Hydroxypropyl methylcellulose (HPMC) ni polymer ikora cyane ikoreshwa cyane mubikorwa bitandukanye harimo nubwubatsi. Muri porogaramu ya gypsumu, HPMC ikora nk'inyongera yingirakamaro hamwe ninyungu zinyuranye zifasha kuzamura imikorere rusange hamwe nubwiza bwimikorere ya gypsumu.
Intangiriro kuri hydroxypropyl methylcellulose:
Hydroxypropyl methylcellulose ni polymer ya kimwe cya kabiri ikomoka kuri selile, polymer karemano iboneka mu bimera. HPMC ikomatanyirizwa hamwe no kuvura selile hamwe na okiside ya propylene na methyl chloride, bikavamo ibice bifite imitungo yiyongereye ugereranije na selile y'ababyeyi. Urwego rwo gusimbuza (DS) rwamatsinda ya hydroxypropyl hamwe na mikorobe ya mikorobe kumugongo wa selile igena imiterere yihariye ya HPMC.
Ibiranga HPMC:
Kubika amazi:
HPMC ifite uburyo bwiza bwo kubika amazi kandi irashobora gukora firime yoroheje hejuru ya gypsumu kugirango igabanye amazi. Ibi nibyingenzi kugirango ugere kumiterere myiza yo gukira no kwirinda gukama hakiri kare stucco.
Kunoza imashini:
Kwiyongera kwa HPMC byongera imikorere ya plaster, byoroshye kuvanga, gushira no gukwirakwiza. Kunoza kunoza bifasha gutanga neza no gukwirakwiza ahantu hatandukanye.
Kugenzura igihe cyagenwe:
HPMC yemerera kugenzura igihe cyo gushiraho plaster. Muguhindura ibirimo HPMC, abayikora barashobora kudoda ibihe kugirango bahuze ibisabwa byumushinga, bakemeza neza kandi birangire.
Ongera amasaha yo gufungura:
Gufungura igihe nigihe plaster ikomeza gukora mbere yuko ishiraho. HPMC yongereye amasaha yo gufungura kugirango itange abanyabukorikori n'abakozi igihe cyoroheje cyo gusaba no kurangiza imirimo.
Kongera imbaraga:
Imiterere ya firime ya HPMC ifasha kunoza umubano hagati ya plaster na substrate. Ibi nibyingenzi byingenzi kugirango hamenyekane kuramba no kuramba hejuru yububiko.
Kurwanya ibice:
HPMC ifasha kugabanya amahirwe yo gucika muri plaster mukongera imbaraga zayo nimbaraga. Ibi nibyingenzi kugirango ubungabunge uburinganire bwimiterere yubuso bwigihe kirekire.
Kunoza imvugo:
Rheologiya bivuga imyitwarire no guhindura ibintu. HPMC irashobora guhindura imiterere ya rheologiya ya gypsumu, ikayiha guhuza kwifuzwa kugirango byoroshye gukoreshwa no kuringaniza.
Ikoreshwa rya HPMC muri gypsumu:
Gypsumu:
Muri gypsumu, HPMC ikoreshwa mugutezimbere amazi, gukora no gufatira hamwe. Ifasha kandi kugenzura igihe cyo gushiraho no kunoza imikorere rusange ya gypsumu ishingiye kuri stucco.
Amashanyarazi ashingiye kuri sima:
HPMC ikoreshwa cyane muri plaque ishingiye kuri sima aho ari inyongera yingenzi kugirango igere kuri rheologiya isabwa, igihe cyo gufungura no gufatira hamwe. Kugenzura ibihe byagenwe bifite akamaro kanini kubikorwa binini byubaka.
Lime paste:
Amashanyarazi ya lime yunguka hiyongereyeho HPMC kugirango yongere amazi kandi akore. Guhuza polymer nibikoresho bishingiye ku ndimu bituma ihitamo neza umurage no gusana.
Sisitemu yo hanze no kurangiza sisitemu (EIFS):
HPMC nigice cyingenzi muri porogaramu za EIFS, zifasha kunoza imiterere, guhinduka no guhangana. Ibikoresho byayo bigumana amazi bifite agaciro cyane muri sisitemu yo hanze ya stucco.
mu gusoza:
Hydroxypropyl methylcellulose ninyongera nziza muburyo bwa gypsumu bitewe nintererano zinyuranye mugutunga amazi, gukora, gushiraho igihe, kugumya no kurwanya. Haba ikoreshwa muri plaster, sima, lime cyangwa sisitemu yo kubika urukuta rwo hanze, HPMC igira uruhare runini mugutezimbere imikorere rusange nubwiza bwa plasta. Mugihe ibikorwa byubwubatsi bikomeje kugenda byiyongera, HPMC ihindagurika kandi yizewe byatumye iba igice cyingenzi mubikorwa bya plaster bigezweho, bituma kuramba no gutsinda mubikorwa bitandukanye byubwubatsi.
