HPMC ndi hemc pomanga

HPMC (hydroxypypyl methy cellose) ndi hemc (hydroxy ethyl ethyl ethyl ethyl ethyl ethyl ethyl celyose) ndi celloulose cellose) ndizomwe zimagwiritsidwa ntchito pomanga chifukwa cha zinthu zomanga chifukwa cha zinthu zawo zapadera. Ndi osungunuka madzi osungunuka madzi kuchokera ku cellulose, polymer wachilengedwe amapezeka mu khoma la maselo. HPMC ndi hemc imagwiritsidwa ntchito ngati zowonjezera mu zinthu zosiyanasiyana zomanga kuti zikuwonjezereka katundu wawo ndikusintha kusamala.

Izi ndi zina ndi zina za HPMC ndi hemc pomanga:

Tile zomata za Tile: HPMC ndi hemc nthawi zambiri zimawonjezeredwa ku ma tile omatira kusokonekera komanso kulimba mtima. Olemba ma poizoni amagwira ntchito ngati okuzira, kupereka bwino nthawi yotseguka (motalika kumakhala kothandiza) ndikuchepetsa kusamba kwa tale. Amalimbikitsanso kutsatira kwa omatira ku magawo osiyanasiyana.

CE CECEARARS: HPMC ndi hemc imagwiritsidwa ntchito m'malaya monga ma pusterters, mapepala ndi otuwa akunja amaliza makina (magwiritsidwe). Ma Polity awa amathandizira kugwiritsidwa ntchito kwa matope, kupangitsa kuti ikhale yosavuta kufalitsa ndikulemba. Amakulitsanso coutheon, amachepetsa mathithi amadzi ndikusintha chitsando cha mankhusu a magawo osiyanasiyana.

Zogulitsa zama gypsum: hpmc ndi hemc zimagwiritsidwa ntchito pazolinga zochokera ku gypsum monga propsum plasisters, mankhwala ophatikizika ndi magonedwe okha. Amakhala ngati othandizira osunga madzi, kukonzanso kugwirira ntchito komanso kupitirira nthawi yokhazikitsa zinthu. Ma polimawa amathandiziranso kukana kusokonekera, kuchepetsa shrinkage ndikusintha.

Zodzikongoletsera zodzipangitsa: HPMC ndi hemc zimawonjezeredwa kuti zizikonza zodzipangira nokha kuti ziziyenda bwino komanso kukonza katundu. Ma polity awa amathandiza kuchepetsa mamasukidwe, kuwongolera mayamwidwe amadzi ndikupanga bwino. Amakulitsanso chotsatira cha cholumikizira ndi gawo lapansi.

Kufuula: hpmc ndi hemc kungagwiritsidwe ntchito polumikizirana ndi zomangamanga. Amakhala ngati rheology osintha, kukonza mayendedwe ndi kugwiritsidwa ntchito kwa zopukutira. Ma polimawa amachepetsa kulowa m'madzi, kukonza zotsatsa komanso kuthandizira kukana.

Ponseponse, hpmc ndi hemc amagwiritsidwa ntchito kwambiri pomanga chifukwa cha kuthekera kwawo kosintha, kutsatira madzi osungirako zinthu. Amalimbikitsa zizolowezi zabwino mwa kusintha kulimba komanso mtundu wina wopanga.
