Ngati mukufuna kulandira zokolola zambiri popanda kugwiritsa ntchito feteleza zamchere, popanda kuthirira madzi, popanda kuika mbewu dzuwa lotentha kapena kuzizizira panthawi ya chisanu, mukufunikira spunbond. Kodi nkhaniyi - spunbond ndi chiyani? Tiyeni tione m'nkhaniyi.
Spunbond oswoven zakuthupi
Spanbond yakhala ikufalikira pakati pa alimi wamaluwa ndi amalima a galimoto chifukwa cha katundu wawo wosakayika. Idawonekera pamsika wa Russia ndipo posachedwa sanadziŵike chifukwa cha kusakhulupirira kwa anthu okhala m'nyengo ya chilimwe. Ndipo mwachabe! Ubwino wogwiritsa ntchito nkhaniyi sizingatheke kwambiri.
Kuphimba zipangizo zaulimi zimakhala ndi zizindikiro zotsatirazi:
- kuwala, wamphamvu, osati nsalu;
- wokonda zachilengedwe;
- sikumabwereketsa kuzinthu;
- imatulutsa chinyezi ndi mpweya;
- amateteza zomera motsutsana ndi kusintha kwa kutentha.
Ntchito ya spunbond
Zinthuzo, zomwe zimatchedwa agrovoloknom, zimagwiritsidwa ntchito kubisa mabedi omwe mbande zoyambirira zimabzalidwa, zomwe zimayenera kutetezedwa kuchisanu cha chisanu. Komanso, mfundozi zimateteza zomera m'chilimwe padzuwa.
Musawope kuti spunbond idzateteza kukula ndi kukula kwa zomera. Nsaluyi ili kwenikweni kuwala, kotero izo zizingokwera ndi ziphuphu.
Mbali yina yogwiritsira ntchito mfundoyi ndi wowonjezera kutentha . Amatsitsa filimu ndi galasi. Mosiyana ndi zipangizozi, spunbond imadutsa madzi amvula, mpweya watsopano, popanda kuwonjezera kutentha kwakukulu.
Mbali yina yogwiritsira ntchito zowonongeka zapunbond ndi nthaka mulching . Kuti muchite izi, gwiritsani ntchito spunbond yakuda. Iye aikidwa pa malo oyeretsedwa. Zomwe zimapangitsa kuti kuwonjezeka kwa nthaka kutentha komanso kutayika kwa mbewu zamsongole.
Kuonjezerapo, spunbond imapangira mitengo ndi zitsamba kuti zisawononge imfa ndi kuwonongeka pa chisanu.
Kodi spunbond imagwira ntchito bwanji?
M'dzinja, chophimba chimagwiritsidwa ntchito monga chitetezo ku nyengo zovuta, monga mphepo, matalala, mkuntho. Momwe zinthu zimakhalira masana, spunbond imatsimikizira kuti ili ndi mphamvu ndipo imathandiza kuti pakhale zokolola zambiri. Kumapeto kwa nyengo kumapeto kwachilengedwe chimasintha chilengedwe chipale chofewa, kuteteza zomera kuledzera ndi kuzizira.
M'nyengo yozizira yotchedwa spunbond imateteza chisanu, kusunga chisanu. Komabe, kumapeto kwa nyengo, n'zotheka kuyamba kumera kale kwambiri. Kutetezeka kumateteza chisanu cha usiku, komanso tizilombo ndi tizirombo tina.
Kugwiritsiridwa ntchito kwa spunbond m'chilimwe kumachepetsa kutaya kwa chinyezi, kumateteza mphepo yamphamvu, kutentha kwambiri, zotsatira zowonongeka za kuwala kwa dzuwa, pamene mpweya wabwino ndi ultraviolet.
Kodi spunbond yapangidwa motani?
Chophimba chophimba chimapangidwa ndi polypropylene spun-bonded. Zimasungunuka, ndipo zotsalira zopanda malire zimachotsedwa ndipo zimayikidwa pamtengowo pogwiritsira ntchito zipangizo zamakono. Zipangizozi zimagwiritsidwa ntchito mosakanikirana mothandizidwa ndi kutentha kwakukulu.
Zotsatira zake, zimapezeka mwamphamvu kwambiri, zomwe sizingatheke ndi manja opanda manja.
Pogwiritsa ntchito makinawa, zowonjezera zowonjezera zowonjezereka zimaphatikizidwa ku spunbond, zomwe zimapangitsa kuti chiwonongekocho chiziwonongedwa ndi dzuwa. Zotsatira zake, zidazo zingagwiritsidwe ntchito zaka zisanu kapena kuposerapo. Firimuyi sitingadzitamande ndi moyo wautali wotero. Izi ndi zina zonse zabwino zikufotokoza kukula kwa nsalu zamakono pakati pa wamaluwa wamakono.
