Kodi kukhuthala koyenera kwambiri kwa hydroxypropyl methylcellulose ndi chiyani

Hydroxypropyl methylcellulose nthawi zambiri amagwiritsidwa ntchito mu putty powder yokhala ndi mamasukidwe a 100,000, pomwe matope amakhala ndi zofunikira zowoneka bwino, motero ziyenera kugwiritsidwa ntchito ndi mamasukidwe 150,000. Ntchito yofunika kwambiri ya hydroxypropyl methylcellulose ndikusunga madzi, ndikutsatiridwa ndi makulidwe. Choncho, mu ufa wa putty, malinga ngati kusungirako madzi kumatheka, kukhuthala kumakhala kochepa. Nthawi zambiri, mamasukidwe akayendedwe akamakulirakulira, m'pamenenso amasunga madzi bwino, koma mamasukidwe akayendedwe akapitilira 100,000, kukhuthala kwake sikukhudza kusungidwa kwa madzi.

Malinga ndi mamasukidwe akayendedwe, hydroxypropyl methylcellulose nthawi zambiri amagawidwa m'mitundu iyi:

1. Low mamasukidwe akayendedwe: 400 mamasukidwe akayendedwe mapadi mapadi, makamaka ntchito kudziletsa-leveling matope.
Ili ndi mamasukidwe otsika komanso madzi abwino. Pambuyo powonjezerapo, idzayendetsa kusungirako madzi pamtunda, kutuluka kwa magazi sikukuwonekera, kuchepa kumakhala kochepa, kung'ambika kumachepetsedwa, komanso kungathe kukana kusungunuka ndi kupititsa patsogolo madzi ndi pompopompo.

2. Kukhuthala kwapakatikati ndi kochepa: 20,000-50,000 viscosity cellulose, yomwe imagwiritsidwa ntchito kwambiri muzinthu za gypsum ndi caulking agents.
Kukhuthala kochepa, kusunga madzi ambiri, kugwira ntchito bwino, kuonjezedwa kwamadzi pang'ono,

3. Kukhuthala kwapakatikati: 75,000-100,000 viscosity cellulose, yomwe imagwiritsidwa ntchito makamaka mkati ndi kunja kwa khoma putty.
Kukhuthala pang'ono, kusungirako madzi kwabwino, kumanga kwabwino komanso kuwongoka

4. High mamasukidwe akayendedwe: 150,000-200,000, makamaka ntchito polystyrene tinthu kutchinjiriza matope mphira ufa, vitrified microbead kutchinjiriza matope
Ndi ma viscosity apamwamba komanso kusungirako madzi ambiri, matope siwosavuta kuponya phulusa ndi kugwa, zomwe zimapangitsa kuti zomangamanga zikhale bwino.

Nthawi zambiri, kukweza kwa mamasukidwe apamwamba, kusungika bwino kwa madzi, kotero makasitomala ambiri amasankha kugwiritsa ntchito mapadi apakati-makamakamakamaka (75,000-100,000) m'malo mwa sing'anga-otsika mamasukidwe apamwamba a cellulose (20,000-50,000) kuti achepetse kuchuluka kwake, ndiyeno mtengo wowongolera
