Biodegradable polypropylene composite spunbond nonwoven nsalu

Chifukwa cha kuchuluka kwa mpweya wa carbon single bond ma cell a polypropylene, mawonekedwe ake a cell ndi okhazikika komanso ovuta kutsitsa mwachangu. Ngakhale nsalu yosavuta imeneyi ya polypropylene spunbond nonwoven imapangitsa kuti anthu azitha kupanga komanso kukhala ndi moyo, imayambitsanso kuipitsa chilengedwe. Chifukwa chake, kukonza ndi kufufuza kwa nsalu zowongoka komanso zowola za polypropylene composite spunbond nonwoven n'kofunika kwambiri. Polylactic acid ndi polima wosasinthika wokhala ndi biocompatibility yabwino kwambiri komanso makina. Zitha kuphatikizidwa ndi zida za polypropylene pokonzekera nsalu za polypropylene composite spunbond nonwoven, potero kuchepetsa kuipitsidwa kwa chilengedwe chifukwa cha nsalu za polypropylene spunbond nonwoven.

Magwiridwe a biodegradable polypropylene composite spunbond nonwoven nsalu

Pakukonza biodegradable polypropylene composite spunbond nonwoven nsalu, zinthu monga liwiro la mpope metering, otentha anagubuduza kutentha, ndi kupota kutentha akhoza kukhudza kwambiri katundu thupi la spunbond nonwoven nsalu. Sinthani molingana ndi zomwe makasitomala amafuna monga kulemera, makulidwe, mphamvu zamakokedwe, ndi zina.

Mphamvu ya pampu ya metering

Pokhazikitsa liwiro la pampu ya metering, mawonekedwe a ulusi wa ulusi wopangidwa ndi gulu lokonzekera, monga kachulukidwe kakang'ono, kuchuluka kwa fiber, ndi mphamvu yakuphwanyidwa kwa ulusi, amawunikidwa kuti adziwe kuthamanga kwapampu ya metering kuti agwiritse ntchito ma filaments opangidwa. Panthawi imodzimodziyo, poika maulendo osiyanasiyana a pampu ya metering kuti afufuze zizindikiro zogwira ntchito monga kulemera, makulidwe, ndi mphamvu zowonongeka za nsalu yopangidwa ndi spunbond nonwoven, kuthamanga kwapampu koyenera kungathe kupezedwa mwa kuphatikiza katundu wa CHIKWANGWANI ndi zinthu zopanda nsalu za nsalu yopangidwa ndi spunbond nonwoven.

Mphamvu ya kutentha kugubuduza kutentha

Pokonza magawo ena okonzekera ndikuyika mphero zosiyanasiyana ndi kutentha kwa kugudubuza kotentha, chikoka cha kutentha kwa kutentha kwa kutentha kwazinthu zamagulu okonzeka opangidwa ndi fiber filaments amaphunzira ndi kusanthula. Kutentha kwa mpheroyo kukakhala kotsika kwambiri, ulusi wotentha sungathe kusungunuka, zomwe zimapangitsa kuti pakhale mawonekedwe osadziwika bwino komanso kusamva bwino kwa manja. Kutengera kukonzekera biodegradable polylactic asidi / zowonjezera / polypropylene gulu spunbond sanali nsalu nsalu mwachitsanzo, pamene otentha Kugubuduza chilimbikitso kutentha kufika 70 ℃, gulu CHIKWANGWANI mizere bwino ndipo pali kumamatira pang'ono mpukutuwo, kotero 70 ℃ malire afika reinfor kumtunda kutentha.

Mphamvu ya kupota kutentha

Chikoka cha kutentha kosiyanasiyana kozungulira pamtundu wa kachulukidwe ka ulusi wophatikizika wa ulusi, kuchuluka kwa ulusi, ndi mphamvu ya fracture ya ulusi, komanso mphamvu ya biodegradable polypropylene composite spunbond nonwoven nsalu, ndikukonza magawo ena okonzekera.

Ukadaulo waukadaulo wamayendedwe a biodegradable polypropylene composite spunbond nonwoven nsalu

(1) Kagawo polylactic asidi, polypropylene, ndi maleic anhydride kumezanitsa copolymer ndi kusakaniza mu milingo yoyenera;

(2) Gwiritsirani ntchito chopopera chotulutsa ng'oma ndi makina opota popota;

(3) Sefa kudzera fyuluta yosungunula ndikupanga mauna pansi pa mpope wa metering, chowumitsira chowumitsira, ndi kutambasula kothamanga kwa mpweya wothamanga kwambiri;

(4) Pangani nsalu zoyenerera za spunbond zosawomba kudzera muzitsulo zomangirira zotentha, zokhotakhota, ndi kudula mobwerera.
