Hydrophobic adasinthidwa hydroxethyl cellulose (Hec) ndi mtundu wa zonyansa za hydrophobic (monga ma alkyl yayitali, ndi zina) ku Hydroxethyl (Hec). Zinthu zamtunduwu zimaphatikiza katundu wa hydrophilic ya hydroxethyl cellulose yokhala ndi magulu a hydrophobic a ma hydrophobic magulu a hydrophobic ndipo amagwiritsidwa ntchito kwambiri pazokutira, zonunkhira, zopangira mankhwala odzola.
1. Njira ya Synthesis ya Hydrophophy Mored hydroxyethyl cellulose
Kaphatikizidwe ka hydrophochoically osinthika hydroxyethyl cellulose nthawi zambiri imachitika ndi njira zotsatirazi:
1.1 Kuchita Kuchita
Njirayi ndikutenga hydroxyethyl cellulose yokhala ndi mankhwala osokoneza bongo (monga mafuta acigololo acids, etc.) kukhazikitsa magulu a hydrophobic mamolekyulu. Kutengera kwassering sikungayambitsenso ma hydrophobic magulu a hydrophobic, komanso kusintha hydrophobicity ndi kukula kwa ma polima. Zochitika za kapangidwe ka kaphatikizidwe, monga kutentha, nthawi, zosungunulira komanso zothandizira komanso zothandizira, zimakhudzanso magwiridwe omaliza.
1.2 Kulowa
Mwanjira imeneyi, gulu la hydroxyl la hydroxethyl cellulose limasinthidwa ndi gulu la hydrophobic (monga alkyl, phenyl, etc.). Ubwino wa njirayi ndikuti kaphatikizidwe kumakhala kofatsa, mawonekedwe a hydrothyl cellulose amatha kusungidwa bwino, ndipo malonda osinthidwa nthawi zambiri amakhala ndi kusungunuka komanso kukulitsa.
1.3 Kukula
Mwa kukopera ndi ena moormemers (monga acrylic acid, acrytet, etc.), polyrophobicity ikhoza kukonzekera. Njirayi imatha kukwaniritsa zowongolera za kukula kwa cellulose posintha kuchuluka kwa monomers osiyanasiyana.
1.4 Kugwiritsa Ntchito
Mitundu ya hydrophobic imakometsedwa ndi kapangidwe ka Hydroxethyl cellulose kuti apange miyala ya hydrophobic kapena magawo. Njira iyi imatha kukulitsa kukhazikika kwa matenthedwe ndi ntchito ya hydrophophhobically osinthika ma hydrocyothyl cellulose, yomwe ndiyoyenera kuti ikhale yofunikira kwambiri.
2. Makina a Thicken of Hydrophofhobully Osinthidwa hydroxyethyl cellulose
Chithandizo cha kukula kwa hydrophorhoid hydroxyethyl cellulose makamaka makamaka ndi izi:
2.1 Kuchulukitsa Kuyanjana
Kukhazikitsidwa kwa magulu a Hydrophobic kumapangitsa kuti mamonakyulu a celluluse, makamaka m'magulu ogwirizana, omwe magulu a Hydrophobic amakonda kuphatikizira pamodzi kuti apange mawonekedwe owoneka bwino. Mphamvu izi zimabweretsa kuwonjezeka kwa mafayilo a yankho, motero akuwonetsa katundu wolimba.
2.2 hydrophilic-hydrophobic kulumikizana
Magulu a hydrophilic (monga hydroxethyl) ndi magulu a hydyl, phenyll, ndi zina. Mu gawo lozama, gawo la hydrophilic limalumikizana mwamphamvu ndi mamolekyulu amadzi, pomwe gawo la hydrophobic limakopa wina ndi mnzake kudzera mu hydrophobic mphamvu, kuwonjezera kuchuluka kwa mamolekyulu ndipo potero akuwonjezera utupi.
2.3 Kupanga mawonekedwe a netiweki ya yankho
Pambuyo kusintha kwa hydrophobic, kapangidwe kake kake kake kake kake kamene kamasinthira, ndikupanga mawonekedwe okwanira atatu. Kapangidwe kaukondechi kumatha kusintha ma visa ndi kukula kwa njira yothetsera vutoli mkati mwa mamolekyulu.
2.4 Yosavuta kupanga mawonekedwe a gel
Chifukwa cha kukhazikitsa ma hydrophobic magulu a hydrophobic, hydrophophecally yosinthidwa hydroxyethyl cellulose ali ndi katundu wabwino. Pansi pa malo oyenera, monga kusintha kwa kutentha, Ph kapena ndende, magulu osinthika amatha kuyambitsa mapangidwe a gel osakaniza mu yankho, ndikuwonetseranso kwa katundu wake.
3. Kugwiritsa ntchito kwa hydrophochochoid virud hydroxyethyl cellulose
Hydrophobic osinthidwa hydroxyethyl cellulose imagwiritsidwa ntchito kwambiri m'minda yambiri ya mafakitale, makamaka munthawi yomwe kusinthana ndi kusintha kwa Rheogiogical ndi kukhazikika kumafunikira:
3.1 Zovala ndi Zojambula
Mu makampani ophatikizira, hyrophophorhoited hydrocyothyl cellulose imatha kusintha minyeyo yazachinyengo, ndikumagwira ntchito yolumikizira madziwo ndi kuthetsa madzi ndi banga.
3.2 Oyeretsa ndi zotchinga
Kuonjezera ma hydrophorthochoidy ydrophyethyl cellulose ku chowonera kumatha kusintha mafayilo a zotsekemera, kupangitsa kuti zikhale zokhazikika komanso zosavuta kuzigwiritsa ntchito.
3.3 zodzikongoletsera
Mu gawo la zodzikongoletsera, hydrophorobhokelly osinthidwa hydroxyethyl cellulose nthawi zambiri imagwiritsidwa ntchito ngati thicliner ndikuyimitsa othandizila, makamaka m'malo ena, mafuta omwe amatha kusintha kapangidwe kake ndi malonda.
3.4 Wonyamula Mankhwala Osokoneza bongo
Chifukwa cha kukula kwake komanso kusasinthika, hydrophophetcally kusinthidwa kwa Hydrothyl cellulose yaphunziridwanso kugwiritsa ntchito mankhwala osokoneza bongo, omwe angayang'anire bwino kumasulidwa kwa mankhwala osokoneza bongo.
Mwa kuyambitsa magulu a hydrophobic, hydrophofhophy mosinthika ma hydroxethyl cellulose samangopatsa ma hydroxethyl cellulose exrose exarch proteriction ntchito zosiyanasiyana. Makina ake okumbika makamaka amatengera kulumikizana pakati pa magulu a hydrophobic ndi magulu a hydrophilic, zotsatira zoyipa ndi kusintha kwa njira yothetsera vuto. Ndi kuyerekezera kwa kafukufuku, kaphatikizidwe ka kaphatikizidwe ndi gawo la ntchito ya hydrophofhobully osinthika ma hydrocyothyl cellulose idzakulitsidwanso, ndi chiyembekezo chamsika.
