Raws li ib qho kev kho kom zoo nkauj lub tsev, cov caulking tus neeg sawv cev yog dav siv los sau cov vuas luaj, thiab lwm yam. Txhawm rau kom ntseeg tau tias lub tiaj tiaj, thiab kev ua kom zoo nkauj thiab sib khi ntawm nto. Nyob rau hauv xyoo tas los, nrog kev txhim kho ntawm lub tsev ua tau zoo, kev ua yeeb yam ntawm Caulking tus neeg sawv cev tau them ntau dua thiab ntau mloog. Ntawm lawv, hnav tsis kam, raws li kev ua tau zoo ntsuas, muaj qhov cuam tshuam ncaj qha rau lub neej pabcuam thiab cov txiaj ntsig zoo nkauj ntawm caulking tus neeg sawv cev.HydroxyPropyyl Methylcellulose (HPMC), raws li ib feem ntau siv cov hmoov polymer uas feem ntau siv los ua cov tuab dua, dej tuav tus neeg sawv cev, rheology kho cov neeg sawv cev, thiab lwm yam hauv Caulking tus neeg sawv cev. Qhov kev sib txuas ntawm HPMC tsis tuaj yeem txhim kho kev tsim kho kev ua tau zoo ntawm Caulking tus neeg sawv cev, tab sis kuj txhim kho nws cov coj tsis kam rau qee yam.
1. Cov yam ntxwv ntawm HPMC
HPMC yog cov polymer compound muaj los ntawm ntuj cog fibers (xws li ntoo pulp lossis paj rwb), uas muaj cov dej so zoo nkauj thiab cov khoom noj zoo. Raws li cov tuab dua, HPMC tuaj yeem hloov kho cov rheology ntawm caulking tus neeg sawv cev thiab txhim kho nws txoj haujlwm ua haujlwm thaum kev tsim kho. Ib qho ntxiv, ntxhov siab ® Yog li ntawd, HPMC tau siv dav hauv cov nplaum, txheej, caulking cov neeg sawv cev thiab lwm yam khoom hauv kev tsim kho.
2. Hnav tsis kam ntawm cov caulking cov neeg sawv cev
Hnav tsis kam lees txog qhov muaj peev xwm ntawm cov khoom siv los tiv thaiv nyob rau sab nraud rog. Nyob rau hauv caulking cov neeg sawv cev, tsuas yog coj los ntawm qhov tseeb uas nws nto tsis yooj yim puas, peeled tawm los yog muaj cov cim hnav pom tseeb vim ntev txoj kev sib txhuam. Cov ris tsho tiv thaiv ntawm cov caulking cov neeg sawv cev yog qhov tseem ceeb rau kev pabcuam lub neej ntawm cov neeg muaj kev sib txhuam, feem ntau yog cov khw muag khoom, chav ua noj, chav ua mov rau lwm thaj chaw. Caulking cov coj tsis zoo yuav ua rau muaj kev poob qis ntawm cov khoob khoob, cuam tshuam cov txiaj ntsig zoo nkauj thiab tuaj yeem tsim teeb meem xws li dej saib.
3. Cov nyhuv ntawm HPMC ntawm cov hnav tsis kam ntawm cov caulking cov neeg sawv cev
Txhim kho cov khoom sib dhos ntawm cov neeg sawv cev
Qhov sib ntxiv ntawm kev txhawjincel ® tuaj yeem txhim kho cov khoom siv hluav taws xob rheological ntawm caulking cov neeg sawv cev. Nws cov nyhuv thickening ua rau cov caulking tus neeg sawv cev muaj cov khoom tsim kho tau zoo dua, zam cov khoom siv sag tau los ntawm kev siv ntau yam, thiab txhim kho kev sib raug zoo ntawm cov caulking tus neeg sawv cev. Ib qho ntxiv, thickening kom zoo tuaj yeem kuj tseem tuaj yeem ua kom paub tseeb qhov tseeb ntawm Caulking tus neeg sawv cev, kom nws tsim cov qauv kev ua kom tawv nqaij thiab ua kom muaj qhov tshwm sim ntawm cov kab mob ntawm cov kab mob lossis tawg. Cov xwm txheej no ncaj qha txhim kho cov hnav tsis kam ntawm Caulking tus neeg sawv cev nto, vim tias cov khaub ncaws hnav thiab nruj thiab nruj tus qauv tuaj yeem ua tau zoo dua ntawm cov rog sab nraud.
Txhim kho cov dej tsis kam thiab dej ua kom rov qab los ntawm cov caulking tus neeg sawv cev
Cov dej solubility thiab dej khaws cia HPMC kuj ua tau lub luag haujlwm tseem ceeb hauv kev coj tsis kam ntawm Caulking tus neeg sawv cev. HPMC tuaj yeem ncua kev hloov kho ntawm cov khoom siv tus neeg sawv cev hauv cov dej, xyuas kom cov txheej txheem kom muaj dej nyuaj, yog li kev txhim kho nws lub zog tawv thiab lub zog. Lub zog siab pab lub caulking tus neeg sawv cev zoo dua kev hnav thiab txo cov teeb meem xws li kev tawg, sanding thiab shedding dej evaporation.
Ua ib tug ruaj khov network qauv
Lub luag haujlwm ntawm HPMC hauv Caulking tus neeg sawv cev tsis txwv rau thickening. Nws kuj tseem tuaj yeem ua tus qauv siv nyiaj ruaj khov nrog lwm cov khoom xyaw xws li Maint thiab Gypsum. Cov qauv no tuaj yeem nce qhov ceev ntawm tus muab tub lim, ua nws lub npoo nyuaj thiab ntau cov hnav-resistant. Tus qauv network ntawm cov muab tub rog tawv kuj muaj peev xwm tiv thaiv qhov kev cuam tshuam ntawm sab nraud xws li kev sib txhuam thiab kev ua kom txo qis. Qhov kev ruaj ntseg ntawm tus qauv network yog ze ze rau cov kev hnyav molecular thiab qib hloov chaw ntawm HPMC. HPMC nrog lub cev hnyav dua thiab cov qib siab dua thiab cov qib hloov kho uas muaj peev xwm hnav muaj zog hnav tsis kam.
Txhim kho qhov cuam tshuam tsis ntawm cov muab tub lim
Tus yam ntxwv loj ntawm Kev txhawj xeeb ® Qhov kev cuam tshuam no yog ze ze rau kev hnav tsis kam, vim tias thaum lub sij hawm sib txhuam, yuav raug rau qhov cuam tshuam me me, ua kom muaj kev pheej hmoo me me ntawm cov khoom hnav. Qhov sib ntxiv ntawm HPMC txhim kho cov tawv ntawm tus muab tub lim, ua rau nws tsis tshua ua txhaum rau hauv kev sib txhuam.
4. Kev txhim kho lub tswv yim ntawm HPMC ntawm cov coj tsis kam ntawm cov muab tub lim
Txhawm rau txhawm rau txhim kho cov hnav tsis kam ntawm HPMC hauv cov muab tub lim, cov kws tshawb nrhiav thiab cov kws ua engineers tuaj yeem ua kom tau zoo los ntawm cov hauv qab no:
Xaiv cov hom HPMC tsim nyog: cov molecular hnyav thiab qib ntawm kev hloov pauv ntawm HPMC muaj qhov cuam tshuam ncaj qha rau kev ua haujlwm ntawm tus muab tub lim. HPMC nrog lub siab ntau dua cov nyhuv ntau dua thiab cov khoom siv hluav taws xob zoo dua, tab sis ua kom hnyav dua yuav ua rau txo qis cov khoom. Yog li ntawd, thaum xaiv cov ntaub ntawv, nws yog qhov tsim nyog los xaiv qhov tsim nyog HPMC ntau ntau yam raws li cov cai ntawm daim ntawv qhia kev cai tshwj xeeb.
Kho tus nqi HPMC ntxiv: Tus nqi ntawm HPMC tsim nyog txhim kho cov caulking tus neeg sawv cev, tab sis muaj kev cuam tshuam zoo, yog li cuam tshuam nws cov kev cuam tshuam tsis kam. Yog li ntawd, nws yog qhov tsim nyog los txiav txim siab qhov kev pom zoo ntawm HPMC ntxiv los ntawm kev sim.
Sib xyaw nrog lwm cov khoom xyaw: ntawm lub hauv paus ntawmHPMC, ntxiv ib co fitters xws li kev txhawb nqa cov fibers thiab nanomaterials tuaj yeem txhim kho cov coj tsis kam ntawm cov caulking tus neeg sawv cev. Piv txwv li, cov ntaub ntawv xws li Nano-silicon thiab nano-alumina tuaj yeem tsim cov qauv me me uas yog cov khoom siv hluav taws xob, txhim kho nws cov tawv tawv thiab hnav tsis kam.
Raws li qhov tseem ceeb ntxiv hauv Caulking tus neeg sawv cev, HPMC tuaj yeem txhim kho nws cov kev coj ua kom tsis kam los ntawm kev txhim kho cov khoom siv tiv thaiv, kev ua haujlwm hnyav thiab cuam tshuam ntawm cov caulking tus neeg sawv cev. Los ntawm kev xaiv los ntawm hom thiab tus nqi ntawm kev txhawj xeeb ® Nrog rau kev txhim kho txuas ntxiv ntawm kev xav tau ntawm cov ntaub ntawv hauv tsev, daim ntawv thov kev cia siab ntawm HPMC hauv kev tshawb fawb dav dav thiab tsim nyog ntawm kev tshawb fawb ntxiv thiab kev loj hlob.
