Kev ntxhov siab et cellulose ether HPMC / MHEC cov khoom lag luam hauv kev kho cov neeg muaj nyiaj txiag tuaj yeem txhim kho cov yam ntxwv hauv qab no:
· Txhim kho dej rov qab
· Muaj zog zuj zus tsis kam thiab muaj zog
· Txhim kho cov nplaum muaj zog ntawm cov neeg nplua khoom.
Cellulose ether rau kev kho neeg tsis muaj neeg nyob
Kev khib nyiab kho tau zoo tshaj plaws ua ntej sib xyaw ua ke, cov khoom sib xyaw ua ke, cov kab ke sib xyaw ua ke, cov kab ke tshwj xeeb Kev tawg ua rog, spalling, nthuav tawm cov txuj ci, thiab lwm yam, kom rov ua haujlwm zoo ntawm cov qauv ua vaj tse.
Nws kuj tseem siv tau ua cov fiber fiber proplectived lawb cug Cov khoom yog ntxiv nrog ntau hom molecular molecular polymer modifiers, refispersible polymer hmoov thiab anti-cracking fibers. Yog li ntawd, nws muaj cov haujlwm ua haujlwm zoo, cov tshuaj nplaum, impingionbility, tev-thim tawm tsam, carbonation tsis kam, steel xeb tsis kam thiab muaj zog tiv taus.
Cov Lus Qhia Siv Ua
1. Txiav txim siab qhov chaw kho. Kev kho kho cov kev kho yuav tsum yog 100mm loj dua li thaj chaw puas tsuaj tiag. Txiav los yog txaug tawm ntawm ntug av ntawm cov pob zeb kho kom zoo nkauj nrog ≥5mm kom tsis txhob thinning ntawm ntug ntawm thaj chaw kho.
2. Huv si cov hmoov av ntab thiab roj nyob rau saum npoo ntawm cov qhob txheej hauv thaj chaw kho, thiab tshem cov seem xoob.
3. Tu kom huv thiab khib nyiab ntawm cov npoo ntawm cov kab hlau nthuav tawm hauv thaj chaw kho.
4. Lub pob zeb ua ke txheej hauv thaj chaw kho kom huv yuav raug txiav lossis kho nrog pawg neeg kho mob sib txuam.
5. Siv cua twj tso pa lossis dej kom ntxuav cov npoo av hauv thaj chaw kho, thiab tsis muaj dej ntshiab yuav tsum tau tso tseg thaum lub sijhawm tom ntej.
6. Do lub siab-zog kho cug raws li cov kev pom zoo sib xyaw ntawm 10-20% (qhov hnyav piv) dej. Mechanical tov yog txaus rau 2-3 cov ntsiab lus thiab nws yog conducive rau qhov zoo thiab nrawm ntawm kev sib xyaw. Los ntawm txhais tes kev sib xyaw yuav tsum yog ntawm 5 ntsiab lus los xyuas kom muaj kev sib xyaw ua ke.
7. Lub siab-zog kho cug uas tau sib xyaw ua ke plasters tuaj yeem yog plastered, thiab cov tuab ntawm ib plaster yuav tsum tsis pub tshaj 10mm. Yog tias txheej plastering yog tuab, ib txheej fawm kib thiab ntau txoj kev tsim qauv tsim yuav tsum tau siv.
