Mu ndondomeko yopangirachosaluka chosungunuka, chifukwa cha kutentha, kuthamanga kwa mpweya, nkhungu, liwiro ndi zina mwa chiŵerengerocho, kotero kufunikira koyendetsa nthawi zonse ndikukonza zolakwika, kuti chinthucho chipeze zotsatira zabwino kwambiri. Izi ndi zomwe zafotokozedwa mwachidule mu njira yeniyeni yopangira kuti muwerenge:
Choyamba: Njira yosinthira makina
1. Pangani nsalu kukhala yofewa kutentha kwambiri ndi mphepo;
2. Pang'onopang'ono chepetsani kutentha kwa mutu wa die ndi kutentha kwa mpweya wotentha mpaka nsaluyo itawoneka yolimba pang'ono;
3. Lembani kutentha kwa mutu wa die ndi kutentha kwa screw panthawiyi;
4. Sinthani mphamvu ya mphepo, kuchuluka kwa madzi otuluka ndi mtunda wokwanira kuti nsaluyo ikhale yofewa kwambiri;
5. Sinthani liwiro lozungulira kuti mukwaniritse kugwira bwino ntchito;
6, poyimirira-mtengo malinga ndi liwiro la gululi, nthawi zambiri amawonjezerapo mipiringidzo iwiri yoyimirira-mtengo, voteji yokhazikika mu 40KV-60kV, mtunda wa mipiringidzo yoyimirira-mtengo ndi 5-7 cm pamwamba pa nsalu, pang'onopang'ono kuwonjezera magetsi okhazikika, mungasankhe kuwonjezera zabwino, mungasankhe kuwonjezera zoipa, mutha kudziwa mayeso.
Chachiwiri: Sinthani makonda oyambira
1. Kutentha kwa sikuru: seti 190 ° C, 230 ° C, 230 ° C..., madigiri 230, madigiri 270 (zinthu zosungunuka 1500 sizipitirira madigiri 270, zitha kukhala madigiri 260);
2, kutentha kwa die: madigiri 252, madigiri 252..., madigiri 252 (nthawi zambiri madigiri 240 -255);
3. Chosinthira pazenera mwachangu, pampu yoyezera, fyuluta ya mutu wa die: madigiri 240;
4. Kutentha kwa mphika wotenthetsera: madigiri 300, kutentha kwa mpweya wotentha: madigiri 240;
5, kuthamanga kwa mphepo: 0.2-0.5mpa (zinthu zonse za PP kutentha kochepa, kuthamanga kwa mphepo kungasankhidwe pang'ono, zinthu zapakati kutentha, kutentha kwa mphepo kungakhale kokulirapo pang'ono);
6. Mtunda wa ukonde: 15-19 cm;
7. Kukula kwa tuyere kumagwirizana ndi mtunda wochokera ku nsonga ya spinneret mpaka kumtunda wa mpeni wopumira, 1-2mm;
8, liwiro lozungulira screw ndi locheperako kapena laling'ono (kuthamanga kwa mphepo pang'ono, voliyumu yotulutsa mpweya ikhoza kukhala yaying'ono, kuthamanga kwa mphepo kwakukulu, voliyumu yotulutsa mpweya ikhoza kukhala yayikulu).
Zitatu: sinthani njira yochitira zinthu zosazolowereka
1. Ngati nsaluyo si yofewa pa kutentha kwakukulu komwe kumalimbikitsidwa, pakhoza kukhala vuto ndi kulowetsa kutentha kapena kuwongolera kutentha, pitirizani kukweza kutentha mpaka nsaluyo itakhala yofewa;
2. Ngati mpweya uli pansi pa 0.2mpa ndipo kutentha kwa mutu wa die kuli pafupifupi madigiri 210 kapena kuchepera, padzakhala chodabwitsa cha maluwa ouluka. N'zotheka kuti kusungunuka kwa PP spray yosungunula sikuli bwino, kapena kutentha kwake sikuli bwino, chiwonetsero cha mpweya sichili bwino, kapena kukula kwa njira yotulutsira mpweya ndi ngodya sizili bwino, kotero wopanga zida kapena wopanga zinthu zopangira ayenera kulumikizana naye kuti athetse vutoli;
3. Ndikoyenera kugwiritsa ntchito zipangizo zotentha pang'ono pa zipangizo zazikulu ndi zipangizo zotentha pang'ono pa zipangizo zazing'ono;
4. Kawirikawiri, ngati nsalu si yofewa ikawonjezedwa ku kutentha kwakukulu, kapena ikuyamba kusweka, kenako kutentha kumawonjezeka, nsaluyo imayamba kufewa. Kawirikawiri, pali vuto ndi chipangizocho, choncho tikukulangizani kuti mulankhule ndi wopanga zidazo, kapena pali vuto lalikulu la khalidwe ndi chipangizocho;
5. Kuwonjezera ma electret masterbatches nthawi zambiri kumafunika kufananizidwa ndi kusintha magawo oyenera a njira. Ma electret masterbatches osiyanasiyana ali ndi magawo osiyanasiyana ofanana a njira, omwe amatha kusinthidwa kuti akhale abwino kwambiri malinga ndi njira yosinthira mwachangu iyi, kenako nkuyerekeza ndi magwiridwe antchito;
6. Kuchuluka kwa electret masterbatch, mphamvu ya electrostatic idzakhala yabwino kwambiri. Komabe, mphamvu ya nsalu idzakhala yayikulu, kotero ndikofunikira kuti pakhale mgwirizano, ndipo cholinga chake ndi kupanga nsalu bwino.
Iv. Chivundikiro Chogwiritsira Ntchito (Kukhazikitsa kutentha)
1, kutentha kwa sikurufu: madigiri 190, madigiri 230, madigiri 230..., madigiri 230, madigiri 260;
2. Kutentha kwa die: madigiri 240, madigiri 240... madigiri 240;
3. Chosinthira chophimba mwachangu, pampu yoyezera, fyuluta ya mutu wa die: 245 °;
4. Kutentha kwa mphika wotenthetsera: madigiri 300, kutentha kwa mpweya wotentha: madigiri 220.
Ulusiwo ndi wosavuta kuupanga kukhala wokhuthala mumlengalenga, makamaka kutentha kwambiri, kotero nthawi zambiri, kutentha kwa mutu wa nkhungu ndi kutentha kwa mpweya wotentha ziyenera kukhala zochepa, kutentha kwa screw kuyenera kukhala kokwera, nthawi yomweyo, malo osefera, kutentha kuyenera kukhala kokwera, kuti muchepetse kuchuluka kwa mutu wa nkhungu.
Zisanu: Kufotokozera za kuchepa kwa mphamvu yamagetsi
Pofuna kupititsa patsogolo ntchito yosefera mpweya, chithandizo cha electret ndi kuwonjezera electret masterbatch zimafunikanso kuti ziwongolere mphamvu ya electrostatic adsorption ndikusefa tinthu tating'onoting'ono tomwe tili mu chonyamulira mpweya bwino.
1, nsalu yosungunuka ikatha kukonzedwa ndi mkati, kupatulapo mu masterbatch yomwe ingatenge electrostatic, PP yosungunuka imathanso kubweretsa electrostatic, kuwonjezera pang'ono mu masterbatch kwambiri pa lamba wa fyuluta, mphamvu ya electrostatic yonse ndi pafupifupi 10-20%, ndipo electrostatic ndi yokhazikika, pansi pa mikhalidwe yoyenera yosungira, kuchepa kwa mphamvu kumakhala pang'onopang'ono, ndipo PP yosungunuka imathanso kubweretsa magetsi ambiri osasinthasintha, ikhoza kukhala yothandiza kwambiri pakusefa, komanso kuwonongeka mwachangu;
2. Kuchepa kwa mphamvu zosefera sikufanana ndi kuchepa kwa mphamvu zamagetsi kwa electret mastermind, koma kuchepa kwa mphamvu zamagetsi kwa shotcrete PP yosungunuka kungapangitse mphamvu zosefera kuchepa mwachangu;
3. Nsalu yopangidwa pa kutentha kwambiri kwa mutu ndi mpweya wotentha imawoneka yofewa, koma kulimba kwake sikokwanira. Pakapita nthawi, nsaluyo idzakhala yopyapyala ndipo imapangitsa kuti mphamvu yosefera ichepe;
Chachisanu ndi chimodzi: njira yothetsera vuto la kukonza zotsatira zosefera
1, ngati mukufuna kupanga fyuluta kukhala yokhazikika, choyamba, sizimawonjezera zinthu zambiri mu masterbatch ndi processing conditions, zofunikira za melt-blown filter texture fundamental physics zimakhudza kwambiri, pamaziko a izi, mutha kulowa nawo mu masterbatch, osawonjezera zinthu mu processing, kuyesa kusiyana kwa fyuluta, zabwino kwambiri mu masterbatch musawonjezere zinthu, komabe zimatha kupangidwa kudzera mu processing ya static energy, kuti muwongolere fyuluta ya nsalu yosungunuka;
2. Kawirikawiri, mphamvu yoyambira yosefera ya nsalu yopopera yosungunuka iyenera kufika pa 60%-80%, kenako mphamvu yokhazikika yosefera ikhoza kupezeka kudzera mu kuwonjezera kwa electret masterbatch ndi chithandizo cha electret.
Zomwe zili pamwambapa ndi izi: njira yosinthira mwachangu nsalu yopanda ulusi yosungunuka, ndikuyembekeza kukuthandizani; Ndife afakitale yopanda nsalu yosungunuka, takulandirani kuti mukambirane ~
