Polyurea - yog dab tsi? Polyurea waterproofing

Txhais tau tias kev sib khi coatings thiab yam ntxwv hais tau ntev lawm muab faib ua ob pawg: yam thiab hluavtaws cov ntaub ntawv. Oddly txaus, hnub no tseem muaj chav tsev rau ib tug tej yam ntuj tso raw khoom, uas yog superior rau hluavtaws cov ntaub ntawv uas nws ua tau zoo. Tab sis kuj nrog cov neeg sawv cev ntawm cov khoom cua hloov rau tsoos ntaub ntawv muaj ntau ntau yam tsim nyog xaiv. Nyob rau hauv no series sawv thiab Polyurea. Yuav ua li cas yog nws thiab yog vim li cas nws yuav tsum tau - cov lus nug rau ib tug ntev lub sij hawm yog tsis tseem ceeb rau kev builders, tab sis yooj yim sau yuav tsum to taub lawv nyob rau hauv kom meej. Vim lub cim qualities ntawm no hluavtaws cov ntaub ntawv uas yuav ua rau nws tau mus ua high-zoo rwb thaiv tsev, hloov feem ntau ntawm cov paub cov cuab yeej ntawm cov pab pawg neeg.

General ntaub ntawv hais txog Polyurea

Material yog ib tug hluavtaws polymer thiab nws cov qauv tsa polyurethanes, uas yog tsim los ntawm copolymerization ntawm diisocyanates. Tseeb, nkag mus rau hauv cov pab pawg neeg ntawm elastomers thiab determined qualities muaj Polyurea. Yuav ua li cas yog nws los ntawm tus taw tes ntawm view ntawm cov tswv yim daim ntawv thov? Tus thawj cov ntaub ntawv uas muaj peev xwm sawv ntawm txoj kev ua ib khoom thiab check txheej. Tus nqi ntawm cov tshuaj tiv thaiv rejection yog heev siab heev, txawm li cas los, rau qhov siv thiab ua molding khoom yuav tsum tau los mus ua kom ntxiv hauj kev kho me ntsis.

Lwm feature ntawm cov khoom cua cov ntaub ntawv uas vim lub high nucleophilicity ntawm amines. Qhov no txhais tau tias cov qauv ntawm lub tiav lawm cov khoom tsawg rhiab rau dej. Nws yog ib qhov yam ntxwv, thiab nrhiav ib qhov tseem ceeb paub tab uas yog siv nyob rau hauv kev tsim kho ntawm Polyurea txheej - waterproofing.

ntawm ntau yam Polyurea

Ib tug yuav hais tias tag nrho lub pab pawg neeg ntawm cov khoom cua polymers sib thooj, thiab nyob rau hauv tej kev txiav txim tej zaum yuav hloov txhua lwm yam. Txawm li cas los, nyob rau hauv Polyurea, muaj ob fundamentally sib txawv subspecies: lub aliphatic thiab uas muaj ntxhiab tebchaw. Tus thawj variant yog nthuav nyob rau hauv uas nws muaj peev xwm yuav siv tau los tsim UV resistant txheej. Xws li ua Polyurea nyob rau hauv daim ntawv ntawm cov txheej tsis yog deformed thiab tsis poob nws cov xim nyob rau hauv tus ntawm tshav ntuj.

Qhov thib ob hom - uas muaj ntxhiab Polyurea uas yuav suav hais tias raws li ib tug ntau yam khoom. Yog li, yog hais tias tus aliphatic feem ntau haum txheej los tiv thaiv lub-ru tsev, qhov no embodiment yog haum rau lub waterproofing ntawm lub hauv paus, thiab raws li ib tug txhais tau tias ntawm kho ornamental chaw sab hauv tsev. Nyob rau hauv tas li ntawd, lub Polyurea waterproofing yog siv niaj hnub no rau zus tau tej cov khoom thiab cov tsheb, raws li zoo raws li nyob rau hauv cov creation ntawm resistant tiv thaiv tej kev hydro noj thiab cov chaw.

Ib-tivthaiv thiab ob-tivthaiv

Rau ib tug to taub txog kev sib ncaim no yuav tsum tau ua mus rau lub hauv paus ntsiab lus ntawm cov Polyurea cov tshuaj tiv thaiv. Tus txheem cov ntaub ntawv uas yog ib tug ob-tivthaiv muaj pes tsawg leeg, uas ua nyob rau hauv tus ntawm ib lub hauv paus. Hais tias yog, tus solidification txheej txheem yuav siv sij hawm qhov chaw los ntawm txoj kev ib tug pab tivthaiv. Tam sim no nws yog tsim nyog nyob rau cov nqe lus nug ntawm yog dab tsi yog ib tug hluas-tivthaiv Polyurea. Yuav ua li cas yog nws nyob rau hauv tus txheej txheem ntawm waterproofing coatings? Nws yog yooj yim los mus thov cov ntaub ntawv uas, tsis yuav tsum tau ib lub hauv paus rau cov tshuaj tiv thaiv, piv txwv li, lub crystallization yog nqa tawm ntawm nws tus kheej, uas koj yuav ua rau phau ntawv ua.

Nws yuav zoo li yooj yim rau siv laub-tivthaiv compositions yuav tsum nyob rau hauv thawj qhov chaw, thawb ntau demanding bicomponent analogue. Txawm li cas los, nyob rau hauv cov nqe lus ntawm lub dag lub zog ntawm qhov teeb meem no yog hloov nyob rau hauv kev coj rov qab. Ib-tivthaiv compositions yuav tsum tau siv raws li ib tug pab tiv thaiv, tiam sis lub luag hauj lwm rau cov zauv feem pa Polyurea yuav tsum tau mus thov. Nrog nws ob txhais tes thiab yuav tsum muaj ntaub ntawv mus rau ib tug ob-tivthaiv, cov tseem ceeb tshaj plaws - mus siv tshwj xeeb cov khoom rau lub hom phiaj no.

waterproofing technology urea

Muaj ob peb txoj kev nyob rau hauv uas no hom ntawm waterproofing yog thov. Qhov no ua basins chaw, kev sib khi hauv paus thiab ru tsev ntawm cov dej tiv thaiv. Nyob rau hauv Feem ntau, lub txheej yog thov los ntawm sputtering ib tug nyias txheej txoj kev. Txawv nyob rau hauv le caag yuav yog vim muaj cov uas yuav tsum tau ntawm loads nyob rau hauv lub hau, lwm influences, thiab thiaj li cov neeg kawm ntawv ntawm adhesion. D. Ib zaug ntxiv, waterproofing Polyurea tej zaum yuav tau siv ib zaug xwb los yog ob tug-tivthaiv compositions. Nyob rau hauv kev ua hauj lwm nrog tej khoom xws li cov me nyuam yaus thiab ru tsev lug, nws yog ntshaw kom siv ob hom txhais tau tias, txij thaum lub fore zog yam ntxwv. Tsawg resistant rau lub cev influences waterproofing yuav siv tau raws li ib tug pab tiv thaiv txheej.

phau ntawv ua

Raws li twb tau hais, rau ywj siab ua tsim ib-feem muaj pes tsawg leeg. Ua ntej lub thov cov ntaub ntawv uas yuav tsum tau diluted nrog dej Polyurea. Txawm li cas los, lub dilution yuav tsum tau ua xwb nyob rau hauv tej yam kev mob ntawm tsawg viscosity. Nyob rau hauv lwm tus neeg mob nws yog txaus los mus do cov tshuaj rau xim uniformity. Nyob rau hauv feem ntau tus neeg mob, phau ntawv daim ntawv thov Polyurea tsis yuav tsum tau kev koom tes ntawm ib tug tshwj xeeb lub cuab tam los yog lwm yam koom haum pab Cheebtsam. Nws yuav tsum tau ua ntawv thov los ntawm cov menyuam los yog txhuam. Tab sis nyob rau hauv kev ua hauj lwm nrog cov hniav hlau, nws yog advisable siv ib tug primer. Nws kuj yog siv nyob rau hauv cov kev kho mob ntawm cov iav chaw. Tom qab kawm tiav ntawm lub waterproofing yuav tsum tau tos ib hnub los npog mas yuav kis tau txaus hardness.

Ua tshwj xeeb cov khoom

Kev cob qha cov builders los npaj thiab Polyurea tsuag siv tshwj xeeb cov khoom. Nyob rau hauv kev rau cov xav tau kev pab muaj xws li chav nyob rau txau seamless insulating coatings. Feem ntau, qhov no apparatus, kev khiav hauj lwm thaum muaj kev kub siab thiab muaj peev xwm cia ib tug kaum blends zaub mov txawv rau Polyurea. Qhov tseeb qauv ntawm cov khoom rau kev thov Polyurea muab haumxeeb chav nyob rau lub tsom xam ntawm lub kho nto theem indicators sib tov, khiav meters thiab lwm yam pab kiag li lawm uas txhim khu ergonomics apparatus.

lwm yam ntaub ntawv sau npe

Lub ua ke ntawm hardness thiab kuj mus ya los ntau Polyurea. Ntawm cov hoob kawm, ua ntej ntawm tag nrho cov nws yog siv nyob rau hauv kev tsim kho thiab xov tej hauj lwm. Tab sis qhov zoo ntawm cov khoom soj ntsuam thiab shipbuilding tuam txhab uas muag, nws pib kho khw, kev pab qhauj uas yog koom nyob rau hauv kev them nyiaj yug ntawm ntau yam lug, txuas hniav thiab tso tsheb hlau luam. Tseem muaj cov kev pab cuam ntawm no cov ntaub ntawv uas raws li ib tug insulator los ntawm. Yuav kom to taub cov cuab yeej no yog ib nqi nco ntsoov cov lus teb rau lo lus nug, Polyurea - dab tsi nws yog. Qhov no, saum toj no tag nrho, fast-qhov chaw polymer, uas muab ib tug zoo kev foob thiab lub dag lub zog. Uas yog, yog hais tias tus txheej txheem raws li cov coated nto finishing txheej, ces ib tug txias choj muaj peev xwm thiab tsis nco qab txog.

xaus

Zoo li tag nrho cov niaj hnub hauj ntaub ntawv, Polyurea ua ntej ntawm competing txhais tau tias ntawm kev rho tawm rau tus nqi. Qhov no yog ib qho kim khoom, tab sis cov no muaj nqis. Ib qho ntxiv uas yog hais tias rau lwm tus siv yuav tsum tau siv manually thov Polyurea li cov purchase ntawm kim khoom yuav ua tsis tau yus tus siv ntawm no technology. Rau hauv sib piv, nyob rau hauv cov ntaub ntawv ntawm loj-scale txheej xwm tsis muaj tshwj xeeb rwb thaiv tsev napyliteley tsis ua li cas. Dosing txhais tau tias muab ib tug niaj hnub txheej, thiab yuav cawm rau cov nqi. Nws yuav tsum raug borne nyob rau hauv lub siab hais tias cov Polyurea manufacturers yog sib txawv, ntsig txog, thiab qhov kev kawm ntawm ib tug hom yuav sib txawv.
