Kev sib raug zoo ntawm viscosity thiab qhov kub ntawm hydroxypropyl methylcellose (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 Hom Viscometer;
(2) Cov tsos ntawm cov khoom yog hmoov, thiab cov khoom lag luam tam sim no yog cov tsiaj ntawv tau nrog "S" hauv lub npe lag luam.
Yuav ua li cas siv hydroxypropyl methylcelulose
Nws yog ncaj qha ntxiv thaum lub sijhawm ntau lawm. Txoj kev no yog qhov yooj yim thiab luv tshaj plaws-kev siv sijhawm. Cov kauj ruam tshwj xeeb yog:
1. Ntxiv qee qhov nyiaj ntawm cov dej npau npau rau lub nkoj txhaws nrog cov khoom siv cellulose siab (lub hydrotyl cellulose cov khoom yog solub hauv dej txias, yog li tsuas yog 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 los ntawm;
4. Ntxiv cov dej txias txaus thiab txuas ntxiv mus kom txog thaum tag nrho cov khoom yog yaj tag (cov pob tshab ntawm txoj kev daws teeb meem yog nce);
5. Tom qab ntawd ntxiv lwm cov khoom xyaw hauv cov mis.
Npaj leej niam cawv rau kev siv: Cov khoom no yog los npaj cov khoom lag luam rau hauv ib leej niam cawv nrog kev xav tau ntau dua, 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 (1-3) nyob rau hauv txoj kev ntxiv mus. Tom qab cov khoom yog ntub dej, cia nws sawv ntsug rau ntuj txias kom yaj, thiab tom qab ntawd tag nrho cov xim 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.
Siv cov hmoov tov sib xyaw qhuav: Tom qab qhuav cov khoom thiab cov khoom hmoov (xws li cassim, thiab ua kom tiav 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 nws yaj tag.
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 maj mam siled rau hauv lub thawv sib xyaw, thiab tsis ncaj qha ntxiv cov khoom lag luam uas tau tsim rau hauv cov thawv ntim rau hauv cov khoom sib xyaw;
(3) PHU ntawm cov dej kub thiab dej muaj kev sib raug zoo tseem ceeb nrog kev sib txawv ntawm cov khoom lag luam, thiab mloog tshwj xeeb yuav tsum tau them;
(4) Tsis tas li cov tshuaj alkaline rau cov tshuaj txhuam ntxiv ua ntej cov khoom hmoov ua tau tsau nrog dej photes, thiab nce tus nqi PH tom qab noj, uas yuav pab 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 haus cawv yuav tsum tsis txhob siab dua 2.5-3%, tsis yog li tus niam cawv yog qhov nyuaj ua haujlwm;
(7) cov khoom lag luam uas tau txais kev kho tam sim ntawd yuav tsum tsis txhob siv rau hauv cov khoom noj lossis khoom lag luam.
