Hydroxypropyl methylcellulose bakeng sa ho fafatsa leboteng!

Hydroxypropyl methylcellulose bakeng sa ho fafatsa leboteng!

Lihlahisoa tsa Hydroxypropyl methylcellulose bakeng sa kaho li sebelisoa haholo ho ntlafatsa ts'ebetso ea thepa ea kaho ea hydraulic, joalo ka samente le gypsum. Litšeng tse entsoeng ka samente, e ntlafatsa ho boloka metsi, e lelefatsa khalemelo le linako tse bulehileng, 'me e fokotsa ho fokotseha.

a. 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 lekanang ea tharollo ea hydroxypropyl methylcellulose e lekanang le 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.

b. Ntlafatsa kaho

Tšebeliso ea hydroxypropyl methylcellulose HPMC e ka ntlafatsa kaho ea seretse.

c. Bokgoni ba ho tlotsa

Lisebelisoa tsohle tse kenyang moea li sebetsa e le lisebelisoa tsa ho kolobisa ka ho fokotsa tsitsipano ea holim'a metsi le ho thusa likotlo tsa seretse ho hasana ha li kopane le metsi.

d. 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. Hydroxypropyl methylcellulose e khethehileng ea kaho e hlahisoang ke Khampani ea Shandong Chuangyao e ka fana ka thepa e ntle ea ho thibela ho sisinyeha ha seretse.

e. Likahare tsa Bubble

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 "liquefaction" ketsahalo. Li-bubble tsa moea hangata li ipapisitse le nako ea ho sisinyeha.

Melemo ea hydroxypropyl methylcellulose kahong ea thepa ea moaho:

Hydroxypropyl methylcellulose e na le thepa ea eona e ikhethang ts'ebelisong ea thepa ea moaho, ho tloha ho tsoakaneng ho ea ho phatlalla ho ea kahong, ka tsela e latelang:

Motsoako le tlhophiso:

1. Ho bonolo ho kopanya le phofo e omeletseng ea phofo.

2. E na le litšobotsi tsa ho hasana ha metsi a batang.

3. Emisa likaroloana tse tiileng ka katleho, ho etsa hore motsoako o be bonolo le o ts'oanang.

Phatlalatso le ho kopanya:

1. Mokhoa o omileng oa motsoako o nang le hydroxypropyl methylcellulose o ka kopanngoa habonolo le metsi.

2. Fumana ka potlako ho lumellana ho lakatsehang.

3. Ho qhibiliha ha cellulose ether ho potlakile ebile ha ho na maqhubu.

Kaho ea Marang-rang:

1. Ntlafatsa lubricity le polasetiki ho ntlafatsa machinability le ho etsa hore kaho ea sehlahisoa e be bonolo le ho potlaka.

2. Ntlafatsa litšobotsi tsa ho boloka metsi le ho lelefatsa nako ea ho sebetsa.

3. E thusa ho thibela phallo e otlolohileng ea seretse, seretse le lithaele. Eketsa nako ea ho pholisa le ho ntlafatsa katleho ea mosebetsi.

Qetello ea ts'ebetso le ponahalo:

1. Ntlafatsa matla a maqhama a li-adhesive tsa lithaele.

2. Ntlafatsa shrinkage ea anti-crack le matla a anti-cracking a seretse le boto ea motsoako oa motsoako.

3. Ntlafatsa boemo ba moea ka har'a seretse 'me u fokotse haholo monyetla oa ho phatloha.

4. Ntlafatsa ponahalo ea lihlahisoa tse felileng.

5. E ka ntlafatsa ho hanyetsa phallo e otlolohileng ea li-adhesive tsa lithaele.

Hydroxypropyl methylcellulose (HPMC) ke ether e seng ionic cellulose e entsoeng ka k'hothone e hloekileng ka letoto la mekhoa ea lik'hemik'hale. Hydroxypropylmethylcellulose (HPMC) ke phofo e tšoeu e se nang monko, e sa latsoeheng, e se nang chefo e ka qhibilihang ka metsing a batang ho etsa tharollo e hlakileng ea viscous. E na le thepa ea ho tiisa, ho tlama, ho qhalakanya, emulsifying, filimi-forming, suspending, adsorbing, gelling, surface active, ho boloka mongobo le ho sireletsa colloid.
