Ho na le lintlha tse ngata tse amang ts'ebeliso ea hydroxypropyl methylcellulose HPMC linthong tsa moaho, haholo samente e entsoeng ka gypsum, ka tsela e latelang:
1 ho boloka metsi
Hydroxypropyl methylcellulose bakeng sa kaho e thibela ho kenngoa ho feteletseng ha metsi ke substrate, 'me ha gypsum e behiloe ka ho feletseng, metsi a lokela ho bolokoa ka har'a samente ka hohle kamoo ho ka khonehang. Tšobotsi ena e bitsoa ho boloka metsi 'me e lekana ka ho toba le viscosity ea tharollo e khethehileng ea hydroxypropyl methylcellulose ka har'a stucco. Ha li-viscosity tsa tharollo li phahame, li phahamisa matla a eona a ho boloka metsi. Hang ha metsi a ntse a eketseha, matla a ho boloka metsi a tla fokotseha. Lebaka ke hobane metsi a ntseng a eketseha a hlapolla tharollo ea hydroxypropyl methylcellulose bakeng sa kaho, e leng se bakang ho fokotseha ha viscosity.
2 anti-sagging
Plaster e nang le thepa ea anti-sag e lumella ba sebelisang liphahlo hore ba sebelise lijase tse teteaneng ntle le ho sisinyeha, hape ho bolela hore samente ka boeona ha se thixotropic, e neng e ka thellela fatše nakong ea kopo.
3 Fokotsa viscosity, kaho e bonolo
Plaster ea gypsum e nang le viscosity e tlase ebile e bonolo ho e etsa e ka fumanoa ka ho kenyelletsa lihlahisoa tse fapaneng tsa moaho tsa hydroxypropyl methylcellulose. Ha u sebelisa limaraka tse tlaase tsa viscosity ea mohaho o khethehileng oa hydroxypropyl methylcellulose, tekanyo ea viscosity e fokotsehile Kaho e ba bonolo, empa matla a ho boloka metsi a tlaase-viscosity hydroxypropyl methylcellulose bakeng sa kaho e fokola, 'me chelete e eketsehileng e lokela ho eketseha.
4 Ho lumellana ha stucco
Bakeng sa palo e tsitsitseng ea seretse se omeletseng, ho na le chelete e ngata ho hlahisa molumo o phahameng oa seretse se metsi, se ka finyelloang ka ho eketsa metsi a mangata le li-bubble tsa moea. Empa palo ea lipompong tsa metsi le moea e ngata haholo
