1. Pob zeb ua thiab cement - kev tshawb fawb cov ntaub ntawv
Qhov no yog qhov kev thov tshwj xeeb tshaj plaws, raws li Twin Kab rov tav tav tov ntawm kev lag luam qheb qhob cov nroj tsuag ua haujlwm), ua kom cov txiaj ntsig kev ua haujlwm tau yog tus sawv cev ntawm cov khoom lag luam tiag tiag.
Cov Qauv Ua Kom Zoo rau Cov Qauv Tsis Zoo / Concretes:
Siv los npaj cov khoom me me ntawm cug (piv txwv li, cement- sand piv cov kev ntsuam xyuas) lossis cov qhob kuaj. Cov kws tshawb nrhiav hloov kho cov sib npaug ntawm cov khoom (xis mas, dej ua, dej, {{{ing utroting tus neeg sawv cev) los kawm lawv cov teebmeem ntawm cov khoom siv:
Kev Ua Haujlwm: Kev tshuaj ntsuam fundity (poob qis, 扩展度), dej ua kom rov qab, thiab cais tawm tsam.
Cov Cuab Yeej Siv Cov Neeg Kho Tshuab: Tshuaj ntsuam xyuas lub zog compressive, lub zog yooj yim dua, thiab elastic modulus ntawm kev kho cov qauv.
Qhov ruaj khov: Kev tshuaj xyuas kev tsis txaus ntseeg, te ua kom tsis taus, thiab carbonation tsis kam.
R & D ntawm Qib Siab Maas -} Raws cov ntaub ntawv:
Qhov tseem ceeb rau kev txhim kho siab -}}} {{{{{{{{}}} reascrived qhob pob zeb (FRC). Piv txwv li:
Kev ua kom zoo dua cov tshuaj ntawm steel fibers lossis hluavtaws fibers nyob rau hauv FRC kom sib npaug ua haujlwm thiab tawv.
Kev tshuaj ntsuam cov dispersion nyhuv ntawm nano -} {} {} {3} cuam tshuam los ntawm kev sib xyaw ntxaib) ncaj qha cuam tshuam rau cov mechanical txhim kho.
2. Cov ntaub ntawv engineering
Hauv txoj kev tsim kho, Twin Kab Rov Tav Mineers yog siv los tsim kho thiab siv tau cov qauv thiab asphalt sib tov (pab los ntawm cov khoom siv tshwj xeeb).
Maas -} divilized aggregates:
Npaj cov qauv ntawm cov cement - cov ntsiab lus ruaj khov, thiab cov ntsiab lus noo noo, cais lub zog, thiab shrinkage kev ua tau zoo. Qhov no pab txiav txim siab qhov kev sib piv ntawm txoj kev ua kom sib piv rau txoj hauv kev.
Hloov asphalt sib tov:
Kev pabcuam hauv kev sib xyaw ntawm asphalt nrog cov tshuaj ntxiv (piv txwv li, cov hmoov polymers, hmoov roj hmab (piv txwv li, rov ua dua cov pob zeb sib nraus). Lub tov khoom ua kom muaj txheej txheej ntawm asphalt ntawm aghalt ntawm kev sim siab {{{{{- kub cuv tawm ntawm cov sib tov.
3. Tshuaj lom neeg thiab kev lag luam zoo
Ntxaib Kab Rov Tav Ncej yog qhov haum rau kev sib xyaw siab high {{} {{{1} {{1} {4 4} Txoj kev tsim kev txhim kho.
Txheej, inks, thiab cov nplaum:
Kuaj cov kev sib xyaw ua ke ntawm cov pigments, fillers, resins, thiab cov kuab tshuaj. Piv txwv li:
Ua kom zoo dua cov dispersion ntawm titanium dioxide nyob rau hauv dej - Ua kom ntseeg tau cov xim zoo nkauj thiab zais hwj chim.
Kev kawm txog lub sijhawm ntawm kev sib xyaw ntawm cov viscosity thiab tsev neeg lub zog ntawm epoxy cov nplaum.
Polymer composites:
Sib tov polymer matrices (piv txwv li, pp) nrog kev txhawb nqa fillers (piv txwv li cov iav dub) los ntsuas cov khoom siv txhua yam (cuam tshuam tsis kam) ntawm cov composite.
4. Kev tiv thaiv ib puag ncig thiab cov khoom pov tseg khib nyiab
Hauv kev tshawb fawb ntawm kev rov ua dua cov khoom siv siv hluav taws xob (piv txwv li cov av tshauv kom muaj cov khoom sib xyaw ua ke nrog cov khoom siv xis nyob, ua kom muaj kev ntsuas kev ua tau zoo, ua kom muaj kev ntsuas kev ua tau zoo, ua kom muaj kev ntsuas kev ua haujlwm zoo.
Khib nyiab {-} cov khoom siv tsim kho:
Piv txwv li, tsim cov cib lossis cov thaiv uas siv cov khib nyiab hauv nroog kom loj. Lub tov khoom pab txiav txim siab qhov kev tso cai tshaj plaws ntawm cov ntoo tshauv thaum tswj lub zog compressive thiab cov khoom siv ruaj khov.
Av txhim kho:
Sib tov cov neeg sawv cev (piv txwv li, txiv qaub, txiv qaub) nrog cov nyhuv muag muaj peev xwm sib txawv ntawm cov laj kab sib txawv ntawm cov qauv ntawm lub hauv paus pom.
5. Ceramic thiab Refractory Cov Khoom Siv
Hauv kev txhim kho ntawm cov ceramic slurries lossis refractable sib tov (piv txwv li cov tov khoom ua si ntawm cov khoom siv sinwing thiab cov tshuab ua haujlwm ntawm cov khoom kawg.
Refractorters Castables:
Kuaj cov kab sib xyaw ntawm alumina hmoov, silica fume, thiab dej los ua kom yooj yim heev (rau yooj yim casting) thiab siab} lub zog (tom qab tua neeg).
