Ka lebaka la lintlha tse kang mocheso oa moea, mongobo, khatello ea moea le lebelo la moea, sekhahla sa ho fetoha ha mongobo lihlahisoa tse thehiloeng ho gypsum se tla ameha.
Kahoo hore na e ka har'a seretse sa gypsum-based leveling, caulk, putty, kapa gypsum-based self-leveling, hydroxypropyl methylcellulose ether (HPMC) e bapala karolo ea bohlokoa.
Ho boloka metsi a BAOSHUIXINGHPMC
Molemo ka ho fetisisa hydroxypropyl methylcellulose (HPMC) e ka rarolla bothata ba ho boloka metsi tlas'a mocheso o phahameng.
Lihlopha tsa eona tsa methoxy le hydroxypropoxy li ajoa ka mokhoa o lekanang hammoho le ketane ea molek'hule ea cellulose, e ka ntlafatsang bokhoni ba liathomo tsa oksijene holim'a li-bond tsa hydroxyl le ether ho kopana le metsi ho etsa li-hydrogen bond, ho etsa hore metsi a sa lefelloeng a be metsi a tlamiloeng, ka tsela eo ho laola ka katleho ho fetoha mouoane. ya metsi a bakoang ke mocheso o phahameng wa lehodimo bakeng sa ho boloka metsi a mangata.
Constructability ea SHIGONGXINGHPMC
Lihlahisoa tse khethiloeng ka nepo tsa cellulose ether li ka kenella ka potlako lihlahisoa tse fapaneng tsa gypsum ntle le agglomeration, 'me ha li na tšusumetso e mpe ho porosity ea lihlahisoa tsa gypsum tse phekotsoeng, kahoo li netefatsa ts'ebetso ea phefumoloho ea lihlahisoa tsa gypsum.
E na le phello e itseng ea ho khutlisa empa ha e ame kholo ea likristale tsa gypsum; e etsa bonnete ba bokhoni ba ho tlama ha thepa ho ea holim'a setsi ka ho khomarela metsi ka mokhoa o loketseng, ho ntlafatsa haholo ts'ebetso ea kaho ea lihlahisoa tsa gypsum, 'me ho bonolo ho jala ntle le lisebelisoa tsa ho khomarela.
Lubricity ea RUNHUAXINGHPMC
Hydroxypropyl methylcellulose ea boleng bo holimo e ka qhalakanngoa ka mokhoa o ts'oanang le ka katleho ka seretse sa samente le lihlahisoa tse thehiloeng ho gypsum, 'me ea phuthela likaroloana tsohle tse tiileng,' me ea etsa filimi ea ho kolobisa, 'me mongobo o botlaaseng o tla qhibiliha butle-butle ka nako e telele. ho lokolla, le ho etsa karabelo ea hydration ka lisebelisoa tsa inorganic gelling, ka hona ho netefatsa matla a tlamahano le matla a hatellang a thepa.
