Izinqumo Zokusetshenziswa Kuhlelo Lokususa I-PP Monofilament: Kuthuthela Ukukhula Okuphakeme Emaphakethini Onjalo
U umzamo wesayensi kanye nomzamo wasekhaya kuzohlala kuyisiseko sokusebenza okukhanya kwezinhlelo zokunquma kwamaduli e-PP. Amaduli aqondene avela kulezi zinhlelo, ayisiseko esibaluleke kakhulu ekwenzeni izimpahla ezisetshenziswa kabusha njengebhage yoshopha, amabhage wamathambo/izithelo, nezimpahla zokucisha—ezinikezela usizo oluphakade emsebenzini womhlaba. Ngaphandle kwalokho, ngokuthi imbono yesitinga siphatha iplastics esetshenziswa isikhathi esisodwa, ukuguquka kwezimpahla ezinokubuyiselwa njengezinhlelo zokunquma kwamaduli e-PP ezinzile kuye kusondeza. Futhi, inkinga yale nhlelo yokulungisa izimo zokusebenza ukuze ikhwele amaduli angafani ngokwobuchane nobukhathaza kubanzi kumandla, kubangela ukuthuthuka kwayo emseleni wokucisha (njengezihluku zokucisha amavuni nezihluku zokucisha amanzi), okwenzela ukuthi iphinde iphakeme kakhulu emseleni wokushayela.
Kwi isayensi esisha sendlu , izinhawu zokugcwalisa i-PP monofilament zihlale kuthole ubumbano obhokhwele ekhona ukuthola izinto ezinezindima eziphambili kwezimali. Lezi zinhawu zakhela ama-monofilament ase-PP amasebenzayo emashade netshebeza, amathikithiki okulima, amathikithiki okukhuphuka komthombo, namathikithiki okukhuphuka kwamafilmu—kudingeka kakhulu ukulima, ukulawula izimo zokuzalwa, nokuthuthukisa inzuzo yezimali. Ngokuthuthukisa kwezimali ezinkulu nezemfundo ethu, kukhona ubumbano obhokhile ekhona ukuthola ama-monofilament ase-PP angakhathazeki kwi-radiation ye-UV, ukucoriswa, nokusheshayo. Inhawu yokugcwalisa inokwenzela ukwakha kakhulu nokuhlengahlenga (umzekelo, ukuhlungwa kwebhodlela yomthombo ukufanisana nesidingo sokukhuphuka komthombo) ibaluleke kakhulu kule ndlela, ngelishwa isivumelwano esinikezwayo kuzinto olunye lwemvelo okuhle kakhulu kwezimali kusiza kakhulu kuleli qondo.
U izinsiza ephuthumayo nezahlelekile kwenza izinhlayiya ezintsha zokuthutha kumgwa wokugcwalisa we-PP monofilament. Kukulungiselelo, i-PP monofilaments isetshenziselwa emathathakini (ekunqoleni izindlu nekuqina kwezimali) nokuxhumana komlilo, kubizwa ngokuthutha kwemfundo yobuchwepheshe bempilo. Kude kwasendlezeni yokuthutha, ihlala yisilingo sokuphatha kwezimpahla zokulahla phansi kwebhodi namakhanda okuvila, lapho kudingeka ukuba kuncane kakhulu nokukhathazeleka kwezinkalabala eziningi. Nangoba kuqukethwe kwezimali eziphucayo, i-PP monofilaments isetshenziselwa kuzimpahla zokulahla phansi kwezokwelashwa kwe-lithium-ion. Lezi zimo ezihleli kakhulu zidinga ukuhlawulwa okucacile kudayimitha kanye nesilingo se-monofilament, futhi i-PP monofilament extrusion lines—eziqukethe izinhlelo ezihlelekile zokuhlela izinkalabala kanye nezinhlelo zokuhlola ubumnandi phakathi kwesikhathi—zingakhipha izinhlayiya eziphathelene kahle, eziphathelene kahle, zikunciphise ukuthandabuka kumateriali engenakho
