HPMC (Hydroxypropyl Methylcellulose) ndi zinthu za polima zomwe zimagwiritsidwa ntchito kwambiri pomanga ndipo zimakhala ndi thupi komanso mankhwala apadera. HPMC nthawi zambiri amagwiritsidwa ntchito ngati chowonjezera pamakampani omanga kuti apititse patsogolo zida zomangira, makamaka mumatope, ufa wa putty, zokutira ndi zinthu za simenti.
1. Kugwiritsa ntchito mumatope
M'matope omanga, HPMC imagwiritsidwa ntchito kwambiri kupititsa patsogolo ntchito yomanga. Kusungirako madzi ake, kukhuthala komanso anti-sag katundu kumapangitsa HPMC kukhala ndi gawo lofunikira mumatope osakaniza okonzeka, zomatira matailosi a ceramic, matope amiyala ndi minda ina.
Kusungirako madzi: HPMC imatha kupititsa patsogolo mphamvu yosungira madzi mumatope ndikuletsa madzi kuti asasunthike mwachangu, potero kuwonetsetsa kuti simenti imayenda bwino komanso kulimbitsa mphamvu zomangira komanso kukana kwamatope. Izi ndizofunikira makamaka m'malo otentha kwambiri kuti zisawonongeke komanso kutaya mphamvu chifukwa cha kuyanika kwamatope kwambiri.
Kukhuthala: HPMC imatha kusintha mawonekedwe amadzimadzi komanso kukhuthala kwamatope, kupangitsa kuti matope azikhala osalala mukamagwiritsa ntchito komanso kukhala kosavuta kupanga. Panthawi imodzimodziyo, imathanso kupititsa patsogolo kunyowa ndi kumamatira kwa matope kuzinthu zoyambira, kuonetsetsa kuti matope akhoza kumangirizidwa mwamphamvu pakhoma kapena zipangizo zina zapansi.
Anti-sag: HPMC imatha kuletsa matope kuti asagwere kapena kugwa pomanga pamalo oyimirira, makamaka popanga zigawo zokhuthala. Kusintha kwake kwa viscosity kumapangitsa kuti matope azikhala bwino pakumanga kwa facade komanso kuti asagwe.
2. Ntchito mu zomatira matailosi ceramic
Pakati pa zomatira matailosi a ceramic, HPMC imagwiritsidwa ntchito makamaka kupititsa patsogolo magwiridwe antchito komanso magwiridwe antchito a matailosi a ceramic. M'mamangidwe amakono, matailosi a ceramic amagwiritsidwa ntchito kwambiri kukongoletsa khoma ndi pansi, kotero kuti zomatira ndizofunika kwambiri.
Kupititsa patsogolo mphamvu yomangirira: HPMC imawonetsetsa kuti simenti ikhale yokwanira kwambiri posunga madzi ndi kukhuthala kwake, motero kumapangitsanso kulimbikitsana pakati pa zomatira ndi matailosi a ceramic ndi gawo lapansi. Izi sizimangowonjezera moyo wautumiki wa matailosi, komanso zimawalepheretsa kugwa chifukwa chosakwanira kumamatira.
Maola owonjezera otsegulira: Panthawi yoyika matayala a ceramic, ogwira ntchito yomanga nthawi zambiri amafunikira nthawi yokwanira kuti asinthe momwe matayala a ceramic alili. Kuphatikiza kwa HPMC kumatha kuwonjezera nthawi yotsegulira zomatira, kupatsa ogwira ntchito yomanga nthawi yochulukirapo kuti agwire ntchito ndikusintha, potero kupititsa patsogolo ntchito yomanga.
Pewani kutsetsereka: Mukayika matailosi a ceramic pankhokwe, HPMC imatha kuletsa matailosi a ceramic kuti asasunthike ndikukhalabe okhazikika pomanga. Izi sizimangochepetsa zovuta zomanga, komanso zimakulitsa luso la zomangamanga.
3. Ntchito mu putty ufa
Ntchito ya HPMC mu putty powder ndiyofunikanso kwambiri, makamaka pakuwongolera magwiridwe antchito, kusunga madzi komanso kukana kwa putty.
Kupititsa patsogolo ntchito: Kuwonjezera HPMC ku ufa wa putty kungapangitse kugwiritsa ntchito putty kukhala kosavuta komanso kupewa zokopa, kuuma ndi zochitika zina panthawi yomanga. Pa nthawi yomweyo, fluidity ndi ductility wa putty angathenso bwino, kupanga kumanga mosavuta.
Kusungidwa kwa madzi owonjezereka: Ntchito yosungiramo madzi ya HPMC ikhoza kuonetsetsa kuti putty imakhala ndi madzi okwanira pakhoma, kupeŵa ming'alu kapena kuchotsa ufa chifukwa cha kutaya madzi mofulumira. Makamaka m'malo owuma kapena otentha kwambiri, HPMC imatha kuchedwetsa kutuluka kwamadzi, kuwonetsetsa kuti putty imalumikizana bwino ndi gawo lapansi.
Limbikitsani kukana kwa ming'alu: Panthawi yowumitsa, putty ikhoza kusweka chifukwa cha kutayika kwa madzi osagwirizana. HPMC, kupyolera mu mphamvu yake yosungiramo madzi yunifolomu, imalola kuti putty iume mofanana, motero kuchepetsa kwambiri chiopsezo chosweka.
4. Kugwiritsa ntchito zokutira
HPMC imathandizanso kukhuthala, kusunga madzi komanso kukhazikika mu zokutira zokhala ndi madzi.
Kukulitsa mphamvu: Mu zokutira, HPMC imagwiritsidwa ntchito makamaka kusinthira kukhuthala kwa zokutira, kupangitsa kuti zokutira zizikhala zofananira panthawi yotsuka kapena kupopera mbewu mankhwalawa, ndipo imakhala yabwino komanso yogwira ntchito. Panthawi imodzimodziyo, imatha kuteteza utoto kuti usagwedezeke ndikuwonetsetsa kuti penti ikugwira ntchito.
Kusungirako madzi: HPMC imatha kuletsa zokutira kuti zisatuluke mwachangu panthawi yomanga, zomwe zimakhudza kapangidwe kake. Makamaka m'madera omwe ali ndi kutentha kwambiri kapena mpweya wabwino, kusungirako madzi kwa HPMC kumatha kusintha kwambiri mapangidwe a ❖ kuyanika.
Kukhazikika kwamphamvu: HPMC imathanso kupititsa patsogolo kukhazikika kwa zokutira, kuletsa delamination ndi mvula ya zokutira pakusungidwa kwa nthawi yayitali, ndikusunga zokutira kuti zikhale zofanana komanso zokhazikika.
5. Kugwiritsa ntchito zinthu za simenti
HPMC imagwiritsidwanso ntchito kwambiri popanga simenti yopangidwa ndi precast ndi zida zodziyimira pawokha. Itha kusintha kukana kwa ming'alu, mphamvu yopondereza komanso kusalala kwa zinthu za simenti.
Kupititsa patsogolo kukana kwa ming'alu: Mphamvu yosungiramo madzi ya HPMC imawonetsetsa kuti simenti sidzaphwanyika chifukwa cha kutuluka kwamadzi mwachangu panthawi yowumitsa, potero kumapangitsa kuti chinthucho chikhale cholimba komanso cholimba.
Sinthani mawonekedwe a pamwamba: HPMC imapangitsa kuti zinthu za simenti zikhale zosalala komanso zosalala, zimachepetsa kutulutsa thovu komanso ming'alu yapamtunda, ndikuwongolera mawonekedwe azinthu zomalizidwa.
Limbikitsani ntchito yomanga: Pazida zodziyimira pawokha, kukhuthala kwa HPMC kumatha kupangitsa kuti zinthu zisamayende bwino, kupangitsa kuti zomangamanga zapansi zikhale zofananira komanso zosalala, komanso kupewa kukhazikika komanso kusweka.
6. Ntchito zina
Kuphatikiza pa ntchito zazikuluzikulu zomwe zili pamwambapa, HPMC imagwiranso ntchito yofunikira pakuletsa madzi, zida zotchinjiriza, ma caulking agents ndi magawo ena. Pakati pa zipangizo zopanda madzi, kusungirako madzi ndi kukhuthala kungathe kupititsa patsogolo ntchito yomanga ndi kuteteza madzi azinthu; pakati pa zinthu zotchinjiriza matenthedwe, HPMC imathandizira kulimbitsa mphamvu zomangira komanso kukhazikika kwazinthuzo.
Kugwiritsa ntchito kwakukulu kwa HPMC pantchito yomanga ndi chifukwa champhamvu zake zakuthupi ndi zamankhwala. Monga chowonjezera chofunikira chomanga, HPMC sichingangowonjezera kusungika kwa madzi, kukhuthala ndi kukana kwa zinthu, komanso kupititsa patsogolo ntchito yomanga komanso mtundu wazinthu zomalizidwa. Pakumanga kwamakono, kaya ndi matope, zomatira matailosi, ufa wa putty, zokutira ndi zinthu za simenti, HPMC imagwira ntchito yosasinthika, kulimbikitsa kupita patsogolo kwaukadaulo wazomangamanga ndikuwongolera bwino ntchito yomanga.
