Xaiv cov khoom rau tsim ntawm vaj paths thiab cheeb tsam hauv zos, koj yuav tsum coj mus rau hauv tus account tsis tsuas yog nws zoo nkauj peev xwm, tab sis kuj durability thiab practicality.
Cov vuas tuaj yeem tau muaj ntau hom, ntau thiab tsawg, xim, thickness thiab cov khoom, tab sis nws yuav tsum muaj lub zog siab thiab ua hauj lwm rau sab nrauv txhoj puab heev. Xws li cov khoom uas yog cov nplua nuj ntawm cov pob zeb paving niaj hnub no. Cov khoom siv no yuav luag tshiab, tab sis nws twb tau tswj kom pom nws tus kheej zoo.
Ntau cov kev yees duab thiab xaiv cov khoom siv raw
Cov lus ntawm cov polymer sand paving vuas muaj xws li peb yam khoom:
- Xuab zeb (li 75%);
- High-pressure propylene los yog propylene;
- Dyes ntawm inorganic keeb kwm.
Qhov kev ntxhib los mos thiab lub zog ntawm cov khoom yog nyob ntawm qhov zoo ntawm cov khoom siv raw. Hauv cov txheej txheem ntau lawm, tshwj xeeb saib xyuas yog them nyiaj rau feem ntau ntawm cov xuab zeb. Ua ntej siv, nws yog zoo ntxuav, sieved thiab calcined ntawm high kub. Qhov loj ntawm qhov hais yog qhov tseem ceeb, yog li ntawd, xuab zeb ntawm medium loj yog xaiv.
Tom qab sib tov tag nrho cov khoom xyaw rau homogeneous kev ntxhib los mos thiab xim, qhov sib tov yog xa mus rau ib qho tshwj xeeb extruder, qhov twg nws yog ib zaug dua tov thiab melted. Tom qab ntawd lub sib tov yog xa nyob rau hauv xovxwm thiab daim hlau ntawm Desired loj thiab cov duab yog tsim los ntawm nws.
Xws li lub pobzeb tuaj yeem tiv taus kub siab txog -70 ° C thaum nws tsis tawg thiab tsis tawg tsis zoo li polymer sand qhob paving vuas.
Cov yam ntxwv thiab cov khoom ntawm cov khoom
Polymer sand sidewalk vuas muaj cov yam ntxwv nram qab no:
- qib siab hnyav hnyav thiab lub zog;
- dej tsis haum (noo noo tsis nkag mus hauv, tab sis accumulates nyob rau saum npoo nyob rau hauv daim ntawv ntawm droplets);
- tsis kam siv tshuaj txhawm rau tshuaj;
- lub teeb yuag;
- withstand impressive tsawg kub;
- yooj yim ntawm installation;
- ntau hom duab, qhov ntau thiab tsawg ntawm cov zauv feem.
Tab sis nws yuav tsum nco ntsoov hais tias cov khoom yuav nthuav nyob rau hauv tus ntawm high kub, yog li lub tso ntawm polymer Sandwich paving vuas yog ua noj mus rau hauv tus account qhov tsim nyog khoob.
Cov secrets ntawm installation
Cov yam ntxwv ntawm polymer sand vuas tso cai rau siv nws ob qho tib si nyob rau hauv nroog loj thiab rau qhov kev npaj ntawm lub caij ntuj sov chaw nyob. Kev npaj ua tiav pib nrog lub hauv paus uas tso txoj kev siv tshuab yuav nyob ntawm seb. Nws tuaj yeem yog ob hom: zeb los yog gravel.
Laying nyob rau hauv lub hauv paus ntawm xuab zeb yog nqa tawm nyob rau hauv ib txoj kev zoo sib xws:
- Los ntawm qhov chaw uas ib ncig ntawm qhov twg lub tiling yuav pw, lub Upper kheej ntawm cov av (15-20 cm) yog muab tshem tawm.
- Tom qab ntawd lub hauv paus yog theem thiab tamped noj mus rau hauv tus account lub slope.
- Nyob rau hauv cov npoo yog tshwj xeeb curbs, uas tsa ib txheej ntawm cov xuab zeb nyob rau hauv 5cm, spilled dej thiab kuj tamped.
- Curb marking yog nqa tawm, tom qab ntawd txhim kho ntawm cov pob zeb curb nram qab no.
- Ib txheej ntawm geotextile nrog ib tug sib tshooj ntawm 15-20 cm yog superimposed on npaj compacted av.
- From saum toj no, rau ib txheej ntawm geotextile, ib txheej ntawm cov xuab zeb yog poured, ces nws yog spilled los ntawm dej, compacted thiab leveled. Muaj ntau ntau txheej ntawm no.
- Tsis tas li ntawd, cov vuas twb pw nrog ib tug sib txawv ntawm 3-5 hli thiab dlhos siv ib tug rubber rauj.
- Cov nqaws dej muaj cov xuab zeb tom qab tso.
Poob rau hauv paus gravel muab rau kev siv ntawm thawj 4 cov ntsiab lus, thiab tom qab ntawd ces qhov chaw ntawd muaj cov pob zeb uas muaj pob zeb thiab sib zog. Cov pobzeb yog muab ntim rau hauv 5-10 cm. Cov vuas luaj muaj ntiv nplhaib lossis qhob sib xyaw (2-3 cm txheej), cov nqaws dej puv nrog cov xuab zeb los yog sib xyaw qhuav ntawm cov pob zeb thiab cov xuab zeb. Tom qab ua kom tiav qhuav, lawv yuav tsum tau so nrog txhuam txhuam tawv.
