Kodi Zowonjezera 5 Zofunikira pa Mchere ndi Ziti? Buku Lophunzitsira Lonse

Chiyambi

Kapangidwe kamakono kasintha kwambiri kuposa zosakaniza zachikhalidwe za mchenga ndi simenti. Makina a matope osakaniza ndi ouma a masiku ano ndi opangidwa mwaluso kwambiri kuti akwaniritse zofunikira zogwirira ntchito monga mphamvu yolimba, kukana ming'alu, kugwira ntchito mosavuta, kusunga madzi, kulimba, komanso kukana chilengedwe.

Kuti zinthu izi zitheke, zowonjezera mankhwala zimakhala ndi gawo lofunika kwambiri. Ngakhale zimagwiritsidwa ntchito pang'ono, zowonjezerazo zimatsimikiza momwe makina a matope amagwirira ntchito kuposa china chilichonse kupatula simenti.

Nkhaniyi ikufotokoza zazowonjezera zisanu zofunika kwambiri pa matope, ntchito zawo, njira zawo, ndi chifukwa chake ndizofunikira kwambiri pa zomangamanga zamakono.

1. Cellulose Ether (HPMC / MHEC / HEC)

Ma cellulose ethers ndiye maziko a ukadaulo wamakono wa matope. Mitundu yomwe imagwiritsidwa ntchito kwambiri ndi iyi:

Ntchito Zazikulu

Kusunga Madzi

Ma cellulose ether amaletsa kutaya madzi mwachangu ku zinthu zofewa, zomwe zimapangitsa kuti simenti iume bwino.

Kukonza Kugwira Ntchito

Zimathandiza kuti zisamafalikire, zisamafalikire, komanso kuti zisamagwire bwino ntchito.

Kutsegulira Nthawi Yowonjezera

Zimachedwetsa kuumitsa pamwamba, zomwe zimapangitsa kuti kuyika kukhale kosavuta.

Kupambana kwa Kusakhazikika

Zimawonjezera kukhuthala ndipo zimaletsa kutsetsereka pamalo oyima.

Chifukwa Chake Ndi Chofunika Kwambiri

Popanda ether ya cellulose:

  • Mtondo umataya madzi mwachangu kwambiri
  • Kusagwirizana bwino kumachitika
  • Kusweka kwa ming'alu kumawonjezeka

Cellulose ether imaonedwa kuti ndichowonjezera chofunikira kwambiri mu makina osakaniza ndi matope ouma.

2. Ufa wa Polima Wotha Kumwazikanso (RDP)

Ufa wa polima wosungunukansondi chowonjezera chosinthidwa ndi polima chomwe chimapangitsa kusinthasintha ndi kumamatira.

Mitundu yodziwika bwino ndi iyi:

  • VAE (Vinyl Acetate Ethylene)
  • Ma copolymer a acrylic
  • Ma polima a Styrene-acrylic

Ntchito Zazikulu

Kukulitsa Kumatira

RDP imapanga filimu yosinthasintha ya polima yomwe imalimbitsa mgwirizano pakati pa matope ndi substrate.

Kukonza Kusinthasintha

Amachepetsa kusweka kwa zinthu zopangidwa ndi simenti.

Kukana kwa Ming'alu

Zimathandiza kuchepetsa kupsinjika komwe kumachitika chifukwa cha kusintha kwa kutentha ndi kayendedwe ka kapangidwe kake.

Kukana Madzi

Zimachepetsa kulowerera kwa madzi ndipo zimathandizira kulimba.

Chifukwa Chake Ndi Chofunika Kwambiri

RDP imasintha makina olimba a simenti kukhalamatope osinthasintha, ogwira ntchito bwino kwambiriyoyenera kugwiritsa ntchito masiku ano monga:

  • Zomatira za matailosi
  • Machitidwe a EIFS
  • Konzani ma mortar

3. Superplasticizers (PCE - Polycarboxylate Ether)

Ma Superplasticizer ndi zinthu zochepetsera madzi zomwe zimagwiritsidwa ntchito kwambiri m'makina amakono a simenti.

Ntchito Zazikulu

Kuchepetsa Madzi

Amachepetsa kufunikira kwa madzi pamene akusungabe kugwira ntchito bwino.

Kupititsa patsogolo Mphamvu

Kuchepa kwa madzi kumabweretsa mphamvu yowonjezereka yopondereza.

Kupititsa patsogolo Kuyenda kwa Madzi

Zimathandiza kuti zinthu zodzipangira zokha komanso ma grout zisamayende bwino.

Chifukwa Chake Ndi Chofunika Kwambiri

Ma Superplasticizers amathandiza:

  • Sitima yamphamvu kwambiri
  • Machitidwe odziyimira pawokha
  • Kugwiritsa ntchito konkriti yopopera

Ndi ofunikira kwambirimakina a simenti ogwira ntchito bwino komanso opanda madzi ambiri.

4. Othandizira Kuphunzitsa Mlengalenga

Zinthu zolowetsa mpweya zimalowetsa thovu la mpweya wocheperako mu matope.

Ntchito Zazikulu

Kukana Kuzizira–Kusungunuka

Mpweya wopanda kanthu umayamwa mphamvu yotambasuka kuchokera ku madzi ozizira.

Kugwira Ntchito Bwino

Amapangitsa kuti matope azigwiritsidwa ntchito mosavuta komanso kufalikira mosavuta.

Kuchuluka Kochepa

Kuchuluka kochepa kumathandizira kutenthetsa kutentha.

Chifukwa Chake Ndi Chofunika Kwambiri

Mu nyengo yozizira, zinthu zopumira mpweya ndizofunikira pa:

  • Pulasitiki yakunja
  • Ma mortar okonza misewu
  • Kapangidwe ka nyengo yozizira

Amakula bwino kwambirikulimba pansi pa nyengo zovuta.

5. Oletsa ndi Okhazikitsa Olamulira

Othandizira kuchepetsa madzi m'nthaka amayang'anira kuchuluka kwa madzi m'simenti.

Mitundu yodziwika bwino ndi iyi:

  • Asidi wa citric
  • Asidi ya Tartaric
  • Mankhwala okhala ndi phosphate

Ntchito Zazikulu

Kukhazikitsa Nthawi Yolamulira

Amachedwetsa nthawi yoyambira ndi yomaliza yokhazikitsa.

Kuwonjezera Kugwira Ntchito

Amalola nthawi yayitali yogwirira ntchito m'malo akuluakulu omanga.

Pewani Kuuma Pasadakhale

Chofunika kwambiri pa ntchito za nyengo yotentha.

Chifukwa Chake Ndi Chofunika Kwambiri

Popanda kukhazikitsa ulamuliro:

  • Mtondo ungaume mofulumira kwambiri
  • Ubwino wa pulogalamu umachepa
  • Kuchuluka kwa zinyalala

Osauka ndi ofunikira kwambirikuwongolera kutentha ndi kusinthasintha kwa zomangamanga.

Zotsatira Zogwirizana za Zowonjezera

Mu makina amakono a matope, zowonjezera sizigwira ntchito paokha.

M'malo mwake, zimagwirizana:

  • Cellulose ether → kusunga madzi + kugwira ntchito bwino
  • RDP → kusinthasintha + kumamatira
  • PCE → kuyenda + mphamvu
  • Zopumira mpweya → kulimba
  • Obwezera → Kulamulira nthawi

Pamodzi amapangadongosolo la matope loyenera bwino kwambiri.

Madera Ogwiritsira Ntchito Mtondo Wosinthidwa

Ma mortars amakono okhala ndi zowonjezera amagwiritsidwa ntchito mu:

  • Zomatira za matailosi (machitidwe a C1, C2)
  • Putty wall ndi skim coats
  • Mafakitale odziyimira okha
  • Makina oteteza kutentha a EIFS
  • Konzani ma mortar
  • Ma plaster okhala ndi gypsum

Kugwiritsa ntchito kulikonse kumafuna kuchuluka kosiyana kwa zowonjezera.

Kufunika Kwachuma

Ngakhale kuti zowonjezera zimakhala zochepa poyerekeza ndi mtengo wonse wa zopangira, zimapereka:

  • Kuchepa kwa zolephera zomanga
  • Ndalama zochepa zosamalira
  • Mwachangu kwambiri pakupanga
  • Moyo wabwino wa nyumba

Iwo ndi amodzi mwazigawo zapamwamba kwambiri za ROI mu chemistry yomanga.

Zochitika Zachilengedwe

Zowonjezera zamakono zikuchulukirachulukira:

  • Zochokera ku bio (zochokera ku cellulose)
  • VOC Yotsika
  • Kugwiritsa ntchito mphamvu moyenera popanga

Kukhazikika kwa zinthu kukukhala chinthu chofunikira kwambiri pakupanga zinthu zatsopano.

Kugwira ntchito kwa matope amakono kumadalira kwambiri zowonjezera za mankhwala. Zowonjezera zisanu zofunika kwambiri—ma ether a cellulose,RDP, ma superplasticizer, othandizira mpweya, ndi owongolera kukhazikitsa—amagwirira ntchito limodzi kuti asinthe zosakaniza zoyambira za simenti kukhala zipangizo zomangira zogwira ntchito bwino.

Kumvetsetsa zowonjezera izi kumathandiza opanga ndi makontrakitala kupanga ma mortar omwe amakwaniritsa zofunikira za zomangamanga zamakono: olimba, osinthasintha, olimba, komanso ogwira ntchito bwino.

Pamene miyezo yomanga ikupitirira kusinthika, ukadaulo wowonjezera udzakhalabe pakati pa luso lamakono mu makina a matope.
