Cov ntaub ntawv raw ntawm cov nyom dagfeem ntau yog polyethylene (PE) thiab polypropylene (PP), thiab polyvinyl chloride thiab polyamide kuj siv tau. Cov nplooj yog pleev xim ntsuab kom zoo li cov nyom ntuj, thiab yuav tsum ntxiv cov tshuaj absorbers ultraviolet. Polyethylene (PE): Nws zoo li mos dua, thiab nws qhov tsos thiab kev ua kis las ze rau cov nyom ntuj, uas cov neeg siv tau txais dav. Nws yog cov khoom siv raw siv dav tshaj plaws rau cov nyom dag fiber hauv khw. Polypropylene (PP): Cov nyom fiber nyuaj dua, feem ntau haum rau cov chaw ua si ntaus pob tesniv, chaw ua si, txoj kev khiav lossis kho kom zoo nkauj. Qhov kev tiv thaiv hnav yog qhov phem dua li polyethylene me ntsis. Nylon: Nws yog cov khoom siv raw thaum ntxov rau cov nyom dag fiber thiab yog rau tiam neeg ntawmcov nyom dag fiber.
Cov Khoom Siv Cov nyom dag muaj 3 txheej ntawm cov ntaub ntawv. Cov txheej hauv qab yog tsim los ntawm cov txheej av compacted, txheej xuab zeb thiab txheej asphalt lossis concrete. Cov txheej hauv qab yuav tsum tau khov kho, tsis deformed, du thiab impermeable, uas yog, ib qho chaw ua si dav dav. Vim yog thaj chaw loj ntawm thaj chaw hockey, cov txheej hauv qab yuav tsum tau ua tib zoo thaum lub sijhawm tsim kho kom tiv thaiv kev poob. Yog tias ib txheej pob zeb raug tso, cov pob qij txha nthuav dav yuav tsum tau txiav tom qab cov pob zeb kho kom tiv thaiv kev nthuav dav thermal deformation thiab tawg. Saum toj no txheej hauv qab yog ib txheej buffer, feem ntau yog ua los ntawm roj hmab lossis yas ua npuas ncauj. Roj hmab muaj qhov elasticity nruab nrab thiab tuab ntawm 3 ~ 5 hli. Yas ua npuas ncauj pheej yig dua, tab sis muaj qhov elasticity tsis zoo thiab tuab ntawm 5 ~ 10 hli. Yog tias nws tuab dhau, cov nyom yuav mos dhau thiab yooj yim rau sag; yog tias nws nyias dhau, nws yuav tsis muaj elasticity thiab yuav tsis ua lub luag haujlwm buffering. Cov txheej buffer yuav tsum tau txuas nrog cov txheej hauv qab, feem ntau nrog cov roj hmab dawb lossis kua nplaum. Cov txheej thib peb, uas kuj yog txheej saum npoo, yog cov txheej turf. Raws li qhov zoo li ntawm qhov chaw tsim khoom, muaj cov nyom fluff, cov nyom nylon puag ncig, cov nyom polypropylene fiber zoo li nplooj, thiab cov nyom permeable uas muaj cov nylon filaments. Cov txheej no kuj yuav tsum tau nplaum rau cov roj hmab lossis cov yas ua npuas ncauj nrog latex. Thaum lub sijhawm tsim kho, cov kua nplaum yuav tsum tau siv tag nrho, nias kom nruj, thiab tsis muaj wrinkles tuaj yeem tsim. Txawv teb chaws, muaj ob hom txheej nyom: 1. Cov fibers zoo li nplooj ntawm cov txheej nyom yog nyias dua, tsuas yog 1.2 ~ 1.5 hli; 2. Cov fibers turf yog tuab dua, 20 ~ 24 hli, thiab quartz tau sau rau ntawm nws yuav luag mus rau sab saum toj ntawm cov fiber.
Kev tiv thaiv ib puag ncig
Polyethylene, cov khoom tseem ceeb ntawm cov nyom dag, yog cov khoom siv uas tsis lwj. Tom qab 8 txog 10 xyoo ntawm kev laus thiab tshem tawm, nws tsim ntau cov khib nyiab polymer. Hauv cov tebchaws txawv teb chaws, nws feem ntau rov ua dua thiab lwj los ntawm cov tuam txhab, thiab tom qab ntawd rov ua dua thiab rov siv dua. Hauv Suav teb, nws tuaj yeem siv ua lub hauv paus rau kev tsim kho txoj kev. Yog tias qhov chaw hloov mus rau lwm yam kev siv, txheej hauv paus uas ua los ntawm asphalt lossis concrete yuav tsum tau tshem tawm.
Cov txiaj ntsig
Cov nyom dag muaj qhov zoo ntawm qhov ci ntsa iab, ntsuab txhua xyoo puag ncig, ci ntsa iab, ua haujlwm zoo, lub neej ntev, thiab tus nqi kho qis.
Teeb meem thaum lub sijhawm tsim kho:
1. Qhov loj ntawm cov cim tsis raug txaus, thiab cov nyom dawb tsis ncaj.
2. Lub zog ntawm txoj siv sib koom ua ke tsis txaus lossis cov kua nplaum nyom tsis siv, thiab cov nyom tig mus rau saum.
3. Txoj kab sib koom ua ke ntawm qhov chaw pom tseeb,
4. Qhov kev taw qhia ntawm cov nyom silk lodging tsis tau teem caij tas li, thiab qhov sib txawv ntawm xim reflection tshwm sim.
5. Qhov chaw ntawm qhov chaw tsis sib npaug vim yog kev txhaj tshuaj xuab zeb tsis sib npaug thiab cov roj hmab me me lossis cov nyom tsis tau ua tiav ua ntej.
6. Qhov chaw muaj ntxhiab tsw lossis xim tsis zoo, uas feem ntau yog vim qhov zoo ntawm cov khoom siv filler.
Cov teeb meem saum toj no uas yuav tshwm sim thaum lub sijhawm tsim kho tuaj yeem zam tau tsuav yog ua tib zoo saib xyuas me ntsis thiab ua raws li cov txheej txheem tsim cov nyom dag.
