Tšebeliso ea hydroxypropyl methylcellulose ka seretseng

1. Ho boloka metsi

Hydroxypropyl methylcellulose bakeng sa kaho e thibela mongobo ho kena leboteng.Metsi a lekaneng a lula seretseng, e le hore samente e be le nako e teletsana ea ho nosetsa.Ho bolokoa ha metsi ho lekana le viscosity ea tharollo ea cellulose ether seretseng.Ha viscosity e phahame, ho boloka metsi ho molemo.Hang ha limolek'hule tsa metsi li eketseha, ho boloka metsi ho fokotseha.Hobane bakeng sa tekanyo e ts'oanang ea tharollo ea hydroxypropyl methylcellulose ea kaho, ho eketseha ha metsi ho bolela ho fokotseha ha viscosity.Ntlafatso ea ho boloka metsi e tla lebisa ho atolosoeng ha nako ea pheko ea seretse se ntseng se hahuoa.

2. Ntlafatsa mokhoa oa ho aha

Ts'ebeliso ea hydroxypropyl methylcellulose HPMC e ka ntlafatsa kaho ea seretse, ea etsa hore sehlahisoa sa seretse se be le ts'ebetso e ntle ea ho jala, ho fokotsa ho khomarela lisebelisoa, ho nolofatsa kaho, le ho fokotsa ho ikitlaetsa ha basebetsi.

3. Li-bubble content

Li-bubble tse phahameng tsa moea li etsa hore ho be le chai e ntle ea seretse le ho sebetsa hantle, ho fokotsa sebopeho sa crack.E boetse e theola boleng ba matla, e bakang ketsahalo ea "liquefaction".Li-bubble tsa moea hangata li ipapisitse le nako ea ho sisinyeha.Lihlahisoa li sebelisoa haholo ho ntlafatsa ts'ebetso ea lisebelisoa tsa mohaho oa hydraulic, tse kang samente le gypsum.Litšeng tse entsoeng ka samente, e ntlafatsa ho boloka metsi, e eketsa khalemelo le linako tse bulehileng, 'me e fokotsa ho fokotseha.

4. Anti-sagging

Seretse se setle se hananang le sag se bolela hore ha se sebelisoa ka mekhahlelo e teteaneng ha ho na kotsi ea ho theoha kapa ho theoha.Sag resistance e ka ntlafala ka hydroxypropyl methylcellulose e khethehileng.Haholo-holo hydroxypropyl methylcellulose e sa tsoa etsoa bakeng sa kaho e ka fana ka thepa e ntle ea anti-sagging ea seretse.

5. Bokhoni ba ho koloba

Lihlahisoa tse loketseng tsa cellulose ether li ka ntlafatsa viscosity ea seretse ha li ntse li etsa bonnete ba hore mosebetsi oa holim'a metsi le ho khomarela metsi a seretse, e leng se etsang hore seretse se be le ts'ebetso e ntlafetseng ea ho kolobisa substrate, esita le haeba e sebelisoa ho EPS kapa XPS, joalo-joalo Ho tla ba teng ha ho na ketsahalo e kobehileng le e sa kolobiseng sebakeng se khethehileng sa motheo.
