Yuav tsum tau ntxiv cellulose rau mortar thiab gypsum raws li cov khoom

Mortar thiab gypsum-raws li cov khoom lag luam yog cov ntsiab lus tseem ceeb hauv kev tsim kho kev lag luam, ua tus neeg sawv cev rau ntau yam khoom siv hauv tsev. Cov khoom no tau dhau los ua kev tsim kho tshiab thiab txhim kho kom tau raws li qhov xav tau ntawm kev tsim kho niaj hnub no. Ib qho tseem ceeb ntxiv hauv cov ntaub ntawv no yog cellulose, uas ua lub luag haujlwm tseem ceeb hauv kev txhim kho lawv cov kev ua tau zoo thiab cov khoom.

Nkag siab txog Cellulose:

Cellulose yog ib txwm tshwm sim polysaccharide pom nyob rau hauv cell phab ntsa ntawm cov nroj tsuag. Nws yog cov organic polymer ntau tshaj plaws hauv ntiaj teb thiab ua haujlwm tseem ceeb hauv cov ntaub so ntswg. Hauv tshuaj, cellulose molecules muaj cov kab sib txuas ntawm cov piam thaj txuas ua ke los ntawm β (1 → 4) glycosidic bonds. Qhov tshwj xeeb molecular qauv imparts tshwj xeeb lub zog, stability, thiab resilience rau cellulose.

Hauv kev tsim kho kev lag luam, cellulose pom ntau daim ntawv thov ua ib qho ntxiv hauv ntau yam khoom siv hauv tsev, nrog rau cov khoom siv khib nyiab thiab gypsum. Nws koom tes ua haujlwm rau ntau lub hom phiaj, hais txog ntau yam kev nyuaj uas tau ntsib thaum lub sijhawm tsim khoom, kev siv, thiab kev ua haujlwm ntawm cov khoom siv no.

Kev ua haujlwm ntawm Cellulose hauv mortar thiab Gypsum-based khoom:

Kev tuav dej:
Ib qho ntawm cov haujlwm tseem ceeb ntawm cellulose hauv mortar thiab gypsum-based khoom yog nws lub peev xwm khaws dej. Cellulose fibers muaj peev xwm nqus tau thiab tuav dej hauv lawv cov qauv. Thaum ntxiv rau cov ntaub ntawv no, cellulose ua raws li cov dej khaws cia, ua kom muaj dej txaus ntawm cov cementitious lossis gypsum Cheebtsam. Cov txheej txheem hydration ntev no txhim kho kev ua haujlwm ntawm qhov sib tov, tso cai rau kev siv zoo dua thiab txhim kho adhesion rau substrates.

Txhim kho kev ua haujlwm thiab kev sib koom ua ke:
Lub xub ntiag ntawm cellulose fibers nyob rau hauv mortar thiab gypsum-raws li cov khoom txhim khu lawv kev ua hauj lwm thiab cohesion. Cellulose fibers ua raws li tus neeg sawv cev txhawb zog, zoo dispersing thoob plaws hauv qhov sib tov thiab tsim ib lub network peb sab. Lub network no txhawb nqa cov matrix, tiv thaiv kev sib cais thiab txhim kho tag nrho cov khoom sib xws thiab homogeneity ntawm cov khoom. Raws li qhov tshwm sim, qhov sib xyaw ua kom yooj yim rau kev tuav, sib kis, thiab cov duab, ua rau kev txhim kho kev ua haujlwm zoo thaum lub sijhawm tsim kho.

Kev Tiv Thaiv Kev Tiv Thaiv thiab Kev Tiv Thaiv Shrinkage:
Lwm lub luag haujlwm tseem ceeb ntawm cellulose nyob rau hauv cov ntaub ntawv no yog nws txoj kev koom tes rau kev tiv thaiv kev tawg thiab kev tiv thaiv shrinkage. Thaum lub sij hawm ziab thiab kho, mortar thiab gypsum-raws li cov khoom raug cuam tshuam rau shrinkage thiab tawg vim tsis ya raws thiab kev ntxhov siab sab hauv. Cellulose fibers pab txo cov teeb meem no los ntawm kev muab kev txhawb zog sab hauv thiab txo qhov tsim ntawm micro-cracks. Los ntawm kev txhim kho lub zog tensile thiab ductility ntawm cov khoom, cellulose txhim kho nws cov kev tiv thaiv rau shrinkage-induced cracking, yog li txhawb lub sij hawm ntev durability thiab structural kev ncaj ncees.

Txhim kho Mechanical Properties:
Cellulose reinforcement imparts enhanced mechanical zog rau mortar thiab gypsum-based khoom. Qhov sib ntxiv ntawm cellulose fibers tsub kom cov khoom flexural thiab tensile zog, cuam tshuam tsis kam, thiab durability. Qhov kev txhim kho hauv kev ua tau zoo ntawm kev siv tshuab yog qhov tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov uas cov khoom raug cuam tshuam los ntawm cov khoom thauj, sab nraud quab yuam, lossis ib puag ncig. Los ntawm kev ntxiv dag zog rau cov matrix thiab txo qhov kev pheej hmoo ntawm kev ua tsis tiav, cellulose txhim kho tag nrho cov kev ua tau zoo thiab lub neej ntev ntawm cov qauv tiav.

Compatibility nrog Sustainable Practices:
Cellulose yog muab los ntawm cov khoom siv txuas ntxiv dua tshiab xws li ntoo pulp, paj rwb, lossis cov ntawv siv rov ua dua tshiab, ua rau nws nyob ruaj khov thiab zoo ib puag ncig. Nws siv nyob rau hauv mortar thiab gypsum-raws li cov khoom ua ke nrog kev lag luam kev loj hlob tseem ceeb ntawm kev tsim kho kom ruaj khov thiab kev tsim vaj tsev ntsuab. Los ntawm kev koom nrog cov khoom siv cellulose, cov tuam txhab lag luam tuaj yeem txo lawv qhov kev cia siab ntawm cov peev txheej tsis txuas ntxiv thiab txo qhov cuam tshuam ib puag ncig ntawm lawv cov khoom. Qhov kev sib raug zoo nrog cov kev coj ua ruaj khov no tseem qhia txog qhov tsim nyog ntawm cellulose hauv cov khoom siv niaj hnub no.

Qhov sib ntxiv ntawm cellulose rau mortar thiab gypsum-based khoom tsis yog ib qho teeb meem ntawm kev xaiv tab sis yog ib qho tseem ceeb uas tau tsav los ntawm kev xav tau kev txhim kho kev ua tau zoo, durability, thiab sustainability. Cellulose ua haujlwm rau ntau yam, suav nrog kev tuav dej, txhim kho kev ua haujlwm, tiv thaiv kev tawg, thiab kev siv dag zog. Nws cov khoom tshwj xeeb thiab kev sib raug zoo nrog cov kev coj ua kom ruaj khov ua rau nws yog qhov tseem ceeb ntxiv rau hauv cov khoom siv niaj hnub no. Raws li kev tsim kho kev lag luam txuas ntxiv mus, qhov tseem ceeb ntawm cellulose hauv mortar thiab gypsum-raws li cov khoom lag luam tsuas yog yuav loj hlob, ua rau lub neej yav tom ntej ntawm kev ua haujlwm ruaj khov thiab ua haujlwm zoo.
