Cellulose Ether HPMC Kaho Kereiti bakeng sa Wall Putties

Cellulose ether HPMC (Hydroxypropylmethylcellulose) hangata e sebelisoa e le tlatsetso ea bohlokoa mekhoeng ea li-putty tsa lebota. Wall putty ke thepa ea samente e kentsoeng maboteng a kahare le kantle ho fana ka sebaka se boreleli, se lekanang bakeng sa pente kapa wallpaper. HPMC e ntlafatsa thepa e 'maloa ea putty ea lebota, e thusa ho ntlafatsa ts'ebetso ea eona le litšobotsi tsa ts'ebeliso. Mona ke tse ling tsa mesebetsi ea bohlokoa eo HPMC e e bapalang ho li-putty tsa grade ea meralo:

Ho boloka metsi: HPMC e sebetsa e le moemeli oa ho boloka metsi mme e thusa ho laola boemo ba mongobo ka har'a putty nakong ea ho folisa. E thibela ho omisoa ka potlako le ho netefatsa hore metsi a lekaneng a samente, a khothalletsa phekolo e nepahetseng le nts'etsopele ea matla.

Ho sebetsa le ho ata: HPMC e ntlafatsa ts'ebetso le ho ata ha lebota la putty, ho etsa hore ho be bonolo ho kopanya, ho sebelisa le ho hasana holim'a metsi. E fana ka ho tsitsa ha tranelate le ho ntlafatsa phallo ea thepa, ho nolofatsa ts'ebetso e boreleli le ho fokotsa boiteko bo hlokahalang nakong ea troweling.

Ho khomarela: HPMC e ntlafatsa ho khomarela ha li-putty tsa lebota ho li-substrates tse fapaneng tse kang konkreite, samente kapa bokaholimo ba masonry. E matlafatsa matla a tlamahano le ho fokotsa monyetla oa delamination kapa peeling ka nako.

Khanyetso ea Crack: Ho eketsoa ha HPMC ho thusa ho ntlafatsa khanyetso ea marako a putty. E fokotsa shrinkage mme e fokotsa sebopeho sa crack ka lebaka la ho omisa kapa ho sisinyeha ha mocheso. Thepa ena e etsa hore putty e tšoarelle nako e telele 'me e thusa ho boloka sebaka se se nang moroalo.

Sag Resistance: HPMC e kenya letsoho ho hanyetsang sag ea li-putty tsa lebota ha e sebelisoa libakeng tse otlolohileng. E thusa putty ho boloka sebopeho sa eona mme e thibela deformation e feteletseng kapa ho putlama nakong ea kaho, ho netefatsa botenya ba lebota.

Nako ea ho Bula: HPMC e eketsa nako e bulehileng ea putty ea lebota, e bolelang nako eo thepa e lulang e sebelisoa ka mor'a ho kopanya. E lumella fensetere ea nako e telele ea kopo 'me e na le thuso ka ho khetheha ha u sebetsa libakeng tse kholoanyane kapa tlas'a maemo a phahameng a mocheso.

Palo e nepahetseng ea HPMC e sebelisitsoeng leboteng la putty e ipapisitse le lintlha tse joalo ka botsitso bo lakatsehang, maemo a tikoloho le sebopeho se ikhethileng sa sehlahisoa. Baetsi ba sehlopha sa meralo ea HPMC hangata ba fana ka litataiso le likhothaletso tsa ho e kenyelletsa lits'ebetsong tsa putty ea lebota. Ho khothalletsoa ho leka ho latela litaelo tsa moetsi ho fihlela ts'ebetso e lakatsehang le boleng ba lebota la putty.
