Txheej Pem Teb
Cov txheej hauv pem teb yuav tsum muaj tsib yam ntxwv tseem ceeb tib lub sijhawm: kev nplaum zoo, kev tiv taus hnav zoo heev, kev tiv taus dej zoo, kev tiv taus kev cuam tshuam zoo, thiab kev phooj ywg ib puag ncig yam tsis muaj tshuaj lom, txhawm rau kom ua tau raws li qhov xav tau ntawm kev taug kev txhua hnub, kev ntxuav, kev cuam tshuam ntawm cov khoom hnyav, thiab kev siv mus sij hawm ntev.
Cov xim pleev hauv pem teb yog cov khoom siv saum npoo uas cuam tshuam ncaj qha rau kev taug kev ntawm tib neeg, kev txav mus los ntawm rooj tog, kev ntxuav thiab yaug, thiab kev hloov pauv ib puag ncig. Tsis zoo li cov xim pleev rau phab ntsa lossis qab nthab, lawv cov kev xav tau kev ua haujlwm ua rau muaj kev cuam tshuam ntau dua rau lub zog ntawm lub cev thiab kev hloov pauv ib puag ncig. Cov hom tseem ceeb suav nrog cov xim pleev hauv pem teb uas yog dej, cov xim pleev hauv pem teb epoxy, cov xim pleev polyurethane uas yog dej thiab cov xim pleev cement uas yog dej, thiab lwm yam. Qhov hnyav ntawm cov yam ntxwv tshwj xeeb sib txawv nyob ntawm ntau qhov xwm txheej (xws li chav ua noj hauv tsev piv rau chav ua haujlwm hauv kev lag luam).
Cov yam ntxwv tseem ceeb ntawm kev pleev xim rau pem teb
- Kev nplaum zoo:
Yuav tsum sib txuas nrog cov alkaline substrates xws li cement mortar, zam kev tev tawm thiab tawg; tswj kev sib txuas txawm tias thaum muaj kev hloov pauv kub thiab av noo.
- Kev tiv thaiv zoo hnav:
Tiv taus kev taug kev ntev, kev rub, thiab kev sib txhuam los ntawm cov khoom siv log, nrog rau cov txheej tsis ua hmoov lossis qhia lub hauv paus; qhov yuav tsum tau ua hauv qib kev lag luam siab dua, thaum rau kev siv hauv tsev, qhov tseem ceeb yog rau kev ruaj khov txhua hnub.

Muaj peev xwm ntxuav tau ntau zaus nrog dej, tiv taus cov roj av, cov kua qaub tsis muaj zog, thiab cov alkalis tsis muaj zog, tsim nyog rau cov chaw uas muaj kev ua qias tuaj xws li chav ua noj thiab chav dej.
- Kev cuam tshuam siab:
Muaj peev xwm tiv taus cov khoom hnyav poob thiab cov cuab yeej khob yam tsis muaj kev tawg lossis kev nkag mus tob; SBS hloov kho asphalt kuj muaj peev xwm kho tus kheej, muaj peev xwm kho cov qhov me me.
- Ib puag ncig zoo thiab muaj kev nyab xeeb:
Tsis muaj cov tshuaj lom neeg xws li formaldehyde, TDI dawb, thiab cov hlau hnyav; cov khoom siv dej siv dej ua cov tshuaj diluent, tsis muaj ntxhiab tsw phem thaum lub sijhawm tsim kho, thiab VOC qis heev.
Cov xim pleev hauv pem teb tsis yog cov khoom siv yooj yim uas siv tau ib txheej xwb. Hloov chaw, lawv yuav tsum tau ua kom raug raws li cov yam ntxwv tshwj xeeb raws li qhov xwm txheej ntawm kev siv: xim pleev hauv pem teb uas yog dej yog qhov zoo rau tsev neeg (phooj ywg ib puag ncig + yooj yim siv), xim pleev hauv pem teb epoxy yog siv rau hauv thaj chaw uas muaj kev thauj khoom ntau (tsis yooj yim hnav + tsis yooj yim rau tshuaj lom neeg), thaum SBS thiab lwm cov yob tsuas yog tsim rau cov txheej txheem tsim kho uas tsis muaj dej thiab tsis tuaj yeem siv ncaj qha ua cov xim tiav hauv pem teb.
Rau cov chav ua noj hauv tsev thiab chav dej, vim lawv qhov me me, ntau lub ces kaum, thiab qhov xav tau vuas, cov tshuaj pleev xim polymer raws li cement yog qhov tsim nyog dua; thaum nyob rau hauv cov chaw lag luam, epoxy lossis polyurethane systems yog qhov zoo dua.
Peb yam ntxwv tseem ceeb ntawm cov xim pleev hauv pem teb
- Kev hnav tsis kam siab:
Cov xim hauv pem teb muaj kev tiv thaiv kev hnav zoo heev, uas tuaj yeem tiv thaiv kev hnav thiab khawb ntawm hauv av. Nws yog qhov tsim nyog rau cov chaw muaj neeg coob xws li cov khw loj, cov tsev ua haujlwm, thiab cov chaw tsim khoom, yog li ua rau lub neej kev pabcuam ntawm hauv av ntev dua, txo qhov zaus ntawm kev saib xyuas thiab hloov pauv, thiab txo tus nqi saib xyuas.
- Kev tiv thaiv tshuaj lom neeg zoo:
Cov xim pleev hauv pem teb muaj kev tiv thaiv tshuaj lom neeg zoo heev, muaj peev xwm tiv taus kev yaig ntawm ntau yam tshuaj lom neeg. Nws yog qhov tsim nyog rau kev siv hauv cov chaw tsim khoom, chaw soj nstuam, tsev kho mob thiab lwm qhov chaw, tiv thaiv kev xeb thiab kev puas tsuaj ntawm cov tshuaj lom neeg rau hauv pem teb, thiab tiv thaiv kev ncaj ncees thiab kev zoo nkauj ntawm hauv pem teb.
- Kev tiv thaiv plua plav thiab dej noo zoo heev:
Cov xim pleev hauv pem teb muaj cov yam ntxwv zoo heev rau kev tiv thaiv plua plav thiab dej noo, txo cov hmoov av thiab dej noo rau hauv pem teb. Nws tsim nyog rau cov chaw uas xav tau kev huv si xws li cov chaw tsim khoom siv hluav taws xob, cov chaw tsim tshuaj, thiab cov chaw ua zaub mov, tswj kev huv thiab qhuav ntawm pem teb thiab muab ib puag ncig ua haujlwm zoo.
Tsis tas li ntawd xwb, xim pleev hauv pem teb kuj muaj cov yam ntxwv ntawm kev zoo nkauj thiab siv tau yooj yim, thiab yooj yim rau kev tsim kho. Nws haum rau ntau qhov chaw sab hauv tsev thiab sab nraum zoov. Cov kev xav tau kev txawj rau cov neeg ua haujlwm tsim kho tsis siab. Piv txwv li, thaum siv cov xim pleev hauv pem teb epoxy uas yog dej, cov cuab yeej tsim kho tuaj yeem ntxuav ncaj qha nrog dej, uas txuag lub sijhawm thiab kev siv zog thiab txhim kho kev ua haujlwm ntawm kev tsim kho.
