Hunhu hwe spunbond pp nonwoven jira

1. PP spunbond isiri-yakarukwa jira rine maitiro ekudzivirira mvura, kufema, kushanduka, kusapisa, kusina chepfu uye kusagumbura, uye mavara akapfuma. Kana iyo midziyo ikaiswa kunze uye yakaora nekasikirwo, hupenyu hwayo hwepamusoro ndeyemazuva makumi mapfumbamwe chete. Kana ikaiswa mumba uye yakaora mukati memakore mashanu, haina chepfu, haina kunhuwa, uye haina zvinhu zvakasara kana yapiswa, nokudaro isingasvibise nharaunda. Nokudaro, kuchengetedzwa kwezvakatipoteredza kunobva kune izvi.

2. PP jira risiri rakarukwa rine hunhu hwepfupi process kuyerera, kukurumidza kugadzira kukurumidza, goho rakakura, mutengo wakaderera, kushandiswa kwakakura, uye akawanda mbishi zvinyorwa.

Kuvandudzwa kweSpunbond pp nonwoven jira

Iyo PP isiri-yakarukwa machira indasitiri muChina yakasimukira nekukurumidza, ikawana kukurumidza kukura mukugadzira nekutengesa, asi kwave kune mamwe matambudziko panguva yekuvandudza. Zvikonzero zvezvinetso senge yakaderera mechanization mwero uye inononoka maindasitiri maitiro ane akawanda. Pamusoro pezvinhu zvakaita senge manejimendi sisitimu uye kushambadzira, kusimba kwehunyanzvi hwekuita uye kushomeka kwekutsvagisa kwekutanga ndizvo zvipingamupinyi zvikuru. Kunyangwe humwe ruzivo rwekugadzira rwakaunganidzwa mumakore achangopfuura, hachisati chave nedzidziso uye zvakaoma kutungamira kugadzirwa kwemichina.

Chii chinonzi kugadzikana kwemakemikari espunbond pp nonwoven jira

1. Kuita muviri

PP isiri-yakarukwa spunbond jira isiri-chepfu uye isina kunhuhwirira mukaka chena yakakwira crystalline polymer, inova imwe yemhando dzakareruka dzemapurasitiki. Inonyanya kugadzikana kumvura uye ine chiyero chekutora mvura che 0.01% chete mushure memaawa gumi nemana mumvura. Huremu hwemamorekuru hunobva pa80000 kusvika 150000, nechimiro chakanaka. Zvisinei, nekuda kwehupamhi hwehupamhi hwehupamhi, zvigadzirwa zvepakutanga zvemadziro zvinowanzoita indentation, uye ruvara rwepamusoro rwezvigadzirwa zvakanaka, zvichiita kuti zvive nyore kuisa.

2. Mechanical properties

Spunbond pp nonwoven jira rine hutsanana hwepamusoro, chimiro chenguva dzose, uye nekudaro ine yakanakisa michina zvimiro. Simba rayo, kuoma, uye elasticity zvakakwirira pane yakakwirira-density PE. Chimiro chakakurumbira ndechekuramba kwakasimba pakukotama kuneta, ine yakaoma friction coefficient yakafanana nenylon, asi isina kunaka senylon pasi pemafuta ekuzora.

3. Thermal performance

Spunbond pp nonwoven jira rine kunaka kwekudzivirira kupisa, ine nzvimbo yekunyungudika ye164-170 ℃. Chigadzirwa chacho chinogona kuiswa disinfected uye sterilized patembiricha iri pamusoro pe100 ℃. Pasina simba rekunze, haina kukanganisa kunyange pa150 ℃. The embrittlement tembiricha iri -35 ℃, uye embrittlement kunoitika pazasi -35 ℃, ine yakaderera kupisa kuramba kupfuura PE.

4. Kuita kwemagetsi

Spunbond pp nonwoven jira rine yakanakisa high-frequency insulation performance. Nekuda kweiyo inenge isina kunyura kwemvura, kushanda kwayo kwekudzivirira hakukanganisi nehunyoro, uye ine yakakwira dielectric coefficient. Nekuwedzera kwekushisa, inogona kushandiswa kugadzira zvigadzirwa zvemagetsi zvinopisa. Mhepo yekuputsika zvakare yakanyanya kwazvo, ichiita kuti ive yakakodzera kune zvigadzirwa zvemagetsi, etc. Good voltage resistance uye arc resistance, asi high static magetsi uye kuchembera zviri nyore paunosangana nemhangura.

5. Weathering kuramba

Spunbond pp nonwoven jira rinonzwa zvakanyanya kune ultraviolet mwaranzi. Kuwedzera zinc oxide thiopropionate lauric acid ester uye kabhoni dema kunge mukaka chena mafirita anogona kuvandudza kuchembera kwayo.
