Cov khoom no yog ua los ntawmcov ntaub tsis yog wovenNws yog ib tiam tshiab ntawm cov khoom siv ib puag ncig zoo. Nws yog cov dej noo-pov thawj, ua pa tau, yoog tau, lub teeb, tsis kub hnyiab, yooj yim rau decompose, tsis muaj tshuaj lom thiab tsis khaus, nplua nuj xim, tsis tshua muaj nqi thiab rov ua dua tshiab.
Cov khoom siv no tuaj yeem lwj mus rau hauv av tau tom qab muab tso rau sab nraum zoov tau 90 hnub. Nws muaj lub neej ua haujlwm txog li 5 xyoos. Nws tsis muaj tshuaj lom, tsis muaj ntxhiab thiab tsis muaj cov khoom seem thaum hlawv, yog li nws tsis ua rau ib puag ncig puas tsuaj thiab tau lees paub thoob ntiaj teb tias yog cov khoom zoo rau ib puag ncig uas tiv thaiv lub ntiaj teb ecology.
Cov txiaj ntsig:
1. Lub teeb yuag: Polypropylene resin yog cov khoom siv tseem ceeb rau kev tsim khoom. Lub zog tshwj xeeb tsuas yog 0.9, tsuas yog peb feem tsib ntawm paj rwb, uas yog fluffy thiab xis nyob.
2. Tsis muaj tshuaj lom, tsis ua rau khaus: Cov khoom no tsim tawm raws li FDA cov khoom noj khoom haus raw, tsis muaj lwm yam khoom siv tshuaj lom neeg, muaj kev ua haujlwm ruaj khov, tsis muaj tshuaj lom, tsis muaj ntxhiab, thiab tsis ua rau daim tawv nqaij khaus.
3. Cov tshuaj tua kab mob thiab tshuaj tua kab mob: Polypropylene yog cov tshuaj lom neeg uas tsis muaj zog, uas tsis ua rau cov kab mob, thiab tuaj yeem cais cov kab mob thiab kab hauv cov kua. Cov tshuaj tua kab mob, alkali corrosion, thiab cov khoom tiav lawm tsis cuam tshuam rau lub zog vim yog kev yaig.
4. Cov khoom zoo: Nws yog ua los ntawm kev ncaj qha spinning polypropylene rau hauv ib lub mesh, thiab lub zog ntawm cov khoom zoo dua li cov khoom siv fiber ntau, lub zog tsis yog-directional, thiab lub zog longitudinal thiab transverse zoo sib xws.
5. Hais txog kev tiv thaiv ib puag ncig, cov khoom siv raw ntawm feem ntau cov ntaub tsis-woven siv yog polypropylene, thiab cov khoom siv raw ntawm cov hnab yas yog polyethylene. Txawm hais tias ob yam khoom muaj lub npe zoo sib xws, lawv muaj cov qauv tshuaj sib txawv heev. Cov qauv tshuaj molecular ntawm polyethylene muaj kev ruaj khov zoo thiab nyuaj heev rau decompose. Yog li ntawd, nws siv sijhawm 300 xyoo rau lub hnab yas kom decompose. Cov qauv tshuaj ntawm polypropylene tsis muaj zog, thiab cov saw molecular tuaj yeem tawg yooj yim, yog li nws tuaj yeem decompose tau zoo. Thiab nyob rau hauv daim ntawv tsis muaj tshuaj lom mus rau hauv lub voj voog ib puag ncig tom ntej, iblub hnab ntim khoom tsis yog woventuaj yeem lwj tag nrho hauv 90 hnub. Ntxiv mus, lub hnab yas tsis yog woven tuaj yeem siv dua ntau dua 10 zaug, thiab qib kev ua qias tuaj ib puag ncig tom qab pov tseg tsuas yog 10% ntawm lub hnab yas.
