Hydroxypropyl methylcellulose (hpmc)ndi malo wamba osungunuka osungunuka omwe amagwiritsidwa ntchito kwambiri pantchito yomanga. Kugwiritsa ntchito konkriti kumatha kukonza kwambiri zinthu za konkriti ndipo zimathandizanso kuti zikhale zabwino.
1. Kukonzanso ma conrostrate ma conrostructuctuctuctuctunce yolemba hpmc
HPMC imatha kukonza bwino microstraction konkriti kudzera mu kusungidwa ndi madzi. Panthawi youmitsa konkriti, kusinthana ndi kuchepa kwa madzi ndikomwe kumayambitsa zofooka zamkati monga ma pores ndi ming'alu ya micro. HPMC imatha kupanga filimu yopumira yopumira madzi kuti muchepetse kuchepa kwamadzi, potero kuchepetsa nkhawa komanso kuchuluka kwa ming'alu mkati mwa konkriti ndikusintha ma conving. Microstructustectution iyi imathandiza mwachindunji ndi kuvunda kwa konkriti.
2. Sinthani kukana kukana
Mapulogalamu apulasikisi apulasitiki ndi mvula yamasauti ku konkriti panthawi yolimba ndi nkhani zofunika kwambiri zomwe zikukhudza kulimba. Mankhwala osungidwa a madzi a HPMC amachepetsa kununkhira kwa konkriti ndipo amachepetsa kupezeka kwa ming'alu yoyambirira yapulasitiki. Kuphatikiza apo, mankhwala ake amagwira pa simenti pa simenti amatha kuchepetsa kupsinjika kwamkati ndikuchepetsa mapangidwe a ming'alu yowuma. Izi zimapangitsa konkriti pang'ono kuti zisawonongeke zachilengedwe pakugwiritsa ntchito nthawi yayitali.
3. Kulimbana kopitilira muyeso kwa mankhwala
Konkriti nthawi zambiri imawonetsedwa ndi zowononga monga ma asidi, alkali kapena mchere, ndi kuwukira kwa mankhwala kumathandizira kuwonongeka kwake. HPMC imatha kuchepetsa kwambiri kulowa kwa media yakumanja popititsa patsogolo kuphatikiza konkriti ndi konkriti. Kuphatikiza apo, kapangidwe ka HPMC kuli ndi kuchepa kwa mankhwala ena, komwe kungalepheretse mankhwala pakati pa zowononga ndi konkriti.
4. Kusintha magwiridwe antchito ozungulira
M'magawo ozizira, ma free-thaw ndi amodzi mwazomwe zimayambitsa kuwonongeka kwa ma contictete. Kuchulukitsa kwaulere kwa chinyezi mkati mwa simenti kumatha kuyambitsa ming'alu, potero kuchepetsa mphamvu. Pofuna kukonza magwiridwe antchito osasunga madzi komanso kugawa kolumikizana, hpmc amapanga chinyezipo ndi matembenuzidwe ophatikizidwa kwambiri ndikuchepetsa mathithi aulere, potengera kuwonongeka kwaulere.
5. Konzani zomangamanga ndikusinthasintha
HPMC imagwiranso ntchito bwino komanso younikirana yothira zinthu zosakanikirana, zomwe zimatha kusintha. Kuchita bwino kumapangitsa kuti zikhale zosavuta kukwaniritsa kachulukidwe kakang'ono kwambiri pambuyo pakuthira konkriti ndikuchepetsa kupezeka kwa zilema ngati masitepe ndi tsankho. Izi zopanda pake zimathandizanso kukonza nthawi yayitali ya konkriti.
Mosamala pakugwiritsa ntchito
Ngakhale HPMC ili ndi zotsatira zabwino zambiri pa kukhazikika kwa konkriti, Mlingo wake umayenera kulamulidwa mwadongosolo. HPMC imatha kuwononga mphamvu yoyambirira ya konkriti kapena pulasitiki yambiri. Pogwiritsa ntchito njira, mlingo ndi kusakaniza radio ya HPMC iyenera kuthandizidwa kudzera poyesa malinga ndi zosowa zapadera. Kuphatikiza apo, magwiridwe antchito a HPMC adzakhudzidwanso ndi kutentha kwa chilengedwe, chinyezi komanso zinthu zina, kotero kusintha koyenera kumafunikira kupangidwa mosiyanasiyana.
Monga kosakaniza konkriti yothandiza,Hpmcamatenga gawo lalikulu pakusintha konkriti. Imawonetsa zoteteza m'malo osiyanasiyana m'malo osiyanasiyana posintha ma conrostructuctuctuctucence ya konkriti, kukhazikika kukana, kukonzanso vuto la mankhwala kukana ndi kuphwanya-Thaw. Komabe, mu ukadaulo weniweni, umafunikira kugwiritsidwa ntchito molingana ndi zochitika zina ndipo akufunika kusewera nawo mokwanira kumayendedwe ake. Ndi chitukuko chinanso cha ukadaulo, chiyembekezo cha kugwiritsa ntchito kwa HPMC mu konkriti chidzakhala chowonjezera.
