HPMC tuaj yeem txhim kho kev ua haujlwm ua haujlwm ntawm kev siv cov nplaum, suav nrog fellity, tsim kho thiab flatening. Cov nyhuv nws lubricating ua rau cov nplaum kom yooj yim rau kev siv thiab txhuam thaum lub sijhawm kev tsim kho, txhim kho kev ua haujlwm zoo thiab ua kom muaj cov nyhuv siv zaum kawg.
4. Txhim Kho Lub Zog Bonding
HPMC tuaj yeem txhim kho cov nplaum ntawm cov nplaum thiab txhim kho lub zog ntawm kev sib raug zoo ntawm cov nplaum los ntawm kev tsim cov khaub ncaws hnav thiab cov txheej txheem sib raug zoo. Qhov no yog qhov tseem ceeb heev rau kev ruaj ntseg ntawm lub tsev tsim xws li phab ntsa thiab cov tsev sib xyaw, thiab tuaj yeem tiv thaiv cov vuas luaj, thiab lwm yam los ntawm kev poob tawm.
5. Anti-plam kev ua haujlwm
Hauv cov ntawv thov xws li pobzeb cov nplaum, HPMC tuaj yeem txhim kho cov khoom siv los tiv thaiv kev muaj peev xwm. Qhov no yuav pab kom cov vuas tsau rau ntawm cov chaw tsim khoom ntsug, txo cov zaus ntawm kev kho kom haum thiab ua haujlwm, thiab yog li txhim kho cov khoom siv zoo.
(3) Cov ntawv thov tshwj xeeb ntawm HPMC nyob rau hauv lub tsev sib txawv
1. Pobzeb Adhesive
Nyob rau hauv cov nplais nplaum, HPMC tsis tsuas yog ua lub luag haujlwm ntawm thickening thiab khaws cia cov dej ntws los ntawm cov nplais nplaum, kom muaj kev ruaj ntseg ntawm cov vuas thaum kev tsim kho. Nws cov khoom sib txawv tshwj xeeb ua kom cov nplaum kom muaj viscosity nyob hauv nyob rau hauv cov neeg tsim kev tsim kho, ua rau nws yooj yim kho thiab txua.
2. Phab Ntsa Putty
HPMC feem ntau yog lub luag haujlwm hauv kev khaws dej thiab ua kom tuab hauv phab ntsa putty, ua kom lub zog ua haujlwm ntau dua thiab muaj qhov chaw du tom qab ziab. Nws cov dej khaws cia yuav txo cov txheej tawg thiab shrinkage ntawm txheej putty thaum kev tsim kho, thiab txhim kho qhov zoo ntawm cov txheej kawg.
3. Kaub Qhuav
Hauv cov cug qhuav, txoj haujlwm tseem ceeb ntawm HPMC yog khaws cov dej noo thiab tiv thaiv thaum ntxov dej poob, yog txhim kho cov haujlwm ua haujlwm thiab cov nplaum ntawm lub tshuaj khib. Nws tseem tuaj yeem hloov kho lub culture ntawm cult ua nws haum rau cov kev siv sib txawv, xws li Masonry Collhu, muab tshuaj khib, thiab lwm yam.
4. Lub Tsev Sealant
HPMC tsuas yog siv nyob rau hauv kev tsim cov tuam txhab txhim kho kom zoo nkauj thiab ua haujlwm ntawm cov pob qij txha thaum siv thiab tswj cov khoom zoo. Nws cov dej khaws cia kuj tseem tuaj yeem tiv thaiv kev sib txuas ntawm kev poob dej sai dhau thiab txhim kho cov khoom tsim tau zoo.
(4) Qhov zoo ntawm HPMC hauv cov nplaum txhim kho
Kev tiv thaiv ib puag ncig: HPMC yog muab tau los ntawm cov khoom siv cellulose ntuj, tsis tau tso cov tshuaj muaj kev phom sij, thiab ua phooj ywg rau ib puag ncig thiab tib neeg lub cev.
Stability: HPMC muaj cov tshuaj ruaj khov zoo thiab tsis yooj yim cuam tshuam los ntawm ib puag ncig cov khoom xws li kub thiab pH, thiab tuaj yeem tswj nws qhov kev ua tau ntev.
Kev sib xyaw: HPMC tau sib xyaw nrog ntau yam khoom siv hauv tsev thiab tuaj yeem ua ke nrog cov khoom siv xws li cement, thiab kev sib xyaws rau kev siv dej ua haujlwm.
(5) cov qauv kev loj hlob yav tom ntej
Nrog rau kev txhim kho kev tsim kho kev siv thev naus laus zis, kev thov cov kev cia siab ntawm HPMC hauv cov nplaum ua lag luam yog qhov dav. Cov lus qhia txog yav tom ntej muaj xws li:
Kev ua haujlwm zoo: Txhim kho cov versatility ntawm HPMC los ntawm kev hloov kho tshuaj lom neeg lossis sib txuas nrog lwm cov kev ntxiv ntxiv kom tau raws li cov kev xav tau ntawm cov kev siv khoom siv sib txawv.
Cov khoom lag luam ib puag ncig cov khoom lag luam: tsim cov khoom lag luam HPMC kom txo tau qhov kev cuam tshuam rau ib puag ncig.
Cov ntaub ntawv ntse: Tshawb cov ntaub ntawv ntawm HPMC hauv cov ntaub ntawv ua kom zoo, cov khoom siv kub, thiab lwm yam.
Instant HydroxyPropyyl methylcellulose, raws li ib qho tseem ceeb ntxiv rau kev txhim kho lub viscosity, kev siv dej, thiab tsim cov khoom nplaum ntawm cov nplaum. Nws daim ntawv thov hauv cov nplais nplaum, phab ntsa putty thiab muab cov liaj teb tau txhim kho kev tsim kho zoo thiab ua tau zoo. Nyob rau yav tom ntej, los ntawm kev hloov kho thev naus laus zis txuas ntxiv thiab kev txhim kho ntawm HPMC hauv cov nplaum txhim kho yuav pab txhawb nqa qhov chaw dav dav.
