PP Biaxial Geogrid polypropylene geogrid no ka hoʻoikaika ʻana i ke alaloa kiʻi

PP Biaxial Geogrid polypropylene geogrid no ka hooikaika alanui alanui

ʻO ka wehewehe pōkole:

Hoʻokumu ʻia ʻo PP Biaxial Geogrid mai ka Polypropylene, ua hana ʻia e ka extruding, longitudinal stretching a me ke ākea ākea.Loaʻa i ka PP Biaxial Geogrid ka ikaika tensile kiʻekiʻe ma nā ʻaoʻao longitudinal a me nā kuhikuhi.ʻO PP Biaxial Geogrid kahi hoʻolālā i hoʻopaʻa ʻia, i noi nui ʻia no ka hoʻomau ʻana i ka lepo a me nā noi hoʻoikaika.Hoʻoikaika ia i ka lepo me kona kūlana paʻa maikaʻi a me ka hana interlock mechanical ikaika.He mea kaulana loa ia e hoʻohana no ke kūkulu ʻana ʻaʻole wale no kāna hana Reinforcement maikaʻi, akā no ka mea he kūʻē maikaʻi ia i ka waikawa, alkali, corrosion a me ka ʻelemakule.

Hana ʻia ʻo PP biaxial geogrid i ka polymer ma o ka extrusion, ka hoʻokumu ʻana i ka pā, ke kaʻina hana punching a me ka longitudinal a me ka transverse stretching.Loaʻa ka ikaika tensile nui o ka mea i ka longitudinal a me ka transverse kuhikuhi, a hiki i kēia ʻano ke hāʻawi i kahi ʻoi aku ka maikaʻi o ka lawe ʻana a me ka diffusion ʻōnaehana kaulahao maikaʻi i ka lepo, kahi kūpono no ka hoʻoikaika ʻana i ka wahi nui o ke kumu kūpaʻa mau.
I ka hana ʻana o PP biaxial geogrid, e hoʻonohonoho hou ʻia nā polymers me ke kaʻina hana hoʻomehana a me ka hoʻonui ʻana, e hoʻoikaika ana i ka ikaika paʻa ma waena o nā kaulahao mole a hoʻokō i ke kumu o ka hoʻomaikaʻi ʻana i ko lākou ikaika.ʻO kona elongation he 10% ~ 15% wale nō o ka pā mua.Inā hoʻohui ʻia ke kalapona ʻeleʻele a me nā mea anti-kahiko ʻē aʻe i loko o ka geogrid, hiki ke hana ʻia i ʻoi aku ka maikaʻi o ke kūʻē ʻana i ka waikawa, alkali, corrosion a me ka ʻelemakule.

2, hiki i ka Biaxial Geogrid ke pale i ka haki ʻana a me ke kahe ʻana
