Indwangu ye-Spunbond polypropylene

Indwangu ye-Oue spunbond nonwoven iwuhlobo lwendwangu engalukiwe eyenziwe ngemicu ye-thermoplastic polypropylene (PP) ehlanganiswe ndawonye ngenqubo eshisayo. Inqubo ihilela ukukhipha imicu ye-PP, bese iphothwa futhi ibekwe phansi ngephethini engahleliwe ukuze kwakhiwe iwebhu. Iwebhu ibe isihlanganiswa ndawonye ukuze yakhe indwangu eqinile nehlala isikhathi eside.

Izici ze-PP zaphotha indwangu engalukiwe

Indwangu engalukiwe ye-polypropylene spunbond inezici zokulula, ukuphefumula, ukuqina, ukuvimbela amanzi, i-anti-static, nokuvikelwa kwemvelo.Indwangu engalukiwe ye-Polypropylene spunbond iyinto engasindi enezici zesisindo esilula kanye namandla aqinile okuthwala umthwalo. Lokhu kuyenza ibe enye impahla ekahle, elungele izinkambu eziningi ezifana nokunakekelwa kwezempilo, imikhiqizo yasendlini, njll. Khonamanjalo, ngenxa yokukhanya kwayo, kulula kakhulu ukuyiphatha nokuyifaka.

pp spunbond ukusetshenziswa kwendwangu engalukiwe

Indwangu engalukiwe ye-PP ye-spunbond inokusetshenziswa okubanzi kuyo yonke indawo yezolimo, ukwakhiwa, ukupakisha, ama-geotextiles, ezezimoto, impahla yasekhaya. Indwangu engalukiwe eyenziwe nge-spunbonded ingumkhiqizo onamandla okuthuthuka, osebenzisa ngokugcwele izinzuzo zemicu njengezinto zokunakekelwa kwempilo. Kungumkhiqizo wokuqondiswa kwemboni esafufusa okwakhiwa ukuhlanganiswa nokuphambana kwemikhakha eminingi nobuchwepheshe. Lokhu kuhlanganisa izingubo zokuhlinza, izingubo zokuzivikela, izikhwama zokubulala amagciwane, imaski, amanabukeni, izindwangu zasendlini, izindwangu zokusula, amathawula obuso obumanzi, amathawula omlingo, amaroli ezicubu ezithambile, imikhiqizo yobuhle, ama-sanitary pads, nezindwangu zangasese ezilahlwayo.

Ukuqonda inqubo ye-spin bonding

Indlela ye-spunbonding, esetshenziselwa ukwenza izindwangu ezingalukiwe, ihlanganisa ukukhipha ama-polymers we-thermoplastic, ngokuvamile i-polypropylene (PP), ibe imicu eqhubekayo. Ngemuva kwalokho, ama-filaments ahlelwa abe yisimo sewebhu futhi ahlanganiswe ndawonye ukuze enze indwangu eqinile, ehlala isikhathi eside. Izici eziningi ezifiselekayo, njengamandla aphezulu, ukuphefumula, ukumelana namanzi, nokumelana namakhemikhali, zikhona kumphumela wendwangu ye-PP spunbond nonwoven. Lena incazelo enemininingwane yenqubo ye-spunbonding:

1. Ukukhishwa kwama-polymers: Ukukhishwa kwe-polymer nge-spinneret, ngokuvamile ngendlela yama-pellets, kuyisinyathelo sokuqala kule nqubo. I-polymer encibilikisiwe iqhutshwa ngaphansi kwengcindezi ngokusebenzisa izimbobo eziningi ezincane ze-spinneret.

2. I-Filament spinning: I-polymer iyanwetshwa futhi ipholiswe njengoba iphuma ku-spinneret ukuze yenze imicu eqhubekayo. Ngokuvamile, le micu inobubanzi obuyi-15-35 microns.

3. Ukwakheka kwewebhu: Ukuze kwakhiwe iwebhu, imicu isuke iqoqwa ngephethini engaqondakali ebhandeni elihambayo lokuthutha noma isigubhu. Isisindo sewebhu ngokuvamile singu-15–150 g/m².

4. Ukubopha: Ukuhlanganisa imicu ndawonye, ​​iwebhu ivalwa ngokulandelayo ukushisa, ukucindezela, noma amakhemikhali. Amasu amaningi, njengokuhlanganisa ukushisa, ukuhlanganisa amakhemikhali, noma ukudinga imishini, kungasetshenziswa ukufeza lokhu.

5. Ukuqeda: Ngemva kokubopha, indwangu ngokuvamile i-calender noma inikezwe isiphetho ukuze kuthuthukiswe izici zayo zokusebenza, njengokumelana kwamanzi, ukumelana ne-UV.
