Hydroxypylropyl (HPMC) ndi polymer yosiyanasiyana yomwe nthawi zambiri imagwiritsidwa ntchito m'mafakitale osiyanasiyana, kuphatikiza kumanga, mankhwala, chakudya, ndi zodzola. Pomanga, HPMC imachita mbali yofunika kwambiri monga zowonjezera za simenti, makamaka popititsa patsogolo ntchito yolimba.
1.Introduction to HPMC:
HPMC ndi polymer yopanda madzi yosungunuka, yosungunuka yamadzi yochokera ku cellulose. Nthawi zambiri imagwiritsidwa ntchito ngati thiccener, Bander, kanema wakale, ndi madzi osungitsa madzi. M'mapulogalamu omanga, HPMC imagwiritsidwa ntchito kusinthira katundu wa simenti. Zosinthazi zimaphatikizapo kukulitsa mphamvu, kusungidwa kwamadzi, kotsatira, komanso kugwira ntchito.
Zilinso zolimbikitsa kulimba mphamvu:
Musanakambirane momwe hpmc imathandizira kugwirizanitsa Mphamvu, ndikofunikira kumvetsetsa zinthu zomwe zimapangitsa kuti zikhale zolumikizana muzinthu:
Kukonzekera kwapadziko: mkhalidwe wa gawo lapansi umakhudza kwambiri mphamvu. Pamalo oyera, owuma amapereka zotsatsa bwino poyerekeza ndi mawonekedwe osalala kapena odetsedwa.
Zomatira Zomadabwitsa: Zomatira zogwiritsidwa ntchito komanso kuyerekezera kwake ndi zinthu za gawo lapansi zomwe zimathandizanso kuti mudziwe kulimba mtima.
Makina ogwiritsira ntchito makina: Zosagwirizana ndi microscopic pamtunda zimapangitsa kugwirizanitsa makina ndi zomatira, kukulitsa mphamvu.
Kuyanjana kwa Mafuta: Kuyanjana pakati pa zomatira ndi gawo lapansi, monga hydration zimachitika muzinthu za mmenga, zimathandizira kuti mukhale ndi mphamvu.
3.Mechanisms ya HPMC pakuwongolera mphamvu yolumikizira:
HPMC imathandizira kulimbitsa mphamvu kudzera pamachitidwe angapo, kuphatikiza:
Kusunga kwamadzi: HPMC ili ndi madzi osungidwa ambiri, omwe amalepheretsa kuyanika kwa zomatira ndi gawo lapansi. Kupezeka kokwanira chinyezi kumalimbikitsa zotsatira za hydible, ndikuonetsetsa kuti zikuyenera kukhala ndi mphamvu zolimba.
Kuchuluka kwa kugwirira ntchito: hpmc kumathandizira kugwiritsidwa ntchito kwa cementist yosakaniza, kulola kuyikako bwino ndikuphatikizana. Kupanga koyenera kumachepetsa ntchito ndipo kumatsimikizira kulumikizana kwambiri pakati pa zomatira ndi gawo lapansi, kulimbikitsa mphamvu.
Coutheon: HPMC imagwira ngati yotchinga ndi bander, kukonza couther of Cemion. Kuphatikiza kotsekeka kumachepetsa mwayi wophatikizira ndi magazi, kumabweretsa yunifolomu komanso mawonekedwe ogwirizana.
Kuchepetsa shrinkage: hpmc mumitops mochedwa a shrinement a simenti omwe amachiritsidwa. Kuchepetsa shrazage kumalepheretsa kukula kwa ming'alu pa mawonekedwe a Cound.
Modelion: hpmc amalimbikitsa kutsatira popanga filimu yokhazikika pamtunda wa gawo lapansi. Kanemayu amapereka mawonekedwe ogwirizana ogwirizanitsa ndikusintha mphamvu yonyowa yomatira, kuwongolera bwino.
Kuwongolera Konzekerani Nthawi: HPMC imatha kusintha makonzedwe a Cementist, kulola nthawi yokwanira kuti kugwirizanitsidwa koyenera kuchitika. Mapulogalamu olamulidwa amalepheretsa asanakwane chomatira, kuonetsetsa kukula koyenera.
4.Pappere ndi malingaliro:
Pomanga, HPMC imapeza kugwiritsidwa ntchito kofala pamapulogalamu osiyanasiyana momwe kulimbikira kumafunikira:
Tile zomatira: hpmc nthawi zambiri zimaphatikizidwa mu ma tile omatira tile kuti mukonze mphamvu ndi kugwirira ntchito. Imatsimikizira zomata zodalirika za matailosi m'gawo lapansi, zomwe zimathandizira kulimba komanso kukhala ndi moyo wautali.
Matope ndi kubwereketsa: HPMC imawonjezedwa ndi matope ndikupereka njira zowonjezera kulimbikira mphamvu ndi coutheon. Zimakhala bwino magwiridwe antchito awa pantchito zothandiza monga kupasulira, kubweretsa, ndi zomanga.
Zodzikongoletsera zodzipangitsa: HPMC imathandizira pakugwiritsa ntchito mankhwala odzikongoletsa pokonzanso katundu ndi mphamvu yolumikizana. Imapangitsa kuti yunifolongosokeni yunifolomene ndi kutsatira gawo lapansi, lomwe limapangitsa mosalala komanso level.
Maulanje: HPMC imagwiritsidwa ntchito popanga ma grout kuti apititse patsogolo mphamvu komanso kupewa nkhani zokhudzana ndi shrinkage-zokhudzana. Imakhala bwino yoyenda ndi kugwiritsidwa ntchito kwa ma grout, otsogolera kudzaza mafupa ndi mipata.
Hydroxypropyl methylcellulose (hpmc) amatenga gawo lofunikira pakuwongolera mphamvu yolimbana ndi mphamvu yolimbikitsira madzi, kugwirira ntchito, zotsatsa, ndikuwongolera shrions ndikukhazikitsa nthawi. Malo omwe amasinthasintha kuti ikhale yothandiza pomanga ntchito zosiyanasiyana, kuonetsetsa ubale wolimba komanso wodalirika pakati pa magawo ndi zomatira. Kuzindikira njira zomwe HPMC imathandizira kulimbikira mphamvu ndikofunikira kuti mugwiritse ntchito ndikukwaniritsa zomwe mukufuna pantchito yomanga.
