Kuchulukitsa Kukula ndi Kukana Kusokoneza Zida za Simenti Wokhala ndi HPMC

Chiyambi
Zipangizo zochokera kumenga ndizofunika kwambiri pomanga, kupereka umphumphu wofunikira chifukwa cha nyumba, milatho, ndi zomangamanga. Komabe, zinthuzi zimakonda kusokonekera komanso kukhazikika chifukwa cha zinthu zosiyanasiyana zachilengedwe komanso zamakina. Kuphatikiza kwa zowonjezera kukhala zosakanikirana ndi njira yofufuzira bwino yophunzitsira katundu wawo. Hydroxypypyl methylcellulose (hpmc) yatuluka ngati chowonjezera chowonjezera pakusintha magwiridwe antchito a simenti.

Njira Zochitikira
HPMC ndi ethel ellulose polymer imadziwika kuti madzi ake osungidwa, akuwonjezera a Vicency, ndi katundu wopanga mafilimu. Mukawonjezeredwa ndi zida za simenti, hpmc zimakopa njira ya hydration, kapangidwe kake, ndi ma matrix ku matrix m'njira zingapo:

Kusunga kwamadzi komanso kuwongolera kwamadzi: hpmc kumathandizira kusungidwa kwamadzi mu simenti kusakaniza koyenera, komwe ndikofunikira kuti mugwiritse ntchito mankhwala osokoneza bongo. Mafuta olimbitsa thupi ndi ofunikira pakupanga calcium silmium silemium hydrate (CSS) gel, chomangira chachikulu chomwe chimapatsa mphamvu simenti. Posunga madzi, HPMC imawonetsetsa kuti hydrate ikupitilira nthawi yayitali, yomwe imatsogolera ndi microstruous microstruous microstructuctuctution.

Kusintha kwa Vission: Kuwonjezera kwa HPMC kumawonjezera mapangidwe a mmero, omwe amasintha kugwirira ntchito komanso kukhazikika kwa kusakaniza. Izi ndizopindulitsa kwambiri pakuchepetsa tsankho komanso magazi, pomwe madzi ndi tinthu tating'onoting'ono timasiyana ndi osakaniza. Kusakaniza kokhazikika kumapangitsa kugawa yunifolomu ya sitementi, kumathandizira kuti ndi zinthu zolimba komanso zosagonjetseka.

Mapangidwe a filimu ndi kusintha kapangidwe kosinthika: HPMC imapanga filimu yosinthika yosinthika mkati mwa simenti. Kanemayu amatha kupindika microcracks ndikuwonjezera mphamvu yonse. Kuphatikiza apo, hpmc imakopa kapangidwe ka pachimake pochepetsa kupatsa kwa plulation ndi kugawa kwampikisano. Kapangidwe kakang'ono ka mpiru kumachepetsa, potero amalimbikitsa kukana zinthu zachilengedwe monga zozungulira zaulere, zowukira zamankhwala, ndi mpweya.

Ubwino wa HPMC mu zinthu za simenti
Kuphatikizika kwa hpmc mu simenti zomwe zidaperekedwa ndi zopatsa zambiri zopindulitsa, makamaka kutembenukira mozungulira zolimbitsa thupi komanso kusokonekera kwachuma:

Kuchulukitsa Kuchuluka: Kutha kwa HPMC kuti musunge madzi ndi kuwongolera hydration kumathandiza mwachindunji kukhazikika kwazinthu za simenti. Kuonetsetsa kuti muli ndi matenda athunthu komanso kukhala okhwima, zida zowoneka bwino kuwonetsa kusintha kwa zinthu zosiyanasiyana monga kuwonongeka kwa sulfate, alkali-silika zochita (ASKI), ndi chloride neattage. Kukhazikika kwakukulu kumatanthauzira moyo wautali wantchito ndikuchepetsa ndalama zokonzanso.

Kuthetsa Kukana Kulimbana: Kusanja zinthu za simenti kumatha kuchitika chifukwa cha ma pulasitiki, kuyanika, zipsinjo zotentha, ndi katundu wamakina. HPMC imathandizira kuthetsa mavuto awa kudzera mu madzi ake osungira ndi mawonekedwe a filimu. Mwa kusunga chinyontho chokwanira nthawi yochiritsa, hpmc imachepetsa chiopsezo cha ming'alu yamapulasitiki. Zimakhudzanso kuchepa kwaukadaulo komanso kukulitsanso matrix duckitity kumatanthauzanso kuti zinthuzo zitha kuyamwa bwino, kuchepetsa mwayi wofatsa.

Kugwiritsa ntchito bwino ntchito komanso kugwiritsa ntchito njira zosakanizira ma viction a HPMC kumathandizira pakugwirira ntchito bwino ndikugwiritsa ntchito zida za simenti. Izi ndizofunikira kwambiri pakumanga kagulu kamene mungagwiritse ntchito ndi kuthamanga ndikofunikira. Kutha kwa HPMC popewa tsankho komanso magazi kumatsimikizira kuti kusakanikirako kumakhala kosakhazikika komanso kovomerezeka, komwe ndikofunikira kuti mukwaniritse zomaliza zapamwamba komanso kukhulupirika.

Ntchito Zothandiza
HPMC imagwiritsidwa ntchito m'malo osiyanasiyana okhudzana ndi simenti ndi ntchito, aliyense wopindula ndi zinthu zake zapadera:

Matope ndi ma pusterters: mu matope ndi mapulani opanga, hpmc imathandizira kugwirira ntchito, kutsatira, komanso kukana. Izi ndizofunikira kwambiri kuti zithetse bwino malo osalala, olimba mu mkati ndi kunja.

Zodzikongoletsera zodzipangitsa: hpmc zimayenda bwino kayendedwe kazinthu komanso kukhazikika kwa mankhwala odzipangitsa okha, kuonetsetsa yunifolomu, malo opanda phokoso. Izi ndizopindulitsa kwambiri pakugwiritsa ntchito pansi pomwe mulingo wokhazikika komanso wokhalitsa amafunikira.

Tile zomatira: hpmc imawonjezera chotsatsa ndi nthawi yotseguka ya zomata za matailosi, kupereka nthawi yogwira ntchito ndi mgwirizano wamphamvu. Izi zimabweretsa kukhazikika kwamphamvu ndikulimbana ndi zingwe zomata, zomwe zingayambitse matayala kuti asang'ambike kapena kugwa.

Kukonza: Kukonza mativa ndi zopukutira, hpmc kumathandizira kuti zinthu ziziyenda bwino ndikuchepetsa kuti kukonzanso ndikokhazikika komanso zopanda pake. Izi ndizofunikira pakubwezeretsa kukhulupirika kwa nyumba zowonongeka.

Shotcrete ndi konkire yopukutira: HPMM imathandizira coutheon ndi kutsatira shotcrete, kuchepetsa kubwezeretsanso ndikuonetsetsa kuti mulipi. Izi ndizofunikira kwambiri pakumanga ndi kubisalira pansi pomwe kulimba komanso kusokonekera.

Kuphatikizika kwa hydroxypropyl methylcellulose (hpmc) mu zinthu za simenti kumapangitsa kulimba mtima kwawo ndikulimbana. Mwa kukonza chitetezo chamadzi, kusintha mavidiyo, ndikupanga mafilimu osinthika mkati mwa simentant Matrix, HPMC imayankhula zazikulu zokhudzana ndi hydration, kapangidwe kake, komanso kugawa. Kusintha kumeneku kumabweretsa zida zomwe zimakhala zolimba, kufooka, komanso kosavuta kugwira ntchito, komwe kumamasulira kumayiko ena okhazikika komanso odalirika kwambiri. Pamene makampani omanga akupitiliza kufunafuna njira zothandizira magwiridwe antchito komanso kukhala ndi moyo wautali wa zinthu zomwe zili mmenga, hpmc imakhala yothandiza kwambiri ndi ntchito zambiri.
