Yintoni iHydroxypropyl cellulose CAS 9004-64-2?

I-Hydroxypropyl Cellulose (HPC) CAS 9004-64-2 yi-nonionic cellulose ether eyenziwe ngokuphendula i-cellulose yendalo nge-propylene oxide emva kwe-alkalization.

IHydroxypropyl Cellulose (HPC) yipolymer ye-nonion cellulose ether efunyenwe ngokuguqulwa kweekhemikhali ze-cellulose yendalo. Ngenxa yokungeniswa kweqela le-hydroxypropyl (-OCH₂CH (OH) CH₃) kwisakhiwo sayo se-molecular, iHydroxypropyl Cellulose iyanyibilika emanzini, ibumba ifilimu kwaye ibumba i-thermogel, kwaye i-hydroxypropyl cellulose isetyenziswa njengesongezelelo esisebenzayo kwicandelo lezonyango, ukutya kunye neekhemikhali zemihla ngemihla.

Isicelo

1. Intsimi yamayeza (intsimi esetyenziswa kakhulu, kufuneka ihambelane nemigangatho yomgangatho wamayeza, efana ne-USP, EP, CP)

Izinto ezincedisayo kwifomu yedosi eqinileyo yomlomo

I-Binder: I-Hydroxypropyl Cellulose HPC isetyenziswa kwinkqubo ye-granulation yeepilisi kunye nee-capsules (umzekelo, kwi-granulation emanzi, isisombululo samanzi se-1% ukuya kwi-5% HPC sisetyenziswa njenge-binder ukuphucula ukugeleza kunye nobunzima bee-granules kunye nokunciphisa ukulibaziseka kokuqhekeka kwethebhulethi).

I-Disintegrant: I-HPC yokutshintsha inqanaba eliphantsi (inqanaba lokutshintsha i-0.2-0.4), ngenxa yomxholo wayo ophezulu wamaqela e-hydroxyl angena-ther, ineempawu zokudumba ezinamandla emva kokufunxa amanzi kwaye ingasetyenziswa njenge-disintegrant yeepilisi (umthamo we-2% - 5%).

Izinto zokugquma: I-Hydroxypropyl cellulose kwiipilisi. Isisombululo se-ethanol se-HPC (5% - 10%) sisetyenziselwa iifilimu zokugquma iipilisi ukwenza ifilimu ekhuselayo ebonakalayo, egquma incasa ekrakra yeziyobisi, iphucula uzinzo, kwaye ayichaphazeli ukubola.

Izinto ezisetyenziswa kwi-skeleton ekhutshwa rhoqo: I-HPC enobukrakra obuphezulu ingasetyenziswa njenge-skeleton matrix yeepilisi ezikhutshwa rhoqo (ene-dosage ye-20% ukuya kwi-50%), kwaye izinga lokukhululwa kwamayeza lilawulwa lizinga lokunyibilika kwe-HPC gel layer, nto leyo efikelela ekukhutshweni okuhlala ixesha elide iiyure ezili-12 ukuya kwezingama-24.

Izinto ezincedisayo kwi-topical

I-Hydroxypropyl Cellulose HPC isetyenziswa kumathontsi eliso, iijeli kunye namafutha okugcoba njengesithambisi (ukulungisa i-viscosity yokulungiselela kunye nokwandisa ixesha lokuhlala kwesiyobisi kwindawo yokusebenza) kunye nesiqinisi (ukuthintela ukugaleleka kwamasuntswana esiyobisi).

2. I-Hydroxypropyl cellulose ekutyeni (kufuneka ihambelane nemigangatho yokutya, efana ne-FDA, GB 2760)

Iiarhente zokuqina kunye neziqinisi

IHydroxypropyl Cellulose HPC isetyenziswa kwiziselo (ezifana neziselo zebhaktheriya ye-lactic acid, iijusi zeziqhamo), i-ayisikhrim, kunye neejam ukuphucula i-viscosity yemveliso, ukuphucula ubume bayo (njengobucoselelo be-ayisikhrim), kunye nokuthintela ukuqhekeka okanye ukwahlukana kwamanzi (umlinganiselo: 0.1% ukuya kwi-1.0%).

Iarhente yokwenza ifilimu

I-Hydroxypropyl Cellulose HPC isetyenziswa kwi "edible cling film" yeziqhamo nemifuno (isisombululo samanzi se-HPC siyatshizwa size somiswe ukuze senze ifilimu ecacileyo), kunciphisa ukulahleka kwamanzi kunye nongcoliseko lweentsholongwane, kwaye kwandise ixesha lokugcinwa.

Isiphuculi sokubhaka

IHydroxypropyl Cellulose yongezwa kwintlama yesonka neyekhekhe ukuphucula ulwandiso lwentlama, okwenza imveliso egqityiweyo ibe thambile kwaye ithambe, kwaye yandise ubomi bayo (umlinganiselo yi-0.2% ukuya kwi-0.5%).

3. Kwicandelo leekhemikhali zemihla ngemihla kunye nezinto zokuthambisa

Iimveliso zokhathalelo lolusu

IHydroxypropyl Cellulose, njenge-moisturizer kunye ne-thickener, isetyenziswa kwi-lotions, ii-face creams kunye ne-essences ukwandisa i-viscosity yeemveliso (ukuphucula ulusu xa lusetyenziswa), kwaye kwangaxeshanye yenze ifilimu kumphezulu wesikhumba ukunciphisa ukufuma kwamanzi (ixesha lokufuma linokufikelela kwiiyure ezi-4 ukuya kwezi-8).

Iinto zokuzilungisa

IHydroxypropyl Cellulose isetyenziswa kwisiseko nakwimascara njengesixhobo sokwenza ifilimu kunye ne-dispersant, nto leyo ephucula ukunamathela kwe-makeup (akunakwenzeka ukuba iphume), kwaye kwangaxeshanye yenza umbala usasazeke ngokulinganayo (umbala ozinzileyo ngakumbi).

Intlama yamazinyo

IHydroxypropyl Cellulose, njenge-binder kunye ne-thickener, ilawula i-viscosity ye-toothpaste (ithintela amasuntswana aqinileyo ukuba angahlali), iphucula "imvakalelo ye-stringy" ngexesha lokuxubha, kwaye ayicaphukisi.

4. Amanye amacandelo emizi-mveliso

Iingubo kunye nee-inki

IHydroxypropyl Cellulose isetyenziswa njenge-thickener kunye ne-leveling agent kwi-water-based coatings kunye ne-printing inks ukuthintela i-pigment sedimentation kunye nokuphucula i-leveling property ye-coatings (ukuphepha iimpawu zebrashi).

Ishishini lezinto zokwakha

IHydroxypropyl Cellulose isetyenziswa kwisamente mortar kunye neputty powder njengearhente yokugcina amanzi (ukunciphisa ukufuma kwamanzi okugqithisileyo kunye nokuthintela ukuqhekeka) kunye ne-thickener (ukuphucula ukugeleza kolwakhiwo).

Izixhobo ze-elektroniki

I-HPC ecocekileyo kakhulu isetyenziswa njenge-resin yokwenza ifilimu ye-photoresist kwinkqubo yokwenza ii-chip ze-semiconductor (umxholo wokungcola kufuneka ulawulwe ngokungqongqo).

Iimbonakalo

1. Kukho iinkcukacha ezininzi ze-viscosity. Ii-HPCS ezisibhozo ezahlukeneyo zihambelana ne-viscosity ezahlukeneyo ngokwecandelo leyeza lomthengi. Isiphumo sokusebenzisa singcono.
2. Umxholo weekhompawundi ze-arsenic uphantsi. Umxholo we-arsenic kwimarike ungaphantsi kwe-200 PPM, kwaye singawulawula ube ngaphantsi kwe-2PPM. Ukuyifaka kumachiza akunabungozi kangako kwaye kusebenza ngakumbi.
3. Singayilungisa i-HPC ene-viscosity ephezulu. Inkcazo ye-viscosity ephezulu ingasetyenziswa njengezinto zokulungiselela ukukhululwa okuqhubekayo kunye nokukhululwa okulawulwayo. Ngokulungisa i-viscosity, izinga lokukhululwa kwamayeza linokulawulwa ngokuchanekileyo, ngaloo ndlela kwandisa ukusebenza kakuhle kwemveliso egqityiweyo.

Iphakheji

Izithako ze-Hydroxypropyl cellulose yi-cellulose yendalo eguquliweyo, eyenziwe nge-cellulose yendalo ngokuguqulwa kweekhemikhali kwaye ayinazo izinto ezintsonkothileyo ezinamacandelo amaninzi. I-Hydroxypropyl cellulose safe yaziwa kwihlabathi liphela. Ukuba ufuna ukuthenga i-hydroxypropyl cellulose, i-w iya kukunika ixabiso elihle. 25kg/drum.
