Uruhare rwa HydroxyPropyl Methylcellse (HPMC) muri Gypsum plasters

Intangiriro:

Gypsim plaster, ibikoresho byakoreshejwe mu bwubatsi buzwi cyane kubinyuranya nuburyo bworoshye, byabonye iterambere rikomeye mumyaka yashize hamwe ninjizwa ryinyongera nka hydroxypropyl methylcellse (HPMC). HPMC, selile ya ether ikomoka, itanga imitungo yifuzwa yongerera imikorere kandi ikorana na gypsum plaster. Iyi ngingo isize uruhare runini rwa HPMC muri Gypsum Plaster Urukurikirane rwa Gypsum, eluctating ibiranga imiti, ibiranga imikorere, nibisobanuro bifatika.

Ibigize imiti n'imiterere ya HPMC:

HydroxyPropyl Methylcellse ikoresheje imiti ihindura imiti, bikavamo polymer-gukosora amazi hamwe nibintu bitandukanye. Imiterere yayo ya chimique igizwe n'iminyururu ya selile hamwe na methyl na hydroxyleropyl abasimbuye. Urwego rwo gusimbuza (DS) rwa methyl na hydroxyProppoxy rugira ingaruka ku buryo bugaragara imiterere ya HPMC, harimo viscosiya, ibibazo byonyine, hamwe nubushobozi bwamazi. HPMC yerekana ibintu byiza byo kugumana amazi, bikora ibisubizo bya colloidal bihamye bigira uruhare mu kunonosorwa ibikorwa no kugaza muri Gypsim Porogaramu.

Imikorere ya HPMC muri Gypsum plaster:

Kugumana amazi: HPMC ikora nka hydrophilic polymer, ikora firime yo kurinda hafi ya Gypsum, bityo irinde gutakaza amazi byihuse mugihe cyo gushiraho. Ibi byongerera ibikorwa bya plaster, kwemerera ibihe byambere byambere byo gusaba no kugabanya ibyago byo gucana cyangwa kugabanuka.

Imyitozo ya Rheology: Kwiyongera kwa HPMC bigira ingaruka kumyitwarire yuburyo bwa gypsum plaster, gutanga ibitekerezo bya pseudoplastique cyangwa imiterere yinyanja. Ibi bivamo gukwirakwira neza, kugabanya kugabanuka, no kuzamura umutungo wa thixotropic, yorohereza uburyo bworoshye bwo gusaba no kugera kumyambarire iragaruka.

Kwiyongera: HPMC yongera amarozi ya Gypsum Plaster kubantu batandukanye, barimo Masonry, beto, kandi yumye. Imiterere yimikorere ihamye hagati ya plaster na substrate iteza imbere imbaraga zububiko kandi igabanya ubujura cyangwa kugabanuka, kwemeza kuramba igihe kirekire hamwe nubunyangamugayo bwibanze.

Gushiraho igihe: Mu rwego rwo kugenzura hydration kinetike ya gypsum, HPMC ituma igenzura neza mugihe cya plaque. Ibi bituma imyirondoro yo kwipimisha ikunganijwe nibisabwa byihariye bisabwa, uhereye kumiterere yihuse kugirango hashyizweho igihe kinini kugirango habeho igihe kirekire kubikorwa bifatika cyangwa bishushanya.

Inyungu za HPMC muri Gypsum Plaster Urukurikirane:

Isome rya HPMC ritanga ibyiza byinshi kuri gypsum plaster itunganijwe:

Igikorwa cyanonosowe: Gukangurwa no kugumana amazi hamwe nuburyo bwo kugumana n'amarangamutima bivamo byoroshye, byangiza ibintu byoroshye, byorohereza korohereza no kugabanya imyanda yibintu.

Yongerewe Kuramba: Gutezimbere gusumba no gutondekanya igihe cyo kongera imbaraga, byagabanijwe kunyeganyega, no kunoza kurwanya ibintu bishingiye ku bidukikije nk'ihindagurika n'ubushyuhe.

Porogaramu zitandukanye: Abanyapopsi yahinduwe na HPMC - Pypsum Gypsum ishakisha ibyifuzo mumishinga itandukanye yo kubaka, harimo no kubumba gushimisha, gusana, gusana no kugarura, no kugarura, no kugarura.

Ibitekerezo bifatika hamwe namabwiriza yo gusaba:

Mugihe winjije HPMC muri Gypsum plaster itunganijwe, ibintu byinshi bigomba gufatwa nkamagana imikorere no kumenya neza:

Guhitamo icyiciro cya HPMC: Guhitamo icyiciro cya HPMC bigomba gushingira kubisabwa byihariye bisabwe, kwitondera ibintu nka viscosiya, kubamo amazi, no gutegeka igihe.

Kwipimisha guhuza: Kwipimisha guhuza hagati ya HPMC nibindi bikubiye cyangwa ibipimo ni ngombwa kugirango usuzume imikoranire ishobora no kwemeza imikorere yifuzwa ya plaster.

Uburyo bwo kuvanga: Uburyo bukwiye bwo kuvanga, harimo urukurikirane rwo kongeramo ibikoresho nigihe cyo kuvanga, hagomba gupima imitungo ya Plaster, hagomba gupima imitungo ya Plaster, igenamigambi, ni ngombwa kugirango ukurikirane ibipimo ngenderwaho no kubahiriza ibipimo ngenderwaho.

HydroxyPropyl MethylcellllAlose (HPMC) igira uruhare runini mu kuzamura imikorere, ibikorwa, ndetse n'imbaro ya gypsum plaque. Binyuze mu guhuza burundu amazi, uburyo bwo kwiyongera, kuzamura igihe, no gutondekanya igihe, HPMC igira uruhare mu guhuza no kwizerwa kwa Gypsum plaster ahantu hatandukanye. Mugusobanukirwa imikorere ninyungu za HPMC, abakora imyitozo barashobora kunoza plaster kugirango bahuze ibyifuzo bifatika byimishinga yo kubaka igezweho mugihe ugera ku mishinga myiza kandi igerwaho.
