Cellulose ethers feem ntau yog siv rau hauv daim ntawv thov skim tsho vim lawv lub peev xwm los txhim kho kev ua haujlwm, adhesion, thiab tag nrho kev ua tau zoo ntawm skim coat mixs. Ntawm no yog yuav ua li cas cellulose ethers siv nyob rau hauv skim daim ntaub ntawv:

1. Kev tuav dej: Cellulose ethers, xws li methylcellulose (MC) lossis hydroxypropyl methylcellulose (HPMC), ua raws li cov dej khaws cia hauv cov khoom sib xyaw ua ke. Lawv nqus thiab tuav dej hauv lub tsho skim, tiv thaiv kom qhuav ntxov ntxov thiab txhim kho kev ua haujlwm ntawm kev sib tov.
2. Txhim kho kev ua haujlwm: Los ntawm kev ua kom cov dej khaws cia ntawm skim coat mixs, cellulose ethers txhim khu kev ua haujlwm thiab yooj yim ntawm daim ntawv thov. Skim coats uas muaj cellulose ethers muaj ib tug smoother sib xws thiab yog yooj yim dua kis tau tus mob, txo cov kev siv zog yuav tsum tau rau daim ntawv thov thiab ua kom tiav ib tug ntau uniform tiav.
3. Txo Shrinkage: Cellulose ethers pab txo qis shrinkage hauv skim tsho sib tov thaum ziab thiab kho. Qhov no minimizes qhov tsim ntawm cov kab nrib pleb thiab nto irregularities, uas ua rau ib tug smoother thiab ntau aesthetically pleasing finish.
4. Enhanced Adhesion: Cellulose ethers txhim kho cov adhesion ntawm skim tsho rau ntau yam substrates, nrog rau cov phab ntsa qhuav, plaster, pob zeb, thiab masonry. Lawv txhawb kev sib raug zoo ntawm cov skim tsho thiab cov substrate, txo cov kev pheej hmoo ntawm delamination los yog ua tsis tau raws sij hawm.
5. Lub Sijhawm Qhib Ntxiv: Cellulose ethers txuas ntxiv lub sijhawm qhib ntawm skim tsho sib xyaw, tso cai rau lub sijhawm ua haujlwm ntev ua ntej lub tsho tiv no skim pib. Qhov no yog qhov tshwj xeeb tshaj yog nyob rau hauv daim ntawv thov skim tsho uas txuas ntxiv qhib lub sij hawm yuav tsum tau ua kom tiav ib tug du thiab theem nto.
6. Sag Resistance: Cellulose ethers pab tswj lub rheology ntawm skim coat mixs, txo sagging los yog slumping thaum ntsug los yog overhead daim ntaub ntawv. Qhov no ua kom lub tsho skim adheres zoo rau qhov chaw ntsug yam tsis muaj kev zawv zawg ntau dhau los yog poob, ua rau muaj kev txhim kho kev sib raug zoo thiab txo cov khoom pov tseg.
7. Customizable Properties: Cellulose ethers muab kev yooj yim hauv skim coat formulation, tso cai rau cov tuam txhab tsim cov khoom skim coat rau cov ntawv thov tshwj xeeb. Los ntawm kev kho hom thiab ntau npaum li cas ntawm cellulose ethers siv, skim coat yam ntxwv xws li teem sij hawm, lub zog, thiab dej tuav yuav optimized rau txawv substrates thiab tej yam kev mob.

Zuag qhia tag nrho, cellulose ethers ua lub luag haujlwm tseem ceeb hauv kev siv lub tsho tiv no los ntawm kev txhim kho kev ua haujlwm, adhesion, durability, thiab kev ua haujlwm. Lawv cov khoom siv ntau yam ua rau lawv muaj txiaj ntsig zoo ntxiv hauv cov txheej txheem skim tsho, pab kom ua tiav du, qib, thiab ua kom zoo nkauj ua tiav ntawm ntau yam substrates.
