Ib txoj hauv kev zoo los txhim kho kev tiv thaiv ntawm cov qauv, cov khoom siv thiab cov qauv yog kev siv cov av sib xyaw. Cov no suav nrog bituminous primer, uas tseem hu ua primer. Qhov no kuj tseem yuav suav nrog kev sib xyaw ua ke raws li polymers thiab bitumen. Xws li cov khoom sib xyaw muaj peev xwm tiv thaiv siab thiab qis viscosity. Tom qab daim ntawv thov, nws tuaj yeem tau txais qhov chaw tiv thaiv zoo, uas tuaj yeem tshem tawm ntawm microroughnesses.
Key Features
Lub hom phiaj tseem ceeb ntawm cov primer yog cov rwb thaiv tsev hauv qab daus thiab cov hauv paus pob zeb, cov kav dej thiab cov cement-sand screeds. Bituminous primer tso cai rau koj los txo qhov nqus dej rau hauv cov khoom, vim li ntawd, koj tuaj yeem txuag tau ntawm cov khoom siv hauv tsev. Hauv kev tsim cov txheej txheem ntawm primer, tag nrho cov khoom siv yog siv, ntawm lawv:
- molten bitumen;
- Yplasticizer;
Cov primer tiav lawm txawv ntawm bitumen nyob rau hauv uas nws tsis ua brittle ntawm qis kub. Primers thaum thov muab adhesion rau qhov chaw kho. siv lawvtuaj yeem siv tsis tau tsuas yog raws li kev ywj pheej rwb thaiv tsev, tab sis kuj thaum txhim kho cov ntaub ntawv dov. Nyob rau hauv cov ntaub ntawv no, cov muaj pes tsawg leeg ua raws li ib tug nplaum pawg thiab tso cai rau koj mus muab lub seams.
Bituminous primer yog ib qho yooj yim mus use, vim hais tias nws muaj peev xwm yuav diluted mus rau lub optimum sib xws nrog dawb ntsuj plig los yog roj av. Xws li cov khoom sib tov yog muag hauv airtight tin thoob. Cov primer muaj pes tsawg leeg tuaj yeem siv tau ib nrab, thiab cov khoom sib xyaw uas tsis siv tau tuaj yeem tso tseg rau kev siv tom ntej.
Design nta
Cov lus qhia rau kev siv cov primer qhia tias kev ua haujlwm nrog nws tsis cuam tshuam txog qhov teeb meem tshwj xeeb. Nws tsuas yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias qhov zoo ntawm cov txheej yuav nyob ntawm seb qhov kev npaj saum npoo zoo li cas. Raws li cov cement-xuab zeb thiab pob zeb hauv paus, lawv yuav tsum tau muab pov tseg.
Cov primer sib tov zoo kom txog thaum tau txais homogeneous sib xws. Qhov sib tov yuav tsum tsis txhob muaj cov ntsaws ruaj ruaj thiab pob. Yog tias tsim nyog, nws tuaj yeem diluted thiab muaj zog zais ntau dua tuaj yeem ua tiav. Txhawm rau siv cov bituminous primer, siv cov menyuam txhuam los yog dav nylon txhuam.
Nyob rau hauv tus txheej txheem, koj yuav tsum tau sim ua ib txheej txawm tsis muaj smudges. Yog tias nws tsis tuaj yeem zam tau lawv, koj yuav tsum tau ua kom lawv tawm tam sim ntawd. Qhov txiaj ntsig zoo tshaj plaws yog ua tiav los ntawm kev thov los ntawm kev siv thev naus laus zis nrog kev sib kis tom qab ntawm cov muaj pes tsawg leeg ntawm qhov chaw. Nws raug pom zoo kom siv lub tshuab ntxhua khaub ncaws rau qhov no.
Cov lus qhia rau kev thov rau qhov chaw hlau
Technology rau kev siv primer rau cov hlau qhov chaw muab kev ua raws li kev ua haujlwm hauv qab no. Lub hauv paus yuav tsum tau muab ntxuav rau hlau nrog ib tug hlau txhuam. Yog hais tias nws kim heev corrosion tseem nyob tom qab no, ces yuav tsum tau siv ib tug xeb converter.
Thov los ntawm cov menyuam hauv ib lossis ntau lub tsho. Kev faib tawm ntawm bituminous primer nyob rau hauv lub polymer txheej yog nqa tawm nrog ib tug mop. Cov primer yog ua raws li lub xeev cov qauv 6617-76, tom qab nyeem ntawv uas koj tuaj yeem nkag siab tias daim ntawv thov yog nqa tawm sab nraum cov khoom lossis cov qauv hauv huab cua qhuav. Cov txheej txheem thev naus laus zis muab rau qhov xav tau los tiv thaiv qhov chaw los ntawm cov dej noo ntau dhau thaum nruab hnub, cov xwm txheej zoo li no yuav tsum tau ua raws li kom txog thaum lub npoo qhuav tag. Yog tias cov primer siv rau sab hauv tsev, yuav tsum muaj qhov cua zoo.
Nco ntsoov
Thaum siv mastic, yuav tsum tau ceev faj txog kev nyab xeeb, vim tias cov khoom muaj cov khoom sib txuas. Yog li ntawd, kev siv cov primer tsuas yog tso cai nyob deb ntawm qhov chaw qhib hluav taws thiab tsuas yog siv cov cuab yeej kev nyab xeeb ntawm tus kheej, ntawm lawv cov hnab looj tes thiab tsom iav yuav tsum tau qhia. Nws yog ib qho tseem ceeb los xyuas kom meej tias cov khoom siv tua hluav taws muaj nyob ntawm qhov chaw.
Ntau yam ntawm bituminous primers
Bituminous primer, GOST uas tau hais los saum toj no, ua lub luag haujlwm ntawm kev tiv thaiv passive. Hom rwb thaiv tsev notiv thaiv qhov chaw los ntawm lwm yam, suav nrog kev hloov pauv kub, av noo ntau dhau thiab hluav taws xob ultraviolet. Peb hom primers tam sim no paub. Ntawm lawv yog bituminous ntxhia primers, uas muaj asph alt thiab dolomite limestone, nrog rau crushed dolomite, uas ua raws li ib tug aggregate.
Bitumen-polymer primer yog hom thib ob ntawm primer, uas yog tsim nrog ntxiv ntawm hmoov los yog atactic polypropylene. Bitumen-rubber primers yog tsim los ntawm kev sib sau los ntawm cov khib nyiab roj hmab. Ntawm cov khoom xyaw no yog finely av cushioned log tsheb. Rau cov plasticity ntawm primer nyob rau hauv cov huab cua tsis zoo, plasticizers yog nkag mus rau hauv cov muaj pes tsawg leeg. Cov khoom thaum kawg tau txais qhov tsis muaj fragility.
Kev piav qhia thiab kev siv ntawm cov khoom siv roj hmab bitumen "TechnoNIKOL No. 20"
No cov roj hmab bituminous primer yog cov khoom npaj ua los ntawm cov roj av bitumen, kev pab ua haujlwm, hloov pauv polymer thiab cov ntxhia ua kua. Ntawm cov khoom xyaw yog cov kuab tshuaj organic. Tom qab ziab, cov mastic tau txais cov txheej txheem muaj zog uas tuaj yeem siv ntau qhov kub thiab txias. Qhov sib tov yog npaj rau kev kho lub ru tsev thiab kev teeb tsa ntawm mastic ru tsev, nrog rau cov txheej txheem tiv thaiv ntawm lub ru tsev thiab cov dej tsis zoo ntawm lub tsev, cov qauv thiab cov tsev.
Kev noj cov tshuaj bituminous tuaj yeem sib txawv ntawm 3, 8 mus rau5.7 kg ib sq. Yog hais tias peb tham txog lub installation ntawm ib tug waterproofing txheej, ces kev noj yuav raug txo mus rau 2.5 kg ib square meter. Qhov sib tov tuaj yeem siv tau ntawm qhov kub ntawm -20 txog +40 ° C. Hauv 24 teev, qhov sib xyaw yog khaws cia ntawm qhov kub ntawm +5 ° C. Nws yog txwv tsis pub siv nws nyob ze qhov chaw qhib hluav taws. Nws yog ib qho tseem ceeb kom ua hauj lwm nyob rau hauv intensively ventilated chav. Masters yuav tsum siv cov cuab yeej tiv thaiv tus kheej thiab tsis txhob tau txais cov primer hauv lub qhov muag thiab ntawm daim tawv nqaij.
Kev piav qhia ntawm primer "TechnoNIKOL No. 01"
Yog tias koj xav tau primer, TechnoNIKOL bituminous primer yuav yog qhov kev xaiv zoo. Nws yog npaj txhij-rau-siv formulation ntawm high quality petroleum bitumen. Qhov taw tes softening yog 70 ° C lossis ntau dua. Lub primer tso cai rau koj los npaj ib qho kev ruaj ntseg thiab txhim khu kev qha waterproofing system. Priming tso cai rau koj los ua kom cov adhesion ntawm canvas thiab waterproofing khoom rau lub hauv paus waterproofing. Qhov no tiv thaiv cov ntaub pua plag los ntawm tearing tawm nyob rau hauv cua load.
Ntawm cov txiaj ntsig ntxiv ntawm cov khoom siv yuav tsum tau qhia:
- khoom zoo;
- npaj siv;
- nrawm qhuav nrawm;
- siab nkag siab;
- muaj peev xwm siv tau ntawm qhov kub thiab txias;
- tswj kom zoo;
- kab lis kev cai ntau lawm.
Mass feem ntawm cov khoom tsis hloov pauv tuaj yeem sib npaug li 45 txog 55%. Lub sijhawm ziab yog kwv yees li 12 teev ntawm 20 teev°C Tsis muaj txawv teb chaws thiab inhomogeneous inclusions nyob rau hauv muaj pes tsawg leeg. Nominal viscosity yog los ntawm 15 mus rau 40 ° C. Ua ntej siv, primer yog tov kom txog thaum ib homogeneous loj yog tsim. Ua ntej ua tiav, qhov saum npoo yuav tsum tau ntxuav ntawm qhov seem ntawm cov dej tsis huv, xuab zeb thiab plua plav.
Zaj lus
Quality bituminous primers uas tau nteg nyob rau hauv ib tug roj hmab los yog polymer txheej yog tsim los ntawm txawv teb chaws thiab domestic hom. Muaj ntau ntau yam zoo sib xws nyob rau hauv kev ua lag luam, ntawm lawv yog cov kev xaiv uas yuav sib haum mus rau cov yam ntxwv ntawm tej qhov chaw. Bituminous txheej yog siv yooj yim heev, txawm li cas los xij, txawm li cas los xij, nws yog ib qho tseem ceeb kom ua raws li cov txheej txheem thev naus laus zis. Tsuas yog tom qab ntawd nws yuav ua tau kom ua tiav qhov txiaj ntsig zoo - txheej yuav tig mus ua ib yam, muaj zog thiab ruaj khov.
