Zotsatira za hydroxypropyl methylcelulose pa nyonga ya konkriti

Hydroxypylmmyl (HPMC) ndi yogwiritsidwa ntchito chogwiritsidwa ntchito chofananira ndi wothandizika madzi, amagwiritsidwa ntchito konkriti. Itha kukhudzanso mphamvu ya konkriti posintha miyambo yake, malo osasunga madzi ndikukhazikitsa nthawi.

Sinthani mphamvu yolimba
Kafukufuku wasonyeza kuti ma cellulose akusintha ma viscositotious osiyanasiyana adzakulitsa mphamvu yovuta kwambiri ya konkriti pamlingo wotsika. Kutsitsa mafalo, kusintha kwakukulu. Kuchuluka kwa etherse koyenera kumatha kukonza bwino ntchito ya konkriti ndikuwonjezera mphamvu yovuta.

Sinthani kugwirira ntchito komanso kusungidwa kwamadzi kwa konkriti
Hydroxypypyl methylcellulose imatha kusintha kwambiri kugwiritsidwa ntchito komanso kusungidwa kwamadzi kwa konkriti, pothandiza pothandiza kuwonjezera mapangidwe ndi mphamvu ya konkriti. Mwachitsanzo, zomwe zili hydroxpyl methylcellulose ndi 0.04%, konkritiyo ili ndi ntchito yabwino kwambiri, zomwe zili mu mpweya ndi 2.6%, ndi mphamvu zopondera zidafika pamwamba.

Zimakhudzanso madzi ndi kufulumira kwa konkriti
Mlingo wa hydroxypropyll methylcellulose imakhudzanso kwambiri chifukwa cha konkriti. Kuchuluka kwa hydroxypypyl methylcellulose (mwachitsanzo, mlingo womwe uli mkati mwa 0,04% mpaka 0.08%) amatha kukonza kugwiritsidwa ntchito kwa konkriti (pafupifupi 0,08) kungapangitse kukula kwa konkriti kumachepera. , zomwe zingakhudze mphamvu ya konkriti.

Kubwezera
Hydroxypropyl a Methylcellulose ali ndi mphamvu yobwereza, yomwe imatha kupereka nthawi yokhazikika, kulola konkriti kukhala ndi nthawi yotakataka panthawi yomanga, ndikuthandiza konkriti.

Mphamvu ya hydroxypropyl methylcellulosilose pa mphamvu ya konkriti imachitika. Kuchuluka kwa hydroxypropyll methyllulose kungakulitse mphamvu yovuta yolimbana ndi konkriti, kusintha kwake kugwirira ntchito ndi kusungidwa kwamadzi, potero kuthandiza kukonza ma concrete. Komabe, kuphatikiza zochuluka kumatha kuwononga madzi ndi kukulira konkriti komwe kungasokoneze mphamvu ya konkriti. Chifukwa chake, mukamagwiritsa ntchito hydroxypropyl methylcellulose, ndikofunikira kusankha mtundu woyenera malinga ndi momwe zinthu zilili.
