Yuav ua li cas
ntsuas qhov ntev ntawm qhov tawg kom paub qhov ntev ntawm qhov sib koom ua ke filling profile. Feem ntau, txoj kab uas hla ntawm tsib millimeters yog txaus rau kev kho, vim tias feem ntau kev puas tsuaj tsis dav. Yog tias qhov tawg me dua qhov muab tub lim, nthuav nws nrog lub kaum sab xis grinder lossis lub tshuab sib koom ua ke. cheb qhov sib txawv zoo nrog txhuam kom cov ntsaws ruaj ruaj kom huv si.
Repair puas:
- Pov tawg nrog PU npuas
- Nias lub sib koom sau profile ncaj qha rau hauv qhov sib txawv
- txiav tawm cov tawv nqaij ua npuas ncauj tom qab ib teev
Yuav ua li cas mus ntxiv
Ua tib zoo kaw qhov tawg ntawm phab ntsa ntawm ob sab nrog cov neeg pleev kob daim kab xev thiab txhuam cov chaw kho nrog cov nplaum nplaum.

Special filling khoom
Kev puas tsuaj me me tuaj yeem kho nrog cov khoom tshwj xeeb, kom tsis txhob muaj qhov profile ntxiv. Expodite resin seals thiab txuas cov kab nrib pleb mus txog 0.1 millimeters dav. Yog tias qhov sib txawv tsawg dua 0.2 millimeters dav, cov cement suspensions muab lub foob foob. Polyurethane resins yog siv rau kev puas tsuaj me dua 0.3 millimeters. Cov kws tshaj lij feem ntau siv cov cement slurry rau cov kab noj hniav uas muaj qhov dav tawg tsawg dua 0.8 millimeters.
