Dab tsi yog ib qho tshuaj sealant rau cov pob zeb ua vaj tse?
- Cov tshuaj uas nkag mus rau hauv cov pob zeb ua ke yuav cuam tshuam nrog cov cement semi-hydrated, calcium dawb, silicon oxide thiab lwm yam khoom uas muaj nyob hauv cov pob zeb ua ke hauv ntau yam tshuaj lom neeg sib xyaw ua ke los tsim cov khoom tawv.
- Cov calcium dawb, silicon oxide thiab lwm yam khoom muaj nyob rau hauv cov pob zeb tom qab ntau yam tshuaj lom neeg sib xyaw ua ke, ua rau muaj cov khoom tawv, cov tshuaj lom neeg no thaum kawg yuav ua rau qhov chaw ntawm cov pob zeb nce ntxiv, yog li ua kom lub zog, qhov nyuaj thiab qhov nyuaj ntawm cov pob zeb.
- Cov tshuaj no thaum kawg yuav txhim kho qhov compactness ntawm cov txheej txheem saum npoo av, yog li txhim kho lub zog, qhov nyuaj, kev tiv thaiv kev sib txhuam, kev tsis nkag thiab lwm yam cim ntawm cov txheej txheem saum npoo av.
Scope ntawm daim ntawv thov
- Siv rau sab hauv tsev thiab sab nraum zoov pob zeb diamond xuab zeb hnav-resistant pem teb, terrazzo pem teb, thawj slurry polished pem teb;
- Pem teb tiaj tiaj heev, pem teb cement ib txwm muaj, pob zeb thiab lwm yam khoom siv hauv paus, tsim nyog rau cov chaw ua haujlwm hauv Hoobkas;
- Cov chaw khaws khoom, cov khw muag khoom loj, cov chaw nres nkoj, cov kev khiav ntawm tshav dav hlau, cov choj, cov kev loj thiab lwm qhov chaw uas siv cov cement.
Cov yam ntxwv ntawm kev ua tau zoo
- Sealing thiab dustproof, hardened thiab hnav-resistant;
- Kev tiv thaiv kev yaig tshuaj lom neeg;
- Kev ci ntsa iab
- Kev ua tau zoo tiv thaiv kev laus;
- Kev tsim kho yooj yim thiab cov txheej txheem zoo rau ib puag ncig (tsis muaj xim thiab tsis muaj ntxhiab);
- Txo cov nqi kho, kev tsim kho ib zaug xwb, kev tiv thaiv mus sij hawm ntev.
