Hobaneng ha Cellulose (HPMC) e le Karolo ea Bohlokoa ea Gypsum

Cellulose, ka mokhoa oaHydroxypropyl Methylcellulose (HPMC), e bapala karolo ea bohlokoa ho thepa e thehiloeng ho gypsum, e tlatsetsang ts'ebetsong le ts'ebetsong ea bona lits'ebetsong tse fapaneng. Ho tloha kahong ho isa ho tsa meriana, lihlahisoa tsa gypsum tse ntlafalitsoeng ke HPMC li fana ka mefuta e mengata ea melemo, e e etsa karolo ea bohlokoahali.

1. Ts'ebetso e Ntlafetseng le Ho ata:
HPMC e sebetsa joalo ka mofetoleli oa rheology lihlahisoa tse thehiloeng ho gypsum, e ntlafatsang ts'ebetso ea tsona le ho ata. E thusa ho boloka botsitso bo lakatsehang ba motsoako oa gypsum, e lumellang ts'ebeliso e bonolo le liphetho tse boreleli tsa bokaholimo. Sena se bohlokoa ka ho khetheha lits'ebetsong tsa kaho moo gypsum plaster kapa seretse se hlokang ho sebelisoa ka mokhoa o ts'oanang le hantle.

2. Paballo ea Metsi:
E 'ngoe ea mesebetsi ea bohlokoa ea HPMC mefuteng ea gypsum ke bokhoni ba eona ba ho boloka metsi. Ka ho etsa filimi holim'a likaroloana tsa gypsum, HPMC e liehisa mouoane oa metsi nakong ea ts'ebetso ea ho beha. hydration ena ea nako e telele e thusa ho folisa hantle ha gypsum, e lebisang ntlafatsong ea matla le ho fokotsa ho phatloha.

3. Matlafatso e Matlafalitsoeng:
Lintho tse tsoang ho cellulose joalo ka HPMC li kenya letsoho molemong oa ho khomarela lisebelisoa tse thehiloeng ho gypsum. Li thusa ho kopanya likaroloana tsa gypsum hammoho le ho li khomarela likarolong tse fapaneng tse kang lehong, konkreite kapa li-drywall. Sena se tiisa matla a maqhama a betere mme se fokotsa kotsi ea delamination kapa detachment ka nako.

4. Crack Resistance:
Ho kenyelletsoa ha HPMC mefuteng ea gypsum ho ntlafatsa ho hanyetsa ha bona ho phunyeha. Ka ho khothaletsa hydration e ts'oanang le ho fokotsa shrinkage nakong ea ho omisa, HPMC e thusa ho fokotsa sebopeho sa mapetsong a sehlahisoa se felileng. Sena se molemo ka ho khetheha lits'ebetsong tse kang gypsum plasters le metsoako e kopantsoeng, moo libaka tse se nang mapheo li leng bohlokoa bakeng sa mabaka a botle le moralo.

5. Nako ea Tlhophiso e Laolehileng:
HPMC e lumella ho lokisoa ha nako ea ho beha lisebelisoa tse thehiloeng ho gypsum ho latela litlhoko tse itseng. Ka ho laola sekhahla sa hydration le gypsum crystallization, HPMC e ka lelefatsa kapa ea potlakisa ts'ebetso ea ho beha ha ho hlokahala. Ho feto-fetoha ha maemo hona ho molemo lits'ebetsong tse fapaneng, ho tloha ho tsa kaho ho isa ho tsa meriana, moo ho leng bohlokoa ho beha nako e nepahetseng.

6. Thepa e Ntlafetseng ea Mechini:
Ho kenyelletsa HPMC mefuteng ea gypsum ho ka ntlafatsa thepa ea bona ea mochini, ho kenyelletsa le matla a hatellang, matla a flexural, le ho hanyetsa tšusumetso. Ka ho ntlafatsa kabo ea metsi ka har'a matrix a gypsum le ho khothaletsa hydration e nepahetseng, HPMC e kenya letsoho ho nts'etsopele ea thepa e teteaneng le e tšoarellang haholoanyane.

7. Ho fokotsa Lerōle:
Lisebelisoa tse thehiloeng ho Gypsum tse nang le HPMC li bonts'a lerōle le fokotsehileng nakong ea ts'ebetso le ts'ebeliso. Sehlahisoa sa cellulose se thusa ho kopanya likaroloana tsa gypsum, ho fokotsa tlhahiso ea lerōle le tsoang moeeng. Sena ha se ntlafatse feela sebaka sa ho sebetsa empa hape se ntlafatsa bohloeki ka kakaretso ba sebaka sa kopo.

8. Ho lumellana le Li-additives:
HPMC e lumellana le mefuta e mengata ea li-additives tse atisang ho sebelisoa ha ho etsoa gypsum formulations, tse kang li-air entrainers, li-plasticizers, le li-accelerator tsa ho seta. Tšebelisano ena e lumella baetsi ba lihlahisoa ho hlophisa thepa e thehiloeng ho gypsum ho fihlela litlhoko tse khethehileng tsa ts'ebetso, tse kang ho feto-fetoha ha maemo, ho fokotseha ha tlhokahalo ea metsi, kapa linako tse behiloeng ka potlako.

Hydroxypropyl Methylcellulose (HPMC)e na le likarolo tse ngata tsa thepa e thehiloeng ho gypsum, e fanang ka melemo e mengata lits'ebetsong tse fapaneng. Ho tloha ho ntlafatsa bokhoni ba ho sebetsa le ho khomarela ho ntlafatsa khanyetso ea crack le thepa ea mochine, HPMC e kenya letsoho haholo ts'ebetsong, ho tšoarella, le ho feto-fetoha ha lihlahisoa tsa gypsum. Bokhoni ba eona ba ho laola ho boloka metsi, ho beha nako, le ho tsamaellana le li-additives le ho feta ho hatisa bohlokoa ba eona e le karolo ea bohlokoa mekhoeng ea sejoale-joale ea gypsum. Ha liindasteri li ntse li tsoela pele ho ntlafatsa le ho fetoha, tlhokahalo ea lisebelisoa tsa gypsum tse sebetsang hantle tse matlafalitsoeng ka HPMC e lebelletsoe ho hola, ho tsamaisa lipatlisiso le nts'etsopele lebaleng lena.
