Kugwiritsa ntchito hydroxypropyl methylcellulose pazakudya zomanga

Hydroxypylropyl (HPMC) ndi ma cellulose ether ether ether ether ether ether ether ether ether ether ether ether ndikulubwino kwambiri

Kugwiritsa ntchito hydroxypypyl methylcellulose zinthu zomwe zili mmenga ndizofunikira kwambiri. Kuonjezera kuchuluka kwa HPMC yokwanira kwa simenti kumatha kusintha mapangidwe a matope. HPMC ili ndi madzi abwinobwino madzi, zomwe zikutanthauza kuti zitha kuchedwetsa madzi okwanira m'tatayi, potero kuwonetsetsa kuti simenti ndi mphamvu ya matope. Kuphatikiza apo, HPMC imatha kukonzanso nkhanza komanso kukana chisanu matope, kungolola kuti ikhale yolimba kwambiri.

HPMC imagwiritsidwanso ntchito kwambiri mu simenti ya ceramic. Sitame ya matabwa ndi matope apadera omwe amagwiritsidwa ntchito polemba matayala a ceramic, omwe amafunikira kulumikizana bwino komanso kugwira ntchito. Udindo wa HPMC mu sile tanti ya kulemera makamaka: Kuwongolera njira yosungirako madzi sitafika, ndikukonza nthawi yotseguka, ndikuonetsetsa nthawi yokwanira yolumikizirana ndi matayala a ceramite; Kuwongolera magwiridwe antchito a simenti. kumathandizira kukana kwa simenti ndikuonetsetsa kuti nthawi yayitali ya matailosi yanthawiyo itatha.

Kuphatikiza pa matope a sile ndi matastic matope, kugwiritsa ntchito hpmc pomanga sikunganyalanyazidwe. Ma deti omanga ndi zinthu zomwe zimagwiritsidwa ntchito kukhoma ndikukonza, zomwe zimafuna katundu wabwino komanso kulimba. Udindo wa HPMC umakhala makamaka kukonza madzi osungirako madzi ndi kupewa shlizage ndi kuwonongeka kwa dekty pa ntchito yomanga; kukonza mphamvu yakutchinga kuti ithe kutsata pansi molimba; ndi kukonza zomanga za patenthedwe. ntchito, kupangitsa kuti ikhale yosavuta kugwiritsa ntchito komanso yosalala, kukonza bwino ntchito ndi mtundu.

Kugwiritsa ntchito HPMC mu khoma la panja kumachititsansonso. M'khoma la khoma lazosautsa, hpmc limagwiritsidwa ntchito makamaka mu matope ndi kumatope. Kusunga kwamadzi kwa HPMC kungawonetsetse kuti matope anyeziwo sadzalephera kukangana kwawo chifukwa cha madzi omanga, ndikuwonetsetsa mgwirizano pakati pa gulu la bolodi lotchinga ndi khoma; Nthawi yomweyo, hpmc amathanso kusintha zokumba zosokoneza komanso kukana matope zimapangitsa kuti zizikhala zopanda ming'alu komanso kukalamba panthawi yayitali.

Kugwiritsa ntchito HPMC mu zinthu za gypsum ku gypsum ndikofunikanso kutchula. Zipangizo zochokera ku gypsum zimagwiritsidwa ntchito kwambiri mkati mwakokongoletsa khoma komanso kuyambitsa, kufunikira kugwirira ntchito bwino komanso mawonekedwe apamwamba. Udindo wa HPMC muzochitika zama gypsum zimawonekera bwino kukonza madzi osungirako zinthuzo ndikuletsa shrinkage ndi kusokonekera pomanga; Kupititsa patsogolo kugwirizanitsa mphamvu ya zinthuzo kuti ithe kutsatira pansi molimba; ndi kukonza ntchito yomanga nkhaniyo. ntchito, kupangitsa kuti ikhale yosavuta kugwiritsa ntchito komanso yosalala, kukonza njira yopanga ndi zokongoletsera.

Hydroxypropyl methylcellulose ali ndi chiyembekezo chothandiza pantchito zomanga. Imakhala bwino kwambiri ndikugwiritsa ntchito zotsatira za zida pokonza madzi posungira madzi, kugwirira ntchito mphamvu ndi ntchito zomangira zomangamanga zosiyanasiyana. Ndi chitukuko chopitilira muukadaulo chomanga ndi kusinthasintha kwa zomwe mukufuna kuchita zomangira, kugwiritsa ntchito kwa hydroxypropyl kumakhala kochulukirapo ndikusewera gawo lofunikira.
