Lero, kusamalira munda wa ndiwo zamasamba ndikukula zipatso n'zosavuta kuposa zaka zambiri zapitazo. Izi zimalimbikitsidwa ndi chitukuko cha sayansi, nthambi zina zomwe zimakhudza ulimi. Zida zamakono, njira ndi zipangizo zimaperekedwa. Posachedwapa, m'madera ambiri spunbond ikugwiritsidwa ntchito kwambiri, yomwe, malinga ndi ogulitsa, imawalola kuti azikula zokolola zambiri ndi ndalama zochepa zomwe amagwira ntchito. Kodi ndi choncho? Tiyeni tiwone chomwe chiri - spunbond ndi kuganizira malo omwe akugwiritsira ntchito.
Spunbond - makhalidwe ndi ntchito
Spunbond ndi chinthu chosagwiritsidwa ntchito, sayansi yamakono imachepetsedwa pofuna kutentha mankhwala a polima (mwachitsanzo, polyamide, polypropylene) pozembera. Pachilumbachi, polima amayamba kukhala woonda kwambiri (filaments), omwe, atatulutsa, amalowetsamo muzenera umodzi pamtundu wozungulira. Chotsatira ndicho chingwe chokhala ndi mawonekedwe osiyana ndi osakanikirana mosiyanasiyana. Amasiyana ndi 15 mpaka 150 g / m & sup2. Spanbond ili ndi ubwino wambiri, monga:
- Kutsegula, chifukwa chomwe ngakhale minda ikhoza kuphimbidwa popanda mantha a kuwonongeka;
- Kulumikizana kwa chilengedwe, popeza nkhaniyo siimachotsa mvula m'mlengalenga ngakhale pamene ikuwotcha;
- mpweya ndi madzi okwanira, chifukwa chiyani pansi pa chinsalu chimapanga microclimate yabwino, koma samakhala ndi bowa ndi matenda;
- mphamvu, zomwe zimapitirirabe pansi pa zovuta zachilengedwe;
- deshiviznoy.
Ubwino wotere wa spunbond unapangitsa nkhaniyi kukhala yotchuka kwambiri m'madera ambiri.
Ntchito ya Spanbond
Masiku ano ntchito zosiyanasiyana zomwe amagwiritsira ntchito spunbond ndizosiyana kwambiri. Ngati tikulankhula za mankhwala ndi mautumiki, zipangizozi zimagwiritsidwa ntchito monga zovala zowonongeka komanso zotetezedwa, komanso zovala zowonongeka zomwe zimateteza ku fumbi ndi dothi. Komanso, mu mndandanda wa zopangidwa ndi spunbond, mungathe kutchula zinthu zaukhondo, mwachitsanzo, mapepala, mapepala, mapepala.
Kuonjezera apo, spunbond imagwiritsidwa ntchito kwambiri pamakina opanga ngati nsalu yophimba povala nsapato, nsapato, zipangizo zofewa, zikwama zamabedi ndi masutikesi, ndi zina zotero.
Mudzadabwa, koma zinthu zopanda ntchito zowonongeka zimagwiritsidwa ntchito pomanga monga zinthu zabwino zopewa madzi.
Spanbond mu gawo laulimi
Mwinanso omwe amagwiritsira ntchito kwambiri spunbond ndi eni omwe akulima mbewu zosiyanasiyana zaulimi. Ndipo chifukwa cha izi pali zifukwa zonse. Kwenikweni, zinthu zopanda nsalu zimagwiritsidwa ntchito ngati chophimba chophimba, chomwe chimapereka bwino kwambiri dzuwa, kutentha kapena kutentha, ndi chinyezi.
Kugwiritsiridwa ntchito kwa spunbond mu dacha kapena minda kumayesedwa ndi kuthekera kwa spunbond kuti apange wapadera, microclimate yabwino kwa zomera. Kumayambiriro kwa kasupe kapena m'dzinja, chingwechi chidzapulumutsa kukwera kwanu kwa chisanu. Ngati pali mvula yambiri, kuteteza zomera kuchokera ku chinyezi komanso matenda omwe angathenso kuwathandiza amadzaza ndi zowonjezera. Pewani kutentha kwa dzuwa kachiwiri kungakhale nsalu yopanda nsalu. Pankhaniyi, gwiritsani ntchito spunbond yokha.
Kuwonjezera apo, spunbond ndi njira yabwino kwambiri yowonjezera nthaka. Pachifukwa ichi, mpukutu wokhala ndi masentimita 70-80 g / m2 sup2 ndi mtundu wakuda, wakuda, umapezeka. Chovala chimaphimba bedi la munda, mabowo odula ndi mtanda kwa zomera zomwe zimalima. Chotsatira chake, mutatha kuthirira, chinyezi chimakhala chosatha m'nthaka, sichimasanduka, ndipo namsongole samakula chifukwa dzuŵa silingathe kulowa mkati. Kuonjezerapo, sponbond ikulimbikitsidwa kuphimba tchire ndi nyengo zosatha m'nyengo yozizira.
