Motsoako o kopaneng oa Gypsum, o tsejoang hape e le seretse sa drywall kapa motsoako o kopaneng feela, ke thepa ea kaho e sebelisoang ho aha le ho lokisa li-drywall. Haholo-holo e entsoe ka phofo ea gypsum, mineral e bonolo ea sulfate e kopantsoeng le metsi ho etsa setlolo. Sekhomaretsi sena se sebelisoa ho seam, lihuku le likheo lipakeng tsa li-drywall panels ho etsa sebaka se boreleli, se se nang moroallo.
Hydroxypropyl methylcellulose (HPMC) ke cellulose ether e atisang ho eketsoa ho lisebelisuoa tse kopantsoeng tsa samente ka mabaka a sa tšoaneng. HPMC e tsoa ho cellulose, polima ea tlhaho e fumanehang maboteng a lisele tsa semela. Mona ke lintlha tsa bohlokoa tsa ho sebelisa HPMC ka har'a komporo e kopaneng ea samente:
Poloko ea Metsi: HPMC e tsebahala ka thepa ea eona e ntle ea ho boloka metsi. Ha e kenyelelitsoe ho samente motsoako oa motsoako, e thusa ho thibela motsoako ho omella ka potlako. Nako e atolositsoeng ea ho sebetsa e etsa hore ho be bonolo ho sebelisa le ho qeta thepa e kopanetsoeng.
Ts'ebetso e ntlafalitsoeng: Keketso ea HPMC e ntlafatsa ts'ebetso ea motsoako o kopaneng. E fana ka botsitso bo bonolo, ho etsa hore ho be bonolo ho e sebelisa le ho sebetsa libakeng tsa drywall. Sena se bohlokoa haholo bakeng sa ho fumana liphetho tse shebahalang eka ke tsa setsebi.
Ho khomarela: HPMC e thusa motsoako o kopanetsoeng hore o khomarele holim'a drywall. E thusa motsoako hore o khomarele ka thata ho seams le manonyeletso, ho netefatsa tlamahano e matla le ea nako e telele hang ha thepa e omella.
Fokotsa ho fokotseha: Lisebelisoa tse kopantsoeng tsa Gypsum li atisa ho fokotseha ha li omella. Ho eketsoa ha HPMC ho thusa ho fokotsa ho honyela le ho fokotsa monyetla oa hore mapetsong a hlahe sebakeng se felileng. Sena se bohlokoa ho fumana liphetho tse phethahetseng le tse tšoarellang nako e telele.
Moemeli oa ho Koetlisa Moea: HPMC e boetse e sebetsa e le moemeli oa ho koetlisa moea. Sena se bolela hore e thusa ho kenyelletsa li-bubble tsa moea tse nyane ka har'a thepa ea seam, ho ntlafatsa ts'ebetso ea eona ka kakaretso le ho tšoarella.
Taolo e tsitsitseng: HPMC e fana ka taolo e kholo holim'a ho lumellana ha motsoako o kopanetsoeng. Sena se thusa ho fihlela sebopeho le botenya bo lakatsehang nakong ea kopo.
Ho bohlokoa ho hlokomela hore sebopeho se ikhethileng sa lisebelisoa tse kopaneng tsa gypsum se ka fapana ho tloha ho moetsi ho ea ho moetsi, mme limaraka tse fapaneng tsa HPMC li ka sebelisoa ho latela thepa e lakatsehang ea sehlahisoa sa ho qetela. Ho feta moo, li-additives tse ling tse kang li-thickeners, binders le retarders li ka kenyelletsoa molemong oa ho ntlafatsa ts'ebetso.
Hydroxypropyl methylcellulose (HPMC) cellulose ether e bapala karolo ea bohlokoa ho ntlafatseng ho sebetsa, ho khomarela le ho sebetsa ka kakaretso ha metsoako ea motsoako oa gypsum e sebelisoang kahong le ho lokisoa ha li-drywall. Thepa ea eona e feto-fetohang e thusa ho fihlela pheletso e boreleli le e tšoarellang holim'a li-drywall.
