Hydroxypropyl methylcellulose (HPMC) yog ib qho kev siv tshuaj ntxiv thiab tau siv dav hauv mortar, tab sis nws qhov cuam tshuam rau ib puag ncig kuj tau nyiam.
Biodegradability: HPMC muaj peev xwm degradation nyob rau hauv av thiab dej, tab sis nws degradation tus nqi kuj qeeb. Qhov no yog vim hais tias cov qauv ntawm HPMC muaj ib tug methylcellulose skeleton thiab hydroxypropyl sab chains, uas ua rau HPMC muaj zog stability. Txawm li cas los xij, dhau sijhawm, HPMC yuav maj mam degraded los ntawm cov kab mob thiab cov enzymes, thiab nws thiaj li hloov mus rau hauv cov tshuaj tsis muaj tshuaj lom thiab nqus los ntawm ib puag ncig.
Kev cuam tshuam rau ib puag ncig: Qee cov kev tshawb fawb tau pom tias cov khoom lag luam degradation ntawm HPMC tuaj yeem muaj qee yam cuam tshuam rau ecosystem hauv dej hauv lub cev. Piv txwv li, cov khoom degradation ntawm HPMC tuaj yeem cuam tshuam rau kev loj hlob thiab kev loj hlob ntawm cov kab mob hauv dej, yog li cuam tshuam rau kev ruaj ntseg ntawm tag nrho cov dej ecosystem. Tsis tas li ntawd, cov khoom degradation ntawm HPMC kuj tseem muaj qee yam cuam tshuam rau kev ua haujlwm ntawm microbial thiab cog kev loj hlob hauv av.
Kev tswj hwm kev pheej hmoo ib puag ncig: Txhawm rau txo qhov cuam tshuam ntawm HPMC rau ib puag ncig, qee qhov kev ntsuas tuaj yeem ua. Piv txwv li, thaum tsim thiab xaiv HPMC cov ntaub ntawv, xav txog nws qhov kev ua tau zoo degradation thiab xaiv cov ntaub ntawv nrog kev degradation ceev. Txhim kho kev siv HPMC thiab txo cov nqi ntawm cov khoom siv, yog li txo nws qhov cuam tshuam rau ib puag ncig. Tsis tas li ntawd, kev tshawb fawb ntxiv tuaj yeem ua tiav kom nkag siab txog cov txheej txheem degradation ntawm HPMC thiab qhov cuam tshuam ntawm cov khoom degradation ntawm ib puag ncig, txhawm rau ntsuas zoo dua thiab tswj hwm nws cov kev pheej hmoo ib puag ncig.
Kev ntsuam xyuas qhov cuam tshuam ib puag ncig: Qee qhov xwm txheej, nws yuav tsim nyog los ntsuas qhov cuam tshuam ib puag ncig uas yuav raug tsim tawm thaum lub sijhawm tsim khoom lossis siv HPMC. Piv txwv li, thaum Anhui Jinshuiqiao Tsev Khoom Co., Ltd. tau ua tiav qhov kev kho dua tshiab thiab nthuav dav nrog cov khoom tsim tawm txhua xyoo ntawm 3,000 tons ntawm HPMC, nws yuav tsum tau ua qhov kev ntsuam xyuas ib puag ncig raws li "Kev ntsuas rau pej xeem koom nrog Environmental. Kev soj ntsuam kev cuam tshuam" thiab tshaj tawm cov ntaub ntawv cuam tshuam los xyuas kom meej tias qhov cuam tshuam ntawm qhov project ntawm ib puag ncig yog tswj hwm qhov tsim nyog.
Kev thov hauv ib puag ncig tshwj xeeb: Daim ntawv thov HPMC hauv ib puag ncig tshwj xeeb kuj yuav tsum xav txog nws qhov cuam tshuam ib puag ncig. Piv txwv li, nyob rau hauv tooj liab-contaminated av-bentonite barrier, qhov sib ntxiv ntawm HPMC tuaj yeem ua tau zoo rau kev txo qis ntawm nws cov kev ua haujlwm los tiv thaiv kev ua haujlwm hauv ib puag ncig hlau hnyav, txo qhov sib xyaw ntawm tooj liab-contaminated bentonite, tswj cov qauv txuas ntxiv ntawm bentonite. , thiab nrog rau qhov nce ntawm HPMC sib xyaw piv, qhov kev puas tsuaj rau qhov cuam tshuam tau txo qis thiab kev ua haujlwm los tiv thaiv dej yog txhim kho.
Txawm hais tias HPMC tau siv dav hauv kev tsim kho kev lag luam, nws qhov kev cuam tshuam ib puag ncig tsis tuaj yeem tsis quav ntsej. Kev tshawb fawb tshawb fawb thiab kev tswj xyuas tsim nyog yuav tsum tau ua kom ntseeg tau tias kev siv HPMC yuav tsis muaj kev cuam tshuam rau ib puag ncig.
