Yambitsani nsalu ya PP yosungunuka

Nsalu yosungunuka (nsalu yosungunuka yosalala) ndi chinthu chopangidwa ndi nsalu yosungunuka kwambiri ya PP (polypropylene) yopangidwa ndi nsalu yopanda nsalu. Ndizofunikira pachimake. Kukula kwa ulusi wa spinneret kumatha kufikira 0.001 mpaka 0.005 mm. Pali ma void ambiri, mawonekedwe osalala, makwinya abwino, ndi mawonekedwe apadera a capillary. Ulusi wa Ultrafine umakulitsa kuchuluka ndi ulusi wazipangizo zonse, kotero kuti nsalu yosungunuka imakhala ndi zotsekemera, zotchinga, zotchingira kutentha komanso kuyamwa mafuta. . Kugwiritsa ntchito kwake kwakukulu ndi kusefera kwa mpweya, kusefera kwamadzimadzi, kusungunuka kwa ukhondo wa chakudya, mafakitale osungira mafumbi, etc. Kuphatikiza apo, itha kugwiritsidwanso ntchito ngati zinthu zachipatala ndi zaukhondo, zopukutira mwatsatanetsatane wamafuta, zida zotchingira mafuta, mafuta- zipangizo zopangira, olekanitsa mabatire, ndi nsalu zachikopa zosanzira. ndi zina zambiri. Chiyambireni mliri watsopano wa korona wapadziko lonse lapansi, State Assets Supervision and Administration Commission ya State Council yapempha makampani oyenera kuti apititse patsogolo ntchito yomanga mizere yopanga, kuti apange kupanga mwachangu, ndikukulitsa kupezeka kwa meltblown nonwovens kumsika kuti ateteze kapewedwe ka mliriwu.

Madera ogwiritsa ntchito nsalu zosaluka zosungunuka:
1. Kugwiritsa ntchito kuyeretsa kwa mpweya: kumagwiritsidwa ntchito poyeretsa mpweya, ngati chopangira mpweya wabwino kwambiri, ndikugwiritsanso ntchito kusefera kwamphamvu komanso kwapakatikati kotulutsa mpweya wochulukirapo. Ili ndi maubwino otsika otsika, mphamvu yayikulu, asidi wabwino komanso kukana kwa alkali, kukana dzimbiri, magwiridwe antchito, moyo wautali, ndi mtengo wotsika.
2. Application in the medical and health field: The dust-proof port made of melt-blown cloth has low breathing resistance, is not stuffy, and has a dust-proof efficiency of up to 99%. It is widely used in hospitals, food processing, mines, etc. that require dust and bacteria prevention In the workplace, the anti-inflammatory and analgesic film made by the product after special treatment has good air permeability, no toxic side effects, and easy to use. SMS products compounded with spunbond fabrics are widely used in the production of surgical clothing and other sanitary products. <br>
3. Zosefera zamadzimadzi ndi zakulera za batri: Chovala chosungunuka cha polypropylene chimagwiritsidwa ntchito kusefa zakumwa zamchere ndi zamchere, mafuta, ndi zina zotero. Zili ndi magwiridwe antchito abwino, zimawonedwa ngati cholembera chabwino ndi makina amabatire kunyumba ndi kunja, ndipo lakhala likugwiritsidwa ntchito kwambiri, Sikuti limangochepetsa mtengo wa batri, limachepetsa njirayi, ndipo limachepetsa kwambiri kulemera kwake ndi kuchuluka kwa batri.
4. Zida zopangira mafuta komanso zopukutira mafakitale: zida zosiyanasiyana zopangira mafuta zopangidwa ndi polypropylene nsalu yosungunuka, yomwe imatha kuyamwa mafuta mpaka nthawi ya 14-15 kulemera kwake, imagwiritsidwa ntchito kwambiri pachitetezo cha chilengedwe ndi ntchito zopatukana ndi madzi. Kuphatikiza apo, amagwiritsidwa ntchito popanga mafakitale. , Itha kugwiritsidwa ntchito ngati choyera cha mafuta ndi fumbi. Mapulogalamuwa amasewera kwathunthu ku polypropylene palokha komanso kutsatsa kwa ulusi wa ultrafine wopangidwa ndi meltblown.
5. Zipangizo zotchingira kutentha: Makulidwe amtundu wa ulusi wosungunuka amakhala pakati pa 0,5-5μm, ndipo amapangidwa mwachindunji kukhala nsalu zosaluka mwa kuyika mwachisawawa. Chifukwa chake, malo omwe ali ndi ulusi wosungunuka ndi akulu ndipo porosity ndiyokwera. Mpweya wambiri umasungidwa momwemo. , Zitha kuteteza kutentha, ndi zosefera zabwino kwambiri komanso zotchinjiriza. Amagwiritsidwa ntchito kwambiri popanga zovala ndi zida zingapo zotenthetsera. Monga jekete zachikopa, malaya ski, zovala zosazizira, nsalu za thonje, ndi zina zambiri, zimakhala ndi kulemera, kutentha, kusayamwa chinyezi, kuloleza kwa mpweya, komanso palibe cinoni.
