Raws li cov khoom siv kho kom zoo nkauj hauv tsev, tus neeg sawv cev caulk yog dav siv los sau qhov khoob hauv cov vuas hauv pem teb, cov vuas phab ntsa, thiab lwm yam. Nyob rau hauv xyoo tas los no, nrog rau kev txhim kho cov kev cai ntawm lub tsev zoo, qhov kev ua tau zoo ntawm tus neeg sawv cev caulking tau them nyiaj ntau thiab ntau dua. Ntawm lawv, hnav tsis kam, ua ib qho tseem ceeb ntawm kev ua tau zoo, muaj kev cuam tshuam ncaj qha rau lub neej kev pab cuam thiab cov nyhuv zoo nkauj ntawm tus neeg sawv cev caulking.Hydroxypropyl methylcellulose (HPMC), raws li feem ntau siv natural polymer, feem ntau yog siv los ua cov thickener, dej tuav tus neeg saib xyuas, rheology modifier, thiab lwm yam. Qhov sib ntxiv ntawm HPMC tuaj yeem tsis tsuas yog txhim kho kev tsim kho ntawm tus neeg sawv cev caulking, tab sis kuj txhim kho nws cov hnav tsis kam rau qee yam.
1. Cov yam ntxwv tseem ceeb ntawm HPMC
HPMC yog cov khoom siv polymer uas tau txais los ntawm kev hloov kho tshuaj ntawm cov nroj tsuag fibers (xws li ntoo pulp lossis paj rwb), uas muaj dej solubility zoo thiab biodegradability zoo. Raws li cov thickener, HPMC tuaj yeem kho cov rheology ntawm tus neeg sawv cev caulking thiab txhim kho nws cov haujlwm ua haujlwm thaum tsim kho. Tsis tas li ntawd, AnxinCel®HPMC kuj tseem tuaj yeem txhim kho cov dej khaws cia ntawm cov tshuaj tua kab mob, kom tsis txhob muaj cov kab nrib pleb thiab ntog los ntawm cov dej tsis txaus ntawm cov tshuaj tua kab mob. Yog li ntawd, HPMC yog dav siv nyob rau hauv cov nplaum, coatings, caulking agents thiab lwm yam khoom nyob rau hauv kev tsim kho kev lag luam.
2. Hnav tsis kam ntawm cov tshuaj tua kab mob
Hnav tsis kam yog hais txog lub peev xwm ntawm cov khoom siv los tiv thaiv kev hnav hauv qab sab nraud. Hauv cov neeg ua haujlwm caulking, hnav tsis kam yog qhov tseem ceeb hauv qhov tseeb tias nws qhov chaw tsis yooj yim puas, tev tawm lossis muaj qhov pom tseeb hnav vim kev sib txhuam mus ntev. Kev hnav tsis kam ntawm cov tshuaj tua kab mob yog qhov tseem ceeb rau kev pabcuam lub neej ntawm qhov khoob hauv cov plag tsev thiab phab ntsa, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig uas feem ntau raug kev sib txhuam los yog muaj neeg coob coob, xws li cov khw muag khoom, cov chaw pej xeem, chav ua noj, chav dej thiab lwm qhov chaw. Caulking cov neeg ua haujlwm nrog kev hnav tsis zoo yuav ua rau muaj kev poob ntau ntawm cov khoom hauv qhov khoob, cuam tshuam rau cov hniav zoo nkauj thiab yuav ua rau muaj teeb meem xws li dej seepage.
3. Qhov cuam tshuam ntawm HPMC rau kev hnav tsis kam ntawm cov tshuaj tua kab mob
Txhim kho cov khoom rheological ntawm cov tshuaj tua kab mob
Qhov sib ntxiv ntawm AnxinCel®HPMC tuaj yeem txhim kho cov khoom rheological ntawm cov tshuaj tua kab mob. Nws cov nyhuv thickening ua rau tus neeg sawv cev caulking muaj cov khoom siv zoo dua qub, zam qhov tshwm sim sag tshwm sim los ntawm kev siv ntau dhau ntawm cov khoom thaum siv, thiab txhim kho lub zog sib txuas ntawm tus neeg sawv cev caulking. Tsis tas li ntawd, kev thickening kom zoo kuj tuaj yeem ua kom qhov sib piv qhov tseeb ntawm tus neeg sawv cev caulking, kom nws tsim cov qauv zoo sib xws thaum lub sij hawm hardening txheej txheem thiab txo qhov tshwm sim ntawm qhov pores lossis tawg. Cov yam tseem ceeb no ua rau kev txhim kho qhov hnav tsis kam ntawm tus neeg sawv cev ntawm lub cev, vim tias cov qauv nruj thiab nruj tuaj yeem tiv taus qhov kev ua ntawm sab nraud.
Txhim kho cov dej tsis kam thiab dej tuav ntawm tus neeg sawv cev caulking
Cov dej solubility thiab dej tuav ntawm HPMC kuj ua lub luag haujlwm tseem ceeb hauv kev hnav tsis kam ntawm tus neeg sawv cev caulking. HPMC tuaj yeem ncua qhov kev hloov pauv ntawm tus neeg sawv cev ntawm cov dej, xyuas kom meej tias cov khoom muaj cov dej txaus thaum lub sij hawm hardening txheej txheem, yog li txhim kho nws hardening ceev thiab lub zog. Lub zog siab dua tuaj yeem pab tus neeg sawv cev ntawm lub qhov dej kom zoo dua tuaj yeem tiv taus hnav thiab txo cov teeb meem xws li tawg, xuab zeb thiab shedding los ntawm dej evaporation ntau dhau.
Tsim ib lub network ruaj khov
Lub luag hauj lwm ntawm HPMC nyob rau hauv lub caulking tus neeg sawv cev yog tsis txwv rau thickening. Nws tseem tuaj yeem tsim cov qauv sib txuas ruaj khov nrog lwm cov khoom xyaw xws li cov cement 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. Lub network qauv ntawm hardened muab tub lim tuaj yeem tiv taus qhov cuam tshuam ntawm sab nraud quab yuam xws li kev sib txhuam thiab kev co, txo qhov hnav. Kev ruaj ntseg ntawm cov qauv network yog ze ze rau qhov hnyav molecular thiab qib ntawm kev hloov ntawm HPMC. HPMC nrog qhov hnyav dua molecular thiab qhov nruab nrab ntawm kev hloov pauv tuaj yeem muab kev hnav zoo dua.
Txhim kho qhov cuam tshuam tsis kam ntawm cov muab tub lim
Cov yam ntxwv ntawm elastic AnxinCel®HPMC ua kom cov khoom ntim kom zoo dua cov kev ntxhov siab tawg thaum nws cuam tshuam los ntawm sab nraud quab yuam, zam kev tawg lossis tawg tawg los ntawm kev ntxhov siab hauv zos ntau dhau. Qhov kev cuam tshuam no cuam tshuam zoo rau kev hnav tsis kam, vim hais tias thaum lub sij hawm kev sib txhuam, qhov chaw ntawm qhov muab tub lim yuav raug rau lub zog me me, ua rau muaj kev pheej hmoo ntawm cov khoom hnav. Qhov sib ntxiv ntawm HPMC txhim kho qhov tawv ntawm qhov muab tub lim, ua rau nws tsis tshua muaj kev sib txhuam hauv kev sib txhuam.
4. Optimization lub tswv yim ntawm HPMC ntawm kev hnav tsis kam ntawm cov muab tub lim
Txhawm rau txhawm rau txhim kho qhov hnav tsis kam ntawm HPMC hauv qhov muab tub lim, cov kws tshawb fawb thiab cov kws ua haujlwm tuaj yeem ua kom zoo dua los ntawm cov hauv qab no:
Xaiv HPMC ntau yam uas tsim nyog: Qhov hnyav molecular thiab qib hloov ntawm HPMC muaj kev cuam tshuam ncaj qha rau kev ua haujlwm ntawm cov muab tub lim. HPMC nrog qhov hnyav dua molecular feem ntau muaj cov nyhuv thickening zoo dua thiab cov khoom siv rheological, tab sis siab dhau qhov hnyav molecular yuav ua rau txo qis kev tsim kho. Yog li ntawd, thaum xaiv cov ntaub ntawv, nws yog ib qho tsim nyog yuav tau xaiv HPMC ntau yam raws li qhov yuav tsum tau muaj ntawm qhov tshwj xeeb daim ntawv thov scenario.
Kho tus nqi ntawm HPMC ntxiv: Tus nqi tsim nyog ntawm HPMC tuaj yeem txhim kho qhov hnav tsis kam ntawm tus neeg sawv cev caulking, tab sis kev sib ntxiv ntau dhau yuav ua rau lub ntsej muag ntawm tus neeg sawv cev tawv nqaij tawv dhau thiab tsis muaj elasticity txaus, yog li cuam tshuam rau nws qhov cuam tshuam. Yog li, nws yog ib qho tsim nyog los txiav txim siab qhov txiaj ntsig zoo ntawm HPMC ntxiv los ntawm kev sim.
Compatibility nrog rau lwm cov khoom xyaw: nyob rau hauv lub hauv paus ntawmHPMC, ntxiv ib co fillers xws li reinforcing fibers thiab nanomaterials tuaj yeem txhim kho qhov hnav tsis kam ntawm tus neeg sawv cev caulking. Piv txwv li, cov ntaub ntawv xws li nano-silicon thiab nano-alumina tuaj yeem tsim cov qauv microscopic reinforcing hauv tus neeg sawv cev caulking, txhim kho nws qhov tawv tawv thiab hnav tsis kam.
Raws li ib qho tseem ceeb ntxiv nyob rau hauv tus neeg sawv cev caulking, HPMC tuaj yeem txhim kho nws cov hnav tsis kam los ntawm kev txhim kho cov khoom rheological, tuav dej, hardness thiab cuam tshuam ntawm tus neeg sawv cev caulking. Los ntawm rationally xaiv hom thiab tus nqi ntawm AnxinCel®HPMC, ua ke nrog rau lwm yam optimization ntsuas, lub neej kev pab cuam ntawm lub caulking tus neeg saib xyuas yuav ua tau zoo txuas ntxiv mus xyuas kom meej nws cov kev ua tau zoo nyob rau hauv ntau yam complex ib puag ncig. Nrog rau kev txhim kho tas mus li ntawm kev ua tau zoo ntawm cov khoom siv hauv tsev, daim ntawv thov kev cia siab ntawm HPMC hauv cov tshuaj tua kab mob yog qhov dav thiab tsim nyog rau kev tshawb fawb thiab kev loj hlob ntxiv.
