1) Khetho ea lihlahisoa tsa cellulose ether. Ha re bua ka kakaretso, ho na le viscosity e kholo ea cellulose ether, ho ntlafatsa phello ea eona ea ho boloka metsi, empa ho phahama ha viscosity, ho fokotsa ho qhibiliha ha eona, e leng kotsi ho matla le ts'ebetso ea kaho ea seretse; botle ba cellulose ether bo batla bo le tlase seretseng se omileng se tsoakiloeng. Ho boleloa hore ha e le hantle, ho ba bonolo ho qhibiliha. Tlas'a tekanyo e ts'oanang, ha botle bo ntlafala, ho na le phello e ntle ea ho boloka metsi.
2) Khetho ea tekanyo ea cellulose ether. Ho latela liphetho tsa tlhahlobo le tlhahlobo ea phello ea litaba tsa cellulose ether mabapi le ts'ebetso ea seretse se omeletseng se kopantsoeng, ho ka bonoa hore ha litaba tsa cellulose ether li phahame, ho molemo ho feta ho nahanoa ka litšenyehelo tsa tlhahiso, boleng ba sehlahisoa, ts'ebetso ea kaho le likarolo tse 'ne tsa tikoloho ea kaho ho khetha litekanyetso tse nepahetseng. Tekanyo ea hydroxypropyl methyl cellulose ether ka seretse se tloaelehileng sa motsoako o omileng ka ho khetheha ke 0.1 kg / t-0.3 kg / t, 'me phello ea ho boloka metsi e ke ke ea finyella litlhoko tse tloaelehileng haeba palo ea hydroxypropyl methyl cellulose ether e eketsoa ka chelete e nyenyane.

3) Ho sebelisoa ha cellulose ether ka seretse se tloaelehileng se omeletseng se omileng. Ha ho ntse ho etsoa seretse se tloaelehileng se omeletseng, ho ka eketsoa palo e loketseng ea motsoako, ka ho khetheha ka ho boloka metsi le phello e teteaneng, e le hore e ka theha phello ea composite superposition le cellulose ether, ho fokotsa litšenyehelo tsa tlhahiso le ho boloka mehloli; haeba e sebelisoa e le mong Bakeng sa cellulose ether, matla a ho kopanya a ke ke a finyella litlhoko, 'me palo e loketseng ea phofo ea latex e ka kenyelletsoang hape e ka eketsoa; ka lebaka la palo e tlase ea motsoako oa seretse, phoso ea tekanyo e kholo ha e sebelisoa e le mong. Boleng ba lihlahisoa tsa seretse se omileng se omileng.
5. Liqeto le litlhahiso
1) Ka seretse se tloaelehileng sa plastering se omeletseng, ka keketseho ea litaba tsa hydroxypropyl methylcellulose ether, tekanyo ea ho boloka metsi e ka fihla ho 96.3%, ho tsitsisa le ho teteka ho fokotsehile, 'me nako ea ho beha e lelefalitsoe. Matla a hatellang a 28d a fokotsehile, empa ts'ebetso ea kakaretso ea seretse se omeletseng se ile sa ntlafatsoa ha litaba tsa hydroxypropyl methyl cellulose ether li ne li leka-lekane.
2) Nakong ea ho lokisa seretse se tloaelehileng se omeletseng, selulose ether e nang le viscosity e loketseng le fineness e lokela ho khethoa, 'me tekanyo ea eona e lokela ho khethoa ka tieo ka liteko. Ka lebaka la palo e tlase ea motsoako oa seretse, phoso ea tekanyo e kholo ha e sebelisoa e le mong. Ho kgothaletswa ho e kopanya le mojari pele, ebe o eketsa palo ea ho eketsa ho netefatsa boleng ba lihlahisoa tsa seretse se omeletseng.
3) Seretse se omileng se kopantsoeng ke indasteri e hlahang Chaena. Ts'ebetsong ea ho sebelisa li-admixtures tsa seretse, ha rea lokela ho phehella bongata ka bofofu, empa re ele hloko haholoanyane boleng le ho fokotsa litšenyehelo tsa tlhahiso, ho khothaletsa tšebeliso ea masala a litšila tsa indasteri, 'me kannete re fihlelle ho boloka matla le ho fokotsa tšebeliso.
