Hydroxypropyl methylcellulose (HPMC)yog cov khoom siv tshuaj polymer uas nquag siv los ua lub luag haujlwm tseem ceeb hauv cov nplais pobzeb adhesives.
1. Lub luag haujlwm tseem ceeb ntawm hydroxypropyl methylcellulose
thickening nyhuv
HPMCua raws li lub thickener nyob rau hauv cov pobzeb kua nplaum, uas yuav ua rau kom lub viscosity thiab sib xws ntawm cov kua nplaum, ua kom nws smoother thiab yooj yim rau siv thaum lub sij hawm tsim kho. Cov yam ntxwv no pab tswj lub thickness ntawm txheej kom tsis txhob nyias dhau los yog tuab heev thiab txhim kho kev tsim kho.
Kev tuav dej
Lwm qhov tseem ceeb ntawm HPMC yog nws cov dej tuav tau zoo heev. Hauv cov pobzeb nplaum, HPMC tuaj yeem kaw cov dej noo thiab txuas ntxiv lub sijhawm hydration ntawm cov cement lossis lwm cov ntaub ntawv cementing. Qhov no tsis tsuas yog txhim kho lub zog sib txuas ntawm cov pobzeb nplaum, tab sis kuj tsis txhob tawg lossis tsis muaj zog sib txuas teeb meem tshwm sim los ntawm kev ya raws sai.
Txhim kho kev tsim kho kev ua haujlwm
HPMC muab cov nplais nplaum nplaum ua haujlwm zoo, suav nrog kev muaj zog sag tsis kam thiab lub sijhawm qhib ntev dua. Cov cuab yeej tiv thaiv sag ua rau cov kua nplaum tsis tshua muaj plam thaum siv rau ntawm qhov chaw ntsug; thaum txuas ntxiv lub sijhawm qhib ua rau cov neeg ua haujlwm tsim kho ntau lub sijhawm los kho qhov chaw ntawm cov vuas, txhim kho kev tsim kho kom zoo thiab muaj txiaj ntsig.
Tusyees dispersed
HPMC muaj solubility zoo thiab tuaj yeem tawg sai sai hauv dej los tsim cov tshuaj colloidal ruaj khov. Kev siv HPMC hauv pobzeb nplaum tuaj yeem ua rau cov khoom sib npaug sib npaug, yog li txhim kho tag nrho kev ua haujlwm ntawm cov kua nplaum.
2. Qhov zoo ntawm hydroxypropyl methylcellulose
Kev tiv thaiv ib puag ncig
HPMC yog cov khoom tsis muaj tshuaj lom, tsis muaj mob thiab ib puag ncig tus phooj ywg uas ua tau raws li cov khoom siv niaj hnub ntsuab ntsuab. Tsis muaj cov tshuaj phem yuav raug tsim thaum siv thiab siv, thiab nws yog tus phooj ywg zoo rau cov neeg ua haujlwm tsim kho thiab ib puag ncig.
Muaj zog tiv taus huab cua
HPMCtxhim kho huab cua tsis kam ntawm cov nplais pobzeb nplaum, ua rau nws ruaj khov nyob rau hauv qhov kub thiab txias, tsis tshua muaj kub los yog qhov chaw ntub dej, thiab tsis ua rau tsis ua haujlwm vim kev hloov ib puag ncig.
Tus nqi siab ua haujlwm
Txawm hais tias HPMC nws tus kheej yog kim dua, vim nws qhov ntau npaum li cas thiab cov txiaj ntsig tseem ceeb, nws muaj tus nqi siab tag nrho.
3. Daim ntawv thov ntawm hydroxypropyl methylcellulose nyob rau hauv ceramic pobzeb nplaum
HPMC yog dav siv nyob rau hauv cov pobzeb zoo tib yam adhesives thiab hloov cov pobzeb adhesives, nrog rau sab hauv tsev thiab sab nraum zoov phab ntsa vuas, pem teb vuas thiab cov vuas luaj ceramic. Tshwj xeeb:
Ordinary pobzeb tso
Nyob rau hauv cov tsoos me me ceramic pobzeb paving, qhov sib ntxiv ntawm HPMC tuaj yeem txhim kho qhov adhesion thiab tsis txhob hollowing lossis poob tawm.
Cov vuas loj loj lossis hnyav pob zeb paving
Txij li cov vuas luaj ceramic loj loj muaj qhov hnyav hnyav, kev txhim kho kev ua haujlwm zoo ntawm HPMC tuaj yeem ua kom ntseeg tau tias cov vuas ceramic tsis yooj yim txav thaum lub sijhawm paving, yog li txhim kho kev tsim kho kom zoo.
Pem teb cua sov pobzeb tso
Cov cua sov hauv pem teb ib puag ncig muaj kev xav tau siab ntawm kev sib khi lub zog thiab kev ua kom yooj yim ntawm cov kua nplaum. HPMC cov dej tuav thiab txhim kho cov khoom sib txuas yog qhov tseem ceeb tshwj xeeb, thiab nws tuaj yeem hloov kho tau zoo rau cov teebmeem ntawm thermal expansion thiab contraction.
waterproof pobzeb nplaum
Hauv cov chaw ntub dej xws li chav dej thiab chav ua noj, HPMC cov dej tsis kam thiab cov khoom tuav dej tuaj yeem txuas ntxiv lub neej kev pab cuam ntawm cov nplais nplaum.
4. Tej yam yuav tsum nco ntsoov
Kev tswj noj tshuaj
Kev siv HPMC ntau dhau tuaj yeem ua rau muaj viscosity ntau dhau thiab cuam tshuam rau kev tsim kho kom zoo; Kev siv tsawg dhau yuav cuam tshuam rau kev tuav dej thiab kev sib txuas ntawm lub zog. Nws yuav tsum tau kho kom haum raws li cov qauv tshwj xeeb.
Synergy nrog lwm yam additives
HPMC feem ntau yog siv rau hauv cov nplais pobzeb nplaum nrog lwm cov khoom ntxiv xws li cov hmoov latex thiab dej txo tus neeg sawv cev kom ua tiav cov txiaj ntsig zoo dua.
ib puag ncig adaptability
Qhov kub thiab av noo ntawm ib puag ncig kev tsim kho yuav cuam tshuam rau kev ua haujlwm ntawm HPMC, thiab cov qauv khoom tsim nyog yuav tsum raug xaiv raws li kev tsim kho tshwj xeeb.
Hydroxypropyl methylcellulose (HPMC)muaj ntau lub luag haujlwm hauv cov nplais nplaum, xws li thickening, dej tuav, txhim kho kev tsim kho thiab kev ua kom tsis sib haum. Nws yog ib qho tseem ceeb ntawm cov khoom siv los txhim kho kev ua haujlwm ntawm cov nplais nplaum. Los ntawm kev siv lub ntsiab lus ntawm HPMC, qhov adhesion, huab cua tsis kam thiab kev tsim kho yooj yim ntawm cov nplais pobzeb nplaum tuaj yeem txhim kho kom tau raws li qhov kev thov rau cov khoom zoo hauv cov tsev niaj hnub. Hauv kev siv cov tswv yim, nws yog ib qho tsim nyog los muab cov qauv kev cai thiab kev tsim kho ib puag ncig nrog kev xaiv kev tshawb fawb thiab kev sib txuam los muab kev ua si tag nrho rau nws qhov zoo.
