Iinkalo zesicelo se-hydroxy propyl methylcellulose

IHydroxy propyl methylcellulose (HPMC) yimveliso eyenziweyo yeselulosi esetyenziswa kakhulu kwimizi-mveliso eyahlukeneyo ngenxa yendlela egqwesileyo yokwenza ifilimu, ukugcinwa kwamanzi, kunye neempawu ezityebileyo. I-HPMC ngumgubo omhlophe ukuya kumhlophe, ongenavumba, kwaye ongenancasa onyibilikayo emanzini abandayo, okwenza kube lula ukusebenza nawo kwizicelo ezininzi ezahlukeneyo. Nazi ezinye zeendawo eziphambili zesicelo se-HPMC:

1. Ishishini loKwakha

I-HPMC isetyenziswa kakhulu kushishino lokwakha njengento etyebisayo, iarhente yokugcina amanzi, kunye nesibophelelo. Isetyenziswa ngokuqhelekileyo kwiimveliso ezisekelwe kwisamente, ezifana nodaka, i-grouts, kunye ne-renders, ukuphucula ukusebenza, ukunamathela kunye nokuqina. I-HPMC ingasetyenziswa njenge-arhente yokwaleka kwibhodi yegypsum nanjenge-lubricant kwimveliso yeethayile ze-ceramic.

2. Ishishini lezamayeza

I-HPMC isetyenziswa kakhulu kushishino loxubo-mayeza njenge-excipient, into leyo eyinto engasebenziyo eyongezwa kwichiza ukunceda unikezelo lwalo, ukufunxa, kunye nokuzinza. Isetyenziswa ngokuqhelekileyo njenge-binder, i-disintegrant, kunye ne-ejenti yokukhululwa okuqhubekayo kwiipilisi kunye neepilisi. I-HPMC ikwasetyenziswa kwizisombululo zamehlo nakwizitshizi zempumlo njengesiphuculi se-viscosity kunye ne-lubricant.

3. Ishishini lokutya

I-HPMC isetyenziswa kushishino lokutya njenge-emulsifier, i-thickener, kunye ne-stabilizer. Ngokuqhelekileyo kusetyenziswa kwiimveliso zobisi, ezifana ne-ayisikrimu, ukuphucula ukuthungwa kunye nokuthintela ukubunjwa kwekristale ye-ice. I-HPMC ingasetyenziselwa ukuzinzisa iisosi, izinxibo zesaladi, kunye neesuphu. Ukongeza, i-HPMC isetyenziselwa ukugquma iziqhamo kunye nemifuno esitsha ukuthintela ukulahleka kokufuma kunye nokwandisa ubomi beshelufu.

4. Ishishini lokuKhathalela umntu

I-HPMC iqhele ukusetyenziswa kushishino lokhathalelo lobuqu njenge-thickener, binder, kunye nefilimu-yangaphambili kwiimveliso zokuthambisa, ezifana neloshini, iikhrimu, neeshampu. Inceda ekuphuculeni ukuthungwa kunye nokungaguquguquki kwezi mveliso kwaye ikwabonelela ngeempawu zokuthambisa kunye nemeko. I-HPMC ingasetyenziswa njenge-arhente yokunqumamisa izithako ezinganyibilikiyo kwaye njenge-stabilizer ye-emulsions.

5. Ishishini leengubo

I-HPMC isetyenziswa kwishishini lezogquma njengesibophelelo, ifilimu-yangaphambili, kunye ne-thickener. Ngokuqhelekileyo isetyenziswe kwiingubo ezisekelwe emanzini, njengepeyinti kunye neevanishi, ukuphucula ukunamathela, ukuqina, kunye neempawu zokuhamba. I-HPMC ingasetyenziswa njenge-thickener kwii-inki zoshicilelo kwaye njengengubo yokukhusela imiphezulu yesinyithi.

6. Ishishini leMilaphu

I-HPMC isetyenziswa kushishino olulukiweyo njenge-arhente yokulinganisa kunye ne-thickener yokuncamathisela kwelaphu. Inceda ekuphuculeni ukuncamathela kokushicilela kwilaphu kwaye ikwabonelela ngeempawu ezigqwesileyo zokugcina amanzi.

7. Ishishini leoli negesi

I-HPMC isetyenziswa kushishino lwe-oyile negesi njengesongezo solwelo lokomba. Isetyenziselwa ukunciphisa ilahleko yolwelo kunye nokuzinzisa iqula ngexesha lomsebenzi wokomba. I-HPMC ingasetyenziswa njenge-fracturing fluid edibanisayo ukuphucula i-viscosity kunye nokunqunyanyiswa kwe-proppant.

Ukuqukumbela, i-hydroxypropyl methylcellulose (HPMC) i-polymer eguquguqukayo kwaye isetyenziswa ngokubanzi efumana isicelo kumashishini ahlukeneyo ngenxa yefilimu egqwesileyo yokwenza ifilimu, ukugcinwa kwamanzi, kunye neempawu zokuqina. Ulwakhiwo, amayeza, ukutya, ukhathalelo lomntu, iingubo, impahla yokuluka, kunye ne-oyile kunye negesi yegesi zezinye zeendawo eziphambili apho kusetyenziswa khona i-HPMC.
