Kugwiritsa ntchito nsalu zosiyanasiyana zolemera za spunbond nonwoven muulimi

Nsalu zopanda nsalu za Spunbond zakhala zikugwiritsidwa ntchito kwambiri ngati filimuzophimbamu ulimi. Kuthekera kwa madzi ndi mpweya kudutsa mwaufulu kumapangitsa kuti ikhale yotchuka kwambiri paulimi ngati chophimba cha greenhouses, greenhouses opepuka, komanso kuteteza mbande nthawi iliyonse, kulikonse.

Tiyeni tiwone momwe nsalu zaulimi za spunbond zosawoloka zimapangidwira mosiyanasiyana. Musaiwale kuti pazosankha zonse zogwiritsira ntchito, mbali yosalala ya nsalu iyenera kuyang'ana kunja, pamene mbali ya suede iyenera kuyang'anizana ndi zomera. Kenako, pamasiku amvula, chinyezi chochulukirapo chidzatayika, ndipo fuzz yamkati imasunga chinyezi, ndikupanga nyengo yabwino kwa zomera.

The thinnest ndi wopepuka. Mu horticulture, amagwiritsidwa ntchito kuphimba mbande ndi mbande panthaka kapena zomera. Pansi pake pamatentha kwambiri, ndipo masamba osasweka omwe amawonekera momasuka amakweza kangaude wotchingidwa ndi chovala chowala. Pofuna kupewa kuti chinsalucho chisawombedwe ndi mphepo, chimayenera kufinyidwa ndi miyala kapena matabwa kapena kumangidwa ndi anangula okhudzana ndi ulimi.

Mukathirira kapena kugwiritsa ntchito feteleza osungunuka, chophimbacho sichingachotsedwe - madzi otuluka sangachepetse konse. Nsalu iyi ya spunbond yosalukidwa imatha kupirira chisanu mpaka -3 ° C, kutumiza kuwala, mpweya, ndi chinyezi, kupanga microclimate yabwino kwa zomera, kuchepetsa kusintha kwa kutentha, ndi kuchepetsa kutuluka kwa madzi m'nthaka. Komanso, izo mwangwiro kuteteza tizirombo. Itha kuchotsedwa panthawi yokolola. Kwa mbewu zomwe zili ndi mungu pa nthawi ya maluwa, chophimbacho chiyenera kuchotsedwa. Momwemonso, nsalu zaulimi zamtunduwu zitha kugwiritsidwa ntchito m'malo obiriwira osatenthedwa nthawi yachisanu nthawi yachisanu kutenthetsa mabedi.

Choncho, chinthu cholimba kwambiri sichiyenera kukhala ndi mabedi ogona okha, komanso kumanga nyumba zazing'ono zobiriwira. Chitetezo chodalirika cha zomera ku kuzizira, chisanu mpaka -5 ° C, komanso kuwonongeka kwa tizilombo, mbalame ndi matalala. Mogwira kuteteza kutentha kwambiri ndi kutenthedwa, kuchepetsa evaporation madzi m'nthaka, ndi kulimbikitsa mulingo woyenera kwambiri chinyezi okhutira. Mbewu zazikulu monga zitsamba ndi mbande za mitengo yazipatso zimathanso kutetezedwa ndi izi.

Zofewa ndinsalu yolimba ya spunbond yopanda nsalu. Zosavuta kuphimba madera akuluakulu, monga udzu ndikutsanzira chivundikiro cha matalala, makamaka m'dzinja ndi kumayambiriro kwa masika. Imatha kufalitsa kuwala ndi madzi, kuteteza mbande, zitsamba ndi mitengo ku chisanu chanthawi yochepa chotsika mpaka -7 ° C.

Kuchulukana kwa chinsaluchi kumagwiritsidwa ntchito nthawi zambiri ngati zokutira pamafelemu ang'onoang'ono opindika kapena ma greenhouses. Momwemo, gwiritsani ntchito mapaipi osalala kuti mupange ma arcs ndikuwateteza ndi zozungulira zozungulira kuchokera ku wowonjezera kutentha, kuti zikhale zosavuta kugawa. Chifukwa cha mawonekedwe a nsalu zaulimi, greenhouse microclimate imapangidwa mkati, yomwe ili yoyenera kwambiri pakupanga photosynthesis. Makoma a wowonjezera kutentha kumeneku sadzapanga madzi oundana, ndipo zomera 'sizidzaphika' mmenemo. Kuonjezera apo, makulidwe awa a nsalu zopanda nsalu amatha kukana matalala ndi mvula yambiri.

Ichi ndi nsalu yokhuthala komanso yolimba kwambiri yopanda nsalu yoyera. Ntchito yake yayikulu ndi greenhouses. Maonekedwe a geometric wa wowonjezera kutentha amapereka mikhalidwe ya kugubuduza kwa chipale chofewa, chomwe sichingachotsedwe m'nyengo yozizira, ndipo chimatha kupirira nyengo 3-6, zomwe zimagwirizana ndi zitsanzo zapamwamba kwambiri zokutira wowonjezera kutentha. Komabe, kuphatikiza nsalu zaulimi zopanda nsalu ndi filimu zimatha kupeza zotsatira zabwino.

Chifukwa cha kukana kwachisanu kwa filimuyo mu kasupe, ndi bwino kupereka chithunzithunzi chofulumira mu kapangidwe ka wowonjezera kutentha. Mungagwiritse ntchito kuti muyike mwamsanga kapena kuchotsa filimuyo ndi zokutira zaulimi pazosakaniza zilizonse kuchokera kumanja. Chifukwa chake, zikhalidwe zilizonse zitha kupangidwa - kuchokera pachitetezo chambiri chotenthetsera mu zigawo ziwiri kupita ku dongosolo lotseguka la wowonjezera kutentha.

Pazaulimi, m'lifupi mwansalu zosalukidwa pamsika nthawi zambiri zimakhala zosakwana 3.2 metres. Chifukwa cha dera lalikulu laulimi, nthawi zambiri pamakhala vuto lakusakwanira m'lifupi mwa nsalu zopanda nsalu panthawi yophimba. Chifukwa chake, kampani yathu yasanthula ndikufufuza pankhaniyi, yapanga luso laukadaulo, ndikupanga makina osalukitsidwa ndi makina ophatikizika kwambiri. Nsalu yopanda nsalu imatha kupangidwa m'mphepete mwake, ndipo m'lifupi mwa nsalu yopanda nsalu imatha kufika mamita makumi. Mwachitsanzo, nsalu yopanda nsalu ya mamita 3.2 imatha kugawidwa m'magulu asanu kuti ipeze nsalu yopanda nsalu ya mamita 16. Ndi zigawo khumi za splicing, zimatha kufika mamita 32 ... Choncho, pogwiritsa ntchito nsalu zopanda nsalu m'mphepete mwa splicing, vuto la kusakwanira m'lifupi likhoza kuthetsedwa.

Mipikisano wosanjikiza sanali nsalu nsalum'mphepete splicing, anafutukuka sanali nsalu nsalu m'lifupi akhoza kufika makumi mamita, kopitilira muyeso lonse sanali nsalu nsalu kujowina makina!
