Hydroxypropyl wowuma ether (HPS)ndicellulose etherKodi ndi zigawo ziwiri zomanga zamankhwala zodziwika bwino, zomwe zimagwiritsidwa ntchito kwambiri pomanga, monga matope, zokutira, zokutira, zopangidwa ndi mankhwala , zotsatira za ntchito, ndi ndalama.
1. Magwero azomera ndi kapangidwe ka mankhwala
Hydroxypropyl wowuma ether (HPS)
HPS imatengera wowuma mwachilengedwe ndikupeza pogwiritsa ntchito kusintha kwa kusintha. Zida zake zamkati ndi chimanga, tirigu, mbatata ndi mbewu zina zachilengedwe. Stiarch manyowa amapangidwa ndi mayunitsi a shuga omwe amalumikizidwa ndi α-1,4-glycosiidic ndi ndalama zochepa za íakulu. Pambuyo hydroxypropropylaty, hydrophilic hydroxypyl.
cellulose ether
Cellulose amachokera ku cellulose wachilengedwe, monga thonje kapena nkhuni. Cellulose amapangidwa ndi mayunitsi a glucose omwe amalumikizidwa ndi β-1,4-glycosidic. Cellulose wamba amaphatikiza hydroxypropyl methylcelulose (hpmc), ma hydylluelyl, ma hydroxethyl amasunthika komanso kukhala ndi mphamvu yamankhwala.
2. Mphamvu zathupi
Machitidwe a ma hpps
Kukula: HPS imakhala yokulirapo, koma poyerekeza ndi ma cellulose ether, luso lake lotukuka limafooka pang'ono.
Kusunga kwamadzi: HPS yasungidwa kwamadzi ndipo ndiyoyenera kutsika kwamitundu yomangidwa.
Kugwira Ntchito: HPS imatha kusintha kugwirira ntchito matope ndikuchepetsa kusamba pomanga.
Kukana kutentha: HPS imaganizira kutentha ndipo imakhudzidwa kwambiri ndi kutentha kozungulira.
Mapangidwe a magwiridwe antchito a celluse
Kukula: cellulose ether imakhala yolimba kwambiri ndipo imatha kuwonjezera matope a matope kapena kufooka.
Kusungidwa kwamadzi: cellulose ether ali ndi madzi abwino osasunga madzi, makamaka mu matope ambiri, omwe amatha kuwonjezera nthawi yotseguka ndi matopewo okwanira.
Kugwira ntchito: ethel ether ndibwino kwambiri kukonzanso kugwirira ntchito komanso kumatha kuchepetsa mavuto moyenera monga kuwonongeka ndi ufa.
Kukana kutentha: Ethel ether ether ali ndi kusintha kwamphamvu kwa kusintha kwa kutentha komanso kusakhazikika.
3. Zotsatira za ntchito
Kugwiritsa NtchitoMabps
Mu matope owuma, mabp amatenga gawo la ntchito yowongolera, kukonza chitetezo chamadzi, ndikuchepetsa kuwonongeka ndi tsankho. Ndizachuma komanso oyenera kugwiritsa ntchito malo okhala ndi mtengo wokwera mtengo, monga momwe amawonongera khoma wamba, pansi matope, ndi zina zambiri.
Kugwiritsa ntchito kwa cellulose ether
Cellulose earsamagwiritsidwa ntchito kwambiri mafoni ambiri ochita masewera olimbitsa thupi, zomata za matabwa, zida zama gypsum-zochokera kunja. Mphamvu zake zapamwamba komanso zosunga madzi zimatha kusintha momwe zimagwiritsidwira ntchito pogwiritsira ntchito komanso kutsutsa kwa zinthuzo, ndipo ndizoyenera makamaka kwa ntchito zomwe zimakhala ndi zovuta zomanga ndi zabwino.
4. Mtengo ndi chilengedwe
mtengo:
HPS ili ndi mtengo wotsika ndipo ndi yoyenera kugwiritsa ntchito pamsika wamtengo wapatali. Cellulose edies ndi okwera mtengo, koma amagwiritsa ntchito bwino kwambiri ndipo ndi okwera mtengo pofunafuna ntchito zomanga.
Chitetezo Chachilengedwe:
Onsewa amachokera ku zinthu zachilengedwe ndipo amakhala ndi zachilengedwe zachilengedwe. Komabe, chifukwa makonzedwe ochepa mankhwala amadyedwa mu ma HPS, katundu wake akhoza kukhala wotsika.
5. Kusankhidwa
Zofunikira: Ngati muli ndi zofunikira zazikulu zokulira ndi madzi osasunga madzi, muyenera kusankha cellulose ether; Za zida zomwe ndizochepa mtengo koma zimafunikira kusintha kwina kwachuma, mutha kuganizira kugwiritsa ntchito HPS.
Zochitika Zogwiritsira Ntchito: Ntchito yomanga kutentha kwambiri, khoma lomata kunja, matayi a tile ndi malo ena omwe amafunikira thandizo lalikulu la ma cellulose; Kwa khoma wamba mkati kapena matope oyambira, HPS imatha kupereka mayankho azachuma komanso othandiza.
Hydroxypropyl wosuta magazindicellulose ether Aliyense ali ndi zabwino zawo ndipo amasewera maudindo osiyanasiyana pomanga zida. Kusankhidwa koyenera kumaganiziridwa mokwanira pazomwe zimachitika, ndalama zowononga, malo omanga ndi zinthu zina mwa polojekiti kuti akwaniritse bwino ntchito.
