DDPU-301 polyurethane grouting khoom rau kev cawm thiab nyem
DDPU-301 polyurethane grouting khoom rau kev cawm thiab nyem
Taw qhia
DDPU - 301 yog ob lub ntsiab lus hydrophobic polyurethane grouting khoom, tsim los cawm thiab nyem.Cov khoom muaj lub sijhawm luv luv thiab hloov pauv sai ntawm cov kua mus rau lawv daim ntawv ua npuas kawg.Cov khoom siv no tuaj yeem tsis tsuas yog ntsaws rau hauv dej, tab sis kuj muaj qee qhov kev txhawb zog thiab ruaj khov.Nws tau dav siv nyob rau hauv subway tunnels, kev txuag dej thiab hydropower, underground garage, dej phwj tuaj thiab lwm yam teb ntawm waterproof to-plugging.
NTA
A. Ceev ceev nrog dej, ceev foaming nthuav thiab kho.Lub sij hawm cov tshuaj tiv thaiv tuaj yeem hloov kho raws li tus nqi ntawm cov tshuaj tiv thaiv A, feem ntau tuaj yeem tswj tau los kho hauv kaum vib nas this mus rau feeb.
B. Tshuaj stability zoo heev.
C. Siab zog.Lub zog compressive tuaj yeem dhau 20MPa hauv ob peb teev thaum molding nyob rau hauv airtight tej yam kev mob;
D. Nrog loj infiltration radius thiab solidification ntim piv, ceev tshuaj tiv thaiv.Thaum cov khoom ntsib dej, qhov kev nthuav dav loj yuav raug tsim los thawb lub slurry tob rau hauv qhov tawg los ua ib qho kev sib koom ua ke nyuaj.

APPLICATION
A. Seam sealing thiab waterproof anticorrosive txheej ntawm pas dej ua ke, dej ntauwd, hauv qab daus, huab cua tua vaj tse thiab lwm lub tsev;
B. Anticorrosion ntawm hlau thiab qhob kav dej thiab cov qauv hlau;
C. Kev kho plua plav, qhov av hauv av lossis lub hauv paus txhim kho;
D. Sealing thiab ntxiv dag zog rau deformation seams, kev tsim kho cov pob qij txha thiab cov kab nrib pleb hauv kev tsim kho;
E. Sealing to thiab ntxiv dag zog cov chaw nres nkoj, wharves, piers, dams thiab hydropower chaw nres tsheb;
F. Kev tiv thaiv phab ntsa thiab xau ntsaws rau hauv geological drilling, xaiv dej ntsaws rau hauv cov roj siv, thiab dej nres-gushing hauv mine, thiab lwm yam.
Ntim, Cia thiab thauj mus los
A. Cov khoom yuav tsum tau muab khaws cia rau hauv huv si, qhuav thiab airtight hlau nruas nrog ib ntim ntawm 20kg / nruas los yog 10kg / nruas;
B. Tsis txhob los nag, raug, extrusion thiab kev sib tsoo thaum lub sij hawm thauj mus los kom ntseeg tau tias lub pob nyob rau hauv zoo;
C. Cov khoom yuav tsum tau muab cia rau hauv qhov chaw cua, qhuav thiab txias kom tsis txhob tshav ntuj ncaj qha thiab los nag.Storage kub yuav tsum tsis txhob siab tshaj 40 ℃;
D. Raws li kev cia khoom ib txwm muaj, lub sijhawm cia yog 6 lub hlis
