HPMC ndi HEMC pantchito yomanga

HPMC ndi HEMC ali ndi maudindo ofanana muzomangamanga.Itha kugwiritsidwa ntchito ngati dispersant, wothandizila madzi posungira, thickening wothandizila ndi binder, etc. Iwo makamaka ntchito simenti matope ndi akamaumba mankhwala gypsum.Izo ntchito simenti matope kuonjezera adhesion ake, workability, kuchepetsa flocculation, kusintha mamasukidwe akayendedwe ndi shrinkage, komanso kusunga madzi, kuchepetsa kutaya madzi pa konkire pamwamba, kulimbitsa mphamvu, kupewa ming'alu ndi weathering mchere madzi sungunuka, etc. Amagwiritsidwa ntchito kwambiri mu pulasitala, gypsum pulasitala, gypsum mankhwala, matope matope, pepala caulking, wothandizila caulking, matailosi zomatira, kudziona-leveling pansi zinthu, etc. Angagwiritsidwe ntchito ngati filimu kupanga wothandizira, thickener, emulsifier ndi stabilizer mu zokutira emulsion ndi zokutira madzi sungunuka utomoni, kupereka filimu zabwino abrasion kukana, kufanana ndi adhesion, ndi kupititsa patsogolo mavuto, kukhazikika kwa zidulo ndi zapansi ndi ngakhale ndi zitsulo inki.Chifukwa cha kukhazikika kwake kosungirako bwino kwa viscosity, ndizoyenera makamaka ngati dispersant mu zokutira za emulsified.M'mawu amodzi, ngakhale ndalama zomwe zili mu dongosololi ndizochepa, ndizothandiza kwambiri komanso zimagwiritsidwa ntchito kwambiri.

Kutentha kwa gel osakaniza a cellulose ether kumatsimikizira kukhazikika kwake kwamafuta pamagwiritsidwe ntchito.kutentha kwa gel osakaniza HPMC nthawi zambiri kumachokera ku 60 ° C mpaka 75 ° C, malingana ndi mtundu, zomwe zili m'magulu, njira zosiyanasiyana zopangira opanga osiyanasiyana, etc. 80°C.Choncho, kukhazikika kwake pansi pa kutentha kwakukulu ndipamwamba kuposa HPMC.Mwachizoloŵezi, pansi pa malo otentha kwambiri omanga m'chilimwe, kusungirako madzi kwa HEMC mumatope osakaniza onyowa omwe ali ndi mamasukidwe ofanana ndi dosing ali ndi mwayi waukulu kuposa HPMC.

Ma cellulose ether ambiri mumakampani omanga ku China akadali makamaka HPMC, popeza ali ndi mitundu yambiri komanso mitengo yotsika, ndipo amatha kusankhidwa mwaufulu pamtengo wokwanira.Pakukula kwa msika womanga m'nyumba, makamaka kuwonjezeka kwa zomangamanga zamakina komanso kuwongolera zofunikira pakumanga, kugwiritsidwa ntchito kwa HPMC pantchito yomanga kupitilira kukula.
