Cov khoom dab tsi uas tsis muaj teeb meem yog qhov ua tau zoo, thiab dab tsi tsis yog heev? Peb muab los piv cov hom tseem ceeb.
Polyethylene
Polyethylene zaj duab xis ua ib txhais tau tias ntawm kev tiv thaiv vaj qoob loo ntawm tus mob khaub thuas yog paub txog lub tsev caij ntuj sov los ntawm Soviet lub sijhawm. Txawm hais tias qhov tseeb tias kev xaiv ntawm cov ntaub ntawv pom zoo rau cov tsev cog khoom thiab cov tsev ntsuab niaj hnub no yog dav, nws tseem tsis tau poob nws qhov tseeb.
Tus muaj peev xwm kis tau ntawm Underfloor polyethylene nyob rau hauv thaj tsam 80-90%, uas cuam tshuam rau kev loj hlob ntawm zaub qoob loo. Qee cov neeg ua teb xav txog qhov ntsuas no tsis siab txaus, tab sis nws tsis yog. Yooj yim pob tshab yog tsim nyog rau greenery, tab sis nws tuaj yeem cuam tshuam zaub: ntau dhau lub teeb yog tsis zoo rau cov hlua thiab kev txhim kho ntawm cov txiv hmab txiv ntoo. Cov nyhuv zoo sib xws ntawm lub hnub oversuply ntawm lub hnub yog manifested hauv kev sib raug zoo rau cucumbers, txiv lws suav thiab bakhchyev, cov txiv hmab txiv ntoo ntawm uas tej zaum yuav nyob ntawm qhov hnyav.
Ua tsaug rau zaj duab xis sab hauv lub tsev cog khoom, qib siab zoo ntawm cov av noo yog ib txwm txhawb nqa. Nyob rau tib lub sijhawm, qhov kub ntawm cov av ntawm lub txaj yog siab dua sab nraud. Yog li, qhov tshwj xeeb microclimate yog tsim, uas ua rau muaj kev ua kom nrawm nrawm ntawm cov nroj tsuag. Lawv tsis txaus ntshai te, cua hlob muaj zog, degrees lossis pos huab nrog overvoltage.
Lub ntsiab tseem ceeb ntawm polyethylene yog tsis zoo tsis kam rau kev puas tsuaj rau kev puas tsuaj: nws tuaj yeem siv nkaug, tawg lossis txiav. Qib ntawm cov coj tsis kam kuj tseem tawm ntau qhov xav tau. Cov khoom lag luam pheej yig tshaj plaws pab tsuas yog ib lub caij nyoog, raws li cov nag lossis daus thiab hnub rays sai sai, vim hais tias ntawm uas nws poob tau muaj peev xwm tiv taus khov.
Kev cais ntawm tes ntawm pawg polcarbonate
Vim nws cov qauv cellular, polycarbonate tau nce lub zog ntxiv thiab zoo-txuag hluav taws xob. Tsis zoo li cov yeeb yaj kiab pheej yig los ntawm polyethylene, nws yog resistant rau lub load ntawm qhov sib txawv, nws tsis puas los ntawm cua thiab lawg, tsis ntshai ntawm kev tawm tsam random. Lub pob tshab ntawm cov vaj huam sib luag yog 86%. Nyob rau tib lub sijhawm, lawv tsis poob lawv cov neeg tau txais kev pab cuam vim muaj cov txiaj ntsig ntawm Ultraviolet, vim tias txheej tiv thaiv tshwj xeeb yog thov rau lawv sab pem hauv ntej.
Cov khoom siv tuaj yeem siv tau ntawm txhua qhov kub hauv qhov ntau ntawm -40 txog + 1200C, uas ua rau nws yuav luag tsis tau txais kev tshem tawm. Tsis xav paub txog lub neej ntawm lub cellular polycarbonate yog tsawg kawg yog 15 xyoos.
Tsis muaj qhov tsis txaus ntseeg loj tshwj tsis yog siab dua (hauv kev sib piv nrog cov yeeb yaj kiab) tus nqi, muaj tsis muaj cellular yas. Qhov loj tshaj plaws yog xaiv lawv los xaiv thiab mounted.
Thaum xaiv, ua ntej ntawm txhua yam, nws yog ib qho tsim nyog yuav tsum tau coj mus rau hauv tus account tag nrho cheeb tsam ntawm lub tsev xog paj. Yog tias nws tsis loj heev (txog 30 m2), yuav dhau tuab yas yas rau txhua yam, hauv qhov no yuav tsum raug kaw rau cov panels nrog ib thickness ntawm 6-8 hli. Rau cov qauv tsim ntawm txog 20 M2, Polycarbonate yog qhov tsim nyog thinnner - 4-6 mm. Cov khoom ntawm 10 hli tuab thiab siab dua yog siv rau cov tsev loj, ntawm 40 m2.
Raws li twb tau hais, feem ntau cov panels muaj cov txheej txheem tiv thaiv los ntawm cov teeb meem tsis zoo ntawm lub hnub ci. Nyob rau tib lub sijhawm, qee cov tuam ntxhab txhawm rau txhawm rau txo lawv cov khoom lag luam tsis tiv thaiv nws los ntawm ultraviolet. Yog li ntawd, thaum yuav khoom, koj yuav tsum tau paub tseeb tias cov khoom nyiam cov khoom siv tsis ntshai lub hnub.
Zoo Polycarbonate yog txawv los ntawm kev dag:
- Ntawv tuab. Txheem pob tshab cellular cellular lub tsev ntsuab muaj ib qho tuab ntawm tsawg kawg 4 hli, thiab pheej yig, dag ntxias cov neeg yuav khoom thiab muab cov polycarbonate rau cov qauv.
- Lub thickness ntawm sab hauv partitions thiab sab nraud phab ntsa, thiab yog li ntawd, thiab qhov hnyav. Txheem nplooj ntoos rau ib tsev cog khoom 6 m yuav tsum hnyav 10 kg.
- Lub xub ntiag ntawm cov yeeb yaj kiab zoo.
Cov Tsis Muaj
Ntau zaus nyob rau hauv lub vaj koj tuaj yeem pom cov yeeb yaj kiab los ntawm Propylene. Sab nraud, nws zoo li ntau-txheej gauze los ntawm intertwined translucent xov. Hom nto moo tshaj plaws - Agril, Loutrasil thiab Spunbond. Lawv tsim nyob rau txawv teb chaws, tab sis nws tsis tas yuav tsum tau taug qab cov chaw tsim khoom, tab sis ntawm cov tuab ntawm cov khoom thiab nws lub hom phiaj.
Yog li, cov dawb thiab nyias "tsis muaj" qhov ntom ntawm 17 g / m2 tiv thaiv cov nroj tsuag los ntawm kab tsuag thiab fros me me (txog li - 20 ° C). Siv nws feem ntau yog tsis muaj lub hauv paus txhav. Tab sis probylene yog cov muaj feem xyuam (30-60 g / m2) yog siv twb ua ke nrog cov ntaub ntawv ntawm frosts rau -60c. Nyob rau tib lub sijhawm, cov tuab (60 g / m2) ntawm cov dub hniav tiv thaiv cov qoob loo los ntawm kev sib cais ntawm cov nroj.
Cov ntaub ntawv tsis yog qhov txawv los ntawm qhov tseeb tias huab cua, dej thiab tshav ntuj ci tau dhau mus hauv cov tshuaj noj. Piv txwv li, nyob rau hauv lub caij ntuj sov tshav kub, dawb polypropylene txuag tau tawm overheating, thiab dub (nyob rau lub caij nplooj ntoo hlav) tsis muab rau lawv rau kev mob siab.
Hmoov tsis zoo, propylene fiber ntau, ntxiv rau polyethylene, tsis muaj lub zog txaus, hnav tawm thiab maj. Feem ntau cov feem ntau nws yog siv los ua cov mulch, tsawg dua feem ntau - raws li lub vaj tse tag nrho ntawm txoj kab sib zog.
Lub khob
Iav Greenhouses yog ib txwm siv nyob rau hauv tag nrho cov cheeb tsam, tsis hais thaj chaw thiab huab cua yam ntxwv. Thiab qhov no yog to taub: iav raws li cov khoom siv los tiv thaiv cov nroj tsuag los ntawm lwm yam sab nraud muaj tag nrho cov teeb tsa ntawm qhov zoo. Ntawm lawv yog lub teeb zoo heev lub teeb transpact cov khoom, thiab zoo thermal rwb thaiv tsev, thiab muaj peev xwm tiv thaiv cov khoom siv daus tseem ceeb. Ib qho ntxiv, cov iav sash uas tau dhau los ua ib txwm tuaj yeem hloov tau sai.
Ntawm chav kawm, muaj txoj hauv kev pheej yig los tsim lub tsev cog khoom. Txawm li cas los xij, yog lub Windows qub nyob hauv lub tsev teb, lub qhov rais qub yog hmoov av, ces lawv tsis pom kev siv zoo dua. Tshwj xeeb tshaj yog txij li kev siv ntawm lawv rau kev tsim kho yog txoj hauv kev zoo heev kom txuag tau.
Ncej yog qhov yooj yim los sau los ntawm tsob ntoo. Txhawm rau ua qhov no, koj yuav tsis tas yuav tau txais cov khoom tshwj xeeb, zoo li cov ntoo yog ua tiav yooj yim heev. Raws li, yuav tsis muaj teeb meem nrog kev sib txuas ntawm cov ntsiab. Yuav tsum muaj tsis muaj cov ntaub ntawv tsis muaj, vim tias muaj ib txwm muaj qee cov neeg tuaj yeem pab tau hauv kev ua haujlwm.
Tsis txhob poob lub qhov muag qub thav ntawv los ntawm cov nyiaj. Lawv yuav tseem ua tau kev txuag nyiaj txiag hauv tsev neeg thiab pab ua lub cev rau lub tsev cog khoom. Nws tseem tsim nyog sau qhov tseeb tias qub thav ntawv pom sab nraud thaum hloov cov qhov rai tshiab thiab koj tuaj yeem tuaj tos lawv kom dawb.
Yog tias xav tau qauv ruaj khov yog qhov xav tau, nws ua rau kev nkag siab kom npaj txhij-ua iav tsev cog khoom nrog cov duab puab txhuas.
Lus ntuas
- Hauv kev tsim kho ntawm cov tsev ntsuab, qhov xaus ntawm daim ntawv polycarbonate yuav tsum tau tiv thaiv los ntawm kev nkag mus ntawm noo noo nrog cov plugs tshwj xeeb.
- Nrog kub ceev poob, yas yuav nqaim lossis nthuav dav. Yog tias nyob rau hauv cov txheej txheem ntawm kev teeb tsa tsis coj mus rau hauv tus account qhov xwm txheej no, cov khoom yuav tawg thiab tsum yuav tsum tau muab ntim.
Andrei Kartsev, Dachnik:
Siv lub teeb pom kev zoo rau tsev cog khoom. Txhua tus paub tias ib qho tseem ceeb Backlight yog qhov tseem ceeb hauv tsev cog khoom, tab sis kev siv hluav taws xob rau kev noj haus liab tsis tau coj mus rau qhov kev tshaj tawm ntawm qhov kev txais tos. Hauv av cog qoob loo, cov nyom no tau tshem tawm los ntawm kev hloov cov khoom siv hauv qab (Phosphic) muaj peev xwm hloov khoom ntxiv rau hauv lub teeb liab uas muaj txiaj ntsig txuam nrog emerson nyhuv.
