100g-600g iku ume permeable polypropylene mkpụmkpụ eriri agịga tụrụ na-abụghị kpara geotextile

N'ihe gbasara mmepụta akwa na-abụghị nke a na-eji akwa ákwà, polyester (PET) na polypropylene (PP) ka bụ isi ihe eji eme ihe, na-aza ihe karịrị 95% nke ngụkọta fiber akụrụngwa eji na-abụghị kpara akwa. Geotextile nke ejiri eriri polypropylene mee site na ịpị agịga bụ polypropylene geotextile, nke a makwaara dị ka polypropylene geotextile ma ọ bụ akwa polypropylene. A na-ekewa agịga eriri eriri polypropylene dị mkpụmkpụ nke na-abụghị nke geotextiles na-ekewa ụzọ abụọ: polypropylene short fiber geotextiles na polypropylene ogologo eriri geotextiles.

Àgwà ọma nke polypropylene mkpirisi eriri agịga tụrụ na-abụghị nke geotextile gụnyere:

(1) Ike dị mma. Ike dị ntakịrị ala karịa PET, mana siri ike karịa eriri nkịtị, yana mgbaji elongation nke 35% ruo 60%; A chọrọ ike siri ike, na mgbaji elongation nke 35% ruo 60%;

(2) Ezi ngbanwe. Mgbake mgbake ngwa ngwa ya dị mma karịa eriri PET, mana ọ dị njọ karịa eriri PET n'okpuru ọnọdụ nrụgide ogologo oge; Ma n'okpuru ọnọdụ nrụgide ogologo oge, ọ dị njọ karịa eriri PET;

(3) Nguzogide okpomọkụ na-adịghị mma. Ebe na-eme ka ọ dị nro dị n'etiti 130 ℃ na 160 ℃, ebe agbaze ya dị n'etiti 165 ℃ na 173 ℃. Ya thermal shrinkage rate ranges from 165 ℃ ka 173 ℃ n'ebe okpomọkụ nke 130 ℃ na ikuku. Ya thermal shrinkage ọnụego bụ ihu ọma otu PET mgbe 30 nkeji na okpomọkụ nke 130 ℃ na ikuku, na shrinkage ọnụego bụ ihu ọma otu PET mgbe 30 nkeji na okpomọkụ nke gburugburu 215%;

(4) Ezigbo mgbochi iyi. N'ihi ịdị mma ya dị mma na mgbaji a kapịrị ọnụ, ọ nwere nguzogide iyi mara mma;

(5) Dị fechaa. Nnukwu ike ndọda nke polypropylene mkpirisi eriri eriri ọkpọ na-abụghị nke geotextile bụ naanị 0191g/cm3, nke na-erughị 66% nke PET;

(6) Ezigbo hydrophobicity. Polypropylene obere eriri eriri ọkpọ ọkpọ nonwoven geotextile nwere mmiri ọdịnaya nso efu, ọ fọrọ nke nta ka ọ dịghị mmiri absorption, na a mmiri nwetaghachi nke 0105%, nke bụ banyere 8 ugboro ala karịa PET;

(7) Ọma isi suction arụmọrụ. Polypropylene mkpụmkpụ eriri agịga punched nonwoven geotextile n'onwe ya nwere nnọọ ala mmiri absorption (fọrọ nke nta efu), na nwere ezi core absorption arụmọrụ, nke nwere ike ibufe mmiri tinyere eriri axis n'elu elu;
(8) Nguzogide ọkụ na-adịghị mma. Polypropylene obere eriri eriri ọkpọ ọkpọ nonwoven geotextiles nwere adịghị mma UV eguzogide ma na-adịkarị mfe ịka nká na ire ere n'okpuru ìhè anyanwụ;
(9) Nguzogide kemịkalụ. Ọ nwere ezigbo nguzogide acidity na alkalinity, yana arụmọrụ ya dị elu karịa nke eriri PET.
