Mafotokozedwe Akatundu
Hydroxypropyl Methyl Cellulose Etha LK70M ndi chowonjezera chamitundumitundu chosakanikirana chokonzekera komansoyouma-kusakanizamankhwala. Ndiwothandiza kwambiri posungira madzi,thickener, stabilizer, zomatira, filimu kupanga wothandizira muzomangira.
Kampani ya Longou ndiyo ikutsogoleraWopanga HPMCku China ndi 15 yaers experience. Ndi gulu la akatswiri ogulitsa ndi injiniya waukadaulo, Longou'sdry Mix matope zinazatumizidwa kumayiko ochulukirachulukira padziko lapansi.

FAQS
Hydroxypropyl methylcellulose (HPMC) ndi ma cellulose ether omwe ali ndi magulu a hydroxyl pa unyolo wa cellulose m'malo mwa methoxy kapena hydroxypropyl gulu.It amapangidwa ndi etherification wapadera kwambiri koyera thonje mapadi pansi zinthu zamchere. M'zaka zaposachedwa, HPMC, monga chophatikizira chogwira ntchito, imasewera kwambirismu kusunga madzi ndi thickening mu ntchito yomanga ndipo chimagwiritsidwa ntchito mudrymix matope, monga zomatira matailosi, grouts, pulasitala, khoma putty, self leveling, insulation matope ndi etc.
Nthawi zambiri, kwa putty ufa, kukhuthala kwaMtengo wa HPMCndi zokwanira pa 70,000 mpaka 80,000. Cholinga chachikulu ndikusunga madzi ake, pomwe kukhuthala kwake kumakhala kochepa. Kwa matope, zofunikira zaMtengo wa HPMCndi apamwamba, ndipo mamasukidwe akayendedwe ayenera kukhala mozungulira 150,000, amene angatsimikizire kuti ntchito bwino mu matope simenti. Zoonadi, mu ufa wa putty, malinga ngati ntchito yosungira madzi ya HPMC ndi yabwino, ngakhale kukhuthala kuli kochepa (70,000 mpaka 80,000), ndikovomerezeka. Komabe, mumatope a simenti, ndi bwino kusankha HPMC yokhala ndi kukhuthala kwakukulu (kuposa 100,000), chifukwa zotsatira zake zosungira madzi ndizofunika kwambiri panthawiyi.
Vuto la kuchotsa ufa wa putty makamaka limadalira ubwino wa calcium hydroxide ndipo alibe chochita ndi HPMC. Ngati kashiamu wa calcium hydroxide ndi wotsika kapena chiŵerengero cha CaO ndi Ca(OH)2 sichiyenera, chingayambitse putty powder kugwa. Ponena za momwe HPMC imakhudzira, imawonekera makamaka pakusunga madzi. Ngati ntchito yosungira madzi ya HPMC ndi yosauka, ikhozanso kukhala ndi zotsatira zina pa kutaya kwa ufa wa putty.
Zofunikira pakugwiritsa ntchito putty powder ndizochepa. Kukhuthala kwa 100,000 ndikokwanira. Chofunika ndi kukhala ndi makhalidwe abwino osungira madzi. Pankhani ya matope, zofunikira ndizokwera kwambiri komanso kukhuthala kwapamwamba kumafunika, ndipo mankhwala 150,000 amakhala ndi zotsatira zabwino.
