[khoom nta]:
1. Lub zog nqus dej muaj peev xwm, tu tau yooj yim.
2. Cov khoom muag muag thiab muag muag zoo nkauj, xis thiab du, du thiab du nto, siv lub sijhawm ntev yam tsis muaj pob pilling.
3. Nws muaj zog thiab tawv, tensile thiab kua muag tiv taus, thiab nws tuaj yeem tiv taus ntau yam kev siv.
4. Nws tau ua nrog import PVA tshwj xeeb tshuab, kom nws lub zog tensile zoo dua li qhov sib txig ntxhua khaub ncaws thiab ib txoj phuam. Qhov chaw tiv tauj tsis muaj tshuaj lom thiab muaj kev phiv. Thaum nws qhuav, nws zoo li lub tawv tawv los tiv thaiv kev tawm tsam thiab tshaj tawm ntawm cov kab mob.
5. Thaum tsis siv, nws tuaj yeem ua kom qhuav tag kom tawv, kom cov kab mob tsis tuaj yeem loj hlob, thiab muag muag thaum ntsib dej.
6. Tom qab so, tsis muaj paj rwb thiab dej cim sab laug, ruaj khov.
Cov khoom lag luam:
2mm-20mm lub taub
Ntev: tuaj yeem txiav raws li cov neeg siv khoom
Lub ntsiab nta:
Cov tsos yog tsis tu ncua, tag nrho thiab dawb
Zoo elasticity, dej tsis yooj yim rau dej tom qab lub hnab ntim
The porosity yog tusyees faib; cov dej nqus yog qhov muaj zog heev, cov dej cia yog loj, thiab cov hluav taws xob tsis txav
Dej insoluble, tsis yog lo, ua kom lub tiaj ntawm dej evaporation tus nqi
Nws tuaj yeem phim txhua hom tshuaj tsw qab, ua kua thiab lwm cov kuab tshuaj dej, thiab yog tsis muaj tshuaj lom. Nws yog cov khoom ntsuab thiab ib puag ncig-phooj ywg.
