Biodegradable polypropylene composite spunbond nonwoven lesela

Ka lebaka la sebopeho sa molek'hule sa khabone se le seng sa polypropylene, sebopeho sa eona sa molek'hule se batla se tsitsitse ebile ho thata ho se theola kapele. Le hoja lesela lena le bonolo la polypropylene spunbond nonwoven le thusa tlhahiso le bophelo ba batho, le boetse le baka tšilafalo e itseng ea tikoloho. Ka hona, ho lokisoa le ho etsa lipatlisiso tsa lesela la polypropylene composite spunbond nonwoven e sa lohoeng ho bohlokoa ka ho khetheha. Polylactic acid ke polima e ka bolang e nang le biocompatibility e ntle haholo le thepa ea mochini. E ka kopanngoa le lisebelisoa tse tala tsa polypropylene ho lokisa masela a sa lohoeng a polypropylene composite spunbond, kahoo a fokotsa tšilafalo ea tikoloho e bakoang ke masela a sa lohoeng a polypropylene spunbond.

Ts'ebetso ea lesela la polypropylene le kopantsoeng le biodegradable spunbond nonwoven

Ha ho ntse ho etsoa lesela le entsoeng ka biodegradable polypropylene composite spunbond nonwoven, lintlha tse kang lebelo la pompo ea metering, mocheso o chesang o bilikang le mocheso o ohiang li ka ba le tšusumetso e kholo linthong tsa 'mele tsa lesela la spunbond nonwoven. Fetola ho latela litlhoko tsa bareki joalo ka boima ba 'mele, botenya, matla a thata, joalo-joalo.

Tšusumetso ea lebelo la pompo ea metering

Ka ho beha lebelo le fapaneng la pompo ea metering, thepa ea faeba ea likhoele tse lokiselitsoeng tse kopantsoeng, joalo ka sekhahla sa mela, bophara ba fiber, le matla a fracture ea faeba, lia hlahlojoa ho fumana lebelo le nepahetseng la pompo ea metering bakeng sa ts'ebetso ea likhoele tse lokiselitsoeng tsa fiber. Ka nako e ts'oanang, ka ho beha lebelo le fapaneng la pompo ea metering ho sekaseka matšoao a ts'ebetso joalo ka boima, botenya, le matla a thata a lesela le lokiselitsoeng la spunbond nonwoven, lebelo le nepahetseng la pompo ea metering le ka fumanoa ka ho kopanya thepa ea fiber le thepa e sa lohoeng ea lesela le kopaneng la spunbond nonwoven.

Tšusumetso ea mocheso oa mocheso o chesang

Ka ho lokisa mekhahlelo e meng ea ts'ebetso ea ho itokisa le ho beha liloala tse fapaneng le mocheso bakeng sa ho bilika ho chesang, tšusumetso ea mocheso o chesang oa mocheso holim'a thepa ea li-filaments tse lokiselitsoeng tse entsoeng ka motsoako li ithutoa le ho hlahlojoa. Ha mocheso o matlafatsang oa mocheso oa leloala le thethefatsang o le tlase haholo, likhoele tse chesang li ke ke tsa qhibiliha ka ho feletseng, e leng se etsang hore ho be le mekhoa e sa hlakang le boikutlo bo bobe ba matsoho. Ka mohlala, ho lokisoa ha biodegradable polylactic acid / additive / polypropylene composite spunbond e sa lohiloeng, ha mocheso o chesang o matlafatsang o fihla ho 70 ℃, likhoele tse entsoeng ka fiber li hlakile 'me ho na le ho khomarela hanyenyane ho moqolo, kahoo mocheso oa 70 ℃ o fihlile moeling o ka holimo oa mocheso.

Tšusumetso ea mocheso o ohiang

Tšusumetso ea lithempereichara tse fapaneng tse ohiang holim'a thepa ea khoele e kopantsoeng ea khoele, bophara ba fiber, le matla a ho robeha ha fiber, hammoho le thepa ea lesela le sa lohiloeng le entsoeng ka polypropylene le entsoeng ka biodegradable spunbond, ha ho ntse ho lokisa maemo a mang a tšebetso.

Phallo ea theknoloji ea ts'ebetso ea lesela la polypropylene le kopantsoeng le biodegradable spunbond nonwoven
