HPC
Iselulosi yeHPC Hydroxypropyl
ukwaziswa kwemveliso
I-Hydroxypropyl Cellulose (i-Hydroxypropyl cellulose) i-ether ye-cellulose engekho i-ionic ebonakala njengomgubo omhlophe okanye omhlophe.
iimpawu zemveliso
Ukunyibilika kwamanzi okugqwesileyo: inokunyibilika ngokukhawuleza emanzini abandayo ukwenza isisombululo esicacileyo nesizinzileyo.
Uzinzo oluhle lwe-thermal: isenokugcina ukusebenza kwayo okuzinzileyo kumaqondo obushushu aphezulu.
Umsebenzi womphezulu: Unomsebenzi othile womphezulu, unokuphucula ukusebenza kojongano.
Ukwenziwa kakuhle kwefilimu: Umboniso bhanyabhanya owenziweyo uqinile, uyabonakala kwaye unomoya olungileyo.
Ukuhambelana okubanzi: iyahambelana neentlobo ezahlukeneyo zezinto eziphilayo kunye ne-inorganic compounds.
ukusetyenziswa kwemveliso
Umzi-mveliso wamachiza: Njengento yokuncamathelisa kunye nefilimu yokugquma iitafile, isenokusetyenziswa ukwenza amalungiselelo okukhutshwa kancinci.
Ngokomzekelo, kwezinye iipilisi ezikhutshwa ngokuqhubekayo, isantya sokukhululwa kweyeza silawulwa ukuphucula ukusebenza kakuhle.
Izithambiso: Isetyenziswa kwizinto zokuthambisa, iikhrimu kunye nezinye iimveliso ukwandisa ukuhambelana nokuzinza.
Ishishini lokutya: njenge-ejenti yokuqina, i-emulsifier kunye ne-stabilizer, ukuphucula ukuthungwa kunye nencasa yokutya.
Njengakwi-ayisikrimu, ukuyenza ithambile kwaye igudileyo.
Izinto zokwakha: unokuphucula ukubambelela kunye nokusebenza kokwakhiwa kodaka, i-putty, njl.
Inkqubo yokuvelisa
Ngokuqhelekileyo yenziwe kwi-cellulose kunye nepropylene oxide nge-etherification phantsi kweemeko ze-alkaline.
Amathemba emarike
Ngokunyuka kwemfuno yemathiriyeli ekrwada ekumgangatho ophezulu kumashishini ahlukeneyo, iHydroxypropyl Cellulose inentengiso ethembisayo. Iqhutywa yimigangatho engqongqo kwicandelo lamachiza kunye nophuhliso lobuchule kwizinto zokuthambisa kunye namashishini okutya, imfuno yayo yentengiso iyaqhubeka nokukhula.
sebenzisa izilumkiso
Ukugcinwa kufuneka kubekwe kwindawo eyomileyo, enomoya, ugweme umswakama kunye nokushisa okuphezulu.
Xa inyibilikiswa, kufuneka yongezwe kancinci kwaye ishukunyiswe ukuqinisekisa ukunyibilika okupheleleyo kwaye unqande i-agglomeration.
Ngokweemeko ezahlukeneyo zesicelo kunye nokuqulunqwa, uhlengahlengiso olufanelekileyo lwemali eyongezelelweyo ukufezekisa umphumo ongcono.
Ngamafutshane, i-Hydroxypropyl Cellulose idlala indima ebalulekileyo kwiinkalo ezininzi ngenxa yeempawu zayo ezintle, inikezela ngenkxaso eqinile yokuphucula umgangatho kunye nokusebenza kakuhle kweemveliso ezinxulumene nazo.
