Cov ntaub ntawv vov tsev yog cov khoom siv hauv tsev uas muaj ntau yam kev siv; nws yog qhov xav tau thaum tsim cov txheej txheem dej tsis sib haum thiab teeb tsa lub ru tsev. Cov txheej txheej muaj nws tus kheej cov khoom me me thiab cov npe, qhov sib txawv tseem ceeb ntawm lawv los rau qhov muaj pes tsawg leeg ntawm bitumen puag. Ib qho ntawm cov khoom siv feem ntau yog vov tsev yog RCP.
Nws sawv ntsug li cas?
Raws li tau lees paub GOST 10923-93, txhua yam khoom siv hauv tsev yuav raug rau daim ntawv lo. Nws kwv yees cov ntawv luv uas suav nrog cov ntaub ntawv yooj yim txog cov khoom lag luam tus yam ntxwv.
- Hom khoom . Thawj lub cim ntawm kev kos cim qhia txog cov txheej txheej txheej. Txhua hom khoom siv vov tsev raug xaiv los ntawm tsab ntawv "P".
-
Lub hom phiaj ntawm cov khoom . Txiav txim siab los ntawm tus cim thib ob tam sim tom qab "P":
- "P" - qhia txog pab pawg ntawm cov khoom siv sab hauv;
- "K" - hais txog cov khoom siv vov tsev, lawv xav tau thaum txhim kho sab saud ntawm "ru tsev ncuav qab zib".
-
Hom kis . Lub cim thib peb txiav txim siab txog cov yam ntxwv ntawm txheej txheej txheej ntawm cov khoom vov tsev, muaj plaub qhov kev xaiv siv:
- K - ntxhib -grained, nws yog tsim los ntawm pob zeb chips;
- M - nplua -grained, los ntawm cov xuab zeb;
- Ch - nplai, ua los ntawm mica thiab quartz;
- P - plua plav, nws yog tsim los ntawm chalk lossis talc magnesite.
- Lub hauv paus muaj zog . Tsab ntawv kawg qhia txog qhov ntom ntom ntawm cov duab los qhia rau kev tsim cov khoom vov tsev.
Tom qab cov ntawv teev tseg hauv qhov cim yog cov lej, lawv sib haum rau qhov hnyav ib square meter ntawm cov khoom, ntsuas hauv grams. Feem ntau ntawm cov txheej txheej hauv khw muaj qhov ntom ntom ntawm 200-400 g / sq. m.
Yog li, lub npe luv RCP sib raug rau "vov tsev muaj hmoov av "
Nyob ntawm seb hom ntawv los xij, nws tuaj yeem muaj qhov ntsuas 350, ntxiv rau 400 thiab 450.
Npav thiab specifications
Kev nthuav dav tshaj plaws hauv kev tsim kho qis yog cov khoom vov tsev cim RCP 350. Nws yog qhov xav tau thaum txhim kho cov tsev rau lub tsev thiab lub ru tsev tiaj tus, ntxiv rau tsim kev tiv thaiv dej. Cov khoom siv yog qhov sib txawv los ntawm cov hmoov av, thiab qhov ntom ntawm daim ntawv los hauv paus sib haum rau 350 g / sq. m. Nws yog UV-tiv taus thiab cov khoom pov thawj noo noo. Nws yog siv feem ntau rau cov txheej txheej qis ntawm cov qauv ru tsev; tso rau hauv ib sab tau tso cai tsuas yog hauv cov qauv ib ntus.
Muaj 2 qhov hloov kho ntawm cov khoom siv hauv tsev:
- RCP 350;
- RCP 350-0.
Hom thib ob ntawm cov khoom siv vov tsev yog suav tias yog lub teeb yuag, nws yog qhov txawv los ntawm cov hmoov av zoo dua raws li cov hmoov txhuv hmoov uas tsis muaj cov plua av tsis huv . Nws lub kua muag tsis kam yog qhov tsawg. Cov khoom siv no xav tau tshwj xeeb tshaj yog rau kev tsim cov dej tsis sib haum ntawm lub ru tsev tseem ceeb.
Kev hloov kho yooj yim ntawm RCP 350 muaj qhov ntom ntom ntom ntom ntom ntom thiab muaj zog, yog li nws tuaj yeem siv rau npog txheej txheej ntawm lub ru tsev . Rau kev tsim cov khoom siv hauv tsev, cov ntawv tuab tau siv, nws tau pleev xim nrog cov roj uas muaj cov tshuaj, thiab tom qab ntawd npog nrog cov cua sov tiv taus bitumen ntawm ob sab. Sprinkle talcum hmoov lossis talc magnesite rau saum. Cov thev naus laus zis no ua kom muaj kev tsim cov khoom lag luam zoo nrog kev ua haujlwm zoo dua qub. Cov khoom vov tsev RKP 350 yog ib qho yooj yim rau kev khiav lag luam, dua li, nws pheej yig: tus nqi ntawm ib yob hauv khw muag khoom yog 230-270 rubles.
Cov cuab yeej tseem ceeb yog tswj hwm los ntawm cov cai tam sim no:
- dav ntawm ib yob - 1000/1025/1050 hli;
- ntev ntawm ib yob - 15 m;
- thaj tsam ntawm ib lub yob -10 / 15 /20 sq. m.; ua.
- qhov hnyav - 2 kg / sq. m.; ua.
- Qhov siab ntawm cov khoom siv bituminous tsis tshaj 0.8 kg / sq. m.; ua.
- qhov kawg lub zog tensile - 280N;
- qhov hnyav tshwj xeeb - 0, 35–0, 4 kg / sq.m.; ua.
- tiv tshav kub - tsis qis dua 80 degrees rau 2 teev;
- tiv taus ya raws - 72 teev ntawm qhov siab tsis pub dhau 001 kgf / cm2.
Qhov txawv ntawm RPP yog dab tsi?
RCP yog ib lub ru tsev uas muaj lub ru tsev zoo nrog cov hmoov av. Hais txog nws cov txheej txheem kev ua haujlwm thiab cov yam ntxwv ua haujlwm, nws zoo ib yam li RPP 300 txheej, RPK 350A siv tsawg tsawg zaus. Cov ntaub ntawv vov tsev no yog xav tau thaum txhim kho lub ru tsev tsis muaj dej. Cov ntaub ntawv vov tsev RPP thiab RKP tau txais los ntawm kev pleev xim ntawm cov duab los qhia nrog cov bitumen sib xyaw nrog kev thov ntxiv ntawm cov hmoov av.
Txawm li cas los xij, cov yam ntxwv ntawm RCP thiab RPP muaj lawv tus kheej qhov sib txawv:
- qhov hnyav ntawm RPP 300 txheej yog 500 g / sq. m., Nws yog qhov sib zog ntau dua li RCP 350;
- rhuav lub zog - 220 N, uas tseem qis dua li ntawm RCP 350.
Tus so ntawm qhov ntsuas (yob qhov ntev, cua sov thiab dej tsis kam) yog nyob rau tib qib.
Qhov sib txawv no txiav txim siab cov yam ntxwv ntawm kev siv cov khoom siv . Ob qho tib si xav tau thaum teeb tsa kev tiv thaiv dej tsis zoo ntawm lub ru tsev. Lawv tau siv los ua ib feem ntawm "ncuav mog qab zib" rau ondulin lossis cov vuas hlau, qhov twg lub sijhawm ntawm lawv cov kev pabcuam yog li 10 xyoo. Txawm li cas los xij, RCP tuaj yeem tso ua txheej txheej rau txheej txheej ib ntus, txawm hais tias qhov no kev ua haujlwm ntawm cov khoom siv tsis pub dhau 3-5 xyoos. RPP tsis tso cai siv.
Nws siv qhov twg?
Cov khoom vov tsev RKP 350 yog xav tau thaum ua haujlwm uas cuam tshuam nrog kev kho thiab tsim lub ru tsev. Ib qho ntxiv, hom txheej txheej no tau pom nws daim ntawv thov hauv cov hauv paus ntsiab lus tiv thaiv dej. Qhov no yog cov ntaub ntawv xav tau, feem ntau cov kws tshaj lij pom cov yam ntxwv zoo xws li:
- siab tsis ntawm waterproofing;
- yooj yim ntawm kev teeb tsa ua haujlwm;
- qis tshwj xeeb lub ntiajteb txawj nqus;
- Kev Nyab Xeeb Ib puag ncig;
- tus nqi qis.
Txawm li cas los xij, RCP cov khoom siv vov tsev tsis muaj qhov tsis txaus ntawm nws tus kheej qhov tsis xws luag, txawm hais tias lawv siv tsis txwv qhov txwv ntawm cov khoom siv no hauv txhua txoj kev:
- lub sijhawm luv ntawm kev siv;
- tsis kam tua hluav taws;
- qhov kev pheej hmoo ntawm kev puas tsuaj ntawm cov khoom siv ua ntej yug thaum muaj kev cuam tshuam ncaj qha ultraviolet rays;
- qhov ua tau ntawm kev faib cov khoom vov tsev thaum txhim kho cov txheej txheem txheej ntau txheej;
- tsawg tsis ntawm elasticity.
Txawm hais tias tag nrho cov kev tsis txaus no, cov yam ntxwv ntawm RCP cov khoom siv hauv tsev ua tau raws li txhua qhov kev xav tau rau kev tiv thaiv dej thiab vov tsev. Tias yog vim li cas cov khoom siv yog nrov heev nrog cov tswv ntawm lub tsev sov lub caij ntuj sov thiab cov tsev nyob hauv tsev. Nws yog siv hauv kev tsim cov tsev thiab lwm yam kev tsim tawm.
Yuav ua li cas pawg?
Feem ntau ntawm cov xwm txheej, RCP cov khoom vov tsev tau tso los ntawm txoj kev txias ntawm bitumen mastic. Txhawm rau ua lub ru tsev ruaj ntseg tiv thaiv dej, koj yuav xav tau:
- txheej hauv qab RPP;
- vov tsev khoom RCP;
- bituminous primer;
- bituminous mastic;
- riam rau txiav daim ntaub.
Ua ntej pib ua haujlwm, nws yog qhov tsim nyog los npaj lub hauv paus. Nws yuav tsum tau ua kom huv thiab huv si, tsis pub lub qhov av los yog qhov av tawg. Ib qho tsis xws luag yuav tsum tau muab tshem tawm ua ntej nrog cov dej tsis haum los yog cov tshuaj cement.
Tsuas yog tom qab ntawd koj tuaj yeem pib tso cov khoom vov tsev.
Nws yog qhov yooj yim heev rau txheej cov khoom vov tsev. Ua ntej, mastic tau siv rau thaj tsam me me, thiab tom qab ntawd txheej txheej ntawm RCP cov khoom siv vov tsev tau maj mam nkag mus rau nws . Cov txheej yuav tsum tau kho kom nruj li sai tau thiab nias khov kho mus rau lub hauv paus. Txhawm rau ua kom tsis muaj dej, koj yuav xav tau yam tsawg 3-4 txheej, lawv tau tso nrog kev sib tshooj. Yog li, txhua txheej txheej tom ntej ntawm daim ntaub tau muab tso kom nws sib koom ua ke sib koom ua ke ntawm cov ntsiab lus dhau los ntawm 15-20 cm. Cov txheej txheej tiav yog qib nrog cov menyuam yaus.
Cov txheej txheem txheej txheem ntawm kev tso cov khoom vov tsev RCP nrog kev pab ntawm cov ntsia hlau thiab cov slats tsis tau dav . Hauv qhov no, kev tsim qauv yog tus yam ntxwv ua tau zoo qis, nws tuaj yeem xau thiab tsis muab kev tiv thaiv tsim nyog tiv thaiv qhov tsis zoo ib puag ncig. Ib qho ntxiv, thaum lub sijhawm txheej txheem teeb tsa, cov khoom siv vov tsev tuaj yeem tawg.
