I-Hydroxypropyl methylcellulose, isithombe aso ngeke sizisole!

1. I-HPMC ihlukaniswe ngohlobo olusheshayo kanye nohlobo olusheshayo lokuhlakazeka

Ukuhlakazwa okusheshayo kwe-HPMC ngesijobelelo sezincwadi, inqubo yokukhiqiza, ukwengeza ukwelashwa kwe-GLLOXAL.

Uhlobo lwe-HPMC master akwengezi noma yiziphi izinhlamvu, ezifana ne- "100000" is "I-100000 Viscocity Fast Dispering HPMC".

2. Nge noma ngaphandle kwezimpawu, ezihlukile

Ukusabalalisa okusheshayo kwe-HPMC, emanzini abandayo asanda kuhlakazeka, anyamalale emanzini, ngoba i-HPMC ayikaze ihlakazeke emanzini, kungabikho mbumbulu wangempela, i-viscosity yangempela kamuva, yakha i-colloid esobala iba nkulu.

I-HPMC esheshayo, ingahlakazeka ngokushesha emanzini ashisayo cishe kuma-70 ℃, ukuze ilahlwe emazingeni okushisa athile, ukubonakala kancane kancane, kuze kube ukwakheka kwe-colloid esobala ye-viscous.

3. Nge noma ngaphandle s, ukusetshenziswa okuhlukile

I-HPMC esheshayo ingasetshenziswa kuphela ku-putty powder kanye nodaka, ku-glue key uketshezi kanye nopende kanye nokugeza izinto, kuzoba nenkinga yeqembu, ngeke isetshenziswe.

I-HPMC e-HPMC esheshayo, uhla lwesicelo lubanzi kakhulu, ku-putty powder, udaka, glue uketshezi, upende, ukupenda, akulutho.

Indlela yokuchithwa

1. Thatha inani elidingekayo lamanzi ashisayo bese ulishisa ku-80 ℃ noma ngaphezulu esitsheni. Faka lo mkhiqizo kancane kancane ngaphansi kokushukumisa kancane.

2, noma ukushisa 1/3 noma 2/3 kwamanzi ashisayo kuya kwangama-85 ℃, engeza iselula, bese ufaka inani elisele lamanzi abandayo, hlala uvuselelwa, ukupholisa inhlanganisela.

3, inani le-cellulose mesh lihamba kahle, ku-powder yokuxuba yizinhlayiyana ezihlukile, ngemuva kokuchithwa kwamanzi ngokushesha, ukwakheka kwento edingekayo.

4. Ngeza i-cellulose kancane futhi ngokulinganayo emazingeni okushisa asekamelweni, uvuse ngokuqhubekayo kwinqubo kuze kukheke kahle isixazululo esibonakalayo.

Iziphi izici ezithinta ukugcinwa kwamanzi kwe-hydroxypropylylylylylylylylylylylylylylylylylylylylylylylylylylylylylylylylylylylylylylyllop methyl cellulose?

Imikhiqizo ye-Hydroxypropylylylyly HPMC imikhiqizo ngokwayo yokugcinwa kwamanzi ivame ukuthi ithintwe yilezi zinto ezilandelayo:

1. I-HPMC homogeneity ye-cellulose ether

I-HPMC yokuphendula okufanayo, i-metholy, i-hydroxypropoxy ukusatshalaliswa okufanayo, isilinganiso esiphakeme sokugcina amanzi.

2. I-cellulose ether hpmc hot lokushisa le-gel lokushisa

Ijeli eshisayo inokushisa okuphezulu kanye nezinga eliphakeme lokugcina amanzi. Ngokuphambene nalokho, inani lokugcinwa kwamanzi liphansi.

I-3. I-HPMC ebonakalayo ye-cellulose ether

Lapho i-viscosity ye-HPMC inyuka, izinga lokugcina amanzi liyanda. Lapho i-viscosity ifinyelela ezingeni elithile, ukwanda kwezinga lokugcina amanzi kuvame ukuba isicaba.

Inani le-cellulose ether hpmc elingeziwe

Lapho inani elikhulu kakhulu le-cellulose ether hpmc elingeziwe, liphezulu inani lokugcina amanzi, lingcono umphumela wokugcina amanzi.

Ebangeni le-0.25-0.6%, izinga lokugcina amanzi lenyuka ngokushesha ngokunyuka kwenani lokungezwa. Umkhuba owandayo wamanani okugcinwa kwamanzi wehliswa phansi lapho inani lokungeza landa kakhulu.
