Mafotokozedwe Akatundu:
Hydroxypropyl Methylcellulose (HPMC) ndi ufa woyera wopanda fungo, wopanda poizoni. Pambuyo mokwanira kusungunuka m'madzi, izo kupanga mandala viscous njira. Ndi ether yosakhala ionic cellulose yopangidwa kuchokera ku zinthu zachilengedwe za polima kudzera mumndandanda wamankhwala. Lili ndi makhalidwe a thickening, adhesion, kubalalitsidwa, emulsification, filimu mapangidwe, kuyimitsidwa, adsorption, gelation, pamwamba ntchito, kusunga chinyezi ndi kuteteza colloids.
Ntchito:
Kusungunuka kwamadzi ndi kuthekera kokulirakulira: kumatha kusungunuka m'madzi ozizira, ndikupanga njira yowonekera yowonekera.
Kusungunuka mu zosungunulira organic: Chifukwa lili ndi kuchuluka kwa magulu a hydrophobic methoxy, mankhwalawa amatha kusungunuka muzosungunulira zina.
Kukhazikika kwa mtengo wa PH: Kukhuthala kwa njira yamadzi ya HPMC ndi yokhazikika pamtengo wa PH 3.0-11.0.
Zochita zapamtunda: Yankho lamadzi la HPMC lili ndi zochitika zapamtunda. Imakhala ndi emulsifying effect, imateteza luso la colloid ndi kukhazikika kwachibale.
Kutentha kwa kutentha: Kukatenthedwa pamwamba pa kutentha kwina, njira yamadzimadzi ya HPMC imatha kukhala opaque, kupanga mvula, ndi kutaya kukhuthala. Komabe, idasintha pang'onopang'ono kukhala yankho loyambirira pambuyo pozizira.
Phulusa lochepa: HPMC siionic, imatha kutsukidwa ndi madzi otentha panthawi yokonzekera ndikuyengedwa bwino, kotero kuti phulusa lake ndi lochepa kwambiri.
Kukaniza mchere: Popeza mankhwalawa ndi electrolyte yosakhala ionic komanso yopanda polymeric, imakhala yokhazikika muzitsulo zamadzi zamchere zamchere kapena organic electrolytes.
Mphamvu yosungira madzi: Chifukwa HPMC ndi hydrophilic ndipo yankho lake lamadzi ndi lowoneka bwino. Ikhoza kuwonjezeredwa ku matope, gypsum, utoto, ndi zina zotero kuti zikhalebe ndi madzi osungiramo zinthu.
Kulimbana ndi mildew: Imakhala ndi kukana kwabwino kwa mildew, ndipo imakhala ndi kukhazikika kwa viscosity pakusungidwa kwa nthawi yayitali.
Lubricity: Kuwonjezera HPMC kumatha kuchepetsa mikangano ndikuwonjezera kukhathamiritsa kwa zinthu zadothi zopangidwa ndi ceramic ndi zinthu za simenti.
Katundu wopangira filimu: Imatha kupanga ma flakes amphamvu, osinthika, owoneka bwino okhala ndi mafuta abwino komanso kukana kwa ester.
Pazomangamanga, cellulose ya HPMC itha kugwiritsidwa ntchito ngati chosungira madzi ndikubwezeretsanso matope a simenti kuti matopewo azipopa.
Monga zomatira, kugwiritsa ntchito HPMC mu pulasitala, gypsum, putty ufa kapena zinthu zina zomangira zimatha kukulitsa kufalikira kwawo ndikutalikitsa nthawi yawo yogwira ntchito.
Kusungidwa kwake kwamadzi kumatha kulepheretsa phala kuti lisaphwanyike mwachangu pambuyo pakupaka, komanso kumapangitsanso kulimba kwa zokutira pambuyo poumitsa.
Kupatula apo, mankhwala a HPMC atha kugwiritsidwanso ntchito ngati chowonjezera cholumikizira matailosi, nsangalabwi, ndi zokongoletsera zapulasitiki pantchito yomanga.
Kuphatikiza apo, ufa wa HPMC umagwiritsidwa ntchito ngati thickener, stabilizer, emulsifier, excipient, and water retention agent popanga mafakitale ena, monga petrochemicals, zokutira, zomangira, zochotsa utoto, mankhwala aulimi, inki, kusindikiza nsalu ndi utoto, ceramics, papermaking, cosmetics, etc.
Phukusi: 25 kgs / thumba kapena momwe mukufunira.
Kusungirako: Sungani pamalo opumira mpweya, owuma.
Miyezo yochitidwa: International Standards.
