakeme kunokwemicu ye-PET.
