Kusakaniza kosaya, komwe kumathandizira kukonza matope osakanikirana, maakaunti oposa 40% yazomwe zimawononga matope osakanikirana. Ambiri mwa akwatiwe pamsika wapabanja amaperekedwa ndi opanga zakunja, ndipo kuchuluka kwa zinthuzo kumaperekedwanso ndi othandizira. Mtengo wazogulitsa matope owuma umakhala chifukwa chake, ndipo nkovuta kutchula matonge omanga ndi kuyika matope ndi kuchuluka kwakukulu komanso osiyanasiyana. Zogulitsa pamsika wokwera kwambiri zimayendetsedwa ndi makampani akunja, ndipo opanga matope owuma amakhala ndi phindu lochepa komanso ndalama zotsika mtengo; Kugwiritsa ntchito ma adminixtops alibe chidwi komanso kuwunikira, ndikutsatira mwadzidzidzi njira zakunja. Apa, zomwe timagawana nanu ndichakuti gawo la hydroypypyl methylcelluloulose mu matope wamba osakanikirana?
Hydroxypropyll methylclulose ndi mitundu ya cellulose yomwe zotsatira zake ndi zochulukirapo zakhala zikuwonjezeka mwachangu m'zaka zaposachedwa. Hydroxypylropyl amapangidwa ndi thonje loyengeka pambuyo poti mankhwala okwanira a alkizizetion, pogwiritsa ntchito ma proirihide oxude ngati ma cellulose osakaniza ether opangidwa kudzera munthawi zingapo. Mulingo wazolowa m'malo mwake 1.2 ~ 2.0. Katundu wake ndi wosiyana kwambiri kutengera kuchuluka kwa methoxyl zomwe zili ndi hydroxypropyl. Makhalidwe a hydroxypropyll methylcelulose ndi motere:
1. Hydroxypropyll methylcellulose imasungunuka mosavuta m'madzi ozizira, ndipo imakumana ndi zovuta pakusungunuka m'madzi otentha. Koma kutentha kwake kwamadzi otentha kumakhala kokulirapo kuposa kwa methyl cellulose. Kusungunuka m'madzi ozizira kumathandizanso kwambiri poyerekeza ndi methyl cellulose.
2. Makulidwe a hydroxypropyll methylcellulose akukhudzana ndi kulemera kwake. Chokulirapo kunenepa kwambiri, mawonekedwe apamwamba. Kutentha kumakhudzanso mamasukidwe awo, pamene kutentha kumakulirakulira, ma virucy amachepetsa. Komabe, kukopa kwa ma vinyato ake okwera komanso kutentha kwake ndikotsika kuposa kwa methyl cellulose. Njira yake imakhala yokhazikika ikasungidwa kutentha.
3. Kusunga kwamadzi kwa hydroxypropyl kumatengera kuchuluka kwake, ma viccect, ndi madzi osunga madzi pansi pa kuchuluka kwa methyl cellulose.
4. Hydroxypropyll Methylcellulose ndi yokhazikika kwa asidi ndi alkali, ndipo yankho lake la madzi ndi lokhazikika mu pH = 2 ~ 12. Diasc Soda ndi madzi a laimu samagwira ntchito pang'ono pa ntchito yake, koma alkali amatha kufulumizitsa kufalikira kwake ndikuwonjezera pang'ono ma visni. Hydroxypylropyl ndi chokhazikika pamchere wambiri, koma pamene kuchuluka kwa mchere ndi yayitali, mamasukidwe a hydroxypropyl so methylcellulose yankho limayamba kuchuluka.
5. Hydroxypropyll methylcelulose imatha kusakanikirana ndi ma poity-soublers kuti apange yunifolomu komanso njira yapamwamba kwambiri. Monga mowa wa mulyvinyl, madzi owuma, masamba chingamu, etc.
6. Hydroxypropyll methylcellulose ili ndi enzyme yolimba kuposa methylcellulose, komanso kuthekera kwa enzymatic kuwonongeka kwa yankho lake ndilotsika kuposa la methylcellulose.
7. Khoti la Hydroxypypyll Methylcellulose kuti zomanga mtembo ndipamwamba kuposa za methylcellulose.
