Kev sib raug zoo ntawm viscosity thiab qhov kub ntawm hydroxyprropy cellulose (HPMC)

(1) Kev txiav txim siab ntawm viscosity: cov khoom qhuav yog npaj rau cov tshuaj aqueous nrog lub cev hnyav ntawm 2 ° C, thiab yog ntsuas los ntawm NDJ-1 cov visicals;

(2) Cov tsos ntawm cov khoom yog powdery, thiab cov khoom tseem tam yog prodixed nrog "s".

Yuav ua li cas siv hydroxypropyl methylcelulose

Ntxiv qha ncaj qha thaum lub sij hawm tsim khoom, hom no yog qhov yooj yim thiab lub sijhawm luv tshaj plaws siv cov qauv, cov kauj ruam tshwj xeeb yog:

1. Ntxiv qee qhov nyiaj ntawm cov dej npau npau nrog lub nkoj uas muaj kev ntxhov siab ntau dua (Hydroxyethyl cellle cov khoom yog soluble hauv dej txias, yog li ntxiv dej txias);

2. Tig rau lub stirring ntawm qhov nrawm nrawm, thiab maj mam sab cib cov khoom lag luam rau hauv lub thawv stirring;

3. Txuas ntxiv nplawm kom txog thaum txhua qhov sib luag tau tsau;

4. Ntxiv cov dej txias txaus thiab txuas ntxiv mus do kom txog thaum txhua cov khoom siv tag (cov lus qhia ntawm cov kev daws teeb meem tau nce siab);

5. Tom qab ntawd ntxiv lwm cov khoom xyaw hauv cov mis.

Npaj cov cawv niam rau kev siv: Cov khoom no yog ua kom cov khoom siv rau hauv ib leej niam nrog ua ntej, thiab tom qab ntawd ntxiv rau cov khoom. Qhov kom zoo dua yog tias nws tau muaj kev yoog tau zoo thiab tuaj yeem txuas ntxiv ntxiv rau cov khoom tiav. Cov kauj ruam yog tib yam li cov kauj ruam (1-3) nyob rau hauv txoj kev ntxiv. Tom qab cov khoom lag luam yog tag nrho wetted, cia nws sawv ntsug rau ntuj txias kom yaj, thiab tom qab ntawd tag nrho do ua ntej siv. Nws yuav tsum raug sau tseg tias tus neeg sawv cev tiv thaiv kab mob yuav tsum tau ntxiv rau niam cawv niam hmo kom sai li sai tau.

Kev sib xyaw qhuav: tom qab qhuav cov khoom thiab cov khoom hmoov (xws li MAEMSUM, CARRAYS, ceramic av, ceramic av thiab do kom txog thaum cov khoom yaj tag.

Kev rhuav tshem cov dej txias cov khoom txias: dej txias cov khoom lag luam tuaj yeem txuas ncaj qha ntxiv rau dej txias rau kev xaus. Tom qab ntxiv dej txias, cov khoom yuav ua dab nrawm. Tom qab tau ntub rau qee lub sijhawm, pib nplawm kom txog thaum yaj kiag.

Kev ceev faj thaum npaj cov kev daws teeb meem

(1) Cov khoom lag luam tsis muaj kev kho deg (tshwj tsis yog hydroxyethyl cellulose) yuav tsum tsis ncaj qha nrog cov dej txias;

(2) Nws yuav tsum yog maj mam siled rau hauv lub thawv sib xyaw, tsis txhob ncaj qha ntxiv qhov nyiaj lossis cov khoom uas tau tsim rau hauv cov thawv ntim;

(3) Cov dej kub thiab tus nqi ntawm cov dej muaj qhov pom tseeb nrog kev sib cais ntawm cov khoom, yog li kev saib xyuas tshwj xeeb;

(4) Tsis tas li cov tshuaj alkaline rau cov khoom sib xyaw ua ke ua ntej cov khoom lag luam ua kua txiv ntoo, thiab nce tus nqi PH tom qab nws ua rau yaj;

(5) kom deb li deb tau, ntxiv cov antifungal neeg sawv cev ua ntej;

(6) Thaum siv cov khoom lag luam uas siab tshaj plaws, lub qhov hnyav ntawm cov niam cawv yuav tsum tsis txhob siab dua 2.5-3%, txwv tsis pub tus niam npau taws;

(7) cov khoom lag luam uas tau ua tiav-yaj yuav tsum tsis txhob siv hauv cov khoom noj lossis khoom siv tshuaj.
