1. Kodi alias wa hydroxypypyl ndi chiyani methylcellulose?
- Ananswer: hydroxypropyl methy cellouse, Chingerezi: hydroxypropyl celyl celyl cellose cellose, hpmc kapena mhpc, hypclise; Cellulose hydroxypropyl methy ether; HyPromellose, cellulose, 2-hydroxypropylthyl cellulose ether ether. Cellulose hydroxypropyl methy ether hypoose.
2. Kodi ndi chiyani chofunikira kwambiri cha hydroxypypyl methylcellulose (hpmc)?
- HPMC imagwiritsidwa ntchito kwambiri m'magawo omanga, zokongoletsa, mafinya, mankhwala, chakudya, maulimi, fodya komanso mafakitale ena. HPMC imatha kugawidwa mu kalasi yomanga, chakudya kalasi yam'madzi komanso kalasi yofananira malinga ndi cholinga. Pakadali pano, ambiri mwazinthu zapakhomo ndi kalasi yomanga. Mu kalasi yomanga, putty ufa umagwiritsidwa ntchito pamlingo waukulu, pafupifupi 90% amagwiritsidwa ntchito ngati ufa wa putty, ndipo ena onse amagwiritsidwa ntchito matope a simenti ndi guluu.
3. Pali mitundu ingapo ya hydroxypypyl methylcellulose (hpmc), ndipo kusiyana kwake ndi chiyani?
- Inansder: HPMC imatha kugawidwanso mtundu wa anthu wamba komanso otentha. Mafuta amtundu wa nthawi yomweyo amabalalika mofulumira m'madzi ozizira ndikuzimiririka m'madzi. Pakadali pano, madziwo alibe mafakisoni chifukwa HPMC imangomwazika m'madzi popanda kusinthika kwenikweni. Pafupifupi mphindi ziwiri, mafayilo amadzimadzi pang'onopang'ono amawonjezeka, ndikupanga mafilimu owonekera. Zogulitsa zosungunuka, zikakumana ndi madzi ozizira, zimatha kufalitsa msanga m'madzi otentha ndikuzimiririka m'madzi otentha. Kutentha kukagwa mpaka kutentha kwinakwake, mafayilo amawoneka pang'onopang'ono mpaka apangire cololous wowonekera. Mtundu wosungunuka umatha kugwiritsidwa ntchito mu ufa ndi matope. M'dothi wamadzimadzi ndi utoto, padzakhala gulu lazinthu zomwe sizingagwiritsidwe ntchito. Mtundu wa nthawi yomweyo umakhala ndi ntchito zambiri. Itha kugwiritsidwa ntchito mu ufa ndi matope, komanso guluu wamadzimalo ndi utoto, popanda contacation.
4. Kodi mungasankhe bwanji ma hydroxypyll noth methyllulose (hpmc) pazolinga zosiyanasiyana?
- Chofunika ndikusunga madzi bwino. Kugwiritsa ntchito matope: Zofunikira kwambiri, kuwoneka bwino, 150,000 ndikwabwino. Kugwiritsa ntchito guluu: Zinthu zopota za nthawi yomweyo zokhala ndi mafayilo akulu amafunikira.
5. Kodi tiyenera kuganizira chiyani pakugwiritsa ntchito ubale wapakati pa kukweza ndi kutentha kwa HPMC?
- Inwansder: Makulidwe a HPMC ndi yolingana ndi kutentha, ndiye kuti, mafayilo amawonjezeka ngati kutentha kumachepa. Makutu a chinthu chomwe timakonda kutchula zotsatila za mayeso a 2% am'madzi pa kutentha kwa madigiri 20 Celsius.
Pogwiritsa ntchito, ziyenera kudziwika kuti m'malo omwe ali ndi kutentha kwambiri pakati pa chilimwe pakati pa chilimwe komanso nthawi yachisanu, tikulimbikitsidwa kugwiritsa ntchito mafayilo ocheperako nthawi yozizira, yomwe imathamangira yomanga. Kupanda kutero, kutentha kumakhala kotsika, mamasukidwe a cellulose achulukitsa, ndipo nthawi yomwe akumva kuti yatha.
Mafayilo apakatikati: 75000-100000 makamaka amagwiritsidwa ntchito
Chifukwa: Kusunga kwamadzi
Maonekedwe apamwamba: 150000-200000 amagwiritsidwa ntchito powonjezera polystyrene tinthu toyambitsa ufa wa mphira ndi matope a matope a matope.
Chifukwa: Makulidwewo ndi okwera, matope siophweka kugwa, sag, zomangamanga zimayenda bwino.
6. HPMC ndi gawo lopanda ma celluse, ndiye kuti siayic?
-Answer: Mawu a Sing'anga, osakhala a Ions ndi zinthu zomwe sizimayenda m'madzi. Ma Ionirization amatanthauza njira yomwe electrolyte imasungunuka mu ma masikono omwe amatha kusunthira momasuka mu zosungunulira zina (monga madzi, mowa). Mwachitsanzo, sodium chloride (nacl), mchere womwe timadya tsiku lililonse, umasungunuka m'madzi ndi inozi kuti apange ma ionsuum osinthika komanso oyenda. Ndiye kuti, pamene HPMC imayikidwa m'madzi, sizingasungunuke mu ma ions, koma kukhalapo mawonekedwe a mamolekyulu.
