Momwe mungakwaniritsire N95+kusungunukansalu yosalukidwa, akatswiri athu opanga zinthu amvetsetsa.
Pali zinthu zambiri zomwe zimakhudza mtundu wa nsalu zopanda ulusi zomwe zimasungunuka
Kuyambira zipangizo zopangira mpaka zida
Njira iliyonse ndi yofunika kwambiri
Ngakhale pali zinthu zomwe zili payekhapayekha
Ubwino wa chinthu chomaliza ungasiyane kwambiri
Pambuyo pa kafukufuku wozama wa Razer ndi mayeso obwerezabwereza
Sungunulani nsalu zosalukidwa mpaka N95+
Madera asanu ndi atatu otsatirawa ayenera kulamulidwa mosamala
Tsopano ndi aliyense mosamala
zinthu zosungunuka
1. Ili ndi fungo lochepa, phulusa lochepa, kuchuluka kwake ndi kugawa kwake kulemera kochepa.
2. Kuchuluka kwa ndalama.
3. Ulusi wabwino kwambiri, ukhoza kupangitsa kuti ulusi ukhale wokulirapo, ndipo waya wake ndi wochepa.
4. Silika wokhazikika, zinthu zotayira, kusinthasintha kwa spinnability kuli bwino.
5. Yosavuta kugwiritsa ntchito, magwiridwe antchito okhazikika.
6. Itha kugwiritsidwa ntchito popanga zinthu zosefera, thonje loyamwa mafuta, zinthu zothandizira zovala, diaphragm ya batri ndi ntchito zina zosungunula.
momwe mungapangire nsalu yosungunuka
1. Ulusi uyenera kukhala wabwino, kuchuluka kwa zinthu zopangira ndi kukula kwa mbale ya spinneret zikugwirizana, ndipo njira ya spinneret imakonzedwa bwino, kotero kuti ulusiwo ufike pa 0.3um.
2. kufananiza zida zabwino za electret ndikusankha electret masterbatch yabwino. Tinthu tabwino ta electret master tiyenera kukhala ndi mphamvu yosungira mphamvu ndikupanga magetsi kosatha.
3. Nthawi yogwira ntchito ya chigoba mu electret imadalira kwambiri kuchuluka kwa electret masterbatch. Electret masterbatch ndi yofanana ndi batri, kuwonjezera chiŵerengero kudzatsimikizira moyo wake ndi mphamvu yake yoyamwa.
4. Umitsani nsalu yosungunuka ndipo muisunge. Siingakhudze chinyezi cha mpweya wakunja. Kuyika vacuum ndikwabwino kwambiri. Chinyezi mumlengalenga ndi mphamvu mu nsalu yosungunuka zidzasanduka ma ayoni oipa, ndipo kutayika kwa mphamvu kudzakhudza momwe zinthu zimasefedwera.
3. Zifukwa za nsalu yosalimba yosungunuka
1. Zida zosinthira ndi zosungunuka
2.zipangizo zamagetsi zamagetsi
3.zinthu zamakono zamagetsi zamagetsi zamagetsi nthawi yayitali
4. kupopera kwa melting kapena kusungunula kwambiri chala chala
5. katswiri komanso wodziwa bwino kusintha makina
6. Kuyang'anira malo opangira zinthu zosungunuka
momwe mungasankhire zinthu zosungunuka
1. kusungunuka: polypropylene powonjezera peroxides kutentha kuwonongeka kapena metallocene hydrogen kusintha njira, polypropylene kusungunuka kuti ifike pamlingo woyenera wapamwamba, kungapangitse nanoscale fiber.
2. Malo osungunuka a tinthu tating'onoting'ono ayenera kuchepetsedwa kufika pakati pa 150-170°C.
3. Pambuyo powonjezera tinthu ta electret master, nsalu yosungunuka idzapanga mphamvu ya electrostatic adsorption kudzera mu chipangizo cha electret kuti iteteze kachilomboka.
4. Pambuyo pa kusintha kwa tinthu ta polypropylene, ulusi womwe umatulutsidwa ndi makina osungunuka ndi nsalu pa kutentha kwakukulu komanso kuthamanga kwambiri umakhala wabwino komanso wautali.
5. Ulusi wamadzimadzi womwe umatuluka mu nozzle yosungunuka yokha ndi wofewa, wolimba komanso wolimba.
6.kuyeretsa thupi ndi kutentha kwambiri.
kusankha kwa batch ya electret master
1. Nthawi yodzaza ndi electrostatic, kaya ikhoza kuyikidwa kwa nthawi yayitali mpaka chaka chimodzi kapena kuposerapo.
2. electret masterbatch simatseka dzenje losungunuka ndi meltblown, kuyika ndalama pa nsalu yosungunuka ndi meltblown, momwe mungapangire kuti positive charge ikhale nthawi yayitali pa nsalu yosungunuka ndi meltblown, ikhoza kutero
Pambuyo pa theka la chaka kapena chaka chimodzi palibe kutayika kwa ndalama, khalani mayeso a electret master batch ndi electret process key index.
3. Kuzungulira kwa block yayitali, electret yayitali, PFE imaposa 95.
Chithandizo cha njira ya Electret
1. Njira yodziwika kwambiri ndiyo njira yolipirira korona pochiza nsalu yosungunuka pogwiritsa ntchito magetsi. Voltage yolipirira, nthawi yolipirira, mtunda wolipirira ndi chinyezi cha chilengedwe zonse zimakhudza momwe chithandizo cha magetsi chimakhudzira.
Voliyumu yochaja imakhala ndi zotsatira zoonekeratu pa mphamvu ya electret, mtunda wochaja umakhala ndi zotsatira zapakati, ndipo nthawi yochaja imakhala ndi zotsatira zochepa. Samalani mukasintha makina.
2. Chinyezi cha mlengalenga chimakhudza kupanga ndi kutayika kwa magetsi osasinthasintha. Kampani yopangidwa ndi nsalu yosungunuka iyenera kuyang'anira kutentha ndi chinyezi mu workshop nthawi zonse. Wonjezerani zida zoyenera kuti kutentha ndi chinyezi mu workshop zisunge mkati mwa mtunda winawake.
zinthu zosungunuka
1. Ngati polypropylene yosungunuka ikakhala kutentha kwambiri komanso kupanikizika kwa nthawi yayitali, zimakhala zosavuta kuipitsa ndi kuipitsa.
2. Posintha kutentha kwa makina, choyamba, ndikofunikira kudziwa ngati kutentha kwenikweni kwa mbiya ndi nkhungu pa makina osungunuka zikugwirizana ndi kutentha komwe kwakhazikitsidwa. Nthawi zambiri kutentha pang'ono kwa zida zosungunuka ndi kutentha kwenikweni kumakhala kosiyana kwambiri.
3. Kusungunuka kumatanthauza polypropylene ya 1500, ngati kutentha kwayikidwa pa 270℃, kukwera pang'ono.
Kusankha zida zopukutira zosungunula
1. Kapangidwe kake kayenera kukhala kokwanira: chotulutsira zinthu → chosinthira pazenera (fyuluta)→ pampu yoyezera → mutu wofewa → mbale yogawa (mpweya wotentha wothandiza) → spinneret → chipangizo cha mesh kuti chipange nsalu yosungunuka.
2. liwiro la extruder, magawo a pampu yoyezera, ubwino ndi zolakwika za mutu wa die, magawo a kutentha ndi liwiro la kayendedwe ka mpweya wotentha, Ngodya ya mutu wa die, Ngodya ya tsamba la mpweya, mtunda wolandirira zinthu zosungunuka, magawo a kulowetsedwa pansi pa chipangizo chopangira ukonde ndi zina zotero zimatsimikiza pamodzi mtundu wa nsalu yopopera yosungunuka.
Zomwe zili pamwambapa ndi njira yopangira nsalu yopanda ulusi yosungunuka. Ndife akatswiri opanga nsalu yopanda ulusi, Huizhou Jinhaocheng Non-woven Co., Ltd. Ndikukhulupirira kuti nkhaniyi yakuthandizani.
