Hydroxypropyl Methylcellulose (HPMC) ndi ether yofunikira ya cellulose yokhala ndi ntchito zambiri pantchito yomanga. Ndi polima yosungunuka m'madzi yomwe imapezeka posintha mankhwala a cellulose. Ili ndi kusungunuka kwamadzi bwino, kukhuthala, kupanga mafilimu, kugwirizanitsa, kutsekemera ndi zina, choncho imagwira ntchito zosiyanasiyana pazipangizo zomangira.
1. Tondo la simenti ndi konkire
Mumatope a simenti ndi konkire, HPMC imagwiritsidwa ntchito kwambiri ngati chowonjezera, chosungira madzi komanso chomangira. Ntchito zake zazikulu ndi izi:
Kukula kwamphamvu: HPMC imatha kukulitsa kukhuthala kwa matope a simenti kapena konkire, potero kumapangitsa kuti ntchito yomanga ikhale yosavuta kufalitsa ndikugwira ntchito. Kuphatikiza apo, matope okhuthala amatha kumamatira bwino gawo lapansi ndikuchepetsa kuthekera kwa ufa ndi kugwa.
Mphamvu yosungira madzi: HPMC ili ndi mphamvu yosungira madzi, yomwe ingachepetse kutaya kwa madzi mumatope kapena konkire, kuwonjezera nthawi ya hydration reaction ya simenti, motero kumapangitsanso mphamvu yomaliza ndi kukhazikika. Izi ndizofunikira makamaka m'malo owuma kapena kutentha kwambiri, chifukwa zimatha kuteteza kusweka ndi kusakwanira kolimba komwe kumachitika chifukwa cha kuyanika simenti msanga.
Anti-sagging effect: Pomanga pamalo oyimirira, HPMC imatha kuletsa matope kapena zokutira kuti zisagwere pansi, kusunga makulidwe a yunifolomu komanso kuphimba bwino.
2. Zomata za matailosi
Mu zomatira matailosi, udindo wa HPMC ndi wovuta kwambiri. Sikuti amangowonjezera kumamatira kwa zomatira, komanso kumapangitsanso kugwira ntchito panthawi yomanga. Mwachindunji, amawonetsedwa motere:
Kuwongolera kumamatira: HPMC imathandizira kumamatira pakati pa zomatira matailosi ndi matailosi ndi magawo, kuwonetsetsa kukhazikika ndi kulimba kwa matailosi mutayala.
Kupititsa patsogolo ntchito yomanga: HPMC ikhoza kuwonjezera nthawi yotsegulira zomatira matayala, ndiko kuti, kuwonjezera nthawi yomwe malo a matailosi angasinthidwe asanayambe kuuma, zomwe ndizofunikira kwambiri kwa ogwira ntchito zomangamanga ndipo zimatha kutsimikizira kuti kuyika matayala kulondola.
Anti-slip: Kwa matailosi akulu akulu kapena pomanga pamalo oyimirira, HPMC imatha kupewa kutsetsereka kwa matailosi, potero kumapangitsa kuti zomangamanga zikhale bwino.
3. Njira yotchinjiriza kunja kwa khoma
M'makina akunja otchinjiriza khoma, HPMC imagwiranso ntchito yosungira madzi, kukhuthala ndi kulumikizana. Dongosolo lotsekereza lakunja limafuna kuti zida zomangira zikhale ndi zinthu zabwino zosungira madzi kuti zitsimikizire kuti matope omangirira sangalephereke chifukwa cha kutaya madzi ochulukirapo panthawi yomanga ndi kuchiritsa. Kuphatikizika kwa HPMC kumathandizira magwiridwe antchito, kuyanika ndi kukana kwa matope, potero kumapangitsa kuti ntchito yomanga ikhale yolimba komanso yolimba.
4. Zida zodziyimira pawokha
Pazinthu zodziyimira pawokha, HPMC imagwira ntchito yowongolera madzi ndikuwongolera kusunga madzi. Izi zimafunikira kusanjika pakumanga, koma sizingatulutse matope kapena stratification. The thickening zotsatira za HPMC akhoza kusunga chifanane cha zinthu popanda kukhudza fluidity, kuonetsetsa kuti pansi ndi lathyathyathya ndi yosalala.
5. Putty ufa
HPMC imagwiritsidwanso ntchito kwambiri mu putty powder pamakoma amkati ndi kunja kwa nyumba. Ikhoza kupititsa patsogolo mapangidwe ndi kulimba kwa ufa wa putty, kupititsa patsogolo kumamatira kwake kukhoma, ndikuwongolera nthawi yowuma komanso kukana kwa ufa wa putty. Makamaka m'madera ouma, HPMC imatha kuteteza bwino kusweka kapena kugwa chifukwa cha kutaya madzi mofulumira kwa putty powder.
6. Ntchito zina
Kuphatikiza pa ntchito zazikuluzikulu zomwe zili pamwambazi, HPMC imagwiranso ntchito m'madera ena omangamanga, monga gypsum-based products, zokutira madzi, zopangira grouting, sealants, ndi zina zotero. chowonjezera chachikulu mu zomangira.
Hydroxypropyl methylcellulose ili ndi ntchito zambiri zofunika pantchito yomanga. Imawongolera bwino ntchito yomanga ya zida zomangira popititsa patsogolo ntchito yomanga zinthu zopangidwa ndi simenti ndi gypsum, kuwonjezera nthawi yogwira ntchito, kukulitsa kulumikizana, ndikuwongolera kukana kwa ming'alu. Chifukwa chake, chiyembekezo chakugwiritsa ntchito kwa HPMC pakumanga kwamakono ndi otakata kwambiri, ndipo ndikukula kosalekeza kwaukadaulo wa zomangamanga, ntchito ya HPMC idzakhala yotchuka kwambiri.
