3,chilengedwe
Katundu: Izi ndi ufa woyera kapena wopanda ufa, zopanda fungo, zosasangalatsa ndipoosadandaula.
Kuthekera kwamadzi ndikutha kukula: Izi zitha kusungunuka m'madzi ozizira kuti apange yankho lowoneka bwino.
Kusungunuka mu organic sodics: chifukwa ili ndi magulu ena a hydrophobic methoxyl, izi zitha kusungunuka m'malo ena okhazikika, ndipo imatha kusungunuka m'malo ena okhazikika, ndipo amathanso kusungunuka m'malo ena okhazikika, ndipo amathanso kusungunuka m'madzi osakanizidwa ndi madzi ndi zinthu zachilengedwe.
Kutsutsa Mchere: Popeza izi ndi polymer yopanda ionic, imakhala yokhazikika m'matumba achitsulo kapena ma elekiti opanga.
Zochitika Padziko Lonse: Madzi am'madzi a mankhwalawa ali ndi zochitika zapadziko, ndipo amakhala ndi ntchito ndi katundu monga emulsization, oteteza colloid ndi bala.
Miyala yamafuta: pomwe mankhwalawa am'madzi amakonzedwa kutentha, amakhala opaque mpaka kufota, kotero kuti yankho limataya mafayilo. Koma nditazizira, idzatembenukiranso ku yankho loyamba la yankho. Kutentha komwe kuli miyala yamtengo wapatali kumachitika kumatengera mtundu wa malonda, kukhazikika kwa yankho komanso kuchuluka kwa kutentha.
Khalidwe lokhazikika: Makutu am'madzi am'madzi ndi khola mkati mwa ph3.0-11.0.
Zotsatira za Madzi: Popeza izi ndi hydrophilic, zitha kuwonjezedwa ndi matope, gypsum, utoto, etc. Kuti musunge madzi ambiri.
Kusungidwa: Kuyerekezera ndi ma poity osungunuka madzi, njira yothetsera matendawa imakhala ndi zinthu zapadera za ma viscoelastic. Zowonjezera zake zimatha kusunga mawonekedwe a deratimic zinthu zosasintha.
Thuma: Kuchulukitsa malonda kumatha kuchepetsa chiwonetsero champhamvu komanso kulimbitsa thupi mankhwala otalika ndi simenti.
Kapangidwe ka filimu: Izi zimatha kupanga filimu yosinthika, yowoneka bwino ndi katundu wabwino kwambiri, ndipo ali ndi mafuta ndi kupha mafuta
4. Mankhwala ndi mankhwala
Kukula kwa tinthu: Kupitilira kwa maumboni 100 ndi akulu kuposa 98.5%, ma mesh a Mesh Party ndi 100%
Kutentha kwa Carbotion: 280 ~ 300 ℃
Zowoneka bwino: 0.25 ~ 0.70 / CM mphamvu yokweza 1.26 ~ 1.31
Kutentha kochepetsa: 190 ~ 200 ℃
Matendawa: 2% Socious yankho ndi 42 ~ 56dy / cm
Kusungunuka: kusungunuka m'madzi ndi ena ma sol sol, njira yothetsera matendawa imagwira ntchito. Kuwonekera kwambiri. Kugwiritsa ntchito mokhazikika, kusungunuka kumasintha ndi mafakiti, kutsindika kwa mafalo, chachikulucho chosungunuka.
HPMC ilinso ndi mawonekedwe a luso lakumwamba, kukana mchere, kusungunuka kwamadzi, mawonekedwe abwinobwino mafilimu, komanso ma enzyme ophatikizika, ophatikizika.
Zisanu, cholinga chachikulu
HPMC ya mafakitale imagwiritsidwa ntchito ngati obalalitsa popanga polyvinyl chloride, ndipo ndiye wothandizira wothandizira pokonzekera pvc poyimitsidwa. Kuphatikiza apo, itha kugwiritsidwa ntchito ngati thiccener, hitebilifar, emulsifier, mapepala opanga, opanga mafilimu, zodzikongoletsera, zimakhala ndi mawonekedwe a nthawi zonse Ndipo tinthu tomasula, mphamvu yokoka yabwino komanso njira yabwino yopangira gelatin ndi mowa wa polyvinyl ngati osamwazika.
Njira Zisanu ndi chimodzi zokhutha:
(1). Tengani madzi otentha, ayikeni mu chidebe ndikuchitenthe pamwamba pa 80 ° C, ndipo pang'onopang'ono onjezani pang'onopang'ono malondawo pansi pa kusuntha pang'onopang'ono. Cellulose yoyandama kumadzi poyamba, koma pang'onopang'ono amabalalitsidwa kupanga yunifolomu. Njira yothetsera vutoli idakhazikika pomwe mukuyambitsa.
(2). Kapenanso, kutentha 1/3 kapena 2/3 ya madzi otentha kupitirira 85 ° C, onjezani kuchuluka kwa madzi ozizira, pitirizani kusangalatsa, ndikuziziritsa kusakaniza.
(3). Miyala ya cellulose ikhale yabwino, ndipo imakhalapo ngati tinthu tating'onoting'ono tomwe timakhala ndi tinthu tomwe timayambitsa, ndipo imasungunuka mwachangu ikamakumana ndi madzi ofunikira.
(4). Pang'onopang'ono komanso mobwerezabwereza zimawonjezera maselole kutentha kwa firiji, oyambitsa mosalekeza mpaka yankho lowunikiridwa.
