Ihame ryakazi rya HydroxyPropyl Methylcellse muri minisiteri

HydroxyPropyl Methylcellse (HPMC)Ese amazi yafashwe n'amazi akoreshwa cyane mu nganda z'ubwubatsi, cyane cyane muri minisiteri ishingiye kuri sima, imppesi ishingiye ku basimba. Nkuko minisiteri yongeyeho, HPMC irashobora kunoza imikorere yubwubatsi, kunoza ibikorwa, kubyutsa, kugumana amazi no guhanagura minisiteri, bityo bikabangamira imiterere rusange ya minisiteri.

1. Imiterere y'ibanze ya HPMC

HPMC yabonetse cyane cyane guhinduranya kwangirika kwa selile, kandi ifite amazi meza, kubyimba, gushiraho film, amavuta no gutuza. Imitungo yayo ikomeye ikubiyemo:

Amazi yoroheje: Irashobora gushonga mumazi akonje cyangwa ashyushye kugirango akore igisubizo gisobanutse cyangwa gisobanutse neza.
Ingaruka nziza: Irashobora kongera imbaraga zikomeye igisubizo kandi ikagaragaza ingaruka nziza zijimye mugihe gito.
Ifungwa ry'amazi: HPMC irashobora gukurura amazi no kubyimba, no kugira uruhare mu kugumana amazi muri minisiteri kugira ngo amazi atabuze vuba.
Imiterere yuburyo: Ifite thixotropy nziza, ifasha kunoza imikorere yubwubatsi ya minisiteri.

2. Uruhare nyamukuru rwa HPMC muri minisiteri

Uruhare rwa HPMC muri minisiteri rugaragara cyane muri ibi bikurikira:

2.1 Gutezimbere kugumana amazi

Mugihe cyubwubatsi bwa sima burere, niba amazi ahita yihuta cyangwa yakiriwe neza na shingiro, bizaganisha kuri sima idahagije ya swaction reaction kandi igira ingaruka ku iterambere. HPMC forms a uniform mesh structure in the mortar through its hydrophilicity and water absorption and expansion ability, locks in moisture, reduces water loss, thereby extending the open time of the mortar and improving construction adaptability.

2.2 ingaruka mbi, kunoza imikorere ya minisiteri

HPMC ifite ingaruka nziza, ishobora kongera virusi ya minisiteri, ituma umuryango ugira phostity mwiza, kandi wirinde kuri minisitiri neza, kandi wirinde kuri minisiteri yo kubyutsa, gutandukanya amaraso no kuva amaraso. Muri icyo gihe, kubyimba kwinshi birashobora kunoza iyubakwa rya minisiteri, byoroshye gusaba no ku rwego mugihe cyubwubatsi, no guteza imbere imikorere yubwubatsi.

2.3 Kuzamura amarira no kunoza amazina ya minisiteri

Mubikorwa nka tile abiziritse, Major Bortar na Plaque Mresir, imbaraga zo guhunika kwa minisiteri ni ngombwa. HPMC ikora firime imwe ya polymer hagati yibanze no gupakira binyuze mubikorwa bigize film, bitezimbere imbaraga zo guhunika kwa minisiteri kubamburwa, bityo bigabanya ibyago byo gucika intege no kugwa.

2.4 Kunoza imikorere yubwubatsi no kugabanya Sag

Kubijyanye no kubaka hejuru yubuso (nka plastan sposter cyangwa tile ibwubatsi), minisiteri ikunda gusebanya cyangwa kunyerera kubera uburemere bwacyo. HPMC yongerera imihangayiko na anti-sag ya minisiteri, kugirango minisiteri ishobora kubahiriza hejuru yifatizo mugihe cyubwubatsi buhagaritse, bityo biteza imbere umutekano wubwubatsi.

2.5 Gutezimbere Kurwanya no Gutezimbere Kuramba

Mortar ikunze gucika kubera kugabanuka mugihe cyibikorwa bikomeye, bigira ingaruka kumishinga. HPMC irashobora guhindura imihangayiko yimbere ya minisiteri kandi igabanye igipimo cya gari. Muri icyo gihe, mugutezimbere guhinduka kwa minisiteri, bigira ibishishwa byiza munsi yubushyuhe cyangwa guhangayika hanze, bityo bitera kuramba.

2.6 bigira ingaruka ku igenamigambi rya minisiteri

HPMC igira ingaruka mugihe cya minisiteri ihindura umuvuduko wa sima hydtion reaction. Umubare ukwiye wa HPMC irashobora kwagura igihe cyubwubatsi bwa minisiteri kandi ikareba igihe cyo guhinduka mugihe cyubwubatsi, ariko ikoreshwa cyane irashobora kwagura igihe cyo gushiraho kandi igira ingaruka kumasaha yagenwe kandi bikagira ingaruka kumushinga, bityo dosage igomba kugenzurwa neza.

3. Ingaruka za Dosage ya HPMC kumafaranga ya minisiteri

Igipimo cya HPMC muri minisiteri muri rusange ari hasi, mubisanzwe hagati ya 0.1% na 0.5%. Umuyoboro wihariye uterwa nubwoko bwa minisiteri no kubaka:

Dosage yo hasi (≤0.1%): Irashobora guteza imbere ihohoterwa ryamazi no kuzamura imikorere ya minisiteri, ariko ingaruka mbi zirakomeye.

Igipimo giciriritse (0.1% ~ 0.3%

Umuyoboro mwinshi (≥0.3%): Bizagenda byiyongera cyane kuri minisiteri, ariko birashobora kugira ingaruka kumasura, kwagura igihe cyo gushinga, kandi ntikibishobora kubaka.

Nkikibazo gikomeye kuri minisiteri,HpmcDufite uruhare runini mugutezimbere kugumana amazi, kunoza imikorere yubwubatsi, kuzamura ubushishozi no kurwanya. Kwiyongera ku gaciro HPMC irashobora kunoza cyane imikorere rusange ya minisiteri no kuzamura ireme ryumushinga. Muri icyo gihe, dosage igomba kugenzurwa kugirango irinde ingaruka mbi mugihe cyo gushyiraho igihe n'amakuba yubwubatsi. Mugihe kizaza, hamwe no guteza imbere inganda zubwubatsi, ibyifuzo bya HPMC mubikoresho bishya byo kubaka icyatsi bizaba bigutse.
