Performance Index
1. Cov khoom no muaj tus nqi txo cov dej zoo, muaj cov dej txo tau zoo nyob rau hauv qhov sib tov qis, tshwj xeeb tshaj yog nyob rau hauv cov qib siab pob zeb (saum C50), nws cov dej txo tus nqi tuaj yeem ncav cuag 38%.
2. Cov khoom no muaj lub zog zoo thaum ntxov thiab txhim khu kev qha, thiab lub zog thaum ntxov thiab kev txhim kho ntawm cov pob zeb sib xyaw rau hauv cov khoom no yog siab dua lwm hom dej reducer.
3. Cov khoom lag luam muaj cov ntsiab lus roj tsim nyog, thiab tuaj yeem hloov kho raws li qhov xav tau tiag tiag ntawm qhov project.
4. Cov khoom no tsis muaj chloride ion, sodium sulfate, nrog cov ntsiab lus alkali qis, tsis muaj corrosion rau steel tuav, yog li nws tuaj yeem txhim kho cov pob zeb ua haujlwm ntev.
5. Cov khoom no muaj qhov ruaj khov loj, cov pob zeb sib xyaw rau hauv cov khoom tuaj yeem txhim kho nws cov shrinkage thiab distortion kev ua tau zoo, thiab txo qhov kev pheej hmoo tawg.
6. Cov khoom no muaj kev tiv thaiv dej zoo heev, tsis muaj dej rho tawm, tsis muaj kev sib cais, kev ua haujlwm yooj yim dua.
7. Cov khoom no tsis muaj formaldehyde, tsis muaj ammonia tso tawm, yog ib puag ncig tus phooj ywg dej reducer

Txoj Kev Thiab Kev Ceeb Toom
1. Pom zoo sib tov ntau npaum li cas: 0.6 ~ 2.5% (xws li los ntawm cov khoom siv gel, qhov sib xyaw no yog qhov pom zoo sib xyaw, thiab qhov sib piv meej yuav tsum tau txiav txim siab thaum kawg tom qab kev sib koom ua ke sib piv raws li qhov xwm txheej tiag tiag).
2. Cov khoom no tuaj yeem muab ntxiv rau hauv lub tov khoom ib txhij nrog cov dej sib tov los tswj qhov kev ntsuas qhov yuam kev hauv Tsis pub dhau 1% thiab ncua sijhawm sib xyaw rau 30s, dej hauv cov tshuaj yuav tsum tau txiav tawm ntawm cov dej sib tov.
3. Cov khoom no yuav tsum tsis txhob rov qab siv dua nrog naphthalene water reducer, thiab yuav tsum tau them nyiaj rau kev ntxuav tawm lub tank thaum hloov cov khoom sib tov.
4. Cov khoom no yog lub raj mis thiab yuav tsum tau muab cia rau hauv qhov chaw txias thiab qhuav ntawm 0-40 ℃, xyuam xim rau cov dej tsis zoo, kev puas tsuaj thiab txee lub neej ntawm ib xyoos.
Kev Pabcuam
1. Peb lub tuam txhab tuaj yeem muab cov kev pabcuam cuam tshuam rau kev ua vaj tse pob zeb.
2. Raws li qhov xav tau ntawm tus khub, peb lub tuam txhab tuaj yeem muab cov kev pabcuam xws li kev sib xyaw ua ke tsim qauv, kev tsim kho kom zoo (lub sijhawm siv nrawm thiab txuag nqi), kev tsim kho txheej txheem, kev kho vaj tse thiab kev kho thiab lwm yam kev pabcuam.
