Dab tsi yog cov txheej txheem ntawm pasting vuas? Thiab dab tsi yog qhov shortcomings?

Cov txheej txheem ntawm pasting vuas, feem ntau hu ua "txoj kev sib txuas ncaj qha" lossis "txoj kev tuab-txaj," suav nrog kev siv cov txheej tuab ntawm mortar ncaj qha mus rau hauv substrate (xws li pob zeb, cement board, lossis plaster) thiab muab cov vuas. rau hauv mortar txaj. Ntawm no yog ib qho kev piav qhia ntawm cov txheej txheem pobzeb ib txwm siv thiab nws qhov tsis zoo:

Traditional Pobzeb Pasting Method:

1. Kev npaj nto:
   • Lub substrate nto yog ntxuav, leveled, thiab primed kom zoo adhesion thiab daim ntawv cog lus lub zog ntawm lub mortar txaj thiab cov vuas.
2. Mixing mortar:
   • Ib qho sib tov sib xyaw uas muaj cov cement, xuab zeb, thiab dej yog npaj rau qhov xav tau sib xws. Qee qhov kev hloov pauv tuaj yeem suav nrog kev sib ntxiv ntawm cov khoom siv los txhim kho kev ua haujlwm, tuav dej, lossis cov khoom ua kom zoo.
3. Kev siv mortar:
   • Lub mortar yog thov mus rau lub substrate siv ib tug trowel, kis tusyees los tsim ib tug tuab, uniform txaj. Lub thickness ntawm lub mortar txaj yuav txawv nyob ntawm seb qhov loj thiab hom ntawm cov vuas, feem ntau yog li ntawm 10 hli mus rau 20 hli.
4. Embedded Vuas:
   • Cov vuas yog nruj nreem nias rau hauv lub mortar txaj, xyuas kom tag nrho kev sib cuag thiab kev pab them nqi. Pobzeb spacers tuaj yeem siv los tswj qhov sib txawv ntawm cov vuas thiab ua kom yooj yim rau daim ntawv thov grout.
5. Setting thiab Curing:
   • Thaum cov vuas tau teem rau hauv qhov chaw, mortar raug tso cai kho thiab tawv dhau lub sijhawm. Kev kho kom zoo (kub, av av) yog khaws cia los txhawb kev pom kev sib raug zoo thiab ua haujlwm ntev.
6. Grouting Joints:
   • Tom qab lub mortar tau kho lawm, cov pobzeb pobzeb yog ntim nrog grout siv lub grout ntab los yog squeegee. Tshaj grout yog wiped tawm ntawm cov pobzeb nto, thiab cov grout yog sab laug los kho raws li cov chaw tsim tshuaj paus cov lus qhia.

Shortcomings of Traditional Vuas Pasting Method:

1. Lub sij hawm installation ntev:
   • Cov txheej txheem tuab-txaj yuav tsum tau siv sijhawm ntau thiab ua haujlwm piv rau cov txheej txheem kev teeb tsa pobzeb niaj hnub, vim nws muaj ntau yam kev sib xyaw xws li kev sib tov sib xyaw, siv tshuaj khib nyiab, embed vuas, kho, thiab grouting.
2. Cov khoom siv nce ntxiv:
   • Cov txheej tuab ntawm mortar siv nyob rau hauv cov txheej txheem ib txwm siv yuav tsum muaj qhov ntim loj ntawm mortar sib tov, ua rau cov khoom siv ntau dua thiab cov khoom pov tseg. Tsis tas li ntawd, qhov hnyav ntawm lub mortar txaj ntxiv load rau cov qauv, tshwj xeeb tshaj yog nyob rau hauv high-sawv vaj tse.
3. Muaj peev xwm rau Bond Failure:
   • Kev npaj tsis tsim nyog los yog tsis txaus mortar npog tuaj yeem ua rau tsis zoo ntawm cov vuas thiab cov substrate, uas ua rau kev sib khi tsis ua haujlwm, pobzeb detachment, lossis tawg thaum lub sijhawm.
4. Tsawg Flexibility:
   • Lub txaj tuab tuab yuav tsis muaj qhov hloov pauv thiab tsis tuaj yeem ua raws li kev txav los yog kev sib haum xeeb hauv lub substrate, ua rau tawg lossis tawg hauv cov vuas lossis cov pob qij txha.
5. Nyuaj hauv Kev Kho:
   • Kev kho lossis hloov cov vuas ntsia siv cov txheej txheem ib txwm tuaj yeem nyuaj thiab siv sijhawm, vim nws feem ntau yuav tsum tau tshem tawm tag nrho cov mortar txaj thiab rov txhim kho cov vuas tshiab.

thaum cov txheej txheem pobzeb ib txwm siv tau ntau xyoo thiab tuaj yeem muab cov kev txhim kho ruaj khov thaum ua tiav, nws muaj ntau qhov tsis zoo piv rau cov txheej txheem niaj hnub pobzeb xws li nyias-set mortar lossis pobzeb adhesives. Cov txheej txheem niaj hnub no muab kev txhim kho sai dua, txo cov khoom siv, txhim kho kev yooj yim, thiab kev ua tau zoo dua hauv ntau yam txheej txheem substrate.
