Kodi HPMC ya gypsum gypsum ndi chiyani?

1 Kuyamba
HPMC (hydroxypypyl methyl cellulose) ndi ma cellulose omwe amagwiritsidwa ntchito kwambiri m'matoto omanga, kuphatikizapo gypsum pulasitala. Monga chowonjezera chofunikira kwambiri, hpmc limakhala bwino pokonzanso katundu ndi mawonekedwe a mapulogalamu a gypsum.

2. Katundu waukulu wa HPMC
HPMC ndi polymer pompound yokhazikitsidwa ndi kusintha kwa mankhwala a cellulose. Zojambula zake zimaphatikizapo:

Kusungunuka kwamadzi: hpmc amatha kusungunuka mwachangu m'madzi ozizira, ndikupanga yankho lomveka bwino kapena pang'ono.
Kukula: kumatha kuwonjezera mafayilo a yankho.
Gulling: HPMC ili ndi katundu wapadera wamafuta, ndipo yankho limayambiranso pambuyo pozizira.
Kusunga kwamadzi: pomanga zida, kumatha kusintha bwino madzi osungirako madzi ndikuwonjezera nthawi yogwira ntchito.
Thuma: Kusintha mafuta am'mimba a zinthuzo kuti athandizire ntchito zomanga ndi ntchito.

3. Udindo wa HPMC mu gypsum plaster
3.1 Sinthani kusungidwa kwamadzi
HPMC imachulukitsa kuchuluka kwa madzi a gypsum gypsum pulasitala ndi kuchepetsa madzi ofulumira. Izi ndizofunikira kwambiri pakumanga kwa pulasitala yama gypsum, monga madzi okwanira zimapangitsa kuti yunifolomenemeza pulasitalayo ndikupewa shrinkage ndi ming'alu.

3.2 Onjenjemera
HPMC imawongolera mgwirizano pakati pa Stucco ndi gawo lapansi. Izi zimathandiza kukonza mphamvu yayikulu ya pulasitala ndipo imalepheretsa kusenda ndi kungotuluka, potero, pokweza moyo wake wa utumiki.

3.3 Sinthani zomangamanga
HPMC imawonjezera mafayilo a pulasitala ya gypsum, ndikupangitsa kuti ikhale yosavuta kuigwiritsa ntchito ndikupanga mawonekedwe osalala. Kuphatikiza apo, HPMC imathandizira kuti mafuta a STCCO, akupangitsa kuti zikhale zosavuta kuti zizigwiritsa ntchito zida zomangira, potero kukonza zolimbitsa thupi ndi zabwino.

3.4 Pewani kusaka
HPMC imasintha kusasinthika ndi chiwerewere cha pulasitala, kupewa pulasitalayo kuti asakwakire ndi kukasaka panthawi yomanga, ndiye kuonetsetsa kusalala kwa khoma.

3.5 Kuchulukitsa maola otseguka
HPMC imawonjezera nthawi yotseguka ya Stucco, kupereka nthawi yomanga yomanga nthawi yochulukirapo kuti muchepetse ndikugwiritsa ntchito zolakwika zopangidwa chifukwa chosowa nthawi.

4. Mlingo ndi Useg of Hopmc
4.1 Mlingo wowongolera
Mu gypsum pulasitala, hpmc nthawi zambiri imawonjezeredwa pamizere pakati pa 0,1% ndi 0,5%. Izi zimatengera mawonekedwe a stucco, kugwiritsa ntchito pulogalamuyi, ndi nyengo. Mlingo womwe umakhala wokwera kwambiri kapena wotsika kwambiri ungakhudze magwiridwe a Stucco, motero kusintha komwe kungafunike kutengera zochitika zenizeni.

4.2 Momwe Mungagwiritsire Ntchito
HPMC iyenera kubalalika kwambiri mu ufa wouma kenako osakanikirana ndi zosakaniza zina. Nthawi zambiri nthawi yokonzekera ya Stucco, HPMC imawonjezeredwa mu ufa wa gypsum wokhazikika, ndiye kuti madzi oyenera amawonjezeredwa, ndipo osakaniza amasakanizidwa mpaka osakanikirana mpaka yunifolomu yosinthira.

5. Ubwino wa HPMC ku Gypsum Plaster
5.1 Chitetezo cha chilengedwe
HPMC ndi mankhwala osazizwitsa, osadetsa. Kugwiritsa kwake ntchito sikungakhale ndi zovuta zachilengedwe, zomwe zikugwirizana ndi chilengedwe choteteza zachilengedwe.

5.2 Chuma
Chifukwa cha kuchuluka kwa HPMC, kuchuluka kwake kumatha kusintha magwiridwe antchito a gypsum, motero kumakhala ndi mtengo waukulu.

5.3 Kukhazikika
Kuchita kwa HPMC mu gypsum pulasitiki kumakhala kokhazikika ndipo sikusintha kwambiri chifukwa cha kusintha kwa kutentha ndi chinyezi. Ndioyenera madera osiyanasiyana omanga.

6. Milandu yothandiza
Mukupanga zenizeni, pulasitala ya gypsmu kuwonjezeka ndi HPMC yagwiritsidwa ntchito kwambiri pamakoma opindika, kupaka utoto, kukonza nyumba ndi minda ina. Mwachitsanzo, mukamapaka utoto wamkati wa nyumba, kuwonjezera HPMC ku gypsum pulasitiki imatha kuteteza ming'alu ndi ufa kutaya zovuta ndikupereka zotsatira zabwino za khoma.

Kugwiritsa ntchito HPMC mu gypsum pulasitiki sikumangowonjezera zinthu zakuthupi, komanso kumathandizanso kukhala omanga komanso kuchita bwino. Kusungidwa kwake kwamadzi apamwamba, zomatira ndi zomangamanga zimapangitsa kuti zikhale zofunikira kwambiri pazomangira zamakono. M'tsogolomu, monga momwe makampani omanga makampani amafunikira kwambiri magwiridwe antchito ambiri, malo ochezeka amawonjezeka, chiyembekezo cha ntchito cha HPMC sichidzakhala chowonjezera.
