Zida za Exterior Insulation and Finishing Systems (EIFS) zimagwira ntchito yofunika kwambiri popereka zotsekemera, zoteteza nyengo ndi kukongola kwa nyumba.Hydroxypropyl methylcellulose (HPMC) ndi chowonjezera chomwe chimagwiritsidwa ntchito kwambiri mu matope a EIFS chifukwa cha kusinthasintha kwake, kusunga madzi komanso kutha kuwongolera magwiridwe antchito.
1. Chiyambi cha matope a EIFS:
Mtondo wa EIFS ndi chinthu chophatikizika chomwe chimagwiritsidwa ntchito potsekereza ndikumaliza makhoma akunja.
Nthawi zambiri amakhala ndi simenti binder, aggregates, ulusi, zowonjezera ndi madzi.
Mtondo wa EIFS ukhoza kugwiritsidwa ntchito ngati choyambira cholumikizira mapanelo otsekereza komanso ngati chovala chapamwamba chothandizira kukongola komanso kuteteza nyengo.
2.Hydroxypropylmethylcellulose (HPMC):
HPMC ndi etha ya cellulose yochokera ku cellulose yachilengedwe ya polima.
Amagwiritsidwa ntchito kwambiri muzomangamanga chifukwa cha kusunga madzi, kukhuthala komanso kupititsa patsogolo ntchito.
Mu matope a EIFS, HPMC imagwira ntchito ngati rheology modifier, kupititsa patsogolo kumamatira, kugwirizanitsa ndi kukana kwa sag.
3. Zosakaniza za formula:
a.Zomangira simenti:
Portland Cement: Amapereka mphamvu ndi kumamatira.
Simenti yosakanikirana (monga simenti ya miyala ya laimu ya Portland): Imawonjezera kukhazikika komanso imachepetsa kuchuluka kwa mpweya.
b.Kuphatikiza:
Mchenga: Kuchuluka kwake komanso mawonekedwe ake ophatikizika bwino.
Zophatikizika zopepuka (monga zowonjezera perlite): Sinthani mphamvu zotchinjiriza kutentha.
C. CHIKWANGWANI:
Magalasi a fiberglass osagwira alkali: Imakulitsa mphamvu zolimba komanso kukana ming'alu.
d.Zowonjezera:
HPMC: kusunga madzi, kugwira ntchito, ndi kukana kwamadzi.
Wothandizira mpweya: Kupititsa patsogolo kukana kuzizira.
Retarder: Imawongolera kuyika nthawi m'malo otentha.
Zosintha za Polima: Sinthani kusinthasintha komanso kulimba.
e.Madzi: Ofunikira pa hydration ndi magwiridwe antchito.
4. Makhalidwe a HPMC mumatope a EIFS:
a.Kusungirako Madzi: HPMC imayamwa ndikusunga madzi, kuonetsetsa kuti madzi azikhala nthawi yayitali ndikuwongolera magwiridwe antchito.
b.Kugwira ntchito: HPMC imapatsa matope kusalala komanso kusasinthika, kupangitsa kuti ikhale yosavuta kupanga.
C. Anti-sag: HPMC imathandiza kupewa matope kuti asagwere kapena kugwa pa malo ofukula, kuonetsetsa makulidwe ofanana.
d.Kumamatira: HPMC imawonjezera kumamatira pakati pa matope ndi gawo lapansi, kumalimbikitsa kumamatira kwanthawi yayitali komanso kukhazikika.
e.Kukaniza kwa mng'alu: HPMC imathandizira kusinthasintha komanso kugwirizanitsa mphamvu zamatope ndikuchepetsa chiopsezo chosweka.
5. Njira yosakaniza:
a.Njira yonyowa kale:
Nyowetsanitu HPMC mu chidebe choyera ndi pafupifupi 70-80% ya madzi onse osakanikirana.
Sakanizani bwino zouma zouma (simenti, zophatikizika, ulusi) mu chosakanizira.
Pang'onopang'ono onjezani yankho la premoistened HPMC pamene mukuyambitsa mpaka kugwirizana komwe mukufuna.
Sinthani kuchuluka kwa madzi ngati pakufunika kuti mukwaniritse ntchito yomwe mukufuna.
b.Dry mixing njira:
Dry mix HPMC ndi zosakaniza youma (simenti, aggregates, ulusi) mu chosakanizira.
Pang'onopang'ono yonjezerani madzi ndikuyambitsa mpaka kugwirizana komwe mukufuna.
Sakanizani bwino kuti muwonetsetse kugawa kwa HPMC ndi zosakaniza zina.
Kuyesa Kugwirizana kwa C.: Kuyesa kogwirizana ndi HPMC ndi zina zowonjezera kuti zitsimikizire kuyanjana koyenera ndi ntchito.
6. Tekinoloje yogwiritsira ntchito:
a.Kukonzekera kwa gawo lapansi: Onetsetsani kuti gawo lapansi ndi loyera, louma komanso lopanda zowononga.
b.Ntchito Yoyambira:
Ikani EIFS Mortar Primer ku gawo lapansi pogwiritsa ntchito trowel kapena zida zopopera.
Onetsetsani kuti makulidwe ake ndi ofanana ndi kuphimba bwino, makamaka kuzungulira m'mphepete ndi m'makona.
Ikani bolodi losungunula mumtondo wonyowa ndikulola nthawi yokwanira kuti achire.
C. Topcoat Kugwiritsa Ntchito:
Ikani topcoat ya EIFS pamwamba pa chochiritsira chochiritsidwa pogwiritsa ntchito trowel kapena zida zopopera.
Maonekedwe kapena mawonekedwe omaliza momwe amafunira, kusamala kuti akwaniritse zofanana ndi zokongola.
Chiritsani topcoat molingana ndi malingaliro a wopanga kuti muteteze ku nyengo yovuta.
7. Kuwongolera ndi kuyesa kwabwino:
a.Kusasinthasintha: Yang'anirani kusasinthasintha kwa matope panthawi yonse yosakaniza ndikugwiritsa ntchito kuti muwonetsetse kuti mofanana.
b.Adhesion: Kuyesa kumamatira kumachitika kuti awone mphamvu ya mgwirizano pakati pa matope ndi gawo lapansi.
C. Kugwira ntchito: Unikani momwe mungagwirire ntchito pogwiritsa ntchito kuyezetsa kugwa ndi kuwunika pakumanga.
d.Kukhalitsa: Yezetsani kulimba, kuphatikiza kuzungulira kwa kuzizira ndi kutsekereza madzi, kuti muwunikire ntchito yayitali.
Kugwiritsa ntchito HPMC kupanga matope a EIFS kumapereka maubwino ambiri pogwira ntchito, kumamatira, kukana kwa sag komanso kulimba.Pomvetsetsa momwe HPMC imagwirira ntchito komanso kutsatira njira zoyenera zosakanikirana ndi kugwiritsa ntchito, makontrakitala amatha kukwaniritsa kukhazikitsa kwapamwamba kwa EIFS komwe kumakwaniritsa magwiridwe antchito ndikuwonjezera kukongola kwanyumba ndi moyo wautali.
