• Kev ua haujlwm: Hemc txhim kho lub zog ntawm cov tsho tiv no skim, ua rau nws yooj yim dua mus kis, du, thiab siv ntawm cov chaw.
• Adhesive lub zog: ntxiv ntawm HEMC tuaj yeem txhim kho cov nplaum muaj zog ntawm lub tsho tiv no skim, txhawb nqa zoo dua rau cov txheej txheem.
• LAG LUAM: HEMC pab txhawb rau lub tsho tiv no sib xws, tiv thaiv cov teeb meem xws li sagging thiab ua kom tiav cov ntawv thov tsis zoo.

2. Kev ua haujlwm ntawm Hydroxyethyl methyl methyl cellulose hauv Skim tsho tiv no

2.1 Cov dej ua ke

HEMC yog hydrophilic polymer, lub ntsiab lus nws muaj kev muaj zog muaj zog rau dej. Nyob rau hauv skim lub tsho tiv no ua yeeb yam, nws ua raws li cov dej tswj kav dej, kom ua kom cov dej sib xyaw ua haujlwm tau ua haujlwm ntev. Qhov no yog qhov tshwj xeeb tshaj yog nyob rau hauv skim tsho tiv no cov ntawv thov uas qhib lub sij hawm lub sij hawm ntev yog xav tau.

2.2 Txhim kho kev ua haujlwm

HEMC txhim kho cov haujlwm ntawm lub tsho tiv no skim los ntawm kev muab txoj kev du thiab creamy sib xws. Qhov kev ua haujlwm no txhim kho pub rau qhov yooj yim kis thiab thov rau ntau qhov chaw, ua kom tiav thiab ua kom zoo dua qub.

2.3 txuj ci muaj zog

HEMC pab txhawb rau cov nplaum muaj zog ntawm lub tsho tiv no skim, txhawb kom zoo dua kev sib koom tes ntawm lub tsho tiv no txheej thiab txheej. Qhov no yog qhov tseem ceeb rau kev ua tiav lub sijhawm ruaj khov thiab ntev ntev ntawm phab ntsa lossis qab nthab.

2.4 Sag Kuj

Lub zog rheological ntawm HEMC pab nyob rau hauv kev tiv thaiv sagging lossis slumping ntawm lub tsho tiv no thaum daim ntawv thov. Qhov no yog qhov tseem ceeb rau kev ua tiav cov tuab tuab thiab tsis txhob ua qhov chaw tsis ncaj ncees.

3. Cov ntawv thov hauv Skim tsho tiv no

3.1 Sab hauv phab ntsa tau tiav

HEMC yog feem ntau siv nyob rau hauv skim lub tsho loj tsim rau sab hauv phab ntsa xov. Nws pab kom ua tiav txoj kev du thiab niaj hnub, npaj txhij rau kev pleev xim lossis lwm yam kev kho kom zoo nkauj.

3.2 Kho thiab muab cov tebchaw

Hauv kev kho thiab patching tebchaw, hemc txhim kho cov haujlwm thiab cov nplaum ntawm cov khoom siv, ua kom zoo rau kev kho kom yooj yim thiab tawg rau ntawm phab ntsa thiab nthab.

3.3 Kev dai kom zoo nkauj tiav

Rau kev ua kom zoo nkauj tiav, xws li textured lossis qauv ua haujlwm, hemcs hauv kev tswj kom muaj nuj nqis thiab ua haujlwm, pub rau kev tsim muaj ntau yam kev ua kom zoo nkauj.

4. Kev txiav txim siab thiab ceev faj

4.1 DOSAGE THIAB KEV LAWV

Qhov ntau npaum ntawm HEMC nyob rau hauv skim lub tsho tiv no yuav tsum tau ua tib zoo tswj kom ua tiav cov khoom uas xav tau yam tsis muaj kev cuam tshuam rau lwm tus yam ntxwv. Compatibility nrog lwm cov khoom ntxiv thiab cov ntaub ntawv kuj tseem ceeb heev.

4.2 Kev cuam tshuam ib puag ncig

Kev txiav txim siab yuav tsum tau muab rau ib puag ncig kev cuam tshuam ntawm kev tsim cov khoom siv ntxiv, suav nrog HEMC. Kev siv ceev thiab hauv eco-phooj ywg zoo yog qhov tseem ceeb ntxiv hauv kev tsim kho thiab cov ntaub ntawv kev lag luam hauv tsev.

4.3 Cov Lus Qhia Khoom Muag Khoom

HEMC cov khoom yuav sib txawv hauv cov lus qhia tshwj xeeb, thiab nws yog qhov tseem ceeb kom xaiv cov qib tsim nyog raws li cov kev xav tau ntawm daim ntawv thov tsho tshwj xeeb.

5. Xaus

Nyob rau hauv cov ntsiab lus ntawm skim tsho tiv no, Hydroxyethy cellulose yog ib qho tseem ceeb ntxiv uas ua rau cov dej ua haujlwm, ua haujlwm, ua kom muaj zog, thiab muaj zog. Skim coats tsim nrog HEMC muab ib tug du, ruaj, thiab ua kom zoo nkauj ua tiav rau sab hauv phab ntsa thiab qab nthab. Ua tib zoo xav txog kev siv tshuaj, kev sib raug zoo, thiab ib puag ncig nws cov txiaj ntsig zoo rau nws cov txiaj ntsig sib txawv hauv kev sib tw npog tsho sib txawv.
