Dej tsis haum thiab Thermal rwb thaiv tsev ntaub Polyurea

Waterproof thiab thermal rwb thaiv tsev system

Thaum pib xyoo 1995, American Roofing Engineering Association (NRCA) xaus rau ntawm lub hauv paus ntawm ntau qhov kev siv tswv yim ua kom pom cov dej tsis ua haujlwm thermal rwb thaiv tsev SPUA (tshuaj tsuag polyurea elastomer) / SPUF (txau polyurethane ua npuas dej) cov qauv sib xyaw ua ke yog qhov ntev nkaus xwb- lub sij hawm ua hauj lwm zoo nyob rau hauv tag nrho cov dej tsis ua hauj lwm thiab cov cua kub rwb thaiv tsev. Tus qauv tshiab no muaj cov txiaj ntsig zoo: (1) Nws ua ke cov khoom siv dej tsis ua haujlwm thiab thermal rwb thaiv tsev, ua kom yooj yim tsim thiab kev tsim kho, thiab yooj yim tsib txheej txheem ntawm cov tsoos ru tsev thiab tiv thaiv dej, suav nrog kev sib luag, chav rwb thaiv tsev, rwb thaiv tsev thermal, tiv thaiv dej thiab kev tiv thaiv, rau hauv peb cov txheej txheem ntawm primer, thermal rwb thaiv tsev thiab dej tsis muaj pov thawj.

(2) Cov txheej yog tsis tu ncua, ua kom me me, tsis muaj kev ruaj khov thiab muaj kev ua tau zoo tshaj plaws dej, uas ua rau txoj kev ua haujlwm zoo zog tuaj.

(3) Tsis tshua muaj cov thermal conductivity thiab zoo rwb thaiv tsev thermal. Nyob hauv tib lub thickness, lub thermal tsis kam yog 10 npaug ntawm cov tsoos thermal rwb thaiv tsev ntaub, uas tuaj yeem txuag 30% rau 40% ntawm lub zog.

(4) Kev tsim kho sai heev. Kev tsim kho thaj chaw txhua hnub ntawm ib qho cuab yeej siv khoom tuaj yeem ncav cuag 1000m, uas tsis tshua muaj teeb meem huab cua ntawm kev nce qib ntawm qhov dej num.

(5) Cov khoom muaj zoo yooj, siab zog, zoo tiv laus kev laus thiab kev pab lub neej ntawm 20-30 xyoo.

(6) Lub zuag qhia tag nrho ntawm cov khoom yog me me thiab qhov hnyav yog lub teeb. Thaum lub ru tsev ntawm lub tsev qub raug tsim ua tiav, txheej txheem dej qub tsis tas yuav tsum tau muab tshem tawm, uas txuag nqi ntau.

(7) Kev nplaum zoo, tsis muaj teeb meem tias cov kauj vuam dav yog yooj yim hle thiab warp lub hauv paus cov khoom, thiab tsis muaj teeb meem tias cov txheej txheem dej dav dav yog yooj yim los dai thiab lub thickness tsis zoo li qub.

(8) Hauv kev tsim kho thiab siv, lawv tsis muaj tshuaj lom thiab muaj kuab paug, thiab paub zoo li "cov ntaub ntawv ntsuab, ntsuab thev naus laus zis".
