QualiCell cellulose ether HPMC / MHEC cov khoom hauv kev kho mortars tuaj yeem txhim kho cov khoom hauv qab no:
· Txhim kho dej tuav
· Ua kom tawg tsis kam thiab compressive zog
· Txhim kho lub zog adhesion ntawm mortars.
Cellulose ether rau Kho Mortars
Kho mortar yog ib qho zoo tshaj plaws pre-mixed, shrinkage-compensated mortar ua los ntawm cov cements xaiv, graded aggregates, sib sib zog nqus fillers, polymers thiab tshwj xeeb additives.Kev kho mortar feem ntau yog siv los kho qhov chaw puas ntawm cov pob zeb ua vaj tse xws li kab noj hniav, honeycombs, breakages, spalling, exposed tendons, thiab lwm yam, los kho cov kev ua tau zoo ntawm cov pob zeb ua qauv.
Nws kuj tseem siv tau los ua carbon fiber reinforced leveling mortar, high-performance masonry mortar, thiab plastering leveling protective mortar for steel strand reinforcement in buildings (structures). Cov khoom yog ntxiv nrog ntau hom kev hloov pauv siab molecular polymer, roj hmab hmoov thiab cov fibers los tiv thaiv kev tawg. Yog li ntawd, nws muaj kev ua haujlwm zoo, adhesion, impermeability, tev tsis kam, khov-thaw tsis kam, carbonization tsis kam, tawg tsis kam, steel xeb kuj thiab siab zog.
Cov lus qhia kev tsim kho
1. Txiav txim qhov chaw kho. Kev kho kho ntau yam yuav tsum yog 100mm loj dua qhov chaw puas tsuaj. Txiav los yog chisel tawm ntawm ntug ntsug ntawm qhov chaw kho pob zeb nrog qhov tob ntawm ≥5mm kom tsis txhob thinning ntawm ntug ntawm qhov chaw kho.
2. Ntxuav cov plua plav thiab cov roj nyob rau saum npoo ntawm cov pob zeb hauv paus txheej hauv qhov chaw kho, thiab tshem tawm cov khoom xoob.
3. Ntxuav cov xeb thiab cov khib nyiab ntawm qhov chaw ntawm cov hlau tuav hauv qhov chaw kho.
4. Cov pob zeb hauv paus txheej hauv qhov chaw kho kom huv yuav tsum tau chipped los yog kho nrog tus neeg saib xyuas kev sib txuas ua ke.
5. Siv lub twj tso kua mis lossis dej los ntxuav qhov chaw ntawm lub hauv paus pob zeb hauv qhov chaw kho, thiab tsis muaj dej ntshiab yuav tsum tau tso tseg thaum lub sijhawm ua haujlwm tom ntej.
6. Do lub siab-lub zog kho mortar raws li kev pom zoo sib xyaw piv ntawm 10-20% (qhov hnyav piv) ntawm dej. Kev sib xyaw tshuab yog txaus rau 2-3 cov ntsiab lus thiab nws yog qhov tsim nyog rau qhov zoo thiab ceev ntawm kev sib xyaw. Kev sib xyaw ua ke yuav tsum nyob ntawm 5 lub ntsiab lus kom ntseeg tau tias sib xyaw ua ke.
7. Lub siab-lub zog kho mortar uas tau muab sib xyaw tuaj yeem plastered, thiab lub thickness ntawm ib lub plaster yuav tsum tsis pub tshaj 10mm. Yog tias txheej txheej plaster yog tuab, txheej txheej thiab ntau txheej plastering yuav tsum tau siv.
