Hydroxypropylmethylcellulose (HPMC) yog ib qho khoom siv ntau yam siv hauv ntau yam khoom siv hauv tsev. Nws muaj cov khoom tshwj xeeb uas ua rau nws yog ib qho zoo tshaj plaws ntawm nws tus kheej-leveling mortars, kom ntseeg tau tias qhov sib tov yog yooj yim rau kev thov, adheres zoo rau saum npoo thiab dries smoothly.
Self-leveling composite mortar yog ua nrov nyob rau hauv kev tsim kho kev lag luam, feem ntau vim nws yooj yim ntawm kev siv thiab muaj peev xwm muab ib tug du, txawm nto. Qhov sib ntxiv ntawm HPMC rau cov mortars no txhim kho lawv cov khoom, ua rau lawv muaj txiaj ntsig zoo thiab muaj txiaj ntsig.
Ib qho txiaj ntsig tseem ceeb tshaj plaws ntawm HPMC yog nws lub peev xwm los muab cov dej tuav tau zoo. Thaum ntxiv rau tus kheej-leveling composite mortar, nws pab khaws cov dej noo hauv qhov sib tov ntev dua. Qhov no yog ib qho tseem ceeb feature raws li nws ua kom ntseeg tau tias cov mortar composite tsis qhuav sai heev, cia tus neeg cog lus txaus lub sij hawm mus kis thiab theem.
Cov dej tuav cov khoom ntawm HPMC pab tiv thaiv kev tsim cov kab nrib pleb thiab fissures hauv cov khoom sib xyaw. Qhov no yog qhov tseem ceeb los xyuas kom meej tias koj tus kheej-leveling composite screed kav ntev li ntev tau, txo qhov xav tau kev kho lossis hloov.
HPMC kuj ua raws li cov thickener los muab cov mortar sib xyaw kom haum. Qhov no ua kom ntseeg tau tias tus kheej-leveling mortar yog yooj yim dua rau kev siv thiab tuav, ua rau nws zoo tagnrho rau kev tsim kho cov haujlwm uas qhov tseeb thiab qhov tseeb yog qhov tseem ceeb.
Lub peev xwm ntawm HPMC los txhim kho cov khoom sib txuas ntawm cov mortars ua kom muaj kev sib raug zoo rau ntau qhov chaw. Qhov no yog qhov tseem ceeb los xyuas kom meej tias tus kheej-leveling mortar muaj zog thiab ruaj khov, muab lub hauv paus ruaj khov rau txhua tus qauv tsim los ntawm nws.
HPMC kuj tseem txhim kho cov sag tsis kam ntawm tus kheej-leveling mortar, ua rau nws tsis tshua muaj dej los yog poob thaum siv rau ntawm qhov chaw ntsug. Qhov no yog qhov tseem ceeb los xyuas kom meej tias cov mortar sib xyaw yog siv sib npaug thiab tsis tu ncua, muab qhov du, txawm tias nto.
HPMC kuj tsis muaj tshuaj lom thiab tsis muaj kev phom sij rau ib puag ncig, ua rau nws muaj txiaj ntsig zoo rau ib puag ncig ntxiv. Nws yog biodegradable thiab yoojyim tsis muaj residue tom qab siv.
Hydroxypropyl methylcellulose (HPMC) yog ib qho zoo heev tus kheej-leveling mortar additive. Nws cov khoom tshwj xeeb tau txhim kho cov dej tuav, adhesion thiab ua haujlwm ntawm cov khoom sib xyaw. Tsis tas li ntawd, nws yog non-toxic thiab environmentally friendly, ua nws additive ntawm kev xaiv nyob rau hauv kev tsim kho kev lag luam. Los ntawm kev siv HPMC tsis tu ncua, cov neeg cog lus tuaj yeem ua tiav cov haujlwm du, ruaj khov thiab ua tiav zoo ntawm lawv cov haujlwm tsim kho.
Hydroxypropyl methylcellulose nqi-caulk HPMC
Hydroxypropyl methylcellulose, feem ntau hu ua HPMC, yog ntau yam polymer siv nyob rau hauv ntau yam kev lag luam. Nws cov khoom tshwj xeeb ua rau nws muaj txiaj ntsig zoo hauv ntau yam kev siv, suav nrog cov khoom siv hauv tsev, tshuaj, khoom noj, tshuaj pleev ib ce, thiab lwm yam.
Kev siv ntawm hydroxypropyl methylcellulose
kev tsim kho kev lag luam
Ib qho tseem ceeb tshaj plaws ntawm kev siv HPMC yog nyob rau hauv kev tsim kho kev lag luam, qhov twg nws yog siv los ua tus neeg sawv cev caulking. HPMC yog siv nyob rau hauv grouts, pobzeb adhesives, varnishes thiab self-leveling compounds los txhim kho dej tuav, workability thiab adhesion. Ntxiv HPMC rau cov ntaub ntawv cementitious ua rau kom muaj zog ntawm daim ntawv cog lus thiab tiv thaiv qhov sib tov los ntawm kev tawg. Nws pab tswj qhov sib xws thiab thixotropy ntawm kev sib xyaw, txhim kho kev ua haujlwm, txo qis, thiab txhim kho dej tuav thaum kho.
tshuaj
HPMC yog siv dav hauv kev npaj tshuaj, tshwj xeeb tshaj yog cov ntsiav tshuaj coatings thiab sustained-tso npaj. Nws yog siv los ua ib qho binder, emulsifier, disintegrant thiab thickening tus neeg sawv cev hauv cov tshuaj sib txuas. HPMC yog siv nyob rau hauv cov tshuaj pleev ib ce, gels, thiab cream kom viscosity, txhim khu kev nkag mus rau ntawm daim tawv nqaij, thiab xyuas kom meej kev faib ntawm cov tshuaj.
Khoom noj khoom haus thiab tshuaj pleev ib ce
HPMC yog cov khoom muaj nyob rau hauv cov khoom noj thiab tshuaj pleev ib ce. Siv ua thickener, emulsifier thiab stabilizer hauv cov khoom noj. HPMC feem ntau yog siv hauv cov dej khov nab kuab, cov txiv hmab txiv ntoo ua tiav thiab cov khoom ci. Nyob rau hauv cov tshuaj pleev ib ce, nws yog siv raws li ib tug thickener, emulsifier thiab suspending tus neeg sawv cev nyob rau hauv cream, lotions thiab tshuaj zawv plaub hau.
Cov yam ntxwv cuam tshuam rau tus nqi ntawm hydroxypropyl methylcellulose
Hydroxypropyl methylcellulose hom
Muaj ntau hom HPMC ntawm kev ua lag luam, txhua tus muaj nws tus kheej cov khoom tshwj xeeb. Piv txwv li, low-viscosity HPMC yog ntau soluble hauv dej thiab dissolves sai, ua rau nws zoo tagnrho rau tam sim-tso tshuaj. Nyob rau tib lub sijhawm, high-viscosity HPMC muaj qhov sib cais qeeb thiab tsim nyog rau kev npaj tawm-tso tawm. Hom HPMC siv yuav cuam tshuam rau nws tus nqi.
Purity thiab concentration
Lub purity thiab concentration ntawm HPMC kuj cuam tshuam rau nws tus nqi. Purer HPMC yog kim dua vim qhov kev ua haujlwm ntxiv yuav tsum tau txais HPMC ntshiab. Ib yam li ntawd, qhov siab dua ntawm HPMC tseem yuav cuam tshuam rau nws tus nqi vim tias cov khoom siv raw yuav tsum tau ua ntau dua.
Qhov chaw ntawm raw khoom
Lub hauv paus ntawm cov khoom siv raw siv los tsim HPMC kuj cuam tshuam rau nws tus nqi. HPMC feem ntau yog muab los ntawm cov ntoo ntoo lossis paj rwb linters, tom kawg yog kim dua. Qhov chaw thiab qhov zoo ntawm cov khoom siv raw siv yuav cuam tshuam tus nqi ntawm cov khoom kawg.
Kev lag luam xav tau
Kev lag luam xav tau yog lwm qhov cuam tshuam rau HPMC tus nqi. Yog tias qhov kev thov rau HPMC yog siab, tus nqi yuav nce thiab rov ua dua. Qhov kev sib kis tsis tu ncua ntawm COVID-19 tau ua rau muaj kev xav tau ntau ntxiv rau HPMC hauv kev lag luam tshuaj raws li HPMC tau siv los tsim cov tshuaj xws li remdesivir.
Hauv cov ntsiab lus
Hydroxypropyl methylcellulose yog cov khoom siv ntau yam siv hauv ntau yam kev lag luam. Nws cov khoom tshwj xeeb ua rau nws muaj txiaj ntsig zoo hauv cov khoom siv hauv tsev, tshuaj, khoom noj thiab tshuaj pleev ib ce. Tus nqi ntawm HPMC cuam tshuam los ntawm yam xws li hom, purity thiab concentration ntawm HPMC, qhov chaw ntawm raw cov ntaub ntawv, kev lag luam xav tau thiab lwm yam. Txawm hais tias muaj ntau yam uas cuam tshuam rau nws tus nqi, HPMC tseem yog ib qho tseem ceeb polymer nrog ntau yam kev siv thiab cov txiaj ntsig.
