Yuav ua li cas txheeb xyuas qhov zoo thiab qhov tsis zoo ntawm SBS waterproofing membrane?
Jun 23, 2022
Raws li lub npe qhia, asphalt hloov kho tshuab yog ntxiv ib qho ntawm cov ntaub ntawv hloov kho rau asphalt, thiab siv cov txheej txheem tshwj xeeb los hloov nws cov kev ua tau zoo kom tau raws li qhov xav tau ntawm peb cov khoom siv dej tsis zoo. Cov kev hloov kho uas nquag siv tau muab faib ua ob pawg: ib qho yog plastomer hloov asphalt, cov ntaub ntawv zoo tshaj plaws yog APP (AOAO, APO) cov ntaub ntawv hloov kho; qhov thib ob yog elastomer-hloov asphalt, uas yog hloov los ntawm ntau yam khoom siv roj hmab. Lub teb chaws tus qauv yuav tsum GB18242-2000 txhais cov ntaub ntawv elastomer-hloov asphalt waterproofing. Nws yog ib lub tsev waterproofing membrane ua los ntawm polyester log tsheb los yog iav fiber lev raws li lub log tsheb puag, styrene-butadiene-styrene SBS thermoplastic elastomer li modifier, thiab them nrog cais cov khoom ntawm ob sab, hu ua SBS coiled khoom. Nyob rau tib lub sijhawm, cov khoom sib cais saum npoo tau muab faib ua peb hom: polyethylene zaj duab xis, PE zaj duab xis, xuab zeb zoo, thiab ntxhia pellets.
Elastomer-hloov bitumen waterproofing membrane hu ua "SBS membrane" yog raws li polyester xav los yog iav fiber ntau zoo li lub hauv paus, styrene-butadiene-styrene SBS thermoplastic elastomer li modifier, thiab yog them nrog cais cov khoom ntawm ob sab Lub tsev tsim waterproofing. daim nyias nyias, cov khoom kos npe yog ua raws li cov txheej txheem hauv qab no, elastomer-hloov asphalt waterproofing membrane, qauv, log tsheb puag, cov khoom siv saum npoo av, thickness thiab tus qauv no. Piv txwv li: 3 hli tuab xuab zeb nto polyester log tsheb hom I elastomer hloov asphalt waterproofing membrane, cim raws li SBS I PY S3 GB18242. Cov plastomer hloov bitumen waterproofing membrane yog abbreviated li "APP membrane", uas siv polyester muaj los yog iav fiber ntau zoo li lub hauv paus, random polypropylene APP los yog polyolefin polymers APAO thiab APO li modifiers, thiab yog them nrog kev sib cais ntawm ob sab. Rau lub tsev waterproofing membrane ua los ntawm cov ntaub ntawv, cov khoom kos npe yuav tsum tau ua raws li cov txheej txheem hauv qab no, plastomer hloov asphalt waterproofing membrane, qauv, log tsheb puag, cov khoom saum npoo av, thickness thiab tus qauv tooj; Piv txwv li: 3 hli tuab xuab zeb nto polyester log tsheb Hom I plastomer hloov bitumen waterproofing membrane, cim raws li APP I PY S3 GB18243.
1. Kev txheeb xyuas qhov tshwm sim
(1) Ua ntej saib seb lub ntim puas yog tus qauv, lub kauj tuaj yeem ntim rau hauv cov yob nrog daim ntawv puv-kem qhob cij lossis daim kab xev yas. Thaum ntim rau hauv daim ntawv, tag nrho cov ntim tsis ntev ntawm ob qho kawg ntawm lub tog raj kheej yuav tsum tsis pub tshaj 100mm. Muaj cov cim qhia ntawm lub ntim, thiab cov paib yuav tsum qhia cov hauv qab no: cov chaw tsim khoom lub npe, cov cim lag luam, cov khoom cim, hnub tsim khoom thiab batch naj npawb, daim ntawv tso cai ntau lawm, khaws cia thiab ceev faj txog kev thauj mus los. "Marking" yog ib qho yuav tsum tau muab, uas yuav tsum tau cim raws li txoj kev, ib theem zuj zus thiab code teev nyob rau hauv lub teb chaws tus qauv.
Txhua yob ntawm cov khoom yuav tsum raug cim, thiab yog tias tsis muaj qhov cim ntawm lub yob lossis cov ntsiab lus ntawm cov cim tsis tiav, nws yog qhov cuav.
(2) Lub sijhawm khaws cia ntawm cov khoom coiled nyob rau hauv ib txwm cia thiab kev thauj mus los yog ib xyoos txij li hnub tsim khoom. Txhua yam khoom siv coiled uas tshaj lub sijhawm cia yuav tsum tau rov tshuaj xyuas ua ntej nws tuaj yeem siv tau.
(3) Cov khoom siv coiled yuav tsum tau dov kom nruj thiab zoo zoo, thiab sab hauv thiab sab nraud ntawm lub ntsej muag kawg yuav tsum tsis pub tshaj 10mm, uas cuam tshuam rau cov kev cai ntawm cov kev cai siv lub tshuab dov tsis siv neeg. Nws tsis tuaj yeem ua tsis tau yam tsis muaj cov cuab yeej dov siab heev thiab yuav tsum raug txiav txim tias tsis tsim nyog.
(4) Lub log tsheb yuav tsum tau saturated, thiab yuav tsum tsis muaj streaks unimpregnated. Nws tuaj yeem raug txheeb xyuas los ntawm ntu ntu uas fakes feem ntau qhia cov kab dawb ntawm lub log tsheb.
(5) Saib xyuas nws cov xim, tsw nws saj, kov nws lub siab kom paub qhov tseeb thiab tsis tseeb, thiab saib nws cov xim, xim ntawm lub kauj tiag tiag yog xim dub thiab ci, thiab nws muaj feem xyuam. Vim hais tias ntawm high-shear grinder, nws muaj zoo heev khiav-nyob rau hauv compatibility thiab tsis insoluble zoo hais. Nws tuaj yeem pom meej dua los ntawm ntu coil. SBS coil cuav tsis muaj gloss dub, los yog muaj me me insoluble hais nyob rau hauv tus ntoo khaub lig seem, thiab lub kauj zoo li ntxhib. Tshav nws saj, lub kauj tiag tiag yog qhov tsis muaj ntxhiab tsw, txawm tias nws yog cua sov nrog qhov qhib hluav taws, tsuas muaj qhov tsis hnov tsw ntawm cov roj hmab hlawv. Lub kauj ua los ntawm cov roj hmab khib nyiab hmoov muaj cov ntxhiab tsw ntxhiab tsw, thiab saj yuav muaj zog dua yog tias cua sov nrog qhov qhib hluav taws. kov nws yog txiav txim siab. SBS coils yog cov mos mos thiab elastic, uas qhia tau hais tias qhov kub thiab txias tsis kam. Cov khoom cuav tsis muaj elasticity thiab yooj yim tawg.
(6) Kev txheeb xyuas lub log tsheb, kev txheeb xyuas yooj yim ntawm cov log tsheb tsis tseeb, yuav tsum muaj qee yam kev paub, feem ntau yog los ntawm kev kuaj xyuas qhov muag pom. Polyester log tsheb yog tuab dua (txog 0.8mm), muaj zog tensile siab thiab tsim kua muag lub zog, yog qhov nyuaj heev los tsim kua muag thiab tawg, thiab sib piv longitudinally thiab tom qab. Lub log tsheb hauv paus muaj kev sib raug zoo nrog asphalt, thiab nws nyuaj rau ua nws txheej. Tom qab lub log log yog torn sib nrug, tsuas muaj polyester fiber. Cov log tsheb sib xyaw ua ke feem ntau muab faib ua ob daim thaum nws tawg los ntawm txhais tes, thiab cov tav ntawm cov iav fiber ntau yog pom thaum lub log tsheb tawg. Txhawm rau kom paub tseeb tias qhov tseeb ntawm lub log tsheb hauv paus, koj tuaj yeem siv cov ntsiab lus soluble sim ua kom pom cov log tsheb raug pom los txiav txim siab.
