☑ Kev khaws cia thiab kev xa khoom
Yuav tsum khaws cia thiab xa tuaj rau hauv qhov chaw qhuav thiab huv si hauv nws lub pob thawj thiab kom deb ntawm qhov kub. Tom qab qhib lub pob rau kev tsim khoom, yuav tsum kaw kom nruj kom tsis txhob muaj dej noo nkag.
Pob: 25kg/hnab, ntau txheej ntawv yas sib xyaw hnab nrog lub qhov rooj qhib plaub fab hauv qab, nrog lub hnab yas polyethylene sab hauv.
☑Lub neej txee
Lub sijhawm lav yog ob xyoos. Siv nws sai li sai tau thaum muaj qhov kub thiab txias siab thiab av noo, kom tsis txhob ua rau muaj kev sib xyaw ua ke.
☑Kev nyab xeeb ntawm cov khoom
Hydroxypropyl methyl cellulose HPMC LK10M tsis yog cov khoom phom sij. Cov ntaub ntawv ntxiv txog kev nyab xeeb tau muab tso rau hauv Daim Ntawv Qhia Txog Kev Nyab Xeeb Khoom Siv.
Cov Lus Nug Feem Ntau
Hydroxypropyl methylcellulose (HPMC) yog cov cellulose ethers uas muaj cov pab pawg hydroxyl ntawm cov saw cellulose hloov rau pab pawg methoxy lossis hydroxypropyl.It yog ua los ntawm kev sib xyaw tshwj xeeb ntawm cov paj rwb cellulose ntshiab heev nyob rau hauv alkaline tej yam kev mob. Nyob rau hauv xyoo tas los no, HPMC, ua ib qho kev sib xyaw ua haujlwm, feem ntau ua lub luag haujlwmshauv kev khaws dej thiab thickening hauv kev lag luam kev tsim kho thiab siv dav hauvcov tshuaj khib nyiab qhuav, zoo li cov nplaum pobzeb, cov grouts, plastering, phab ntsa putty, tus kheej leveling, cov tshuaj khib nyiab rwb thaiv tsev thiab lwm yam.
Feem ntau, rau cov hmoov putty, qhov viscosity ntawmHPMCtxaus ntawm li ntawm 70,000 txog 80,000. Lub ntsiab lus tseem ceeb yog nws qhov kev ua tau zoo ntawm kev khaws dej, thaum qhov cuam tshuam ntawm kev tuab yog qhov me me. Rau cov mortar, qhov yuav tsum tau ua rauHPMCyog siab dua, thiab qhov viscosity yuav tsum nyob ib puag ncig 150,000, uas tuaj yeem ua kom nws ua haujlwm zoo dua hauv cov cement mortar. Tau kawg, hauv cov hmoov putty, tsuav yog qhov kev ua tau zoo ntawm HPMC zoo, txawm tias qhov viscosity qis (70,000 txog 80,000), nws yog qhov txais tau. Txawm li cas los xij, hauv cov cement mortar, nws yog qhov zoo dua los xaiv HPMC nrog viscosity loj dua (ntau dua 100,000), vim tias nws cov dej khaws cia tseem ceeb dua hauv qhov xwm txheej no.
Qhov teeb meem ntawm kev tshem tawm cov hmoov putty feem ntau nyob ntawm qhov zoo ntawm calcium hydroxide thiab tsis muaj feem cuam tshuam nrog HPMC. Yog tias cov calcium hydroxide hauv 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 feem ntau pom hauv nws cov dej tuav. Yog tias HPMC tsis muaj dej tuav, nws kuj tseem yuav muaj qee qhov cuam tshuam rau kev tshem cov hmoov putty.
Cov kev cai rau kev siv cov hmoov putty yog qhov tsawg heev. Qhov viscosity ntawm 100,000 txaus. Qhov tseem ceeb yog kom muaj cov khoom khaws cia dej zoo. Hais txog cov mortar, qhov yuav tsum tau ua yog siab heev thiab xav tau viscosity siab dua, thiab cov khoom 150,000 muaj txiaj ntsig zoo dua.
