Pob zeb qhov tsis xws luag, suav nrog qhov pores thiab tawg, txawm li cas los xij txwv nws txoj kev siv dav thiab kev nyab xeeb. Yog li, cov txheej txheem kev sib txuas tshuab tau dhau los ua qhov tseem ceeb ntawm kev ua kom muaj kev nyab xeeb thiab kev ua haujlwm ntawm kev siv pob zeb. Qhov kev xav tau ntawm cov qauv kev sib txuas ntawm cov pob zeb ntuj yuav tau tham hauv tsab xov xwm no nrog rau kev siv thiab cov txiaj ntsig ntawm epoxy cob adhesives hauv pob zeb kho kom zoo nkauj. Peb yuav tshuaj xyuas cov khoom, siv thiab hloov kho ntawm epoxy resin nyob rau hauv qhuav dai pob zeb thiab tos ntsoov rau nws txoj kev loj hlob yav tom ntej hauv architectural kho kom zoo nkauj. Kev paub tob txog cov ntsiab lus no yuav pab peb kom zoo dua siv epoxy resin adhesives los muab lub tsev lag luam nrog kev zoo nkauj dua, kev nyab xeeb dua, kev kho kom zoo nkauj zoo nkauj hauv pob zeb.
Qhov tsim nyog ntawm kev sib txuas ntawm cov pob zeb ntuj
Cov nyhuv zoo nkauj ntawm cov pob zeb ntuj yog dav qhuas, vim nws yooj yim thiab ntuj kev ntxhib los mos thiab xim, nws muab architectural kho kom zoo nkauj ib tug elegant thiab cim temperament. Lub pob zeb ntuj lub zog txo qis los ntawm nws qhov tsis xws luag, txawm li cas los xij, nrog rau qhov pores, tawg, qhov, thiab lwm yam. Cov qauv kev sib raug zoo tau dhau los ua qhov tseem ceeb los lav tag nrho kev siv pob zeb. Cov txheej txheem kev sib txuas tshuab tsis yog tsuas yog ua rau cov pob zeb tsis xws luag, tab sis kuj daws cov teeb meem xws li tsis txaus adhesion uas yuav tshwm sim los ntawm kev siv cov cement mortar, kom cov pob zeb tuaj yeem ruaj khov rau cov substrates xws li hlau thav duab. Tsis tas li ntawd muaj txiaj ntsig zoo nyob rau hauv daim ntawv thov ntawm pob zeb phab ntsa kho kom zoo nkauj yog cov qauv kev sib txuas, tshwj xeeb tshaj yog nyob rau hauv lub tsev ntawm facade thiab curtain phab ntsa. Nws txhim khu kev ncaj ncees thiab zoo li lub tsev thiab yog li pab kev tsim kho tshuab kom nce qib.
Daim ntawv thov ntawm epoxy resin adhesive nyob rau hauv structural bonding ntawm pob zeb
Epoxy resin nplaum yog siv dav hauv pob zeb kho kom zoo nkauj thiab kho dua tshiab vim nws qhov kev sib txuas zoo heev. Epoxy resin cov qauv molecular nta ntau pab pawg, suav nrog epoxy thiab hydroxyl pawg, uas muab nws zoo kawg nkaus adhesion thiab cov khoom muaj peev xwm hloov tau. Epoxy resin's colloid shrinkage tus nqi qis tom qab kho tus neeg sawv cev ntxiv, yog li nws tuaj yeem khaws cov kav ntev, huab cua tsis kam, thiab ruaj khov. Tsis tas li ntawd, epoxy resin zoo li tsim tsis muaj cov khoom lag luam thaum kho, yog li tiv thaiv cov pob zeb thib ob. Yog li, nws yog qhov tsim nyog rau kev tsim hauv ntau qhov chaw ib puag ncig, suav nrog sab nraum zoov, sab hauv tsev, thiab lwm yam kev siv sib txawv.
Qhov zoo ntawm epoxy resin nplaum
1.Excellent bonding zog: epoxy pawg, hydroxyl pawg thiab lwm pab pawg tuaj yeem tsim muaj zog intermolecular rog nrog cov ntaub ntawv xws li pob zeb thiab hlau;
2.Me me shrinkage: Lub shrinkage ntawm lub colloid thaum lub sij hawm kho yog tsuas yog 2% ~ 3%, thiab muab tub lim tuaj yeem txo ntxiv;
3. Dimensional stability: Cov qauv yog ruaj khov tom qab kev sib txuas, cov tsos zoo nkauj, thiab nws tsis yooj yim rau deform;
4. Huab cua tsis kam: Nws tuaj yeem tiv taus ntuj tsim xws li cua, av qeeg, thiab kev hloov ntawm qhov kub thiab txias;
5. Muaj zog adaptability: Nws yog qhov tsim nyog rau kev tsim kho hauv qhov chaw sib txawv yam tsis muaj qhov kub thiab txias;
6. Tsis muaj kuab paug: Tsis muaj teeb meem cov kuab tshuaj evaporate thaum lub sij hawm kho thiab tsis muaj kuab paug los ntawm cov pob zeb;
7.Widely siv: Cov khoom lag luam hauv ntau hom tuaj yeem tsim raws li pob zeb xav tau.
Disadvantages ntawm epoxy resin nplaum
1.High brittleness: Unmodified epoxy resin yooj yim tev tawm tom qab solidification;
2. Lub sijhawm siv luv luv: Epoxy resin adhesives yuav tsum tau ua kom tiav nyob rau hauv ib lub sij hawm ntawm lub sij hawm, uas yog tsis conducive rau complex tej yaam num;
3. Kev txhawj xeeb txog kev nyab xeeb: Qee cov khoom siv epoxy resin tuaj yeem tsim cov volatiles; yog li ntawd, ib tug yuav tsum tau saib xyuas tshwj xeeb rau kev tiv thaiv kev nyab xeeb.
Lub luag hauj lwm ntawm epoxy resin nplaum nyob rau hauv qhuav dai pob zeb
Txij li thaum epoxy resin nplaum yog thawj zaug ua tiav hauv German Chemical Industry Company hauv xyoo 1934, nws tau maj mam siv dav hauv kev tsim kho. Keeb kwm tsom rau kev tsim cov cement mortar ntub dej, txoj hauv kev ntub dej tau nkag mus rau "kev hloov pauv" hauv pob zeb, yog li nws hloov mus rau hauv txoj kev dai qhuav. Ntau cov khoom thiab ruaj khov, epoxy resin nplaum siv rau hauv txoj kev dai qhuav tuaj yeem ua rau lub pob zeb ywj pheej ntawm cov cement mortar, txo cov teeb meem ntawm kev ntxuav hniav dawb thiab poob los ntawm cov cement mortar. Cov nram qab no distinguishes cov txheej txheem qhuav hanging:
1.High installation zoo: Txoj kev dai qhuav qhuav siv cov khoom siv hlau los txhawb thiab tsim cov qauv khoom;
2. Kev tsim kho ceev ceev: Txoj kev dai qhuav tsis xav tau cov cement mortar thiab tuaj yeem ua kom tiav qhov chaw thiab kev sib txuas;
3. Muaj zog cua siab thiab av qeeg ua haujlwm: Hauv cov tsev siab siab, cov qauv dai qhuav yuav tsis poob vim lub tsev vibration lossis cua siab;
4. Kev saib xyuas yooj yim: Txoj kev dai qhuav qhuav yog modularized, uas yog yooj yim rau kev kho thiab hloov tom qab.
Kev sib xyaw thiab kev hloov kho ntawm epoxy resin adhesives
Epoxy resin adhesives feem ntau yog tsim los ntawm epoxy resin thiab curing agent. Diluents, fillers, toughening agents, thiab lwm yam kuj suav nrog los txhim kho kev ua haujlwm thiab tsim cov epoxy resin adhesives hloov kho kom lawv siv tau. Ntawm cov feem ntau siv modifiers yog silane coupling agents, toughening agents, thiab lwm yam. Los ntawm txoj kev ntawm cov kev hloov kho cov tswv yim, lub colloid qhov yooj thiab durability tuaj yeem txhim kho txaus kom txaus siab rau ntau qhov kev xav tau rau kev kho kom zoo nkauj pob zeb. Tshwj xeeb tshaj yog nyob rau hauv daim ntaub ntawv xws li sab nrauv phab ntsa thiab ntaub thaiv phab ntsa, hloov kho epoxy resin nplaum muaj kev ua tau zoo hauv pob zeb kho kom zoo nkauj thiab tuaj yeem muab kev txhawb nqa ntev ntev.
Yav tom ntej txoj kev loj hlob ntawm epoxy resin adhesives nyob rau hauv architectural kho kom zoo nkauj
Epoxy resin adhesives yuav them sai sai rau cov kev txhim kho yav tom ntej hauv kev lag luam kho kom zoo nkauj rau kev tsim kho, kho kom zoo nkauj thiab kev tiv thaiv ib puag ncig:
1. Kev tiv thaiv ib puag ncig: txiav kev siv cov tshuaj phom sij thiab nce kev ua haujlwm ntawm epoxy adhesives hauv kev tiv thaiv ib puag ncig;
2.Flexibility: ntxiv txhim kho yooj thiab txo brittleness los ntawm molecular qauv hloov thiab hloov kho;
3. Kev tsim kho yooj yim: txhim kho epoxy resin cov khoom uas yooj yim rau kev khiav lag luam thiab ua kom yooj yim rau kev tsim kho;
4.Enhanced huab cua tsis kam: teb rau ntau haiv neeg ntawm kev hloov pauv huab cua thiab txhim kho huab cua mus sij hawm ntev ntawm epoxy adhesives.
Cov txheej txheem sib txuas ntawm pob zeb nyob ntawm ntau yam ntawm epoxy resin nplaum. Nws txoj kev sib raug zoo zoo thiab kev hloov pauv tau txhawb txoj kev loj hlob ntawm pob zeb qhuav dai tshuab, thaum txhim kho kev zoo nkauj thiab kev tsim kho vaj tsev. Cov ntaub ntawv tshawb fawb yuav qhib tau ntau dua rau epoxy resin adhesive daim ntawv thov hauv pob zeb kho kom zoo nkauj, yog li muab kev sib txuas ntau dua rau kev lag luam hauv tsev.
