Gusaba HPMC muri sima zishingiye kuri sima na plaster

1. Incamake ya HPMC
HPMC (HydroxyPropyl methylcellus, hydroxypropyl methylcellseliulose) ni uruganda rukora amazi ya polymer rwabonetse kubijyanye na selile ya selile. Ifite amazi meza yoroheje, imitungo yo gushinga filime, imitungo yo kunyeganyega, kunyeganyega, kugumana amazi n'amahekwa, kandi bikoreshwa cyane mu kubaka, kurera, ubuvuzi, ibiryo n'izindi nganda. Mu nganda zubwubatsi, cyane cyane muri plaster ishingiye kuri sima na Stucco, HPMC, nkibibazo, birashobora kunoza uburyo bwo kubaka, ibintu byumubiri no kuramba byingenzi kugirango utezimbere imiterere yibikoresho byo kubaka.

Kunoza imikorere yubwubatsi
Mugihe cyubwubatsi bwa plaster ishingiye kuri sima na Stucco, HPMC irashobora kunoza cyane amazi nigituba cyo gucika intege, bigatuma gahunda yo kubaka yoroshye kandi ikarenga. Imikorere yihariye ni:

Kwagura igihe cyo gufungura: HPMC irashobora gutinza uburyo bwa mbere bwo kwihagararaho, bityo bikongera igihe cyo gufungura ibikoresho. Ibi byemerera abakozi b'ubwubatsi gukorera igihe kirekire, cyane cyane iyo bakeka ahantu hanini, kandi bakabuza sima gucika intege vuba kandi bigira ingaruka ku ngaruka zo kubaka.
Kunoza Adhesion: plave-plaster ishingiye kuri plaster hamwe na stucco bikoreshwa muguhuza hagati yubuso butandukanye. HPMC irashobora kunoza neza ibihumyi, kugabanya ipfundo ryo gukuramo, kandi urebe neza ko adhesion ihamye ya plaster cyangwa stucco.

Gutezimbere
Muri sima ishingiye ku matongo n'icya, uruhare rugumana amazi ya HPMC ni ngombwa cyane. Amazi muri sima atandukana vuba, cyane cyane mubushyuhe bwinshi kandi nibidukikije byumye, bishobora kuganisha byoroshye kuri sima ituzuye, bityo bikagira ingaruka ku mbaraga zituzuye, bityo bigira ingaruka ku mbaraga n'imbaraga za plaster cyangwa minisiteri. Mugutezimbere ibikoresho byamazi, HPMC irashobora gutinda ku gipimo cy'amazi n'amazi ya sima, bityo rero byongera imbaraga za plaster ya sima cyangwa imigenzo ya minisiteri no kureba neza.

Ongera urwanire
Kuva sima ishingiye kuri place na Stucco itanga imihangayiko yimbere mugihe cyimbere mugihe cyimbere, bakunze gucamo, cyane cyane mubidukikije bifite ubushyuhe bunini. HPMC irashobora kugabanya neza ibibaho byumye mugutezimbere imiterere no kugumana amazi yo gucika intege. Byongeye kandi, amahano ya HPMC itezimbere imbaraga zihuza urwego rwa plaster hamwe nurwego ruse, bigabanya imiterere yo guhagarara nimbaraga zo hanze, kandi biteza imbere ihohoterwa rya plaster.

Kunoza uburyo
HPMC ikoreshwa nkuwijimye muri plams zishingiye kuri sima na plaster, zishobora kunoza imitungo yuburyo bwo gutandukana. Irashobora gutuma ibitonyanga bifite amazi meza kandi byagaragaye neza, wirinde ibibazo byubwubatsi bikabije cyangwa binini cyane. Kurugero, HPMC irashobora kunoza ihagarikwa ryibitonyanga, kugirango ibice byiza muri sima bisuzugurwe, birinda gutura, kwirinda gutura, no kumenya neza no kumenya neza no kubaka ibintu bimwe.

Gukaraba
HPMC irashobora guteza imbere amazi-yoza plaster-plaster ishingiye kuri sima hamwe na stucco no kugabanya isuri yisuri hejuru yubuso bwubuso bwubuso. Niba sima yubuso bwubutaka bufite kurwanya amazi bihagije, bizagira ingaruka kumuvuduko n'imbaraga zikomeye. HPMC irashobora kongera amazi ya sima ya sima hamwe n'ibitotsi kugira ngo birinde isuri ikabije no kwishuka hanze, bityo bitera ubuziraherezo.

3. Dosage n'ibyifuzo byo gusaba HPMC
Igipimo cya HPMC mubisanzwe biterwa nubwoko bwa sima ishingiye cyangwa stucco nibisabwa. Muri rusange, ingano ya HPMC yongeyeho ni 0.1% -0.5% ya sima, ariko amafaranga yihariye agomba guhindurwa ukurikije ibintu nyirizina.

Imiterere yo kubika: HPMC ifite urwego runaka rwa hygroscopicity kandi rugomba kubikwa mubidukikije byumye kugirango wirinde kwinjiza ahantu heza biganisha ku kugabanuka mubikorwa byacyo.
Ubufatanye nizindi nguzanyo: Iyo ikoreshwa muburyo bwo kongeramo, ni ngombwa kwemeza ko HPMC ihuza izindi mbomvugo kugirango irinde kuba ireba imikorere rusange.

4. Ibyiza nibibazo bya HPMC

Ibyiza:
Kurinda ibidukikije: Nkibikoresho bya polymer karemano, HPMC ifite amasoko arambye yibikoresho fatizo kandi afite umutwaro muto kubidukikije.
Gutezimbere imikorere yubwubatsi: HPMC irashobora kunoza imikorere yubwubatsi ya plaster ishingiye kuri sima na Stucco, bigatuma inzira yo kubaka byoroshye kandi byihuse.
Kurambagiza kuramba: byongera imbaraga z'amazi, byo kurwanya amazi no gukaraba amazi ku mato ya sima na plaster, kugirango ubashe ubuzima bwa serivisi.

Ikibazo:
Ikibazo cyibiciro: Igiciro cya HPMC ni hejuru cyane, cyane cyane iyo gikoreshwa kurwego runini, gishobora kongera ibiciro rusange byibikoresho.
