HPMC, yomwe imadziwikanso kuti hydroxypropyl methylcellulose, ndiyowonjezera yomwe imagwiritsidwa ntchito m'mafakitale osiyanasiyana.M'makampani omanga, HPMC imagwiritsidwa ntchito kwambiri pazinthu zopangira simenti monga putty powder, gypsum, ndi matope a simenti.HPMC imakhala ndi gawo lofunikira pakuwongolera magwiridwe antchito a ufa wa putty popereka magwiridwe antchito abwino, mphamvu zolumikizana komanso kusunga madzi.Komabe, pamene HPMC imagwiritsidwa ntchito pa putty powder, chodabwitsa chotchedwa "foaming" chimachitika.M'nkhaniyi, tikufufuza zomwe zimayambitsa matuza ndikukambirana njira zopewera.
Kodi matuza ndi chiyani ndipo chifukwa chiyani zimachitika?
Matuza ndi chodabwitsa cha mpweya thovu kapena matuza pamwamba pa putty ufa pambuyo kumanga.Izi zikhoza kuchitika mwamsanga mutagwiritsa ntchito kapena pakapita nthawi, malingana ndi chifukwa chake.Matuza amatha chifukwa cha zinthu zingapo kuphatikiza kusakonzekera bwino kwa gawo lapansi, kugwiritsa ntchito pansi pazovuta zachilengedwe kapena kugwiritsa ntchito zinthu zosagwirizana.Zifukwa zopangira thovu la HPMC ndi putty powder ndi izi:
1. Kusagwirizana pakati pa HPMC ndi zina zowonjezera: HPMC imagwiritsidwa ntchito nthawi zambiri pamodzi ndi zowonjezera zina monga superplasticizers, retarders, ndi air-entraining agents.Komabe, ngati zowonjezerazi sizigwirizana, zimatha kuchita thovu.Izi zimachitika chifukwa zowonjezera zimasokoneza wina ndi mnzake kuti agwire ntchito yomwe akufuna, zomwe zimapangitsa kusakanizika kosakhazikika komanso kusamata bwino kwa gawo lapansi.
2. Kusakaniza kosakwanira: Pamene HPMC ikusakanikirana ndi putty powder, kusakaniza koyenera ndikofunikira kwambiri.Kusakanikirana kosakwanira kungayambitse HPMC kusonkhana pamodzi ndikupanga zilumba mu kusakaniza.Zilumbazi zimapanga mawanga ofooka pamwamba pa ufa wa putty, womwe ungayambitse matuza.
3. Kusungirako madzi: HPMC ndi yotchuka chifukwa cha kusungirako madzi, omwe ndi abwino kwa putty powder.Koma ngati ufa wa putty ukhala ndi chinyezi chambiri, umayambitsa matuza.Izi nthawi zambiri zimachitika pamene putty powder amagwiritsidwa ntchito pa chinyezi chambiri kapena pamalo omwe sanachiritsidwe bwino.
4. Njira yosagwiritsa ntchito bwino: Kusagwiritsa ntchito bwino kungayambitsenso matuza.Mwachitsanzo, ngati putty itayikidwa mokhuthala kwambiri, imatha kutsekereza matumba a mpweya pansi.Ma thovu amlengalengawa amatha kukulirakulira ndikupangitsa thovu.Momwemonso, ngati putty ikagwiritsidwa ntchito mwachangu kapena mwamphamvu kwambiri, ipanga mgwirizano wofooka ndi gawo lapansi, zomwe zingayambitsenso matuza.
Mmene Mungapewere Kutuluka matuza
Kupewa kuchita thovu mukamagwiritsa ntchito HPMC ndi ufa wa putty kumafuna kusamala kwambiri ndi zida, njira komanso momwe chilengedwe chimakhudzira.Nawa maupangiri opewera matuza:
1. Sankhani zowonjezera zowonjezera: Mukamagwiritsa ntchito HPMC, ndikofunikira kusankha zowonjezera zomwe zimagwirizana.Izi zimathandiza kuti chisakanizocho chikhale chokhazikika komanso kuti chowonjezera chilichonse chimagwira ntchito yake popanda kusokoneza ena.
2. Sakanizani mofanana: HPMC iyenera kusakanizidwa mokwanira ndi putty powder kuti iwonetsetse kugawa.Izi zimathandiza kupewa zotupa ndi zofooka mawanga pamwamba pa putty ufa.
3. Kuwongolera chinyezi: Kuwongolera chinyezi ndikofunikira mukamagwiritsa ntchito HPMC ndi putty powder.Onetsetsani kuti ufa wa putty sukumana ndi chinyezi chambiri pakumanga, ndipo pewani kumanga pansi pa chinyezi chambiri kapena kunyowa.Ngati ndi kotheka, gwiritsani ntchito dehumidifier kuti muchepetse chinyezi chomwe chili mumlengalenga.
4. Gwiritsani Ntchito Njira Yoyenera Yogwiritsira Ntchito: Njira yoyenera yogwiritsira ntchito idzathandizanso kupewa matuza.Ikani ufa wa putty mu woonda, wosanjikiza ndikuupaka pansi ndi trowel kapena chida china choyenera.Pewani kugwiritsa ntchito putty ufa wokhuthala kwambiri, mwachangu kapena mwamphamvu kwambiri.
5. Ganizirani za gawo lapansi: Gawo laling'ono lomwe ufa wa putty umakhudzanso kuopsa kwa matuza.Onetsetsani kuti gawo lapansi lachiritsidwa bwino, kutsukidwa ndikukonzedwa musanagwiritse ntchito ufa wa putty.Ngati ndi kotheka, choyambira chingagwiritsidwe ntchito kukonza mgwirizano pakati pa gawo lapansi ndi ufa wa putty.
Pomaliza, matuza amatha kukhala vuto lokhumudwitsa komanso losawoneka bwino mukamagwira ntchito ndi HPMC ndi putty powder.Komabe, izi zitha kupewedwa ndi chidwi ndi zida, njira komanso momwe chilengedwe chimakhalira.Posankha zowonjezera zomwe zimagwirizana, kusakaniza bwino, kulamulira chinyezi, kugwiritsa ntchito njira zoyenera zogwiritsira ntchito, ndikuganizira gawo lapansi, mukhoza kuonetsetsa kuti nthawi zonse zimakhala zosalala, zopanda thovu.Monga otsogola opanga HPMC, tadzipereka kupereka zinthu zapamwamba kwambiri zomwe zimakwaniritsa zosowa za makasitomala athu.Tikukhulupirira kuti nkhaniyi yakhala yothandiza kumvetsetsa chifukwa chake HPMC ndi putty powder thovu komanso momwe angapewere.
