Kugwiritsa ntchito HPMC mumitundu yopitira

Ndi kusintha kosalekeza konzekerani zofunikira zoteteza mphamvu, zida zotchinga ndi gawo lofunikira kumanga makhoma akunja, pansi ndi ziwalo zawo, ndipo magwiridwe awo amakhudzanso mphamvu ya nyumbayo. M'zaka zaposachedwa, ndikukula kwa matekinoloje okhazikika, ofufuza ndi opanga apitiliza kufufuza zinthu zatsopano zamagetsi ndi njira zawo zosinthira. Pakati pawo, hydroxypropyl methylcellulose (hpmc, hydroxypropyl), ngati cellulose yosungunuka yamadzi, kusungunuka, kusungunuka kwamadzi ndi zinthu zotsatsa. , makamaka m'minda ya kunja kwa khoma la zisudzo, matope owuma, zokumba ndi minda ina.

1.CICCRICS ya HPMC

HPMC ndi ma cellulose omwe amapezeka ndi kusintha kwa mankhwala kwa cellulose. Zinthu zake zazikulu zimaphatikizapo:
Kusungunuka kwamadzi: hpmc imatha kupanga njira yolumikizira cololonel m'madzi ndi madzi abwino ndikubalalitsa.
Kukula: ili ndi kukula kwakukulu ndipo kumatha kuwonjezera mamasukidwe amadzimadzi amamwa ngakhale pamankhwala otsika.
Katundu wopanga makanema: hpmc amatha kupanga filimu yopyapyala pamwamba pa gawo la gawo lapansi kuti muchepetse zotsatsa za kusokonekera.
Kusungidwa kwamadzi: Chimakhala chisungiko chamadzi, chomwe chimalepheretsa kusakhazikika kwa madzi ndikuwonjezera nthawi yomanga.
Kusintha: Posintha kapangidwe ka HPMC, kusungunuka kwake kususuka, mamasukidwe ndi zinthu zina zitha kusintha kuti zikwaniritse zosowa zamitundu yosiyanasiyana.
Makhalidwe apaderawa amapereka chiyembekezo cha HPMC chokhacho chogwiritsira ntchito zida zotupa.

2. The Udindo wa HPMC mu magetsi opindika

Kupititsa patsogolo kulumikizana ndi kutsatsa
M'koma kwa khoma la zitsamba, hpmc monga bangal imatha kukonza kwambiri chotsatira pakati pa zisonyezo ndi khoma lapansi. Kutsatira zinthu zotupa zachikhalidwe monga Board Board (EPSS) ndi bolodi ya Polystyrene nthawi zambiri imakhudzidwa ndi zinthu zakunja, monga kusintha kwa chinyezi komanso kutentha kwa kutentha. Mwa kulimbitsa zitsulo za matope kapena zomatira, hpmc imatha kukonza bwino mphamvu pakati pa zotchinga ndi malo osanjikiza monga kusokonekera kwa nyumbayo.

Sinthani Kugwirizana
Kuchita zomangamanga kwa zinthu zotchinga kumagwirizana mwachindunji ndi luso lopanga ndi zotsatira zake. HPMC imatha kusintha magwiridwe antchito, perekani madzi abwino ndi kugwiritsidwa ntchito mogwirizana, kuchepetsa kukana ntchito zomangamanga. Mwachitsanzo.

Sinthani magwiridwe antchito
HPMC ili ndi madzi abwinobwino madzi, omwe amatha kuchedwetsa madzi, kulola kuti zinthu zikhale zotetezeka kwa nthawi yayitali, potengera kulimbikitsa mphamvu yokhala ndi gawo lapansi ndikupewa kuyanika ndi kusweka. Katunduyu ndi wofunikira makamaka m'magawo ozizira ozizira, chifukwa matope amatha kukulitsa mgwirizano wake nthawi youmitsa kutentha pang'ono.

Wopanda madzi ndi anting-ukalamba
Popita nthawi, zokongoletsera zimatha kuwululidwa ndi chinyezi komanso kuwala kwa UV, kumayambitsa kuchepa kwa magwiridwe antchito. HPMC ili ndi ntchito zina zakuthupi komanso zotsutsana ndi ukalamba ndipo zimatha kusintha nyengo ndi kukana zinthu zotuwa. Powonjezera kuchuluka kwa HPMC yoyenera, kukana madzi kusokonekera kungakulitsidwe, kupewetsa kusokonezeka kwa madzi oyamwa ndi kutupa, ndikuwonetsetsa kuti kumasunga magwiridwe antchito kwa nthawi yayitali.

Sinthani Kukhazikika kwa Mafuta
Mapangidwe a HPMC ali ndi hydroxypyl ndi magulu a methyl, omwe amapereka mphamvu yamafuta. M'malo okwera kwambiri, kutentha kwambiri, hpmc kumatha kukhalabe ndi kapangidwe kake ndipo sikumasungidwa mosavuta, kupewa kusintha kwakukulu pakugwiritsa ntchito zotchinga zomwe zimachitika chifukwa cha kutentha. Chifukwa chake, m'mafutukuka ena okonda kutentha kwambiri, malo owonjezera, kuwonjezera kwa HPMC kumathandizira kukhalabe kukhazikika kwa magwiridwe antchito amafuta.

Zitsanzo za HPMC mu majeremusi osokoneza bongo

Makina Opanda Manja
Mu khoma lakumaso, hpmc nthawi zambiri limagwiritsidwa ntchito limodzi ndi zina zowonjezera (monga simenti, gypsum, etc.). Ntchito yake yayikulu ndikuwonjezera chipilala ndi madzimadzi, kusintha chotsatira pakati pa khoma lakunja, ndikuchepetsa mavuto chifukwa cha kusamvana ndi kuwonongeka kwa kutentha ndi mphepo komanso kutentha kwamvula.

Kunja kwa khoma kumangirira
HPMC imagwiritsidwanso ntchito kwambiri mu khoma lakunja. Khoma lakunja limafunikira kukhala ndi chotsatsa chabwino komanso katundu wabwino wopanga mafilimu. HPMC imatha kukonza bwino kufanana, kutsatira ndi kuthirira madzi kukana zokutira, kuonetsetsa kukhazikika kwakanthawi kokhala ndi chitolirocho komanso osakhudzidwa ndi chilengedwe.

matope owuma
Matope owuma ndi zinthu wamba zokopa. Powonjezera hpmc, sizingangosintha chipanduko cha matope, komanso kusintha kusungidwa kwa chinyezi pomanga, ndikuwonjezera ntchito ya opareshoni, ndikuwongolera kugwiritsidwa ntchito kwa matope. Makamaka pamizere yotsika mtengo, kugwiritsa ntchito madzi ku HPMC kumatsimikizira kuti matope abwino.

Kugwiritsa ntchito HPMC mu magetsi opitira kumakhala ndi kusintha kwamphamvu. Mwa kusinthana modetsa, kukonza mgwirizano, kukonza magwiridwe antchito, katundu wopanda madzi, hpmc amatha kusintha moyo wawo wonse, ndikuwonjezera moyo wawo wogwiritsa ntchito mphamvu. Monga zofunika pomanga zachilengedwe kuti chitetezero ndi mphamvu kutengedwa kuti ziwonjezeke, HPMC ili ndi chiyembekezo chothandiza pantchito zamagetsi ndipo ndizoyenera kufufuzanso ndikupanga.
