Hauv cov haujlwm engineering zais cia—xws li cov qhov av, cov tsheb ciav hlau hauv av, thiab cov chaw hauv av—cov ntaub thaiv dej tsis yog tsuas yog ua cov teeb meem rau kev cais dej xwb, tab sis kuj yog "cov khoom yooj ywm" uas koom nrog kev tswj kev ntxhov siab ntawm cov qauv. Ua ib lub chaw tsim khoom tshwj xeeb hauv thaj chaw ntawm geosynthetics, Shandong Hongyue Environmental Engineering Co., Ltd. (tom qab no hu ua "Hongyue Environmental") tau siv nws cov kev txawj ntse tob hauv EVA (Ethylene-Vinyl Acetate Copolymer) cov ntaub thaiv dej los tsim ib lub kaw lus tsim kho uas muaj kev tshawb fawb, nruj, thiab tus qauv. Los ntawm peb txoj kev tseem ceeb—"kev xaiv cov khoom siv meej, kev vuam zoo, thiab kev nruj tus qauv"—lub tuam txhab siv tag nrho cov khoom tshwj xeeb ntawm EVA daim ntaub, suav nrog kev ntev siab, kev tiv taus kub qis, thiab lub zog tsim kua muag, yog li tsim kom muaj kev tiv thaiv dej tsis nkag rau ntau yam haujlwm engineering.
Kauj Ruam Ib: Kev Xaiv Khoom Siv Kom Tseeb thiab Kev Npaj Cov Khoom Siv - Tso Lub Hauv Paus Zoo Kawg Nkaus
Ib qho project tiv thaiv dej zoo pib nrog kev tswj cov khoom siv kom meej. Hongyue Environmental's EVA waterproofing membranes siv cov khoom zoo Ethylene-Vinyl Acetate Copolymer ua lawv cov khoom siv raw tseem ceeb; lawv qhia txog kev ywj pheej zoo li roj hmab, muaj kev ywj pheej zoo heev hauv qhov kub qis (tswj tau yooj yim txawm tias nyob rau hauv qhov kub txias txij li -30 ° C txog -35 ° C), thiab muaj lub zog rhuav tshem siab. Ua ntej kev tsim kho, lub substrate yuav tsum tau ua tiav kev npaj ua tib zoo: qhov chaw hauv paus yuav tsum tiaj tus, khov kho, thiab tsis muaj qhov tsis sib xws lossis cov khoom ntse, tib lub sijhawm ua kom nws tsis muaj dej sawv, roj av, thiab hmoov av. Nyob ntawm qhov loj ntawm qhov project thiab nws qhov chaw ua haujlwm tshwj xeeb, Hongyue Environmental muaj cov EVA waterproofing membranes hauv ntau qhov tuab - txij li 0.5 hli txog 2.5 hli - kom ntseeg tau tias muaj kev sib npaug zoo tshaj plaws ntawm kev ua haujlwm ntawm cov khoom siv thiab cov kev xav tau engineering.
Kauj Ruam Ob: Cov Txheej Txheem Vuam Uas Zoo - Txheeb Xyuas Lub Neej Siv Tau ntawm Lub Tshuab Tiv Thaiv Dej
Thaum lub sijhawm tsim kho, qhov kev ntseeg tau ntawm daim ntaub thaiv dej nyob ntawm 90% ntawm qhov zoo ntawm kev vuam cua kub. Pab pawg kws tshaj lij ntawm Hongyue Environmental hais tias qhov kev nkag siab yuam kev ntawm kev kho vuam tsuas yog "kev ua haujlwm npog" yuav tsum raug tso tseg; hloov chaw, nws yuav tsum tau muab qhov tseem ceeb ua lub hauv paus, txheej txheem tseem ceeb. Kev tsim kho yuav tsum tau ua tiav siv cov tshuab vuam tshwj xeeb lossis cov phom vuam cua kub, nrog rau qhov kub ntawm qhov cua tawm tswj hwm nruj me ntsis hauv qhov ntau ntawm 320 ° C txog 380 ° C. Ua ntej vuam, qhov dav ntawm cov ntawv membrane sib tshooj yuav tsum tau tswj hwm meej ntawm 70 hli thiab 100 hli, thiab yuav tsum siv txhuam hlau los tshem tawm cov hmoov av lossis cov txheej oxidized ntawm thaj chaw sib tshooj. Thaum lub sijhawm vuam, qhov kub siab raug siv los yaj cov khoom siv EVA, ua raws li kev siv lub siab kom sib xyaw cov txheej rau hauv ib qho, sib koom ua ke. Kev txheeb xyuas tom qab vuam muaj peb kauj ruam kev tshuaj xyuas nruj: Ua ntej, kev tshuaj xyuas pom tau ua kom ntseeg tau tias cov xov hlau zoo li sib xws, pob tshab, zoo li iav tiav, tsis muaj npuas lossis wrinkles. Qhov thib ob, yuav tsum tau kuaj xyuas seb daim hlau puas tawg; thaum lub zog tensile raug siv rau ntawm qhov vuam, nws yuav tsum tsis tawg. Qhov thib peb, yog tias tsim nyog, yuav tsum tau kuaj xyuas kom paub tseeb tias qhov kev puas tsuaj ntawm lub zog tseem nyob hauv qhov txwv tsis pub dhau.
Kauj Ruam 3: Kev Nruj thiab Kev Tso Tawm Txog Kev Tshawb Fawb—Tshem Tawm Qhov Kev Pheej Hmoo ntawm "Kev Vuam Cuav"
Thaum lub sijhawm tsim kho hauv thaj chaw nyuaj—xws li cov qhov av—qhov hnyav ntawm cov khoom siv tuaj yeem ua rau nws poob qis, ua rau "kev sib txuas cuav" (cov seams tsis tiav lossis tsis muaj zog). Hongyue Environmental Protection tshwj xeeb hais txog qhov tsim nyog ntawm kev siv txoj kev "zoned tensioning thiab segmented welding". Qhov no suav nrog kev ruaj ntseg daim nyias nyias rau lub substrate siv cov slings tshwj xeeb uas sib nrug li 300mm; kev ntxhov siab ces raug tso tawm ntu los ntawm ntu, nrog rau kev vuam ua tib lub sijhawm. Txoj kev no zoo tiv thaiv qhov tshwm sim ntawm cov vuam cuav los ntawm cov khoom siv poob qis hauv qab nws qhov hnyav, yog li ua kom muaj kev sib txuas nruj, sib ze ntawm daim nyias nyias thiab cov qauv txhawb nqa tseem ceeb. Ntxiv mus, EVA waterproofing membranes qhia txog kev sib raug zoo dav dav nrog ntau yam nplaum; thaum lub sijhawm kho kom ntxaws ntawm cov ces kaum, cov yeeb nkab nkag mus, thiab lwm qhov chaw nyuaj, cov nplaum tshwj xeeb tuaj yeem siv los ua kom tiav kev sib khi sai thiab zoo, yog li txhim kho qhov tsis nkag ntawm lub kaw lus tiv thaiv dej.
Siv cov txheej txheem kev tsim kho no, Shandong Hongyue Environmental Protection's EVA waterproofing membranes muaj peev xwm ua kom pom tseeb lawv cov txiaj ntsig tseem ceeb - suav nrog kev tiv thaiv zoo rau hydrolysis, tiv thaiv kev nkag mus rau hauv paus, thiab lub neej ntev.
