Hpmc imathandizira kusungidwa kwamadzi kwa zinthu zomanga

M'mapulo amakono, magwiridwe antchito omanga amakonda kwambiri ntchitoyo. Ndi chitukuko cha ukadaulo, zowonjezera ntchito zantchito zaonjezedwa pang'onopang'ono zida zomangira zachikhalidwe kuti zizigwira ntchito bwino. Pakati pawo, hydroxypropyl methylcellulose (hpmc), monga kusintha kofunikira mankhwala, amagwiritsidwa ntchito kwambiri pomanga zida, makamaka pokonza madzi.

Mikhalidwe yoyambira ya HPMC
HPMC ndi ma cellulose omwe sanali mainchesi omwe amapezeka ndi kusinthidwa kwa mankhwala a cellulose, ndi madzi abwino kusiyanasiyana. Imatha kusungunuka mwachangu m'madzi kuti apange madzi owoneka bwino kapena amkaka abwino kwambiri, ndikuyimitsidwa bwino kwambiri, kuyimitsidwa, kulumikizana, emulsization, njira yopanga mafilimu. Makamaka kuchuluka kwake kwa madzi kumapangitsa kuti HPMC ikhale yowonjezera pazowonjezera zomangira.

Udindo wa madzi kusungitsa zinthu zomanga
Kusunga kwamadzi kwa zinthu zomanga kumatanthauza kuthekera kwa zinthu zofunika kusunga chinyontho pakumangidwa, komwe kumakhala ndi njira yofunika kwambiri pakupanga ntchito yomanga. Zipangizo zochokera ku Smentam ndi Gypsum zochokera kumadzi zimafunikira kutengapo gawo pakuchita kwa hydration. Ngati kusungidwa kwamadzi sikokwanira, madziwo adzatayika msanga, akutsogolera pamavuto otsatirawa:

Kugwiritsa ntchito magwiridwe antchito: madzi osefukira mwachangu kwambiri adzapangitsa kuti zinthuzo zitheke, zomwe zimakhudza kuthekera komanso kugwira ntchito pomanga.

Kuchepetsa Mphamvu: Gawo lomwe silinamalizepo ngati ydration zikhalidwe likhala malo ofooka munkhaniyo, potero kuchepetsa mphamvu zonse.

Pamaso: Chifukwa cha kutayika kwa madzi mwachangu, ming'alu yovuta imakonda kupezeka pazinthuzo, zomwe zimakhudza mawonekedwe ake.

Kuphatikizidwa kosakwanira: makamaka pamapulogalamu monga matoma a tiles ndi matope, mphamvu zosakwanira zimatha kumabweretsa mavuto monga kugwa.

Udindo wa hpmc pokonza madzi
Makina osintha magwiridwe antchito am'madzi a HPMC pakumanga zida kumawonekeranso mbali zotsatirazi:

Kupanga filimu yosungira madzi
HPMC itasungunuka m'madzi, imapanga filimu yopumira yamadzi yotsalira pamtunda wa tinthu tating'onoting'ono. Kanemayu amatha kupewa kusintha madzi osinthika mwachangu, pomwe akugawa madzi kuti atsimikizire kukula kopambana kwa zomwe ukuchita.

Kumawonjezera mafayilo a zida
HPMC ili ndi mphamvu yabwino. Itha kuwonjezera mafayilo a osakaniza mu matope kapena kutsuka ndikupanga mawonekedwe amphamvu amphatso. Kapangidwe kameneka kamatha kutseka chinyezi komanso kuchepetsa kuchepa kwa madzi aulere.

Sinthani zinthu za REOgical za zida
Posintha kuchuluka kwa hpmc kuwonjezera, zopangira zomangira zimatha kuthandizidwa kuti azitha kukhalabe ndi mwayi wogwiritsa ntchito kutentha kapena madzi owuma. Izi ndizofunikira kwambiri pomanga chilimwe kapena m'malo owuma.

Sinthani Madzi Kugwiritsa Ntchito Mwaluso
HPMC imatha kuchepetsa kugwedeza kwa zinthu ndikupanga kufalitsa madzi yunifolomu, potero kumawonjezera kuchuluka kwa madzi ndikupewa kuchepetsedwa kwa madzi kapena kuperewera kwa madzi akomweko.

Madera Ogwiritsa Ntchito
Zotsatira za Madzi a HPMC zimapangitsa kuti zigwiritsidwe ntchito kwambiri m'magawo otsatirawa:

Kumamatira: Onetsetsani kuti zomatira sizingalephere chifukwa cha kutaya kwamadzi pomanga ndikusintha molunjika.
Plaster matope: Sinthani zomangamanga ndikuchepetsa ming'alu yochepa.
Pansi pamtunda: Onetsetsani kupita patsogolo kwa momwe mungakhalire ndi vuto la hydrate ndi ming'alu.
Puti ufa wa putty: Sinthani magwiridwe antchito ndi kukhazikika kwa malo osanjikiza.
Zida za gypsum: kupewa kutaya kwamadzi kwambiri ndikuwonjezera magwiridwe ake.
HPMC Moyenerera bwino ntchito zomangamanga ndi mtundu wotsiriza wa zida zamadzi posungiramo madzi osungidwa. Ndi kusintha kosalekeza kwa zofunikira za makampani omanga ntchito, chiyembekezo chogwiritsa ntchito cha HPMC chidzakhala chowonjezera. Kudzera pamapangidwe oyenera ndi kukhathamiritsa kwa kuwonjezera, HPMC singangosintha kusungidwa kwamadzi, komanso kusintha zinthu zina, kuthandiza kukonza bwino ntchito zomanga.
