I-Uniaxial tensile plastic geogrid

Uniaxial tensile plastic geogrid Isithombe Esifakiwe

incazelo emfushane:

Isebenzisa i-polymer yamangqamuzana aphezulu kanye ne-nano-scale carbon black njengezinto zokusetshenziswa eziyinhloko, ikhiqizwa ngenqubo ye-extrusion kanye ne-traction ukuze kwakhiwe umkhiqizo we-geogrid onemeshi efanayo ohlangothini olulodwa.

I-Plastiki geogrid iyinetha le-polymer eyisikwele noma elingunxande elakhiwe ngokwelula, elinganwebeka i-uniaxial kanye nokwelula kwe-biaxial ngokwezikhombisi-ndlela ezihlukene ezinwebekayo ngesikhathi sokwenziwa.Ibhoboza izimbobo eshidini le-polymer ekhishwe (ikakhulukazi i-polypropylene noma i-polyethylene ephezulu), bese yenza ukunwebeka okuqondile ngaphansi kwezimo zokushisa.Igridi enwetshiwe ngokulinganayo yenziwa ngokwelula kuphela ngobude beshidi, kuyilapho igridi enwetshiwe nge-biaxially yenziwa ngokuqhubeka nokwelula igridi enwetshiwe ngendlela eqondile ngendlela eqondile ukuya kubude bayo.

Ngenxa yokuthi i-polymer ye-geogrid yepulasitiki izohlelwa kabusha futhi iqondiswe phakathi nenqubo yokushisa nokunwetshwa ngesikhathi sokwenziwa kwe-geogrid yepulasitiki, amandla okubopha phakathi kwamaketanga amangqamuzana ayaqiniswa, futhi inhloso yokuthuthukisa amandla ayo iyafinyelelwa.Ubude bayo bungu-10% kuya ku-15% kuphela weshidi lokuqala.Uma izinto zokulwa nokuguga ezifana ne-carbon black zengezwa ku-geogrid, ingayenza ibe nokuqina okungcono njengokumelana ne-asidi, ukumelana ne-alkali, ukumelana nokugqwala kanye nokumelana nokuguga.

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

I-geogrid yendlela eyodwa

I-geogrid yendlela eyodwa yakhiwa ngokukhipha i-polymer yemolekyuli ephezulu ibe yipuleti elincane, ibhoboze inetha elivamile, bese inwebeka ngobude.Isakhiwo esibalulekile se-oval mesh ende.Lesi sakhiwo sinamandla aphezulu okudonsa kanye ne-tensile modulus, ikakhulukazi imikhiqizo yenkampani yethu inesigaba sokuqala esiphezulu (izinga lokwelula lika-2% --- 5% ) amandla okudonsa kanye ne-tensile modulus.Ihlinzeka ngendlela efanelekile yokuthwala amandla kanye nesistimu ye-interlock ye-diffusion yomhlabathi.Umkhiqizo unamandla amakhulu okudonsa (>150Mpa) futhi ulungele inhlabathi ehlukahlukene.Kuyinto esetshenziswa kabanzi yokuqinisa.

Incazelo Yomkhiqizo

Ukucaciswa komkhiqizo:
TGDG35, TGDG50, TGDG80, TGDG120, TGDG160, TGDG260, TGDG300 njll., ububanzi buyi-1~3meters.

Izici Zomkhiqizo:
1. Qinisa umbhede womgwaqo, uthuthukise ukuzinza kanye namandla okuthwala, futhi ukwazi ukumelana nemithwalo emikhulu eshintshanayo;
2. Vimbela ukuguqulwa kanye nokuqhekeka kwe-subgrade okubangelwa ukulahlekelwa kwezinto ezisetshenziswayo;
3. Thuthukisa umthamo wokugcwalisa wodonga olubambayo futhi ulondoloze izindleko zobunjiniyela.

Izimo zohlelo lokusebenza

1.ukuqinisa imigwaqo emigwaqeni emikhulu, imigwaqo kamasipala, izitimela, izikhumulo zezindiza, njll. kanye nokuqinisa amadamu emifuleni namadamu olwandle;
2.Ukubiywa kwamasimu ezithelo, amasimu emifino, imfuyo, umhlaba, njll.;
3.Ubunjiniyela obuqinisiwe bokugcina inhlabathi izindonga zemigwaqo, imigwaqo kamasipala, izitimela, izikhumulo zezindiza, amadamu emifula namadamu olwandle.
