Kev Lag Luam Khoom Siv Hauv Tsev Lub Tsib Hlis Kev vam meej nce txhua hli, Kev thov rau cov khoom siv rwb thaiv tsev kub uas tiv taus hluav taws nthuav dav tas li
Cov ntaub ntawv hais txog kev lag luam khoom siv hauv tsev rau lub Tsib Hlis 2026, uas SASAC thiab Tuam Tshoj Lub Tsev Khoom Siv Federation tau tshaj tawm ua ke, qhia tau tias qhov ntsuas kev vam meej ntawm kev lag luam tau nce mus txog 100.8. Qhov no tau cim qhov nce txhua hli ntawm 2.3 cov ntsiab lus, rub tag nrho cov kev lag luam rov qab mus rau thaj chaw nthuav dav. Cov qauv tshiab hauv tebchaws rau kev nyab xeeb hluav taws hauv tsev thiab kev tshaj tawm tag nrho ntawm 2025 tsab Code rau Cov Khoom Siv Rwb Thaiv Tsev Thermal tau tsa qhov kev thov ruaj khov rau cov khoom rwb thaiv tsev thermal thiab cov khoom siv fiber ntau. Raws li cov khoom siv rwb thaiv tsev thermal Class A1 uas tsis kub hnyiab, cov ntaub plaub pob zeb tau pom kev thov kev lag luam nce siab thiab muaj zog loj hlob hauv nws qhov kev lag luam tshwj xeeb.
1. Kev Muab Khoom thiab Kev Xav Tau ntawm Kev Lag Luam: Rov Qab Tau Kev Tsim Khoom thiab Maj Mam Txhim Kho Kev Xav Tau ntawm Kev Lag Luam
Kab 100-point ua lub hauv paus tseem ceeb rau qhov ntsuas kev vam meej. Lub Tsib Hlis pom kev rov zoo tib lub sijhawm ntawm ob sab kev muab khoom thiab kev thov ntawm cov ntaub ntawv tsim kho. Cov ntsuas kev tsim khoom sawv ntawm 101.0, nce 2.6 hli-rau-hli thiab rov qab tsim khoom mus rau thaj chaw nthuav dav. Cov ntsuas nqi tau poob qis 0.3 hli-rau-hli mus rau 99.8, ua rau cov nqi tag nrho ntawm cov khoom lag luam nyob rau theem qis. Cov lej los ntawm Lub Chaw Haujlwm Saib Xyuas Kev Txheeb Xyuas Hauv Tebchaws taw qhia rau kev rov zoo ntawm cov khoom lag luam hauv kev lag luam hauv lub Tsib Hlis. Kev poob qis txhua xyoo ntawm cov khoom lag luam cement tau txuas ntxiv nqaim, uas qhia txog kev rov zoo qeeb hauv kev thov kev tsim kho hauv qab. Lub caij no, cov ntsuas kev thov peev txheej ntawm cov ntaub ntawv tsim kho tau mus txog 101.9, qhia txog kev txhim kho meej meej hauv kev thov kev tsim kho. Kev txo qis kev nyuaj siab rau kev siv khoom lag luam ua ke ua rau kev lag luam khoom siv hauv tsev sov.
2. Cov Nqe Khoom: Kev Sib Txawv ntawm Cov Chaw Pom Tseeb, Tus Nqi Siab Dua rau Cov Khoom Siv Thermal Insulation Fiber
Qhov sib txawv ntawm cov nqi ntawm cov khoom siv hauv tsev sib txawv tau nthuav dav thaum lub Tsib Hlis, nrog rau tus nqi ntawm cov khoom siv hauv tsev tag nrho poob qis 0.2% txhua hli. Cov khoom ib txwm muaj xws li cement thiab iav tiaj tus tau poob qis, thaum cov khoom siv phab ntsa, cov khoom tsis muaj dej thiab cov khoom siv fiber ntau tau nce nqi txhua hli. Cov nqi ntawm cov khoom siv hauv tsev poob qis 5.9% txhua xyoo txij lub Ib Hlis mus txog lub Plaub Hlis, nrog rau cement poob qis 17.2% thiab iav tiaj tus poob qis 15.1% txhua xyoo. Vim muaj kev thov nruj ntawm txoj cai, cov ntaub plaub pob zeb thiab lwm yam khoom siv rwb thaiv tsev uas tiv taus hluav taws tau tswj hwm tus nqi ruaj khov thiab muaj peev xwm tiv taus kev hloov pauv ntawm tus nqi hauv khw.
3. Kev Ua Haujlwm Zoo: Tag Nrho Lub Tuam Txhab Ntsib Kev Nyuaj Siab, Cov Khoom Siv Rwb Thaiv Kub Tau Los Ua Qhov Chaw Ci Nrov Tshaj Plaws
Cov lag luam loj hauv tsev cov khoom siv hauv tsev tau ntsib teeb meem kev ua haujlwm txij lub Ib Hlis mus txog lub Plaub Hlis. Cov nyiaj tau los ntawm kev ua haujlwm tau poob qis 14.6% xyoo-rau-xyoo, thiab tag nrho cov nyiaj tau los poob qis 74.5% xyoo-rau-xyoo. Txawm li cas los xij, kev ua tau zoo sib txawv ntawm cov sub-sectors. Rau pawg niche coj los ntawm thermal rwb thaiv tsev thiab cov khoom siv fiber ntau tau txais kev loj hlob zoo xyoo-rau-xyoo, sawv tawm ntawm kev lag luam poob qis. Iav fiber thiab kev tsim khoom siv tshwj xeeb kuj tau sau npe kev loj hlob ntawm cov nyiaj tau los xyoo-rau-xyoo. Q1 2026 cov ntaub ntawv nyiaj txiag ntawm cov tuam txhab khoom siv hauv tsev teev npe tau ua pov thawj qhov kev sib txawv no. Thaum cov nyiaj tau los tag nrho hauv kev lag luam tau qis me ntsis, cov nyiaj tau los tau zoo xyoo-rau-xyoo, nrog rau cov khoom siv hauv tsev, iav fiber thiab cov khoom siv rwb thaiv tsev kub uas tiv taus hluav taws ua cov neeg pab txhawb nqa loj.
4. Kev Lag Luam Yav Tom Ntej & Kev Hloov Kho Tshiab ntawm Lub Tuam Txhab
Cov ntaub ntawv tag nrho ntawm kev lag luam qhia tau hais tias cov khoom siv hauv tsev tseem tab tom poob qis, nrog rau kev vam meej tam sim no tsis zoo dua li lub sijhawm tib yam ntawm xyoo tas los. Txawm li ntawd los, cov cai tswjfwm hluav taws hauv tsev thiab kev txhawb nqa thoob plaws lub tebchaws ntawm cov tsev ntsuab uas siv hluav taws xob tsawg heev yuav tshem tawm cov khoom rwb thaiv tsev uas tsis yooj yim hlawv. Qhov no yuav ua rau kev thov khoom siv rwb thaiv tsev Class A1 uas tsis yooj yim hlawv thiab tswj hwm lub hauv paus ruaj khov rau kev lag luam pob zeb wool mus sij hawm ntev.
Txawm hais tias muaj lub cib fim ua lag luam raws li txoj cai no, Tianjin Jinsimai Building Materials Technology Co., Ltd. tsim thiab tsim cov khoom siv rwb thaiv tsev uas tiv taus hluav taws kub hauv nws lub npe Xiaolong. Nws cov khoom siv rwb thaiv tsev, cov kav dej rwb thaiv tsev thiab cov ntaub rwb thaiv tsev ua tau raws li txhua qhov yuav tsum tau ua hauv tsab cai Code rau Cov Khoom Siv rwb thaiv tsev xyoo 2025. Txhua yam khoom muaj daim ntawv pov thawj A1 uas tsis kub hnyiab, tiv taus qhov kub siab tshaj 1000°C, thiab muaj qhov thermal conductivity ntawm ≤0.040 W/(m·K) ntawm qhov kub nruab nrab ntawm 25°C. Lawv muab kev ua tau zoo hauv kev tiv taus hluav taws, rwb thaiv tsev thiab nqus suab. Cov khoom siv rwb thaiv tsev no siv dav rau kev rwb thaiv tsev phab ntsa sab nraud ntawm cov tsev siab, kev tiv thaiv hluav taws ntawm cov qauv hlau, kev khaws cia cua sov rau cov kav dej kub siab hauv kev lag luam thiab kev qhwv rau cov khoom siv tshwj xeeb. Txog tam sim no, lawv tau siv rau hauv ntau lub tsev nyob, Hoobkas thiab cov nroog txhawb nqa kev rwb thaiv tsev thiab cov haujlwm tiv taus hluav taws kub thoob plaws thaj tsam Beijing-Tianjin-Hebei. Lub tuam txhab khiav lub kaw lus khaws khoom loj, thiab cov qauv txheem tuaj yeem xa tuaj tsis pub dhau 3 hnub ua haujlwm. Tom qab ua tiav kev tsim kho lag luam hauv tsev thiab txawv teb chaws, lub tuam txhab muab ntau yam haujlwm engineering thoob ntiaj teb nrog cov khoom zoo ruaj khov thiab kev txhawb nqa tag nrho. Nws xa cov ntaub ntawv rwb thaiv tsev pob zeb ua raws li txoj cai, ua tau zoo los txhawb kev hloov pauv ntawm kev tsim kho mus rau kev nyab xeeb dua, txuag hluav taws xob thiab txo cov pa roj carbon dioxide.
