Cov roj hmab siv dua tshiab hloov kho asphalt waterproof txheej
Cov roj hmab rov ua dua tshiab uas tau hloov kho bitumen tiv thaiv dej tuaj yeem muab faib ua hom kuab tshuaj thiab hom dej emulsion raws li cov khoom sib txawv.
Cov roj hmab asphalt uas siv cov kuab tshuaj los ua cov roj hmab hloov kho tshiab yog ua los ntawm cov asphalt rov ua cov khoom hloov kho, roj av ua cov kuab tshuaj, ntxiv lwm cov khoom sau xws li talc, calcium carbonate, thiab lwm yam, tom qab cua sov thiab do. Qhov zoo yog tias nws txhim kho qhov yooj ywm thiab ruaj khov ntawm cov txheej txheem dej asphalt, thiab muaj ntau yam khoom siv raw, pheej yig, thiab yooj yim tsim. Txawm li cas los xij, vim yog siv roj av ua cov kuab tshuaj, yuav tsum tau them sai sai rau kev tiv thaiv hluav taws thiab cua thaum lub sijhawm tsim kho, thiab ntau daim duab yuav tsum tau ua kom zoo dua. Nws yog qhov tsim nyog rau kev tiv thaiv kev seepage, noo noo-pov thawj, tsis muaj dej ntawm cov tsev lag luam thiab pej xeem, pas dej hauv qab nthab, choj, culverts thiab lwm yam haujlwm, nrog rau kev saib xyuas cov ru tsev qub.
Cov roj hmab rov ua dua tshiab uas hloov kho bitumen dej emulsion yog tsim los ntawm anionic regenerated latex thiab anionic bitumen latex. Cov khoom me me ntawm cov roj hmab rov ua dua tshiab thiab roj av bitumen tau tawg mus rau hauv dej thiab tsim los ntawm kev ua haujlwm ntawm anionic surfactants. Cov txheej no siv dej ua cov khoom tawg, thiab muaj qhov zoo ntawm tsis muaj tshuaj lom, tsis muaj ntxhiab, thiab tsis kub hnyiab. Nws tuaj yeem siv txias ntawm chav tsev kub thiab tuaj yeem siv rau ntawm qhov chaw ntub me ntsis yam tsis muaj dej ntws. Cov txheej no feem ntau yog lined nrog cov ntaub iav fiber lossis cov khoom siv fiber ntau los ua ib txheej dej tsis nkag, thiab ntxiv cov caulking paste thaum lub sijhawm tsim kho kom ua tiav cov txiaj ntsig zoo dua. Cov txheej no yog tsim rau kev tiv thaiv dej ntawm cov ru tsev pob zeb ntawm cov tsev lag luam thiab pej xeem; kev tiv thaiv dej ntawm cov ru tsev rwb thaiv tsev thermal nrog asphalt perlite ua rwb thaiv tsev thermal; kev tiv thaiv dej ntawm cov tsev pob zeb hauv av, kev kho dua tshiab ntawm cov ru tsev linoleum qub, thiab kev saib xyuas cov ru tsev ruaj khov uas tiv thaiv dej.
Dej emulsion hom neoprene roj hmab asphalt waterproof txheej
Cov txheej txheem dej-emulsion chloroprene roj hmab asphalt tiv thaiv dej yog tsim los ntawm cationic chloroprene latex thiab cationic asphalt emulsion. Nws yog ua los ntawm chloroprene roj hmab thiab petroleum asphalt particles. Nws yog tsim los ntawm kev sib xyaw ua ke hauv dej nrog kev pab los ntawm cationic surfactants. Ib hom txheej txheem dej emulsion hom tiv thaiv dej.
Vim yog kev hloov kho nrog neoprene, cov txheej txheej muaj ob qhov zoo ntawm neoprene thiab asphalt. Nws muaj kev tiv thaiv huab cua zoo thiab kev tiv thaiv corrosion, siab elasticity, extensibility thiab adhesion, thiab muaj zog adaptability rau deformation ntawm lub hauv paus txheej. , Cov zaj duab xis txheej kub qis tsis brittle, kub siab tsis ntws, cov zaj duab xis txheej yog ntom thiab tiav, thiab dej tsis kam zoo. Ntxiv mus, cov dej-emulsion neoprene roj hmab asphalt xim siv dej ua cov kuab tshuaj, uas tsis tsuas yog muaj tus nqi qis, tab sis kuj muaj qhov zoo ntawm tsis muaj tshuaj lom, tsis-flammable, thiab tsis-ib puag ncig pa phem thaum lub sijhawm tsim kho.
Nws yog qhov tsim nyog rau kev tiv thaiv dej ntawm lub ru tsev, kev tiv thaiv dej ntawm phab ntsa thiab kev tiv thaiv dej hauv pem teb ntawm cov tsev lag luam thiab pej xeem, kev tiv thaiv dej hauv qab nthab thiab cov kav dej ntawm cov khoom siv, thiab kuj tsim nyog rau kev kho thiab kho cov dej xau ntawm cov tsev qub.
SBS roj hmab hloov kho asphalt txheej tiv thaiv dej
SBS hloov kho asphalt waterproof txheej yog ib hom dej-emulsion elastic asphalt waterproof txheej uas muaj asphalt, roj hmab SBS resin (styrene-butadiene-styrene block copolymer) thiab surfactants thiab lwm yam khoom polymer. Qhov zoo ntawm cov txheej no yog qhov yooj ywm zoo hauv qhov kub qis, tiv taus tawg, ua haujlwm zoo heev, thiab tiv taus kev laus. Nws yog sib xyaw nrog cov ntaub iav fiber thiab lwm yam khoom siv reinforced. Nws muaj kev ua haujlwm zoo tiv thaiv dej thiab siv tau rau kev ua haujlwm txias. Nws yog ib qho txheej tiv thaiv dej nruab nrab zoo tagnrho.
Haum rau kev tsim kho tsis muaj dej thiab tsis muaj dej noo ntawm cov hauv paus nyuaj, xws li chav dej, qab nthab, chav ua noj, pas dej ua ke, thiab lwm yam, tshwj xeeb tshaj yog haum rau cov haujlwm tiv thaiv dej hauv thaj chaw txias
