Indlela yokusebenzisa i-hydroxypropyl methylcellulose kunye nendlela yokulungiselela isisombululo

Uyisebenzisa njani ihydroxypropyl methylcellulose:

Yongeza ngokuthe ngqo kwimveliso, le ndlela yeyona ndlela ilula kwaye imfutshane ithatha ixesha, amanyathelo athile alandelayo:

1. Yongeza umlinganiselo othile wamanzi abilayo (imveliso ye-hydroxyethyl cellulose iyanyibilika emanzini abandayo, ngoko unokongeza amanzi abandayo) kwisingxobo esiphezulu soxinzelelo lwe-shear;

2. Vula ukuvuselela kunye nokusebenza kwesantya esiphantsi, kwaye ucofe ngokucotha imveliso kwisitya esishukumisayo;

3. Qhubeka uvuselela de onke amaqhekeza afumiswe;

4. Yongeza amanzi abandayo ngokwaneleyo kwaye uqhubeke uvuselela de yonke imveliso ichithwe ngokupheleleyo (ukukhanya kwesisombululo kuphuculwe kakhulu)

5. Emva koko yongeza ezinye izithako kwifomula

Izinto ekufuneka uzikhumbule xa ulungiselela izisombululo

(1) Iimveliso ngaphandle konyango lomphezulu (ngaphandlei-hydroxyethyl cellulose) mayinganyibiliki ngokuthe ngqo emanzini abandayo

(2) Kufuneka ihluzwe ngokucothayo kwisitya sokuxuba, ungafaki imveliso eninzi ngqo kwisitya sokuxuba.

(3) Ubushushu kunye nexabiso le-pH yamanzi linobudlelwane obucacileyo kunye nokuchithwa kwemveliso, ngoko ke kufuneka kuhlawulwe ingqalelo ekhethekileyo.

(4) Ngaphambi kokuba umgubo wemveliso ube manzi, musa ukongeza ezinye izinto zealkaline kumxube, kuphela emva kokuba umgubo wemveliso umanzi, ixabiso le-ph linganyuswa, eliya kunceda ukuchithwa.

(5) Yongeza kwangaphambili i-agent anti-fungal kangangoko kunokwenzeka

(6) Xa usebenzisa iimveliso ze-viscosity ephezulu, ubunzima bobunzima botywala lomama akufanele budlule i-2.5% -3%, kungenjalo utywala oomama kunzima ukusebenza.

(7) Iimveliso eziye zafumana unyango olukhawulezileyo aziyi kusetyenziselwa ukutya okanye iyeza
