☑ Cia thiab xa khoom
Nws yuav tsum tau muab khaws cia thiab xa mus nyob rau hauv qhuav thiab huv si tej yam kev mob nyob rau hauv nws cov thawj pob daim ntawv thiab deb ntawm tshav kub. Tom qab lub pob qhib rau kev tsim khoom, yuav tsum tau ua kom nruj rov qab sealing kom tsis txhob muaj dej noo.
Pob: 25kg / hnab, ntau txheej ntawv yas composite hnab nrog square hauv qab valve qhib, nrog puab txheej polyethylene zaj duab xis hnab.
☑Txee lub neej
Lub sijhawm lav yog ob xyoos. Siv nws kom ntxov li sai tau nyob rau hauv qhov kub thiab txias, thiaj li tsis ua rau kom qhov tshwm sim ntawm caking.
☑Khoom ruaj ntseg
Hydroxypropyl methyl cellulose HPMC LK40M tsis yog cov khoom siv phom sij. Cov ntaub ntawv ntxiv txog kev nyab xeeb yog muab rau hauv Cov Ntaub Ntawv Kev Nyab Xeeb Cov Ntaub Ntawv.
FAQS
Hydroxypropyl methylcellulose (HPMC) yog cellulose ethers uas tau muaj cov pab pawg hydroxyl ntawm cov cellulose saw hloov rau methoxy lossis hydroxypropyl pawg.It yog tsim los ntawm tshwj xeeb etherification ntawm cov paj rwb ntshiab heev cellulose nyob rau hauv alkaline tej yam kev mob. Nyob rau hauv xyoo tas los no, HPMC, raws li cov khoom siv ua haujlwm, feem ntau ua lub luag haujlwmsnyob rau hauv dej tuav thiab thickening nyob rau hauv kev tsim kho kev lag luam thiab yog dav siv nyob rau hauvdrymix mortars, zoo li pobzeb nplaum, grouts, plastering, phab ntsa putty, tus kheej leveling, rwb thaiv tsev mortar thiab lwm yam.
Feem ntau, rau putty hmoov, lub viscosity ntawmHPMCyog txaus ntawm 70,000 mus rau 80,000. Lub ntsiab tseem ceeb yog nyob rau hauv nws cov dej tuav kev ua tau zoo, thaum lub thickening nyhuv yog me me. Rau mortar, cov kev xav tau rauHPMCyog siab dua, thiab cov viscosity yuav tsum nyob ib ncig ntawm 150,000, uas tuaj yeem xyuas kom meej tias nws ua haujlwm zoo dua hauv cov cement mortar. Tau kawg, nyob rau hauv cov hmoov putty, tsuav yog cov dej tuav kev ua tau zoo ntawm HPMC yog qhov zoo, txawm tias cov viscosity tsawg (70,000 txog 80,000), nws tau txais. Txawm li cas los xij, hauv cov cement mortar, nws yog qhov zoo dua los xaiv HPMC nrog cov viscosity loj dua (ntau dua 100,000), vim tias nws cov dej tuav tau ntau dua hauv qhov xwm txheej no.
Qhov teeb meem ntawm putty hmoov tshem tawm feem ntau yog nyob ntawm qhov zoo ntawm calcium hydroxide thiab muaj me ntsis ua rau HPMC. Yog tias cov ntsiab lus calcium ntawm calcium hydroxide tsawg lossis qhov piv ntawm CaO thiab Ca (OH) 2 tsis tsim nyog, nws yuav ua rau cov hmoov putty poob. Hais txog qhov cuam tshuam ntawm HPMC, nws yog qhov tseem ceeb ntawm nws cov dej tuav dej. Yog tias cov dej khaws cia ntawm HPMC tsis zoo, nws kuj tseem yuav muaj qee yam cuam tshuam rau depowdering ntawm putty hmoov.
Cov kev cai rau kev siv cov hmoov putty yog qhov tsawg. Ib qho viscosity ntawm 100,000 yog txaus. Qhov tseem ceeb yog kom muaj cov dej tuav tau zoo. Nyob rau hauv cov nqe lus ntawm mortar, qhov yuav tsum tau muaj kuj siab thiab siab viscosity yog yuav tsum tau, thiab 150,000 cov khoom muaj cov nyhuv zoo dua.
