Niaj hnub no lub caij nyoog uas cov peev txheej rov ua dua tshiab tau txais kev saib xyuas ntau ntxiv, kev pov tseg cov log tsheb pov tseg tau dhau los ua qhov txuas tsis tseem ceeb. Cov khib nyiab loj ntawm cov log tsheb tsis yog nyob hauv av xwb tab sis kuj ua rau muaj hluav taws kub thiab muaj kuab paug ib puag ncig. Yuav ua li cas hloov lawv mus rau hauv cov peev txheej muaj txiaj ntsig yog qhov teeb meem tseem ceeb rau kev ua tiav kev txhim kho kom ruaj khov.
Nws tuaj yeem hais tau tias cov khoom siv log tsheb khib nyiab yog cov khoom lag luam uas ua tau raws li qhov xav tau ntawm lub sijhawm. "Semi-cov khoom siv khib nyiab tsis siv neeg" txhais tau hais tias cov kauj ruam tseem ceeb tau ua tiav los ntawm cov tshuab, thaum thauj khoom, tshuaj xyuas, ntim khoom tiav, thiab lwm cov kauj ruam tseem xav tau qee qhov kev pabcuam phau ntawv. Qhov kev tsim no sib npaug cov nqi peev thiab kev ua haujlwm ntau lawm, tso cai rau cov tuam txhab me me - thiab nruab nrab - cov khoom siv rov ua dua tshiab los txais yuav nws, yog li txo qis ntawm cov ntawv thov kev lag luam.
Nws txoj haujlwm ua haujlwm feem ntau tuaj yeem suav nrog hauv cov kauj ruam tseem ceeb hauv qab no:
1. Tyre pretreatment - Lub log tsheb txiav tshuab ua qhov pib decomposition ntawm cov log tsheb, ua rau cov kauj ruam tom ntej.
2. Kev sib cais ntawm cov hlaws hlau - Cov hlaws ib feem ntawm lub log tsheb muaj cov hlua khi hlau kom lub log kom nruj rau ntawm ntug. Siv cov hlaws hlau cais, cov hlau xaim tau raug cais kom raug. Lub siab-purity steel hlau tau txais tuaj yeem siv rau kev txhaj tshuaj sandblasting steel lossis rov ua dua li qib siab- cov khoom seem hlau zoo.
3. Kev sib cais ntawm cov xaim hlau thiab roj hmab - Cov khoom siv roj hmab txiav raug xa mus rau cov khoom siv tseem ceeb, cov roj hmab tawg. Los ntawm cov txheej txheem ntawm cov chais nrog cov grooves tshwj xeeb, cov roj hmab thaiv tau rov ua dua thiab ripped. Roj hmab muaj elasticity, thaum cov hlua sab hauv cov hlau yog nkig. Nyob rau hauv tas li ntawd mechanical quab yuam, roj hmab thiab steel hlau yuav raug muab cais. Cov khoom sib tov sib xyaw ces poob rau hauv cov khoom sib txawv ntawm cov ntxaij vab tshaus vibrating, sib nqus sib nqus, thiab cua sib cais tshuab.
Cov cuab yeej siv log tsheb khib nyiab no siv cov txheej txheem rov ua dua tshiab ntawm lub cev, ua kom tsis muaj dej khib nyiab lossis tso pa tawm. Cov ntaub ntawv rov tsim dua tshiab muaj ntau daim ntawv thov, xws li siv los ua kev hloov kho hauv asphalt rau txoj kev paving, uas tuaj yeem txo cov suab nrov ntawm txoj kev thiab txhim kho asphalt siab - kub tsis kam thiab qis - kub tsis kam; lawv kuj tuaj yeem raug nias rau hauv ntau yam roj hmab hauv pem teb, cov chaw ua si, kev poob siab- nqus mats, daim nyias nyias, thiab lwm yam.
