Nyob rau hauv kev tsim kho ntawm phab ntsa putty, HPMC (hydroxypropyl methylcellulose) yog ib qho kev siv tshuaj ntxiv uas tuaj yeem txhim kho kev ua tau zoo ntawm putty.
1. Xaiv hom HPMC tsim nyog
HPMC muaj nyob rau hauv ntau yam qauv nrog txawv viscosities thiab dej solubility. Thaum xaiv HPMC, tus qauv tsim nyog yuav tsum tau txiav txim siab raws li cov qauv putty thiab kev siv ib puag ncig. Feem ntau, tsawg viscosity HPMC yog haum rau putties uas yuav tsum tau ceev daim ntawv thov, thaum siab viscosity HPMC yog haum rau putties uas yuav tsum tau ntev qhib lub sij hawm thiab muaj zog adhesion.
2. Precisely tswj ntau npaum
Tus nqi ntawm HPMC ncaj qha cuam tshuam rau kev ua haujlwm ntawm putty. Feem ntau, qhov sib ntxiv ntawm HPMC yog nyob nruab nrab ntawm 0.5% thiab 2%, uas tau hloov kho raws li cov yam ntxwv ntawm cov khoom thiab kev tsim kho. Kev siv ntau dhau ntawm HPMC tuaj yeem ua rau lub sijhawm ziab ntawm lub putty thiab cuam tshuam rau kev tsim kho; thaum siv tsis txaus yuav cuam tshuam rau adhesion thiab kev ua haujlwm ntawm lub putty. Yog li ntawd, cov koob tshuaj yuav tsum nruj me ntsis tswj nyob rau hauv cov mis.
3. Kev npaj tsim nyog
Thaum lub sij hawm npaj cov txheej txheem ntawm putty, nws raug nquahu kom yaj HPMC hauv dej huv los tsim cov kua colloidal sib xws, thiab tom qab ntawd sib tov nrog lwm cov khoom siv raw. Txoj kev no tuaj yeem tiv thaiv HPMC agglomeration thiab xyuas kom meej tias nws txawm dispersion nyob rau hauv lub putty, yog li txhim kho cov kev ua tau zoo ntawm lub putty.
4. Txhim kho qhov chaw tsim kho kom zoo
HPMC nthuav tawm cov khoom sib txawv hauv qhov sib txawv ntawm qhov kub thiab txias. Feem ntau, qhov kub thiab av noo ntau dua yuav ua rau kom muaj kev sib cais thiab ua haujlwm ntawm HPMC. Yog li ntawd, thaum lub sij hawm tsim kho, qhov tsim nyog qhov kub thiab av noo ntawm ib puag ncig yuav tsum tau tswj kom ntau li ntau tau kom optimize cov nyhuv ntawm putty.
5. Txhim kho kev ua haujlwm ntawm putty
HPMC tuaj yeem txhim kho qhov slipperiness thiab operability ntawm putty, ua kev tsim smoother. Txhawm rau muab kev ua si tag nrho rau qhov kom zoo dua no, thaum tsim cov putty, qhov feem pua ntawm HPMC tuaj yeem tsim nyog nce ntxiv kom ntseeg tau tias kev ua haujlwm zoo ntawm putty thaum ua haujlwm tsim kho thiab txo qis kev siv zog ntawm cov neeg ua haujlwm tsim kho.
6. Txhim kho qhov adhesion ntawm putty
Qhov sib ntxiv ntawm HPMC tuaj yeem txhim kho qhov adhesion ntawm putty, tso cai rau nws ua kom zoo dua rau lub hauv paus nto thiab txo qhov kev pheej hmoo ntawm tev thiab poob. Ua ntej kev tsim kho, lub hauv paus txheej yuav tsum tau kho tag nrho kom ntseeg tau tias qhov chaw huv si thiab tsis muaj cov roj stains kom ua kom cov nyhuv adhesion ntawm HPMC.
7. Txhim kho qhov tawg tsis kam
HPMC tuaj yeem txhim kho qhov tawg tsis kam ntawm putty, tshwj xeeb tshaj yog nyob rau hauv qhov chaw qhuav thiab kub hloov pauv. Los ntawm kev kho tus nqi ntawm HPMC, qhov yooj thiab tawg tsis kam ntawm putty tuaj yeem txhim kho rau qee yam, yog li txuas ntxiv lub neej kev pab cuam ntawm putty.
8. Ua cov kev sim kom tsim nyog
Ua ntej kev tsim kho loj, nws raug nquahu kom ua qhov kev sim me me los txheeb xyuas qhov cuam tshuam ntawm HPMC ntau npaum li cas ntawm kev ua haujlwm ntawm putty. Los ntawm kev sim, cov qauv zoo tuaj yeem pom los xyuas kom muaj kev tsim kho zoo.
9. Ua tib zoo mloog cov lus tawm tswv yim ua lag luam
Kev lag luam thov rau phab ntsa putty yog hloov pauv tas li, yog li nws tseem ceeb heev uas yuav tsum tau ua tib zoo saib xyuas cov neeg siv khoom tawm tswv yim thiab kev paub dhau los. Kho kev siv HPMC raws li kev lag luam tawm tswv yim tuaj yeem ua tau raws li cov neeg siv xav tau.
Los ntawm kev xaiv tsim nyog, kev tswj xyuas meej, kev ua kom zoo dua qub, thiab ua tib zoo saib rau qhov chaw tsim kho, lub luag haujlwm ntawm HPMC hauv phab ntsa putty tuaj yeem siv tau tag nrho thiab kev ua haujlwm thiab kev tsim kho ntawm lub putty tuaj yeem txhim kho. Raws li kev siv thev naus laus zis thiab kev lag luam xav tau hloov pauv, nws tseem yuav tsum tau kawm txuas ntxiv thiab txhim kho cov txheej txheem tsim kho. Kuv vam tias cov lus qhia no yuav pab tau rau koj cov phab ntsa putty.
